Using blood DNA tests to guide colon cancer treatment after surgery
Treatments studied
Part of Cancer clinical trials.
This trial tests whether a blood test that looks at cancer DNA can help decide whether you need “adjuvant” (extra) chemotherapy after colon cancer surgery. It may help some patients avoid unnecessary chemotherapy while still keeping the cancer from coming back.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 18 to 75 years old
- You had curative surgery for stage II colon or “high rectal” cancer, with no leftover cancer seen after surgery
- At least 12 lymph nodes were checked, and a recent scan showed no spread to other organs
- Your doctors discussed your case and decided not to give chemotherapy after surgery
- Your health is good enough for treatment (for example, blood counts and organ tests meet study limits)
- You have not had prior chemotherapy for colon/rectal cancer and no prior radiation to the belly or pelvis for this cancer

Other trials that look related to this one.
This trial tests whether giving more chemotherapy can help people who still have cancer DNA in their blood after surgery and standard chemotherapy for colorectal cancer. The goal is to prevent the cancer from coming back.
This study tests whether giving additional (adjuvant) chemotherapy based on a special blood test—circulating tumor DNA (ctDNA)—can lower the risk of colon cancer coming back. It targets people with stage II–III colon cancer whose blood test is positive for minimal residual disease (MRD) after completing standard chemo.
This trial checks whether a special blood test (ctDNA methylation) can help decide the best chemotherapy after surgery for people at higher risk of colon cancer coming back. It may help spare some patients unnecessary treatment while aiming to improve outcomes for those likely to relapse.
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 studies how to find tiny hidden cancer cells after stage III colon cancer surgery using a blood test. If the blood test shows tumor DNA, you may get additional treatment to lower the chance of cancer coming back.
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.
