Abstract:
Objective To study the expressions of survivin and PTEN in ampullary carcinoma and their clinical significance.Methods The expressions of Survivin and PTEN proteins were tested by EnVision immunohistochemistry in 40 cases of ampullary carcinomas and 8 cases of normal ampulla of vater as control.Results The positive rate of Survivin in ampullary carcinomas was significantly higher than normal human controls (82.5％ vs 0％,P ＜ 0.01 ).The differences of the expression of Survivin in ampullaty carcinoma of duodenal invasion,pancreatic invasion,and lymph node metastasis were significant ( P ＜0.05 ).Significant differences were also observed in the expression rate of PTEN hetween the patients with ampullary carcinoma and the normal controls (50％ vs 100％,P ＜ 0.01 ).The differences of the expression of PTEN in ampullary carcinoma of duodenal invasion,pancreatic invasion,and lymph node metastasis were significant ( P ＜ 0.05 ).Significantly negative correlation was found between the expression of Survivin and PTEN by using spearman correlation analysis ( r =-0.57,P ＜ 0.01 ).Conclusions The abnormal expression of Survivin and PTEN gene may promote tumor genesis and progression of ampullary carcinomas and it may be used as the marker for prognosis.
