Immunohistochemical expression of COX2 and iNOS in bladder cancer and its association with urinary schistosomiasis among Sudanese patients.

Aims: The purpose of this study was to determine if any relationship exists between expression of COX2 and iNOS markers and urinary schistosomiasis in bladder cancers.

Methodology: Immunohistochemical expression of COX2 and iNOS was assessed in formalin fixed paraffin wax processed tissues obtained from 155 patients with bladder cancers (87 SCC and 68 TCC) and 39 patients with benign bladder cystitis.

Results: The overall immune-expressions of COX2 and iNOS were 71.
