Key clinical point: Patients with metastatic breast cancer (BC) with a lobular subtype may have worse outcomes compared with those with a ductal subtype.
Major finding: Invasive lobular carcinoma (ILC) vs. invasive ductal carcinoma (IDC) subtype was significantly associated with worse survival (hazard ratio [HR] 1.31; P < .0001) and progression-free survival (HR 1.15; P < .0001).
Study details: Findings are from a retrospective analysis of 13,111 patients with metastatic BC with ILC (13.8%) or IDC (86.2%) subtype from the UNICANCER Epidemiological Strategy and Medico Economics (ESME)-metastatic BC cohort.
