Blood test to spot DNA changes after early colon cancer surgery
Part of Cancer, Digestive system clinical trials.
This study checks a “cell-free tumor DNA” blood test to see if cancer mutations can predict relapse after surgery for early colorectal cancer. If results look risky, they may help guide closer follow-up and future treatment decisions.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You’re 18 or older and can sign informed consent
- You have early colorectal cancer (colon or rectal) with curative-intent surgery planned, with no confirmed spread to distant organs on scans
- For Parts B/C: You must be able to follow the study’s clinic and blood-test follow-up schedule
- For Part C specifically: After surgery, your doctors must plan you to receive adjuvant (after-surgery) chemotherapy

This study looks at a blood “DNA” test to see if it can help monitor colorectal cancer after surgery. It may benefit you by improving how doctors track cancer during routine follow-up visits.
This study uses a simple blood test to detect cancer DNA after surgery for early-stage colon cancer. The goal is to help doctors decide whether chemotherapy is truly needed based on the blood test results, rather than giving it to everyone.
This study tests if a simple blood test can detect early signs of colorectal cancer coming back after surgery to remove cancer spread in the abdomen. It may help patients avoid unnecessary treatments and catch recurrence sooner.
This study tests whether a special blood test (looking for cancer DNA) can help doctors decide if you need chemotherapy after colorectal cancer surgery. The goal is to avoid unnecessary chemotherapy while making sure patients who need it get treated.
This trial checks a stool test called FIT-DNA after colorectal (colon) cancer surgery. It aims to see whether this test can help doctors monitor for recurrence during follow-up and decide how closely to watch.
This trial uses a blood test (liquid biopsy) to look for tiny bits of cancer DNA remaining after surgery. It aims to see if this test can help guide follow-up and treatment decisions for people with colorectal cancer.
