Choroidal Nevi in Children: Size, Growth, and Topographic Distribution. Am J Ophthalmol 2024:S0002-9394(24)00222-8. [PMID: 38762092 DOI: 10.1016/j.ajo.2024.05.021] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/31/2023] [Revised: 05/13/2024] [Accepted: 05/13/2024] [Indexed: 05/20/2024]
Abstract
PURPOSE To explore size, growth, and topographic distribution of choroidal nevi in children to gain insights into choroidal nevogenesis. DESIGN Retrospective consecutive case series using pediatric clinic - and population - study data, comparing to adult data. METHODS Clinical data from Cole Eye Institute (CEI) database (December 2005-January 2023) was derived from a retrospective consecutive case series of 20 children (< 20 years) with choroidal nevi. For population data, 48 children from previously reported pooled data of the participants of Sydney Pediatric Eye Disease Study, Sydney Myopia Study, Sydney Childhood Eye Study, and Sydney Adolescent Vascular and Eye Disease Study were included. Fundus photographs were reviewed and the locations of 18 choroidal nevi seen at CEI with widefield imaging were mapped on a radial scatter plot. For comparison, 100 consecutive adults with choroidal nevi were identified from CEI database. Main outcomes were size, growth, and topographic distribution of choroidal nevi. RESULTS The median largest basal diameter was 1.6 mm (range 0.4-4.2) in children. Most choroidal nevi (75%) remained stable, and 16% demonstrated growth at follow-up. The mean growth rate was calculated as 0.12 mm/year (range 0.10-0.15). Malignant transformation was not noted during childhood. All secondary changes (drusen, orange pigment, and subretinal fluid) associated with choroidal nevi in children were less common than those in adults (p<0.05). Choroidal nevi in children were located significantly more posterior than in adults. The median distance to fovea was 2.1 mm (range 0.5-8.5) in children and 5.1 mm (range 0.4-16) in adults (p<0.0001). CONCLUSIONS The onset and growth of choroidal nevi in children suggest active choroidal nevogenesis in childhood. A posterior topographic distribution may support the developmental framework for migration and maturation of choroidal melanoblasts.

Advanced intraocular retinoblastoma: evolving criteria for group E disease. CANADIAN JOURNAL OF OPHTHALMOLOGY 2024:S0008-4182(24)00068-1. [PMID: 38688458 DOI: 10.1016/j.jcjo.2024.03.005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/29/2024] [Revised: 02/28/2024] [Accepted: 03/12/2024] [Indexed: 05/02/2024]
Abstract
With evolving criteria for classifying intraocular retinoblastoma (RB) from International Intraocular Retinoblastoma Classification (IIRC, 2005) to International Classification of Retinoblastoma (ICRB, 2006), there have been changes in the inclusion criteria for groups E eyes that have not been widely recognized. This brief review highlights issues with the current classification systems (ICRB and IIRC) and layouts a theoretical framework arguing for merging of 2 existing classifications into 1 and subdividing the expanded group E RB, thereby preserving the possibility to reanalyze existing published data.

Impression cytology of ocular surface in xeroderma pigmentosum. Arq Bras Oftalmol 2024; 87:e2023. [PMID: 38656021 DOI: 10.5935/0004-2749.2023-0026] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/23/2023] [Accepted: 08/21/2023] [Indexed: 04/26/2024] Open
Abstract
PURPOSE To describe cellular alterations detected by impression cytology of the ocular surface in patients with xeroderma pigmentosum. The secondary objective was to assess the reliability of impression cytology in diagnosing ocular surface squamous neoplasia. METHODS Patients with xeroderma pigmentosum underwent a single-day complete ophthalmological examination and impression cytology for ocular surface evaluation using 13 mm diameter mixed cellulose esters membrane filters and combined staining with Periodic Acid Schiff, Hematoxylin and Eosin, and Papanicolaou stains followed by microscopic analysis. The cytological findings were correlated with the clinical diagnosis. The impression cytology findings at baseline and one-year follow-up were correlated with the clinical course (no tumor, treated tumor, residual tumor recurrent tumor, new tumor). RESULTS Of the 42 patients examined, impression cytology was performed in 62 eyes of 34 participants (65% females). The mean age of patients was 29.6 ± 17 years (range 7-62). Fifteen eyes had a clinical diagnosis of ocular surface squamous neoplasia. Impression cytology showed goblet cells (47, 75%), inflammatory cells (12, 19%), keratinization (5, 8%), and squamous metaplasia (30, 48%). Impression cytology was positive for atypical cells in 18 patients (12 with and 6 without ocular surface squamous neoplasia). The sensitivity, specificity, positive predictive value, and negative predictive value of impression cytology (at baseline) for diagnosis of ocular surface squamous neoplasia were 80%, 87%, 67%, and 93%, respectively, using clinical diagnosis of ocular surface squamous neoplasia as the reference standard. CONCLUSION Impression cytology has a moderate positive predictive value for the diagnosis of ocular surface squamous neoplasia in patients with xeroderma pigmentosum. However, the lack of detection of atypical cells on impression cytology has a high negative predictive value for ocular surface squamous neoplasia. Integration of impression cytology in the long-term management of high-risk patients, such as patients with xeroderma pigmentosum, can avoid unnecessary diagnostic biopsies.

Abstract
Introduction We aim to explore the safety and efficacy of episcleral brachytherapy as a primary management option for eyes with retinal pigment epithelial (RPE) adenoma. Methods Retrospective chart review of the demographic, clinical, ancillary, and postoperative outcome data of patients with RPE adenoma in 2 tertiary referral centers. Tumor regression, final visual acuity, and complications were assessed. Results Five patients (3 females and 2 males) were included. Four of the 5 eyes had peripheral and mid-peripheral lesions, while one tumor was juxtapapillary. Three eyes were treated with ruthenium-106 (100 Gray), and 2 received iodine-125 episcleral plaques (85 Gray). All eyes showed clinical and imaging-based evidence of regression. Four eyes had stable or improved visual acuity, while 1 eye exhibited one line loss of visual acuity due to radiation retinopathy. Local recurrence was not observed in any eye over a median follow-up of 24 (range 6-112) months. Conclusions Episcleral brachytherapy is an effective management option for select cases of RPE adenoma that is capable of achieving tumor regression while maintaining favorable visual acuity. The initial safety profile of brachytherapy is good without significant vision-compromising complications.

Abstract
PURPOSE To assess Meibomian gland dysfunction using meibography in patients with xeroderma pigmentosum and correlate with ocular surface changes. METHODS This cross-sectional study evaluated patients with xeroderma pigmentosum. All patients underwent a comprehensive and standardized interview. The best-corrected visual acuity of each eye was determined. Detailed ophthalmic examination was conducted, including biomicroscopy examination of the ocular surface, Schirmer test type I, and meibography, and fundus examination was also performed when possible. Meibomian gland dysfunction was assessed by non-contact meibography using Oculus Keratograph® 5M (OCULUS Inc., Arlington, WA, USA). Saliva samples were collected using the Oragene DNA Self-collection kit (DNA Genotek Inc., Ottawa, Canada), and DNA was extracted as recommended by the manufacturer. Factors associated with abnormal meiboscores were assessed using generalized estimating equation models. RESULTS A total of 42 participants were enrolled, and 27 patients underwent meibography. The meiboscore was abnormal in the upper eyelid in 8 (29.6%) patients and in the lower eyelid in 17 (62.9%). The likelihood of having abnormal meiboscores in the lower eyelid was 16.3 times greater than that in the upper eyelid. In the final multivariate model, age (p=0.001), mutation profile (p=0.006), and presence of ocular surface malignant tumor (OSMT) (p=0.014) remained significant for abnormal meiboscores. For a 1-year increase in age, the likelihood of abnormal meiboscores increased by 12%. Eyes with OSMT were 58.8 times more likely to have abnormal meiboscores than eyes without ocular surface malignant tumor. CONCLUSION In the final model, age, xeroderma pigmentosum profile, previous cancer, and clinical alterations on the eyelid correlated with a meiboscore of ≥2. Meibomian gland dysfunction was common in patients with xeroderma pigmentosum, mainly in the lower eyelid. The severity of Meibomian gland dysfunction increases with age and is associated with severe eyelid changes.

Surveillance for Metastasis in High-Risk Uveal Melanoma Patients: Standard versus Enhanced Protocols. Cancers (Basel) 2023; 15:5025. [PMID: 37894391 PMCID: PMC10605386 DOI: 10.3390/cancers15205025] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/21/2023] [Revised: 10/04/2023] [Accepted: 10/13/2023] [Indexed: 10/29/2023] Open
Abstract
PURPOSE to evaluate the effectiveness of enhanced surveillance protocols (EP) utilizing high frequency (HF) or enhanced modality (EM) compared to the standard protocol (SP) in detecting metastasis and determining their impact on overall survival (OS) in high-risk uveal melanoma (UM) patients. METHODS A total of 87 consecutive patients with Class 2 (high risk) primary UM were enrolled, with negative baseline systemic staging. The patients underwent systemic surveillance with either SP (hepatic ultrasonography [US] every 6 months) or EP (either HF [US every 3 months] or EM [incorporation hepatic computed tomography/magnetic resonance imaging]) following informed discussion. The main outcome measures were largest diameter of largest hepatic metastasis (LDLM), number of hepatic metastatic lesions, time to detection of metastasis (TDM), and OS. RESULTS This study revealed significant differences in LDLM between surveillance protocols, with the use of EP detecting smaller metastatic lesions (HF, EM, and SP were 1.5 cm, 1.6 cm, and 6.1 cm, respectively). Patients on the EM protocol had a lower 24-month cumulative incidence of >3 cm metastasis (3.5% EM vs. 39% SP; p = 0.021), while those on the HF protocol had a higher 24-month cumulative incidence of ≤3 cm metastasis compared to SP (31% HF vs. 10% SP; p = 0.017). Hazard of death following metastasis was significantly reduced in the EP (HR: 0.25; 95% CI: 0.07, 0.84), HF (HR: 0.23; 95% CI: 0.06, 0.84), and EM (HR: 0.11; 95% CI: 0.02, 0.5) groups compared to SP. However, TDM and OS did not significantly differ between protocols. CONCLUSIONS Enhanced surveillance protocols improved early detection of hepatic metastasis in UM patients but did not translate into a survival advantage in our study cohort. However, early detection of metastasis in patients receiving liver-directed therapies may lead to improved overall survival.

Abstract
Uveal melanoma prognostication studies have mainly included posterior uveal melanomas located in the ciliary body and choroid, often excluding iris melanoma. In this study, we report prognostic status and survival outcomes in a series of 35 patients with biopsy-proven iris melanoma. Fluorescence in situ hybridization was performed in 10 (29%) cases and 2 (5%) underwent multiplex ligation-dependent probe amplification. In total, 9 cases demonstrated disomy 3, 2 cases with monosomy 3 (fluorescence in situ hybridization), and 1 had a technical failure. On gene expression profile testing, 20 of the 23 cases (90%) were gene expression profile class 1A, and the remaining 3 (10%) were class 1B. No patient had a Class 2 status. The median follow-up period was 49 months (mean 59, range 2-156 months). No metastasis was reported during follow-up, and metastasis-free survival was 100%. A review of the published literature revealed 47 cases with high-risk status on molecular prediction, of which only 6 (13%) developed metastasis. Ciliary body involvement was reported in 5 cases and was unknown in 2 cases. We conclude that molecular prognostication of iris melanoma demonstrates low-risk prognostic status in the majority of cases irrespective of the technique used. Even those with high-risk status do not develop metastasis unless the tumor involves the ciliary body.

Abstract
PURPOSE To determine if a greater than expected number of cases (clustering) of uveal melanoma occurred within Ohio for any specific region or time period as compared to others. DESIGN Analysis of population database. METHODS Ohio Cancer Incidence Surveillance System (OCISS) database (2000-2019) was accessed for the diagnosis of uveal melanoma using the International Classification of Disease for Oncology codes: C69.3 (choroid), C69.4 (ciliary body and iris). Counties within Ohio were grouped by geographic regions (7) and socioeconomic variables. Age- and race-standardized incidence ratios (SIR) were calculated to determine temporal or geographic clustering. RESULTS Over the twenty-year period, the total number of uveal melanoma cases reported within Ohio were 1,617 with the overall age-adjusted annual incidence of 6.72 cases per million population (95% CI 6.30-7.16). There was an increase in the incidence of uveal melanoma over 20 years (p<0.001) across seven geographic regions, but no significant difference in incidence rates between the regions. There was no difference in incidence based on county classification by age composition (p = 0.14) or education level (p = 0.11). Counties with a low median household income (p<0.001), those classified as urban (p = 0.004), and those with a greater minority population (p = 0.004) had lower incidence. Less populated counties had a higher incidence of uveal melanoma (p<0.001). CONCLUSIONS There is no evidence of geographic or temporal clustering of uveal melanoma within Ohio from 2000 to 2019.

Abstract
Introduction Determining the nature of iris melanocytic tumors based on clinical exam alone remains challenging. Tumor-associated vasculature of iris melanocytic lesions may facilitate the ability to discern between iris nevus and melanoma. Methods In a single-institution, retrospective, observational study of 45 patients with pathologically confirmed iris melanoma and 15 patients with iris nevi that were either clinically stable or pathologically confirmed were included. Tumor characteristics and associated vasculature were identified on clinical exam and slit-lamp photographs. Fluorescein angiographic parameters including feeder vessels, intrinsic vessels, leakage, masking, and angiographic silence were assessed. Results Feeder vessels were present in 17 (43%) melanomas and were absent in the nevus group (p = 0.002). Thirty-three (83%) iris melanomas and 5 (33%) iris nevi were observed to have intrinsic vessels, and a statistically significant association of intrinsic vessels with malignancy (p = 0.001) was noted. Fluorescein leakage was also observed more frequently in iris melanoma 39 (98%) than in nevi 9 (60) with a significant difference (p = 0.001). Angiographic silence occurred in 3 nevi (20%) and was not observed in any melanoma (p = 0.017). Overall, the presence of intrinsic vessels +/- feeder vessels had high sensitivity (0.85) and high positive predictive value (0.87) for diagnosis of iris melanoma. Conclusions Anterior segment fluorescein angiography allows for the assessment of tumor-associated vascular patterns and demonstrates utility in differentiating iris nevi from melanoma. Feeder vessels were only observed in iris melanoma and were absent in iris nevi. The intrinsic vessels were present more frequently in melanomas and are thus associated with malignancy. Angiographic silence is indicative of iris nevi.

Abstract
PURPOSE To assess the efficacy of a 0.18 mg intravitreal fluocinolone acetonide (FA) implant (Yutiq, EyePoint Pharmaceuticals, Watertown, MA) as a treatment option for patients with radiation retinopathy-related cystoid macular edema. METHODS A retrospective review of seven patients treated for uveal melanoma who developed radiation retinopathy-related cystoid macular edema. They were initially treated with intravitreal anti-vascular endothelial growth factor and/or steroid injections and then transitioned to intravitreal FA implant. Primary outcomes include best-corrected visual acuity, central subfield thickness, and number of additional injections. RESULTS After FA implant insertion, best-corrected visual acuity and central subfield thickness remained stable in all patients. The variance in best-corrected visual acuity decreased from 75.5 ETDRS letters (range 0-199 letters) to 29.8 (range 1.2-134) after FA implant insertion. Mean central subfield thickness was 384 µ m (range 165-641) and 354 µ m (range 282-493) before and after FA implant insertion, resulting in a 30- µ m mean reduction. The number of intravitreal injections (average 4.9, range 2-10) decreased after intravitreal FA implant insertion with only two patients requiring one additional FA implant (average 0.29, range 0-1) over a mean of 12.1 months (range 0.9-18.5) follow-up. CONCLUSION Intravitreal FA implant is an effective treatment for cystoid macular edema radiation retinopathy. The slow release of steroid allows for sustained control of macular edema, which correlated with stable visual acuity and decreased injection burden for patients.

Abstract
Introduction Peripheral exudative hemorrhagic chorioretinopathy (PEHCR) is one of the leading mimickers of choroidal melanoma because of overlapping features with choroidal melanoma that make the distinction between these two entities difficult. Methods To identify nonoverlapping diagnostic features between PEHCR and choroidal melanoma, a retrospective study of 80 patients (80 eyes); 40 patients (40 eyes) with PEHCR; and 40 patients (40 eyes) with choroidal melanoma was conducted. Ophthalmoscopic and imaging features of PEHCR and choroidal melanoma were compared. Sensitivity and specificity for identifying PEHCR and choroidal melanoma were calculated. Youden's J statistic was assessed for each diagnostic feature. Results The most frequent clinical features of PEHCR were presence of druse (100%), hemorrhagic PED (93%), dome-shaped mass (B-scan) (90%), and subretinal/intraretinal hemorrhage (78%). Statistical analysis confirmed high sensitivity of hemorrhagic PED (0.93; 95% CI 0.80-0.98) and high specificity of clot retraction cleft, presence of lipid exudation, and bilaterality (1.00; 95% CI 0.91-1.00) as diagnostic features of PEHCR. Statistical analysis revealed presence of subretinal fluid 0.80 (95% CI 0.54-0.91) was most sensitive and presence of orange pigment, mushroom shape on B-scan, ciliary body extension, and choroidal excavation were most specific (1.00; 95% CI 0.91-1.00) for choroidal melanoma. Nonoverlapping diagnostic features of PEHCR were hemorrhagic PED, clot retraction cleft, presence of lipid exudation, and bilaterality. All PEHCR patients (100%) had at least one of these nonoverlapping diagnostic features. Nonoverlapping diagnostic features of choroidal melanoma were the presence of orange pigment, choroidal excavation, mushroom-shaped mass, and ciliary body extension (the latter 3 detected on B-scan). Youden's J statistic was highest for hemorrhagic PED and lowest for dome-shape appearance on B-scan (0.075). Conclusion PEHCR and choroidal melanoma can be differentiated by identifying diagnostic features that are exclusive to each entity. The presence of hemorrhagic PED strongly supports a diagnosis of PEHCR. B-scan ultrasonography is required to detect a mushroom-shaped mass, choroidal excavation, or ciliary body extension to exclude underlying choroidal melanoma.

Abstract
Uveal melanoma (UM) is uncommon in African Americans. Owing to its rarity, UM may not be suspected in African Americans leading to delayed diagnosis. In addition, socioeconomic factors may also play a role in delayed diagnosis. Clinical and ultrasonographic features may be atypical due to racial pigmentation, necessitating diagnostic fine needle aspiration biopsy. Herein, we report an illustrative case series of 12 African Americans with UM highlighting clinical features and diagnostic challenges.

Abstract
GLI1-altered mesenchymal tumors are an emerging entity in soft tissue pathology. In the head and neck region, they are most commonly in the tongue. Limited published data indicate a propensity for local recurrence, regional spread, and distant metastasis in both GLI1-rearranged and GLI1-amplified tumors. The purpose of this report is to present the rare case of a GLI1-amplified spindle cell tumor of the orbit and a focused review of the literature. A 54-year-old woman presented with proptosis, eye pain, and ocular motility restriction in the left eye. Imaging demonstrated a tumor occupying the superomedial intraconal orbit that was distinct from the extraocular muscles, optic nerve, and globe. The tumor was totally resected with a combined open transorbital and endoscopic, endonasal approach. Pathological analysis demonstrated a spindled and epithelioid mesenchymal tumor with diffuse nuclear GLI1 expression. PCR-based, next*-generation sarcoma fusion panel was negative for GLI1 fusions, including GLI1::ACTB fusions; however, DDIT3 breaks apart fluorescence in situ hybridization (FISH), which can be used as a surrogate for GLI1 alterations due to proximity to 12q13.3, showing amplification. Post-operatively, the patient had recovered visual acuity. She received adjuvant radiation therapy (60 Gy in 30 fractions). Surveillance for recurrence, regional spread, and distant metastasis has been negative at a 6-month follow-up. Ultimately, we report the first case of a GLI1-amplified mesenchymal neoplasm of the intraconal orbit managed with gross total resection via a combined approach followed by adjuvant radiation therapy.

Anterior Uveal Melanocytoma: Role of Diagnostic FNAB. Ocul Oncol Pathol 2023; 8:211-220. [PMID: 36925727 PMCID: PMC10013327 DOI: 10.1159/000527596] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/08/2022] [Accepted: 09/28/2022] [Indexed: 11/19/2022] Open
Abstract
Introduction Anterior uveal melanocytoma (AUM) pose a diagnostic challenge as they can mimic growing melanomas. Establishing a definitive diagnosis of melanocytoma necessitates cytologic or histopathologic confirmation. We describe the clinical presentation and characteristics of fifteen pathologically proven AUM cases and assess the role of fine needle aspiration biopsy (FNAB) as a safe and effective tool for diagnosis. Methods Retrospective review of pathologically confirmed AUM cases was performed. Demographic data, presenting symptoms, clinical features, diagnostic approach, cytological and histological features, and clinical outcomes were collected. Results Fifteen patients with pathologically confirmed AUM were identified. The mean and median age of diagnosis were 50 and 53 years, respectively (range 3-77 years). The melanocytoma was localized to the iris (5, 33%) or ciliary body (7, 47%), and 3 patients had iridociliary involvement (20%). Presentation was due to concern for growth in 4 (29%), visual symptoms in 1 (7%), and was an incidental finding in 10 (64%) patients. Pigmentation of the tumor varied with 9 (60%) appearing brown and 3 (20%) black in color. The color of 3 (20%) ciliary body tumors could not be assessed. The diagnosis was confirmed with FNAB in 6 (40%), excisional biopsy in 7 (47%), and incisional biopsy in 2 (13%). Cytologic and histologic preparations demonstrated predominance of round to polygonal cells with heavily pigmented cytoplasm and small round nuclei. One patient who underwent excisional biopsy had prior FNAB that was interpreted as suspicious for melanoma (false-positive). Instances of false-negative cytology were not observed as demonstrated by the subsequent stable clinical course during the mean follow-up of 21.2 months (range = 1.0-63.0 months). FNAB-related complications were not observed in any case. Conclusion FNAB offers a minimally invasive and safe diagnostic approach for pathologic confirmation of AUM. However, limitations of FNAB including false-negative and false-positive biopsies must be considered when excluding underlying malignancy. Continued observation to document tumor stability should be considered.

Emerging New Therapeutics for Retinoblastoma. Ocul Oncol Pathol 2022; 8:149-155. [PMID: 36938374 PMCID: PMC10015589 DOI: 10.1159/000524919] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/28/2022] [Accepted: 04/27/2022] [Indexed: 11/19/2022] Open
Abstract
Background: Over the last few decades, chemotherapy has become the main treatment of retinoblastoma, delivered through various routes: intravenous, intra-arterial, and intravitreal. Despite its efficacy, chemotherapy-related toxicity (ocular and systemic) and recurrences due to resistant tumor clones are common, highlighting the need for novel therapeutic agents. Summary: Recent advances in our understanding of the molecular drivers of Rb1 tumorigenesis and mechanisms of tumor resistance have afforded opportunities to explore novel targets such as the MDMX-p53 pathway (nutlin-3), histone deacetylase inhibitors, spleen tyrosine kinase inhibitors, and genetic and immune modulatory drugs. In this review, we discuss the limitations of current therapeutic strategies, candidate cellular pathways, current evidence for newer targeted drugs, and offer a look toward the future. Key Messages: Advances in the understanding of the molecular drivers of the RB pathway have provided opportunities to explore novel drugs with targeted effects, improved bioavailability, and reduced chemotoxicity.

Abstract
Importance Accuracy of the predicted metastasis-free survival (MFS) by a commercially available gene expression profiling (GEP) test is not known. Objective To compare the predicted MFS with the observed MFS in patients in this cohort and with those in published studies (published MFS, meta-analysis). Design, Setting, and Participants This cohort study included consecutive patients from the University of Iowa and Cleveland Clinic who were diagnosed with uveal melanoma who underwent prognostic fine-needle aspiration biopsy at the time of primary treatment. Patients were recruited from December 2012 to December 2020. The predicted MFS for patients was extracted from the GEP report. The observed MFS was defined as time to metastasis. Cox proportional hazards models were fit to identify tumor variables impacting MFS in patients with class 2 tumors. The overall estimate of the published MFS was obtained by performing meta-analysis of data from published series. Analysis took place in August 2021. Main Outcomes and Measures MFS. Results There were 92 patients from the University of Iowa and 255 patients from the Cleveland Clinic. The mean (SD) age at diagnosis was 59.4 (13.0) years. The median (IQR) follow-up interval was 38.0 (19.0-57.0) months. The observed MFS for patients with class 2 tumor in this cohort (3 years: 67% [95% CI, 59%-77%]; 5 years: 47% [95% CI, 37%-61%]) and in published studies (3 years: 62% [95% CI, 57%-66%]; 5 years: 40% [95% CI, 34%-46%]) were better than those predicted (50% and 28% for 3 and 5 years, respectively). Within patients with class 2 tumor, those with metastasis had larger tumors compared with nonmetastatic tumors (mean largest basal diameter difference, 1.7 [95% CI, 0.5-3.0] mm; P = .01; mean thickness ratio, 1.3 [95% CI, 1.04-1.5]; P = .01, respectively). An increasing tumor size was significantly associated with increased hazard ratio (1.16 [95% CI, 1.06-1.27]; P < .001) of metastasis. Conclusions and Relevance These findings suggest the predicted MFS for metastatic tumors (class 2) appears to be worse than that observed here and reported by others. Incorporation of tumor size in the prediction model may enhance its accuracy. Adjuvant therapy trials may not be able to rely on predicted MFS to calculate efficacy with a high degree of confidence.

The Global Retinoblastoma Outcome Study: a prospective, cluster-based analysis of 4064 patients from 149 countries. THE LANCET GLOBAL HEALTH 2022; 10:e1128-e1140. [PMID: 35839812 PMCID: PMC9397647 DOI: 10.1016/s2214-109x(22)00250-9] [Citation(s) in RCA: 19] [Impact Index Per Article: 9.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/05/2022] [Revised: 05/06/2022] [Accepted: 05/23/2022] [Indexed: 02/01/2023] Open
Abstract
Background Retinoblastoma is the most common intraocular cancer worldwide. There is some evidence to suggest that major differences exist in treatment outcomes for children with retinoblastoma from different regions, but these differences have not been assessed on a global scale. We aimed to report 3-year outcomes for children with retinoblastoma globally and to investigate factors associated with survival. Methods We did a prospective cluster-based analysis of treatment-naive patients with retinoblastoma who were diagnosed between Jan 1, 2017, and Dec 31, 2017, then treated and followed up for 3 years. Patients were recruited from 260 specialised treatment centres worldwide. Data were obtained from participating centres on primary and additional treatments, duration of follow-up, metastasis, eye globe salvage, and survival outcome. We analysed time to death and time to enucleation with Cox regression models. Findings The cohort included 4064 children from 149 countries. The median age at diagnosis was 23·2 months (IQR 11·0–36·5). Extraocular tumour spread (cT4 of the cTNMH classification) at diagnosis was reported in five (0·8%) of 636 children from high-income countries, 55 (5·4%) of 1027 children from upper-middle-income countries, 342 (19·7%) of 1738 children from lower-middle-income countries, and 196 (42·9%) of 457 children from low-income countries. Enucleation surgery was available for all children and intravenous chemotherapy was available for 4014 (98·8%) of 4064 children. The 3-year survival rate was 99·5% (95% CI 98·8–100·0) for children from high-income countries, 91·2% (89·5–93·0) for children from upper-middle-income countries, 80·3% (78·3–82·3) for children from lower-middle-income countries, and 57·3% (52·1-63·0) for children from low-income countries. On analysis, independent factors for worse survival were residence in low-income countries compared to high-income countries (hazard ratio 16·67; 95% CI 4·76–50·00), cT4 advanced tumour compared to cT1 (8·98; 4·44–18·18), and older age at diagnosis in children up to 3 years (1·38 per year; 1·23–1·56). For children aged 3–7 years, the mortality risk decreased slightly (p=0·0104 for the change in slope). Interpretation This study, estimated to include approximately half of all new retinoblastoma cases worldwide in 2017, shows profound inequity in survival of children depending on the national income level of their country of residence. In high-income countries, death from retinoblastoma is rare, whereas in low-income countries estimated 3-year survival is just over 50%. Although essential treatments are available in nearly all countries, early diagnosis and treatment in low-income countries are key to improving survival outcomes.

Aqueous humor as a surrogate biomarker for retinoblastoma tumor tissue. J AAPOS 2022; 26:137.e1-137.e5.

Abstract
PURPOSE To demonstrate the feasibility of identifying a germline RB1 pathogenic variant in retinoblastoma (RB) from an aqueous humor (AH) sample. METHODS In this pilot case series, peripheral blood, fresh tumor tissue, and AH were obtained from 3 eyes of 3 RB patients who underwent enucleation at a tertiary eye care institute. After isolation of the cell-free DNA (cfDNA), sequence analysis of the RB1 core promoter and of exons 1 through 27, including nearby flanking intronic regions, was performed using a custom targeted hybridization protocol, followed by high-throughput sequencing. RESULTS The study cohort included 3 enucleated eyes with advanced RB (group E [n = 2], group D [n = 1]). In case 1, deletion of the RB1 promoter to exon 23 (delP->23) on both alleles was identified from tumor as well as AH samples and absent in the blood sample, indicative of absence of a germline RB1 pathogenic variant. In case 2, two heterozygous RB1 nonsense variants, c.610G>T p.(Glu204Ter) and c.751C>T p.(Arg251Ter), were identified in tumor and AH samples (allele frequency of 49% and 45%, resp.) and were absent in the blood sample, indicative of absence of a germline RB1 pathogenic variant. In case 3, a heterozygous c.2326-14T>A substitution on allele 1 and loss of heterozygosity on allele 2 were identified in the tumor and AH (allele frequency of 97%), with the same heterozygous mutation in the blood sample, indicating presence of a germline RB1 pathogenic variant. CONCLUSIONS The pathogenic RB1 variant results from AH in all 3 eyes were concordant with direct tumor DNA sampling, suggesting that AH can serve as a surrogate for tumor tissue. Because the AH can be accessed during treatment, specific testing can be performed even in the absence of enucleation.

Abstract
PURPOSE To quantify potential loss (loss of vision) and gain (freedom from metastasis) in patients with small choroidal melanoma treated after a period of surveillance to document growth. METHODS A total of 167 patients with small choroidal melanoma (size: 5.0-16.0 mm in largest basal diameter and 1.0-2.5 mm in height) were identified: 42 treated after surveillance (documented growth) and 125 treated immediately. A prediction model was applied to each patient in the immediate treatment group to obtain the predicted risk of melanoma (high risk vs low risk). Potential loss (loss of vision) and gain (freedom from metastasis) were compared between the low-risk immediate treatment group and those treated after surveillance. RESULTS By using the optimal cut point (0.60; 95% confidence interval: 0.37-0.61) of predicted risk for small choroidal melanoma (sensitivity: 0.74, specificity: 0.95), we identified 94 (75%) patients as high risk (score: ≥0.6) and the remaining 31 (25%) as having low-risk melanoma (score: <0.6). Over a median follow-up of 34.6 months, 5 developed metastasis (high risk = 4, low risk = 1) compared with 1 patient in the surveillance group. Initial visual acuity and loss of <15-letter visual acuity were not significantly different at 36 months between the low-risk patients immediately treated and those treated after surveillance (81% vs 83%), respectively. CONCLUSIONS Low-risk choroidal melanoma identified by the prediction model can be labeled as an indeterminate melanocytic tumor. Such patients can be managed by surveillance to document growth before receiving vision-threatening treatment without increased risk of metastatic death.

Abstract
Objective This study aimed to develop a validated machine learning model to diagnose small choroidal melanoma. Design This is a cohort study. Subjects Participants and/or Controls The training data included 123 patients diagnosed as small choroidal melanocytic tumor (5.0-16.0 mm in largest basal diameter and 1.0 mm-2.5 mm in height; Collaborative Ocular Melanoma Study criteria). Those diagnosed as melanoma (n = 61) had either documented growth or pathologic confirmation. Sixty-two patients with stable lesions classified as choroidal nevus were used as negative controls. The external validation dataset included 240 patients managed at a different tertiary clinic, also with small choroidal melanocytic tumor, observed for malignant growth. Methods In the training data, lasso logistic regression was used to select variables for inclusion in the final model for the association with melanoma versus choroidal nevus. Internal and external validation was performed to assess model performance. Main Outcome Measures The main outcome measure is the predicted probability of small choroidal melanoma. Results Distance to optic disc ≥3 mm and drusen were associated with decreased odds of melanoma, whereas male versus female sex, increased height, subretinal fluid, and orange pigment were associated with increased odds of choroidal melanoma. The area under the receiver operating characteristic "discrimination value" for this model was 0.880. The top four variables that were most frequently selected for inclusion in the model on internal validation, implying their importance as predictors of melanoma, were subretinal fluid, height, distance to optic disc, and orange pigment. When tested against the validation data, the prediction model could distinguish between choroidal nevus and melanoma with a high discrimination of 0.861. The final prediction model was converted into an online calculator to generate predicted probability of melanoma. Conclusions To minimize diagnostic uncertainty, a machine learning-based diagnostic prediction calculator can be readily applied for decision-making and counseling patients with small choroidal melanoma.

Abstract
Purpose The aim of the study was to evaluate equivalence of growth rate and pathologic confirmation in small choroidal melanoma (SCM). Design This study is a case series. Subjects Participants and Controls A total of 61 patients with a choroidal melanocytic tumor of size 5.0-16.0 mm in the largest basal diameter and 1.0-2.5 mm in thickness were classified into the pathology-confirmed group (n = 19), growth-confirmed group (n = 30), and with combined observations (n = 12). Methods Distribution of clinical variables (age, gender, laterality, tumor dimensions, tumor location, and presence of orange pigment, subretinal fluid, drusen, and retinal pigment epithelial [RPE] atrophy) between the groups was analyzed. Patient and disease characteristics were summarized as the median and interquartile range for continuous variables and the frequency and percentage for categorical variables. Comparisons were made using the Wilcoxon rank sum test for continuous variables and either Fisher's exact test or the χ2 test for categorical variables with a p value threshold of 0.05 for statistical significance. Growth rate (change in basal dimension/12 months) diagnostic of SCM was quantified. Main Outcome Measures The primary aim of this study was to test the hypothesis that "growth" was diagnostic of SCM with the secondary aim of quantifying the malignant "growth rate" (growth rate of SCM). Results The clinical characteristics among all 3 groups were similar except more patients with symptoms (68 vs. 20 vs. 42%, p = 0.004) and juxtapapillary location (p = 0.03) were in the pathology group than in the growth-confirmed group. Those in the combined and growth-confirmed groups had more patients with drusen (11 vs. 60 vs. 50%, p = 0.003) and RPE atrophy (11 vs. 23 vs. 67%, p = 0.003), respectively, than in the pathology group. The median time to detect growth was 9 months (range 3-26 months). The mean growth rate in basal dimension was 1.8 mm/12 months (range, 0.0-7.4 mm; [95% CI: 1.32-2.28]). Conclusions and Relevance Choroidal melanocytic lesions exhibiting a defined growth rate can be clinically diagnosed as SCM without a need for biopsy.

Abstract
Background Hodgkin lymphoma (HL) is a hematopoietic neoplasm characterized by cancerous Reed-Sternberg cells. In contrast to ophthalmic manifestations by non-HL that are well recognized, there is paucity of the literature as it relates to ophthalmic manifestation by HL. We performed a comprehensive review of published studies (case reports and small case series) to characterize the ophthalmic manifestations of HL. Summary Thirty patients were identified with ophthalmic manifestation of HL. Thirteen (43%) were male, and 14 (46%) were female (in 3 cases, sex was not specified). The median age at ophthalmic presentation was 27 years. Diagnosis of HL was made after ophthalmic manifestation in 10 (33%) cases, whereas 11 (36%) cases had a prior diagnosis of HL. Ophthalmic manifestations can be classified into 3 main groups; direct infiltration, inflammatory reaction, and paraneoplastic process. Seven cases had infiltration of the optic nerve. Uveal inflammatory reaction was reported in 21 cases. The presence of intraocular Reed-Sternberg cells had been confirmed in 1 case with granulomatous uveitis. Conjunctival and corneal reaction was seen in 3 cases. HL was in stage 2 or higher, with only 1 case with stage 1A (12 cases HL stage not specified). Seven cases (22%) died of HD, all were diagnosed with advanced lymphoma, and none was treated with chemotherapy. Key Message Ocular involvement in HL is extremely rare. A few cases of histopathologically confirmed optic nerve/tract infiltration are within the spectrum of CNS involvement by HL. Inflammatory uveitis is the most common ophthalmic association of HL. In the presence of prior known diagnosis of HL, restaging should be considered to exclude recurrence. Toxicity or adverse reaction to drugs used to treat HL may also contribute to ophthalmic involvement.

Abstract
PURPOSE To investigate prevalence and age of onset of choroidal melanocytic lesions (other than nevi) in pediatric patients. METHODS The pooled data of participants 6 months to 18 years of age in the Sydney Paediatric Eye Disease Study, the Sydney Myopia Study, and the Sydney Adolescent Vascular Eye Disease Study were reviewed retrospectively to identify children with choroidal melanocytic lesions. The clinical features and prevalence by age were assessed. RESULTS From the pooled sample of 5,533 unique children, 39 cases of focal melanocytic aggregates and 22 cases of choroidal melanocytosis were identified, with overall prevalence of 0.70% and 0.40%, respectively. There was a statistically significant trend toward increased prevalence with increasing age. Both focal melanocytic aggregates and choroidal melanocytosis tended to be bilateral (100% and 86% respectively), brown in color, and temporally located in all cases. Amelanotic variants were not identified. Focal melanocytic aggregates were small (0.15-0.5 mm), whereas choroidal melanocytosis varied in size (5.0-20 mm). All focal melanocytic aggregates were characteristically located 4-5 mm temporal to the center of the fovea and were associated with linear nervelike (11 [28%]) or tortuous vessel like structures (10 [26%]). CONCLUSIONS In this study, pooled data from large population studies revealed morphologic patterns of choroidal melanocytic lesions, other than nevus, that correlate with described clinical appearance in adults. The association of focal melanocytic aggregates with nervelike structures supports their embryologic origin along the migration path of uveal melanocytes.

Abstract
IMPORTANCE Diagnosis of small choroidal melanoma is based upon clinical features and presence of factors predictive of local malignant growth. Prognostic biopsy quantifies risk of metastasis. OBJECTIVE The aim of this study is to explore relationship between clinical characteristics and metastatic potential of a small choroidal melanoma. DESIGN Retrospective review of 53 patients with small choroidal melanoma treated in a tertiary oncology clinic. Patients were derived from 3 cohorts, with pathologic confirmation, with growth confirmation, and those treated only on clinical basis. Based upon prognostic biopsy outcomes, each case was classified into low or high metastatic potential groups. Distribution of clinical characteristics such as age, laterality, symptoms, tumor dimensions, tumor distance from optic nerve and fovea, presence of surface orange pigment, drusen, retinal pigment epithelial atrophy, and subretinal fluid was analyzed between metastatic groups. MAIN OUTCOME MEASURES Distribution of clinical characteristics between low or high metastatic potential groups was analyzed. RESULTS A total of 53 patients [mean age, 61 years (range, 27-81 years); 32 (60%) men and 21 (40%) women] were classified into pathology confirmed group (n = 13), growth confirmed group (n = 26), and with clinical group (n = 14). Prognostic biopsy in the growth, pathology, and clinical groups revealed low metastatic potential in 23, 10, and 11 patients, respectively, and high metastatic potential in 3 patients in each group. Distribution of clinical characteristics between low or high metastatic potential groups was not statistically significantly different. CONCLUSION Clinical characteristics do not identify metastatic potential of a small choroidal melanoma.

Abstract
Purpose This study aimed to explore factors for refusing treatment in patients diagnosed with uveal melanoma and their subsequent clinical course. Methods This study included patients with uveal melanoma who refused standard of care treatment. Patient-reported reasons and pre-existing mental health diagnoses were assessed. The sociodemographic profile was compared with the controls. Ocular survival, metastasis-free survival (MFS), and overall survival (OS) were calculated. Results Nine patients with uveal melanoma declined ocular treatment (plaque brachytherapy, n = 7 [78%]; enucleation, n = 2 [22%]). The choroidal melanomas were small (n = 1 [11%]), medium (n = 5 [56%]), and large (n = 3 [33%]) in size (COMS criteria). The sociodemographic profile of the study patients was not different from those that accepted treatment. One patient (11%) had pre-existing mental health diagnosis. Five patients (56%) eventually accepted treatment following an average delay of 19 months (range: 4-55 months) due to neovascular glaucoma or severe vision loss. MFS could not be ascertained, and OS was 67% (6/9) at 4.2 years of follow-up (mean). Conclusions Refusal of initial recommended treatment is associated with poor ocular survival. The small sample size did not allow for an evaluation of the impact on survival.

Abstract
Uveal melanoma (UM) and renal cell carcinoma (RCC) can occur sporadically and as a manifestation of BAP1 tumor predisposition syndrome. We aimed to understand the prevalence of germ line BAP1 pathogenic variants in patients with UM and RCC. We reviewed patients managed at Cleveland Clinic between November 2003 and November 2019 who were diagnosed with UM and RCC. Charts were reviewed for demographic and cancer-related characteristics. RCC samples were tested for BAP1 protein expression using immunohistochemical (IHC) staining, and testing for germ line BAP1 pathogenic variants was performed as part of routine clinical care. Thirteen patients were included in the study. The average age at diagnosis of UM was 61.3 years. Seven patients underwent fine-needle aspiration biopsy for prognostic testing of UM (low risk =5, high risk =2). Twelve patients were treated with plaque radiation therapy, and 3 patients developed metastatic disease requiring systemic therapy. The median time to diagnosis of RCC from time of diagnosis of UM was 0 months. RCC samples were available for 7 patients for BAP1 IHC staining (intact =6, loss =1). All patients underwent nephrectomy (total = 3, partial = 8, unknown =2), and 1 received systemic therapy for metastatic RCC. Six patients underwent germ line BAP1 genetic testing. Of these, 1 patient was heterozygous for a pathogenic variant of BAP1 gene: c.1781-1782delGG, p.Gly594Valfs*48. The overall prevalence of germ line BAP1 pathogenic variants in our study was high (1/6; 17%; 95% CI 0-46%). Patients with UM and RCC should be referred for genetic counseling to discuss genetic testing.

Estrogen Receptor Is Expressed in Uveal Melanoma: A Potential Target for Therapy. Ocul Oncol Pathol 2021; 7:303-310. [PMID: 34604204 DOI: 10.1159/000512174] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/16/2020] [Accepted: 10/08/2020] [Indexed: 12/22/2022] Open
Abstract
Background Metastatic uveal melanoma (UM) has no effective treatment. To date, no publications have reported immunohistochemical evidence of estrogen receptors (ERs) in UM; however, changes in pathologic reporting for ER in breast carcinoma prompted a re-examination of ER in UM, as it could represent a potential therapeutic target. Objective To determine if UM tumors express ER by immunohistochemistry (IHC) using current methodology for breast cancer and to evaluate ER gene expression using a publicly available UM database. Methods A retrospective IHC analysis with clinical correlation was performed on 2 cohorts: 57 cases from the Cleveland Clinic (CC) and 50 from the Ohio State University Wexner Medical Center (OSUWMC). Analysis of The Cancer Genome Atlas Project (TCGA) UM Dataset of 80 patients was also performed. Results Presence of ER was detected by IHC in 20 of 34 (59%) analyzable cases in the CC cohort. Of the 50 patients in the OSU cohort, 52 specimens from 47 patients were sufficient for analysis. Of these 47 cases, 29 (62%) had tumor that was ER positive in ≥1% nuclei. In the second cohort, positivity was classified as positive (≥10% nuclei, 34% cases) or low positive (1-9% nuclei, 28% cases). In 5 patients, there were paired samples, that is, primary tumor and subsequent recurrence or metastasis, with concordance for ER in 4 of 5 cases. In the TCGA database, elevated ESR1 and ESR2 gene expression was identified in a subset of UM tumors with poor genetic prognostic features. Conclusions and Relevance Potentially actionable ER expression is present in greater than half of UM cases by IHC. Gene expression of ESR1 and ESR2 was elevated in a subset of UM tumors with poor prognostic features. These data provide a rationale to evaluate ER as a potential target for therapy in UM.

Choroidal nevi in children: prevalence, age of onset, and progression. J AAPOS 2021; 25:225.e1-225.e6. [PMID: 34271212 DOI: 10.1016/j.jaapos.2021.03.012] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/20/2020] [Revised: 03/08/2021] [Accepted: 03/16/2021] [Indexed: 11/19/2022]
Abstract
PURPOSE To determine the age of onset and prevalence of choroidal nevi in children. METHODS In this cross-sectional study, the fundus photographs of a pooled sample of children 6 months to 18 years of age with 6-year longitudinal follow-up who participated in the Sydney Paediatric Eye Disease Study, Sydney Myopia Study, and the Sydney Adolescent Vascular Eye Disease Study were reviewed. Prevalence by age, clinical features, and longitudinal follow-up assessment was undertaken. RESULTS Of 5,533 children (7,059 examinations), 48 children with a choroidal nevus were identified. Prevalence increased with age: <6 years, 0.47%; 6 years, 0.63%; 12 years, 1.06%; 18 years, 1.79%. Nevus was unilateral in all cases (100%), and the majority were melanotic (46, 96%). Most (36 [75%]) were irregular in shape, with ill-defined margins (45 [94%]). All identified nevi were posterior to the equator. All nevi were small, with the average largest basal diameter of 1.6 mm (range, 0.5-3.2) and were not associated with secondary changes (drusen, orange pigment, subretinal fluid). The majority (18/31 [58%]) of nevi remained stable, with 5 of 31 (16%) demonstrating subtle growth (minimum of 600 μm). Four new-onset nevi were documented. Malignant transformation was not observed in any of the nevi. CONCLUSIONS In our study cohort, the prevalence of choroidal nevi increased with age up to 18 years. The distribution and prevalence of choroidal melanocytic lesions reported herein can be used for designing population-based studies in children that incorporate emerging imaging technologies.

Abstract
There are various hypotheses for the anatomic origin of a choroidal macrovessel. We assess whether a choroidal macrovessel is a dilated posterior ciliary artery. A systematic review of published literature on choroidal macrovessels was performed with two additional cases from our institution. We compared the visible entry and vascular course of the macrovessel in the published literature. We performed a comparative analysis using indocyanine green angiography, swept source optical computed tomography, and 3D reconstruction of two choroidal macrovessels using 3D Slicer (Harvard, Boston, USA, https://www.slicer.org/). From the 14 studies found, 18 cases met inclusion criteria. The reported literature and our two cases showed a radiating course along a sectoral distribution pattern of either short or long posterior ciliary arteries. Our review of literature and 3D reconstruction analysis support the hypothesis that choroidal macrovessels are dilated posterior ciliary arteries.

Abstract
Multiple myeloma (MM) remains an incurable disease with the majority of patients experiencing disease relapse despite response to initial therapy. Antibody-drug conjugates (ADCs) and bispecific T-cell engagers are innovative immunotherapeutic approaches currently in development for the treatment of MM. This systematic review summarizes the efficacy and safety of ADCs and bispecific T-cell engagers in relapsed refractory (RR) MM patients from 2010 to date. Comprehensive literature search was conducted on PubMed, EMBASE, Wiley Cochrane Library, Web of Science, and Clinicaltrials.gov . A total of 13 studies (n = 529) met inclusion eligibility. All studies were prospective in nature investigating ADCs or bispecific T-cell engagers in RR MM; 10 trials were phase 1 and 3 were phase 2. The median age of patients ranged from 24 to 82 years. Among trials with ADC regimens, the overall response (OR) ranged from 34 to 60% and complete response (CR) ranged from 3 to 6%. The most common non-hematologic adverse event (AE) of ADCs was keratopathy, while anemia and thrombocytopenia were the most common hematological AEs. With bispecific T-cell engagers , ORR ranged from 31 to 83%, CR ranged from 7 to 22%, and partial response (PR) ranged from 5 to 16%. The most common non-hematologic AE of bispecific T-cell engagers was cytokine release syndrome (CRS) while the most common hematological AE was neutropenia. Initial data appears to show good clinical activity and tolerable safety profiles, making ADCs and bispecific T-cell engagers promising agents for RRMM. Future studies with newer combinations and a longer follow-up are needed to determine the precise role of these novel therapies in the evolving paradigm of MM treatment.

Outcomes for posterior uveal melanoma: Validation of American Brachytherapy Society Guidelines. Brachytherapy 2021; 20:1226-1234. [PMID: 34305017 DOI: 10.1016/j.brachy.2021.05.165] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/06/2021] [Revised: 05/26/2021] [Accepted: 05/27/2021] [Indexed: 11/27/2022]
Abstract
PURPOSE To assess outcomes of small and medium choroidal melanoma (less than 5.0 mm in height) following Iodine-125 episcleral brachytherapy. METHODS AND MATERIALS Patients with small and medium choroidal melanoma that underwent Iodine-125 brachytherapy with apical height of 1.0 mm to 5.0 mm and largest basal diameter of ≤16.0 mm were included. Data were extracted from the original dosimetry plans to determine doses to vision critical structures with the prescription point to the apical height (actual dose, ABS guidelines) and, after simulation, with the prescription point to the height of 5.0 mm (simulated dose, COMS protocol). Visual acuity (VA) outcomes with actual dose and that predicted with the simulated dose were estimated along with local recurrence, ocular survival, and survival at 5 years. RESULTS A total of 339 patients with a mean age of 61.5 years with a mean follow up duration of 43.4 months were included. The mean dose reduction for lens, optic disc, and fovea was 34%, 39.4%, and 41.4%, respectively with actual dose when compared with simulated dose. The Kaplan-Meier estimations for 3 year event free rate of VA of 20/50 or better were 56% and 31% for actual dose and simulated dose, respectively. Only 3 events of local recurrence were observed (enucleated) yielding 5 year local control and ocular survival rate of 98%. Overall survival (OS) and metastasis free survival (MFS) were 95% and 87.5% at 5 years, respectively. CONCLUSIONS Small and medium choroidal melanoma treated according to ABS has excellent outcomes. Brachytherapy planning using ABS guidelines as compared to COMS protocol may be associated with lower rates of radiation toxicity and vision loss.

Abstract
Purpose: The objective of this study was to identify the diagnostic features of optic nerve head melanocytoma (ONH-MCT) on spectral domain optical coherence tomography (SD OCT) and OCT angiography (OCT-A). Methods: Retrospective study of 11 patients for their demographic, clinical features and imaging including SD OCT (tumour location, extent and interface) and OCT-A (surface and intrinsic vascularity) were reviewed. Flow rate percentage (FR %) was calculated over the lesion and compared to fellow eye and similar pigmented lesions. Results: The average age was 52.8 ± 10.9 years. ONH-MCT tumors occupied 3-tissue spaces- optic disc (n = 2), retinal layer (n = 5) and retina-choroidal layers (n = 4). SD OCT (11 eyes) showed elevated hyper reflective disorganized retinal layers with posterior shadowing (9 eyes) and hyper reflective dots within the tumor (all eyes). Microvascular features on OCT-A (8 eyes) in radial peripapillary capillary slab showed surface vascularization (7 eyes) and intrinsic vascularity in choroidal slab (8 eyes) with surrounding hypo reflective boundary. The mean FR % was higher at 65.1 ± 3.77% (CI: 61.9-68.2) compared to mean FR at 60.4 ± 1.06% (CI: 59.5-61.2) in the fellow eye (p = 0.01). Comparison with nevus and melanoma SD OCT showed a high reflective choroidal layer with normal or irregular outer retinal layers respectively; OCT-A showed hypo reflective area at the center with hyper reflective boundary and iso reflective area at center with hyper reflective boundary respectively. Conclusion: SD OCT and OCT-A features may help to differentiate ONH-MCT from clinically similar looking pigmented lesions like nevus and melanoma.

Abstract
Purpose The long-term survival of uveal melanoma patients in the US is not known. We compared long-term survival estimates using relative survival, excess absolute risk (EAR), Kaplan-Meier (KM), and competing risk analyses. Setting Population based cohort study. Study population Pooled databases from Surveillance, Epidemiology, and End Results data (SEER, SEER-9+SEER-13+SEER-18). Main outcome measure Overall Survival (OS), Metastasis Free Survival (MFS) and relative survival, computed directly or estimated via a model fitted to excess mortality. Results There were 10678 cases of uveal melanoma spanning a period of 42 years (1975–2016). The median age at diagnosis was 63 years (range 3–99). Over half the patients were still alive at the end of 2016 (53%, 5625). The KM estimates of MFS were 0.729 (0.719, 0.74), 0.648 (0.633, 0.663), and 0.616 (0.596, 0.636) at 10, 20, and 30 years, respectively. The cumulative probabilities of melanoma metastatic death at 10, 20 and 30 years were 0.241 (0.236, 0.245), 0.289 (0.283, 0.294), and 0.301 (0.295, 0.307). In the first 5 years since diagnosis of uveal melanoma, the proportion of deaths attributable to uveal melanoma were 1.3 with rapid fall after 10 years. Death due to melanoma were rare beyond 20 years. Relative survival (RS) plateaued to ~60% across 20 to 30 years. EAR parametric modeling yielded a survival probability of 57%. Conclusions Relative survival methods can be used to estimate long term survival of uveal melanoma patients without knowing the exact cause of death. RS and EAR provide more realistic estimates as they compare the survival to that of a normal matched population. Death due to melanoma were rare beyond 20 years with normal life expectancy reached at 25 years after primary therapy.

Abstract
Importance The extent to which uveal melanoma is cured by ocular therapy is not known. Objective To estimate cured fractions (CF) of uveal melanoma using combination of institutional and Surveillance, Epidemiology, and End Results (SEER) data. Design, Setting, and Participants Integrative analysis of 42 years of SEER data (1975-2016) with 25 years (1993-2018) of complementary institutional data. The analysis included SEER US patients and molecularly prognosticated patients in the United States and Europe. Three SEER databases (SEER-9, SEER-13, and SEER-18) were merged. A total of 10 678 SEER cases of uveal melanoma diagnosed from 1975 to 2016 using International Classification of Disease for Oncology morphology codes 8720-8790 (for melanoma) and site codes C69.2-4 (for choroid, ciliary body, and iris) were downloaded April 16, 2019. The institutional data included 5 institutional cohorts of 788 molecularly prognosticated patients (diagnosed prior to July 2019) with 3115 person-years at risk of death and 262 observed deaths. Main Outcomes and Measures Excess absolute risks of death (EAR) and cured fraction (CF) indicates lifetime area under the EAR curve. These are applied to populations and subpopulations. Results The SEER EAR, with sexes and races pooled, can be modeled as a sum of 2 waves. The first wave peaks at approximately 3 years and is negligible by 15 years, at which time the second wave peaks. Institutional data suggest that the first wave is owing to BAP1 mutant cases (204 of 355 [57.5%]; 95% CI, 52%-63%) and that the second wave is owing to BAP1 wild-type SF3B1 mutant cases (60 of 355 [17%]; 95% CI, 13%-21%). There is also a third group with a low flat EAR time course (91 of 355 [25.5%]; 95% CI, 21%-30%). The overall statistical CF of 60% is reached by approximately 25 years. Conclusions and Relevance These findings suggest that the benefits of ocular therapy for curing uveal melanoma may be questionable because statistical cures reflect deaths of poor prognosis cases and survival of good prognosis cases. Changes in uveal melanoma patient management may be needed to improve survival.

Abstract
PURPOSE To estimate point prevalence of uveal melanoma in the patients with germline BAP1 pathogenic variant. DESIGN Cohort study with risk assessment using Bayesian analysis. METHODS The point prevalence estimate was obtained by Bayes's rule of reverse conditional probabilities. The probability of uveal melanoma given that BAP1 mutation exists was derived from the prevalence of uveal melanoma, prevalence of germline BAP1 pathogenic variants, and the probability of germline BAP1 pathogenic variant given that uveal melanoma is present. Confidence intervals (CIs) for each variable were calculated as the mean of Bernoulli random variables and for the risk estimate, by the delta method. The age at diagnosis and the gender of the uveal melanoma patients with BAP1 germline pathogenic variants obtained from previous publications or from authors' unpublished cohort was compared with those in the Surveillance, Epidemiology, and End Results (SEER) database. RESULTS The point prevalence of uveal melanoma in patients with the germline BAP1 pathogenic variants in the US population was estimated to be 2.8% (95% CI, 0.88%-4.81%). In the SEER database, the median age at diagnosis of uveal melanomas was 63 (range 3-99 years) with a male-to-female ratio of 1.01:1. In comparison, uveal melanoma cases with BAP1 germline pathogenic variants from the US population (n = 27) had a median age at diagnosis of 50.5 years (range 16-71). CONCLUSIONS Quantification of the risk of developing uveal melanoma can enhance counseling regarding surveillance in patients with germline BAP1 pathogenic variant.

Abstract
Primary central nervous system lymphoma-ophthalmic variant (PCNSL-O) is an ocular subset of PCNSL predominantly involving subretinal pigment epithelium space, retina, and vitreous. The ophthalmic manifestations can precede, occur simultaneously, or follow other compartments of the CNS. Clinical trials have resulted in a significantly improved outcome in PCNSL patients over the past 2 decades, with a higher proportion of patients receiving frontline high dose methotrexate-based polychemotherapy regimens with curative intent; however, the current management of PCNSL-O remains controversial owing to lack of prospective data. The goals of PCNSL-O treatment are both to achieve local (ocular) control and to prevent tumor-specific mortality from further CNS involvement. Despite achieving high rates of ocular control with intravitreal agents like methotrexate and rituximab, the overall survival is poor, as 65-85% of patients eventually succumb to CNS disease. Few studies define the role of systemic chemotherapy with/without local treatment as a first line induction treatment for PCNSL-O considering limiting factors such as ocular penetration of systemically administered drugs and treatment related neurotoxicity. Also, the role of adjuvant treatment for PCNSL-O to prevent CNS progression and to improve overall survival is unknown. In this systematic review of the literature, we analyze treatment outcomes of various regimens (local, systemic, and combination) in terms of local control, CNS progression, and overall survival.

Abstract
Despite limited data, some differences in the clinical profile can be observed in Asian population when compared with presentation of uveal melanoma (UM) in white population. The incidence of UM is higher in Whites than in Asians. For the purpose of comparison with Asian population, data from North America, Europe, and Australia were considered as that of "white" population. The annual incidence of UM has been reported to be 5-6 cases/million in whites. The incidence in different parts of Asia is estimated at 0.2-0.6 per million. The age of presentation is around 40-55 years in Asians, which is younger when compared to that of whites (mean age of 58 years). At presentation, mean basal diameter of tumors in Asians is greater compared to whites but overall, medium-size tumors are most common. Clinical presentation is straightforward in majority of cases with retinal detachment, acute glaucoma, uveitis, cataract, or vitreous hemorrhage as common symptoms. Epithelioid cell-type variant carries the worst prognosis. Management options for choroidal melanoma include transpupillary thermotherapy, plaque radiotherapy, charged particle irradiation, local resection, enucleation, or orbital exenteration. Most commonly used modalities are enucleation and plaque radiotherapy.

Abstract
OBJECTIVE To analyse ocular and systemic findings of patients presenting with systemic metastasis. METHODS AND ANALYSIS It is an international, multicentre, internet-enabled, registry-based retrospective data analysis. Patients were diagnosed between 2001 and 2011. Data included: primary tumour dimensions, extrascleral extension, ciliary body involvement, American Joint Committee on Cancer (AJCC)-tumour, node, metastasis staging, characteristics of metastases. RESULTS Of 3610 patients with uveal melanoma, 69 (1.9%; 95% CI 1.5 to 2.4) presented with clinical metastasis (stage IV). These melanomas originated in the iris, ciliary body and choroid in 4%, 16% and 80% of eyes, respectively. Using eighth edition AJCC, 8 (11%), 20 (29%), 24 (35%), and 17 (25%) belonged to AJCC T-categories T1-T4. Risk of synchronous metastases increased from 0.7% (T1) to 1.5% (T2), 2.6% (T3) and 7.9% (T4). Regional lymph node metastases (N1a) were detected in 9 (13%) patients of whom 6 (67%) had extrascleral extension. Stage of systemic metastases (known for 40 (59%) stage IV patients) revealed 14 (35%), 25 (63%) and 1 (2%) had small (M1a), medium-sized (M1b) and large-sized (M1c) metastases, respectively. Location of metastases in stage IV patients were liver (91%), lung (16%), bone (9%), brain (6%), subcutaneous tissue (4%) and others (5%). Multiple sites of metastases were noted in 24%. Compared with the 98.1% of patients who did not present with metastases, those with synchronous metastases had larger intraocular tumours, more frequent extrascleral extension, ciliary body involvement and thus a higher AJCC T-category. CONCLUSIONS Though higher AJCC T-stage was associated with risk for metastases at diagnosis, even small T1 tumours were stage IV at initial presentation. The liver was the most common site of metastases; however, frequent multiorgan involvement supports initial whole-body staging.

Photodynamic therapy for choroidal melanoma: What is the response rate? Surv Ophthalmol 2021; 66:552-559. [PMID: 33400941 DOI: 10.1016/j.survophthal.2020.09.006] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/06/2020] [Revised: 09/20/2020] [Accepted: 09/21/2020] [Indexed: 02/03/2023]
Abstract
To determine the response rate of choroidal melanoma following primary photodynamic therapy, we conducted a meta-analysis of published studies. A total of 7 studies reporting photodynamic therapy as primary treatment of choroidal melanoma in 162 patients with a mean tumor height of 2.8 mm (1.4 to 4.2) were identified. Forty-six percent of tumors were amelanotic, 48% were fully pigmented, and 6% had partial pigmentation. The photodynamic therapy parameters in all studies included 10-minute intravenous infusion of verteporfin (6 mg/m2), but varied in number of sessions (1 to 3), fluence (1× to 19×), and number of spots (single or multiple). The response was defined as tumor regression (partial or total) or lack of growth after initial treatment. The response to photodynamic therapy was predominantly observed as regression (126 [78%]). Overall response rate was 80% (mean) with a wide range among studies (58%-100%) over a period of 50 months (mean) with variable follow-up (range, 1-156 months). None of the studies reported progression- or recurrence-free survival; however, the recurrence rate was not related to the follow-up duration. Favorable prognostic factors were smaller size and lack of pigmentation. The overall response rate of 80% suggests that photodynamic therapy may be an effective primary treatment for small choroidal melanoma, especially in cases without pigmentation. Artifacts in study design (inclusion criteria and outcome measure) may have contributed to the variable observed response rate. Further studies with uniform inclusion criteria, standardized treatment parameters, well-defined outcome measures, and long follow-up are needed.

Immunotherapy-Resistant Vitreoretinal Metastatic Melanoma. Ocul Oncol Pathol 2020; 7:62-65. [PMID: 33796519 DOI: 10.1159/000511187] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/19/2019] [Accepted: 08/21/2020] [Indexed: 11/19/2022] Open
Abstract
Purpose To describe 2 cases of vitreoretinal metastases in patients treated with immunotherapy for metastatic melanoma. Methods Retrospective case series. Results We pre-sent 2 patients with metastatic melanoma treated with systemic immunotherapy with subsequent development of ocular vitreoretinal metastasis. The first patient was a male with metastatic melanoma from a site of unknown origin that was in complete remission following a course of ipilimumab and nivolumab therapy. He presented to an outside provider for evaluation of vitritis and a pigmented lesion in the right eye that was presumed secondary to toxoplasmosis. After failing initial management with oral antibiotics, he underwent diagnostic pars plana vitrectomy, and vitreous biopsy was consistent with metastatic melanoma to the vitreous. He was additionally found to have an elevated pigmented retinal mass consistent with a retinal metastasis from melanoma that initially failed treatment with plaque brachytherapy and ultimately required enucleation. The second case was a monocular male with metastatic melanoma from cutaneous melanoma with decreased vision 3 months after the initiation of nivolumab therapy. He presented with dense vitreous debris in his seeing eye and was thought to have nivolumab-associated inflammation. He was initially treated with difluprednate with improved vision and decrease in vitreous debris, but developed dense pigment deposition in the affected eye later in the treatment course. Diagnostic pars plana vitrectomy was performed, and vitreous biopsy was positive for malignant melanoma cells. His systemic disease was in remission at the time of diagnosis of ocular metastasis. External beam radiation was recommended given his monocular status. Conclusion Vitreoretinal metastasis can develop despite favorable systemic response to immunotherapy in patients with metastatic cutaneous melanoma. Lack of ocular penetration and extension of life span with immunotherapeutic agents may be the underlying mechanism for vitreoretinal metastasis.

Patient-Reported Complications after Intravitreal Injection and Their Predictive Factors. Ophthalmol Retina 2020; 5:625-632. [PMID: 33059077 PMCID: PMC7548755 DOI: 10.1016/j.oret.2020.09.024] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/08/2020] [Revised: 09/17/2020] [Accepted: 09/29/2020] [Indexed: 12/27/2022]
Abstract
Purpose The intravitreal injection (IVI) of pharmacologic agents is the most commonly performed ocular procedure and is associated with a host of complications. Most IVI-related complications data are derived from randomized controlled clinical trials, which report a high adverse event rate. The nature of these protocol-driven trials limit their applicability to the diverse circumstances seen in routine clinical practice. The goal of this study was to determine the prevalence of patient-reported IVI-related complications, their risk factors, and the manner in which patients sought treatment at a tertiary eye care center. Design Retrospective, institutional review board–approved study. Participants Forty-four thousand seven hundred thirty-four injections in 5318 unique patients at the Cleveland Clinic Cole Eye Institute from 2012 through 2016. Methods Intravitreal injection. Main Outcome Measures Complication occurrence within 15 days of injection. Results From 2012 through 2016, a total of 44734 injections were performed in 5318 unique patients. Overall, complication rates were low, representing 1.9% of all injections, with 1031 unique complications in 685 patients (12.9%). The most common minor complications, or those not requiring intervention, were irritation (n = 312) and subconjunctival hemorrhage (n = 284). The most common serious complications, or those requiring intervention, were corneal abrasion (n = 46) and iritis (n = 31). Most complications (66%) were managed adequately by a telephone or Epic (Epic Systems Corp., Verona, WI) electronic message encounter only. Importantly, no injection protocol parameter, such as type of anesthesia, preparation, or post-injection medication, increased the risk of a complication. However, a patient’s gender, age, number of previous injections, and provider strongly influenced the risk of patient-reported complications. Conclusions Overall, complication rates seen in routine clinical practice were low compared with clinical trial reporting. Providers should feel confident in the safety and administration of IVI during times when follow-up office visits and resources may be limited. When performing an IVI, factors such as a patient’s gender, age, number of previous injections, and provider must be taken into account to ensure the best possible outcomes.
