Objective: To evaluate the efficacy and complications of stereotactic radiotherapy in the management of patients with juxtapapillary choroidal melanoma.
Design: Retrospective review.
Participants: 64 patients with juxtapapillary choroidal melanoma.
Methods: Consecutive patients with juxtapapillary choroidal melanomas located within 2 mm of the optic nerve, treated with stereotactic radiotherapy at Princess Margaret Hospital from October 1998 to January 2006, were reviewed for treatment effect and complication rates.
Results: Median age was 63 years. Median tumor height was 4.2 mm, and median maximum tumor diameter was 9.8 mm. The prescribed radiation dose was 70 Gy in 5 fractions over 10 days, and the median follow-up was 26 months. After treatment, there was local tumor recurrence in 3 patients, and in 8 patients there was systemic progression. Actuarial rates of local tumor control, metastases, and survival at 26 months were 94%, 12%, and 94%, respectively. Rates of radiation-induced neovascular glaucoma, cataract, retinopathy, and optic neuropathy at 26 months were 28%, 45%, 80%, and 52%, respectively. Enucleation was necessary for 7 patients.
Conclusions: Stereotactic radiotherapy offers a noninvasive alternative with acceptable ocular toxicity rates to enucleation and brachytherapy in the management of juxtapapillary choroidal melanoma.
