Expression of Survivin in pancreatic cancer and its correlation to expression of Bcl-2.
OBJECTIVE
To investigate the expression of Survivin in pancreatic cancer and its correlation to the expression of Bcl-2.


METHODS
Survivin and Bcl-2 expressions were examined by immunohistochemistry in 42 tissue samples from pancreatic cancer and 10 from normal pancrease.


RESULTS
No survivin expression was detected in the tissue samples from normal pancrease, while it was detected in 34 of 42 tissue samples from pancreatic cancer (81.95%). There was a correlation between survivin expression and differentiation and stages of pancreatic cancer. Survivin positive cases were strongly correlated to Bcl-2 expression (28/30 vs 6/12, P<0.05).


CONCLUSIONS
Overexpression of survivin plays an important role in the development and progression of pancreatic cancer, and correlates to the expression of Bcl-2. Survivin expression can be used as a prognostic factor.
