Prognostic significance of E-Cadherin and B-Catenin in non-muscle invasive bladder cancer

ABSTRACT

Non muscle invasive bladder cancer (NMIBC) has unpredictable outcomes with a variable risk of recurrence and progression. Many clinic-pathological prognostic factors have been identified but remain insufficient, raising the need to investigate new biomarkers. The aim of our study was to assess the prognostic value of the immunohistochemical (IHC) markers E-Cadherin and B-Catenin in NMIBC. All cases of NMIBC were collected between 2008 and 2013. IHC analysis was performed using E-Cadherin and B-Catenin. Reduced or loss of E-Cadherin expression was assessed as abnormal. Only cases with B-Catenin intense membranous staining were considered normal. A correlation was found between abnormal E-Cadherin expression and stage (p = 0.001), grade (p = 0.0000000), recurrence (p = 0.0000000), progression (p = 0.01), recurrence-free survival (p = 0.00000001), and progression-free survival (p = 0.01). A statistically significant association was found between B-Catenin and stage (p = 0. 05), grade (p = 0.02), and recurrence (p = 0.02). The abnormal expression of these markers could help to identify a high-risk subgroup of NMIBC that might benefit from either more accurate follow-up or more aggressive treatment.
