UHRF1 is associated with tumor recurrence in non-muscle-invasive bladder cancer.

Ubiquitin-like with PHD and ring finger domains 1 (UHRF1) is a novel anti-apoptotic gene, and overexpression of UHRF1 is involved in tumorigenicity. Here, immunohistochemistry was used to detect UHRF1 expression in non-muscle-invasive bladder cancer (NMIBC), and these data were examined for correlation with clinicopathological parameters and prognosis. The UHRF1 expression rate was 49.2% in a total of 118 bladder cancer tissues, which was significantly higher than in normal tissues, and UHRF1 expression has a significantly positive correlation with tumor grade (P = 0.027) and recurrence (P = 0.013). Survival analysis showed that UHRF1 high expression patients' mean survival time (42.59 months) was significantly shorter than that (71.36 months) of UHRF1 low expression patients (P = 0.0002). Multivariate analysis showed that UHRF1 overexpression was an independent prognostic factor for tumor recurrence (P < 0.0001). So UHRF1 may be a molecular marker to predict the recurrence of NMIBC.
