Conservative surgery and radiotherapy for early breast cancer.

In 1984, as part of a prior American Cancer Society National Conference on Breast Cancer, the authors reported on the status of conservative surgery (CS) and radiotherapy (RT) as primary local treatment for women with early stage breast cancer. Since that time, additional data have become available regarding the use of this approach and its comparability to mastectomy. In general, these data support the use of CS and RT and, as a result, this approach is now more widely employed in the United States and abroad than it was in 1984. The current focus of inquiry has shifted from whether or not CS and RT is an acceptable option for patients with early stage breast cancer to the following questions. For which patients are CS and RT suitable? What are the best techniques of surgery and RT? Are there any patients who can be treated safely with CS without RT? How should RT and systemic therapy be integrated when both are to be used? In this report, recent results on the use of CS and RT from both retrospective and prospective trials are summarized, and these current areas of inquiry are addressed.
