After treatment, the five-year survival rate of secondary liver cancer patients is less than 5% to more than 20%, which needs to be analyzed in the light of their conditions. Liver cancer can be categorized into primary and secondary liver cancer, of which the latter is mostly caused by liver metastasis when other cancers develop into advanced stage. The latter is mostly caused by liver metastasis when other cancers develop into advanced stage. At this time, advanced stage patients are often accompanied by multiple distant metastases and have poor physical condition. The primary lesions of secondary liver cancer are mostly from primary tumors of gastrointestinal, pancreatic, breast, lung and other organs. The treatments for secondary liver cancer are mostly non-surgical therapies such as radiotherapy, chemotherapy and targeted therapy. After active treatment, the specific five-year survival rate of patients is highly related to the type of primary malignant tumor, such as lung cancer is about 5%, pancreatic cancer is less than 5%, nasopharyngeal cancer is about 15%, and gastrointestinal cancer is more than 20%.
