[Antitumoral activity of calusterone in advanced mammary carcinoma (author's transl)].

Thirty-one post-menopausal patients with advanced mammary carcinoma were treated with calusterone (7-beta, 17-alpha-dimethyl-testosterone), 200 mg daily per os for at least three months. Twenty-seven patients were avaluable. Eight patients (29%) had an objective response; two patients had a complete remission maintained for more than eighteen months by repeated three-month courses of therapy. In eight patients (29%), calusterone produced no objective response, without disease progression. The main side effects have been hirsutism, acne and gastro-intestinal distress; no libido modification was observed. Increased BSP retention was observed in one third of patients.
