Uveal melanoma is the most common primary intraocular malignancy in adults and the liver is the most common site for systemic metastases. We conducted a phase II clinical trial for patients with hepatic metastases from uveal melanoma using chemoembolization of the hepatic artery with 1,3-bis(2-chloroethyl)-1-nitrosourea (BCNU) dissolved in ethiodized oil. Gelatin sponge particles were used as a transiently occlusive agent. The responses in hepatic metastases, overall survival, time to progression and side-effects related to chemoembolization were evaluated. Thirty patients were enrolled. Twenty-four patients completed at least one treatment to all targeted liver metastases and were evaluable for hepatic response. Eighteen of these 24 patients experienced regression or stabilization of hepatic metastases for at least 6 weeks (one complete response in hepatic metastases; four partial responses; 13 stable disease). One of the 13 patients with stable disease was rendered free of disease by surgical removal of metastases after chemoembolization (surgical complete response). The overall response rates (complete and partial responses) for intention-to-treat patients and for patients who were evaluable for response were 16.7 and 20.4%, respectively. The median overall survival of the entire intention-to-treat group of patients was 5.2 months (range, 0.1-27.6 months), for patients with complete or partial response in hepatic metastases 21.9 months (range, 7.4-27.6 months), for patients with stable disease 8.7 months (range, 2.9-14.4 months) and for patients with progressive disease 3.3 months (range, 1.6-5.6 months). Importantly, 13 of the 18 patients who achieved complete response, partial response or stable disease subsequently developed progression of extrahepatic metastases with control of hepatic metastases. Chemoembolization with BCNU is a useful palliative treatment for the control of hepatic metastases in uveal melanoma patients. However, progression in extrahepatic sites after stabilization of hepatic metastases requires further improvement in the therapeutic approach to this disease.

Brain metastases continue to be a major and growing challenge in oncology, but recent advances in surgery, radiosurgery, and chemotherapy have broadened the number of treatment options. Current approaches to the management of brain metastases focus on individualizing patient care based on factors including the Karnofsky Performance Status, the tumor histology, the number of metastases, and the status of the systemic disease. A number of treatment approaches have been shown to be effective for brain metastases, including surgery; radiosurgery; whole-brain radiotherapy; and, more recently, chemotherapy. The use of adjuvant whole-brain radiotherapy with local therapies, such as surgery or radiosurgery, along with newer chemotherapy options, such as targeted biological agents, temozolomide, and implantable 1,3-bis(2-chloroethyl)-1-nitrosourea (BCNU) Gliadel wafers, are at the forefront of recent advances in the treatment of patients with brain metastases that may provide longer survival and improved quality of life. Although there is no current standard treatment, some general guidelines are recommended for single metastases, oligometastases (two to three brain metastases), and multiple (four or more) brain metastases, and for new or recurrent disease. With advances in systemic therapy for cancer, the treatment of brain metastases is becoming an increasingly important determinant of the length of survival and quality of life for cancer patients.
