Testing blood tumor DNA treatment after stage III colon surgery
Treatments studied
Part of Cancer, Digestive system clinical trials.
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.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You had stage III colon cancer (colon adenocarcinoma) removed completely by surgery.
- The tumor was fully removed and was only in the colon (not involving the rectum).
- You finished standard chemotherapy after surgery and haven’t had any chemo before surgery.
- You are age 18 or older, in generally good condition, and expected to live more than 3 months.
- Your blood counts and organ tests (liver/kidneys) must be within acceptable ranges.
- You must be willing to sign consent and follow study visits; you’ll also need required tumor and blood test results.

Other trials that look related to this one.
This trial tests whether treatment for colon cancer after surgery can be guided by a blood test that looks for leftover cancer signals (ctDNA). It may help some people choose stronger or different chemo based on whether ctDNA is found after surgery.
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 tests whether checking for cancer DNA in your blood (ctDNA) can help doctors decide if you need extra chemotherapy after surgery for stage III colon cancer. It aims to personalize treatment and avoid unnecessary chemo.
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.
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 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.
