Artificial liver is also a kind of liver transplantation, and liver transplantation is usually not recommended for patients with liver failure in the advanced stage of liver cancer. The condition of patients with liver failure in the advanced stage of liver cancer is usually more serious, and the immunity and physical condition of the patients are relatively low, at this time, it is very risky to carry out liver transplantation, and the success rate is also lower. Moreover, patients with advanced liver cancer cannot be cured of liver cancer by liver transplantation alone, so liver transplantation is usually not recommended in such cases. In patients with advanced liver cancer, the cancer cells will metastasize to other organs and tissues outside the liver, and liver transplantation alone is not a way to remove the tumor cells that have spread outward. Patients with advanced cancer are mainly treated with maintenance therapy to improve their quality of life and prolong their survival time. For middle and early stage liver cancer patients whose tumor cells have not yet metastasized, liver transplantation can better remove the tumor cells, and the physical state of patients with advanced liver cancer is no longer suitable for artificial liver surgery.
