Abstract

Abstract: Invasive lobular carcinoma (ILC) has a different treatment response from invasive ductal carcinoma (IDC). We assessed whether perioperative chemotherapy was associated with improved prognosis in patients with ILC. Retrospective data of women who underwent surgery for ILC were extracted from the SEER database. Subjects were divided into non‐chemotherapy and chemotherapy groups. Overall, 10 537 patients were included, and 2107 patients were stratified into each group after propensity score matching. Perioperative chemotherapy significantly improved 10‐year survival rates for ILC, particularly in patients with large tumor size and lymph node metastases. Perioperative chemotherapy is effective for ILC patients with proper selection.
