Sentinel Lymph Node Micrometastasis and Risk of Non-Sentinel Lymph Node Metastasis: Validation of Two Breast Cancer Nomograms

In our results the MSKCC nomogram did not provide a reliable predictive model for identifying patients with low risk of non-SLN metastasis in the event of micrometastasis in SLN. Our validation study shows that the Tenon score is more accurate and useful in patients with micrometastasis in SLN.
