Randomized sequential hormonal therapy vs adrenalectomy for metastatic breast carcinoma.

One hundred sixty-one postmenopausal and 65 premenopausal women, a total of 226 patients with metastatic breast carcinoma, were included in this randomized study to evaluate the merits of adrenalectomy as the primary mode of therapy as compared to the customary sequential hormonal manipulation. The 145 evaluable postmenopausal patients were randomized as follows: (1) primary additive hormone therapy first followed by adrenalectomy and (2) primary adrenalectomy followed by chemotherapy and/or additive hormone therapy. When 76 patients in group 1 were compared with 70 patients in group 2 regarding their survival time, there was no essential difference, but the response rate was 20% vs 38.6%, a significant difference. The 55 evaluable premenopausal women were randomized into two groups: (1) oophorectomy followed by adrenalectomy; (2) adrenalectomy-oophorectomy as primary mode of therapy. The response rate in group 1 was 17.4% as compared with 41.9% in group 2, but again there was no difference in the survival time among these two groups. When sequential hormonal manipulation was utilized, only one-third of these patients were subjected to adrenalectomy because of their rapidly deteriorating condition. Adrenalectomy performed as a secondary procedure showed a lower response rate but the total survival time was comparable with primary adrenalectomy patients.
