Gastric cancer cells metastasized to liver cancer is advanced stage, the 5-year survival rate is less than 20%, often the survival time is around 1 year, but the exact survival time is related to the condition. Liver is one of the common metastatic sites of gastric cancer. Liver metastasis is a manifestation of progressive or advanced gastric cancer, and the treatment needs to choose an appropriate plan after comprehensive evaluation. 1. If the metastatic lesion is located in a small lobe of liver or an isolated lesion with small diameter, and the general condition is good enough to tolerate surgery, surgery can be chosen to resect the lesion, and medication can be assisted after surgery. 2. If the metastatic foci are large in size or number, and surgery is difficult, radiofrequency ablation or hepatic artery chemoembolization can be chosen. If it is difficult to tolerate radiofrequency ablation or hepatic artery embolization, chemotherapy or traditional Chinese medicine can be chosen according to the needs of the disease to control tumor growth and prolong the survival period. 3. If patients have serious systemic symptoms, poor general condition, multiple organ and tissue metastases throughout the body, and difficult to tolerate surgery, chemotherapy and radiotherapy, they can choose targeted therapy, nutritional support, albumin supplementation and other treatments in order to reduce clinical symptoms and improve quality of life. However, gastric cancer metastasis to liver is already in advanced stage, and its prognosis is related to the primary lesion, the condition of liver metastasis and the treatment mode. Its prognosis is related to the primary lesion, liver metastases and treatment modalities. The specific prognosis is still inconclusive, and some studies claim that its 5-year survival is only 16.3%. In conclusion, the prognosis of patients with liver metastasis of gastric cancer is poor. It is recommended to go to regular hospitals to evaluate the condition and follow the doctor’s instructions to control the disease progression and improve the prognosis of patients.
