The Southwest Oncology Group has completed a study of 213 women with the first recurrence of breast cancer. Eligibility included a radical or modified radical mastectomy for cure and recurrence which had received no other form of therapy. Patients were started on tamoxifen (TAM) 20 mg daily (Phase I). Failures, or responders who subsequently failed, had an oophorectomy if the ovaries were intact, and TAM was continued (Phase II). During Phase III, eligible patients underwent an adrenalectomy, and lastly, in Phase IV, patients received chemotherapy. Responses to TAM were seen in 40% of 56 premenopausal patients, 46% of 95 postmenopausal women, and 44% of 62 patients without intact ovaries. Oophorectomy plus TAM gave responses only in premenopausal women who failed to respond on TAM or in postmenopausal patients who had a prior response to TAM. Adrenalectomy was successful in 7 of 21 patients. Chemotherapy resulted in 13% complete and 47% partial responses. Median overall survival was 108, 155, and 115 weeks, respectively, for the three patient groups. The authors believe that until results with chemotherapy improve significantly, hormonal therapy is the preferred first‐line management of recurrent breast cancer.
