Oncological safety of oncoplastic breast conserving surgery-compare with conventional breast conserving surgery and total mastectomy.

e12531Background: In recent decades, the surgical management of breast cancer has steadily and considerably improved. Now oncoplastic technique applies to breast-conserving surgery (BCS) allows large-volume resection without compromising oncological safety. A satisfactory cosmetic result could be difficult to obtain due to high tumor to breast size ratio, unfavorable location, close to the nipple and contralateral ptosis. Oncoplastic techniques allows the performance of wide excision, conserving an excellent breast shape, may be helpful in many cases. This study was aimed to evaluate the oncological safety of oncoplastic surgery for primary breast cancer. Methods: We compared 1320 consecutive patients who underwent surgery between August 2011 and December 2014 for breast cancer at Seoul National University Hospital by one experienced surgeon. Retrospectively medical chart review was done and patients divided into three groups. Among them 42.65% (n = 563) underwent oncoplastic surgery (OPS), 49.70% (n = 65...
