Endoscopic nipple sparing mastectomy with immediate implant-based reconstruction versus breast conserving surgery: a...

To evaluate the differences between endoscopic nipple sparing mastectomy (ENSM) with immediate implant-based reconstruction and breast conserving surgery(BCS) applied to early-stage breast cancer in postoperative outcomes, function, and cosmesis. we made a prospective, non-randomized study reviewed a total of 346 cases of breast cancer from January 2007 to December 2011, including 189 cases of BCS and 157 cases of ENSM. All the patients were followed up to April 2016, with a median follow-up time of 74 months. The operative time, blood loss and drainage, postoperative complications, postoperative cosmesis, local recurrence rate, disease-free survival rate and overall survival rate of the two groups were compared. we found out that the operative time of ENSM was longer than that of BCS. There was no difference in blood loss and drainage, the postoperative complications, the disease-free survival rate and overall survival rate between the two groups. In regarding to cosmesis, patients in the ENSM group were more likely to get a satisfactory postoperative breast appearance. we reached a conclusion that ENSM is a safe and effective operative method retainingadvantages of TSSM to further improve the postoperative cosmetic effect, without increasing other risks. The surgery provides a new choice for patients with early-stage breast cancer.
