China liver cancer patient registry study
This study is creating a database of people with liver cancer (including hepatocellular carcinoma and other types). It aims to collect health information and samples over time to better understand the disease and improve future care. If you join, you will be asked to provide blood and leftover tissue from surgery or biopsy, and to follow up with the research team.

Blood test to predict liver cancer in cirrhosis patients
This trial tests if a simple blood test can help predict who with cirrhosis might develop liver cancer, so doctors can monitor and treat those patients earlier.
Vandœuvre-lès-NancyAges 18 years+ - NCT06778382RecruitingPhase 2
Delaying treatment after destroying lung spots from colorectal cancer
This trial tests if it's safe to wait before starting full-body therapy after treating a small number of lung tumors (5 or fewer) in people whose colorectal cancer had been gone for at least 6 months. You would first get local treatments like surgery or radiation to destroy the lung spots, then delay additional cancer drugs to see how you do.
Jinan, ShandongAges 18–75 - NCT06778954Recruiting
Pain control gel after stomach cancer surgery
This trial tests a gel (ropivacaine in a special polymer) applied during stomach cancer surgery to reduce pain after the operation. The goal is to help patients recover with less pain and fewer side effects from painkillers.
SeoulAges 20 years+ - NCT06779058Recruiting
Liver stiffness testing for hepatitis B patients
This trial uses MR elastography (a special MRI) to measure liver stiffness and check for fibrosis (scarring) without a needle biopsy. It may help guide treatment for chronic hepatitis B.
Shenyang, LiaoningAges 18–80 - NCT06779864Recruiting
Hepatitis B virus genetics and drug resistance study
This study looks at how hepatitis B virus changes in your body, including mutations and drug resistance, using your blood or liver tissue samples. Understanding these changes could help improve treatment for hepatitis B.
Beijing, Beijing MunicipalityAges 18 years+ - NCT06780423Recruiting
Muscle changes in colorectal cancer cachexia
This study compares muscle changes in people with colorectal cancer who have experienced weight loss (cachexia), those with colorectal cancer without weight loss, and healthy volunteers. Participants will have their trunk and leg muscles examined to understand how cachexia affects the body.
Diepenbeek, LimburgAges 18 years+ - NCT06780683Recruiting
Testing upadacitinib for inflammatory bowel disease
This study tests a medication called upadacitinib for people with inflammatory bowel disease (ulcerative colitis or Crohn's). The goal is to see how well it works and if it's safe.
Guangzhou, GuangdongAges Any age - NCT06780787RecruitingPhase 2
Study of chemo plus immunotherapy for localized rectal cancer before surgery
This trial tests a combination of chemotherapy (FOLFOX) and two immunotherapies (botensilimab and balstilimab) before surgery for patients with localized rectal cancer. It aims to see if adding immunotherapy helps shrink the tumor and improve outcomes.
Duarte, CaliforniaAges 18 years+ - NCT06781242Recruiting
Genes and symptoms in inherited bile flow problems
This study looks at how genes affect bile flow problems in the liver. If you have a rare genetic condition like PFIC, researchers want to understand your specific type better by comparing your genes to your symptoms.
Bologna, BolognaAges 18 years+ - NCT06781827Recruiting
Probiotics for newly diagnosed IBD
This study tests whether taking probiotics can help prevent or treat inflammatory bowel disease (IBD) in people recently diagnosed. It aims to see if friendly bacteria can calm gut inflammation and improve symptoms.
Suqian, JiangsuAges 18 years+ - NCT06782412RecruitingPhase 2/Phase 3
New imaging test for different cancers using FAPI-PET
This trial is testing a new imaging method called FAPI-PET to see if it can help find and understand tumors better than standard scans. It is for people with newly diagnosed stomach/esophageal cancer, pancreatic cancer, or those with unclear symptoms or scan results.
EdegemAges 18 years+ - NCT06782555RecruitingPhase 1/Phase 2
Study of experimental drug combo for advanced cancers
This trial tests a new combination of three drugs—evofosfamide, zalifrelimab, and balstilimab—in people with advanced prostate, pancreatic, or certain head and neck cancers that have stopped responding to standard treatments.
Houston, TexasAges 18 years+ - NCT06782932RecruitingPhase 1/Phase 2
Vaccine and Immunotherapy for Removable Pancreatic Cancer
This trial tests two different vaccines (GVAX and a mKRAS vaccine) given before and after surgery for pancreatic cancer. Both vaccines are combined with immunotherapy drugs to help your immune system fight the cancer. The goal is to see which vaccine works better and is safe for patients whose tumors can be removed.
Baltimore, MarylandAges 18 years+ - NCT06783244Recruiting
Low vs standard belly pressure for robot colorectal cancer surgery
This trial is testing whether using lower air pressure inside the belly during robot-assisted colorectal cancer surgery helps patients recover better compared to the standard pressure. It aims to find a gentler approach that might reduce pain and improve recovery.
Copenhagen NVAges 18 years+ - NCT06783491RecruitingPhase 3
Chemotherapy with or without heated chemo for advanced colon cancer
This trial tests if adding heated chemotherapy directly into the abdomen during surgery improves outcomes for people with advanced colon cancer that hasn't spread to other organs. It compares standard chemotherapy before surgery alone versus chemotherapy before surgery plus heated chemo during surgery.
Córdoba, CórdobaAges 18–75 - NCT06783569RecruitingPhase 1
First-in-human study for advanced solid tumors
