| Popis: | Background: Docetaxel based chemotherapy not only reduces pain and improves quality of life in advanced hormone refractory prostate cancer (HRPC), but it also improves survival. We investigated the combination of docetaxel and estramustine in patients with HRPC regarding efficacy and prognostic parameters. Patients and Methods: We conducted a phase-II trial, administering docetaxel (70 mg/m2 i.v., day 2, every 3 weeks) and estramustine (280 mg 3 times daily p.o., 1 day prior to docetaxel, on 5 consecutive days) to patients with HRPC. Patients were monitored for PSA (prostate-specific antigen) response and toxicity. Results: 62 patients were treated. The median age was 67.5 years, the median PSA was 177.9 ng/ml. The median number of cycles was 6. The median time to progression (TTP) and median survival time were 14 (±2) and 24 (±5) months, respectively. A = 50% decrease in PSA levels from baseline occurred in 38 (61.3%) patients of whom 25 (40.3%) had a = 75% PSA decrease. The main grade 3-4 hematologic toxicities were neutropenia 34% and anemia 18%. Conclusions: The combination of docetaxel and estramustine exerts substantial activity in HRPC suggesting an overall survival benefit with manageable toxicity. This trial also demonstrated a survival advantage for patients with early chemotherapeutic intervention. We identified PSA relapse, baseline PSA and hemoglobin as valuable prognostic factors in this setting. |
