Abstract: Objective To investigate the clinical effect and safety of“人”- shaped glandular tissue flap oncoplastic technique in breast-conserving surgery for early breast cancer. Methods The clinical data of 78 female patients who received breast-conserving surgery using“人”-shaped glandular tissue flap oncoplastic technique from March 2017 to December 2019 were analyzed retrospectively, and its clinical effects and complications were summarized and analyzed. Results The duration of operation was 65-175 min, with an average time of 98 min; the volume of tissue resected tissue was 47-214 mm3, with an average of 124.3 mm3; the incisal margins of 2 patients showed positive results in the initial cryophistopathological examination, but the incisal margins were confirmed to be negative in intraoperative cryophistopathological examination and postoperative paraffin pathological examination after next resection; 2 patients were removed the nipple-areola complex because the tumor was located in the nipple and areola areas, and incisal margins were positive. In the evaluation of patients' satisfaction with breast cosmetic effect 3 months after operation showed that 71 patients (91.0%) were very satisfied, 6 patients(7.7%) were satisfied, 1 patient(1.3%) was general and no dissatisfied patients were found, with an overall satisfaction rate of 98.7%. In the objective evaluation by specialists with breast cosmetic effect 3 months after operation showed that there were 69 excellent cases(88.5%), 8 good cases(10.3%), and 1 general case (1.3%). Postoperative complications occurred in a total of 3 patients, including 1 case of  postoperative incision infection, 1 case of local subcutaneous, and 1 case of partial nipple and areola ischemia, the complication rate was 3.8%, and all recovered after symptomatic treatment without delay of postoperative adjuvant treatment. Conclusions The breast-conserving surgery using “人”-shaped  glandular tissue flap oncoplastic technique has a low incidence of postoperative complications and a satisfactory cosmetic effect.
