Gastric cancer is a common gastrointestinal malignancy, and the current treatment for hypofractionated gastric cancer is a combination of surgery as the mainstay and various treatments such as chemotherapy as a supplement. Surgery is an important aspect, and chemotherapy can further improve the survival rate. Generally speaking, the less differentiated the tumor is, the more malignant it is, relatively speaking. For hypofractionated gastric cancer, age less than 40 years old, cancer lesion area greater than 5cm, multiple cancers, chemotherapy is generally needed. Survival time has a lot to do with the stage of gastric cancer and other aspects, and each person’s physical condition is different, such as whether there is metastasis, diabetes and hypertension, so the survival period also varies from person to person. The main reason for this is the degree of development of the disease and the effect of the treatment.
