Blood test could spot lung cancer return risk after surgery
NCT ID NCT04966663
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at whether a simple blood test that finds cancer DNA can help doctors decide who needs extra treatment after lung cancer surgery. About 66 people who had their lung cancer removed will either get chemo-immunotherapy or just be watched. The goal is to see if the blood test can identify those at high risk of cancer coming back and if the extra treatment helps prevent that.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
Nivolumab, Pemetrexed, Gemcitabine, Cisplatin, Carboplatin
What this could lead to
If successful, this could show that using a blood test to detect leftover cancer DNA helps doctors decide who needs extra treatment after surgery, potentially lowering the chance of cancer returning.
What could go wrong
This is a small Phase 2 trial, so results are early and may not apply to everyone. The added chemo-immunotherapy can cause significant side effects, and the blood test may not reliably predict recurrence in all patients.
