Oncologic safety of autologous fat grafting in primary breast reconstruction after mastectomy for cancer.

Introduction: Autologous fat transfer (AFT) is widely used to improve results of breast reconstructive surgery, but its safety is controversial. Our objective was to evaluate the oncologic safety of AFT in a homogeneous population of patients who underwent a total mastectomy with immediate reconstruction for breast cancer.

Methods: We performed a retrospective cohort study by identifying all patients who underwent immediate breast reconstruction after mastectomy for breast cancer from 2007 to 2015 in our center.
