DTIC, CCNU, bleomycin and vincristine (BOLD) in metastatic melanoma.

Treatment of 91 consecutive patients having metastatic, Stage IV melanoma who had not received any previous chemotherapy was begun between January 1977 and April 1978. The therapy included bleomycin (B) at 7.5 units subcutaneously in the first course and 15 units in subsequent courses on days 1 and 4; vincristine or Oncovin (O) at 1 mg/m2 intravenously on days 1 and 5; CCNU or lomustine (L) at 80 mg/m2 p.o. on day 1 and DTIC (D) 200 mg/m2 intravenously on days 1 through 5. Evaluable patients (72) were those who had measurable tumours in the viscera and on the skin. Seven patients (9%) responded with complete tumor regression (CR), 22 (31%) with partial regression (PR) (50% or more tumor regression), 12 (17%) with stabilization of disease, and 31 (43%) with progression of the disease. Patients who responded with CR, PR, and stable disease (41 patients) had a median survival of 67 weeks, while those who did not respond (31 patients) had a median survival of 20 weeks (P < .0001). Overall median survival was 31 weeks. The bleomycin-Oncovin-lomustine-DTIC (BOLD) regimen is an effective alternative treatment for metastatic melanoma; there is good tumor response and prolongation of survival in the responding patients. Its overall toxicity is mild to moderate.
