Blood test could predict cancer return after surgery

NCT ID NCT03637686

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

Summary

This study looks at whether a simple blood test can find tiny bits of cancer DNA left in the body after surgery for colorectal cancer. The goal is to identify patients at high risk of the cancer coming back, so doctors can adjust follow-up care. Over 3,000 people with stage I-III colorectal cancer are taking part. The test is not a treatment itself, but a way to better understand and monitor the disease.
