Background: It is debated whether all patients with a positive sentinel node dissection (SLND) should be submitted to axillary lymph node dissection (ALND). Models have been developed to estimate the likelihood of nonsentinel node (non-SLN) metastases. Methods: The accuracy of the Memorial Sloan-Kettering Cancer Center (MSKCC) nomogram and MD Anderson scoring system for the prediction of non-SLN status was tested in a consecutive series of 186 SLN-positive breast cancer patients. A multivariate analysis was performed to assess which parameters independently predicted the presence of non-SLN metastases. Results: The predictive accuracy of the MSKCC nomogram measured by the receiver operating characteristic curve was 0.71, and it was best in patients with
