Safety of Reduction Mammaplasty and Mastopexy After Breast Conservation Therapy and Radiation Therapy A Case Series

BackgroundConservative surgery and radiotherapy (CS + RT) have become the standard of care for early-stage breast cancer as an alternative to mastectomy. With the increasing rate of obesity and incidence of macromastia, surgeons increasingly encounter patients with a history of breast radiation desiring breast reduction. However, elective breast surgery after irradiation remains to be controversial due to known adverse effects of radiation, especially on wound healing, and unknown effects of lumpectomy on traditional pedicle choices. Herein, we present our experiences and outcomes of reduction mammaplasties and mastopexies in patients with breast cancer previously treated with CS + RT.MethodsBetween 2009 and 2020, 13 patients undergoing reduction mammaplasty or mastopexy, who have previously underwent CS + RT with or without axillary surgery, were included in this study. Surgical techniques and complications, including delayed wound healing, infection, fat necrosis, and nipple-areolar necrosis, were recorded and analyzed based on the irradiated versus nonirradiated sides.ResultsOf the 13 patients, delayed wound healing occurred in 7% on the irradiated side and 15% on the nonirradiated sides (P > 0.05). No significant correlation was observed between the number of complications and time of elective breast surgery from the last radiation therapy. Complications between irradiated and nonirradiated breasts did not significantly differ in both the reduction mammaplasty and mastopexy groups.ConclusionsReduction mammaplasty and mastopexy in patients with a history of lumpectomy and breast irradiation can be safely performed and should be considered in those experiencing macromastia or asymmetry post-CS + RT.
