BACKGROUND: The aim of the study is to demonstrate the feasibility and the oncologic effectiveness of quadrantectomy plus sentinel node biopsy performed under local anesthesia, and to demonstrate the economic and psychologic advantages. METHODS: From October 1996 to March 2000, 71 @entity1 affected with clinical T1 N0 @entity0 , underwent quadrantectomy or @entity5 resection plus sentinel node biopsy and clinically suspicion axillary nodes biopsy, under local anesthesia at the @entity13389 di Cura "Villa Mafalda" in Rome. RESULTS: Twenty @entity5 were T1a, 26 T1b e 25 T1c. A mean of 2 sentinel nodes (range 1-4) and a mean of 8 axillary nodes were removed during the procedure. In 2 cases sentinel nodes were not identified. Intraoperative histologic examination showed metastatic sentinel nodes in 11 cases. An axillary node dissection was performed in all cases (>12 nodes) and no other metastatic nodes were found. In all @entity1 clinically suspected nodes were removed. In two cases no evidence of @entity3 was found in sentinel nodes, while histologic examination revealed in a @entity1 micrometastasis in one node, and in another @entity1 two metastatic nodes. CONCLUSIONS: Fifty-three @entity1 rated the overall surgical, anesthetic and recovery experience as "very satisfactory", 13 "satisfactory" and 5 "unsatisfactory". @entity1 typically expressed their pleasure at the possibility to return home and stressed the ease of recovery.
