Evaluation of Three Scoring Systems Predicting Non Sentinel Node Metastasis in Breast Cancer Patients with a Positive Sentinel Node Biopsy

Background Completion axillary lymph node dissection (cALND), performed after a positive sentinel lymph node biopsy (SLNB) in breast cancer patients, often results in no additional positive nodes. Scoring systems have been published to aid in the prediction of nonsentinel node metastasis. Our purpose was to assess the validity of these scoring systems in our patient population.
