Invasive disease‐free survival (IDFS) rates are excellent in patients with breast cancer (BC) with hormone receptor‐positive (HR+), human epidermal growth factor receptor 2‐negative (HER2‐), axillary lymph node‐negative (LN‐) tumors with a 21‐gene expression assay recurrence score (RS) of 0 to 10. However, to the authors' knowledge, the outcomes among patients with an RS of 11 to 25 who are treated with endocrine therapy alone are unknown.
