Abstract | BACKGROUND: METHODS: Nine patients with progressive metastatic HRPC completed at least one cycle of combination therapy employing weekly paclitaxel plus estramustine. Paclitaxel was given weekly for 3 weeks as a 2-h intravenous infusion at a dose of 100 mg/infusion. The cycle was repeated every 4 weeks. A dose of 280 mg of oral estramustine was administrated twice daily for 21 days from the first day of each cycle. Both efficacy and toxicity were recorded. RESULTS: Grade 1 sensory neuropathy was seen in three patients (33%) and grade 4 thrombopenia/ anemia was seen in one patient (11%). Performance status improved in three of seven patients (43%), while six patients (67%) showed a 50% or greater decline in prostate-specific antigen levels. Two of these patients experienced significant improvement in bone pain. One patient died of cardiac infarction during this trial and another died of disseminated intravascular coagulopathy subsequent to gastrointestinal bleeding. An additional patient suffered non-fatal pulmonary infarction. The one-year median survival rate was 22.2% and the overall survival period was 36 weeks. CONCLUSION: Although weekly paclitaxel plus estramustine may pose a significant risk, this combination may have a beneficial effect on the quality of life HRPC patients. A well-designed phase I-II trial in an Asian male population is highly recommended.
