Patients with hepatocellular carcinoma can rarely survive up to twenty years after surgical resection, because many patients with hepatocellular carcinoma are already in the middle to late stage or progressive stage when they are diagnosed, and the prognosis is poor. For early stage liver cancer patients who choose surgery in time, the survival rate can reach 30%-50% in three years after surgery. For poorly differentiated liver cancer, the survival time varies from six months to one year after surgery, so the survival of liver cancer patients for twenty years after surgery is particularly rare and the incidence is very low. For malignant tumors of the liver, early diagnosis and surgery also require supplemental intravenous chemotherapy for the purpose of preventing recurrence and metastasis after surgery, and advanced patients can be controlled directly by intravenous chemotherapy or radio-interventional therapy.
