Blood tests and surveys may predict cancer treatment success
NCT ID NCT04776837
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study followed 159 people with metastatic colorectal, pancreatic, biliary, or esophageal cancers who were starting a new line of therapy. Researchers collected blood samples (tumor markers and liquid biopsies) and patient-reported quality-of-life data to see if these could predict how well the treatment worked at the first scan. The goal was to find better ways to track disease progression and response without relying solely on imaging.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- What this could lead to
- If successful, this could help doctors better predict how well a cancer treatment is working early on, using simple blood tests and patient surveys.
- What could go wrong
- This is an observational study, not a treatment trial. It may not lead to any immediate changes in care, and the results might not apply to all patients.
