Abstract
Objective To study the expressions of Survivin and Bcl-2 in carcinoma of the ampulla of Vater and their clinical significance.Methods The expressions of Survivin and Bcl-2 proteins were tested by EnVision immunohistochemistry in 40 cases of ampullary carcinomas,and 8 cases of normal ampulla of rater as control.Results The positive expression of Survivin and Bcl-2 in the tissues from the ampullary carcinoma was significantly higher than that in the normal controls(82.5％,72.5％ vs 0％,12.5％,P ＜0.05).The expression of Survivin and Bcl-2 had no relations with the sex,age,tumor size,histological types,and clinical stages( P ＞ 0.05 ).The differences of the expression of Survivin and Bcl-2 in ampullary carcinoma of duodenal invasion,pancreatic invasion,and lymph node metastasis were significant(P ＜ 0.05) ; Significantly positive correlation was found between the expression of Survivin and Bcl-2 by using spearman correlation analysis( r =0.647,P ＜ 0.05 ).Conclusions Survivin and Bcl-2 may play an important role in tumorigenesis of ampullary carcinoma.Combined detection of Survivin and Bcl-2 may be useful to determine the degree of malignancy and the progress of the ampullary carcinoma. Key words: Carcinoma of the ampulla of Vater; Survivin ; Bcl-2 ; Immunohischemistry
