NCT ID NCT06654622
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This completed study tested a blood test that looks for tiny cancer leftovers after surgery in 175 people with stage II or III colorectal cancer. The goal was to see if the test could identify who really needs chemotherapy. If it works, it could help personalize treatment and avoid chemo for those who don't need it.
