Gastric cancer is likely to be cured, especially early gastric cancer, and patients can be cured by surgical resection of the lesion. If it is advanced gastric cancer, the patient may have cancer cell metastasis and serious complications. The possibility of cure at this time is low, and the five-year survival rate is less than 10%. When cancer cells metastasize in patients with gastric cancer, chemotherapy and radiotherapy should be combined to control infection, which can also improve the quality of life of patients. When patients with gastric cancer receive radiotherapy and chemotherapy, their immunity may decrease, so they should eat more high-protein foods. At present, Japan's WT 1 tumor vaccine is also very good. WT 1 killer T lymphocytes find cancer markers (WT 1 peptide) on the surface of cancer cells and attack cancer cells to kill them. Because there is no WT 1 peptide on the surface of normal cells, normal cells will not be attacked. Qingdao Hankang International Medical is responsible for the operation of Japanese WT 1 tumor vaccine in China.
