Study mapping sentinel lymph nodes to guide colon cancer surgery
This trial looks at a minimally invasive surgery approach for people with colon adenocarcinoma that has not spread to lymph nodes or other organs. The team will use special mapping tests on the sentinel lymph node to better understand the cancer spread and help guide treatment decisions.
GhentAges 18 years+ - NCT05773144Recruiting
Exercise program during chemotherapy for colon cancer recovery
This trial tests an aerobic exercise plan during chemotherapy for people with stage II or III colon cancer. It compares different exercise approaches to see if exercise can be done safely and may improve how you tolerate treatment and recovery.
Oakland, CaliforniaAges 18 years+ - NCT07230639RecruitingPhase 2
Shorter radiation with chemo and immunotherapy for high-risk colon cancer
This trial tests a shorter course of radiation combined with chemotherapy and an immunotherapy drug (PD-1 inhibitor) for people with a specific type of high-risk colon cancer that has not spread. The goal is to see if this approach can shrink the tumor before surgery and improve outcomes.
Guangzhou, GuangdongAges 18–75 - NCT05723250Recruiting
Rural early cancer care coaching and education program
This study tests an educational “care coordination” program to help people living in rural Vermont manage care during the early stages of breast, lung, or colon cancer treatment. It may help you feel more supported and organized while starting or preparing for chemotherapy.
Burlington, VermontAges 18 years+ - NCT06886282Recruiting
How colon cancer and kidney disease are linked: a imaging and gene study
This trial uses advanced imaging and genetic tests to understand how colon cancer and chronic kidney disease may be connected. It may help decide the best treatment for people with both conditions.
NaplesAges 18 years+ - NCT04920032RecruitingPhase 1
Blood test–guided extra treatment for colon cancer recurrence risk
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.
Orange, CaliforniaAges 18 years+ - NCT06244537Recruiting
MR-Linac radiation for advanced colon cancer
This trial tests a new radiation machine called MR-Linac for people with advanced colon cancer that cannot be removed by surgery. The goal is to see if it is safe and works well.
Chengdu, SichuanAges 18 years+ - NCT05672108RecruitingPhase 2
Chemo delivered into lung tumors using a catheter
This trial studies a treatment that delivers chemotherapy directly to lung tumors by placing a catheter into lung blood vessels. It may help people with lung cancer or lung metastases that are growing despite standard treatment, or who cannot tolerate it.
Duarte, CaliforniaAges 18 years+ - NCT05789433Recruiting
Aerobic exercise study after colon or rectal cancer surgery
This trial studies whether a supervised aerobic exercise program helps muscles “remodel” (change/strengthen) after colon or rectal cancer treatment. It may help people improve physical function during recovery, but you can only join if it’s safe for you and you can follow the study plan.
Orlando, FloridaAges 18 years+ - NCT05236972RecruitingPhase 3
PD-1 antibody after colon cancer surgery for dMMR stage III
This phase 3 trial studies a PD-1 antibody medicine given after surgery to help prevent stage III colon cancer from coming back. It is specifically for people whose tumor is mismatch repair–defective (dMMR) or MSI-H, which may make the cancer more responsive to immune-based treatment.
GuangzhouAges 18–75 - NCT06121089Recruiting
Surgery for early-stage cecal cancer
