Breast Cancer Nomogram to Predict Benefit of Radiation for Older Patients With Breast Cancer Treated With Conservative Surgery


This software calculates the benefit of radiation for older patients with breast cancer treated with conservative surgery. This nomogram was developed at the University of Texas MD Anderson Cancer Center and has not yet been externally validated.

Select age between 66 and 79.
Select race.
Select tumor size.
Select estrogen receptor status.
Select nodal status.
Pathologically-confirmed node-negative refers to lymph node-negative disease that has been confirmed by axillary lymph node dissection or sentinel lymph node evaluation. Clinically-assessed node-negative refers to negative axillary nodes by physical examination and/or imaging without pathologic confirmation. Pathologically-confirmed node-positive refers to lymph node-positive disease that has been pathologically assessed and confirmed.
