Treatment of advanced breast cancer with aminoglutethimide after therapy with tamoxifen

Abstract

Thirty-eight metastatic breast cancer patients were treated with Aminoglutethimide. All patients had progressive metastatic disease following initial response to Tamoxifen therapy. Thirty-two patients were evaluable for response, of these, two patients (6%) had complete remission, 13 patients (41%) had partial response, and six patients (19%) had stable disease. Eleven patients (34%) had progressive disease. The most common side effects were transient skin rash, lethargy or dizziness. Four patients' (11%) treatment was discontinued because of either skin rash or dizziness within the first two weeks of the study. These data show that Aminoglutethimide is an effective agent following Tamoxifen therapy. Cancer 50:1708-1712, 1982.
