Blood test may replace scans for some colorectal cancer patients on immunotherapy
NCT ID NCT06098560
First seen Jun 25, 2026 · Last updated Jul 01, 2026 · Updated 3 times
Summary
This study is looking at whether a simple blood test that tracks tumor DNA (ctDNA) can better predict how well immunotherapy is working in people with advanced colorectal cancer. Currently, doctors rely on imaging scans, which can miss cases where the cancer is actually gone. The study will follow 60 patients to see if changes in ctDNA levels match with complete responses after surgery or over time.
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 lead to a simple blood test to monitor immunotherapy effectiveness in colorectal cancer, helping doctors decide on treatment without relying solely on scans.
What could go wrong
This is an observational study, not a treatment trial. It is small (60 participants) and early-stage, so results may not apply to all patients or change practice immediately.
