Metastatic hepatocellular carcinoma refers to secondary hepatocellular carcinoma. The survival period of secondary hepatocellular carcinoma cannot be generalized and needs to be judged by a combination of various factors, generally the 5-year survival rate is <1%. Secondary liver cancer refers to malignant tumors in other parts of the body, which metastasize to the liver through blood, or tumors in neighboring organs directly invade the liver. Most patients have symptoms caused by primary cancer, and symptoms caused by the liver itself may not be obvious, although some patients may also have symptoms such as pain in the liver area, epigastric mass and jaundice. Secondary liver cancer belongs to the advanced stage of malignant tumors, and the prognosis of cancer metastasis is not ideal, most patients have shorter survival period, generally the 5-year survival rate is <1%. Patients should actively accept doctors' chemotherapy, radiotherapy, targeted drugs and other comprehensive treatments, which can also prolong their lives, so it is impossible to judge the survival period of metastatic liver cancer purely.
