Breast Cancer Nomogram to Predict Positive Sentinel Lymph Nodes, without Neoadjuvant Chemotherapy

This software calculates the probability of finding positive sentinel lymph nodes in breast cancer patients who have not had neoadjuvant (preoperative) chemotherapy. This nomogram was developed at the University of Texas MD Anderson Cancer Center and has been externally validated.
