title: Survival of patients and metastatic and local recurrent tumor growth in malignant melanoma of the uvea after ruthenium plaque radiotherapy.
abstract: A series of 100 consecutive patients treated by ruthenium plaque radiotherapy for uveal malignant melanoma from 1981 to 1991 was studied to evaluate local recurrences, metastases, and melanoma-specific mortality. Follow up ranged from 1.0 to 10.1 years (mean, 3.3; median, 3.0 years). Local relapse was observed in 19 patients from 0.1 to 2.7 years (median, 0.7 years) after therapy. Six of these eyes were enucleated. The 5-year probability of local tumor control was 59%. Seven patients with local relapse developed metastasis 0 to 4.3 years (median, 1.4 years) later. Altogether, 18 patients developed metastases 0.9 to 4.6 years (median, 2.0 years) after the irradiation, and 15 of them died of melanoma 5 days to 3.3 years (median, 0.5 years) after detection of metastases. The 5-year probability of metastasis not developing was 61%. The overall 5-year survival was 78%, excluding causes other than malignant melanoma. Large tumor size and anterior tumor location, with or without ciliary body involvement, predicted poor prognosis both in terms of local growth, metastases, and melanoma-specific mortality. Local recurrent tumor growth was associated with a significant increase in metastasis but a nonsignificant increase in melanoma-specific mortality.
