Key clinical point: In women with locally advanced breast cancer (LABC) who received neoadjuvant treatment (NAT) followed by breast surgery, the type of breast surgery, pathological complete response (pCR), body mass index (BMI), and pretreatment stage of tumors were the significant predictors of survival outcomes.
Major finding: Overall survival was significantly improved in patients with LABC who did vs did not achieve pCR (odds ratio [OR] 0.42; P = .008). However, it was much worsened in patients who underwent mastectomy vs breast-conserving surgery (BCS; OR 1.678; P = .024), had higher vs lower BMI (OR 1.031; P = .017), and had stage IIIB or IIIC vs IIB tumors (OR 2.450; P < .001).
Study details: Findings are from a retrospective cohort study including 530 patients with LABC, of which 24.6% of patients underwent BCS after receiving NAT.
Disclosures: This study did not receive any funding. The authors declared no conflicts of interest.
