Use of aminoglutethimide for the treatment of advanced breast cancer. Clinical correlations with previous treatment, oestrogen-receptor and menstrual status

In a study of 118 patients with advanced breast cancer treated with aminoglutethimide plus hydrocortisone replacement the overall objective response rate was 42 (36%). Response was not determined either by the nature or the extent of previous treatment, including endocrine therapy and/or chemotherapy, nor by oestrogen-receptor status. The vast majority of patients who responded were postmenopausal but a complete response was seen in a premenopausal patient with skin metastases. Aminoglutethimide is useful in the second-line treatment of postmenopausal subjects with advanced breast cancer.
