Blood test may spot cancer return months before scans
NCT ID NCT07426250
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at whether a blood test that detects tumor DNA (ctDNA) can help predict cancer recurrence in 500 patients with oligometastatic cancer (cancer that has spread to only a few spots). Participants will give blood samples before and after local treatment (like surgery or radiation). Researchers will track whether ctDNA levels relate to cancer coming back or survival. The goal is to see if this test could guide future treatment decisions.
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 study could show that a simple blood test (ctDNA) helps doctors detect cancer return earlier and personalize follow-up care for patients with limited metastases.
- What could go wrong
- This is an observational study, not a treatment trial. It will not test a new therapy, and results may not change current practice. ctDNA detection rates vary by cancer type, so findings may not apply to all patients.
