For patients with malignant tumor of liver, the symptoms that appear in the middle and late stages are mainly as follows: 1. Patients may develop hepatic encephalopathy. Patients in the middle and late stages have poor liver function, and most of them have combined peritoneal cavity effusion and systemic malignant performance. In this case, if the patient eats more fatty food or high protein diet, it will trigger the possibility of hepatic encephalopathy. If the patient has upper gastrointestinal bleeding, it may also trigger the possibility of hepatic encephalopathy, which is a cause of death. 2. For patients with hepatocellular carcinoma, the possibility of liver failure may occur in the advanced stage. Such patients will have a sharp increase in glutamic and glutamic oxalacetic aminotransferases and a sharp increase in jaundice index, which may lead to liver failure.
