The process of liver cancer transformation is complex, so it is particularly important to explore the relationship between various liver diseases on its clinical pathway. Therefore, the investigators carried out this study to explore the changes of plasma and urine metabolites under different liver disease conditions during the development of liver cancer.~(1) Retrospective cohort: 600 patients were recruited, including 120 patients with hepatitis, 120 patients with cirrhosis, 120 patients with fatty liver, 120 patients with liver cancer, and 120 healthy people.,(2) Prospective cohort: 1400 patients were recruited, including 280 hepatitis patients, 280 cirrhosis patients, 280 fatty liver patients, 280 liver cancer patients, and 280 healthy people. During the course of the study, the subjects will not be given or provided with any randomized or any treatment driven by the study protocol. If it is clinically applicable, the treatment physician shall make the treatment decision and choose the treatment plan at his discretion.
The incidence of liver cancer in China shows a clear clinical path of hepatitis/fatty liver liver cirrhosis liver cancer. The dynamic changes of the internal environment on this pathway are important clues for early detection, diagnosis and even cure of liver cancer. The investigators carried out this study to investigate the changes of plasma and urine metabolites in different liver diseases during the occurrence and development of liver cancer.
