EndoPredict helps you detect risk of recurrence for ER positive/HER2 negative early-stage breast cancer

Gene expression tests are guiding critical treatment decisions in early‑stage breast cancer. Using genomic testing for breast cancer recurrence, you can avoid under or over treatment and the life-changing impact these choices can have on a woman’s life – now and in years to come.

EndoPredict Breast Cancer Prognostic Test is the most accurate gene expression test for early-stage breast cancer recurrence to help you make treatment decisions for your eligible ER positive/HER2 negative primary invasive breast cancer patients.2,3

Confident decisions across all patient groups

Chemotherapy in premenopausal breast cancer

EndoPredict Breast Cancer Prognostic Test is the only second generation breast cancer recurrence gene expression test validated for premenopausal AND postmenopausal women.3-12

Node positive breast cancer and chemotherapy

EndoPredict Breast Cancer Prognostic Test is the only second generation test with level of evidence 1A9,10 for node positive breast cancer. The test is validated to accurately identify node positive breast cancer patients with true low-risk of cancer recurrence, allowing more of your patients to safely avoid adjuvant chemotherapy.3-12

For node negative patients, EndoPredict correctly identifies a large group at low-risk BUT also classifies high-risk patients who can benefit from chemotherapy.3,6
