Abstract
Short-term treatment failures following 43 segmental mastectomies without radiation therapy and 157 total mastectomies for primary operable breast cancer Stages I and II (T1–2, N0–1, MO) are compared. Although not randomized by design, the patients in the two treatment groups were of similar age and had tumors of comparable histologic type, size, grade, and stage. The overall recurrence rates in an average follow-up of 24 months (range, 6–48 months) were 5% for patients treated by standard mastectomy and 19% for those treated by segmental mastectomy. Recurrence rates in patients with the more commonly encountered carcinomas of 11 to 50 mm in size treated by surgery alone were 7.5% for total mastectomy and 28.0% for segmental mastectomy. Nearly all of this difference relates to a higher frequency of local recurrence in the segmental mastectomy group (P = Cancer 52:2173-2179, 1983.
