Purpose: The immunohistochemial markers can be used to predict prognosis more accurately for several cancers. In non-muscle invasive urothelial carcinoma, p53, c-erb-B2 and Ki-67 are applicable. We investigated a retrospective analysis of the relation between the markers and clinical prognostic factors of urothelial bladder cancer. Materials and Methods: Data from 268 non-muscle invasive urothelial bladder cancer (Ta, T1) patients from one single center were collected. Immunohistochemical evaluation was carried out on 268 (p53, c-erb-B2, Ki-67) cases. Clinical prognostic factors are as follows; number of tumor, tumor invasiveness, tumor grade and recurrence. The sum of all positivity of 3 markers was made as a new factor and evaluation of correlation between this factor and prognostic factors was also done. Statistical analysis was done by chi-squares test and Pearson’s correlation test. Results: Through chi-square test, there were significant relations between all markers and tumor invasiveness (p<0.001), tumor grade (p<0.001). Number of tumor is significantly related with Ki-67 (p=0.043). Recurrence is related with c-erb-B2 (p=0.010) and Ki-67 (p=0.043). There was also significant correlations between the sum of the markers and prognostic factors-tumor invasiveness (p<0,001), tumor grade (p<0.001) and recurrence (p=0.007). Conclusions: In this study, evaluated markers were closely related with clinical prognostic factors and may contribute to decision making on risk-assessment and management strategy for non-muscle invasive urothelial bladder cancer.
