Summary

This study tested a blood test that looks for tiny bits of cancer DNA left after surgery in people with stage II or III colorectal cancer. The goal was to see if the test could find patients at high risk of the cancer coming back, so they could get the right extra treatment. 175 adults who had surgery took part, and the test was checked against standard scans and follow-up.
