Breast Cancer Nomogram: Sentinel Lymph Node Metastasis

This nomogram can be used to help newly diagnosed breast cancer patients assess the likelihood that their breast cancer has spread to the sentinel lymph nodes.

CalculateClearEnter Your Information

Enter current age. Must be between 20 and 91.
 (20 to 91 yrs)
Size of the primary tumor (as measured either in imaging study or pathological exam), in centimeters.
 (0.1 to 11.0 cm)
Check box if tumor has been pathologically defined as pure tubular, pure colloid (mucinous), or typical medullary carcinomas on the pathology report. Other histologies such as atypical medullary carcinoma or carcinoma with ductal and lobular features should be classified as ductal -- see Tumor Type and Grade section below for more details.
Check box if tumor is confined within the upper inner quadrant (UIQ) of the breast.
Select YES if one or more tumor cells found in the blood or lymphatic vessels.
Select YES if breast cancer has cancer cells seperated from the main tumor mass.
Indicate if tumor type is ductal or lobular, as noted in the pathology report. If ductal, indicate the nuclear grade -- I: slight or no variation in the size and shape of the nucleus; II: moderate variation in the size and shape of the nucleus; III: marked variation in the size and shape of the nucleus.
Select NEGATIVE if estrogen receptors stain positive in <10% of cells; select POSITIVE if estrogen receptors stain positive in ≥10% of cells.
Select NEGATIVE if progesterone receptors stain positive in <10% of cells; select POSITIVE if progesterone receptors stain positive in ≥10% of cells.

Predicted Probability of Spread to Sentinel Lymph Nodes

This nomogram helps physicians and patients to accurately predict the likelihood that a patient’s breast cancer has spread to the sentinel lymph nodes. The calculated estimates include the risk of any tumor cells being found in the nodes, including isolated tumor cells seen only on immunohistochemistry.
