Locally recurrent breast carcinoma: the effect of adjuvant chemotherapy on prognosis.

A group of 72 patients who had received radiotherapy between 1972 and 1980 for isolated local-regional recurrence of breast cancer was studied; 38 had received adjuvant chemotherapy and 34 had not. The two groups were comparable except for the initial nodal status and median time from mastectomy to recurrence. Outcome was not significantly different for the two groups in terms of response to radiotherapy, incidence of re-recurrence, distant metastases, and three-year survival. The length of the disease-free interval and the response to radiotherapy were the only factors studied that were significantly related to survival.
