BackgroundImmediate breast reconstruction is safe from an oncological perspective, but the relatively high rate of postoperative complications raises oncological concerns. The present study aimed to evaluate the potential influence of postoperative complications after immediate breast reconstruction on breast cancer recurrence and survival.MethodsPatients with breast cancer who had total mastectomy and immediate reconstruction between 2008 and 2013 were followed for at least 5 years. The impact of postoperative complications on oncological outcomes was assessed using multivariable Cox regression analyses.ResultsIn total, 438 patients with a median follow-up of 82 months were analysed. Five-year local recurrence-free, disease-free and overall survival rates were 95·4, 93·1 and 98·4 per cent respectively. Postoperative complications developed in the operated breast in 120 patients (27·4 per cent) and at other sites (flap donor) in 30 patients (6·8 per cent). Development of breast complications was associated with significantly increased rate of recurrence compared with no complications (16·7 versus 5·9 per cent; P = 0·002). In multivariable analysis, patients with breast complications had significantly worse disease-free survival than those with no complications (hazard ratio (HR) 2·25; P = 0·015). This remained significant in patients who received adjuvant therapy without delay (8 weeks or less after surgery) (HR 2·45; P = 0·034).ConclusionDevelopment of postoperative complications in the breast can have a negative impact on survival and recurrence after immediate reconstruction.© 2020 BJS Society Ltd Published by John Wiley & Sons Ltd.
