The specimens of pancreatic cancer and its adjacent tissues were selected from 72 patients who were surgically removed and confirmed by pathology. The expression level of KIF4A protein in each group was detected by immunohistochemistry. Compare the expression of KIF4A in pancreatic cancer and its relationship with clinical parameters. Kaplan Meier method was used to analyze the relationship between the expression of KIF4A and the prognosis of patients. Cox proportional risk model was used to analyze the prognosis of pancreatic cancer.
