Expression level of ZNF217 in bladder cancer and its clinical significance

Abstract

Objective To determine the expression of ZNF217 protein in bladder cancer tissues and to analyze its clinicopathological characteristics, so as to clarify its clinical significance. Methods The clinicopathological data of 123 patients with bladder cancer who underwent bladder cancer resection were retrospectively analyzed. The expression of ZNF217 protein in bladder cancer tissues and corresponding adjacent tissues was detected by immunohistochemistry, and its correlation with clinical characteristics of patients was analyzed. Results ZNF217 protein was highly expressed in tumor tissues, and the ratio of high expression of tumor tissues was 67.4%, but it was lowly expressed in adjacent tissues. By comparing with clinicopathological features, the expression level of ZNF217 was significantly correlated with tumor T stage and tumor recurrence (all P 0.05). The survival analysis showed that patients with high expression of ZNF217 in bladder cancer had significantly shorter overall survival and progression-free survival than those with low ZNF217 expression (all P<0.05). Conclusions ZNF217 is highly expressed in bladder cancer tissues, and its expression level is associated with tumor stage, tumor recurrence and poor prognosis, suggesting that it can be used as a potential therapeutic target for bladder cancer.
