Key clinical point: A first-line chemotherapy-free treatment regimen containing endocrine therapy (ET) and human epidermal growth factor receptor 2 (ERBB2)-targeted therapy led to excellent survival outcomes in patients with hormone receptor-positive (HR+) and ERBB2-positive (ERBB2+) metastatic breast cancer (BC).
Major finding: No significant difference was observed in overall survival (hazard ratio [HR] 1.03; P = .80) or progression-free survival (HR 1.00; P > .99) between patients receiving ERBB2-targeted therapy and chemotherapy with or without ET and patients receiving ERBB2-targeted therapy with ET only, regardless of the type of ERBB2-targeted therapy.
Study details: Findings are from a cohort study including 1723 patients with HR+/ERBB2+ metastatic BC who received ERBB2-targeted therapy and chemotherapy with or without ET (n = 1520) or ERBB2-targeted therapy with ET only (n = 203).
