The prognostic value of P-cadherin in non-muscle-invasive bladder cancer

ObjectivesThis research aims to specify the prognostic value of P-cadherin on recurrence and progression in non-muscle-invasive bladder cancers (NMIBC).MethodsA total of 110 NMIBC cases were collected and P-cadherin protein was assessed by immunohistochemical test in these samples. Correlations between P-cadherin expression and clinicopathologic features were analyzed. For recurrence-free and progression-free survival, Kaplan–Meier log-rank test was used. Then Cox univariate and multivariate analyses were further performed.ResultsP-cadherin high expression correlated with tumor progression (P = 0.031). Kaplan–Meier results showed that patients with high P-cadherin expression had worse progression-free survival (P = 0.034) but not recurrence-free survival (P = 0.133) than low-expression patients. Cox regression results showed P-cadherin expression was an independent predictor for progression (P = 0.042) but not recurrence (P = 0.139) in NMIBC.ConclusionsOur results demonstrated that P-cadherin expression correlated with tumor progression and could be taken as an independent predictor for progression in NMIBC.
