Symptoms of vomiting in advanced stage of liver cancer represent that the malignant tumor of the patient has spread to the patient’s digestive system, but how long the patient can live should be judged with the patient’s treatment effect. Hepatocellular carcinoma is a malignant tumor disease of liver, and patients will show clinical symptoms such as abdominal distension, jaundice, spider nevus and so on due to liver function damage and portal hypertension. The main reason for the different five-year survival rates of patients with advanced cancer is that the cancer cells of patients with advanced cancer spread widely and lack of effective means to completely eliminate the cancer cells. The widespread spread of cancer cells to the digestive system can lead to vomiting when the digestive system is damaged, but it is impossible to deduce the survival cycle of patients based on this alone, and it is necessary to further combine with the effectiveness of the patient’s radiotherapy, chemotherapy, interventional therapy and other treatments to determine this. Comparatively speaking, the five-year survival rate of patients with advanced cancer is relatively low, but through active treatment, it can help patients slow down the development of the disease and maintain the quality of life, so it is recommended that patients maintain an optimistic mindset and actively cooperate with doctors.
