CD10 and CA19.9 immunohistochemical expression in transitional cell carcinoma of the urinary bladder.

Background: Transitional cell carcinoma of the bladder is the most common malignancy affecting the urinary tract ranking the 5(th) among males and the 9(th) among females' cancers in Iraq. The prognosis depends largely on the histological grade and stage of the tumor at diagnosis; however, there is no reliable parameter predicting the risk of recurrence or progression; molecular and immunological markers may be required to estimate the individual prognosis of patients as well as for effective diagnosis and treatment.

Objectives: To evaluate CD10 and CA19.
