Scientists hunt for clues in breast cancer tissue to predict relapse
NCT ID NCT02050750
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study collects and stores breast cancer tissue from 600 people who took part in the TAILORx trial. Researchers will analyze the samples to find biological markers that can predict if the cancer will come back or resist hormone therapy and chemotherapy. No new treatments are given; the goal is to better understand the disease.
