BesançonAges 18 years+ - NCT01416714Recruiting
Tissue sample collection during cancer surgery or biopsy
This study is collecting tissue samples from people with certain cancers while they have surgery or a biopsy. It may help researchers learn more about these cancers and improve future diagnosis and treatment.
Chicago, IllinoisAges Any age - NCT02754115Recruiting
Audit of surgery with heated chemo for belly tumors
This study is an audit (a review of care) of patients who undergo cytoreductive surgery plus heated chemotherapy placed in the abdomen. It helps doctors understand how this treatment is done and what outcomes and safety it has.
Mumbai, MaharashtraAges 18–70 - NCT02292641Recruiting
MRI study for repeat pelvic colorectal cancer
This study uses a special MRI to help understand and stage colorectal cancer that has come back in the pelvis. The goal is to improve how doctors make treatment decisions after previous surgery.
OsloAges 16 years+ - NCT07432399RecruitingPhase 2
Lidocaine or dexamethasone before colon cancer surgery
This study tests whether giving lidocaine or a high-dose steroid before colon cancer surgery can improve immune function and recovery. The goal is to find a simple, safe way to help your body respond better during surgery.
LjubljanaAges 18 years+ - NCT05501353Recruiting
Study tumor biomarkers in recurrent metastatic colon cancer
This study looks for blood/tumor signals (“biomarkers”) that may help predict outcomes in people whose colorectal cancer returns and spreads after surgery. It mainly helps researchers understand who may do better or worse, which can guide future care.
Hangzhou, ZhejiangAges 18–99 - NCT01915225Recruiting
Collecting solid tumor samples during cancer biopsy or surgery
This trial collects tissue (samples) from people who are already scheduled for biopsy or surgery for certain solid cancers. It aims to improve future testing and research while checking that taking the sample is safe and doesn’t add extra risk.
Bethesda, MarylandAges 2 years+ - NCT06540027Enrolling by invitation
Minimally invasive surgery for rectal cancer inflammation
This study looks at how different types of surgery (open, laparoscopic, or robotic) affect inflammation throughout the body in people with rectal cancer. It may help doctors understand which approach is gentler on your immune system.
IstanbulAges Any age - NCT05642819Recruiting
MRI before and after surgery for abdominal cancers
This study uses extra detailed MRI scans before and/or around planned abdominal surgery to help researchers understand changes in the body. It includes people having surgery for certain cancers and some people having surgery for non-cancer (benign) conditions.
EdinburghAges 18 years+ - NCT06477991Recruiting
No surgery after immunotherapy for MSI-H colorectal cancer
This trial is studying whether some people with a specific type of advanced colorectal cancer (MSI-H/dMMR) might be able to skip surgery after immunotherapy. Doctors will use a blood test (MRD monitoring) to track the cancer, and then decide whether to keep an eye on it or operate.
Kunming, YunnanAges 18–75 - NCT06934018Recruiting
Surgical margin width for liver-only colorectal cancer spread
This trial tests whether a wider surgical margin (at least 7mm) during liver surgery improves survival and reduces cancer return in patients whose colorectal cancer has spread to the liver but not elsewhere. It aims to remove all visible liver tumors with a safe margin.
Shanghai, Shanghai MunicipalityAges 18 years+ - NCT07542171Recruiting
Outcomes after incomplete early colon cancer removal
This study follows patients who had early colon cancer removed by endoscopy (a camera procedure) but the removal was incomplete. Researchers will track what happens when patients either have surgery afterward or are closely watched instead, to understand the best next steps.
Guangzhou, GuangdongAges 18–75 - NCT06197425RecruitingPhase 3
Extra chemotherapy after surgery for colorectal cancer with positive ctDNA
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.
DijonAges 18–80 - NCT07058012RecruitingPhase 2
Testing immunotherapy for ctDNA-positive colorectal cancer after treatment
This trial is for people with colorectal cancer whose ctDNA blood test is still positive after surgery and chemotherapy. It tests two immunotherapy drugs (cemiplimab alone or with fianlimab) to see if they can eliminate the remaining cancer cells and prevent the cancer from coming back.
Gainesville, FloridaAges 18 years+ - NCT02222844Recruiting
MRI checks for treatment planning in sigmoid colon cancer
This study uses MRI scans to better plan “curative” treatment (aimed at cure) for sigmoid colon cancer before surgery. It is for people who may still be deciding on the radical (major, curative) treatment plan and who can safely have an MRI.
Huntingdon, CambridgeshireAges 16 years+ - NCT06583564Enrolling by invitation
ICG dye during surgery for stage III colorectal cancer
This study tests whether using a special dye during surgery helps people with stage III colorectal cancer stay cancer-free longer. The dye, called indocyanine green (ICG), makes tumors and lymph nodes glow under a special camera, helping surgeons remove them more precisely.
Changning, Shanghai MunicipalityAges 18 years+ - NCT00001823Recruiting
Surgery Branch Screening for Cancer Treatment Studies
This is a screening evaluation to see if you might be eligible for cancer treatment research studies at the National Cancer Institute's Surgery Branch. Doctors will review your medical history, imaging, and test results to determine which clinical trials might be right for you.
Bethesda, MarylandAges 18 years+ - NCT06449937Recruiting
Local liver treatment for colorectal cancer that has spread
This trial tests whether treating liver tumors with surgery or ablation can help people whose colorectal cancer has spread to the liver and other organs. It may be an option if you've had only 1 or 2 types of chemotherapy and your non-liver metastases are stable.
Chuzhou, AnhuiAges 18–80 - NCT06307548RecruitingPhase 1/Phase 2
Image-guided surgery and light therapy for colorectal cancer
This trial tests a special dye that helps surgeons see tumors more clearly during surgery, followed by a light therapy to destroy any remaining cancer cells. It is for people with advanced or returning colorectal cancer who are already scheduled for surgery.
Buffalo, New YorkAges 18 years+ - NCT05861505RecruitingPhase 3
Treatment for new liver spread from colon cancer recurrence
This Phase 3 trial studies a treatment approach for people whose colorectal cancer has come back in the liver within 12 months and can be treated with local procedures. It aims to see whether the study treatment can improve outcomes compared with standard care for people with a limited number of liver tumors.
