Breast Cancer IndexSM
Breast Cancer Index refines risk stratification in patients with estrogen receptor (ER)-positive, lymph node-negative breast cancer, providing independent and complementary prognostic information.
Of the 86% of patients identified by St. Gallen Risk Criteria as intermediate risk in a recent study1, only 26.5% were actually intermediate risk: 42.5% were low risk and 31% were high risk when re-stratified using the Breast Cancer Index.
