Surgical considerations for breast-conserving therapy in patients undergoing neoadjuvant chemotherapy for early-stage breast cancer
According to the National Cancer Comprehensive Network guidelines patients with breast tumours [less-than-or-equal]1 cm should be offered systemic therapy. Multiple studies, however, have demonstrated no survival advantage between giving chemotherapy before (neoadjuvant) or after (adjuvant) surgery. There are, however, certain benefits that can be derived from patients who undergo neoadjuvant chemotherapy. Such benefits include better stratification of the patient's prognosis based on tumour and nodal response, and converting patients from mastectomy-only candidates to breast-conserving surgery candidates. Due to these advantages, many patients with early-stage breast cancer will undergo neoadjuvant chemotherapy and the surgical issues must be considered for patients who are treated in such a manner to guarantee optimal outcomes. Issues that will be discussed are the surgical preoperative evaluation, extent and timing of local resection of both the breast and regional nodes and finally, the potential future effects of this multi-modality therapy.(Received October 21 2004)
