Can a simple blood test predict cancer treatment success?
NCT ID NCT07060950
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This study will collect blood samples from 620 adults with cancer (including lung cancer) to look for tiny markers released by tumors. Researchers want to see if these markers can help predict how well treatments work or when the cancer might come back. The study does not test a new drug, but aims to improve how we monitor cancer.
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 help develop blood tests to better predict how well cancer treatments work and detect resistance early.
- What could go wrong
- This is an observational study, not a treatment trial. It is still in early stages, and the findings may not lead to immediate clinical use.
