Reoperations occur frequently after initial lumpectomy for breast cancer. The authors hypothesized that the receipt of neoadjuvant chemotherapy (NAC) is associated with fewer reoperations.


The association between timing of chemotherapy and reoperation rates (ROR) after lumpectomy was investigated for patients with stages 1–3 breast cancer in the National Cancer Database (NCDB) from 2010 to 2013 by multivariable logistic regression modeling. Then propensity score-matching was performed.


The unadjusted ROR for 71,627 stages 1–3 patients was 11.4% for those who had NAC compared with 20.3% for those who had postoperative chemotherapy (p < 0.001) (odds ratio [OR] 0.53; 95% confidence interval [CI] 0.49–0.57; p < 0.001). The ORs for the reoperations performed for patients with stages 1, 2, and 3 cancers who received NAC were respectively 0.65 (95% CI 0.56–0.75), 0.50 (95% CI 0.45–0.56), and 0.27 (95% CI 0.19–0.38) The p values for all were lower than 0.001.


For a population of patients receiving chemotherapy, the receipt of chemotherapy before instead of after surgery was associated with fewer reoperations after initial lumpectomy for breast cancer.
