Treatment of advanced breast cancer with aminoglutethimide--response after previous tamoxifen treatment

Abstract

Thirty-one postmenopausal patients with advanced breast cancer either unresponsive to tamoxifen or progressing after responding to tamoxifen were treated with aminoglutethimide (1 000 - 1 250 mg/d) plus hydrocortisone replacement. The response rate was 33% in patients who had never responded to tamoxifen and 47% in patients who had previously responded to tamoxifen. The overall response rate was 42%. These results show that aminoglutethimide is an effective second-line hormonal treatment for patients with advanced breast cancer.
