Hepatocellular carcinoma combined with intrahepatic metastasis usually suggests that the tumor has invaded the portal vein or hepatic vein, and it belongs to the progressive or advanced stage of hepatocellular carcinoma. The Chinese staging plan for liver cancer (CNLC) is established based on the patient’s physical activity status (PS), liver tumor and liver function, taking into account the specific conditions of China and the accumulation of practice, and classifies liver cancer into stage Ia, Ib, IIa, IIb, IIIa, IIIb and IV, which is of great value for evaluating the prognosis and treatment options. Hepatocellular carcinoma combined with intrahepatic metastasis usually suggests that the tumor has invaded the portal vein or hepatic vein, and according to the domestic guidelines, it is at least CNLC stage IIIa, and may also be CNLC stage IIIb or CNLC stage IV: 1. CNLC stage IIIa: PS score 0~2, liver function Child-Pugh grade A/B, regardless of tumor status, with vascular thrombus visible on imaging and no extrahepatic metastasis. 2. CNLC stage IIIb: PS score 0~2, liver function Child-Pugh class A/B, regardless of tumor status, with or without vascular thrombus and extrahepatic metastasis. 3. CNLC stage IV: PS score 3~4, or liver function Child-Pugh grade C, regardless of tumor status, with or without vascular thrombus, with or without extrahepatic metastasis. If liver cancer is diagnosed, it is recommended to go to regular hospitals to evaluate the condition in time and follow the doctor’s instructions for treatment to avoid delaying the condition.
