For patients who have undergone surgery for cardia cancer, generally due to the different clinical stages, pathological malignancy, physical strength score, etc., and thus there are differences in the survival time of the patients, generally the five-year survival rate of early-stage patients is about 85%, and that of mid-stage and locally advanced-stage patients is about 60%~70%. Early stage pancreatic cancer generally refers to patients with stage I. Most patients can achieve clinical cure after radical surgery, and the five-year survival rate of patients is about 85%, which means that many patients can survive for five years or more. Intermediate stage generally refers to patients with stage II, and locally advanced stage generally refers to patients with stage III. The five-year survival rate of patients after surgery is between 60% and 70%, indicating that more than half of the patients can also survive for about five years.
