ABSTRACT
Objective:To discuss the oncologic safety, aesthetic outcome, and upper extremity function of single-port insufflation endoscopic nipple-sparing mastectomy (SIE-NSM) in the treatment of early breast cancer.Methods:From January 2014 to August 2019, a total of 80 patients with stage Ⅰ and Ⅱ breast cancer underwent SIE-NSM, at Beijing Friendship Hospital, Capital Medical University were retrospectively analyzed and followed up. Estimated the oncologic safety, aesthetic outcome, and upper extremity function.Results:SIE-NSM was performed successfully on all 80 patients.There was no serious complication after surgery.The follow-up time was 16-82 months and the median follow-up time was 42 months. Local recurrence occurred in two patients, and there was no distant metastases. Four (5%) patients developed grade 1-3 nipple-areola complex ischemia. There were no cases of subcutaneous effusion.The satisfaction with breasts, chest well-being, psychosocial well-being, and sexual well-being scores were confirmed to be highly rated by Breast-Q scale. Upper extremity function score confirmed that good upper limb function was preserved after surgery. The mean length of incision was (3.6±0.8) cm, and the blood loss was (24.7±19.3) mL.Conclusions:SIE-NSM can achieve a higher cosmetic score and a better recovery of upper limb function on the premise of ensuring the safety of the tumor.This novel method is an appropriate surgical option for patients with early breast cancer.
