Whether surgery is necessary for eighty-year-old gastric cancer patients once they are diagnosed depends mainly on the patient’s physical quality and the pathological stage of gastric cancer. In the case of eighty-year-old patients, if they do not have obvious cardio-cerebral vascular diseases, have good physical condition and quality, and the gastric cancer is in early stage I or II, they should try to adopt the surgical treatment plan. Before surgery, the patient’s cardiopulmonary function and the patient’s basic indexes should be fully evaluated, and through effective surgical means, the survival and cure rate of gastric cancer patients can be improved. However, for older people or those who have heart, lung or cerebrovascular accidents, if they have gastric cancer, such cases are not suitable for surgical treatment and can be treated conservatively, which can reduce patients’ risk of surgery.
