title: Local recurrence of breast cancer.
abstract: Pathologic and surgical aspects of 1,027 breast cancer cases treated between 1961 and 1972 were reviewed. Sixty-eight (7%) of the cases recurred locally. This low rate of recurrence is associated with the small average diameter of 2.7 cm of all carcinomas and the correspondingly low rate of axillary lymph node metastasis of 40%. Subsequently recurring tumors had a higher incidence of axillary lymph node metastasis (68%). Eight hundred eighty-eight infiltrating duct carcinomas represented the largest group of cases and had a recurrence rate of 5.7%. Comedo, infiltrating papillary, and infiltrating lobular carcinomas recurred locally more frequently, but none of 26 mucinous carcinomas recurred. In eight cases, the recurrent tumor was of a more malignant histologic type than the primary lesion. The average width of the excised segments of skin decreased from 9.8 cm during the first three-year period (1961 to 1963) to 8.4 cm during the last period (1970 to 1972). The average width for the entire period was 9.1 cm, identical for locally recurring and nonrecurring tumors.
