- EndoPredict provides an individualized probability of early and late recurrence for each patient based on their tumor’s biology and pathology. With the integration of these specific features, EndoPredict also accurately predicts an individualized absolute chemotherapy benefit to help make the right treatment decisions for each individual case of breast cancer.
Target population:
Help
Women with early-stage breast cancer with the following characteristics: ER+, HER2-, node negative or node positive (up to 3 nodes).

Test Procedure:
Help
Quantitative RT-PCR is used to measure, in triplicate, the expression of 8 signature genes, and 3 normalization genes, with 1 control gene to assess for DNA contamination. These molecular data are used to generate a 12- Gene Molecular Score. If tumor size and lymph node status are unavailable at the …
