| Abstract | AIMS: This study is designed to evaluate the expression and prognostic value of FGFR3 protein expression in patients with pTa/pT1 tumours and to determine the significance of the combinations of FGFR3 and p53 protein expressions in bladder pathogenesis. MATERIALS AND METHODS: A tissue microarray (TMA) of 107 pTa, and 147 pT1 tumours was constructed. The TMA sections were immunostained with FGFR3 and p53 monoclonal antibodies. RESULTS: There were significant associations between loss of FGFR3 and tumour stage (p<0.001) and grade (p<0.001) and between p53 overexpression and tumour stage and grade (p<0.001 and p<0.001, respectively). There was no association between FGFR3 and p53 proteins (p=0.107). In addition, tumours with FGFR3+/p53- phenotype have slower recurrence rate than other (FGFR3+/p53+, FGFR3-/p53- and FGFR3-/p53+). CONCLUSION: 1-FGFR3 expression is significantly associated with two important prognostic factors; stage and grade. 2-FGFR3 protein expression is not an independent predictive factor for pTa/pT1 tumour recurrence and progression. 3-Tumours with FGFR3+/p53- phenotype seem to have a distinctive pathway in bladder tumorigenesis. | |
