[Clinical course of hormone refractory cancer of the prostate].

Analysis of the clinical progression of 61 patients with prostate cancer undergoing hormone therapy. PSA allowed early detection in 86.9% cases. In 25 patients no rescue treatment was instituted, and 36 patients were treated with estramustine phosphate resulting in decreased PSA levels in 58% and objective response in 36%. Of these, 82% showed decreased PSA levels for over six months. Survival rate was higher in respondent, treated patients and comparable in non-respondents, treated versus non treated patients.
