Blood test may predict melanoma return
NCT ID NCT07422805
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study is looking at whether a blood test that detects circulating tumor DNA (ctDNA) can help predict if melanoma will come back or spread. Researchers are following 176 adult melanoma patients and comparing ctDNA levels with standard clinical and lab results. The goal is to see if this simple blood test could be a useful tool for monitoring the disease.
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 lead to a simple blood test to monitor melanoma patients for signs of cancer returning or spreading.
- What could go wrong
- This is an early-phase observational study, not a treatment trial. The blood test may not prove reliable enough to replace standard monitoring methods.
