Blood test may catch melanoma recurrence months before scans
NCT ID NCT06246227
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at whether a blood test that detects tumor DNA can find melanoma recurrence earlier than standard methods. Researchers will follow 467 high-risk patients who have had primary melanoma removed. If the test works, it could lead to faster treatment and better outcomes.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- circulating tumor DNA (ctDNA) blood test
- What this could lead to
- If successful, this blood test could help catch melanoma recurrence earlier than current scans or exams, potentially improving treatment timing and outcomes.
- What could go wrong
- This is an observational study, not a treatment trial. The test may not detect all recurrences, and earlier detection does not guarantee better survival. Results need validation in larger trials.
