Check colorectal cancer blood tests after curative treatment
Part of Cancer, Digestive system clinical trials.
This study measures “minimal residual disease,” meaning tiny amounts of cancer that may remain after surgery, using blood samples. It may help doctors better detect who is at higher risk of cancer coming back and guide follow-up care.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are at least 18 years old.
- You have confirmed colorectal adenocarcinoma (a specific type of colon/rectal cancer).
- You’re planning curative-intent treatment, or you’ve had surgery to remove the tumor completely and are in the first 3 months after it (and before starting planned chemo, if applicable).
- You can understand the study and sign informed consent.
- You agree to follow the usual cancer follow-up schedule after treatment.
- You’re willing to give blood samples for research testing.

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.
This study watches for signs of leftover cancer after surgery using a blood test (MRD). It is for people with early-stage colon cancer who have not yet had any treatment other than surgery.
This study tests whether a simple blood test can track how well your colorectal cancer is responding to first-line chemotherapy. By monitoring cancer markers in your blood, doctors may be able to detect treatment changes earlier than traditional imaging.
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 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 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.
