Background: This systematic review investigated the impact of complications on long term outcomes for patients with primary invasive operable breast cancer. Methods: A systematic review was performed using appropriate keywords, and meta-analysis using a random effects model completed. Results: Ten retrospective cohort studies, including 37657 patients were included. Five studies identified a relationship between wound complications, infection and pyrexia and recurrence or recurrence-free survival. Risk of recurrence, 1-year and 5-year recurrence-free survival and overall survival were related to complications, particularly for patients with poor Nottingham Prognostic Index. Five studies failed to demonstrate a relationship between complications and prognosis. Complication was found to significantly affect 5-year recurrence-free survival (HR 1.48 95% CI 1.02-2.14, p = 0.04) but not recurrence (HR 2.39, 95%CI 0.94-6.07, p = 0.07), with a high degree of heterogeneity among analysed studies (I2 = 95%). Discussion: Further research is needed to quantify the effects of postoperative complication on prognosis following surgery for breast cancer.
