Abstract

Purpose: To compare the effectiveness of pars plana vitrectomy endoresection with iodine-125 brachytherapy in the treatment of choroidal melanoma.

Design: A nested case-control study (1:2) from a surgical cohort.

Methods: The study comprised 81 choroidal melanoma patients treated with either endoresection or iodine-125 brachytherapy. Twenty-seven patients who had undergone endoresection were matched according to tumor height and postequatorial tumor location with 54 cases treated with iodine-125 brachytherapy. Metastatic disease, overall survival, local tumor recurrence, visual acuity, and secondary enucleation rates were analyzed and compared between groups.

Results: Metastatic spread was observed in 11 patients in the iodine-125 brachytherapy group vs only 1 patient in the endoresection group (20.4% and 3.7%, respectively, P = .053). Fourteen patients died during follow-up: 11 in the brachytherapy arm vs 3 in the endoresection arm (20.4% and 11.1%, respectively, P = .238). For the iodine-125 brachytherapy and endoresection groups, respectively, the 5-year Kaplan-Meier estimates were as follows: overall survival, 81.5% vs 89.2% (log-rank test, P = .429;); relapse-free survival, 96.6% vs 92.4% (P = .2); visual acuity retention equal or superior to 20/200, 66.4% vs 59.9% (P = .083), and eye retention, 85.7% vs 87.8% (P = .942).

Conclusions: Endoresection for choroidal melanoma is an effective treatment modality in selected cases of posterior choroidal melanomas, with outcomes similar to those obtained with iodine-125 brachytherapy.
