A clinical trial of curative surgery under local anesthesia for early breast cancer

摘要

The traditional method of surgical management of primary breast cancer has been radical mastectomy. Over the years, however, this aggressive approach has changed to a more conservative one. And now breast-conserving surgery (BCS) is the standard method. This advance was supported by the spread of breast cancer screening, the improvement of imaging methods and other developments. Moreover, the sentinel lymph node biopsy (SLNB) was developed for axillary staging (1-3). As a result, the number of cases that can avoid axillary lymph node dissection is increasing. We considered it was possible that less-invasive methods of curative management of breast cancer would be developed. Therefore, we introduced BCS with SLNB under local anesthesia (LA) for patients with early breast cancer. The aims of this article are to report our experience with BCS with SLNB performed with LA and to demonstrate the feasibility and oncological safety of this procedure,
