High EPclin Score Equals Chemo Benefit in ER+/HER2– Breast Cancer

Key clinical point: The EPclin assay is predictive of absolute chemotherapy benefit in ER+/HER2– breast cancer.

Major finding: The absolute 10-year benefit for patients with high scores would be 5.3 to 7.3%.

Study details: Description of a mathematical model to predict absolute chemotherapy benefit in women with estrogen receptor–positive, HER2-negative breast cancer.
