Estramustine versus conventional estrogenic hormones in the initial treatment of highly or moderately differentiated prostatic carcinoma. A randomized study.

Abstract

In a prospective randomized multicenter trial patients with highly or moderately differentiated prostatic carcinoma, previously untreated, were allotted either to oral Estramustine phosphate or to intramuscular polyestradiol phosphate plus oral ethinyl estradiol. As regards frequency and duration of tumour remission there was no statistical difference between the two groups. Nor did they differ significantly with respect to adverse reactions. This is an interim report and will be followed later on by a final evaluation.
