OBJECTIVE To report the results of a randomized phase II trial of docetaxel with and without estramustine phosphate (EP) in patients with hormone-refractory prostate cancer (HRPC). PATIENTS AND METHODS Patients with progressive HRPC were randomized to receive docetaxel 70 mg/m(2) on day 1 (arm A), or docetaxel 70 mg/m(2) on day 2 plus oral EP three times daily, at a total daily dose of 840 mg, on days 1-5 (arm B). The primary objective of the trial was to evaluate the activity of the treatments in terms of the response in prostate-specific antigen (PSA) level. RESULTS Forty-five of the 49 patients centrally randomized to arm A and 44 of the 46 in arm B were evaluable for activity. The PSA level decreased by >= 50% in 40% of the patients in arm A and in 75% of those in arm B. The median time to PSA progression was 20 weeks in arm A and 30 weeks in arm B. The patients in arm B had an improvement in pain over time. CONCLUSION These data support the existence of a possible advantage in combining docetaxel and EP, which should be verified in a specific randomized phase III study.
