Iris melanoma: factors predictive of post-management secondary glaucoma in 271 cases at a Single Ocular Oncology Centre.

BACKGROUND/AIMS: To identify factors predictive of post-management secondary glaucoma in eyes with iris melanoma. METHODS: Patients with iris melanoma who were conservatively managed on the Ocular Oncology Service, Wills Eye Hospital from 1970 to 2016 were included. Charts were retrospectively reviewed, and binary logistic regression analysis was performed. Main outcome measures were factors predictive of post-management glaucoma, defined as intraocular pressure (IOP) > 22 mmHg following melanoma treatment. RESULTS: Of 271 patients with iris melanoma, melanoma-related glaucoma was identified in 40 (15%) at presentation and post-management glaucoma developed in 75 (28%) at a mean of 103.7 months (range:1.0-120.0). Comparison (post-management glaucoma vs. no glaucoma) revealed patients with post-management glaucoma presented with worse visual acuity (20/50-20/150) (17% vs. 5%, p = 0.001), increased mean tumour basal diameter (5.1 mm vs. 4.3 mm, p = 0.004), greater melanoma-related increased IOP on presentation (24.1 mmHg vs. 16.2 mmHg, p < 0.001), diffuse tumour shape (9% vs. 4%, p = 0.01), American Joint Committee on Cancer (AJCC) T4 category (7% vs. 2%, p = 0.03), and extraocular tumour extension (7% vs. 2%, p = 0.03). Risk factors for post-management glaucoma identified by multivariate analysis included melanoma-related increased IOP at presentation (OR:1.1, [1.08-1.22] per 1-mmHg increase, p < 0.001), increased mean tumour basal diameter (OR:1.17, [1.02-1.33] per 1-millimetre increments, p = 0.03), advanced AJCC clinical T subcategory (OR:1.23, [1.04-1.46] per 1-subcategory increments, p = 0.02) and plaque radiotherapy treatment (OR:2.32, [1.13-4.75], p = 0.02). CONCLUSION: Features of iris melanoma that predicted post-management glaucoma included melanoma-related increased IOP on presentation, advanced AJCC clinical T subcategory, increased mean tumour basal diameter, and plaque radiotherapy treatment.

Conjunctival melanoma: outcomes based on tumour origin in 629 patients at a single ocular oncology centre.

PURPOSE: To investigate clinical features and outcomes of conjunctival melanoma classified by tumour origin. METHODS: Retrospective review of conjunctival melanoma patients at a single ocular oncology centre between April 18, 1974 and September 9, 2019. Lesions were divided into three tumour origin groups (primary acquired melanosis [PAM], nevus, and de novo) and clinical features and outcomes were compared. RESULTS: There were 629 patients with conjunctival melanoma that arose from PAM (n = 476, 76%), nevus (n = 59, 9%), or de novo (n = 94, 15%). A comparison (PAM vs. nevus vs. de novo) revealed patients with tumours arising from PAM presented with older mean age (62 vs. 52 vs. 55 years, p < 0.001), worse initial logMAR visual acuity (Snellen equivalent 20/30 vs. 20/25 vs. 20/25, p = 0.03), and greater clock hour involvement (4.8 vs. 4.0 vs. 3.2, p < 0.001). Tumours arising from nevus had lower frequency of fornix (31% vs. 9% vs. 24%, p = 0.02) and tarsal involvement (29% vs. 9% vs. 26%, p = 0.046) and more frequent classification as AJCC category T1 (60% vs. 89% vs. 62%, p = 0.01). After follow-up of (57.2 vs. 68.2 vs. 51.7 months, p = 0.35), tumours arising from PAM had worse mean final visual acuity (20/50 vs. 20/40 vs. 20/40, p = 0.02) and greater frequency of visual acuity loss ≥3 lines (25% vs. 15% vs. 10%, p = 0.02). Kaplan-Meier estimates for 5-year risk showed no difference by tumour origin for visual acuity loss ≥3 lines, local tumour recurrence, exenteration, metastasis, or death. CONCLUSIONS: Conjunctival melanoma most often arose from PAM, and tumour origin did not affect clinical outcomes.

Conjunctival melanoma: Risk factors for recurrent or new tumor in 540 patients at a single ocular oncology center.

PURPOSE: To investigate risk factors for recurrent or new tumor in patients with conjunctival melanoma. METHODS: Retrospective review of patients with conjunctival melanoma managed on the Ocular Oncology Service, Wills Eye Hospital from 1974 to 2019. RESULTS: There were 540 patients with mean follow-up of 57.6 months, of whom 176 (33%) had recurrent or new tumor formation. Risk factors for recurrent or new tumor on univariate analysis included presentation at older age (OR: 1.02 [1.01-1.03] per 1-year increase in age, p = 0.002), history of prior conjunctival surgery (OR: 1.62 [1.05-2.49], p = 0.03), worse visual acuity at presentation (OR: 1.76 [1.04-2.98] per 1 log-unit increase, p = 0.04), more advanced AJCC clinical T-subcategory (OR: 1.08 [1.02-1.14] per 1 subcategory increase, p = 0.01), tumor primary location in tarsal conjunctiva (OR: 1.80 [1.09-2.98], p = 0.02), and secondary tumor involvement of the fornix (OR: 1.68 [1.06-2.65], p = 0.03), and eyelid (OR: 1.92 [1.07-3.43], p = 0.03). Risk factors on multivariate analysis using all demographics, clinical features, and tumor location included presentation at older age (OR: 1.02 [1.00-1.03], p = 0.01), history of prior conjunctival surgery (OR: 1.84 [1.16-2.94], p = 0.01), and more advanced AJCC clinical T-subcategory (OR: 1.07 [1.01-1.13] per one subcategory increase, p = 0.03). CONCLUSION: On multivariate analysis, the strongest predictors of recurrent or new tumor formation following treatment of conjunctival melanoma included older age, history of prior conjunctival surgery, and advanced AJCC T-subcategory. These results suggest that earlier detection and the first surgery in conjunctival melanoma management are critical for prevention of recurrent or new tumor, and we recommend prompt referral to an experienced surgeon.

Conjunctival Melanoma: Outcomes Based on Age at Presentation in 629 Patients at a Single Ocular Oncology Center.

PURPOSE: To investigate the clinical features and outcomes for conjunctival melanoma based on patient age. METHODS: A retrospective review of patients with conjunctival melanoma managed at a single tertiary referral center from April 18, 1974, to September 9, 2019. Clinical features and outcomes were compared by patient age category at presentation (young ≤45 years, middle-aged 46-69 years, and older ≥70 years), with Kaplan-Meier and Cox proportional hazard analysis [hazard ratio (95% confidence interval)]. RESULTS: There were 629 patients categorized as young in 130 (21%), middle-aged in 278 (44%), and older in 221 (35%). A comparison by age category (young vs. middle-aged vs. older) revealed that older patients had melanoma with greater number of affected quadrants (1.7 vs. 1.8 vs. 2.0, P = 0.001) and clock hours (3.9 vs. 4.2 vs. 5.2, P = 0.001). All patients were treated with surgical excision, with no difference in requirement for additional medical or radiation therapy. By 10-year Kaplan-Meier outcomes, older patients had more frequent visual acuity loss ≥3 lines (11% vs. 28% vs. 64%, P < 0.001) and local tumor recurrence (38% vs. 46% vs. 70%, P < 0.001). Hazard ratio for the oldest age group (age ≥70) revealed a 7.76-fold (3.33-18.09) increased risk for visual acuity loss (P < 0.001), and a 2.08-fold (1.32-3.28) increased risk of local tumor recurrence (P = 0.002). There was no difference by age in risk for enucleation, exenteration, locoregional lymph node involvement, distant systemic metastasis, or death. CONCLUSIONS: Older patients with conjunctival melanoma present with more extensive disease and have increased risk for visual acuity loss and local tumor recurrence.

Conjunctival Melanoma: Outcomes based on the American Joint Committee on Cancer Clinical Classification (8th Edition) of 425 Patients at a Single Ocular Oncology Center.

PURPOSE: The aim of this study was to evaluate outcomes of conjunctiva melanoma based on the American Joint Committee on Cancer Classification (AJCC) 8th edition. DESIGN: Retrospective interventional case series. METHODS: Outcomes analysis of 425 patients. RESULTS: In this analysis of 425 patients with conjunctival melanoma, there were 266 (63%) patients classified as T1, 75 (18%) as T2, 84 (20%) as T3, and 0 (0%) as T4. A comparison (T1 vs T2 vs T3) revealed that history of primary acquired melanosis was more common in T2 (81% vs 96% vs 81%; P = 0.01) and conjunctival nevus more common in T1 (20% vs 9% vs 11%; P = 0.03). Of 381 patients with follow-up (mean of 57.6 months), comparison revealed higher T category with increasing local recurrence/new tumor (30% vs 43% vs 49%; P = 0.004), increasing exenteration (3% vs 9% vs 28%; P < 0.001), increasing melanoma-related locoregional lymph node metastasis (2% vs 7% vs 12%; P = 0.001), increasing melanoma-related systemic metastasis (9% vs 25% vs 23%; P < 0.001), and increasing melanoma-related death (4% vs 12% vs 18%; P < 0.001). A comparison at 10 years revealed visual acuity loss of >3 lines (32% vs 42% vs 63%; P < 0.001), melanoma recurrence/new tumor (47% vs 70% vs 74%; P < 0.001), exenteration (4% vs 24% vs 46%; P < 0.001), melanoma-related locoregional lymph node metastasis (3% vs 13% vs 25%; P < 0.001), melanoma-related systemic metastasis (13% vs 45% vs 40%; P < 0.001), and melanoma-related death (8% vs 22% vs 37%; P < 0.001). CONCLUSIONS: Based on the AJCC 8th edition of conjunctival melanoma, the 10-year risk per T category significantly increased for visual acuity loss of >3 lines, recurrence/new tumor, exenteration, locoregional and systemic melanoma-related metastasis, and melanoma-related death.

Risk Factors for Tumor Recurrence Following Primary Intravenous Chemotherapy (Chemoreduction) for Retinoblastoma in 869 Eyes of 551 Patients.

PURPOSE: To identify risk factors for retinoblastoma recurrence following chemoreduction. METHODS: This was a retrospective review of patients with retinoblastoma treated from 1994 to 2019 using chemoreduction with analysis for recurrence using Kaplan-Meier, Cox regression, and logistic regression. RESULTS: There were 869 eyes of 551 patients with retinoblastoma treated with chemoreduction. Follow-up in 556 eyes revealed main solid tumor recurrence (n = 355, 64%), subretinal seed recurrence (n = 244, 44%), vitreous seed recurrence (n = 162, 29%), and/or new tumor (n = 118, 21%) requiring management with focal therapy (transpupillary thermotherapy, cryotherapy) (n = 294, 53%), intra-arterial chemotherapy (n = 125, 22%), intravitreal chemotherapy (n = 36, 6%), plaque radiotherapy (n = 120, 22%), external beam radiotherapy (n = 57, 10%), and/or enucleation (n = 49, 9%). Of all recurrences, 62% were detected by 1 year, 86% by 2 years, 94% by 3 years, 98% by 5 years, 99% by 10 years, and 100% by 15 years. Risk factors for recurrence on multivariate analysis included younger patient age at presentation (odds ratio [OR] = 1.02 [1.00 to 1.04] per 1 month decrease, P = .02), greater International Classification of Retinoblastoma group (OR = 1.24 [1.05 to 1.47] per 1 more advanced group, P = .01), shorter tumor distance to optic disc (OR = 1.11 [1.01 to 1.21] per 1 mm decrease, P = .03), and presence of subretinal seeds (OR = 1.66 [1.09 to 2.53], P = .02). CONCLUSIONS: Retinoblastoma recurrence after chemoreduction is usually detected within the first 3 years following treatment. Younger patients with more advanced, posteriorly located tumors and subretinal seeds at presentation are at increased risk, but recurrence can often be managed with globe-sparing therapy.

Conjunctival Melanoma: Features and Outcomes Based on the Fitzpatrick Skin Type in 540 Patients at a Single Ocular Oncology Center.

PURPOSE: To determine the association of Fitzpatrick skin type (FST) with conjunctival melanoma. METHODS: Retrospective case series of 540 patients with conjunctival melanoma to assess clinical features and outcomes per FST. RESULTS: The FST was Type I (n = 126, 23%), II (n = 337, 62%), III (n = 56, 10%), IV (n = 8, 2%), V (n = 12, 2%), and VI (n = 1, <1%). A comparison (FST I vs. II vs. III, IV, V, and VI) revealed Types I and II associated with older mean patient age (63.9 vs. 60.7 vs. 51.1 years, p < 0.001), greater percentage of female patients (68% vs. 44% vs. 42%, p < 0.001), lower frequency of complexion associated melanosis (1% vs. 2% vs. 13%, p < 0.001), smaller tumor thickness (2.1 vs. 2.8 vs. 3.6 mm, p = 0.01), and less eyelid involvement (13% vs. 13% vs. 28%, p = 0.02). Kaplan-Meier estimates for 5-year risk showed no difference by Types for visual acuity loss ≥3 lines, local tumor recurrence, exenteration, metastasis, or death. CONCLUSION AND RELEVANCE: Most patients with conjunctival melanoma show FST I or II, and this demonstrated no association with 5-year rate of vision loss, tumor recurrence, exenteration, metastasis, or death.

Isolated Gastric Fundal Varices Caused by Diffuse Large B-Cell Lymphoma.

A 59-year-old man with diffuse large B-cell lymphoma, recently diagnosed from a renal biopsy, presented to the emergency department with melena, dizziness, and epigastric pain. He was tachycardic and had a hemoglobin level of 6.4 g/dL. Esophagogastroduodenoscopy revealed isolated gastric fundal varices with stigmata and no esophageal varices. Abdominal ultrasound with Doppler showed a normal-appearing liver, patent splenic vein and hepatic vasculature, and no splenic vein thrombosis. He was managed supportively and discharged. A positron emission tomography-computed tomography scan for staging later revealed extensive neoplastic involvement of the pancreas, gastrohepatic ligament, celiac trunk, and perigastric and splenic hilar regions.
