EndoPredict Breast Cancer Prognostic Test – the most accurate second generation prognostic and predictive early-stage breast cancer test

Myriad Genetics’ EndoPredict Breast Cancer Prognostic Test is a gene expression test for early-stage ER-positive/HER2-negative breast cancer. It provides highly accurate prediction of early and up to 15 years risk of distant breast cancer recurrence along with treatment benefit.1-3

This second generation breast cancer test is trusted worldwide to help guide confident adjuvant chemotherapy treatment decisions for pre- and postmenopausal women. EndoPredict also provides information about the long-term risk of distant metastasis after 5 years of endocrine therapy which can guide the decision on whether extended endocrine therapy is needed.

EndoPredict gene expression assay uses molecular biology and clinical pathological factors to provide accurate prognostic insights for early-stage breast cancer

EndoPredict breast cancer test is predictive of adjuvant chemotherapy treatment benefit and prognostic of disease outcome

EndoPredict Breast Cancer Prognostic Test gene expression assay gives an individualized risk assessment to guide critical treatment decisions in early-stage breast cancer:

Can adjuvant chemotherapy be avoided?

EndoPredict breast cancer test supports confident decisions about whether adjuvant chemotherapy can be avoided.1 It gives an accurate risk assessment of distant recurrence at 10 years after 5 years of hormone therapy.

What is the absolute benefit of chemotherapy?

EndoPredict analyzes the absolute benefit of chemotherapy on risk of distant breast cancer recurrence within current treatment regimens.2

Can endocrine therapy be avoided after five years?

EndoPredict helps to decide if extended endocrine therapy for breast cancer can be avoided.3 It is the only gene expression assay that provides late distant recurrence risk up to 15 years.

More prognostic power than other breast cancer tests4,5

EndoPredict combines information about tumor size and nodal status with a gene expression signature that includes genes that predict both early and late breast cancer metastasis. This improves the prognostic power of EndoPredict compared with classical prognostic factors and first generation breast cancer tests.4-6

The higher the Likelihood (x2), the greater the prognostic power

The Likelihood (x2) is a statistical tool used to evaluate the accuracy of an algorithm and therefore the prognostic power of a test by comparing predicted outcomes with actual events. Results are independent of test cut-off values.
