Gastric hypofractionated adenocarcinoma refers to the pathological type of gastric cancer as hypofractionated adenocarcinoma. How long a patient can live with gastric cancer is related to the stage of gastric cancer, and the 5-year survival rate after early surgery is about 80%, while the 5-year survival rate after intermediate and late surgery is about 5%-20%. Under normal circumstances, the more advanced the pathological stage is, the lower the 5-year survival rate of patients. For early-stage gastric cancer patients, the clinical prognosis is generally good with a 5-year survival rate of about 80% through radical surgical resection of the cancer lesion and subsequent adjuvant chemotherapy treatment. However, for patients with middle and late stage gastric cancer, cancer cells have metastasized and spread, the prognosis of tumor is relatively poor, and the survival time is significantly reduced, so control treatment can only be adopted for the purpose of prolonging patients’ survival time. Therefore, clinical emphasis is placed on early detection, early diagnosis and early treatment of cancer to improve the overall survival prognosis. For cancer patients, good daily living, psychological and nutritional care can play a positive role in improving patients’ survival time and quality of life.
