The aim of the study is to build up a bio-collection of biological samples from patients with cirrhosis. Further work using this bio-collection will permit to describe the influence of different exposome factors (nutrition, physical activity, socio-demographic conditions, tobacco, alcohol, pollutants) on the occurrence of the main type of liver cancer (called HCC).
Indeed, in the vast majority of cases, HCC develops within cirrhosis, and the factors that precipitate the progression of cirrhotic patients to HCC remain largely unknown.
Presence of metabolic and/or alcoholic steatotic liver disease, as defined by the new nomenclature (MASLD, ALD, or mixed MetALD)
Liver biopsy performed (less than 2 months ago) or planned as part of treatment for diagnosis of cirrhosis ("Control" group without HCC) or diagnosis of HCC on cirrhosis ("Case" group)
Patient affiliated to or benefiting from a social security scheme
Patient having signed an informed consent to participate in the study (bio-collection)
Causes of chronic liver disease other than MASLD, ALD, or MetALD
Decompensation of cirrhosis in the two years prior to inclusion (ascites, hepatic encephalopathy, gastrointestinal variceal hemorrhage, liver failure, hepatorenal syndrome)
For the "Control" group: history of hepatocellular carcinoma
Pregnant, breast-feeding or parturient women
Parallel
Blood, urine and stool biocollection
Other interventionCollection of blood, urine and stool sampling in order to build up a biocollection
Blood sample for biocollection
Blood samples will be collected in order to create a biocollection. Biological parameters will be defined only with future studies (no biological parameter scheduled for this study).
Urinary sample for biocollection
Urinary samples will be collected in order to create a biocollection. Biological parameters will be defined only with future studies (no biological parameter scheduled for this study).
faecal sample for biocollection
Faecal samples will be collected in order to create a biocollection. Biological parameters will be defined only with future studies (no biological parameter scheduled for this study).
