Blood test may predict who needs less immunotherapy after lung cancer surgery

NCT ID NCT06902272

First seen Jul 22, 2026 · Last updated Jul 23, 2026 · Updated 1 time

Summary

This study is testing whether a blood test that looks for bits of tumor DNA (called ctDNA) can predict how well people with early-stage lung cancer respond to treatment. Researchers want to see if the test can identify patients who have no cancer left after chemotherapy and immunotherapy, so they might safely receive less immunotherapy after surgery. The trial involves about 30 adults with stage IB to IIIB non-small cell lung cancer who are scheduled for surgery.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance
a blood test that measures circulating tumor DNA (ctDNA) to guide treatment decisions, along with the immunotherapy drug pembrolizumab
What this could lead to
If successful, this approach could allow some patients to receive less immunotherapy after surgery, reducing side effects while still preventing cancer from returning.
What could go wrong
This is a small, early-phase study, so results may not apply to all patients. The ctDNA test may not reliably predict outcomes, and reducing immunotherapy could increase the risk of cancer recurrence.
