title: Combined endocrine treatment of postmenopausal patients with advanced breast cancer. A randomized trial of tamoxifen vs. tamoxifen plus aminoglutethimide and hydrocortisone.
abstract: The therapeutic efficacy of combined endocrine therapy with tamoxifen, aminoglutethimide and hydrocortisone (T+AG+H) was evaluated against treatment with tamoxifen (T) alone in 210 patients above 65 years of age with metastatic breast cancer. The treatment results have been assessed for the 166 fully evaluable patients and were the following for the T and T+AG+H groups, respectively: PD: 31 and 35%; NC: 35 and 37%; PR: 13 and 16%; and CR: 21 and 12%. The overall treatment results are not statistically different (p = 0.35) and the 95% C.L. of the difference of the response rates are -8% to +20%. The median duration of remission was approximately 24 months in both treatment groups (p = 0.31). The time to treatment failure was comparable with median values of 10 and 8 months in the T and the T+AG+H groups respectively (p = 0.17). Toxicity was more frequent and severe in the combined treatment group and could in most instances be attributed to treatment with AG+H. In conclusion, the simultaneous use of T and AG and H does not seem to improve the therapeutic results in postmenopausal patients with advanced breast cancer.
