Blood test could guide who needs extra cancer therapy after lung surgery

NCT ID NCT06426511

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This study tests whether a blood test that detects tiny bits of tumor DNA (ctDNA) can help doctors decide who needs additional immunotherapy (toripalimab) after lung cancer surgery. About 80 people with stage IB-IIIA non-small-cell lung cancer will be enrolled. The goal is to see if this personalized approach works as well as giving everyone the same long course of treatment, potentially sparing some patients from unnecessary therapy.

What this could mean

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

Active substance

Toripalimab (a drug that helps the immune system fight cancer)

What this could lead to

If successful, this could mean that some people with lung cancer can receive less treatment after surgery, reducing side effects while still preventing the cancer from coming back.

What could go wrong

This is a small, early-phase trial (Phase 2) with only 80 participants, so results may not apply to everyone. The ctDNA-guided approach might not be as effective as standard treatment in preventing cancer recurrence.
