Asia Pac J Ophthalmol (Phila) 2024; 13:100046. [PMID: 38320655 DOI: 10.1016/j.apjo.2024.100046] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/01/2023] [Revised: 12/13/2023] [Accepted: 12/28/2023] [Indexed: 02/08/2024] Open
Abstract
PURPOSE To determine the correlation of Fitzpatrick Skin Type (FST) and iris color with tumor size (tumor thickness and basal diameter) in patients with uveal melanoma. DESIGN Retrospective Cohort METHODS: Retrospective cohort from a single ocular oncology center of 823 patients with uveal melanoma and documented FST, iris color, and tumor size. Patients were classified by FST (type I, II, and III-V) and iris color (blue, green, and brown) on the basis of external facial photography. There were no FST type VI patients. Tumor thickness was classified into small [< 3 millimeter (mm)], medium (3.1-8.0 mm), or large (> 8.0 mm), and basal diameter into small (< 10 mm), medium (10.1-15 mm) or large (> 15 mm). The correlation of FST and iris color with tumor thickness and basal diameter was evaluated using the Kruskal-Wallis H test. RESULTS The FST classification was type I (n = 92, 11%), type II (n = 643, 78%), or III-V (n = 88, 11%), and iris color was blue (n = 472, 57%), green (n = 102, 12%), or brown (n = 249, 30%). A comparison of FST revealed differences in mean tumor thickness (P = 0.04) and basal diameter (P = 0.006). Iris color showed no difference for mean tumor thickness (P = 0.41) or basal diameter (P = 0.48). There was a statistically significant difference with brown iris color relative to FST III-V for mean tumor thickness (P = 0.003) and basal diameter (P = 0.001) but no difference with blue or green iris color (P > 0.05). CONCLUSIONS Iris color alone showed no difference in tumor size, but those with brown iris color and FST type III-V demonstrated larger tumor thickness and basal diameter.

Abstract
Choroidal melanoma (CM), despite its rarity, is the most frequent intraocular malignancy. Over time, several histological variants of CM have been distinguished, including spindle A and B cell, fascicular, epithelioid and necrotic type. However, they have been progressively abandoned as having no prognostic value and currently, the American Joint Committee of Cancer (AJCC) classification identifies three CM cell types: spindle, epithelioid and mixed cell type. Other rare histological variants of CM include: (i) diffuse melanoma; (ii) clear cell; and (iii) balloon cell melanoma. Immunohistochemically, CMs are stained with Human Melanoma Black 45 (HMB45) antigen, S-100 protein, Melan-A (also known as melanoma antigen recognized by T cells 1/MART-1), melanocyte inducing transcription factor (MITF), tyrosinase, vimentin, and Sex determining region Y-Box 10 (SOX10). Several genetic and histopathological prognostic factors of CM have been reported in the literature, including epithelioid cell type, TNM staging, extraocular extension, monosomy 3 and 6p gain and loss of BAP-1 gene. The aim of this review was to summarize the histopathological, immunohistochemical and genetic features of CM, establishing “the state of the art” and providing colleagues with practical tools to promptly deal with patients affected by this rare malignant neoplasm.

Abstract
Importance Early detection of choroidal melanoma at a small tumor size is emphasized in the literature. However, there is little published information on the specific risks of plaque-irradiated small choroidal melanoma on visual acuity and metastasis. Objective To analyze outcomes of plaque radiotherapy for small choroidal melanoma 3 mm in thickness or less. Design, Setting, and Participants This retrospective noncomparative series at a tertiary referral center included 1780 consecutive patients who had received plaque radiotherapy treatment for small choroidal melanoma. Main Outcomes and Measures Visual acuity outcomes and melanoma-associated metastasis, assessed by Kaplan-Meier analyses. Results The mean (SD) patient age at melanoma diagnosis was 58 (14) years. Of 1780 patients, 908 were female (51.0%), and 1752 were white (98.4%). Visual acuity was 20/40 OU or better in 1276 of the patients (71.7%), and the mean (SD) visual acuity was 20/40 (20/50) OU (median, 20/30; range, 20/20 to counting fingers). The mean (SD) tumor basal dimension was 8.8 (2.9) mm (median, 8.0 mm; range, 2.0-20.0 mm) and mean (SD) tumor thickness was 2.6 (0.5) mm (median, 2.7; range, 0.2-3.4 mm). Mean (SD) distance to the foveola was 3.4 (3.9) mm and to the optic disc was 3.7 (3.7) mm. The Kaplan-Meier rate of visual acuity loss (≥3 Snellen lines) was 9.5% (95% CI, 8.2%-11.0%) at 1 year, 39.2% (95% CI, 36.5%-42.0%) at 5 years, and 48.9% (95% CI, 45.6%-52.3%) at 10 years, whereas poor visual acuity (≤20/200) was 7.1% (95% CI, 5.9%-8.4%) at 1 year, 38.2% (95% CI, 35.5%-41.1%) at 5 years, and 53.5% (95% CI, 50.1%-57.1%) at 10 years. Regarding melanoma-associated metastasis, the rate was 0.2% (95% CI, 0.09%-0.6%) at 1 year, 4.5% (95% CI, 3.4%-5.9%) at 5 years, and 8.8% (95% CI, 6.9%-11.1%) at 10 years. Using 1.0-mm thickness increments, the 10-year risk for metastasis was 25.0% (95% CI, 3.9%-87.2%) at 0-mm to 1.0-mm thickness, 5.9% (95% CI, 2.5%-13.5%) at 1.1-mm to 2.0-mm thickness, 8.1% (95% CI, 5.9%-11.0%) at 2.1-mm to 3.0-mm thickness, and 13.4% (95% CI, 8.7%-20.4%) at thicknesses greater than 3.0 mm. The greater relative risk (RR) for metastasis in thinnest tumors was 1.83 (95% CI, 1.09-3.07), which likely represented more aggressive diffuse (flat) melanoma. By multivariable analysis, clinical features predictive of melanoma-associated metastasis included increasing patient age (RR, 1.32 [95% CI, 1.07-1.63] per decade; P = .01), tumor diameter (RR, 1.15 [95% CI, 1.06-1.24] per mm; P < .001), tumor thickness (RR, 2.22 [95% CI, 1.22-4.05] per mm; P = .01), photopsia symptoms (RR, 2.45 [95% CI, 1.35-4.43]; P = .003), and prior treatment before plaque radiotherapy (RR, 3.31 [95% CI, 1.31-8.33]; P = .01). Conclusions and Relevance This retrospective study suggests that small choroidal melanoma treated with plaque radiotherapy has a 10-year risk for visual acuity loss of 48.9% (95% CI, 45.6%-52.3%) and a 10-risk of systemic metastasis of 8.8% (95% CI, 6.9%-11.1%). In this analysis, each millimeter of increasing thickness and diameter contributed risk for metastatic disease.

Br J Ophthalmol 2019; 105:587-592. [PMID: 31533929 DOI: 10.1136/bjophthalmol-2019-314867] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/07/2019] [Revised: 08/19/2019] [Accepted: 09/04/2019] [Indexed: 02/05/2023]
Abstract
PURPOSE To determine whether the GNAQ/11 mutation correlated with the outcome of patients with uveal melanoma (UM) when genetic heterogeneity was considered. METHODS We performed a retrospective study of sixty-seven patients with UM. The heterogeneity of GNAQ/11 was examined by using droplet digital PCR. The correlation between metastasis and heterogeneity of the GNAQ/11 mutation was analysed. Disease free survival curves were constructed using the Kaplan-Meier method, and the Wilcoxon log-rank test was used to compare the curves. RESULTS The GNAQ/11 mutation ratio was varied between each case. Among these patients, 28.35% of them harboured homogeneous mutation of GNAQ/11, 62.69% present heterogeneous mutation and 8.96% didn't present either GNAQ or GNA11 mutation. The tumour with heterogeneous mutation of GNAQ/11 has a higher metastatic rate than that with homogeneous mutation (13/29 vs 1/18, p=0.027). In Kaplan-Meier analysis, metastasis-free survival was not significantly associated with either homogeneous or heterogeneous mutation of GNAQ/11. CONCLUSION The mutation ratio of GNAQ/11 in UM was quite variable. The tumour with heterogeneous mutation of GNAQ/11 is more likely to develop a poor prognosis than that with homogeneous mutation of GNAQ/11.

Abstract
PURPOSE This study was performed to show long-term outcomes concerning metastasis rates and local recurrence rates after primary proton beam therapy in uveal melanoma with posterior extraocular extension (EOE) with the main focus on optic nerve invasion. DESIGN Retrospective case series. METHODS All patients treated with primary proton beam therapy for choroidal or ciliary body melanoma with posterior EOE between July 1998 and August 2010 were included. EOE was detected either upon sonography at primary examination or during the surgical application of tantalum clips onto the sclera. Ultrasound was performed in each patient before surgery, and if EOE was detected, a magnetic resonance imaging (MRI) scan was performed to confirm EOE. All patients with tumors exceeding 6 mm in thickness or abutting the optic disc received a 1.5 Tesla MRI scan after clip surgery. To assess EOE during follow-up, either ultrasound examinations or-if initially detected only by MRI-MRI scans were performed during follow-up. RESULTS A total of 27 patients underwent primary proton beam therapy. The EOE was separated into 3 growth types: optic nerve infiltration in 10 patients, vortex vein infiltration in 9 patients, and transscleral growth postequatorially in 8 patients. No local recurrences were found during the overall median follow-up of 80 months (11-168 months). Metastasis rates correlated with AJCC stages but not EOE volume. CONCLUSION This study shows that posterior EOE can safely be treated by proton beam therapy, even if the optic nerve is infiltrated. MRI enables safe detection of optic nerve invasion.

Abstract
Melanomas affecting different components of the uvea occur with differing frequencies and clinical presentations. Uveal melanoma is diagnosed via funduscopic exam and ancillary tests. These lesions may present with visual findings or incidental findings on physical exam. Metastasis occurs in approximately half of all patients with primary uveal melanoma. The liver is the most common site of metastasis. Enucleation was at one time considered the definitive local treatment for primary uveal melanoma, but has been largely replaced by other therapeutic procedures that aim to prevent metastasis while preserving vision. Unfortunately, metastasis of uveal melanoma almost always proves to be fatal. The current treatment of metastatic uveal melanoma is limited by the intrinsic resistance of uveal melanoma to conventional systemic therapies. Advancements in molecular biology have resulted in the identification of a number of promising prognostic and therapeutic targets. Early detection and therapy are important factors in disease survival. It is imperative that the treating physician be familiar with the clinical features of uveal melanoma and distinguish it from mimickers in order to ensure effective and timely treatment.

Abstract
The early detection of malignancy, particularly uveal melanoma, is crucial in protecting visual acuity, salvaging the eye, and preventing metastasis. Risk factors for early detection of uveal melanoma have been clearly delineated in the literature and allow identification of melanoma when it is tiny and simulates a nevus. These factors include thickness >2 mm, presence of subretinal fluid (SRF), symptoms, the orange pigment, margin near optic disc, acoustic hollowness, surrounding halo, and absence of drusen. The importance of early detection is realized when one considers melanoma thickness, as each millimeter increase in melanoma thickness imparts 5% increased risk for metastatic disease. Newer imaging modalities like enhanced depth imaging optical coherence tomography and fundus autoflouroscence facilitate in detection of SRF and orange pigment. Additional molecular biomarkers and cytological features have been identified which can predict the clinical behavior of a small melanocytic lesion. Features that suggest a poor prognosis include higher blood levels of tyrosinase m-RNA, vascular endothelial growth factor, insulin-like growth factor; monosomy 3 and gains in chromosome 8. Management of uveal melanoma includes enucleation (for large), local eye wall resection, brachytherapy, charged particle irradiation, and thermotherapy (for small to medium tumors). Although the role of a good clinical evaluation cannot be underestimated, it is advisable to evaluate the various radiological, molecular, and cytological features, to enhance the accuracy of early diagnosis and improved prognosis.

Abstract
Uveal melanoma is the most common primary malignant tumor of the eye in adults, predominantly found in Caucasians. Local tumor control of uveal melanoma is excellent, yet this malignancy is associated with relatively high mortality secondary to metastasis. Various clinical, histopathological, cytogenetic features and gene expression features help in estimating the prognosis of uveal melanoma. The clinical features associated with poor prognosis in patients with uveal melanoma include older age at presentation, male gender, larger tumor basal diameter and thickness, ciliary body location, diffuse tumor configuration, association with ocular/oculodermal melanocytosis, extraocular tumor extension, and advanced tumor staging by American Joint Committee on Cancer classification. Histopathological features suggestive of poor prognosis include epithelioid cell type, high mitotic activity, higher values of mean diameter of ten largest nucleoli, higher microvascular density, extravascular matrix patterns, tumor-infiltrating lymphocytes, tumor-infiltrating macrophages, higher expression of insulin-like growth factor-1 receptor, and higher expression of human leukocyte antigen Class I and II. Monosomy 3, 1p loss, 6q loss, and 8q and those classified as Class II by gene expression are predictive of poor prognosis of uveal melanoma. In this review, we discuss the prognostic factors of uveal melanoma. A database search was performed on PubMed, using the terms “uvea,” “iris,” “ciliary body,” “choroid,” “melanoma,” “uveal melanoma” and “prognosis,” “metastasis,” “genetic testing,” “gene expression profiling.” Relevant English language articles were extracted, reviewed, and referenced appropriately.

Abstract
Background: Brachytherapy is the most commonly used conservative treatment for the uveal melanoma. The aim of this study was to evaluate therapeutic results of Ruthenium-106 plaque brachytherapy in the management of localized uveal melanoma cases. Methods: We reviewed retrospectively the clinical records of all patients treated in our department for an uveal melanoma, undergoing Ruthenium-106 plaque brachytherapy, from January 1996 to December 2015. We focused on clinical features, therapeutic characteristics, local and distant tumor control and side effects. Results: Nineteen patients were enrolled in our study. Mean age was 56.2 years (28-79) and the sex ratio was 1.37:1 males to females. Diagnosis was made on the basis of ophthalmological clinical examination, angiography, ultrasound and/or magnetic resonance. Median tumor diameter was 9.7 mm (6-13) and median thickness 4.4 mm (2.5-8). The dose of Ruthenium-106 plaque brachytherapy prescribed to the apex of each tumor was 70 Gy in all cases. The median radiation dose to the sclera surface was 226.4 Gy (range: 179.6–342.3) and the median total application time 115.2 hours (range: 27 to 237). After a median follow-up of 61.5 months, local control was achieved in 17 patients (89%): 16 demonstrated a partial tumor response and 1 tumor stabilization. Two patients suffered local progression leading to enucleation, one dying of hepatic metastasis. Radiation-induced complications were cataracts in 3 cases and vitreal hemorrhage in 2. Conclusion: Ruthenium-106 plaque brachytherapy is an efficient treatment for localized uveal melanoma, offering good local control with low toxicity.

Abstract
This article explores the range of tumor specimens that may be submitted to ophthalmic pathology. The handling of complex enucleation and exenteration is described along with smaller eyelid, conjunctival and corneal specimens. The importance of a good understanding of the unique anatomy of the ocular region and detailed clinical information is emphasized as this results in the taking of appropriate blocks for histology and consequently clinically helpful reports. Recommendations for handling specimens where further tissue is required for molecular studies is discussed.

Abstract
PURPOSE Small choroidal melanomas have a better prognosis than large tumours. However, these small tumours can spread, often late in their course. The aim of the study was to analyse survival and tumour characteristics of six cases of late metastatic diseases after conservative treatment. METHODS A retrospective study was conducted at the Croix-Rousse University Hospital of Lyon among 523 patients treated between 1991 and 2010 by proton beam therapy (508) or brachytherapy with 106 (Ru/Rh) (15) for uveal melanomas. We have selected patients with small choroidal melanoma (thickness≤3 mm and diameter≤9 mm) (59 patients), who have developed hepatic metastases (six of 59). RESULTS At the time of diagnosis, median age was 57 years (range, 37-82 years). The mean tumour thickness was 2.9 mm (range 2.5-3 mm), and the mean diameter was 7 mm (5-8 mm). Orange pigment was observed in four cases, subretinal fluid was observed in two cases, and one tumour touched the optic disc. Five patients had proton beam therapy. One patient had beta brachytherapy (106 Ru/106 Rh). Average follow-up was 8.3 years (range 4.2-11.8 years). None of the six patients developed local tumour recurrence. The mean survival time after diagnosis of melanoma was 9.8 years (range, 4.9-14.6 years). The average time from treatment of primary tumour to detection of liver metastasis was 7 years (range 3.9-12 years). The mean survival time from the diagnosis of metastasis was 35.2 months (range 9-101 months). Small melanoma-related death was 0% at 3 years, 1.7% at 5 years, 5.1% at 10 years and 10.2% at 15 years in our series. CONCLUSIONS Despite a small tumoral size and an early and effective local treatment, six of 59 small choroidal melanomas have developed metastasis after local treatment. Small tumours represent a significant risk of metastasis.

Abstract
Melanoma of the eye can involve the uveal tract with iris, ciliary body, or choroid involvement or it can involve the conjunctiva, eyelid, or orbit. Uveal involvement with choroidal melanoma is the most common, found in light complexion Caucasians with an age-adjusted incidence of 4.3 per million persons. Early detection of uveal melanoma is critical. The ABCDEF guide helps to differentiate iris nevus from iris melanoma. The letters represent: A, age young (≤40 years); B, blood in anterior chamber; C, clock hour of mass inferiorly; D, diffuse configuration; E, ectropion; and F, feathery margins. The mnemonic of TFSOM-UHHD (To Find Small Ocular Melanoma-Using Helpful Hints Daily) helps to differentiate choroidal nevus from small melanoma and represents: T, thickness over 2 mm; F, fluid; S, symptoms; O, orange pigment; M, margin within 3 mm of the optic disc; UH, ultrasound hollow; H, halo absent; and D, drusen absent. Patients with 3 or more of these factors are likely to have melanoma. These key clinical features help to identify small melanoma at a time when therapy could be life-saving. Conjunctival melanoma usually arises from primary acquired melanosis, a flat pigmentation that can lead to melanoma. Wide excision using no touch strategy is important to tumor control. Ocular examination is advised annually for all persons for detection of refractive error, cataract, glaucoma, and other conditions, but also for the detection of asymptomatic malignancies like melanoma. One at a time, we have uncovered the secrets of ocular melanoma and we forge ahead with the goal to solve the riddle of this challenging disease.

Abstract
PURPOSE OF REVIEW To review the current features and classification of choroidal melanoma, and to identify the lesions that clinically simulate choroidal melanoma (pseudomelanoma). RECENT FINDINGS Uveal melanoma is a serious life-threatening intraocular malignancy, most often found in Caucasians (98%) and primarily involving the choroid (90%), ciliary body (7%), or iris (2%). This review will concentrate on choroidal melanoma. At diagnosis, choroidal melanoma usually appears as a pigmented (85%) tumor underlying the retina with a median basal dimension of 11 mm and a mean thickness of 4.5 mm. The American Joint Committee on Cancer classification allows for categorization and staging of melanoma. Following ocular therapy, adjuvant systemic therapy is provided for patients with high-risk melanoma who demonstrate alterations in chromosomes 3, 6, and 8 or those with class 2 on gene-expression profiling, detected by needle biopsy or solid tumor biopsy. The prognosis of choroidal melanoma depends most importantly on the genetic alterations and tumor size. Every millimeter increase in thickness leads to a 5% increased risk for metastasis. The leading conditions that simulate choroidal melanoma include choroidal nevus, peripheral exudative hemorrhagic chorioretinopathy, congenital hypertrophy of the retinal pigment epithelium (RPE), hemorrhagic RPE detachment, choroidal hemangioma, age-related macular degeneration, RPE hyperplasia, and others. These pseudomelanomas can be differentiated from choroidal melanoma by their unique clinical features. SUMMARY Choroidal melanoma is a serious malignancy with characteristic features. Early detection and therapy is important. Pseudomelanomas can lead to diagnostic confusion; however, clinical features aid in differentiation.
