Blood Test to Guide Chemotherapy After Colon Cancer Surgery
Treatments studied
Part of Cancer, Digestive system clinical trials.
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.
Summary written for real people, not researchers, by Clin2.

- Age 18 or older
- Surgery for high-risk stage II colorectal (colon) cancer within the past month
- Cancer DNA detected in blood test at 1 month after surgery
- Overall health good enough to tolerate treatment (ECOG score 0–2)
- Expected to live at least 12 months
- No prior chemotherapy or radiation before surgery

This study helps doctors decide whether you need chemotherapy after colon cancer surgery by checking for cancer DNA in your blood. The goal is to give chemotherapy only to patients who truly need it, based on what the blood test shows.
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 tests whether a special blood test that detects cancer DNA can help doctors decide if you need additional chemotherapy after colorectal cancer surgery. The goal is to personalize treatment based on your individual risk rather than giving chemotherapy to everyone.
This study uses a blood test to check for tumor DNA after surgery, which may help doctors decide if you need additional chemotherapy. It is for people with stage 3 colorectal cancer that is removed by surgery.
This trial checks whether giving chemotherapy after surgery only for people whose blood test (ctDNA) shows no remaining cancer can help prevent the cancer from coming back. It is for people with colon cancer that has spread to the liver who had the tumor fully removed.
This study uses a simple blood test (liquid biopsy) to look for tiny bits of cancer DNA after surgery for colorectal cancer that spread to the liver. It aims to see if this test can find cancer earlier than standard scans, which may help guide future treatment decisions.
