Hepatocellular carcinoma, i.e. malignant tumor of the liver, can be divided into two categories: primary and secondary. Primary liver malignancies originate from the epithelial or mesenchymal tissues of the liver. The former is called primary liver cancer, which is a highly prevalent and dangerous malignancy in China; the latter is called sarcoma, which is less common compared with primary liver cancer. Secondary or metastatic hepatocellular carcinoma refers to the invasion of malignant tumors from multiple organs of the body to the liver. It is usually seen in the liver metastasis of malignant tumors of stomach, biliary tract, pancreas, colorectum, ovary, uterus, lung, breast and other organs. (1) Complete remission: the tumor disappears and lasts for more than one month. (2) Partial remission: the product of the two largest mutually perpendicular diameters of the tumor is reduced by more than 50% and lasts for more than one month. (3) Stable: The product of two largest mutually perpendicular diameters of the tumor shrinks less than 50%, and the enlargement does not exceed 25% and lasts for more than one month. (4) Deterioration: The product of two largest mutually perpendicular diameters of the tumor increases by no more than 25%. 2. The change of AFP content is used as the criterion to measure the efficacy. Postoperative AFP decrease to normal is the basis of surgery is radical. 3.The survival period after treatment is the criterion to measure the efficacy. The length of patient survival after treatment reflects the final effect of treatment, so it is the most valuable efficacy standard.
