OUTLINE: This is a randomized multicenter study. Patients are stratified according to risk group: low volume disease (no more than 2 lesions on bone scan), intermediate volume (more than 2 bone lesions confined to axial skeleton), or high volume (bone lesions in appendicular skeletal or visceral lesions). Patients are randomized to one of two treatment arms. Arm I: Patients receive oral estramustine three times a day and oral etoposide twice daily on days 1-14 and paclitaxel IV over 1 hour on day 2. Treatment repeats every 21 days. Arm II: Patients receive doxorubicin IV on days 1, 15, and 29, vinblastine IV on days 8, 22, and 36, oral ketoconazole three times a day on days 1-7, 15-21, and 29-35, and oral estramustine three times a day on days 8-14, 22-28, and 36-42. This regimen consists of 6 weeks of alternating chemotherapy and 2 weeks rest, for an 8 week course. Treatment continues in the absence of disease progression or unacceptable toxicity.
