What is the feasibility of upfront sentinel lymph node biopsy (SLNB) and the rate of axillary lymph node dissection (ALND) among patients with HR+/HER2− cN1 breast cancer selected with axillary ultrasound?In this nonrandomized clinical trial including 78 consecutive patients with cTx/cT1-2 cN1 HR+/HER2− breast cancer with palpable, biopsy-proven nodal metastases, SLNB was feasible among patients with cN1 HR+/HER2− disease, with 3 or more SLNs retrieved in 96% of cases, and nearly 70% of patients meeting criteria for SLNB alone and able to avoid ALND.This approach affords the opportunity to omit ALND and minimize morbidity among cN1 patients with limited nodal disease burden.
