[Chemotherapy for prostate cancer].

The clinical significance of chemotherapy for patients with hormone refractory prostate cancer(HRPC) is still controversial. Some randomized-controlled trials represented that mitoxantrone combined with prednisone (or hydrocortisone) provided palliative benefit to patients with HRPC. These treatments are well tolerated by elderly patients. On the other hand, the high PSA response rates have been observed in trials with both estramustine and taxane, however, higher toxicity was also recognized. The most relevant endpoint is not only palliative efficacy but also survival in these trials. Recently, the improvement of survival with docetaxel-based chemotherapy was reported. Further studies with chemotherapeutic agents will be needed to provide patients of HRPC good quality of life and longer survival.
