NCT ID NCT03503799
First seen Apr 15, 2026 · Last updated Apr 30, 2026 · Updated 2 times
Summary
This study follows over 1,100 women with early-stage, hormone-sensitive breast cancer to see if those with a low-risk result on the EndoPredict® gene test can safely avoid chemotherapy and use only hormone therapy. Researchers are tracking whether these patients remain cancer-free for at least 10 years. The goal is to confirm that the test accurately identifies women who do not need chemo.
