Abstract
BACKGROUND: The resection of tumors in small breasts or in areas such as the upper and inner parts of the breast may have disabling cosmetic results. Tumor resection reduces the volume of the breast and may result in asymmetry or distortion of the nipple-areola complex. Autologous fat transfer/grafting has been shown to be a reliable technique for improving these poor cosmetic results. This study aimed to evaluate the feasibility, complications, and cosmetic outcomes of immediate autologous fat grafting during breast-conserving surgery (BCS) in Chinese patients with early-stage breast cancer. METHODS: This retrospective study included 58 patients with early breast cancer treated by the same surgical team from October 2016 to May 2017. The patients were divided into two groups: BCS with lipofilling (experiment group, n=30) and BCS without lipofilling (control group, n=28). All patients received the recommended breast cancer treatment with complementary radiotherapy. The follow-up period after the completion of radiotherapy ranged from 36-44 months. The resected and grafted volumes, complications, esthetic results, patient satisfaction, and recurrence rate within 3 years were compared between the groups. RESULTS: The average resected and grafted volumes in the lipofilled group were 47 and 74 mL, respectively, with only one seroma and no other complications. Regarding physician evaluation, BCS with lipofilling resulted in better cosmetic outcomes than BCS without lipofilling (33% versus 15%, respectively). Poor responses occurred in only 7% of patients with lipofilling, compared with 15% without lipofilling. Regarding patient self-evaluation, Breast-Q scores including patient satisfaction with their breasts and psychosocial well-being, were significantly higher in patients who received lipofilling compared with non-lipofilled patients. Regional recurrence occurred in one patient (case 21) (3.7%) in the lipofilling group and systemic recurrence occurred in one patient (case 12) (3.8%) in the control group. CONCLUSIONS: Immediate autologous fat grafting is a promising, effective, and convenient technique for partial breast reconstruction after BCS, with potentially higher levels of patient and physician satisfaction compared with traditional BCS.
