Breast cancer surgery in 30 Italian general hospitals.

The utilization of limited surgery in patients with breast cancer operated between September 1986 and July 1988 was assessed using information collected within a cohort subsequently enrolled in a randomized clinical trial testing the efficacy of post-surgical follow up. Overall 30% had limited surgery, 61% had other more radical procedures and 9% are still undergoing an unnecessary Halsted mastectomy. Several factors were related to the lower likelihood of getting a conservative procedure: geographic distribution, age, level of education, quadrant and nodal state. The paper discusses the implications of these findings in view of the otherwise growing consensus that more radical surgery should be abandoned.
