Abstract

Purpose: To investigate clinical manifestations and prognoses in pediatric patients (≤12 years old) with ocular melanoma. Methods: This was a retrospective, multicenter cohort study with individual participant data (IPD) meta-analysis pooling available published cases, and unpublished cases from an international collaboration of seven ocular oncology centers. Results: There were 133 eyes of 133 pediatric patients with choroidal or ciliary body (n = 66 [50%]), iris (n = 33 [25%]), conjunctival (n = 26 [19%]), and eyelid (n = 8 [6%]) melanoma. Overall, the mean patient age at presentation was 7 years (median, 8; range, 1-12 years), with 63 males (49%). The mean age by tumor site was 6.50 ± 3.90, 7.44 ± 3.57, 9.12 ± 2.61, and 5.63 ± 2.38 years, for choroid/ciliary body, iris, conjunctiva, and eyelid melanoma, respectively (P = 0.001). Association with ocular melanocytosis was seen in 15%, 11%, 4%, and 0%, respectively (P = 0.01). Frequency of ocular melanoma family history did not vary by tumor site (7%, 17%, 9% and 12%, resp. [P = 0.26]). After mean follow-up of 74, 85, 50, and 105 months (P = 0.65), metastasis was seen in 12%, 9%, 19%, and 13% of choroid/ciliary body, iris, conjunctiva, and eyelid melanoma, respectively. Death was reported in 5%, 3%, 8%, and 0%, respectively, with survival analysis indicating higher mortality in choroidal/ciliary body and conjunctival melanoma patients. Conclusions: Ocular melanoma in the pediatric population is rare, with unique clinical features and outcomes. Iris melanoma accounts for about one-third of pediatric uveal melanoma cases.[Formula presented] © 2023 American Association for Pediatric Ophthalmology and Strabismus
