The five-year survival rate of liver and lung metastasis of cardia and gastric body cancer is about 10% after treatment. Gastric cancer is a malignant tumor caused by heredity, bad dietary habits and other factors. When the disease develops to the late stage, it is often accompanied by distant metastasis, such as liver metastasis, in which clinical manifestations such as loss of appetite, nausea and vomiting, and pain in the liver area may appear. Depending on the patient’s specific situation, it can be decided whether tumor reduction surgery can be taken. However, non-surgical therapies such as palliative chemotherapy with 5-fluorouracil and capecitabine, radiation therapy for primary and metastatic lesions, and targeted drugs such as trastuzumab and apatinib are mostly used. After active treatment, a five-year survival rate of about 10% can be obtained. Therefore, when pancreatic cancer, gastric cancer liver and lung metastasis occurs, it is necessary to actively consult the doctor and follow the doctor’s instructions for reasonable treatment.
