Adjuvant colon chemotherapy guided by tumor DNA results
Treatments studied
Part of Cancer, Digestive system clinical trials.
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.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are able to do normal activities at the study level (ECOG 0 or 1).
- Your colon cancer is stage IIB, IIC, or III adenocarcinoma and was fully removed with no visible spread (R0 surgery).
- Your scans from within 45 days before starting shows no metastatic (spread) cancer.
- Your surgery must be within 7 to 60 days before you start the study.
- Your tumor must be microsatellite stable (not MSI-H) or have intact mismatch repair proteins (not dMMR).
- After surgery, you must be able to provide required tumor tissue and blood for the ctDNA blood test (Signatera), with blood ideally at least 14 days after surgery.

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 Phase 1 study uses a blood test called ctDNA to decide whether and how to adjust treatment in people with colon cancer who still have a small amount of disease left after surgery. If your blood test remains positive, the trial aims to reduce recurrence risk by guiding treatment changes.
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 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 uses two blood tests (Signatera and Haystack) to look for tiny bits of cancer DNA after surgery, to find out if the cancer comes back as early as possible. People with stage II, III, or IV colorectal cancer who have had or will have surgery to remove their tumor may join.
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.
