Abstract
Introduction: The rate of nodal positivity (ypN+) after neoadjuvant chemotherapy in patients diagnosed with node-negative (cN0) breast cancer is low. Sentinel lymph node biopsy (SNLB) may be of limited value in select patients. The aim of this study was to determine the rate of axillary ypN0 in patients with cN0 disease treated with neoadjuvant chemotherapy (NACT) and to identify clinicopathological features associated with ypN0.
