Integrative Analysis Identifies Four Molecular and Clinical Subsets in Uveal Melanoma
<h2>Summary</h2> Comprehensive multiplatform analysis of 80 uveal melanomas (UM) identifies four molecularly distinct, clinically relevant subtypes: two associated with poor-prognosis monosomy 3 (M3) and two with better-prognosis disomy 3 (D3). We show that <i>BAP1</i> loss follows M3 occurrence and correlates with a global DNA methylation state that is distinct from D3-UM. Poor-prognosis M3-UM divide into subsets with divergent genomic aberrations, transcriptional features, and clinical outcomes. We report change-of-function <i>SRSF2</i> mutations. Within D3-UM, <i>EIF1AX</i>- and <i>SRSF2</i>/<i>SF3B1</i>-mutant tumors have distinct somatic copy number alterations and DNA methylation profiles, providing insight into the biology of these low- versus intermediate-risk clinical mutation subtypes.

<i>SF3B1</i> Mutations Are Associated with Alternative Splicing in Uveal Melanoma
Abstract Uveal melanoma, the most common eye malignancy, causes severe visual morbidity and is fatal in approximately 50% of patients. Primary uveal melanoma can be cured by surgery or radiotherapy, but the metastatic disease is treatment refractory. To understand comprehensively uveal melanoma genetics, we conducted single-nucleotide polymorphism arrays and whole-genome sequencing on 12 primary uveal melanomas. We observed only approximately 2,000 predicted somatic single-nucleotide variants per tumor and low levels of aneuploidy. We did not observe an ultraviolet radiation DNA damage signature, but identified SF3B1 mutations in three samples and a further 15 mutations in an extension cohort of 105 samples. SF3B1 mutations were associated with good prognosis and were rarely coincident with BAP1 mutations. SF3B1 encodes a component of the spliceosome, and RNA sequencing revealed that SF3B1 mutations were associated with differential alternative splicing of protein coding genes, including ABCC5 and UQCC, and of the long noncoding RNA CRNDE. Significance: Our data show that despite its dismal prognosis, uveal melanoma is a relatively simple genetic disease characterized by recurrent chromosomal losses and gains and a low mutational burden. We show that SF3B1 is recurrently mutated in uveal melanoma, and the mutations are associated with aberrant alternative splicing. Cancer Discov; 3(10); 1122–9. ©2013 AACR.

The American Brachytherapy Society consensus guidelines for plaque brachytherapy of uveal melanoma and retinoblastoma
To present the American Brachytherapy Society (ABS) guidelines for plaque brachytherapy of choroidal melanoma and retinoblastoma.An international multicenter Ophthalmic Oncology Task Force (OOTF) was assembled to include 47 radiation oncologists, medical physicists, and ophthalmic oncologists from 10 countries. The ABS-OOTF produced collaborative guidelines, based on their eye cancer-specific clinical experience and knowledge of the literature. This work was reviewed and approved by the ABS Board of Directors as well as within the journal's peer-reivew process.The ABS-OOTF reached consensus that ophthalmic plaque radiation therapy is best performed in subspecialty brachytherapy centers. Quality assurance, methods of plaque construction, and dosimetry should be consistent with the 2012 joint guidelines of the American Association of Physicists in Medicine and ABS. Implantation of plaque sources should be performed by subspecialty-trained surgeons. Although there exist select restrictions related to tumor size and location, the ABS-OOTF agreed that most melanomas of the iris, ciliary body, and choroid could be treated with plaque brachytherapy. The ABS-OOTF reached consensus that tumors with gross orbital extension and blind painful eyes and those with no light perception vision are unsuitable for brachytherapy. In contrast, only select retinoblastomas are eligible for plaque brachytherapy. Prescription doses, dose rates, treatment durations, and clinical methods are described.Plaque brachytherapy is an effective eye and vision-sparing method to treat patients with intraocular tumors. Practitioners are encouraged to use ABS-OOTF guidelines to enhance their practice.

Germline BAP1 Mutations Predispose to Renal Cell Carcinomas
The genetic cause of some familial nonsyndromic renal cell carcinomas (RCC) defined by at least two affected first-degree relatives is unknown. By combining whole-exome sequencing and tumor profiling in a family prone to cases of RCC, we identified a germline BAP1 mutation c.277A>G (p.Thr93Ala) as the probable genetic basis of RCC predisposition. This mutation segregated with all four RCC-affected relatives. Furthermore, BAP1 was found to be inactivated in RCC-affected individuals from this family. No BAP1 mutations were identified in 32 familial cases presenting with only RCC. We then screened for germline BAP1 deleterious mutations in familial aggregations of cancers within the spectrum of the recently described BAP1-associated tumor predisposition syndrome, including uveal melanoma, malignant pleural mesothelioma, and cutaneous melanoma. Among the 11 families that included individuals identified as carrying germline deleterious BAP1 mutations, 6 families presented with 9 RCC-affected individuals, demonstrating a significantly increased risk for RCC. This strongly argues that RCC belongs to the BAP1 syndrome and that BAP1 is a RCC-predisposition gene.

Histopathologic risk factors in retinoblastoma: A retrospective study of 172 patients treated in a single institution
Microscopic extrascleral involvement and involvement of optic nerve resection line are accepted risk factors for orbital and/or metastatic disease from retinoblastoma. Conversely, choroidal and retrolaminar optic nerve involvement are questionable risk factors. The aim of this retrospective study was to define the histopathologic risk factors for orbital and/or metastatic disease in patients treated by first-line enucleation.Histopathologic review of 172 evaluable patients treated at Institut Curie between 1977 and 1990 determined the degree of choroidal (minimal or massive), scleral (intra- or extrascleral), optic nerve (prelaminar, retrolaminar with or without resection line involvement), and anterior chamber invasion. The degree of differentiation was also analyzed. The log rank test was used for univariate analysis and the Cox regression model was used for multivariate analysis. RESULTS. Eighty-seven percent of the 172 patients were disease free at 3 years. Twenty-three patients developed retinoblastoma recurrence. The disease-free survival was significantly different among the five subgroups of choroidal or scleral invasion (P = 3 x 10(-3). The differences among the four subgroups of optic nerve invasion were also significant (P = 10(-4)). Classical factors were confirmed in our series (extrascleral involvement and involvement of optic nerve resection line). Multivariate analysis of the 149 patients without these classical risk factors revealed two factors that increase the risk of orbital and/or metastatic disease: massive choroidal invasion and postlaminar optic nerve involvement.In our experience, retrolaminar optic nerve involvement, with free resection line, and massive choroidal invasion significantly increase the risk for orbital and/or metastatic disease.

Proton beam radiotherapy for uveal melanoma: Results of Curie Institut–Orsay Proton Therapy Center (ICPO)
Purpose: This study reports the results of proton beam radiotherapy based on a retrospective series of patients treated for uveal melanoma at the Orsay Center. Methods and Materials: Between September 1991 and September 2001, 1,406 patients with uveal melanoma were treated by proton beam radiotherapy. A total dose of 60 cobalt Gray equivalent (CGE) was delivered in 4 fractions on 4 days. Survival rates were determined using Kaplan–Meier estimates. Prognostic factors were determined by multivariate analysis using the Cox model. Results: The median follow-up was 73 months (range, 24–142 months). The 5-year overall survival and metastasis-free survival rates were 79% and 80.6%, respectively. The 5-year local control rate was 96%. The 5-year enucleation for complications rate was 7.7%. Independent prognostic factors for overall survival were age (p < 0.0001), gender (p < 0.0003), tumor site (p < 0.0001), tumor thickness (p = 0.02), tumor diameter (p < 0.0001), and retinal area receiving at least 30 CGE (p = 0.003). Independent prognostic factors for metastasis-free survival were age (p = 0.0042), retinal detachment (p = 0.01), tumor site (p < 0.0001), tumor volume (p < 0.0001), local recurrence (p < 0.0001), and retinal area receiving at least 30 CGE (p = 0.002). Independent prognostic factors for local control were tumor diameter (p = 0.003) and macular area receiving at least 30 CGE (p = 0.01). Independent prognostic factors for enucleation for complications were tumor thickness (p < 0.0001) and lens volume receiving at least 30 CGE (p = 0.0002). Conclusion: This retrospective study confirms that proton beam radiotherapy ensures an excellent local control rate. Further clinical studies are required to decrease the incidence of postirradiation ocular complications.

Surgical management of liver metastases from uveal melanoma: 16 years' experience at the Institut Curie
Background Uveal melanoma is characterised by a high prevalence of liver metastases and a poor prognosis. Aim To review the evolving surgical management of this challenging condition at a single institution over a 16-year period. Patients and Methods Between January 1991 and June 2007, among 3873 patients with uveal melanoma, 798 patients had liver metastases. We undertook a detailed retrospective review of their clinical records and surgical procedures. The data was evaluated with both uni- and multivariate statistical analysis for predictive survival indicators. Results 255 patients underwent surgical resection. The median interval between ocular tumour diagnosis and liver surgery was 68 months (range 19–81). Liver surgery was either microscopically complete (R0; n=76), microscopically incomplete (R1; n=22) or macroscopically incomplete (R2; n=157). The median overall postoperative survival was 14 months, but increased to 27 months when R0 resection was possible. With multivariate analysis, four variables were found to independently correlate with prolonged survival: an interval from primary tumour diagnosis to liver metastases >24 months, comprehensiveness of surgical resection (R0), number of metastases resected (≤4) and absence of miliary disease. Conclusions Surgical resection, when possible, is able to almost double the survival and appears at present the optimal way of improving the prognosis in metastatic uveal melanoma. Advances in medical treatments will be required to further improve survival.

Detection rate and prognostic value of circulating tumor cells and circulating tumor DNA in metastatic uveal melanoma
Circulating tumor cells (CTCs) and circulating tumor DNA (ctDNA) have been recently investigated in several cancer types, but their respective clinical significance remains to be determined. In our prospective study, we compared the detection rate and the prognostic value of these two circulating biomarkers in patients with metastatic uveal melanoma. GNAQ/GNA11 mutations were characterized in archived tumor tissue. Using a highly sensitive and mutation‐specific bidirectional pyrophosphorolysis‐activated polymerization (bi‐PAP) technique, GNAQ c.626A&gt;T, GNAQ c.626A&gt;C and GNA11 c.626A&gt;T copy numbers were quantified in plasma from 12 mL of blood. CTCs were detected at the same time in 7.5 mL of blood by the CellSearch® technique. Patient characteristics and outcome were prospectively collected. CTCs (≥1) were detected in 12 of the 40 included patients (30%, range 1–20). Among the 26 patients with known detectable mutations, ctDNA was detected and quantified in 22 (84%, range 4–11,421 copies/mL). CTC count and ctDNA levels were associated with the presence of miliary hepatic metastasis ( p = 0.004 and 0.03, respectively), with metastasis volume ( p = 0.005 and 0.004) and with each other ( p &lt; 0.0001). CTC count and ctDNA levels were both strongly associated with progression‐free survival ( p = 0.003 and 0.001) and overall survival ( p = 0.0009 and &lt;0.0001). In multivariate analyses, ctDNA appeared to be a better prognostic marker than CTC. In conclusion, ctDNA and CTC are correlated and both have poor prognostic significance. CTC detection can be performed in every patient but, in patients with detectable mutations, ctDNA was more frequently detected than CTC and has possibly more prognostic value.

Retinoblastoma
Retinoblastoma is a rare eye tumor of childhood that arises in the retina. It is the most common intraocular malignancy of infancy and childhood; with an incidence of 1/15,000-20,000 live births. The two most frequent symptoms revealing retinoblastoma are leukocoria and strabismus. Iris rubeosis, hypopyon, hyphema, buphthalmia, orbital cellulites and exophthalmia may also be observed. Sixty per cent of retinoblastomas are unilateral and most of these forms are not hereditary (median age at diagnosis two years). Retinoblastoma is bilateral in 40% of cases (median age at diagnosis one year). All bilateral and multifocal unilateral forms are hereditary. Hereditary retinoblastoma constitutes a cancer predisposition syndrome: a subject constitutionally carrying an RB1 gene mutation has a greater than 90% risk of developing retinoblastoma but is also at increased risk of developing other types of cancers. Diagnosis is made by fundoscopy. Ultrasound, magnetic resonance imaging (MRI) and computed tomography (CT) scans may contribute to diagnosis. Management of patients with retinoblastoma must take into account the various aspects of the disease: the visual risk, the possibly hereditary nature of the disease, the life-threatening risk. Enucleation is still often necessary in unilateral disease; the decision for adjuvant treatment is taken according to the histological risk factors. Conservative treatment for at least one eye is possible in most of the bilateral cases. It includes laser alone or combined with chemotherapy, cryotherapy and brachytherapy. The indication for external beam radiotherapy should be restricted to large ocular tumors and diffuse vitreous seeding because of the risk of late effects, including secondary sarcoma. Vital prognosis, related to retinoblastoma alone, is now excellent in patients with unilateral or bilateral forms of retinoblastoma. Long term follow-up and early counseling regarding the risk of second primary tumors and transmission should be offered to retinoblastoma patients.

Staging of Ciliary Body and Choroidal Melanomas Based on Anatomic Extent
Purpose To refine the anatomic classification and staging of ciliary body and choroidal melanomas in the TNM classification. Patients and Methods Tumor largest basal diameter and thickness of 7,369 patients were analyzed based on registry data from five ocular oncology centers. T categories were derived empirically by dividing data into blocks representing 3- × 3-mm fractions. Blocks with similar survival were grouped together so that no T category comprised a large majority of tumors, and each was uniform in survival, using randomly drawn 60% building and 40% validation data sets. Presence of ciliary body involvement (CBI) and extraocular extension (EXE) was analyzed among 5,403 patients to define T subcategories. Stages were generated by iteratively combining subcategories with similar survival. Results Of the 7,369 tumors analyzed, 24% were classified as T1, 33% as T2, 31% as T3, and 12% as T4. Ten-year Kaplan-Meier survival estimates for the T categories were 89%, 77%, 58%, and 39%, respectively (P &lt; .001). Survival of patients in four subcategories based on presence or absence of CBI and EXE differed significantly within each T category (P = .018 for T1; P &lt; .001 for T2 to T4). EXE exceeding 5 mm in largest diameter carried a worse prognosis than smaller extensions (P &lt; .001) and was assigned a separate subcategory. Ten-year Kaplan-Meier survival estimates for stages I, IIA to IIB, and IIIA to IIIC were 88%, 80%, 67%, 45%, 27%, 10%, respectively (P &lt; .001). Conclusion This evidence-based anatomic classification provides a basis for staging ciliary body and choroidal melanomas in the seventh edition of the Cancer Staging Manual of the American Joint Committee on Cancer.

High PTP4A3 Phosphatase Expression Correlates with Metastatic Risk in Uveal Melanoma Patients
Abstract A high percentage of uveal melanoma patients develop metastatic tumors predominantly in the liver. We studied the molecular profiles derived from gene expression microarrays and comparative genomic hybridization microarrays, to identify genes associated with metastasis in this aggressive cancer. We compared 28 uveal melanomas from patients who developed liver metastases within three years of enucleation with 35 tumors from patients without metastases or who developed metastases more than 3 years after enucleation. Protein tyrosine phosphatase type IV A member 3 (PTP4A3/PRL3), was identified as a strong predictor of metastasis occurrence. We demonstrated that the differential expression of this gene, which maps to 8q24.3, was not merely a consequence of 8q chromosome overrepresentation. PTP4A3 overexpression in uveal melanoma cell lines significantly increased cell migration and invasiveness in vivo, suggesting a direct role for this protein in metastasis. Our findings suggest that PTP4A3 or its cellular substrates could constitute attractive therapeutic targets to treat metastatic uveal melanomas. Cancer Res; 71(3); 666–74. ©2010 AACR.

Establishment and Characterization of a Panel of Human Uveal Melanoma Xenografts Derived from Primary and/or Metastatic Tumors
Uveal melanoma is the most common primary intraocular malignant tumor in adults and is defined by a poor natural outcome, as 50% of patients die from metastases. The aim of this study was to develop and characterize a panel of human uveal melanoma xenografts transplanted into immunodeficient mice.Ninety tumor specimens were grafted into severe combined immunodeficient mice, and 25 transplantable xenografts were then established (28%). Relationship between tumor graft and clinical, biological, and therapeutic features of the patients included were investigated. Characterization of 16 xenografts included histology, molecular analyses by immunohistochemistry, genetic alteration analysis (single-nucleotide polymorphism), and specific tumor antigen expression by quantitative reverse transcription-PCR. Pharmacologic characterization (chemosensitivity) was also done in four models using two drugs, temozolomide and fotemustine, currently used in the clinical management of uveal melanoma.Take rate of human uveal melanoma was 28% (25 of 90). Tumor take was independent of size, histologic parameters, or chromosome 3 monosomy but was significantly higher in metastatic tumors. Interestingly, in vivo tumor growth was prognostic for a lower metastasis-free survival in patients with primary tumors. A high concordance between the patients' tumors and their corresponding xenografts was found for all parameters tested (histology, genetic profile, and tumor antigen expression). Finally, the four xenografts studied displayed different response profiles to chemotherapeutic agents.Based on these results, this panel of 16 uveal melanoma xenografts represents a useful preclinical tool for both pharmacologic and biological assessments.

Genomic Profiling and Identification of High-Risk Uveal Melanoma by Array CGH Analysis of Primary Tumors and Liver Metastases
Incurable metastases develop in approximately 50% of patients with uveal melanoma (UM). The purpose of this study was to analyze genomic profiles in a large series of ocular tumors and liver metastases and design a genome-based classifier for metastatic risk assessment.A series of 86 UM tumors and 66 liver metastases were analyzed by using a BAC CGH (comparative genomic hybridization) microarray. A clustering was performed, and correlation with the metastatic status was sought among a subset of 71 patients with a minimum follow-up of 24 months. The status of chromosome 3 was further examined in the tumors, and metastases with disomy 3 were checked with an SNP microarray. A prognostic classifier was constructed using a log-linear model on minimal regions and leave-one-out cross-validation.The clustering divides the groups of tumors with disomy 3 and monosomy 3 into two and three subgroups, respectively. Same subgroups are found in primary tumors and in metastases, but with different frequencies. Isolated monosomy 3 was present in 0% of metastatic ocular tumors and in 3% of metastases. The highest metastatic rate in ocular tumors was observed in a subgroup defined by the gain of 8q with a proximal breakpoint, and losses of 3, 8p, and 16q, also most represented in metastases. A prognostic classifier that included the status of these markers led to an 85.9% classification accuracy.The analysis of the status of these specific chromosome regions by genome profiling on SNP microarrays should be a reliable tool for identifying high-risk patients in future adjuvant therapy protocols.

Establishment of novel cell lines recapitulating the genetic landscape of uveal melanoma and preclinical validation of mTOR as a therapeutic target
Uveal melanoma (UM) is the most common primary tumor of the eye in adults. There is no standard adjuvant treatment to prevent metastasis and no effective therapy in the metastatic setting. We have established a unique panel of 7 UM cell lines from either patient's tumors or patient‐derived tumor xenografts (PDXs). This panel recapitulates the molecular landscape of the disease in terms of genetic alterations and mutations. All the cell lines display GNAQ or GNA11 activating mutations, and importantly four of them display BAP1 (BRCA1 associated protein‐1) deficiency, a hallmark of aggressive disease. The mTOR pathway was shown to be activated in most of the cell lines independent of AKT signaling. mTOR inhibitor Everolimus reduced the viability of UM cell lines and significantly delayed tumor growth in 4 PDXs. Our data suggest that mTOR inhibition with Everolimus, possibly in combination with other agents, may be considered as a therapeutic option for the management of uveal melanoma.

Genome-wide profiling is a clinically relevant and affordable prognostic test in posterior uveal melanoma
This study investigated the capacity of genetic analysis of uveal melanoma samples to identify high-risk patients and discusses its clinical implications.Patients with posterior uveal melanoma were prospectively enrolled. Tumour samples were derived from enucleated globe, fine-needle aspirates or endoresection. Chromosome 3 and 8 status was determined by array comparative genomic hybridisation (array-CGH). Patients were followed after treatment to detect metastasis.Four groups were classified by array-CGH. Patients were divided into disomy 3 and normal chromosome 8 (D3/8nl), disomy 3 and 8q gain (D3/8g), monosomy 3 and normal chromosome 8 (M3/8nl) and monosomy 3 and 8 or 8q gain (M3/8g). Median follow-up was 28 months (range: 1-147 months). At the end of the study, 128 patients (33.7%) had developed metastasis and 96 patients had died. Univariate Cox proportional hazard analysis showed that factors associated with metastasis included basal tumour diameter p=0.0007, tumour thickness p=0.01, mixed/epithelioid cell type p=0.0009 and genomic data p<0.0001. High-risk profile was more strongly associated with metastasis than the other prognostic factors p<0.001. Multivariate Cox modelling analysis showed that the status of chromosomes 3 and 8 were the only two variables that independently contributed to prognosis: monosomy 3 alone p=0.001 and monosomy 3 and 8q gain p<0.0001.Array-CGH allowed identification of three prognostic groups with low, intermediate and high risk of developing metastasis. Array-CGH is a reliable and inexpensive method for uveal melanoma prognosis. This method is now currently used in France.

A high-risk retinoblastoma subtype with stemness features, dedifferentiated cone states and neuronal/ganglion cell gene expression
Retinoblastoma is the most frequent intraocular malignancy in children, originating from a maturing cone precursor in the developing retina. Little is known on the molecular basis underlying the biological and clinical behavior of this cancer. Here, using multi-omics data, we demonstrate the existence of two retinoblastoma subtypes. Subtype 1, of earlier onset, includes most of the heritable forms. It harbors few genetic alterations other than the initiating RB1 inactivation and corresponds to differentiated tumors expressing mature cone markers. By contrast, subtype 2 tumors harbor frequent recurrent genetic alterations including MYCN-amplification. They express markers of less differentiated cone together with neuronal/ganglion cell markers with marked inter- and intra-tumor heterogeneity. The cone dedifferentiation in subtype 2 is associated with stemness features including low immune and interferon response, E2F and MYC/MYCN activation and a higher propensity for metastasis. The recognition of these two subtypes, one maintaining a cone-differentiated state, and the other, more aggressive, associated with cone dedifferentiation and expression of neuronal markers, opens up important biological and clinical perspectives for retinoblastomas.

High-dose chemotherapy with carboplatin, etoposide and cyclophosphamide followed by a haematopoietic stem cell rescue in patients with high-risk retinoblastoma: a SFOP and SFGM study
<h2>Abstract</h2> This study investigates the role of high-dose chemotherapy with haematopoietic stem cell rescue as consolidation treatment in high-risk retinoblastoma (extraocular disease at diagnosis or relapse or invasion of cut end of optic nerve). 25 patients received high-dose chemotherapy including carboplatin (250mg/m<sup>2</sup>/day from day 1 to day 5 for the 6 first patients and 350mg/m<sup>2</sup>/day from day 1 to day 5 for the other patients), etoposide (350mg/m<sup>2</sup>/day from day 1 to day 5) and cyclophosphamide (1.6g/m<sup>2</sup>/day from day 2 to day 5) (CARBOPEC) followed by autologous haematopoietic stem cell rescue. 19 patients received this drug combination for chemosensitive extraocular relapse. The other 6 patients with histological high-risk factors were given this treatment as consolidation after enucleation and conventional chemotherapy. The three year disease-free survival was 67.1%. In 7 of the 9 relapsing patients, the first site of relapse was the central nervous system. All patients with central nervous system disease died except one. The main toxicity was haematological and digestive (mucositis and diarrhoea). 2 of the 13 evaluable patients had grade III and IV ototoxicity. One patient experienced an acute grade I reversible cardiotoxicity. The CARBOPEC regimen seems to be a promising therapeutic strategy in patients with high-risk retinoblastoma, especially those with bone and/or bone marrow involvement. This treatment did not improve the outcome of patients with central nervous system disease.

It is essential to identify these mutations to provide appropriate genetic counseling in retinoblastoma patients, but this represents an extremely challenging task, as the vast majority of mutations are unique and spread over the entire coding sequence. Since 2001, we have implemented RB1 testing on a routine basis as part of the clinical management of retinoblastoma. As most screening techniques do not meet the requirements for efficient RB1 testing, we have devised a semi-automated denaturing high-performance liquid chromatography (DHPLC) method for point mutation detection combined with a quantitative multiplex PCR of short fluorescent fragments (QMPSF) approach to screen for gene rearrangements. We report the results of this comprehensive screening of all exons and promoter of RB1 in 192 unrelated patients, mostly of French origin. Among 102 bilateral and/or familial cases and 90 unilateral sporadic probands, mutations were identified in 83 (81.5%) and 5 (5.5%) cases, respectively. A total of 43 mutations have not been previously reported. The mutational spectrum was found to be significantly different from previous published series, displaying a surprising amount of splice mutations and large deletions. This study demonstrates the reliability of DHPLC for RB1 analysis, but also illustrates the need for a deletion scanning approach. Finally, considering the benefits to retinoblastoma patients, RB1 testing should be widely implemented in routine healthcare because our study clearly illustrates its feasibility.

The role of chemotherapy in orbital involvement of retinoblastoma. The experience of a single institution with 33 patients
Background. Orbital involvement is a rare occurrence in retinoblastoma but still carries a bad prognosis. The aim of this study was to define more clearly the role of chemotherapy in this advanced disease. Methods. Between 1977 and 1991, 33 patients were treated at the Services de Pédiatrie at Institut Curie (Paris, France) for orbital involvement of retinoblastoma, which was isolated in 20 patients and associated with metastases in 13 patients (outside the central nervous system [CNS], 6; within the CNS, 7). Treatment included chemotherapy for 33 patients, irradiation of the orbit for 23 patients, and intrathecal chemotherapy and/or CNS irradiation in selected patients. Results. The plateau phase of the survival curve was reached at 15 months, with a survival of 34% plus or minus 8%. The disease free interval was longer when patients had no CNS disease (P < 0.05). Twenty of the 21 recurrences (95%) occurred within 1 year after diagnosis of orbital involvement. Conclusions. Intensive chemotherapy using cyclophosphamide, platinum compounds, epipodophyllotoxins, doxorubicin, and vincristine was effective in orbital involvement of retinoblastoma even with associated extra-CNS metastases. However, associated CNS disease still carries a bad prognosis, and long term follow-up is necessary to evaluate the risk of a second tumor. Cancer 1994; 74: 722-32.

Ophthalmologic and intraocular non‐Hodgkin's lymphoma: a large single centre study of initial characteristics, natural history, and prognostic factors
The aims of this study were to define the initial characteristics, natural history, and prognostic factors of patients with ophthalmologic and intraocular malignant lymphoma. All patients treated at the Institut Curie for lymphoma with ophthalmologic (orbit and/or adnexa) or intraocular involvement were retrospectively reviewed. A pathological review of all cases was performed according to the WHO classification. One hundred and forty-five patients were selected for the study. Pathological review showed 36% MALT type lymphoma, 22% lymphoplasmocytic lymphoma, and 15% diffuse large B-cell lymphoma. Ophthalmologic and ocular sites were intra-orbital in 61 cases (42%) and conjunctival in 51 cases (35%), with bilateral involvement in 10% of cases. Stage IV was found in 32% of cases, with bone marrow involvement in 12%. With a median follow-up of 90 months, the 5-year DFS and OS were 64 and 79% for low-grade NHL, and 43 and 50% for high-grade NHL. On multivariate analysis, age greater than 59 years, elevated LDH level, stage IV, high-grade histological subgroup, and presence of B-symptoms had a negative impact on OS for the overall population. In conclusion, with a median follow-up of 7.5 years, our large cohort of patients represents one of the largest published series on primary ophthalmologic and intraocular malignant lymphoma.

Analysis of ototoxicity in young children receiving carboplatin in the context of conservative management of unilateral or bilateral retinoblastoma
Abstract Background Carboplatin plays an important role in the conservative management of retinoblastoma, but is associated with risk of ototoxicity in these young children whose sensory prognosis may be also compromised by their loss of vision. This retrospective study analyzed the impact of carboplatin on hearing in the context of conservative management of children with retinoblastoma. Methods Data for 175 children treated at the Institut Curie between 1994 and 2002 were analyzed. Results Median age at diagnosis was 8 months (0–60). Carboplatin was administered on 3 days (200 mg/m 2 /day) or 5 days (160 mg/m 2 /day) with etoposide and with diode‐laser therapy at the dose of 560 mg/m 2 (chemothermotherapy). Median cumulative dose of carboplatin was 2,880 mg/m 2 (560–6,160). Ototoxicity was investigated by pure‐tone audiometry and scored by Brock's grading scale before and after treatment. The median follow‐up of hearing assessment was 5 years (1.8–11). Ototoxicity was detected in 8 children: 3 grade 1, 1 grade 2, and 2 grade 4. The two patients with grade 4 hearing‐loss required a hearing aid. Two children developed bilateral high frequency hearing‐loss, considered to be secondary to carboplatin but with less than Brock grade 1. Ototoxicity was observed for a median cumulative dose of carboplatin of 3,120 mg/m 2 (1,200–5,830). Only one child developed ototoxicity during treatment. All other cases were discovered after the last dose of carboplatin with a median interval of 3.7 years (0–7.6). No other risk factor for ototoxicity was able to account for these lesions. Conclusion Children receiving carboplatin require long‐term audiometric follow‐up. Pediatr Blood Cancer 2009;52:637–643. © 2009 Wiley‐Liss, Inc.

Pyrophosphorolysis-Activated Polymerization Detects Circulating Tumor DNA in Metastatic Uveal Melanoma
Abstract Purpose: To develop a molecular tool to detect circulating tumor–derived DNA (ctDNA) in the plasma from patients with uveal melanoma as a marker of tumor burden and monitor treatment efficacy. Experimental Design: A real-time PCR was developed on the basis of bidirectional pyrophosphorolysis-activated polymerization (bi-PAP) for the quantification of ctDNA using 3′blocked primer pairs specific for the 3 recurrent mutually exclusive mutations of Gα subunits GNAQ and GNA11. Results: Sensitivity and specificity of bi-PAP were assessed on serial dilutions of tumor DNA in normal DNA for the 3 recurrent mutations. Each assay could detect a single mutated molecule per reaction, whereas 104 copies of normal DNA were not detected. The ctDNA was readily detected in plasma of mice bearing uveal melanoma xenografts in amounts proportional to circulating human DNA. Finally, plasma was almost always found positive (20 of 21 tested patients) in a prospective analysis of patients with metastatic uveal melanoma. Conclusions: Bi-PAP assays detect and quantify ctDNA in patients with metastatic uveal melanoma. A prospective study is ongoing to assess the clinical usefulness of ctDNA level in uveal melanoma.

Ocular adverse events of molecularly targeted agents approved in solid tumours: A systematic review
When using molecularly targeted agents (MTAs), oncologists and patients face new and sometimes unexpected toxicities. Though ocular adverse events (OAEs) are not uncommon with chemotherapy, they are rarely severe or dose limiting. Ocular toxicity profile may differ with MTAs, indeed severe and dose limiting toxicities have been described with targeted therapies currently under investigation. Our study aimed to review OAEs experienced with MTAs approved in solid tumours. This review revealed that many OAEs, frequent and potentially severe, exist and concern most MTAs. The suggestion is prompt referral of patients with severe pain and/or visual impairment to the ophthalmologist since these symptoms can be associated with potentially severe OAE and need ophthalmic assessment. Oncologists must be aware of such events and their potential severity for better treatment and better diagnosis in daily practice as well as in clinical trials.

Fine Needle Aspiration Biopsy in Uveal Melanoma: Technique, Complications, and Outcomes
Purpose To report the technical aspects, complications, and outcomes concerning fine needle aspiration biopsy (FNAB) in uveal melanoma. Design Retrospective cohort study. Methods Patients with uveal melanoma who underwent transscleral or transvitreal FNAB at an ocular oncology center were retrospectively evaluated. FNAB was performed if the tumor was more than 5 mm in thickness. Array comparative genomic hybridization analysis was performed on biopsy samples with sufficient tissue. The main outcome measures were success (sample that gave a successful result for biomarker analysis) rate, complications, liver metastasis, and overall survival. Results There were 217 (114 male, 52%) consecutive study patients with a mean age of 56.7 (16–84) years. The mean follow-up period was 31 (range 3.6–61.3) months. Mean tumor thickness was 8.4 (range 5–12) mm. The overall success rate of the procedure was 169 patients (77.9%). Thirty-one patients (14.3%) experienced intravitreal hemorrhage, of whom 9 (4.1%) required vitreal surgery. There was no case of endophthalmitis, orbital dissemination, local recurrence, or rhegmatogenous retinal detachment. Thirty-two patients (14.7%) developed metastasis during the study, of whom 20 (9.2%) died. Of the 169 successful samples, 53 patients (31%) were classified as low risk, 41 (24%) as intermediate risk, and 54 (32%) as high risk. Fifteen patients (9%) did not have any detectable chromosomal abnormality and 6 (4%) could not be classified. Conclusion FNAB is a relatively safe and successful technique that can be routinely used to obtain tissue for molecular genomic analysis; such analysis helps determine the diagnosis and prognosis in uveal melanoma.

Results of a Multicenter Prospective Study on the Postoperative Treatment of Unilateral Retinoblastoma After Primary Enucleation
The objective of this prospective study was to assess overall survival and event-free survival in patients with intraocular unilateral retinoblastoma (Reese-Ellsworth group V) treated by primary enucleation with or without adjuvant therapy depending on histopathologic risk factors.Patients (n = 123) were divided into three groups on the basis of risk factors for extraocular relapse and metastasis assessed on centralized histologic examination of enucleated eyes. Group 1 (n = 70) had minimal or no choroidal involvement and/or prelaminar or no optic nerve involvement and received no adjuvant therapy. Group 2 (n = 52) had massive choroidal involvement and/or intra- or retrolaminar optic nerve involvement and/or anterior segment involvement and received four courses of adjuvant chemotherapy. Group 3 (n = 1) had invasion of the surgical margin of the optic nerve and/or microscopic extrascleral involvement and received six courses of adjuvant chemotherapy with intrathecal thiotepa, consolidation chemotherapy, and autologous stem-cell rescue. Genetic testing was also performed.Median follow-up for the 123 patients was 71 months. No disease progression, relapse, or distant metastasis occurred during follow-up. No second malignancies occurred. This requires confirmation with longer follow-up. Secondary bilateralization occurred in two patients with identified RB1 germline mutation. Adjuvant chemotherapy was well tolerated, with limited toxicity. Molecular testing found constitutional RB1 gene mutations in only nine of 100 evaluated patients.The survival rate of 100% was excellent, including 57% of patients who received no adjuvant therapy, suggesting that chemotherapy could be de-escalated in some patients, especially those with massive choroidal involvement.

The Pediatric Choroidal and Ciliary Body Melanoma Study
Purpose To collect comprehensive data on choroidal and ciliary body melanoma (CCBM) in children and to validate hypotheses regarding pediatric CCBM: children younger than 18 years, males, and those without ciliary body involvement (CBI) have more favorable survival prognosis than young adults 18 to 24 years of age, females, and those with CBI. Design Retrospective, multicenter observational study. Participants Two hundred ninety-nine patients from 24 ocular oncology centers, of whom 114 were children (median age, 15.1 years; range, 2.7–17.9 years) and 185 were young adults. Methods Data were entered through a secure website and were reviewed centrally. Survival was analyzed using Kaplan-Meier analysis and Cox proportional hazards regression. Main Outcome Measures Proportion of females, tumor-node-metastasis (TNM) stage, cell type, and melanoma-related mortality. Results Cumulative frequency of having CCBM diagnosed increased steadily by 0.8% per year of age between 5 and 10 years of age and, after a 6-year transition period, by 8.8% per year from age 17 years onward. Of children and young adults, 57% and 63% were female, respectively, which exceeded the expected 51% among young adults. Cell type, known for 35% of tumors, and TNM stage (I in 22% and 21%, II in 49% and 52%, III in 30% and 28%, respectively) were comparable for children and young adults. Melanoma-related survival was 97% and 90% at 5 years and 92% and 80% at 10 years for children compared with young adults, respectively (P = 0.013). Males tended to have a more favorable survival than females among children (100% vs. 85% at 10 years; P = 0.058). Increasing TNM stage was associated with poorer survival (stages I, II, and III: 100% vs. 86% vs. 76%, respectively; P = 0.0011). By multivariate analysis, being a young adult (adjusted hazard rate [HR], 2.57), a higher TNM stage (HR, 2.88 and 8.38 for stages II and III, respectively), and female gender (HR, 2.38) independently predicted less favorable survival. Ciliary body involvement and cell type were not associated with survival. Conclusions This study confirms that children with CCBM have a more favorable survival than young adults 18 to 25 years of age, adjusting for TNM stage and gender.

Replacement and desmoplastic histopathological growth patterns: A pilot study of prediction of outcome in patients with uveal melanoma liver metastases
Abstract Up to 50% of uveal melanomas (UM) metastasise to the liver within 10 years of diagnosis, and these almost always prove rapidly fatal. As histopathological growth patterns (HGPs) of liver metastases of the replacement and desmoplastic type, particularly from colon and breast carcinoma, may import valuable biological and prognostic information, we have studied HGP in a series of 41 UM liver metastases originating from 41 patients from the period 2006–2017. Twenty patients underwent enucleation while 21 had radiation therapy. Analysis of UM by array comparative genomic hybridisation revealed: 25 (64%) patients with high risk (monosomy3/8q gain); 13 (33%) intermediate risk (M3/8normal or disomy3/8q gain); and 1 low risk (disomy3/8normal). The principal HGP was replacement in 30 (73%) cases and desmoplastic in 11 (27%) cases. Cases with replacement demonstrated striking vascular co‐option/angiotropism. With the development of liver metastasis, only the replacement pattern, largest primary tumour diameter, and R 2 (incomplete resection) status predicted diminished overall survival (OS; p &lt; 0.041, p &lt; 0.017, p &lt; 0.047, respectively). On multivariate analysis, only HGP (hazard ratio; HR = 6.51, p = 0.008) and resection status remained significant. The genomic high‐risk variable had no prognostic value at this stage of liver metastasis. Chi‐square test showed no association of HGP with monosomy 3 or 8q gain. Eighteen of 41 (44%) patients are alive with disease and 23 (56%) patients died with follow‐up ranging from 12 to 318 months (mean: 70 months, median: 47 months). In conclusion, we report for the first time the frequency of the replacement and desmoplastic HGPs in liver UM metastases resected from living patients, and their potential important prognostic value for UM patients, as in other solid cancers. These results may potentially be utilised to develop radiological correlates and therapeutic targets for following and treating patients with UM metastases.

Etoposide and carboplatin in extraocular retinoblastoma: a study by the Société Française d'Oncologie Pédiatrique.
A phase II study of etoposide (VP-16) and carboplatin was performed in patients with extraocular retinoblastoma to evaluate the response rate with this drug combination.Twenty patients with extraocular retinoblastoma, age 9 to 120 months, were included in a cooperative multicenter phase II study of the Société Francçaise d'Oncologie Pédiatrique (SFOP). The schedule consisted of consecutive 5-day treatment with VP-16 100 mg/m2/d and carboplatin 160 mg/m2/d.The response rate for the 20 patients was 85%; there were nine complete responses and eight partial responses. Hematologic toxicity was the only serious observed toxicity and was always manageable.This combination of VP-16 and carboplatin is highly effective in extraocular retinoblastoma. The high response rate is encouraging for further evaluation of this drug combination in adjuvant chemotherapy when necessary after enucleation or in neoadjuvant chemotherapy for intraocular tumors.

Outcome of second malignancies after retinoblastoma: a retrospective analysis of 25 patients treated at the Institut Curie
Retinoblastoma is usually curable in developed countries. The morbidity and mortality of patients with hereditary retinoblastoma is still threatened by the occurrence of secondary tumours. Between 1971 and 1988, 427 patients with retinoblastoma were treated in the ophthalmologic, paediatric and radiotherapy departments of the Institut Curie. In this study, we report the clinical and therapeutic features and the outcome of 25 patients treated for a second malignant neoplasm, diagnosed between 1997 and 1999 at the Institut Curie. The median time interval between the diagnosis of retinoblastoma and SMN was 11.2 years (range 3.8–20.6 years). Histopathological diagnoses included: 12 osteosarcomas, 12 soft tissue sarcomas and, 1 malignant oligodendroglioma. The second malignant neoplasm was located inside the radiation field in 21 cases and outside in 4. Twenty three patients received pre-operative chemotherapy. Surgery was performed in 16 patients. Post-operative chemotherapy was administered in 12 patients and external beam radiotherapy was used in 2 patients. Response to treatment was evaluable in 24 patients: complete remissions were observed in 14/24, partial remissions in 2/24 and progressive disease in 8/24. Nineteen patients died. Six are still alive, with 4 in complete remission (median follow-up 8.8 years; range 5.8–13.9 years). Despite aggressive therapy, the prognosis of patients with second malignant neoplasm occurring after retinoblastoma is very poor. It is important to provide information to retinoblastoma patients regarding the risk of a second tumour as this may facilitate an early tumour detection.

Genotype–phenotype correlations in hereditary familial retinoblastoma
We studied 50 unrelated pedigrees with a family history of retinoblastoma (Rb) (165 carriers of a RB1 mutation) to delineate the spectrum of RB1 germline mutations in familial Rb and to identify genotype-phenotype correlations as well as putative modifiers. Patients were followed at Institut Curie and they were examined by an ophthalmologist, a pediatrician, and a geneticist. All cases of familial Rb were determined via genetic counseling. Clinical features included disease status, laterality, age at diagnosis, mutation type, follow-up, and disease-eye ratio (DER). To eliminate mosaic cases, first-generation carriers displaying low-penetrance (LP) Rb were excluded from the analysis. Complete penetrance was the rule for nonsense and frameshift mutations (25 families) and high penetrance was observed for large rearrangements (eight families). Promoter (two families) and missense (two families) mutations displayed heterogeneous phenotypes and LP. Variable penetrance was observed for splice abnormalities (13 families) and was explained by in/out of frame mutations or respect of functional domains. Surprisingly, two families with the LP g.45867G>T/IVS6+1G>T mutation presented data that conflicted with the data reported in previous publications, as unaffected carriers had paternally inherited mutant alleles. Moreover, RNA analyses suggested that the lack of penetrance in unaffected carriers could be explained by an increase in expression levels of the wild-type allele. This observation prompted us to define a new class "3" of LP alleles. We believe this is the first large-scale study of familial Rb with a high level of homogeneity in the clinical and genetic analysis of patients and their relatives, thereby allowing for reliable intrafamilial genotype-phenotype correlations. Our analysis suggests in some cases the influence of modifier factors probably involved in mRNA level regulation and/or pRB pathway regulation.

Conservative Treatments of Intraocular Retinoblastoma
Objective To describe the efficacy of conservative management of retinoblastoma by an association of conservative ocular therapies and chemothermotherapy. Design Phase II prospective nonrandomized trial. Participants Eighty-three children were included (115 eyes). Methods Conservative ocular therapies and chemothermotherapy (intravenous carboplatin followed by transpupillary thermotherapy to the tumor) after chemoreduction by 2 cycles of carboplatin and etoposide. Main Outcome Measures Use of external beam therapy and ocular tumor control. Results One hundred fifteen of the 147 affected eyes were eligible for conservative management. Nineteen children had unilateral lesions (22.8%), and 64 (77.1%) had bilateral lesions. Sixty-six children received neoadjuvant chemotherapy before ocular therapy, which consisted of one or a combination of several techniques: chemothermotherapy (65 children [86 eyes]) with a mean of 3 cycles per child, thermotherapy alone (22 children [24 eyes]), cryoapplication (49 children [58 eyes]), and iodine 125 brachytherapy (26 children [29 eyes]). Tumor control was achieved for 97 eyes (84%). At the end of the study, external beam radiotherapy (EBR) was necessary for a total of 9 children (11%) and 13 eyes (12%). Enucleation was necessary for a total of 23 eyes (20%), because of complications in 5 cases. Conclusions Neoadjuvant chemotherapy with 2 cycles of carboplatin and etoposide followed by ocular therapy and chemothermotherapy achieves satisfactory tumor control and permits a low need for EBR.

Preoperative staging of liver metastases from uveal melanoma by magnetic resonance imaging (MRI) and fluorodeoxyglucose-positron emission tomography (FDG-PET)
Microscopically complete (R0) resection of metastases from uveal melanoma prolongs median overall survival compared to incomplete surgery. The aim of this study was to compare the sensitivity of dynamic-enhanced magnetic resonance imaging (MRI) with fluorodeoxyglucose-positron emission tomography (FDG-PET) in the preoperative diagnosis of liver metastases from uveal melanoma.Fifteen consecutive patients (mean age: 56 years) underwent FDG-PET and liver MRI. Extrahepatic metastatic disease was excluded by whole body computed tomography and bone scintigraphy. MRI and FDG-PET were performed with a mean of 19 days (range: 1-30) before surgery. Imaging findings were compared with surgical (including intraoperative ultrasonography) and histological findings on a lesion by lesion analysis.R0 resection was performed in 12 patients. A total of 28 lesions were resected with 27 histologically proven metastases. Nine lesions were smaller than 5mm, 7 measured 5-10mm and 11 were larger than 10mm. Sensitivity and positive predictive value were 67% and 95% for MRI compared to 41% and 100% for FDG-PET. The difference between the two modalities was statistically significant (p=0.01; McNemar test). In remaining 3 patients, diffuse miliary disease (>10 capsular lesions) was discovered intraoperatively, and was suspected on preoperative MRI in 2 cases. Only one extrahepatic lesion identified by FDG-PET was falsely positive.In this preliminary study, MRI was superior to FDG-PET for staging of liver metastases from uveal melanoma. Although miliary disease was suggested by MRI in some cases, preoperative confirmation remains imperfect.

Treatment of Uveal Melanoma by Accelerated Proton Beam
Proton beam irradiation of uveal melanoma has great advantages compared to brachytherapy because of the homogenous dose delivered to the tumor and the possibility of sparing normal tissue close to the tumor. We describe the technique of proton beam therapy including the surgical technique of clip positioning, the radiotherapy delivery technique and the dose administered (60 Gy cobalt relative biological effectiveness in 4 fractions). Indications of proton beam are given and the follow-up procedure is described. An inactive residual tumor scar is observed after 2–3 years. Results are given comparing the most recent series of patients treated at the Institut Curie-Orsay proton therapy center with the data published in the literature. The metastasis rate at 10 years varies between 25 and 30%. Local control is excellent. The local recurrence rate at 10 years is usually around 5%. Secondary enucleation is performed in 10–15% of patients either due to complications or local recurrence. Complications such as retinal detachment, maculopathy, papillopathy, cataract, glaucoma, vitreous hemorrhage and dryness are described. The severest complication that usually leads to secondary enucleation is neovascular glaucoma and it is encountered after irradiation of large to extra-large tumors. The toxic tumor syndrome has recently been described. It is hypothesized that the residual tumor scar may produce proinflammatory cytokines and VEGF leading to intraocular inflammation and neovascular glaucoma. Additional treatments after proton beam such as transpupillary thermotherapy, endoresection of the tumor scar or intravitreal injections of anti-VEGF may reduce the rate of these complications.

The Small Fatal Choroidal Melanoma Study. A Survey by the European Ophthalmic Oncology Group
To determine the size at which choroidal melanomas can metastasize and to report the characteristics of small fatal choroidal melanomas (SFCM).Retrospective case series.Ten ocular oncology services submitted 45 patients with a choroidal melanoma 3 mm or less in thickness and 9 mm or less in largest basal diameter (LBD), when treated, who developed metastases.Median tumor thickness was 2.4 mm (range, 1.0-3.0 mm) and LBD 7.3 mm (range, 3.0-9.0 mm). Of 14 (31%) tumors that were first observed, 12 grew a median of 0.5 mm (range, 0.1-1.2 mm) in thickness and 1.0 mm (range, 0-3.0 mm) in LBD within a median of 7 months; 3 were initially smaller than 3 mm in LBD. Number of risk factors for growth and metastasis was 0 for 4% of the tumors; 60% were over 2 mm in thickness, 63% had subretinal fluid, 84% caused symptoms, 57% had orange pigment, and 92% were within 3 mm of the disc. Local recurrence occurred in 8 of 31 eyes (26%) treated conservatively. Median metastasis-free survival was 4.5 years (range, 0.8-15.7 years). Kaplan-Meier estimate of metastasis developing was 15% (95% confidence interval [CI], 7-26), 51% (95% CI, 36-64) and 85% (95% CI, 71-92) by 2, 5, and 10 years, respectively. By the time of analysis, 37 patients had died of metastasis after a median of 7 months.Choroidal melanomas less than 3.0 mm in LBD are highly unlikely to metastasize. Risk factors of an SFCM are similar to those for all choroidal melanomas of similar size.

Treatment of liver metastases from uveal melanoma by combined surgery—chemotherapy
Aims To investigate sporadic results demonstrating prolonged survival after surgical resection and/or intraarterial chemotherapy (IACH) for liver metastases from uveal melanoma. Methods From December 1992 to March 1997 every patient with liver metastases from uveal melanoma was enrolled in a prospective study including: (1) aggressive surgical approach removing as much liver disease as possible; (2) implantation of an intraarterial catheter; (3) intraarterial chemotherapy for 6 months. 75 patients were enrolled: 38 men, 37 women, mean age 51 years (range: 18–72), mean time from initial diagnosis of uveal melanoma to liver metastases 37 months (ranged: 1–168). Results Disseminated disease in both lobes was present in all but one patient. Macroscopically curative surgery was possible in 27.5%. Significant tumour reduction was performed in 49.3% and a simple biopsy was possible in 23.2%. Eight patients did not receive chemotherapy and died soon after. IACH included Fotemustine and/or DTIC-Platinum for 4–9 cycles. Overall median survival was 9 months; very similar to non-operated historical controls. In the 61 patients receiving complete treatment surgery plus chemotherapy, median survival improved to 10 months. When curative resection was possible, survival increased to 22 months (P<0.001). Conclusions Aggressive surgical resection, when possible, appears to be the best method of improving survival of liver metastases from uveal melanoma.

Detection of chromosome imbalances in retinoblastoma by parallel karyotype and CGH analyses
We have studied a series of 20 primary retinoblastomas by karyotypic analysis and comparative genomic hybridization (CGH), to perform an exhaustive evaluation of chromosome imbalances in this tumor. In addition, 4 tumors were studied by CGH only. On the whole, CGH results were largely in agreement with those of karyotypic analysis and with known cytogenetic data. The most frequent imbalances were +6p (13/24 cases), +1q (12/24), −16/−16q (11/24), and +2p (9/24). Recurrent high-level amplifications were observed in 2p23–25 and 1q21. Amplification of 2p23–25, present in 4 cases among which 3 showed double-minute chromosomes, was related to MYCN amplification, as demonstrated by FISH and PCR. No evident correlation was found in this small series between any of the imbalances identified and either the differentiation or the histoprognostic risk.

Role of chemotherapy alone or in combination with hyperthermia in the primary treatment of intraocular retinoblastoma: preliminary results
The efficacy of the etoposide-carboplatin combination in extraocular retinoblastoma is well known. This drug combination is therefore used in intraocular retinoblastoma, as primary reduction chemotherapy, before local treatment. The use of carboplatin in combination with diode laser hyperthermia as local treatment (thermochemotherapy) has been recently described as a conservative approach avoiding external beam radiotherapy in posterior pole tumours.All patients were reviewed, who were treated for retinoblastoma at the Institut Curie between June 1994 and October 1995, in whom treatment included either reduction chemotherapy or thermochemotherapy or both modalities successively. 23 patients presenting with unilateral (three) or bilateral (20) intraocular retinoblastoma received neoadjuvant chemotherapy consisting of two courses of etoposide 150 mg/m2/day and carboplatin 200 mg/m2/day for 3 days. 15 patients (17 eyes), eight of whom had already received neoadjuvant chemotherapy, were treated by thermochemotherapy.Neoadjuvant chemotherapy: overall, seven eyes in seven patients could be treated conservatively, avoiding external beam irradiation, with a median follow up of 14 months. Thermochemotherapy: external beam irradiation was avoided for 14 of the 17 eyes treated.Integration of neoadjuvant chemotherapy and combined treatment with carboplatin and diode laser, into the therapeutic armamentarium for retinoblastoma allows use of more aggressive treatments such as enucleation and external beam radiation.

Osteosarcoma following retinoblastoma: Age at onset and latency period
In order to assess the role of genetic predisposition in the induction of radiation-induced tumors, we performed statistical analysis on data from the literature and from our own Institute with regard to the age at onset and the latency period of osteosarcoma as the second primary tumor for retinoblastoma with or without subsequent radiotherapy. In retinoblastoma survivors who subsequently developed osteosarcoma, the age at onset of retinoblastoma was young (average of 12 months) in both unilateral and bilateral forms. This suggests that all or almost all of the patients were genetically predisposed by a mutation of one allele of the RB1 gene. For retinoblastoma patients, osteosarcomas occurred 1.2 years earlier inside than outside the radiation field. The latency period between radiotherapy and osteosarcoma onset was 1.3 years shorter inside than outside the radiation field. Interestingly, a bimodal distribution of latency periods was observed for osteosarcomas arising inside, but not outside the radiation field: 40% occurred after a short latency, while the latency of the remaining 60% was comparable to that of osteosarcoma occurring outside the radiation field. This suggests that different mechanisms may be involved in radiocarcinogenesis. A radiation-induced mutation of the second RB1 allele may be the cause of osteosarcomas occurring after a short delay, while other genes may be affected in those occurring after a longer delay.

Dysmorphic phenotype and neurological impairment in 22 retinoblastoma patients with constitutional cytogenetic 13q deletion
We describe the facial dysmorphic phenotype and the neurological development of a series of 22 retinoblastoma patients sharing a cytogenetically detectable 13q deletion in a retrospective and longitudinal study. In most of the cases, high‐resolution banding analysis, morphological analysis, and assessment for neurodevelopmental outcome, as well for organ malformations, were performed. Chromosomal rearrangement involving the RB1 gene included 20 13q interstitial deletions (including 16 de novo deletions) and two de novo translocations. The most prominent dysmorphic abnormalities were anteverted ear lobes (90%), a high and broad forehead (85%), and a prominent philtrum (65%). This phenotype was associated with severe mental retardation and/or motor impairment at age 2 years in 69% of patients and correlated with the size and the location of the 13q deletion. The survival rate of our series (91%) was not different from that usually seen in retinoblastoma patients.

Neoadjuvant chemotherapy for extensive unilateral retinoblastoma
<b>Aim:</b> The role of neoadjuvant chemotherapy was studied when first line enucleation cannot be safely performed in unilateral extensive retinoblastoma (major buphthalmia or radiologically detectable optic nerve involvement). <b>Methods:</b> Six patients, referred for unilateral retinoblastoma, presented with major buphthalmia (two) or optic nerve invasion (four): they were treated by neoadjuvant chemotherapy using etoposide and carboplatin. <b>Results:</b> Good tumour response was observed in the two patients with buphthalmia and in three of four cases with optic nerve involvement. Meningeal progressive disease was observed in the last patient. The five patients without disease progression were then operated on: anterior enucleation in the patients with buphthalmia and enucleation via a double neurosurgical and ophthalmological approach with prechiasmatic optic nerve section in the other three cases. Postoperative chemotherapy was performed in these five patients. Local radiotherapy to the chiasmatic region and posterior part of the optic canal was necessary in only one patient. The non-operated patient died with disease progression 6 months after the diagnosis. The other five patients are alive with a follow up of 12, 15, 21, 36, and 40 months after stopping treatment. <b>Conclusion:</b> Neoadjuvant chemotherapy can be useful in extensive unilateral retinoblastoma with buphthalmia and/or radiological optic nerve invasion at diagnosis.

Efficacy of Proton Therapy in Circumscribed Choroidal Hemangiomas Associated with Serous Retinal Detachment
The purpose of the study is to evaluate the efficacy and safety of proton therapy in complicated circumscribed choroidal hemangiomas.The study design was a retrospective review.Studied were 13 patients (13 eyes) who had circumscribed choroidal hemangioma associated with serous retinal detachment. Of these, four eyes previously underwent laser unsuccessfully.Proton therapy including a total dose of 30 Cobalt-Gray-Equivalent was administered to each eye.Patients were controlled for initial and final best-corrected visual acuity, slit-lamp examination, intraocular pressure, fundus examination, fluorescein angiography, and tumor thickness on B-scan ultrasonography.The mean follow-up period was 26 months (range, 9-48 months). Retinal reattachment was obtained in all cases after a mean period of 52 days. The tumor height decreased in all cases. Visual acuity improved to two lines or more in eight eyes (62%) and reached 20/200 or more in nine eyes (69%). No radiation complication was detected during follow-up.Proton radiation seems to be effective and safe in the management of choroidal hemangioma associated with serous retinal detachment. It may be useful when photocoagulation can not be performed.

A deep intronic mutation in the RB1 gene leads to intronic sequence exonisation
Familial forms of retinoblastoma, an embryonic neoplasm of retinal origin, are caused by constitutional mutations of the RB1 gene. In this paper, we describe a family with retinoblastoma affecting two brothers with no previous family history of cancer. Complete RB1 mutational screening including point mutation and large rearrangement screening failed to demonstrate any mutation. The whole coding sequence was therefore investigated at the cDNA level, demonstrating a 103 bp intronic insertion between exons 23 and 24, leading to subsequent frameshift and premature termination of translation. This intronic exonisation was caused by a deep intronic mutation in intron 23 generating a cryptic 3' splice site. This is the first report of a deep intronic mutation in RB1 and is a proof of concept that some undetected RB1 mutations should be investigated at the cDNA level, particularly in hereditary forms of retinoblastoma.

LONG-TERM RESULTS OF LOW-DOSE PROTON BEAM THERAPY FOR CIRCUMSCRIBED CHOROIDAL HEMANGIOMAS
In Brief Purpose: To evaluate the long-term efficacy and outcome of low-dose proton beam irradiation in the treatment of symptomatic circumscribed choroidal hemangioma. Patients and Methods: Retrospective review of 71 patients with symptomatic circumscribed choroidal hemangiomas treated by proton beam irradiation between September 1994 and October 2002 using a total dose of 20 Cobalt Gray Equivalent. Results: The median follow-up was 52 months (8–133 months). Retinal reattachment was obtained in all cases. Tumor thickness decreased in all cases and a completely flat scar was obtained in 65 patients (91.5%). Visual acuity was improved by two lines or more in 37 of the 71 patients (52%), and in 30 of the 40 patients (75%) treated within 6 months after onset of the first symptoms. The main radiation complications detected during follow-up were cataract (28%) and radiation-induced maculopathy (8%). None of the 71 patients developed eyelid sequelae or neovascular glaucoma. Conclusion: Proton beam irradiation with a total dose of 20 Cobalt Gray Equivalent appears to be a valid treatment for circumscribed choroidal hemangiomas, inducing definitive retinal reattachment and decreasing tumor thickness. However, delayed radiation-induced maculopathy may occur. A successful functional outcome is dependent on a short interval between onset of the first symptoms and initiation of therapy.

Comparative Transcriptome and Network Biology Analyses Demonstrate Antiproliferative and Hyperapoptotic Phenotypes in Human Keratoconus Corneas
Purpose.: To decipher the biological pathways involved in keratoconus pathophysiology by determining the patterns of differential gene expression between keratoconus and control corneas. Methods.: RNA was extracted from surgically removed corneas of 10 keratoconus patients and from normal corneas of 10 control patients who had undergone enucleation of an eye for ocular melanoma. Several hundred thousand RNA transcripts were assessed using exon microarrays. Statistical comparison and identification of differentially regulated and differentially spliced RNA transcripts was performed by comparing keratoconus cases and controls. In addition, relevant biological pathways were identified by information extraction using network biology. Results.: Eighty-seven genes showed significant differences in expression levels. Among these, 69 were downregulated in keratoconus patients, particularly partners of the transcription factor AP-1. The 18 overexpressed genes include mucins, keratins, and genes involved in fibroblast proliferation. In addition, 36 genes were shown to be differentially spliced, including 9 among those that were differentially expressed. Network biology and analysis using Gene Ontology descriptors suggest that many members of both groups belong to pathways of apoptosis and regulation of the balance between cellular differentiation and proliferation. Conclusions.: This work constitutes the first genome-wide transcriptome analysis of keratoconus patient corneas that include all currently known genes and exons. Differential expression suggests that mechanisms of cell loss resulting from antiproliferative and hyperapoptotic phenotypes may be responsible for the pathogenesis of keratoconus. Array information, experimental design, raw intensities, and processed log2 ratios were deposited at the European Bioinformatic Institute's ArrayExpress database (http://www.ebi.ac.uk/arrayexpress/). The accession number is E-MEXP-2777.

Patient‐derived xenografts recapitulate molecular features of human uveal melanomas
We have previously developed a new method for the development and maintenance of uveal melanoma (UM) xenografts in immunodeficient mice. Here, we compare the genetic profiles of the primary tumors to their corresponding xenografts that have been passaged over time. The study included sixteen primary UMs and corresponding xenografts at very early (P1), early (P4), and late (P9) in vivo passages. The tumors were analyzed for mutation status of GNAQ, GNA11, GNAS, GNA15, BAP1, and BRAF, chromosomal copy number alterations using Affymetrix GeneChip(®) Genome-Wide Human SNP6.0 arrays, gene expression profiles using GeneChip(®) Human Exon 1.0 ST arrays, BAP1 mRNA and protein expression, and MAPK pathway status using Reverse Phase Protein Arrays (RPPA). The UM xenografts accurately recapitulated the genetic features of primary human UMs and they exhibited genetic stability over the course of their in vivo maintenance. Our technique for establishing and maintaining primary UMs as xenograft tumors in immunodeficient mice exhibit a high degree of genetic conservation between the primary tumors and the xenograft tumors over multiple passages in vivo. These models therefore constitute valuable preclinical tool for drug screening in UM.

Targeting Bcl-2/Bcl-XL Induces Antitumor Activity in Uveal Melanoma Patient-Derived Xenografts
Purpose Uveal melanoma (UM) is associated with a high risk of metastases and lack of efficient therapies. Reduced capacity for apoptosis induction by chemotherapies is one obstacle to efficient treatments. Human UM is characterized by high expression of the anti-apoptotic protein Bcl-2. Consequently, regulators of apoptosis such as Bcl-2 family inhibitors may constitute an attractive approach to UM therapeutics. In this aim, we have investigated the efficacy of the Bcl-2/Bcl-XL inhibitor S44563 on 4 UM Patient-Derived Xenografts (PDXs) and derived-cell lines. Experimental Design Four well characterized UM PDXs were used for in vivo experiments. S44563 was administered alone or combined with fotemustine either concomitantly or after the alkylating agent. Bcl-2, Bcl-XL, and Mcl-1 expressions after S44563 administration were evaluated by immunohistochemistry (IHC). Results S44563 administered alone by at 50 and 100 mg/kg i.p. induced a significant tumour growth inhibition in only one xenograft model with a clear dose effect. However, when S44563 was concomitantly administered with fotemustine, we observed a synergistic activity in 3 out of the 4 tested models. In addition, S44563 administered after fotemustine induced a tumour growth delay in 2 out of 3 tested xenografts. Finally, IHC analyses showed that Bcl-2, Bcl-XL, and Mcl-1 expression were not modified after S44563 administration. Conclusion The novel anti-apoptotic experimental compound S44563, despite a relative low efficacy when administered alone, increased the efficacy of fotemustine in either concomitant or sequential combinations or indeed subsequent to fotemustine. These data support further exploration of potential therapeutic effect of Bcl-2/Bcl-xl inhibition in human UM.

Validation of a Prognostic Staging for Metastatic Uveal Melanoma: A Collaborative Study of the European Ophthalmic Oncology Group
Purpose To validate a staging system for metastatic uveal melanoma that will facilitate planning, reporting, and interpreting the results of clinical trials. Design Reliability and validity study. Methods The performance index, the largest diameter of the largest metastasis and alkaline phosphatase level at the time of diagnosis of metastases, and overall survival of 249 patients from 7 ocular oncology centers who died of dissemination were analyzed. Predicted median survival time calculated according to the Helsinki University Hospital Working Formulation was used to assign patients to stages IVa, IVb, and IVc, which correspond to predicted survival times of ≥12, <12-6, and <6 months, respectively. The predictions were compared against observed survival. Results The 3 variables used to assign stage were independent predictors of survival in the validation dataset. Of the 249 patients, 110 (44%), 109 (44%), and 30 (12%) were classified to Working Formulation stages IVa, IVb, and IVc, respectively. Corresponding median observed survival times were 18.6, 10.7, and 4.6 months and worsened by increasing stage (P < .001). Of 201 patients managed without surgical resection of metastases, 83 (41%), 89 (44%), and 29 (15%) were classified to stages IVa, IVb, and IVc, respectively, and their median observed survival times were 17.2, 10.0, and 4.6 months (P < .001). Survival of 47 patients who underwent resection did not differ by working formulation stage (P = .69). Conclusions This multicenter study confirms that the Working Formulation is a reliable and valid, repeatable system for dividing metastatic uveal melanoma into distinct prognostic subgroups, especially for stage-specific reporting of survival in prospective clinical trials.

Chemothermotherapy in the management of retinoblastoma1 1None of the authors have any financial interests in the drugs or devices described in this article.
To evaluate the results of chemothermotherapy for the treatment of retinoblastoma.Non-comparative interventional case series.Fifty-one children (65 eyes and 103 tumors) were treated with chemothermotherapy in a single institution from January 1995 to May 1998.Chemothermotherapy consists of a combination of transpupillary thermotherapy delivered shortly after intravenous (IV) injection of carboplatin (560 mg/m(2)). Each tumor is treated separately with a diode laser using a microscope. Laser intensity, spot size, and duration are adapted to the size of each tumor and to the clinical response. After 8 days, thermotherapy alone is repeated. This cycle is performed from one to six times, every 28 days. The treatment data and outcome are analyzed separately.Assessment of local tumor control.One hundred three tumors were treated in 65 eyes of 51 children. Age at diagnosis was 0 to 60 months (median, 7 months). Median tumor diameter at the time of treatment was 3.5 mm (range, 1.5-12 mm). Laser modalities were as follows: median intensity, 450 mW (range, 150-1000 mW); median spot size, 1.2 mm (range, 0.3-2.0 mm); and median number of cycles required to obtain tumor control, three. Tumor regression was obtained for 99 tumors (96.1%) after a median follow-up of 30 months (17-61 months). Seven tumors relapsed after initial control (6.8%). Salvage treatment (external beam radiation, iodine plaques, or enucleation) was necessary for a total of 11 tumors (10.7%). The only risk factor for relapse was the initial diameter of the lesion greater than 3.5 mm, whereas the other tumor characteristics or treatment variables were not significantly correlated with relapse. Ninety-seven percent of treated eyes were able to be preserved, and 92% of cases were treated without external beam radiation.Chemothermotherapy is an effective technique to treat small- to medium-sized retinoblastomas in children, avoiding external beam irradiation.

Germlinebrca2 sequence variants in patients with ocular melanoma
On the basis, chiefly, of anecdotal reports of cases of ocular melanoma (OM) occurring in families with inherited susceptibility to breast cancer due to brca2 germline mutations, we examined the frequency of brca2 alterations in a series of 62 ocular melanoma cases. These cases were preferentially selected on the basis of reported family history of breast or ovarian cancer, or OM, although the series also included a randomly selected set of cases without family history of cancer. A total of 7 germline alterations were found, of which 3 were likely to be associated with disease. While all 3 deleterious mutations were found in patients who also had a personal history of breast cancer, only 1 of the 3 families had a family history of breast/ovarian cancer or OM. Although germline brca2 mutations may account for a small proportion of all OM cases, there may be additional loci that contribute to familial aggregation of OM and to the familial association between OM and breast cancer.

Multiplex PCR/liquid chromatography assay for detection of gene rearrangements: application to RB1 gene
Screening for large gene rearrangements is established as an important part of molecular medicine but is also challenging. A variety of robust methods can detect whole-gene deletions, but will fail to detect more subtle rearrangements that may involve a single exon. In this paper, we describe a new, versatile and robust method to assess exon copy number, called multiplex PCR/liquid chromatography assay (MP/LC). Multiple exons are amplified using unlabeled primers, then separated by ion-pair reversed-phase high-performance liquid chromatography (IP-RP-HPLC), and quantitated by fluorescent detection using a post-column intercalation dye. The relative peak intensities for each target directly reflect exon copy number. This novel technique was used to screen a panel of 121 unrelated retinoblastoma patients who were tested previously using a reference strategy. MP/LC correctly scored all deletions and demonstrated a previously undetected RB1 duplication, the first to be described. MP/LC appears to be an easy, versatile, and cost-effective method, which is particularly relevant to denaturing HPLC (DHPLC) users since it broadens the spectrum of available applications on a DHPLC system.

In vitro phototoxicity of glycoconjugated porphyrins and chlorins in colorectal adenocarcinoma (HT29) and retinoblastoma (Y79) cell lines
Retinoblastoma is the most common malignant intraocular tumor in children. The current treatment gives a good vital prognostic but there are several drawbacks to the arsenal of “classical antitumoral” therapies. Photodynamic therapy (PDT) could be an exciting non-toxic and non-mutagenic alternative protocol. In this paper, we report about the screening of the in vitro photocytotoxicity of hydrophenylporphyrins and chlorins and their glycoconjugated derivatives in a human retinoblastoma cell line (Y79) and for comparison in a colorectal adenocarcinoma cell line (HT29). Despite lower photodynamic activity than that observed for hydroxylated photosensitizers, in particular Foscan® glycoconjugated derivatives display phototoxicity (IC50 2.4–0.05 μM ±10%) against Y79 cells with examples of significant intrinsic cytotoxicity. Amongst them the triglucosyl porphyrin 10 is highly photocytotoxic (IC50 0.9 μM ±10%) but is fully devoid of cytotoxicity (IC50 > 15 μM). The photoactivity is highly modulated by the presence of a diethyleneglycol spacer between the chromophore and the glycoside (compounds 14–17, IC50 0.5, 0.6, 0.05 and 0.35 μM ±10%) and by the anomeric configuration of the sugar (compound 15 and 17, IC50 0.6 and 0.05 μM ±10% respectively). One of the main problems for the use of Foscan® is its poor solubility which might be improved by glycoconjugation. Moreover Foscan has been shown to induce necrosis after PDT leading to a possible ulceration of surrounding tissues unsuitable for a conservative treatment. A preferential mitochondrial subcellular localization which has been previously reported for some glycoconjugated photosensitizers could enhance the contribution of apoptosis process. Tri-α-O-galactosyl porphyrin 16 is a better candidate than Foscan® for a clinical application of PDT for a conservative therapy of retinoblastoma.

The spectrum of ABO hemolytic disease of the newborn infant
A series of 1,704 infants of blood group O mothers have been studied to determine the relation between the degree of red cell sensitization and the cord hemoglobin and bilirubin concentrations. The infants with blood group A or B had significantly higher cord bilirubin and lower cord hemoglobin concentrations than the group O babies. Those infants whose red cells had the greatest evidence of sensitization had the highest bilirubin and lowest hemoglobin levels. The infants in whom no antibody was demonstrable on the red cells or in the red cell eluate also had significantly higher cord bilirubin and lower cord hemoglobin levels than the ABO compatible group; it is suggested that these infants had sufficient erythrocyte sensitization to produce mild hemolysis. ABO incompatibility represents a spectrum of hemolytic disease extending from those in which there is little laboratory evidence of erythrocyte sensitization, but evidence of hemolysis, to severe hemolytic disease in which erythrocyte sensitization is usually easily demonstrable.

Trilateral retinoblastoma: neuroimaging characteristics and value of routine brain screening on admission
Trilateral retinoblastoma (TRb) is a rare disease associating intraocular retinoblastoma with intracranial primitive neuroectodermal tumor. Treatment is difficult and prognosis is poor. This multicenter study evaluates clinical findings and MR imaging characteristics of associated intracranial tumors in Rb patients. Clinical data of 17 patients (16 TRb and 1 quadrilateral Rb patients) included time intervals between Rb and TRb diagnosis and presence of baseline brain-imaging (BBI). Two reviewers reviewed all images individually and one reviewer per center evaluated their images. Consensus was reached during a joint scoring session. Studies were reviewed for tumor location, size and imaging characteristics (signal intensity (SI) on T1- and T2-weighted images, enhancement pattern and cystic appearance). Of 18 intracranial tumors, 78 % were located in the pineal gland and 22 % suprasellar. All tumors showed well-defined borders with mostly heterogenous enhancement (72 %) and isointense SI on T1- (78 %) and T2-weighted images (72 %) compared to gray matter. The majority of pineal TRbs showed a cystic component (57 %). TRb detected synchronously with the intraocular tumors on BBI (n = 7) were significantly smaller (P = 0.02), and mainly asymptomatic than TRb detected later on (n = 10). Overall, 5-year-survival of TRb patients detected on BBI was 67 % (95 % CI 29-100 %) compared to 11 % (95 % CI 0-32 %) for the group with delayed diagnosis. TRb mainly develops in the pineal gland and frequently presents with a cystic appearance that could be misinterpreted as benign pineal cysts. Routine BBI in all newly diagnosed Rb patients can detect TRb at a subclinical stage.

Second cranio-facial malignancies in hereditary retinoblastoma survivors previously treated with radiation therapy: Clinic and radiologic characteristics and survival outcomes
Hereditary retinoblastoma survivors have an increased risk for cranio-facial second primary tumours (SPT), especially after treatment with external beam radiotherapy (EBRT). This multicentre study evaluates the clinical and imaging characteristics and outcomes of cranio-facial SPTs in irradiated retinoblastoma survivors.Clinical and radiological data of 42 hereditary retinoblastoma patients with 44 second and third malignancies were reviewed. Radiological data included anatomic location and computed tomography (CT) and magnetic resonance (MR) characteristics. Cox regression and likelihood ratio chi-square test were used to evaluate differences in patients' survival rates.Cranio-facial SPTs were diagnosed at a median age of 13 years. Histological types included osteosarcomas (43%), rhabdomyosarcomas (20%) (57% embryonal, 43% alveolar) and a variety of other types of SPT (37%). Predilection sites were: temporal fossa (39%), ethmoid sinus (23%), orbit (18%), maxillary sinus (16%) and intracranial dura mater (4%). Most of the osteosarcomas (78%) and rhabdomyosarcomas (80%) occurred in patients treated with EBRT in the first year-of-life. Treatment of SPTs with a microscopically complete surgical resection led to a significantly better 5-year overall survival (OS) (P=0.017) and event-free survival (EFS) (P=0.012) compared to patients treated without surgery or incomplete resection (OS: 83% versus 52%; EFS: 80% versus 47%).Osteosarcomas and rhabdomyosarcomas are the most common cranio-facial SPTs in irradiated hereditary retinoblastoma survivors, which develop in specific locations and occur predominantly in patients irradiated in their first year-of-life. Microscopically complete surgical resection of SPTs is a major prognostic factor, suggesting the potential benefit of early detection by imaging.

CHOROIDAL MELANOMA
To evaluate the efficacy of endoresection after proton beam radiotherapy to prevent neovascular glaucoma (NVG) in patients treated for choroidal melanoma.From a series of 4,867 patients treated for choroidal melanoma were prospectively recorded in the database (Macro Infermed 3.075). One hundred and seventy-one patients presenting a tumor diameter >10 mm and thickness >5 mm treated with proton beam (PB) radiotherapy were selected. One group of 63 patients was treated with PB therapy followed by endoresection (PE) of the scar. This group was compared with 2 historical matched controlled groups: 57 patients treated with PB therapy alone (P) and 51 patients treated with PB therapy followed by transpupillary thermotherapy of the scar (PTTT). Main outcome measures are as follows: age, gender, tumor diameter, tumor thickness, pre- and posttreatment visual acuity, NVG rate, secondary enucleation rate, and 5-year survival. Statistical analysis was performed using R version 2.5.1 software.Correlations between the 3 groups were P = 0.29 for age, P = 4.7×10 for tumor diameter, and P = 6.44×10 for tumor thickness. Comparison between the 3 groups showed that 2-year survival without secondary enucleation was 96.2% for PE, 88.8% for P, and 98% for PTTT (P = 0.203) (95% confidence interval). Two-year survival without NVG (95% confidence interval) was 92.7% (85.1-1.00) for PE, 54.6% for P, and 62.1% for PTTT (P = 0.0001). The difference between the endoresection (PE) group and the PB radiotherapy (P) and PB radiotherapy + TTT (PTTT) groups in terms of reduction of the NVG rate was statistically significant. Relative risk of developing NVG was calculated with the P group as reference, relative risk = 1. The relative risk of the PTTT group was 0.79 (20% reduction of the risk), and the relative risk of the PE group was 0.18 (82% reduction of the risk of developing NVG).This study shows that endoresection of the necrotic scar after PB radiotherapy reduces the risk of NVG and secondary enucleation for selected choroidal melanoma patients.

The survival gene MED4 explains low penetrance retinoblastoma in patients with large RB1 deletion
Retinoblastoma is a non-hereditary as well as an inherited pediatric tumor of the developing retina resulting from the inactivation of both copies of the RB1 tumor suppressor gene. Familial retinoblastoma is a highly penetrant genetic disease that usually develops by carrying germline mutations that inactivate one allele of the RB1 gene, leading to multiple retinoblastomas. However, large and complete germline RB1 deletions are associated with low or no tumor risk for reasons that remain unknown. In this study, we define a minimal genomic region associated with this low penetrance. This region encompasses few genes including MED4 a subunit of the mediator complex. We further show that retinoblastoma RB1 -/- cells cannot survive in the absence of MED4, both in vitro and in orthotopic xenograft models in vivo, therefore identifying MED4 as a survival gene in retinoblastoma. We propose that the contiguous loss of the adjacent retinoblastoma gene, MED4, explains the low penetrance in patients with large deletions that include both RB1 and MED4. Our findings also point to another synthetic lethal target in tumors with inactivated RB1 and highlight the importance of collateral damage in carcinogenesis.

Correlation between RB1germline mutations and second primary malignancies in hereditary retinoblastoma patients treated with external beam radiotherapy
Retinoblastoma (Rb) results from biallelic inactivation of the RB1 gene. Hereditary Rb patients i. e germline carriers of a RB1 mutation also have a risk of developing subsequent malignant neoplasms (SMN) such as osteosarcomas. This SMN risk is maximized by external beam radiotherapy treatments (EBRT), which is why these treatments are now avoided. Nevertheless, EBRT is still a matter of great concern, as EBRT-treated patients are in their adulthood and SMNs remain the major cause of death for patients. To decipher the relationship between RB1 genotype and SMN development in EBRT treated patients, we conducted a retrospective study in a cohort of 160 irradiated hereditary Rbs with fully resolved RB1 mutational status. Median follow-up was 22 years [1-51] and median age of patients was 27 years old [7-53]. Among these 160 Rb patients, 120 did not develop any SMN (75%) and 40 developed SMNs (25%). The age at which EBRT is given (i.e. before or after the age of 12 months) was not correlated to SMN development (p = 0.6). We didn't find any difference in RB1 mutation type between patients with or without SMN, neither could we detect any linkage between mutation type and SMN location, SMN type and age at diagnosis. Interestingly, among 13 carriers of a RB1 low penetrance mutation, 3 of them developed sarcomas, a rare tumor that cannot be attributed to the general population. Our study cannot explain why a RB1 mutation leads or not to a SMN but demonstrated that EBRT patients with a low penetrance mutation remain at risk of SMN and should be cautiously monitored.

125I plaque brachytherapy for anterior uveal melanomas
To describe the results of 125I plaque brachytherapy of uveal melanomas anterior to the equator in terms of local control and the associated complications while trying to identify their risk factors (patients' demographic data, ocular, and tumour characteristics).Retrospective analysis of a series of patients treated by 125I between 1990 and 2000 in a single institution. The main outcome measures are evaluation of local tumour control and complications associated with 125I plaque brachytherapy of these melanomas.During the study period, 136 patients were treated for an anterior tumour. The median follow-up was 62 months. The overall 5-year survival rate was 88.3%, the 5-year metastasis rate was 4% and the local recurrence rate was 1.5%. The mean final visual acuity was 20/40. The ocular complications most frequently observed at 5 years were cataract (50.3%), maculopathy (18.3%), intraocular inflammation (19.3%), and glaucoma (10.6%). Optic neuropathy, retinal detachment, keratitis, and intravitreous haemorrhage were also described. Risk factors for worse survival were age greater than 65 years and initial tumour thickness greater than 4 mm. Risk factors for the development of cataract were age more than 65 years old, male gender, and tumour diameter of more than 10 mm. Risk factors for intraocular inflammation were tumour thickness of more than 4 mm and invasion of the ciliary body.The use of 125I plaque brachytherapy to treat melanomas situated anterior to the equator allows good local and systemic control with a low rate of macular and optic disc complications. The most frequent complication was cataract formation.

Individuals with presumably hereditary uveal melanoma do not harbour germline mutations in the coding regions of either the P16INK4A, P14ARF or cdk4 genes
In familial cutaneous malignant melanoma (CMM), disruption of the retinoblastoma (pRB) pathway frequently occurs through inactivating mutations in the p16 (p16INK4A/CDKN2A/MTS1) gene or activating mutations in the G1-specific cyclin dependent kinase 4 gene (CDK4). Uveal malignant melanoma (UMM) also occurs in a familial setting, or sometimes in association with familial or sporadic CMM. Molecular studies of sporadic UMM have revealed somatic deletions covering the INK4A-ARF locus (encoding P16INK4Aand P14ARF) in a large proportion of tumours. We hypothesized that germline mutations in the p16INK4A, p14ARFor CDK4 genes might contribute to some cases of familial UMM, or to some cases of UMM associated with another melanoma. Out of 155 patients treated at the Institut Curie for UMM between 1994 and 1997, and interviewed about their personal and familial history of melanoma, we identified seven patients with a relative affected with UMM (n = 6) or CMM (n = 1), and two patients who have had, in addition to UMM, a personal history of second melanoma, UMM (n = 1), or CMM (n = 1). We screened by polymerase chain reaction single-strand conformation polymorphism the entire coding sequence of the INK4A-ARF locus (exon 1α from p16INK4A, exon 1β from p14ARF, and exons 2 and 3, common to both genes), as well as the exons 2, 5 and 8 of the CDK4 gene, coding for the functional domains involved in p16 and/or cyclin D1 binding. A previously reported polymorphism in exon 3 of the INK4A-ARF locus was found in one patient affected with bilateral UMM, but no germline mutations were detected, either in the p16INK4A, p14ARFor CDK4 genes. Our data support the involvement of other genes in predisposition to uveal melanoma. © 2000 Cancer Research Campaign

Retinoblastoma: Update on Current Management
Retinoblastoma is a rare cancer in children, where in less than a century of dire mortality there has been a cure in industrialized countries. Unfortunately, mortality remains high in emerging countries. The evolution of treatment makes it possible to go further by preserving the eyeball but this must not be done at the cost of the reappearance of metastases. Herein we outline the evolution of treatment from the beginning of the 20th century until the last recent evolutions, trying to imagine what could be the future treatments. In this pathology, the ophthalmologist is a doctor who must cure his patient and enucleation is considered a failure. This situation should not lead to shizophrenic situations where to keep an eye one would take risks with the life of the child. New international classifications, international prospective multicentric studies, and the search for blood biomarkers that can predict the risk of micrometastases could allow for better stratification of patients.

Optical Coherence Tomography Angiography of Macular Features After Proton Beam Radiotherapy for Small Choroidal Melanoma
Purpose To describe the macular features of patients treated with proton beam therapy for choroidal melanoma (CM), using optical coherence tomography angiography (OCTA). Design Retrospective case-control study. Methods This study included patients treated with proton beam radiotherapy (PBR) for a small CM. Only patients who had received 100% of the dose of 60 Gy external beam radiation to the macular area were included in the analysis. All the patients had undergone a full ophthalmologic examination, including visual acuity, optical coherence tomography B-scan, and OCTA. Qualitative and quantitative vascular features of the retinal plexus and the choriocapillaris were analyzed on OCTA and compared with those in healthy subjects matched on age and sex. Results Thirty-seven patients had undergone an OCTA after PBR for a small CM. Seventeen patients (9 men and 8 women) were included. The mean age of the patients was 56.6 years (range, 28-86). At presentation, the mean tumor thickness was 3.39 mm (range, 1.3-7.0 mm). The mean follow-up duration was 35.8 months (range, 11-72 months). Thirteen patients (76.5%) had a clinical radiation maculopathy; 8 patients (47.1%) had macular cysts on OCT-B scan. All patients (100%) had abnormalities on OCTA. Some “signal void” spots were detected at the level of the choriocapillaris in 15 patients (88.2%). The mean vascular density (regarding the full retina) was significantly lower in the patients treated with PBR than in healthy subjects (P < .0001). Conclusion Patients treated with PBR for CM (with 100% of the dose given to the macula) present major changes at both plexuses but also a vascular rarefaction of the choriocapillaris.

Thirteen patients (76.5%) had a clinical radiation maculopathy; 8 patients (47.1%) had macular cysts on OCT-B scan. All patients (100%) had abnormalities on OCTA. Some “signal void” spots were detected at the level of the choriocapillaris in 15 patients (88.2%). The mean vascular density (regarding the full retina) was significantly lower in the patients treated with PBR than in healthy subjects (P < .0001). Patients treated with PBR for CM (with 100% of the dose given to the macula) present major changes at both plexuses but also a vascular rarefaction of the choriocapillaris.

Treatment of retinoblastoma in Sub‐Saharan Africa: Experience of the paediatric oncology unit at Gabriel Toure Teaching Hospital and the Institute of African Tropical Ophthalmology, Bamako, Mali
Abstract Background Retinoblastoma (Rb) is the most common intraocular primary malignancy in children. In industrialised countries, the cure rate is about 95%. We present the results of a prospective study on the management of Rb in the paediatric oncology unit of Gabriel Touré Teaching Hospital and African Institute of Tropical Ophthalmology, from November 1, 2011 to December 31, 2015. Procedure The aims of this prospective study were to evaluate the treatment of localised Rb, ocular prosthesis after enucleation, conservative management for bilateral Rb as well as survival rates in all patients. Patients with early stage Rb at diagnosis were included. The treatment was performed according to the retinoblastoma treatment guidelines of the French‐African Paediatric Oncology Group. Results Eighty‐eight patients were included in the study. Sex ratio was 1:1 (M = 44, F = 44). Median age at diagnosis was 3 years (range: 2 months–5 years). Unilateral intraocular Rb was predominant (n = 50; 56.8%). Conservative treatments were performed on nine eyes in nine patients. Overall survival and event‐free survival of the entire cohort at the end of 4 years were 73% (95% CI 60.8–81.2%) and 59% (95% CI 47.9–69.5%), respectively, with a median follow‐up of 3.7 years (0.1–5.6 years). In conclusion, early enucleation in early stage of Rb can improve outcomes in resource‐limited countries. Delayed enucleation and refusal of adherence to treatment are still major concerns and remain a barrier to improving overall patient survival.

Prise en charge des mélanomes oculaires, le minimum pour les oncologues
Uveal melanomas are the most frequent primary malignant eye tumor. Enucleation was historically the gold standard. Since then, several studies showed that conservative treatments did not increase the risk of metastasis or survival. Choroidal melanomas are both radioresistant and located close to visual structures (the optic nerve and macula) of the eye, which may be preserved in some settings without compromising tumor control, as this is the first priority. Different types of radiation therapy may be used for such tumors: brachytherapy and charged particles, including proton beam therapy. If visual prognosis is dependent to the local treatment, the vital prognosis is dependent on the metastatic risk, with a risk of liver involvement in 20 to 50% of patients, depending on tumor size and genomics. Median survival after the discovery of liver metastases is about 15 months. The management of these patients is often complex. Systemic therapies (chemotherapy, targeted therapies, immunotherapy, etc.) yield limited response rates and although local treatments of liver metastases are promising, they are only feasible in selected patients. The mission of the MELACHONAT national network is to improve the management of patients regardless of the stage of the disease. The patient association ANPACO is dedicated to help uveal melanoma patients in their health care path and to promote knowledge dissemination within the patient community. The aim of this review is to focus on the local treatments of uveal melanomas as well as the management of their metastatic evolution.

Travel burden and clinical presentation of retinoblastoma: analysis of 1024 patients from 43 African countries and 518 patients from 40 European countries
The travel distance from home to a treatment centre, which may impact the stage at diagnosis, has not been investigated for retinoblastoma, the most common childhood eye cancer. We aimed to investigate the travel burden and its impact on clinical presentation in a large sample of patients with retinoblastoma from Africa and Europe.A cross-sectional analysis including 518 treatment-naïve patients with retinoblastoma residing in 40 European countries and 1024 treatment-naïve patients with retinoblastoma residing in 43 African countries.Capture rate was 42.2% of expected patients from Africa and 108.8% from Europe. African patients were older (95% CI -12.4 to -5.4, p<0.001), had fewer cases of familial retinoblastoma (95% CI 2.0 to 5.3, p<0.001) and presented with more advanced disease (95% CI 6.0 to 9.8, p<0.001); 43.4% and 15.4% of Africans had extraocular retinoblastoma and distant metastasis at the time of diagnosis, respectively, compared to 2.9% and 1.0% of the Europeans. To reach a retinoblastoma centre, European patients travelled 421.8 km compared to Africans who travelled 185.7 km (p<0.001). On regression analysis, lower-national income level, African residence and older age (p<0.001), but not travel distance (p=0.19), were risk factors for advanced disease.Fewer than half the expected number of patients with retinoblastoma presented to African referral centres in 2017, suggesting poor awareness or other barriers to access. Despite the relatively shorter distance travelled by African patients, they presented with later-stage disease. Health education about retinoblastoma is needed for carers and health workers in Africa in order to increase capture rate and promote early referral.

Functional results after treatment of retinoblastoma
Purpose: Because of the long-term complications associated with external beam radiation in retinoblastoma, alternative treatment methods have been investigated. We conducted a retrospective study to evaluate the functional results of new treatment modalities. Methods: Thirty-seven eyes were treated without external beam irradiation in 31 patients. The median diameter of the largest tumor in each eye was 6 mm. Primary chemotherapy was used in 25 cases, chemothermotherapy was used in 32 cases, cryotherapy was used in 28 cases, iodine 125plaques were used in 15 cases, diode laser thermotherapy was used alone in 11 cases, and photocoagulation was performed in 5 cases. The median follow-up after diagnosis of retinoblastoma was 41 months. The visual results were evaluated at a median age of 54 months. Results: The median visual acuity of the treated eyes was 20/33. Twenty-four eyes presented a visual acuity better than 20/40, 4 eyes had a visual acuity between 20/200 and 20/40, and 9 eyes had a visual acuity less than 20/200. Maculopathy was observed in 16 cases, associated with papillopathy in 1 case. A cataract was observed in 1 case and a vitreous hemorrhage was observed in another case. Twenty-one eyes did not develop any complications. No corneal dryness and very few lens changes were observed. Conclusion: The functional results after local treatments for retinoblastoma are very good. The most frequent complication is maculopathy, particularly when the tumor involves or is situated close to the macula. (J AAPOS 2002;6:108-11)

Combined Proton Beam Radiotherapy and Transpupillary Thermotherapy for Large Uveal Melanomas: A Randomized Study of 151 Patients
&lt;i&gt;Introduction:&lt;/i&gt; Exudation from the tumour scar and glaucoma can be major problems after proton beam irradiation of uveal melanoma and can sometimes lead to secondary enucleation. We conducted a randomized study to determine whether systematic transpupillary thermotherapy (TTT) after proton beam radiotherapy could have a beneficial effect. &lt;i&gt;Patients and Method:&lt;/i&gt;Between February 1999 and April 2003, all the patients treated by proton beam radiotherapy for uveal melanomas ≧7 mm thick or ≧15 mm in diameter were included in this study after giving their informed consent. One half of the patients received proton beam radiotherapy alone (60 Gy in 4 fractions) and the other half received the same dose of proton beam radiotherapy followed by TTT at 1, 6 and 12 months. All the information concerning the initial tumour parameters, treatments and follow-up was recorded and a statistical analysis was performed. &lt;i&gt;Results:&lt;/i&gt; We randomized 151 patients. The median follow-up was 38 months. The 2 groups of patients were similar in terms of age, gender and tumour characteristics. The patients treated with TTT showed a greater reduction of tumour thickness (p = 0.06), less retinal detachment at the latest follow-up (p = 0.14) and a lower secondary enucleation rate (p = 0.02). &lt;i&gt;Discussion:&lt;/i&gt; The present study is the first randomized analysis to demonstrate a significant decrease in the secondary enucleation rate in patients treated with TTT after proton beam radiotherapy. Further studies should be performed to determine whether TTT could be beneficial to smaller tumours and to define its optimal dose.

Familial retinoblastoma: fundus screening schedule impact and guideline proposal. A retrospective study
To assess if systematic fundus screening according to an 'intensive' schedule alters ocular outcome and to propose fundus screening schedule guidelines for children related to a retinoblastoma patient.For children with a positive family history of retinoblastoma, we perform fundus exams shortly after birth under general anaesthesia and then at regular intervals according to schedules based on the risk. Familial retinoblastoma cases seen at our institution from January 1995 to December 2004 were retrospectively classified as 'screened' or 'non-screened' (NS) and, among the 'screened' patients, as 'intensively screened' (IS) if screening matched our recommendations or 'non-intensively screened' (S). Groups were compared by Fisher exact test for categorical variables and Kruskal-Wallis test for continuous variables.Among the 547 retinoblastoma patients managed at our institution during this period, 59 were familial cases. In all, 20 were in the NS group, 23 in the S group, and 16 in the IS group. The number of children enucleated was, respectively, 13, 2, and 0 (P<10(-4)); external beam radiation (EBRT) was required for, respectively, 6, 0, and 2 children (P<0.009). Chemotherapy burden and visual acuity were not significantly different between groups.An 'intensive' fundus screening schedule decreased the need for enucleation and EBRT. Therefore, despite the heavy burden of the screening schedule, we recommend physicians and health-care professionals to better inform and refer children with a family history of retinoblastoma for genetic counselling and proper fundus screening in specialized centres.

Le rétinoblastome : état des lieux au Mali et programme d’aide au diagnostic précoce, aux traitements et à la réhabilitation
Le rétinoblastome (RB) est une tumeur maligne embryonnaire rare et représente 1/16 000 naissances en France. Au Mali, une étude hospitalière a permis de caractériser les cas vus à Bamako dans l’unité d’oncologie pédiatrique de l’hôpital universitaire Gabriel Touré et dans l’Institut d’ophtalmologie tropicale de l’Afrique (IOTA), entre janvier 2005 et juin 2007. L’âge médian au diagnostic était de quatre ans contre deux ans en France pour les formes unilatérales. Près de deux tiers des enfants atteints de RB arrivaient au diagnostic au stade extra-oculaire, ce qui est devenu exceptionnel en France. Il y avait 11 % de formes bilatérales contre 35 % en France. Le taux de guérison était estimé à environ 50 %, mais cela ne concerne que les enfants accueillis à Bamako avec 20 % de perdus de vue, alors qu’il est de plus de 95 % en France où l’enregistrement des cas est exhaustif. Le RB apparaît comme une tumeur exemplaire pour laquelle une amélioration rapide doit pouvoir être apportée dans les pays à bas revenu avec des moyens relativement limités. Cela a incité l’Alliance mondiale contre le cancer (AMCC), l’Institut Curie de Paris, centre de référence en France pour le RB, et les équipes de Bamako de l’hôpital Gabriel Touré et de l’IOTA à proposer un programme d’aide au diagnostic précoce, aux traitements, y compris conservateurs, et à la réhabilitation des enfants atteints de RB en Afrique subsaharienne, en partenariat avec le Groupe franco-africain d’oncologie pédiatrique (GFAOP). Le lancement officiel de la campagne d’information a eu lieu le 4 novembre 2011 à Bamako pour le Mali et les régions avoisinantes. Le programme est en cours d’extension à d’autres pays. Retinoblastoma (RB) is a rare embryonic tumour that represents 1/16,000 births in France. In Mali, a study showed the characteristics of a hospital series of cases seen in Bamako in the Pediatric Oncology Unit of Gabriel Touré Teaching Hospital and in the Tropical Ophthalmology Institute of Africa (IOTA) between January 2005 and June 2007. Median age was 4 years versus 2 years in France for unilateral disease. Near two third of children with RB had extra-ocular extension at diagnosis, which is now exceptional in France. Only 11% were bilateral versus 35% in France. Cure rate was around 50%, but it is estimated only on the cases arriving in Bamako and with at least 20% lost of follow-up. Cure rate is over 95% in France within an exhaustive register. RB appears as an exemplary tumor and rapid improvements could be obtained in low-income countries with relatively limited means. This is why, the Alliance mondiale contre le cancer (AMCC), the Institut Curie in Paris, which is the reference center in France for RB, and teams in Bamako were proposing a program to help the development of early diagnosis, treatments, including eye preservation, and rehabilitation of children with RB in sub-Saharan Africa in collaboration with the Groupe franco-africain d’oncologie pédiatrique (GFAOP). The official launching of this program was held in Bamako November 4th, 2011 for Mali and the surrounding regions. After this first experience, this program is now implemented in other countries.

Conservative treatment of retinoblastoma: a prospective phase II randomized trial of neoadjuvant chemotherapy followed by local treatments and chemothermotherapy
PurposeIntraocular retinoblastoma treatments often combine chemotherapy and focal treatments. A first prospective protocol of conservative treatments in our institution showed the efficacy of the use of two courses of chemoreduction with etoposide and carboplatin, followed by chemothermotherapy using carboplatin as a single agent and diode laser. In order to decrease the possible long-term toxicity of chemotherapy due to etoposide, a randomized neoadjuvant phase II protocol was conducted using vincristine-carboplatin vs etoposide-carboplatin.Patients and methodsThe study was proposed when initial tumor characteristics did not allow front-line local treatments. Patients included in this phase II noncomparative randomized study of neoadjuvant chemotherapy received vincristin-carboplatin (new arm) vs etoposide-carboplatin (our reference arm). They were subsequently treated by local treatments and chemothermotherapy. Primary end point was the need for secondary enucleation or external beam radiotherapy (EBRT) not exceeding 40% at 2 years.ResultsA total of 65 eyes in 55 children were included in the study (May 2004 to August 2009). Of these, 32 eyes (27 children) were treated in the arm etoposide-carboplatin and 33 eyes (28 children) in the arm vincristin-carboplatin. At 2 years after treatment, 23/33 (69.7%) eyes were treated and salvaged without EBRT or enucleation in the arm vincristin-carboplatin and 26/32 (81.2%) in the arm etoposide-carboplatin.ConclusionEven if the two treatment arms could be considered as sufficiently active according to the study decision rules, neoadjuvant chemotherapy by two cycles of vincristine-carboplatin followed by chemothermotherapy appear to offer less optimal local control than the etoposide-carboplatin combination.

The biological and prognostic significance of angiotropism in uveal melanoma
<h2>Abstract</h2> Angiotropism is a marker of extravascular migration of melanoma cells along vascular and other structures and a prognostic factor in cutaneous melanoma. Because of this biological and prognostic importance in cutaneous melanoma, angiotropism was studied in uveal melanoma (UM). This retrospective study performed at a single ocular oncology referral center included 89 patients from the study period 2006–2008. All patients were diagnosed with UM from the choroid and/or ciliary body. All patients underwent enucleation for prognostic purposes and definitive therapy. Clinical, histopathological, and molecular variables included patient age, gender, extraocular extension, tumor location (ciliary body or not), optic nerve invasion, angiotropism, neurotropism, melanoma cell type, BAP1 mutation, and monosomy 3. Angiotropism was defined as melanoma cells arrayed along the abluminal vascular surfaces without intravasation in the sclera and/or episcleral tissue. The study included 51 women (57.3%) and 38 men with mean and median age: 63 years (range: 25–92). Mean follow-up was 4.4 years (range: 0.2 to 11). Fifty-three (59.6%) patients developed metastases and 48 (53.9%) were dead from metastases at last follow-up. Other principal variables recorded were angiotropism in 43.8%, extraocular extension in 7.9%, epithelioid/mixed cell type in 73.1%, BAP1 mutation in 41.3%, and monosomy 3 in 53.6% of cases. On multivariate analysis, extraocular extension, angiotropism, and monosomy 3 were predictive of metastasis, whereas tumor diameter, epithelioid cell type, angiotropism, and monosomy 3 were predictive of death. Chi-square test confirmed an association between angiotropism and metastasis and death but none with BAP1 mutation and monosomy 3. In conclusion, angiotropism and monosomy 3 were independent prognostic factors for both metastases and death in UM. However, irrespective of any prognostic value, the true importance of angiotropism is its biological significance as a marker of an alternative metastatic pathway.

Prospective study of surveillance testing for metastasis in 100 high-risk uveal melanoma patients
Despite advances in the local treatment of UM, half of patients develop metastases typically to the liver with poor survival. Microscopic complete surgical resection (R0) of liver metastases improves survival in high selected patients. Early identification of high-risk patients might allow detection of asymptomatic metastases, and increase R0 liver surgery rate. From October 2006 to December 2009, we conducted a prospective study to detect early minimal lesions with 6-monthly liver function tests (LFTs) and liver MRI in 100 high-risk patients. High risk was defined by primary tumor clinical or genomic criteria: thickness > 8 mm or diameter > 15 mm, or extra-scleral extension, or monosomy 3 by FISH or aCGH. With a median follow-up of 49 months, the 5-year metastasis-free survival and overall survival were 47 and 33%, respectively. Of the 60 patients who became metastatic, 50 (83%) had exclusive liver metastasis. LFTs screening had no sufficient accurary, but biannual MRI showed high predictive value to detect metastasis and select patients eligible for curative surgery: 25/50 underwent laparotomy and among them, 8/25 (32%) had a R0 surgery. Median survival after metastasis was 14 months, mean survival reached 40 months in the R0 resected population. Six-monthly liver MRI screening is recommended in patients with large tumors or genomic high risk in order to detect early patient candidates to complete resection of liver metastases. Malgré un traitement local optimal du mélanome uvéal, la moitié des patients vont développer des métastases le plus souvent hépatiques, de très mauvais pronostic. Seuls les patients bénéficiant d’une chirurgie microscopiquement complète d’une atteinte métastatique hépatique limitée ont une survie prolongée. La détection précoce de telles métastases chez les patients à haut risque de rechute et asymptomatiques permet d’espérer un meilleur taux de chirurgies complètes. D’octobre 2006 à décembre 2009, nous avons mené une étude prospective testant le bilan sanguin de la fonction hépatique et l’imagerie par IRM tous les 6 mois chez 100 patients à haut risque, défini sur des critères cliniques ou génomiques de la tumeur primitive : épaisseur > 8 mm ou diamètre > 15 mm, ou extension extrasclérale, ou monosomie par FISH ou CGH. Avec un suivi médian de 49 mois, la survie sans métastase et la survie globale à 5 ans sont de 47 et 33 %, respectivement. Parmi les 60 patients qui ont développé des métastases, 50 (83 %) avaient une atteinte hépatique exclusive. Les tests sanguins de la fonction hépatique n’ont pas permis la détection des métastases au stade infraclinique ; en revanche l’IRM hépatique, avec une sensibilité et une valeur prédictive négative de 100 %, a permis de sélectionner les patients éligibles à une chirurgie curative : 25/50 ont bénéficié d’une laparotomie et parmi eux, 8/25 (32 %) d’une chirurgie R0. La survie médiane après diagnostic des métastases est de 14 mois pour l’ensemble des patients, la survie moyenne des 8 patients opérés R0 atteint 40 mois dans cette étude. Un suivi semestriel par IRM hépatique est donc recommandé chez les patients atteints de mélanome uvéal à haut risque clinique ou génomique dans le but de détecter précocement les patients candidats à une chirurgie complète des métastases hépatiques.

Results of external beam radiotherapy for diffuse choroidal hemangiomas in Sturge–Weber syndrome
The Sturge-Weber Syndrome (SWS) is a phacomatosis which include facial nevus flammeus, glaucoma, diffuse choroidal hemangioma, and leptomeningeal hemangiomatosis. External beam radiotherapy (EBRT) using photons was used to treat retinal detachment. We investigate the anatomical and functional results in a long-term basis.Retrospective review of SWS patients treated by EBRT (20 Gy in 10 fractions) for an exudative diffuse choroidal hemangioma. Visual acuity, B-scan tumor thickness, size of retinal detachment, intra-ocular pressure, and hypotonic treatment were collected before EBRT, 1 year after, and at the latest news.Twenty-five patients (26 eyes) were treated between 2001 and 2014. Retinal detachment including the macula was found among twenty-six eyes before treatment. The average follow-up time was 47 months. The mean tumor thickness was initially 4.5 mm, 2.8 mm at first year, and 2.7 mm at the last visit. The retina was reattached at the last visit for all eyes except two. The visual acuity was stable or better for 20 eyes (p = 0.02). Four patients developed mild cataract during the follow-up.EBRT using 20 Gy in 10 fractions is efficient, decreases tumor thickness, reattaches the retina, and stabilizes visual acuity. In the long term, retinal reattachment allows ocular conservation by preventing phthisis bulbi.

Development of a Prognostic Nomogram for Liver Metastasis of Uveal Melanoma Patients Selected by Liver MRI
Patients with liver metastases of uveal melanoma (LMUM) die from their metastatic evolution within 2 years. We established a nomogram to choose a treatment adapted to life expectancy. From 2002 to 2013, we reviewed 224 patients with LMUM selected by liver MRI. A nomogram was developed based on a Cox model. The predictive performance of the model was assessed according to the C-statistic, Kaplan-Meier curve, and calibration plots. The median follow-up was 49.2 months (range, 0.6-70.9). The survival rates at 6, 12, and 24 months were 0.88 (0.95 CI [0.84-0.93]), 0.68 (0.95 CI [0.62-0.75]), and 0.26 (0.95 CI [0.21-0.33]), respectively. The four factors selected for the nomogram with a worse prognosis were: A disease-free interval between the UM and LMUM groups of less than 6 months (HR = 3.39; 0.95 CI [1.90-6.05]), more than 10 LMUM (HR = 3.95; 0.95 CI [1.97-4.43]), a maximum LMUM of more than 1200 mm2 (HR = 2.47; 0.95 CI [1.53-3.98]), and a lactate dehydrogenase (LDH) value greater than 1.5 (HR = 3.72; 0.95 CI [2.30-6.00]). The model achieved relatively good discrimination and calibration (C-statistic 0.71). This nomogram could be useful for decision-making and risk stratification for therapeutic options.

External radiotherapy for carcinoma of the eyelid: Report of 850 cases treated
We report a retrospective series of 850 patients treated by external irradiation for carcinoma of the eyelid at Institut Curie and we compare our results with other techniques: brachytherapy and surgery.Eight hundred fifty patients were treated by external radiotherapy for carcinoma of the eyelid. None of these patients have been previously treated. All the patients were classified according to the TNM classification of (UICC). We distinguished five histological types and five clinical groups according to the site of the skin tumor. Three modalities of external radiotherapy were used: contact therapy, conventional radiotherapy, and electrontherapy. We reviewed the clinical files of the 850 patients who went regularly at follow-up visits.We report the 5-year survival results--alive with no evidence of disease: 72%; alive with progression: 2%; died from tumor progression: 0.5%; died from intercurrent disease: 19.5%; and lost to follow-up: 5%. The 5-year local control rate was 97.5%. We observed 45 failures--lymph node, metastatic, and local--and emphasize this last group by presenting the results of treatment of these local failures. We studied the complications of treatment: 2.3% of corneal complications, 2% of cataracts, and 1.4% of serious ocular complications.Our results concerning local failures and loss of the eye are comparable to those reported for other techniques involving brachytherapy or surgery. Overall, external radiotherapy is a safe and effective treatment, as it ensures a high local control rate and provides perfectly satisfactory functional and esthetic results. It seemed particularly useful to report this series in that few publications are available on this subject that, nevertheless, constitutes a topical issue.

BRAF as a melanoma susceptibility candidate gene?
A high frequency of activating BRAF somatic mutations have been identified recently in malignant melanoma and nevi indicating that BRAF activation could be an early and critical step in the initiation of melanocytic neoplasia. To determine whether BRAF mutations could be an earlier event occurring at the germline level, we screened the entire BRAF coding region for germline mutations in 80 independent melanoma-prone families or patients with multiple primary melanoma without a familial history. We identified 13 BRAF variants, 4 of which were silent mutations in coding regions and 9 nucleotide substitutions in introns. None of these BRAF variants segregated with melanoma in the 11 melanoma families studied. Moreover, there was no significant difference in the frequency of heterozygotes for BRAF variants between melanoma cases and controls when they were compared. Our data suggest that BRAF is unlikely to be a melanoma susceptibility gene.

Proton beam therapy for iris melanomas
To describe the results in terms of local control, eye preservation and systemic evolution of iris melanomas treated by proton beam irradiation.Retrospective review of the charts of patients with iris melanoma treated by proton beam therapy between April 1998 and September 2002. Ciliary body melanomas with iris involvement or tumours with extrascleral invasion were excluded. Treatment consisted of 60 Gy of proton beam irradiation delivered in four fractions to the tumour volume.A total of 21 patients were treated, median follow-up of 33 months (8-72 months). 15 patients presented a lesion with documented growth. The median clinical diameter was 5 mm (2-8 mm), the median ultrasound diameter 4.8 mm (2-7.7 mm) The patients were 6% T1, 57.1% T2, and 14.3% T3 all N0M0. The iridocorneal angle was invaded by the tumour in 71.4% of patients. At the end of follow-up, all patients were alive with no proven metastatic disease except one patient with suspicious liver lesions. None of the patients showed tumour progression or ocular relapse. The tumour response at 2 years was a flat lesion for 6.3% of cases, partial regression in 75% and stable in 18.8%. None of the patients required secondary enucleation. The main complication was cataract (45% within 24 months of treatment). Raised intraocular pressure was observed in 15% of patients but no neovascular glaucoma.Proton beam therapy shows potential utility for selected cases of localised iris melanomas allowing excellent local tumour control and eye preservation. Further follow-up on larger series is needed to confirm these results.

Facteurs pronostiques du mélanome malin de l’uvée
We conducted a retrospective study on the clinical factors influencing the local and general prognosis of patients treated for uveal melanoma with a preliminary analysis of the prognostic value of monosomy 3.and method: The patients sent to Curie Institute for uveal melanoma have a complete initial clinical evaluation, conservative management by radiotherapy or enucleation, and local and general long-term follow-up. Over the last 5 years, the status of chromosome 3 has been assessed by FISH in the tumors of enucleated patients. Findings concerning the initial workup, treatment, and follow-up are recorded prospectively. We conducted a retrospective study with multivariate analysis of the clinical factors influencing local recurrence, ocular conservation metastasis, and survival and studied the effect of monosomy 3.A total of 2241 patients were registered with a median follow-up of 72 months. Of these patients, 92.8% had conservative management with iodine 125 brachytherapy or proton beam therapy and 7.2% of the patients had enucleation (n=160). Tumors from 120 patients were studied for the status of chromosome 3 by FISH. The overall survival rate was 76.3% and the metastatic rate was 19.5%. The clinical factors influencing survival were the size and location of the tumor, age of the patient, gender, and initial treatment. The factors influencing the metastatic risk were the same plus retinal detachment and local recurrence. Monosomy 3 was a significant risk factor for metastatic disease.This study found the usual risk factors with the difference that location on the equator seems to be of worse prognosis than ciliary body involvement for survival and metastasis. In addition, the initial retinal detachment appears to be a risk factor for local recurrence and metastasis. At present, the evaluation of chromosome 3 is available for enucleated tumors but it could probably be done on needle biopsy performed during conservative management as well.This study confirms previous results on the prognostic factors of uveal melanoma and on the value of monosomy 3. The increasingly precise identification of a group of high-risk patients should allow us to propose adjuvant therapy and to adapt follow-up.

Uveal melanoma: management and outcome of patients with extraocular spread
BACKGROUND Extraocular spread is thought to be a negative prognostic factor on the survival in patients with uveal melanoma. Enucleation was the standard treatment in these patients. Today, depending on the size of the tumour and the type of extraocular extension, eye-preserving irradiation treatments, such as proton beams or radioactive plaques, may be employed. METHODS 2256 patients were treated between 2000 and 2007 at the Institut Curie, Paris, France for a uveal melanoma. 67 patients (3.0%) presented an extraocular extension. A retrospective study was performed to evaluate the patients' outcomes with regard to tumour recurrence and survival. RESULTS Eye-conserving treatment was employed in 38 (52.8%) patients. Enucleation was performed in 29 (47.2%) patients. The median follow-up was 38 (range 7 to 79) months with an overall survival rate at 5 years of 40.4% in enucleated patients and 79.3% in the eye-conserving treatment group (protons n=19, iodine-125 plaque n=19) (p=0.01; Kaplan-Meier analysis). No tumour recurrence was observed in any group. The degree of extraocular spread as well as the clinical characteristics tumour location, retinal detachment, ciliary body involvement (p<0.01; chi(2) test) and tumour thickness (p=0.04; chi(2) test) influenced the choice of treatment. Age, tumour diameter, involvement of optic nerve, vitreous haemorrhage and the amount of pigment did not have any influence. CONCLUSIONS Tumour recurrence rates and survival rates were not adversely affected in patients receiving conservative eye treatment. This may thus represent a therapeutic option in certain patients with extraocular spread.

Upcoming translational challenges for uveal melanoma
The past few years have witnessed major advances in the understanding of the molecular landscape of uveal melanoma (UM). The discovery of a mutational background that is completely different from the one of skin melanoma has granted to UM a stand-alone status. The absence of effective therapy for metastatic disease offers now a chessboard for targeted therapy but at the same time urges preclinical science to develop accordingly, to guide the use of economical resources to the best profit of patients. This review describes the current knowledge on the biology of this disease and discusses the challenges that must be undertaken to translate this knowledge into real benefit for patients.

Recommandations pour le diagnostic de prédisposition génétique au mélanome cutané et pour la prise en charge des personnes à risque
Cutaneous melanoma is a multifactorial disease resulting from both environmental and genetic factors. Five susceptibility genes have been identified over the past years, comprising high-risk susceptibility genes (CDKN2A, CDK4, and BAP1 genes) and intermediate-risk susceptibility genes (MITF, and MC1R genes). The aim of this expert consensus was to define clinical contexts justifying genetic analyses, to describe the conduct of these analyses, and to propose surveillance recommendations. Given the regulatory constraints, it is recommended that dermatologists work in tandem with a geneticist. Genetic analysis may be prescribed when at least two episodes of histologically proven invasive cutaneous melanoma have been diagnosed before the age of 75 years in two 1st or 2nd degree relatives or in the same individual. The occurrence in the same individual or in a relative of invasive cutaneous melanoma with ocular melanoma, pancreatic cancer, renal cancer, mesothelioma or a central nervous system tumour are also indications for genetic testing. Management is based upon properly managed photoprotection and dermatological monitoring according to genetic status. Finally, depending on the mutated gene and the familial history, associated tumour risks require specific management (e.g. ocular melanoma, pancreatic cancer). Due to the rapid progress in genetics, these recommendations will need to be updated regularly.

Treatment of retinoblastoma: The Institut Curie experience on a series of 730 patients (1995 to 2009)
To describe the results of retinoblastoma treatment from 1995-2009 in a single institution.Retrospective review of the charts of patients treated for retinoblastoma. Clinical characteristics at diagnosis, treatments and outcomes in terms of survival and ocular preservation are described.During the study period 826 children were referred for retinoblastoma and 730 were managed in our institution. Four hundred and eleven children presented with unilateral retinoblastoma and 319 with bilateral retinoblastoma. Median follow-up is of 93 months. Global survival is 98.5% of children, 10 children presented with second tumors, 11 children died (6 of tumor-related causes). Of the 411 children with unilateral retinoblastoma enucleation was needed at diagnosis for 324 (78.8%). Conservative treatments were attempted for 87 patients (21.2%) and ocular preservation obtained for 65 patients (74% of eyes). Three hundred and nineteen patients presented with bilateral retinoblastoma. Three hundred and ten could be treated conservatively for at least one eye. Initial intravenous chemotherapy was necessary for 75% of them. Ocular preservation without external beam radiation was possible for 221 patients (70%). The use of EBR decreased significantly after 2004 (9.1% of eyes vs 25.1%: P<0.001).Management and treatment of retinoblastoma are complex, adapted to the extent of the disease. Survival is good. Enucleation is still required for extensive ocular disease, especially for unilateral patients. Intravenous chemotherapy allows good tumor control and eye preservation and decrease the need of EBR.Retinoblastoma treatment with intravenous chemotherapy and ocular adjuvant therapies is very effective on the local tumor control and eye preservation.

Résultats préliminaires de la protonthérapie du mélanome de la choroïde au centre de protonthérapie d'Orsay (CPO): Les 464 premiers cas
Retrospective analysis of the treatment of choroidal melanoma with protontherapy at the Centre de protonthérapie d'Orsay, France.Between September 1991 and September 1995, 612 patients presenting with choroidal melanoma were treated by protontherapy in Orsay. Following initial management of the first 464 patients, results were analyzed, as were results after a 1-year follow-up for 305 patients, a 2-year follow-up for 169 patients, and a 3-year follow-up for 59 patients.Univariate analysis showed that the actuarial local recurrence rate was 5%, the 3-year survival rate 88%, and the overall metastasic rate 5%. The initial tumor volume was the most significant predictive factor for visual results and metastases. Multivariate analysis revealed that visual results were significantly related to the initial tumor volume, initial retinal detachment, and total dose delivered to the optic nerve and macula.Protontherapy of choroidal melanoma allows in most cases conservation of the eye without modification of survival. Visual results mainly depend on the site and size of the tumor.

Episodic Src activation in uveal melanoma revealed by kinase activity profiling
The RAS/RAF/MEK/ERK pathway is involved in the balance between melanocyte proliferation and differentiation. The same pathway is constitutively activated in cutaneous and uveal melanoma (UM) and related to tumour growth and survival. Whereas mutant BRAF and NRAS are responsible for the activation of the RAS/RAF/MEK/ERK pathway in most cutaneous melanoma, mutations in these genes are usually absent in UM.We set out to explore the RAS/RAF/MEK/ERK pathway and used mitogen-activated protein kinase profiling and tyrosine kinase arrays.We identified Src as a kinase that is associated with ERK1/2 activation in UM. However, low Src levels and reduced ERK1/2 activation in metastatic cell lines suggest that proliferation in metastases can become independent of Src and RAS/RAF/MEK/ERK signalling. Inhibition of Src led to the growth reduction of primary UM cultures and cell lines, whereas metastatic cell line growth was only slightly reduced.We identified Src as an important kinase and a potential target for treatment in primary UM. Metastasis cell lines seemed largely resistant to Src inhibition and indicate that in metastases treatment, a different approach may be required.

Long‐term evaluation of orbital rhabdomyosarcoma in children
Abstract Background Orbital rhabdomyosarcoma ( ORMS ) is associated with an excellent survival rate greater than 85%, and is considered to be a favourable site for this tumour. Treatment is based on combination chemotherapy together with best local therapy, sometimes surgery but more often radiation therapy. Local therapy is associated with frequent and potentially severe late sequelae. Design Retrospective hospital single‐centre analysis. Participants Eighty‐two patients treated in I nstitut C urie, P aris. Methods To define long‐term status of survivors after localized ORMS , patients treated between 1975 and 2010 were analysed. Main Outcome Measures Clinical structural and functional orbital, and general sequelae. Results Median age at diagnosis was 6 years (range: 8 months–19 years), and median follow up was 8.5 years (range: 7 months–24 years). The 5‐year globe conservation rate was 90.4%. Ophthalmic dysfunction was present in 79% of patients. Impaired visual acuity ( VA ), was present in 62% of patients; 38% of them had severe visual disability with VA &lt; 6/60. Late effects on orbitofacial structure were present in 39.8% of patients. Ocular or palpebral sequelae were present in 79% of survivors, mainly cataract (42%), ocular surface lesions such as keratoconjunctivitis (40%) and eyelid abnormalities (29%). General late effects were rare. Conclusions These data suggest that ocular and orbital late effects are frequent after treatment of ORMS , indicating the need for systematic long‐term ophthalmologic follow up of these patients. Radiation therapy is an important part of the total burden of therapy.

Satellite in transit metastases in rapidly fatal conjunctival melanoma: implications for angiotropism and extravascular migratory metastasis (description of a murine model for conjunctival melanoma)
Little information is currently available concerning loco-regional metastases such as satellite and in transit metastases and their natural history in conjunctival melanoma as compared to cutaneous melanoma. Angiotropism, a marker of extravascular migration of melanoma cells along vascular channels, often appears responsible for microscopic satellite, satellite and in transit metastases development in cutaneous melanoma. In addition, diffuse tissue microscopic satellites are correlated with widespread melanoma dissemination and death. Herein we report rapid conjunctival melanoma progression and a fatal outcome in four of five patients following recurrence as satellite in transit metastases. Five patients aged 31, 60, 63, 56, and 67 years developed primary conjunctival melanoma, histologically characterised by tumour thicknesses of 4, 4, 1.1, 3, and 2 mm. Two or more conjunctival melanomas manifested ulceration, significant mitotic rates, necrosis, angiotropism, and intralesional transformation. The conjunctival melanoma recurred in a matter of months as one or more discrete satellite in transit lesions in the vicinity of the primary melanoma. Histological examination revealed well-defined micronodules containing atypical melanocytes in the subepithelial connective tissue stroma. All lesions were extravascular and most appeared angiotropic. Four of five patients subsequently developed parotid or other loco-regional nodal disease and rapidly ensuing widespread metastases and death. The time course from diagnosis to the demise of the patients averaged about 13 (range 7-20) months. Our findings suggest that satellite in transit metastases constitute an important new risk marker for possible rapid metastatic disease progression and death in patients with conjunctival melanoma. This finding appears to take on even greater significance if such lesions develop rapidly, i.e., in a matter of weeks or months following diagnosis of primary conjunctival melanoma, and if the primary melanoma manifests additional high-risk features. Additional studies are underway in order to further elucidate the mechanism of these metastases.

Nonocular Second Primary Tumors After Retinoblastoma
The objective of this study was to assess the role of various clinical and treatment factors involved in the long-term incidence of nonocular second primary tumors following retinoblastoma. The study was based on 111 patients treated between 1963 and 1977 according to the same radiotherapy protocol (electron beam radiotherapy) alone or in combination with triethylene melamine (TEM). Various statistical methods were used to obtain the actuarial survival curve, the cumulative incidence of second primary tumors, and comparisons of patient groups and subgroups. The 5-, 10-, 20-, and 30-year survival rates were 75%, 70%, 63%, and 55% with a follow-up of 23 to 35 years. The study reports the various parameters concerning 111 children and 17 second primary tumors: sex, age at treatment, histology of the retinoblastoma and second primary tumors, site of second tumors (anatomic and compared with irradiation field), radiation dose, time to onset, and chemotherapy with or without TEM. The results are discussed and compared with the data reported in the literature. Electron beam radiotherapy at a dose of 45 Gy does not eliminate the risk of nonocular second primary tumors. TEM also does not modify survival or the overall incidence of second primary tumors, but significantly increases the risk of second primary tumors outside the irradiation field.

Melanocytomas of the optic disk
To evaluate the various forms of clinical presentation, the potential of growth, the risk of functional loss and the possibility of malignant transformation of optic disk melanocytomas in European patients.Retrospective observational case control study.Evaluation of 37 cases of optic disk melanocytomas identified in the computer files of the ocular oncology unit of Jules Gonin Hospital to determine the clinical presentation of these tumors and the risk of complications.The tumor was asymptomatic in 28 cases. Visual acuity was normal in 26 cases, subnormal in 10 cases, and in one case it was reduced to 0.1. Visual field defects were observed in 19 cases; the size and extent of the tumor and the degree of papilledema appeared to influence the severity of the visual field defect. Tumor growth was demonstrated in 6 of the 9 cases in which follow-up was for at least six years. In two cases there was presumed malignant transformation that was treated by accelerated proton beam radiotherapy.Melanocytomas in white Europeans and those of European derivation are rarely symptomatic, have only a moderate effect on visual function and show a low rate of progression over long observation. The risk of tumor progression, although sometimes occurring as much as several years after the initial diagnosis, justifies a cautious approach with long-term regular surveillance of these patients.

Imagerie des tumeurs du segment antérieur : avantages respectifs de l’échographie (10, 20 et 50 MHz) et de la tomographie en cohérence optique
Detail the role of different imaging techniques for diagnosis of tumors of the iris.Sixty-one tumors of the iris were explored using ultrasound at 10 and 20MHz (Cinescan, BVI Quantel Medical) and 50MHz (UBM, Paradigm) and optical coherence tomography (OCT) (Humphrey Zeiss).Ultrasound should be used at frequencies of 20MHz or greater to precisely characterize, localize and measure a lesion. Ultrasound biomicroscopy (UBM) is inadequate to measure large tumors (extending toward the back of the ciliary body), because of the transducer and the considerably lower image quality caused by the lesion. Ultrasound alone cannot characterize a solid lesion, and moreover cannot differentiate benign and malignant lesions. Clinical notions are also important in diagnosis and patient management. OCT recognizes whether a lesion is liquid or solid in certain cases.With a tumor that seems solid, a 50MHz examination must be done rapidly, and if the entire lesion is difficult to see, a 20MHz ultrasound should be used. With a protruding iris, high-frequency ultrasound and OCT differentiate a cystic lesion from a solid mass, but only BMU provides a precise measurement and regular surveillance capabilities.

Conjunctival low-grade non-Hodgkin's lymphoma: a large single-center study of initial characteristics, natural history and prognostic factors
To define the initial characteristics and prognostic factors of patients with conjunctival low-grade malignant lymphoma, all patients treated for low-grade lymphoma with initial conjunctival involvement were reviewed. Forty-nine cases were selected, including 45 cases with exclusive ophthalmologic conjunctival involvement. Pathologic review showed 55% of mucosa-associated lymphoid tissue type lymphoma, and 23% of lymphoplasmocytic lymphoma. Initial characteristics were median age of 62 years, nodal involvement in 17% of cases, and stage IV in 22% of patients with 10% of bone marrow involvement. With a median follow-up of 75 months, the 5-year disease-free survival (DFS) and overall survival were 65% and 83%, respectively. On multivariate analysis, nodal involvement was the only factor with a pejorative impact on DFS. Our patient cohort represents one of the largest published series defining the characteristics and prognostic factors of primary conjunctival low-grade malignant lymphoma.

Deeper in the human cornea proteome using nanoLC–Orbitrap MS/MS: An improvement for future studies on cornea homeostasis and pathophysiology
The cornea is a transparent, avascular, and highly specialized connective tissue that provides the majority of light refraction in the optical system of the eye. The human cornea is composed of several layers interacting in a complex manner and possessing specific functions, like eye protection and optical clearness. Only few proteomic studies of mammalian cornea have been performed leading to the identification of less than 200 proteins in human corneas. The present study explores the proteome of the intact normal human cornea using a shot-gun nanoLC-MS/MS strategy and an LTQ Orbitrap mass spectrometer. A total of 2070 distinct corneal proteins were identified from five human cornea samples, which represents a 14-fold improvement in the number of proteins identified so far for human cornea. This enlarged dataset of human corneal proteins represents a valuable reference library for further studies on cornea homeostasis and pathophysiology. Network and gene ontology analyses were used to determine biological pathways specific of the human cornea. They allowed the identification of subnetworks of putative importance for corneal diseases, like a redox regulation and oxidative stress network constituted of aldehyde and alcohol dehydrogenases, most of them being described for the first time in human cornea.
