[Expression of cyclooxygenase-2 in bladder transitional cell carcinoma and the significance thereof].

Objective: To study the expression of cyclooxygenase-2 (COX-2) in bladder transitional cell carcinoma (Tcc) and the clinical significance thereof.

Methods: Immunohistochemistry was used to detect the expression of COX-2 in 56 specimens of bladder Tcc and 10 specimens of normal bladder tissue, all resected during operation.

Results: No expression of COX-2 was detected in the 10 specimens of normal bladder tissue and in the 56 specimens of bladder Tcc the positive rate of COX-2 was 55.
