Feasibility and Prognostic Effect of Sentinel Lymph Node Biopsy After Neoadjuvant Chemotherapy in Cytology-Proven, Node-Positive Breast Cancer

SLNB may be feasible after NAC for node-positive breast cancer and may help reduce surgical morbidity by avoiding the need for standard axillary lymph node dissection in some patients. We suggest that future studies with a large number of patients and a longer follow-up period are necessary to support the use of SLN surgery as an alternative to axillary lymph node dissection in this patient population.
