We report the results from 106 patients with extracapsular (stage C) or widespread (stage D)prostatic cancer, who were treated with cyproterone acetate and orchiectomy and followed for 5 years. As controls we used 40 patients, chosen at random, with stage C and stage D cancer of the prostate gland who were treated with stilbestrol and orchiectomy. The survival rate is improved in patients treated with cyproterone acetate and orchiectomy compared to the patients treated with stilbestrol and orchiectomy. Treatment with cyproterone seems more effective in those patients with low-stage and low-grade prostatic cancer. The side effects of this therapy are less and milder than those described in estrogenic treatment alone or with orchiectomy.
