1. General condition of the patient (1) the patient is in good general condition, no significant organic lesions of the heart, lungs, kidneys and other important organs; (2) normal liver function, or only mild damage, according to the liver function classification is é grade; or liver function classification is ê grade, after short-term liver care treatment has significantly improved, liver function back to é grade; (3) liver reserve function (such as ICG, r15) normal range; (4) no extensive extrahepatic metastatic tumor. 2. Local lesions The following cases are feasible for radical hepatectomy (5) single microscopic hepatocellular carcinoma (diameter ≤50px); (6) single small hepatocellular carcinoma (diameter >50px, ≤125px); (7) single large hepatocellular carcinoma (diameter >125px, ≤250px) or giant hepatocellular carcinoma (diameter >250px) growing outside the liver with smooth surface and clear peripheral boundary. (8) multiple tumors with less than 3 tumor nodules confined to one segment or lobe of the liver; the following cases can only be treated with palliative hepatectomy. (10) Large hepatocellular carcinoma (diameter >125px, ≤250px) or giant hepatocellular carcinoma (diameter >250px) in the left or right half of the liver with clear borders and no invasion of the first and second hepatic hilum; imaging shows that the tumor-free side of the liver has obvious compensatory enlargement, reaching more than 50% of the whole liver tissue; (11) Large hepatocellular carcinoma located in the central region of the liver (middle lobe of the liver, or ìíD segmentî), (11) Large hepatocellular carcinoma located in the central region of the liver (middle lobe, or ìíD segment), with significant compensatory enlargement of tumor-free liver tissue, reaching more than 50% of the whole liver (12) Large hepatocellular carcinoma or giant hepatocellular carcinoma of é or D; (13) Lymph node metastasis in the hilar region, if the primary liver tumor can be resected, the tumor should be resected and the lymph nodes in the hilar region should be cleared at the same time; if the lymph nodes are difficult to be cleared, radiation therapy can be performed after surgery; (14) Invasion of surrounding organs (colon, stomach, diaphragm or right adrenal gland, etc.), if the primary liver tumor can be resected, the tumor and the invaded organs should be removed together. If the primary liver tumor is resectable, it should be removed together with the tumor and the invaded organs. For single metastatic tumor of distant organs (e.g. single lung metastasis, resection of primary liver cancer and metastasis can be performed simultaneously)
