Abstract

Both iodine-125 ((125)I) Collaborative Ocular Melanoma Study and ruthenium-106 ((106)Ru) eye plaques can achieve excellent tumor control in patients diagnosed with uveal melanoma. We analyzed our single institutional experience in the management of ocular melanoma treated with either (125)I or (106)Ru plaque brachytherapy.The records of 107 patients with uveal melanoma treated with either (106)Ru (n = 40) or (125)I (n = 67) plaque brachytherapy between 2000 and 2008 were retrospectively reviewed. Tumor control parameters and toxicity were assessed.Actuarial 5-year rates of local control, progression-free survival, and overall survival with (106)Ru were 97%, 94%, and 92%, respectively. For (125)I, these values were 83%, 65%, and 80%. In the subset of patients with tumor apex height =5 mm (36 (125)I and 40 (106)Ru), there was no difference in overall survival; however, progression-free survival was significantly improved with (106)Ru (P = .02). Enucleation-free survival was significantly different between the 2 subsets, with no enucleations in the (106)Ru cohort (P = .02). Patients treated with (106)Ru experienced reduced retinopathy (P = .03) and cataracts (P < .01).Both (125)I and (106)Ru eye plaque brachytherapy treatment result in encouraging tumor control for patients with uveal melanoma. We demonstrate that (106)Ru offers these benefits with reduced toxicity in patients treated for uveal melanomas =5 mm in apical height.
