Combined external and interstitial irradiation in the treatment of stage III breast cancer.
One hundred six patients with locally advanced carcinoma of the breast underwent definitive radiation therapy for loco-regional control following incisional and/or needle biopsy. Doses of external and interstitial irradiation were 5000 rad (50 Gy) in 5 to 6 weeks, and 3000 to 4000 rad (30-40 Gy) in 60 to 80 hours, respectively. Forty-eight of 106 patients (45%) also received adjuvant systemic chemotherapy. Loco-regional control was observed in 93 of the 106 patients (88%), with five-year disease-free survival of 47%. Distant metastases developed in 59 of the 106 patients (56%). Good to satisfactory cosmetic results were obtained in the majority of these patients; morbidity was at an acceptable level. Locally advanced breast cancer can be treated adequately and satisfactorily without mastectomy by a combination of external and interstitial irradiation.
