Key clinical point: Neoadjuvant radiation therapy (NART) led to similar survival outcomes as postoperation radiation therapy (PORT) in patients with invasive ductal carcinoma (IDC) who underwent breast-conserving surgery (BCS) and were treated with neoadjuvant chemotherapy.
Major finding: NART vs PORT led to comparable breast cancer-specific survival (BCCS) and overall survival (OS) outcomes (both log-rank P > .05) in patients undergoing BCS or implant-based immediate breast reconstruction. However, NART vs PORT led to significantly lower BCCS (hazard ratio [HR] 1.407; log-rank P = .003) and OS (HR 1.383; log-rank P = .004) outcomes in those undergoing mastectomy.
Study details: This retrospective study included 14,515 women with IDC (age ≤ 80 years) from the Surveillance, Epidemiology, and End Results (SEER) database who were treated with neoadjuvant chemotherapy, of whom 386 and 14,129 patients underwent NART and PORT, respectively.
Disclosures: This study was supported by Shanghai Science and Technology Commission and Fudan University, China. The authors declared no conflicts of interest.
