Risk Factors for Delays in Adjuvant Chemotherapy Following Immediate Breast Reconstruction

Background: Concerns exist that immediate breast reconstruction may delay adjuvant chemotherapy initiation, impacting oncologic outcomes. Here, we determine how post-operative complications impact chemotherapy timing, and identify factors associated with greater risk for delays. Methods: Retrospective chart review identified patients undergoing immediate breast reconstruction and adjuvant chemotherapy at a single institution from 2010 to 2015. Patients were analyzed based on occurrence of post-operative complications and time to chemotherapy. Results: A total of 182 patients (244 breast reconstructions) were included in the study; 210 (86%) reconstructions did not experience post-operative complications, 34 (13.9%) did. Patients who experienced post-operative complications had a higher mean age (53.6 vs. 48.1 years, p=0.002), and higher rates of diabetes (23.5% vs. 3.8%, p48.5 days were of higher mean age (55.9 vs. 50.7 years, p=0.074), had increased rates of diabetes (36.8% vs. 6.7%, p=0.053), and immediate autologous reconstruction (31.6% vs. 0%, p=0.027). A predictive model based on these findings determined that patients with at least 1 of these 3 risk factors have a 74% chance of experiencing prolonged times to chemotherapy initiation vs. 18% without risk factors (p=0.003). Conclusions: Risk factors for delayed chemotherapy in the context of post-operative complications are age >51.7 years, diabetes, and autologous reconstruction. Reconstructive candidates who fit this profile are at highest risk and merit extra consideration and counseling. * Authors contributed equally to preparation of this manuscript FINANCIAL DISCLOSURES: None of the authors of this manuscript have commercial associations or financial disclosures to report that create a conflict of interest with information presented in this manuscript.
