%0 Journal Article %T Endoscopy-assisted breast-conserving surgery for breast cancer patients %A Masahiro Ohara %A Shinji Ozaki %J SCIE-indexed Journal %D 2014 %X Breast-conserving surgery (BCS) combined with postoperative radiotherapy is widely accepted as standard therapy for early breast cancer patients with survival equivalent to that of mastectomy (1-3). Moreover, oncoplastic breast cancer surgery techniques have developed over the recent years, and patients¡¯ concern regarding the postoperative aesthetic outcome has also been increasing. Therefore, the current goal of BCS is not only to achieve a curative partial resection but also to preserve the cosmetic appearance of the breast. Endoscopy-assisted breast conserving-surgery (EBCS), which has the advantage of a less noticeable scar, was developed more than ten years ago and performed in some Asian countries (4-13). Although a shortage of clinical studies exists, achievement of oncological safety, as well as better cosmetic outcomes, with EBCS has been demonstrated in some institutions recently. However, achieving both tasks (curative operation and satisfaction with the aesthetic outcome) together with EBCS can be challenging and sometimes result in failure because of difficulty in repairing the excised breast volume. In this article, we will review the EBCS clinical studies that have been conducted so far and discuss current issues regarding this operative method %U http://gs.amegroups.com/article/view/3628/4711
