Sentinel Node Biopsy in Breast Cancer

This is a guideline for patients who have been diagnosed with cancer of the breast and meet the selection criteria for sentinel lymph node biopsy (SLNB). The guideline reviews SLNB versus axillary lymph node dissection (ALND) and provides recommendations on patient selection, optimal technique for the use of SLNB, and surgical training. Recommendations are provided for managing challenging situations including ALND when SN is positive, intraoperative assessment of SN(s), ductal carcinoma in situ (DCIS), and multiple sentinel nodes.
