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.

Enter current age, in years. Must be between 22 and 99.
Indicate whether the breast tumor is located only in the upper inner quadrant (UIQ).
Choose the histologic type of the tumor. The "Other" category includes mucinous, tubular, papillary and medullary tumors.
Size of the primary tumor, in centimeters, on preoperative imaging studies.
Indicate whether tumor was located in more than one location in the breast.
Indicate whether tumor cells were present in blood vessels or lymphatic structures.
Indicate whether the tumor is negative for expression of estrogen receptor (ER), progesterone receptor (PR) and HER/2 neu. Select "YES" if tumor is negative for all three and select "NO" if tumor is positive for any one, or more, of these markers.
