Purpose:
To evaluate outcomes after ophthalmic plaque radiation therapy for small choroidal melanomas.
Design:
Retrospective study, case series.
Participants:
Seventy-two patients with choroidal melanomas ≥1.5 and ≤2.4 mm apical height and ≤10 mm width treated between 2002 and 2012, with a minimum follow-up of 8 months.
Methods:
All patients were treated with palladium-103 plaque brachytherapy. Mean radiation dose to the tumor apex was 82.4 Gy (range, 70.0-102 Gy).
Main Outcome Measures:
Local control, radiation complications, visual acuity, and metastatic rate.
Results:
Plaque radiotherapy provided 100% local tumor control and eye retention at a mean 54 months of observation (95% confidence interval, 46-63 months). The most common long-term brachytherapy-related complications were radiation maculopathy (43.1%) and radiation optic neuropathy (20.8%) developing at a mean of 27 months (range, 9-72 months) after irradiation. In this series, 94.4% of patients maintained 20/200 or better vision. There has been no small choroidal melanoma-related metastasis.
Conclusions:
Palladium-103 plaque radiation therapy offered excellent local control and visual acuity outcomes for patients with small choroidal melanoma.
