Constitution of a Biological Collection to Establish Preclinical Translational Models for the Study of Tumors and Chronic Liver Diseases

What this Trial Is About

Researchers are studying chronic liver diseases and tumors, including non-alcoholic steatohepatitis NASH, non-alcoholic fatty liver disease NAFLD, cirrhosis, and hepatocellular carcinoma HCC. These conditions can be caused by viral infections like hepatitis B, C, and D or lifestyle factors such as overeating and lack of exercise. The goal is to develop better understanding and new treatments by analyzing liver tissues and tumors at the single-cell level to identify therapeutic targets and improve patient outcomes. The study involves creating patient-derived preclinical models, such as spheroid cultures and mouse xenograft models, to test new treatment strategies. Blood samples and tissue biopsies are collected during surgeries, biopsies, or diagnostic tests. Researchers use advanced molecular techniques like single-cell RNA sequencing to examine tumor heterogeneity and the liver environment, aiming to discover new biomarkers and treatment predictors. Participants will undergo procedures as part of their care, including hepato-bilio-pancreatic surgery, biopsies, or locoregional treatments. Blood samples are taken during these procedures to support research. Researchers will monitor surgery outcomes over an average of eight years. By studying patient samples and clinical data, the team aims to improve personalized medicine approaches and identify new preventive and therapeutic targets for chronic liver diseases and liver cancer.
