Blood test for cancer DNA after liver surgery in colorectal cancer
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.
MontpellierAges 18 years+ - NCT06287749Recruiting
Liquid biopsy for monitoring pancreatic cancer after surgery
This trial is testing a blood test (liquid biopsy) to look for tiny traces of cancer DNA after surgery for pancreatic cancer. It may help doctors understand if the cancer is likely to come back.
Montpellier, HéraultAges 18 years+ - NCT07052578Recruiting
Aggressive prostate cancer study with HRR blood test
This study looks at men with aggressive, high-volume metastatic prostate cancer that is still sensitive to hormone therapy. It will analyze a blood test for HRR gene mutations (like BRCA) to help understand treatment patterns.
ArkhangelskAges 18 years+ - NCT06382103Recruiting
Liver cancer study after surgery or pre-surgery therapy
This study looks at genetic markers in the blood of people with liver cancer who are having surgery, either right away or after some treatment first. It aims to find out why some patients do better, which could help personalize care.
ShanghaiAges Any age - NCT06391892RecruitingPhase 3
Liquid biopsy guided treatment for early pancreatic cancer
This trial uses a liquid biopsy (a simple blood test that looks for cancer DNA) to decide whether you should have chemotherapy before surgery or go straight to surgery. It is for people with pancreatic cancer that has not spread beyond the pancreas.
Linz, Upper AustriaAges 18–99 - NCT06401421Recruiting
Blood test for tumor DNA after breast cancer chemo
This study tests a new blood test to see if it can find tiny bits of tumor DNA after chemotherapy. If you have a larger or higher-risk breast cancer and are getting chemotherapy before surgery, you may join. The test could help doctors know if your cancer is gone or if more treatment is needed.
Anchorage, AlaskaAges 18 years+ - NCT06420427Recruiting
Blood test to predict cervical cancer return after surgery
This trial uses a simple blood test to look for cancer DNA (ctDNA) and HPV DNA after cervical cancer surgery. The goal is to detect any return of the cancer early, so you and your doctor can act quickly.
Guangzhou, GuangdongAges 18 years+ - NCT06426511RecruitingPhase 2
Testing toripalimab after lung cancer surgery using ctDNA
This study tests whether a drug called toripalimab, given after lung cancer surgery, can help keep the cancer from coming back in people with early-stage non-small cell lung cancer. It uses a blood test (ctDNA) to look for leftover cancer cells and decide who might benefit most.
Guangzhou, GuangdongAges 18–75 - NCT06434896Recruiting
Blood test to guide chemotherapy in stage II colon cancer
This trial is for people with stage II colon cancer who are not currently getting chemotherapy. It uses a blood test to look for tumor DNA, so doctors can decide if chemotherapy might help prevent the cancer from coming back.
's-HertogenboschAges 18 years+ - NCT06479070Recruiting
Using ctDNA to guide radiotherapy for head and neck cancer
This study looks at whether measuring a DNA fragment in the blood (called ctDNA) can help predict how well radiotherapy works for head and neck cancer. It may help doctors better tailor treatment for patients with stage III or IV disease.

TaipeiAges 18 years+ - NCT06561178Recruiting
Blood Test to Monitor Esophageal Cancer After Surgery
This trial looks at whether a personalized blood test can detect cancer returning after surgery for esophageal cancer. It tests people who had chemoradiotherapy before surgery and still had some cancer remaining in the removed tissue. The goal is to use the blood test to catch any remaining or returning cancer early.

Common questions
- Are there clinical trials for ctdna?
- Yes. Clin2 currently lists 187 recruiting ctdna studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a ctdna trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a ctdna trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
