Calusterone was given at a dose of 200 mg daily to 45 postmenopausal patients with advanced metastatic breast cancer. Of the 40 evaluable patients, 11 were unable to tolerate the drug because of severe toxicity. Objective regression of soft tissue disease and relief of bone pain were seen in four patients (9.1%) for an average duration of 15.2 weeks. Thirteen patients showed an arrest of disease progression. In 12 patients the lesions continued to progress in spite of therapy. Toxic effects consisting of nausea, vomiting, fluid retention, SGOT elevation, and androgenic side effects were seen in 33 patients (75%), necessitating discontinuation of the drug in 11 (25%).

Androgens are effective therapeutic agents in postmenopausal women with metastatic breast cancer. Early studies with testosterone propionate showed objective regression rates of slightly more than 20%. Subsequent work with synthetic androgens has failed to show a significant reduction in toxicity or an increase in therapeutic efficacy over testosterone propionate. Calusterone (7 beta,17 alpha-dimethyltestosterone), in early clinical trials, showed both of these qualities and was believed by some to be the "ideal androgen." As with many new drugs, subsequent work failed to confirm these early findings, and most of the later data gathered on calusterone are inconsistent. We conclude from our knowledge at present that calusterone offers no real advantages or disadvantages over other androgens in the treatment of breast cancer.

Calusterone (7 alpha, 17beta-dimethyltestosterone) is an orally effective weakly androgenic steroid. The antitumor efficacy of calusterone, 200 mg per day against objectively progressing advanced breast cancer in females has already been reported. In the present study calusterone was used in metastatic breast cancer in two male patients. Both had failed to continue respond to orchiectomy and had measurable lesions one in the lungs, the other in the bones. Both patients showed objective regression (blastic response of osteolytic lesions and disappearance of lung metastases) lasting five months in one patients and more than seven months in the other, who is still in regression. Further experience is necessary for statistically adequate results.
