Abstract
Introduction Local recurrence of conjunctival melanoma (CM) is common after excision. Local radiotherapy is an effective adjuvant treatment option, and brachytherapy with ruthenium-106 (106Ru) is one such option. Thus, herein, we aimed to describe our experience with and the clinical results of post-excision adjuvant 106Ru plaque brachytherapy in patients with CM. Methods Nineteen patients (8 men and 11 women) received adjuvant brachytherapy with a 106Ru plaque after tumor excision. The mean adjuvant dose administered was 109 Gy (range, 80-134 Gy), and a depth of only 2.2 mm was targeted because the tumor had been excised. A full ophthalmological examination including visual acuity testing, slit-lamp examination, and indirect ophthalmoscopy was performed before therapy and at every postoperative follow-up. The mean follow-up period was 62 months (range, 2-144 months). Results Three patients developed a recurrence in a nontreated area, at either the conjunctiva bulbi or the conjunctiva tarsi. None of the patients developed a recurrence in the treated area. The local control rate was 84% (16/19). Conclusion 106Ru plaque brachytherapy is an effective adjuvant treatment to minimize the risk of local recurrence after excision of a CM. Patients have to be followed up regularly and carefully for the early detection of recurrence.

American Joint Committee on Cancer (AJCC) tumor staging system predicts the outcome and metastasis pattern in conjunctival melanoma. Ophthalmology 2022; 129:771-780. [PMID: 35245602 DOI: 10.1016/j.ophtha.2022.02.029] [Citation(s) in RCA: 11] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/03/2021] [Revised: 02/21/2022] [Accepted: 02/22/2022] [Indexed: 12/22/2022] Open
Abstract
PURPOSE To assess the predictive value of the tumor staging system in the eighth edition of the American Joint Committee on Cancer Cancer Staging Manual (AJCC 8th-Edition) and histologic features for outcomes and metastasis patterns in conjunctival melanoma (CM). DESIGN Retrospective, single-center cohort study. PARTICIPANTS Eighty-three patients with CM were treated at our center between 2000 and 2021. METHODS We reviewed clinical and histopathological parameters and used Kaplan-Meier survival curves and Cox proportional hazards regression models for risk factor analyses. MAIN OUTCOME MEASURES Time to nodal/distant metastasis, disease-specific survival, metastatic pattern, and metastatic site. RESULTS At presentation, five patients (6%) had cT1 disease, 34 (41%) had cT2 disease, and 44 (53%) had cT3 disease. Four (5%) patients had nodal metastasis (N1), and none had distant metastasis (M1). During follow-up, 12 (14%) developed nodal metastasis, 29 (35%) developed distant metastasis, and 26 (31%) died of disease. Brain, liver and lung were common distant metastasis sites. Higher cT category was associated with increased risks of distant metastasis (p<0.001) and disease-specific death (p=0.002). The separate analysis of primary and recurrent tumors at presentation showed that the patients with cT3 tumors took a much higher risk of distant metastasis than those with cT2 tumors. Greater tumor thickness, ulceration, and the presence of regression were correlated with distant metastasis. Previously unreported mutations were detected in the tumor suppressor genes: FAT4 and SYK. Among the 29 patients who developed distant metastasis, we analyzed two patterns of metastasis: 11 patients (38%) developed nodal metastasis prior to distant metastasis, and 18 patients (62%) developed distant metastasis without previously known nodal metastasis. The patients with cT3 tumors were more likely to follow the latter metastasis pattern (p=0.02). CONCLUSION CM presented with mostly advanced stages and high rates of distant metastasis in the current Chinese cohort. This study confirmed the prognostic value of the tumor staging system in the AJCC 8th-Edition in Chinese patients. Histologic features, such as tumor thickness and ulceration, should be emphasized when assessing prognosis and guiding the treatment of CM.

Abstract
OBJECTIVE This study aims to explore the mechanism of miR-30d-5p in regulating the development of lung squamous cell carcinoma (LUSC) via targeting DBF4. METHODS Bioinformatics methods were employed to analyze the differentially expressed genes in LUSC tissue microarray. qRT-PCR was employed to detect the expression of miR-30d-5p and DBF4 mRNA in normal human bronchial epithelial cells and LUSC cells. CCK-8 was used to detect LUSC cell activity. Wound healing assay was employed to detect the migratory ability of LUSC cells. Transwell was employed to detect invasive ability. Dual-luciferase reporter assay was used to detect the targeting relationship between miR-30d-5p and DBF4. Western blot was used to detect the protein expression of marker molecules associated with epithelial-mesenchymal transition (EMT). RESULTS In this study, the expression of miR-30d-5p in LUSC cell lines was found to be obviously low compared with that in normal human bronchial epithelial cell line, which was opposite to the expression of DBF4. Dual-luciferase reporter assay verified that miR-30d-5p could target DBF4 and the overexpression of miR-30d-5p downregulated the expression of DBF4. Overexpression of DBF4 promoted the proliferation, migration, invasion, and EMT of LUSC, whereas over-expression of miR-30d-5p could weaken the promotion of DBF4 on cancer cells. CONCLUSION miR-30d-5p downregulates the expression of DBF4 to regulate the development of LUSC.

Abstract
BACKGROUND Growing evidence supports an individualised approach rather than radical surgery for conjunctival melanoma (CM). This study aimed to compare the long-term outcome between individualised and conventional exenteration techniques. METHODS Our study retrospectively recruited advanced CM (clinical T3 stage) patients treated with individualised (13 cases) or conventional (18 cases) exenteration from June 2014 to April 2019. The individualised approach preserved at least three quadrants of the orbit, and the conventional procedures removed at least one third of the orbital tissues. The medical records were collected and analyzed during April 2020, including demographics, tumour characteristics, surgical details, postoperative rehabilitation and tumour-related prognosis. RESULTS The tumour basal diameter was statistically (P = 0.011) larger in the conventional group (23.3 ± 7.6 mm) than in the individualised group (15.4 ± 6.3 mm). More tissues were preserved in the individualised group, resulting in a shorter duration of wound healing (2.1 ± 0.6 vs. 3.6 ± 2.0 weeks, P = 0.018) and less incidence of hollow appearance (15% vs. 72%, P = 0.003) than the conventional group. After follow-up for 39.3 ± 17.3 months, a comparison of survival curves showed no significant differences (P = 0.638) between the two groups. The 1- and 2-year overall survival rates were estimated as 100% and 80.0% in the individualised group, and 93.8% and 72.5% in the conventional group, respectively. Low or mixed pigmentation was identified as the risk factor for tumour-related mortality based on multivariate regression analysis. CONCLUSIONS The individualised approach to exenteration offers improved aesthetic results while still maximises the curable chance for advanced CM.

Abstract
Importance Conjunctival melanoma (CM) is a rare ocular tumor. Estimates of incidence and survival of patients with CM are important to researchers and policy makers. Objective To estimate incidence and survival of patients with CM in Europe. Design, Setting, and Participants This population-based cohort study used data from 41 European cancer registries adhering to the RARECAREnet project. All individuals diagnosed as having malignant CM from January 1995 to December 2007 coded according to the International Classification of Diseases for Oncology, Third Edition codes C69.0 (conjunctiva) and 8720-8780 (melanoma) were included. Analysis began March 2019. Main Outcomes and Measures Trend estimates for incidence and for 5-year relative survival (the ratio of the measured survival of patients to the expected survival in the general population for the same country, age, sex, and calendar year). Crude, age-standardized, and bayesian incidence rates were calculated. Five-year relative survival was calculated by the Ederer II method with the cohort and period approach. Results A total of 724 patients 15 years or older (512 [70.7%] were 55 years or older; 366 [50.6%] were female) were analyzed with an overall crude incidence of CM (per 1 000 000 person/y) of 0.46 (95% CI, 0.42-0.49). Crude incidence was similar in men and women (0.48; 95% CI, 0.44-0.54 and 0.46; 95% CI, 0.41-0.51, respectively) and increased with age. Age-standardized incidence increased over time only in men and was the highest in Norway and the Netherlands (more than 0.70). Only 1 case in 14 years was estimated to occur in Iceland vs about 20 cases per year in large countries such as France and Germany. Percentage of 5-year survival (83.5 overall; 95% CI, 78.6-87.3) was not different between adult and elderly patients but showed large geographical disparities across European regions (range, 66-89) and improved markedly in male patients (from 76 in 1995-1998 to 86 in 2003-2007, with a difference of 10.2 [95% CI, 1.3-19.2]; P < .05) becoming similar to that of women in the last period. Conclusions and Relevance Although these data are only available through 2007 and based on registries not uniformly covering the European population, the study provides the first Europe-wide estimates of the incidence and relative survival of patients with CM using population-based data. Geographical differences in survival indicate room for outcome improvement in Southern, Northern, and Eastern European countries.

Abstract
Ocular melanoma consists of posterior uveal melanoma, iris melanoma and conjunctival melanoma. These malignancies derive from melanocytes in the uveal tract or conjunctiva. The genetic profiles of these different entities differ from each other. In uveal melanoma, GNAQ and GNA11 gene mutations are frequently found and prognosis is based on mutation status of BAP1, SF3B1 and EIF1AX genes. Iris melanoma, also originating from the uvea, has similarities to the genetic makeups of both posterior uveal melanoma (UM) and conjunctival melanoma since mutations in GNAQ and GNA11 are less common and genes involved in conjunctival melanoma such as BRAF have been described. The genetic spectrum of conjunctival melanoma, however, includes frequent mutations in the BRAF, NRAS and TERT promoter genes, which are found in cutaneous melanoma as well. The BRAF status of the tumor is not correlated to prognosis, whereas the TERT promoter gene mutations are. Clinical presentation, histopathological characteristics and copy number alterations are associated with survival in ocular melanoma. Tissue material is needed to classify ocular melanoma in the different subgroups, which creates a need for the use of noninvasive techniques to prognosticate patients who underwent eye preserving treatment.

Abstract
Purpose To present the molecular mechanisms involved in the pathogenesis of conjunctival melanoma (CM) and review the existing literature on targeted molecular inhibitors as well as immune checkpoint inhibitors for the management of locally advanced and metastatic disease. Methods A comprehensive review of the literature was performed using the keywords "conjunctival melanoma", "immune checkpoint inhibitors", "BRAF inhibitors", "MEK inhibitors", "CTLA4 inhibitors", "PD1 inhibitors", "c-KIT mutations", "BRAF mutations", "NRAS mutations", "dabrafenib", "trametinib", "vemurafenib", "ipilimumab", "pembrolizumab", and "nivolumab". A total of 250 articles were reviewed and 120 were included in this report. Results Mutations of mediators in the MAP kinase pathway, such as RAS, BRAF, MEK and ERK, and mutations of the PI3K/AKT/mTOR pathway play a major role in the pathogenesis of conjunctival melanoma. In addition, alterations of c-KIT, NF1, TERT, chemokine receptors as well as chromosomal copy number alterations and micro RNAs are thought to have a causative association with CM development. Targeted molecular inhibitors, such as BRAF and MEK inhibitors, are currently being implemented in the therapy of BRAF-mutated CM. Furthermore, immune checkpoint PD-1 and CTLA4 inhibitors with favorable clinical outcomes in the treatment of cutaneous melanoma have increased recurrence-free survival and reduced metastatic spread in CM cases. Conclusion The complex molecular mechanisms that contribute to the development of CM can be targeted both by molecular inhibitors of oncogenic pathways as well as immune checkpoint inhibitors in order to halt progression of the disease and increase survival.

Abstract
The aim of this paper is to give an overview of different benign and malignant epibulbar tumors. Categories can be made of the age of manifestation (paediatric tumors versus tumors of adults), the originating cell types (squamous cell tumors, melanocytic tumors, lymphomas or germ cell tumors) or genesis (proliferative, infectious or degenerating tumors). Most epibulbar tumors show lesions on the conjunctiva or the cornea. These can be flesh coloured or pigmented efflorescences with leucoplakias or hyperkeratosis. Especially malignant tumors show atypical growth of blood vessels, are often prominent and can have ulcerations or bleeding. In case of tumor growth, change in pigmentations or atypical bleedings a malign tumor can be suspected. The diagnosis should be confirmed using histopathological evaluation after an incisional or excisional biopsy. Molecular pathologic techniques extend the diagnostic tools and have an implication on the therapy of metastatic tumors. Therapeutic options of the malignant tumors (apart from lymphomas) are chirurgical excision preferably with a no touch technique and afterwards an adjuvant therapy consisting of radiation or cryotherapy. A topical chemotherapy with Mitomycin C, 5-Fluorouracil or Interferon α2b can be effective to reduce persisting precancerosis and reduce recurrences. In case of a suspected malignant tumor it is advisable to refer the patient to an ophthalmo-oncologic center to plan and ensure interdisciplinary therapy.

Abstract
Background Dynamic N6-methyladenosine (m6A) RNA modification generated and erased by N6-methyltransferases and demethylases regulates gene expression, alternative splicing and cell fate. Ocular melanoma, comprising uveal melanoma (UM) and conjunctival melanoma (CM), is the most common primary eye tumor in adults and the 2nd most common melanoma. However, the functional role of m6A modification in ocular melanoma remains unclear. Methods m6A assays and survival analysis were used to explore decreased global m6A levels, indicating a late stage of ocular melanoma and a poor prognosis. Multiomic analysis of miCLIP-seq, RNA-seq and Label-free MS data revealed that m6A RNA modification posttranscriptionally promoted HINT2 expression. RNA immunoprecipitation (RIP)-qPCR and dual luciferase assays revealed that HINT2 mRNA specifically interacted with YTHDF1. Furthermore, polysome profiling analysis indicated a greater amount of HINT2 mRNA in the translation pool in ocular melanoma cells with higher m6A methylation. Results Here, we show that RNA methylation significantly inhibits the progression of UM and CM. Ocular melanoma samples showed decreased m6A levels, indicating a poor prognosis. Changes in global m6A modification were highly associated with tumor progression in vitro and in vivo. Mechanistically, YTHDF1 promoted the translation of methylated HINT2 mRNA, a tumor suppressor in ocular melanoma. Conclusions Our work uncovers a critical function for m6A methylation in ocular melanoma and provides additional insight into the understanding of m6A modification.

Curr Mol Med 2019; 19:632-664. [DOI: 10.2174/1566524019666190726161044] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/12/2019] [Revised: 07/12/2019] [Accepted: 07/15/2019] [Indexed: 12/17/2022]
Abstract
Over the last few years, we have seen constant development of molecular
pathology for the care of patients with cancer. The information obtained from molecular
data has transformed our thinking about the biological diversity of cancers, particularly in
the field of ophthalmic oncology. It has reoriented the way in which therapeutic decisions
and decisions concerning patient surveillance are made, both in the area of pediatric
cancers, including rhabdomyosarcoma and retinoblastoma, and adult cancers, such as
uveal melanoma and lymphomas. A better definition of the molecular classification of
these cancers and of the different biological pathways involved is essential to the
understanding of both the pathologist and the onco-ophthalmologist. Molecular tests
based on targeted or expanded analysis of gene panels are now available. These tests
can be performed with tumor tissue or biofluids (especially blood) to predict the
prognosis of tumors and, above all, the benefit of targeted therapies, immunotherapy or
even chemotherapy. Looking for the BAP1 mutation in uveal melanoma is essential
because of the associated metastatic risk. When treating retinoblastoma, it is mandatory
to assess the heritable status of RB1. Conjunctival melanoma requires investigation into
the BRAF mutation in the case of a locally advanced tumor. The understanding of
genomic alterations, the results of molecular tests and/or other biological tests predictive
of a therapeutic response, but also of the limits of these tests with respect to the
available biological resources, represents a major challenge for optimal patient
management in ophthalmic oncology. In this review, we present the current state of
knowledge concerning the different molecular alterations and therapeutic targets of
interest in ophthalmic oncology.

Abstract
PURPOSE To determine the epidemiology and survival of primary conjunctival malignant neoplasms. METHODS Retrospective analysis of primary malignant conjunctival neoplasms using Surveillance, Epidemiology, and End Results database from 1973 to 2012. RESULTS Of 1661 cases, the most common neoplasms are squamous cell carcinoma (SCC) at 54.8% and melanoma at 38.8%. Mean diagnostic age for melanoma was 62.1 compared to 65.5 years for SCC (p = 0.002). 52.2% of melanoma are male versus 77.4% of SCC (p < 0.001). For SCC only age (HR: 1.09, 95% CI:1.04-1.14) is a predictor of survival. For melanoma, age (HR: 1.07, 95% CI: 1.05-1.10), male sex (HR: 2.04, 95% CI: 1.16-3.60), T4 tumors (HR: 3.38, 95% CI: 1.17-9.80) and N1 status (HR: 8.69, 95% CI: 2.75-27.42) are all survival predictors. The 5 and 10-year overall survival (OS) estimates are not significantly different between SCC and melanoma, with 70% and 50% respectively for SCC, and 71% and 50% respectively for melanoma. Median survival time is worse for blacks (52 months) compared to whites (118 months) and Asians/Native Americans/Pacific Islanders (145 months), however race was not found to be a significant prognostic factor in multivariate analysis. Five-year survival are similar between decades 1973-1982 (66.2%), 1983-1992 (69.2%), 1993-2002 (71.3%) and 2003-2012 (70.2%). CONCLUSION Age at diagnosis is a determinant of survival for both conjunctival SCC and melanoma. Male sex, T4 and N1 staging are also important prognostic factors for melanoma. With respect to overall survival, SCC and melanoma did not differ significantly.

Abstract
The Montreal Protocol has limited increases in the UV-B (280-315 nm) radiation reaching the Earth's surface as a result of depletion of stratospheric ozone. Nevertheless, the incidence of skin cancers continues to increase in most light-skinned populations, probably due mainly to risky sun exposure behaviour. In locations with strong sun protection programs of long duration, incidence is now reducing in younger age groups. Changes in the epidemiology of UV-induced eye diseases are less clear, due to a lack of data. Exposure to UV radiation plays a role in the development of cataracts, pterygium and possibly age-related macular degeneration; these are major causes of visual impairment world-wide. Photodermatoses and phototoxic reactions to drugs are not uncommon; management of the latter includes recognition of the risks by the prescribing physician. Exposure to UV radiation has benefits for health through the production of vitamin D in the skin and modulation of immune function. The latter has benefits for skin diseases such as psoriasis and possibly for systemic autoimmune diseases such as multiple sclerosis. The health risks of sun exposure can be mitigated through appropriate sun protection, such as clothing with both good UV-blocking characteristics and adequate skin coverage, sunglasses, shade, and sunscreen. New sunscreen preparations provide protection against a broader spectrum of solar radiation, but it is not clear that this has benefits for health. Gaps in knowledge make it difficult to derive evidence-based sun protection advice that balances the risks and benefits of sun exposure.
