Oncoplastic Reconstruction in the Setting of Prior Cosmetic Augmentation.

Abstract

Background: This study explored the surgical management and reconstruction options for augmented breasts in the context of breast conservation therapy (BCT) for breast cancer. The authors hypothesized that there would be no difference in the rates of complications, revisions, or patient satisfaction in patients who maintained their breast augmentation versus those who had their implants removed in the context of BCT.

Methods: The authors conducted a retrospective review of 142 patients who underwent BCT at a single center from March of 2016 to March of 2022. The study included patients who had a preexistent cosmetic augmentation at the time of breast cancer diagnosis and BCT. Patient demographics, clinical and treatment characteristics, breast implant details, reconstructive technique, complications, and revisions were recorded. Patient-reported outcomes were assessed using the BREAST-Q BCT module.

Results: Ninety-three patients (65.5%) chose to maintain their implants, whereas 49 (34.5%) elected to have them removed during BCT. Patients with submuscular implants were more likely to maintain their implants. Oncoplastic mastopexy was associated with higher complication rates, particularly in patients opting for implant downsizing. However, multivariate logistic regression did not identify implant management strategy as an independent predictor for complications or revisions. Surgical-site infection was the only predictor of implant explantation. Patient-reported outcomes did not differ significantly between the different implant management cohorts.

Conclusions: This study demonstrates that maintaining breast implants during BCT does not increase the risk of complications or revisions. Overall, BCT in augmented women was found to be a safe approach, with high patient satisfaction.

Clinical question/level of evidence: Risk, III.
