A randomised trial of tamoxifen versus tamoxifen with aminoglutethimide in post-menopausal women with advanced breast cancer.

Sixty-six post-menopausal women with metastatic breast cancer were randomised to receive tamoxifen or tamoxifen with aminoglutethimide. The women in the tamoxifen group were virtually free of toxicity, whilst 45% of patients in the aminoglutethimide group had toxicity and 13% discontinued the drug because of this. Responses were seen in 19% of patients receiving tamoxifen alone and 23% of those receiving both drugs. There is no indication that the increased toxicity seen with the addition of aminoglutethimide to tamoxifen in this situation is justified by an increased response rate.
