The use of reduction mammaplasty with breast conservation therapy: an analysis of timing and outcomes.

Abstract

Oncoplastic reduction mammaplasty is often used to prevent or correct breast conservation therapy deformities. The purpose of this review was to evaluate surgical outcomes, patient satisfaction, and aesthetic outcomes of this procedure when performed before or after radiation therapy. Breast cancer patients treated with breast conservation therapy and reduction mammaplasty between 2005 and 2012 were divided into immediate reconstruction, delayed immediate reconstruction, and delayed reconstruction. Greater than 6-month follow-up was required for inclusion. Patient demographics and clinical outcomes, including complications, patient satisfaction, and aesthetic result, were queried. Patient satisfaction was determined using the BREAST-Q survey. Postoperative photographs were used to rate aesthetic outcomes blinded to the timing of the procedure. Patients in the immediate reconstruction group had fewer complications (immediate reconstruction, 20.5 percent; delayed immediate reconstruction, 33.3 percent; delayed reconstruction, 60.0 percent; p < 0.001) and asymmetry (immediate reconstruction, 8.5 percent; delayed immediate reconstruction, 44.4 percent; delayed reconstruction, 24.0 percent; p < 0.001), and required fewer procedures to complete the reconstruction (immediate reconstruction, 1.2; delayed immediate reconstruction, 2.4; delayed reconstruction, 2.2; p < 0.001). Delayed reconstruction resulted in higher complication and fat necrosis rates (immediate reconstruction, 0.9 percent; delayed immediate reconstruction, 0.0 percent; delayed reconstruction, 8.0 percent; p = 0.047). Although patient satisfaction and aesthetic outcomes were better in the immediate reconstruction group, this difference was not statistically significant. Oncoplastic reduction techniques performed before radiation therapy result in fewer complications. Good patient satisfaction and aesthetic outcomes can be achieved when reduction is performed before or after radiation therapy, but patient selection and education are important. Therapeutic, III.
