Abstract:
We analyzed the results of local re-excision after radiation therapy on seven patients with positive surgical margins at the initial breast-conserving surgery. The age of the patients ranged from 30 to 55 years, and the tumor sizes from 1.1 to 4.7 cm. Both estrogen receptor and progesterone receptor status were positive in two patients, negative in four, and unknown in one. Pathological examination revealed residual carcinoma in one (14.3%) of seven patients. The immunohistochemical results of the initial specimen were estrogen receptor-positive, c-erbB-2-positive, and Bax-negative. We performed local re-excision after radiation therapy and found only one incidence of residual carcinoma in the conserved breast.
