Prostate cancer is the most frequently diagnosed cancer and the second leading cause of cancer death in men in the United States. In 1997 it was estimated that more than 41,000 men died of this disease. Treatment of metastatic disease remains palliative, with androgen ablation used as first- line therapy. After failure of androgen ablation, chemotherapy can now be used to induce a remission in many men. Treatment regimens that include paclitaxel (Taxol; Bristol-Myers Squibb Company, Princeton, NJ) have been particularly successful in treating hormone-refractory prostate cancer in the phase II setting. We have conducted a trial of estramustine 280 mg orally three times per day for 14 days combined with etoposide 50 mg/m2/d (in general, one 50-mg tablet twice a day) for 14 days, with paclitaxel 135 mg/m2 over 1 hour on day 2. This regimen is repeated every 21 days for a maximum of six cycles. Patients responding to therapy are then given a break and re-treated at physician discretion. On preliminary analysis, 24 of 38 patients demonstrated a decline in pretreatment prostate-specific antigen of more than 50% (63%). The regimen was well-tolerated and only seven patients demonstrated grade 3 or 4 neutropenia. Further analysis is ongoing.
