Radical hepatocellular carcinoma surgery means: ① complete resection of tumor seen by the naked eye with no cancer at the cut edge; ② no more than 2 tumors; ③ no cancerous thrombus in the main trunk and primary branches of portal vein, common bile duct and primary branches, hepatic vein and inferior vena cava; ④ no metastasis in hilar lymph nodes; ⑤ no extra-hepatic metastasis; ⑥ AFP drops to normal within 2 months after surgery (for those with positive AFP before surgery); ⑦ no tumor seen on imaging within 2 months after surgery residual or recurrent metastasis. Palliative hepatocellular carcinoma surgery refers to the removal of part or most of the tumor tissue. After surgery, anti-tumor treatment should be strengthened, including super-color intervention of residual tumor such as anhydrous alcohol injection, radiological intervention and intra-abdominal chemotherapy drug infusion, in order to delay the invasive growth and spread of residual tumor as much as possible.
