CAR-T cell therapy for colorectal cancer in the liver
This Phase 1 study tests an anti-CEA CAR-T cell treatment for people whose colorectal cancer spread to the liver but has been surgically removed with no visible remaining tumor. It aims to see if the treatment can better prevent the cancer from coming back, especially when early warning tests suggest leftover cancer cells.

Screening for early stomach cancer in Shaanxi
This trial is a community screening program to look for early stomach cancer in adults in Shaanxi. It may help doctors find cancer earlier, when treatment can be more effective.
Xi'an, ShaanxiAges 20 years+ - NCT04037956Recruiting
No-tube surgery versus usual laparoscopy for rectosigmoid cancer
This trial compares two surgical approaches to remove rectosigmoid cancer: a “tubeless” method versus standard laparoscopic surgery. It aims to see which approach works better and is easier or safer for recovery.
Guangzhou, GuangdongAges 18–75 - NCT03825575Recruiting
Nerve stimulation to help control bowel leaks
This study looks at using a small nerve stimulation approach to improve fecal incontinence (bowel leaks). If it works for you, it could help you have more control and fewer accidents.
Hamilton, OntarioAges 6–80 - NCT04613570Recruiting
Follow-up endoscopy plan for early stomach changes
This study looks at how often and how intensely to do follow-up stomach camera exams (endoscopy) with small biopsies for people at risk of stomach cancer. It may help personalize your follow-up schedule based on your specific stomach findings.
PortoAges 45 years+ - NCT04946773Recruiting
Deep liver testing study for cancer and non-cancer liver disease
This study looks closely at how the liver’s immune system and disease processes work in people with liver problems, including some with suspected or confirmed liver/bile duct cancer. You may also be offered a liver needle sample (FNA) if it’s safe for you.
Oxford, OxfordshireAges 18–75 - NCT05335603Recruiting
Study of adults with liver conditions linked to fatty liver
This study looks at adults with different long-term liver conditions that are associated with fatty liver. It helps researchers better understand these diseases and factors linked to them.
HvidovreAges 18 years+ - NCT03200379Recruiting
Taiwan registry for people treated for hepatitis C
This registry is for people in Taiwan who have received direct-acting antiviral (DAA) treatment for hepatitis C. It collects health information to better understand outcomes and care, and you can join if you agree to participate and sign consent.
Kaohsiung CityAges Any age - NCT05323201RecruitingPhase 1/Phase 2
B7H3 CAR-T therapy for advanced liver cancer
This trial tests an immune therapy made from your own blood cells (CAR-T) to treat advanced, unresectable liver cancer. It’s designed for people whose tumor has a specific marker called B7H3 and who meet blood, organ, and safety requirements.
Xuzhou, JiangsuAges 18–70 - NCT04938986Recruiting
Testing a tumor marker to predict colon cancer relapse risk
This study looks at whether a lab test on your tumor can better predict the chance that non-metastatic colon cancer will come back after surgery. Researchers will compare relapse risk using the Immunoscore® test to help guide follow-up and treatment decisions.
MarseilleAges 18–80 - NCT05327478Recruiting
Compare treatments for controlled donation after circulatory death
This trial compares different care approaches for adult donors in a specific type of controlled donation after the heart stops. It aims to find which approach best supports organ/tissue use after donation.
Rotterdam, South HollandAges 50–75 - NCT05323929Recruiting
Checks how scar depth after stomach tumor removal affects healing
This study looks at early stomach cancer treated with ESD, a procedure to remove the tumor through the stomach lining, and how the depth of the scar relates to healing. It may help doctors predict better outcomes and improve the procedure for suitable patients.
Hangzhou, ZhejiangAges 18–75 - NCT05327517Recruiting
Surgery or chemo-radiation for cervical esophagus cancer
This study compares two ways to treat cervical esophagus squamous cell cancer: surgery alone versus chemo-radiation (chemotherapy plus radiation). It may help find the best approach to control the cancer while keeping side effects manageable.
BeijingAges 18–75 - NCT05330910Recruiting
Repair of a stomach valve during sleeve weight-loss surgery
This trial tests whether doing a specific repair near the stomach valve (the gastroesophageal junction) during laparoscopic sleeve gastrectomy can help people with a loose valve. It is aimed at adults who have a particular endoscopy finding (Hill grade III) and choose this weight-loss surgery.
SingaporeAges 21–65 - NCT05342233Recruiting
Compare watchful care versus catheter treatment for a bowel artery tear
This study compares two ways to treat an isolated tear in the superior mesenteric artery (a blood vessel that supplies the intestines): conservative (watchful care) versus endovascular (catheter-based) treatment. It may help doctors figure out which approach works best for people whose condition is confirmed on a CT angiogram and who are stable enough for either plan.
Changsha, HunanAges 18 years+ - NCT03972956Recruiting
Collecting samples during cancer or surgery visits
This trial looks at collecting (taking) medical samples from people who need surgery for colorectal cancer, stomach (gastric) cancer, or a non-cancer condition. It may help researchers better understand these diseases and improve how treatment is planned.
Wuhan, HubeiAges 18–80 - NCT05347524Recruiting
Blood test study to detect stomach cancer spread in the belly
This study checks whether a blood liquid biopsy test can detect when stomach cancer has spread to the lining of the abdomen (peritoneal metastasis). It compares people with confirmed belly spread to people whose belly lining tests were negative, using blood samples before/around treatment decisions.
Shanghai, Shanghai MunicipalityAges 18–74 - NCT05361603Recruiting
Screening for hepatitis B, C, and HIV at the same time

If you are eligible, treatment is given around the time of planned surgery to remove the tumor and lymph nodes.
Zhengzhou, HenanAges 18–80 - NCT03746210Recruiting
