[A randomized trial of endocrine therapy, chemotherapy, and chemo-endocrine therapy in advanced breast cancer].

A randomized trial of endocrine therapy (adreno-oophorectomy, H), chemotherapy (FAC, C), chemoendocrine therapy (FAC + tamoxifen, H'C, or FAC + adreno-oophorectomy, HC) was performed in 114 advanced breast cancer patients from September, 1979 to December, 1983, and 106 were evaluable. The response to H, C, H'C, and HC was shown to be 33% (10/30), 54% (14/26), 59% (17/29), and 76% (16/21), respectively. There was a significantly higher response rate in HC group than H group. Higher but not significantly different response was obtained by H'C as compared with H. There were no significant differences in the overall survival among the treatment arms. However, patients treated with H survived longer (greater than 5 years). These results suggest that higher response obtained by chemotherapy, alone or in combination with endocrine therapy does not seem to contribute to the prolongation of survival of the patients.
