Abstract

From 1948 to 1975, at the Istituto Nazionale Tumori of Milan, 209 patients underwent extended radical mastectomy (ERM) for breast cancer classified as T1 N0-1, M0. In 57 patients (27.3%), the ERM was preceded by an excisional biopsy performed in the outpatient clinic (Group A), of which 75% were performed within 30 days of admission and 25% after 30 days (average, 25 days; range 5-99). The remaining 152 patients (Group B) underwent an extemporaneous frozen biopsy. There was no difference in the distribution of the histologic types in the two groups. The axillary lymph nodes (N) and the internal mammary chain (MI) were free of neoplastic invasion (N-, MI-) in 156 patients (74.6%), 44 in Group A (77.2%) and 112 in Group B (73.7%). Actuarial 10-year survival of the patients was 79.9% in Group A and 77.7% in Group B (p = NS). It was 90% in N- MI- patients of Group A and 81.9% in those of Group B (p = NS). Instead, for N+ patients, actuarial survival at 10 years was 50% in Group A and 67% in Group B (p = NS), and for MI+ patients it was 50% and 49.8%, respectively. These present data do not support the hypothesis that a delay between biopsy and radical surgery of breast cancer is an important prognostic factor.
