The survival rate of pancreatic cancer patients is shown in the following aspects: First, if pancreatic cancer is early gastric cancer, patients have a better prognosis, and the five-year survival rate of intra-mucosal cancer is about 90% or even 100%. If the cancer of cardia is submucosal cancer, the five-year survival rate is about 80%-90%. Third, the prognosis of intermediate stage cardia cancer invading the muscular layer is better than advanced gastric cancer invading the plasma membrane or outside the plasma membrane, and the five-year survival rate of intermediate gastric cancer is about 30%-80%, with an average of 70%, while the five-year survival rate of advanced cardia cancer is only about 20%-30%. Therefore, it is recommended that patients must be detected and treated early, and early treatment is more effective.
