The purpose of this study was to assess the efficacy of weekly administration of docetaxel as a single agent in patients with hormone-refractory, symptomatic, metastatic prostate cancer with respect to symptom palliation, tumor response, time to progression, and survival. Sixty men with progressive metastatic prostate cancer that had progressed on at least one hormonal regimen were enrolled in this multicenter phase II study. Twenty-one percent of patients had received prior palliative radiotherapy, and 25% had received prior chemotherapy for hormone-refractory disease. Patients were scheduled to receive three 8-week cycles of docetaxel (36 mg/m(2) on days 1, 8, 15, 22, 29, and 36) with 2-week intervals between cycles. The docetaxel dose could be decreased in the event of toxicity, but no dose escalation was permitted. A > or =50% decrease in serum prostate-specific antigen (PSA) levels from baseline with stabilization or improvement of performance status lasting 2 months or longer occurred in 24 (41%) patients, of whom 16 (27%) had a > or =80% decrease for 2 months or more. The median time to progression for all patients was 5.1 months (range, 0.9 to 18.2 months). The estimated median time to progression for patients who had and those who did not have a > or =50% reduction in serum PSA level with stable or improved performance status was 6.65 and 4.3 months, respectively. The median overall survival was 9.4 months (range, 1.6 to 18.2 months). Treatment toxicity was considered acceptable. Single-agent docetaxel at 36 mg/m(2) weekly was associated with a PSA response rate of 41%, increased time to progression and survival, and minimal myelosuppression in patients with hormone-refractory metastatic prostate cancer.
