Several statistical models have been developed to predict the likelihood of finding additional axillary nodal disease when the sentinel lymph node is found to harbor breast cancer. Hessman and colleagues1 have presented an analysis of the accuracy of nomograms from Memorial Sloan-Kettering Cancer Center (MSKCC) and Stanford in predicting nonsentinel lymph node metastasis in patients with breast cancer treated at the Oregon Health & Science University from October 1, 1999, through January 31, 2008, that had positive sentinel node biopsies and subsequent axillary lymph node dissection.
