Can a breath test spot lung cancer return?
NCT ID NCT06707519
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study looks at whether DNA from blood, sputum, lung fluid, and breath can help find genetic changes in non-small cell lung cancer. Researchers will collect samples from 210 patients before and after surgery, then follow them for 24 months to check for cancer return. The goal is to see if these sample types are practical and reliable for detecting mutations, not to test a new treatment.
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 show that simple breath or sputum tests help detect lung cancer mutations or recurrence after surgery, potentially reducing the need for invasive biopsies.
- What could go wrong
- This is a small, early feasibility study, not a treatment trial. It only tests whether collecting and analyzing these samples is practical, not whether they improve patient outcomes. Results may not apply to all lung cancer patients.
