Good Prediction of the Likelihood for Sentinel Lymph Node Metastasis by Using the MSKCC Nomogram in a German Breast Cancer Population

Background The sentinel lymph node (SLN) procedure could be omitted in cases of accurate prediction of very high or very low probability of SLN metastasis in early breast cancer patients. We evaluated a breast cancer nomogram, an online tool provided by the Memorial Sloan–Kettering Cancer Center (MSKCC), that predicts the likelihood of a positive lymph node.
