First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This completed study looked at records from over 20,000 women with metastatic breast cancer in France. Researchers wanted to see if earlier measures of treatment success, like progression-free survival, could reliably predict overall survival. By comparing real-world data to clinical trial results, they hope to find faster ways to evaluate new treatments.
