In the late stage of liver cancer, treatment depends on the specific circumstances. If there is significant ascites or severe liver function damage, treatment may primarily involve optimal supportive care. If the patient's liver function is relatively good, such as in hepatocellular carcinoma, targeted therapy may be an option. If the patient's overall condition allows, other treatment methods such as chemotherapy and immunotherapy may be considered. Furthermore, if the pathology is cholangiocarcinoma with jaundice as the main symptom, a stent can be placed externally in the biliary tract to drain bile and alleviate jaundice symptoms. If there is no portal vein thrombosis, no significant ascites, and multiple liver metastases are present, chemotherapy embolization of hepatic veins and various local ablation treatments can also be considered. Thus, the specific approach should take into account multiple factors such as the patient's constitution, overall condition, and the severity of liver function impairment.
