title: Treatment of metastatic breast cancer with aminoglutethimide after progression on chemotherapy and/or hormonal therapy with tamoxifen.
abstract: Sixty patients suffering from metastatic breast cancer, whose disease progressed on chemotherapy and/or hormonal therapy with tamoxifen, were treated with aminoglutethimide. The overall objective response rate was 33%, including 3% complete responses. The median duration of response was 8 months. Even patients who failed to respond to prior treatment modalities responded objectively to aminoglutethimide. Objective response was observed in all metastatic sites, except for lung. Subjective improvement was achieved in 70% of the patients. Although initial toxicity was high (67%), side effects of aminoglutethimide were transient, and therapy had to be discontinued in only 3 patients. The results of this study indicate that aminoglutethimide in combination with hydrocortisone is a very effective treatment for metastatic breast cancer, especially in patients with positive hormone receptors.
