PURPOSE:The purpose of this study is to evaluate patients with uveal metastasis based on primary tumor site.METHODS:Retrospective analysis from Wills Eye Hospital, Philadelphia, PA, USA, for uveal metastasis clinical features and outcomes based on the primary tumor site.RESULTS:There were 2214 uveal metastases diagnosed in 1111 consecutive patients. The demographics included mean age of 60 years (median 61 years), Caucasian race (88%), and female gender (64%). The tumor was unilateral (82%) and primary site was established before uveal metastasis (67%). The primary tumor originated in the breast (37%), lung (26%), kidney (4%), gastrointestinal (GI) tract (4%), cutaneous melanoma (2%), lung carcinoid (2%), prostate (2%), thyroid (1%), pancreas (1%), other sites (3%), and unknown (16%). Comparative analysis of the 5 most common primary sites (breast, lung, kidney, GI tract, and cutaneous melanoma), revealed metastasis at mean age (57, 62, 66, 61, 59 years), as unilateral tumor (74%, 86%, 85%, 93%, 85%), with mean number of metastasis/eye (1.9, 1.7, 1.0, 1.1, 2.0), and in females (99%, 46%, 26%, 25%, 30%). Choroidal metastases measured mean base (9.3, 10.2, 9.1, 11.0, 7.3 mm), mean thickness (2.4, 3.6, 4.4, 4.0, 2.9 mm), and demonstrated predominant color yellow (94%, 91%, 56%, 97%, 36%). Of the 769 patients with documented follow-up, mean patient survival was poor (22.2, 11.5, 8.6, 12.4, 11.4 months) and Kaplan–Meier analysis revealed 3-year survival (33%, 19%, 0%, 14%, 21%) and 5-year survival (24%, 13%, 0%, 14%, 21%). The worst survival was found in patients with pancreatic metastasis (mean 4.2 months) and best survival with lung carcinoid (92% at 5 years).CONCLUSION:In a tertiary referral service, uveal metastasis originates from cancer in the breast, lung, kidney, GI tract, cutaneous melanoma, or others. Overall prognosis is poor with 5-year survival at 23% and worst survival with pancreatic metastasis whereas best survival with lung carcinoid metastasis.

Purpose: To use multimodal imaging for identification of risk factors for choroidal nevus transformation into melanoma. Methods: Retrospective chart review of 3806 consecutive choroidal nevi with imaging and 2355 choroidal nevi with additional follow up to identify factors predictive of transformation of choroidal nevus into melanoma. Results: The median patient age was 62.5 years and Caucasian race in 3167 (95%). The choroidal nevus demonstrated median basal diameter of 4.0 mm and thickness of 1.4 mm. Imaging included optical coherence tomography (OCT) showing subretinal fluid (SRF) in 312 (9%), ultrasonography (US) with acoustic hollowness in 309 (9%), and hyper-autofluorescence (AF) in 100 (3%). Of those 2355 choroidal nevi with follow up, Kaplan-Meier estimates of nevus transformation into melanoma at 1, 5, and 10 years were 1.2%, 5.8%, and 13.9%, respectively. Multivariate analysis, using multimodal imaging for detection of factors predictive of nevus transformation into melanoma, included thickness >2 mm on US (hazard ratio (HR) 3.80, p < 0.0001), SRF on OCT as cap over nevus (HR 3.00, p < 0.0001) or SRF ≤3 mm from nevus margin (HR 3.56, p = 0.0003), symptomatic vision loss ≤20/50 on Snellen visual acuity (VA) (HR 2.28, p = 0.005), orange pigment (lipofuscin) hyperautofluorescence on AF (HR 3.07, p = 0.0004), acoustic hollowness on US (HR 2.10, p = 0.0020), and tumor diameter >5 mm on photography (HR 1.84, p = 0.0275). These factors can be recalled by the mnemonic “To Find Small Ocular Melanoma Doing IMaging” (TFSOM-DIM) representing Thickness >2 mm (US), Fluid subretinal (OCT), Symptoms vision loss (VA), Orange pigment (AF), Melanoma hollow (US), and DIaMeter >5mm (photography). The mean 5-year estimates of nevus growth into melanoma were 1% (HR 0.8) for those with 0 risk factor, 11% (HR 3.09) with 1 factor, 22% (HR 10.6) with 2 factors, 34% (HR 15.1) with 3 factors, 51% (HR 15.2) with 4 factors, 55% (HR 26.4) with 5 risk factors, and not-estimable with all 6 risk factors. Conclusion: In this analysis, multimodal imaging was capable of detecting risk factors for nevus transformation into melanoma, including thickness >2 mm (US), fluid subretinal (OCT), symptoms vision loss (Snellen acuity), orange pigment (AF), melanoma hollowness (US), and diameter >5 mm (photography). Increasing number of risk factors imparts greater risk for nevus transformation into melanoma, including thickness >2 mm (US), fluid subretinal (OCT), symptoms vision loss (Snellen acuity), orange pigment (AF), melanoma hollowness (US), and diameter >5 mm (photography). Increasing number of risk factors imparts greater risk for transformation.
