The spread of stomach cancer to the lungs and liver indicates that it is advanced stomach cancer, which is very advanced and the overall survival period is very short, estimated to be around 6 months. If the patient is treated a little better, it is possible to be around 1 year. Stomach cancer is more likely to have lymph node metastasis as well as blood metastasis, and if there is blood metastasis, it is especially likely to metastasize to the liver or lung. If it metastasizes to the liver, patients will have vague pain and swelling in the liver area, and will have elevated transaminases, elevated bilirubin, hypoproteinemia, and so on. If it metastasizes to the lung, patients may have hemoptysis, chest pain, chest tightness, and may even have pleural effusion, dyspnea, and other symptoms, with a relatively short survival period. However, targeted therapy plus chemotherapy can also be used to treat the disease, and if the treatment effect is better, the patient’s survival time can be extended. If the treatment is not effective, the overall survival time of the patient may be about 6 months.
