Expression and clinical implication of TGF-? and TGF-?1 in pancreatic carcinoma / 中国现代普通外科进展

ABSTRACT

Objective:To explore the expression of TGF-?,TGF-?1 in the tissues of pancreatic adenocarcinoma and normal pancreas,and study the changes and the relationships with the clinicopathological parameters of pancreatic adenocarcinomas.Methods:The expressions of the TGF-?,TGF-?1 were assayed in formalin-fixed paraffin embedded samples of 41 patients with pancreatic adenocarcinoma and 12 normal pancreatic tissues by means of SABC immunohistochemistry.The relationships between the expression and clinical parameters were analysied,such as ages,gender,tumor size,location,degree of differentiation and stage(UICC).Results:The positive rate of TGF-?,TGF-?1 were73.2%,63.4% respectively in pancreatic adenoeareinoma and were16.7 %,25% respectively in normal pancreatic tissues.Significant differences were found between the two groups(P
