Uveal melanoma is the most common primary intraocular malignant tumor in adults and the second most common type of primary malignant melanoma in the body. It represents 5% to 6% of all melanoma diagnoses. Metastasis is by vascular spread, and approximately 40% to 50% of patients with primary uveal melanoma will ultimately develop metastases. At the time of diagnosis, over 99% of patients have disease limited to the eye, but at least 30% of these patients will die of systemic metastases at 5 years and 45% at 15 years. 1 Of the patients who die of uveal melanoma, 62% and 90% do so within 5 and 15 years, respectively. The liver is involved in up to 95% of individuals who develop metastatic disease. 2,3 The survival of patients with metastatic uveal melanoma is directly related to the presence of liver metastasis. Liver is the first site of systemic metastasis for most patients and the exclusive site of systemic metastasis in approximately 40% of the patients. The clinical course of patients with uveal melanoma is determined by progression of the disease in the liver. Despite therapy, the median survival of patients who develop liver metastases is reported to be about 6 months, and the 1-year survival is estimated to be 10% to 15%. 4 In contrast, patients with metastatic melanoma confined to extrahepatic sites have a median survival of approximately 19 to 28 months with 76% of the patients surviving over a year. 1,5,6 n Prognosis and Treatment of Disseminated
Uveal MelanomaDespite advances in diagnosis and management of the primary uveal melanoma, systemic uveal melanoma metastases are difficult to treat. 6 The management of metastatic uveal melanoma is dependent on whether metastatic disease is confined to the liver. Regional therapies such as surgical resection, isolated hepatic perfusion, intraarterial hepatic
