Abstract

Background: Oncoplastic breast-conserving surgery expands the indications for breast conservation. When performed using modified mastopexy/breast reduction techniques, the optimal timing of the contralateral symmetrizing mastopexy/breast reduction remains unclear. This study examined the effect of the timing of symmetrizing mastopexy/breast reduction on oncoplastic breast-conserving surgery outcomes.

Methods: A retrospective study was conducted of all patients who underwent oncoplastic breast-conserving surgery using mastopexy/breast reduction techniques at a single center from 2010 to 2016. Patients who received synchronous (immediate) contralateral breast symmetrizing mastopexy were compared with those who underwent a delayed symmetrizing mastopexy procedure. Demographic, treatment, and outcome data were collected. Descriptive statistics were used and multivariate analysis was performed to evaluate the various relationships.

Results: There were 429 patients (713 breasts) included in the study; of these, 284 patients (568 breasts) underwent oncoplastic breast-conserving surgery involving mastopexy/breast reduction techniques and immediate symmetrizing mastopexy, and 145 patients underwent delayed contralateral symmetrizing mastopexy. The overall complication rate was similar between the immediate and delayed groups (25.4 percent versus 26.9 percent, respectively; p = 0.82), as was the major complication rate (10.6 percent versus 6.2 percent; p = 0.16). Complications resulted in a delay in adjuvant therapy in 18 patients (4.2 percent); in two patients (0.7 percent), this delay resulted from a complication in the contralateral symmetrizing mastopexy breast. Immediate contralateral symmetrizing mastopexy was not associated with increased risk of complications per breast (p = 0.82) or delay to adjuvant therapy (p = 0.6).

Conclusion: Contralateral mastopexy/breast reduction for symmetry can be performed at the time of oncoplastic breast-conserving surgery in carefully selected patients without significantly increasing the risk of complications or delay to adjuvant radiation therapy.

Clinical question/level of evidence: Therapeutic, III.
