The prognosis of transitional cell carcinoma(TCC) of the urinary bladder is related to histopathologic parameters, among which the clinical stage and histopathologic grade are most important prognostic determiantors. Recently the immunohistochemical assessment of proliferating cell nuclear antigen(PCNA) and nucleolar organizer region number(AgNORs) can obtain the PCNA, and AgNORs stainings were studied in 55 the sequential biopsies of 22 recurrent TCCs of the urinary bladder. 6 cases showed the increased changes of grade, of which 5 cases was independently to the change of grade. The AgNORs in 18 cases showed increase in 10 cases. The comparison between PCNA count and AgNORs score according to grade was performed in the changes between grade II and III, both PCNA count and AgNORs score were increased with in crease of grade. However, The change of the PCNA count was stastically significant, but not AgNORs score.
