The optimal treatment strategy for patients with small human epidermal growth factor receptor 2 (HER2)‐positive tumors is based on nodal status. The authors’ objective was to evaluate pathologic nodal disease (pathologic lymph node‐positive [pN‐positive] and pathologic lymph node‐positive after preoperative systemic therapy [ypN‐positive]) rates in patients who had clinical T1–T2 (cT1–cT2)N0M0, HER2‐positive breast cancer treated with upfront surgery or neoadjuvant chemotherapy (NAC).
