Estramustine phosphate therapy in poorly differentiated carcinoma of the prostate

Ninety patients with poorly differentiated prostatic carcinoma have been treated with Estramustine phosphate (Estracyt). Seventeen of them had clinically metastases and had had no previous therapy. Seventy-three were initially given oestrogens and/or irradiation. Objective response was observed in 59%. The best effect was seen in patients primarily untreated.
