[Abstract]:Objective: to analyze the abnormal expression of 尾 -catenin in bladder cancer, and to evaluate systematically the relationship between the abnormal expression and the clinical, pathological features or prognosis of bladder cancer. To investigate whether 尾-catenin can be an effective pharmacological target in the treatment of bladder cancer. Methods: the "subject word free words" in the Chinese CNKI literature library 6.0 version (1996 ~ 12 September 2016), Weip Science and Technology Journal Library 6.5 (1989 ~ 2016 12 September, Chinese Biomedical Electronic Library CBM) (1978 ~ 12 September 2016) Universal data Journals, papers, etc.) platform (1988-12 September 2016 / CDSR / Cochrane systematic Review Electronic Library (2016-1) / EMBase (1974-Sept. 12, 2016) and Google academic Web site search, and manual search of journal publications, As of September 12, 2016. According to the MOOSE / 2000 version), the system evaluation process was completed. The general information of each CCS (case-control study) was qualitatively summarized and analyzed, and the quantitative analysis of the data was carried out with the Revman manager version 5.3. The results were evaluated with OR value and HR value of 95% CI, with Chi2 test, P value as heterogeneity result, and with Z test with P value to evaluate bias. Results: the CCS records were included in 13 study records, including 862 bladder cancer patients and 76 normal bladder mucosa patients. The expression of 尾 -catenin in bladder cancer group was higher than that in normal bladder mucosa group (7.61-50.48); OR = 19.60; P 0.00001, the difference was statistically significant. The expression level of 尾 -catenin in the high grade cystadenocarcinoma group was higher than that in the low grade bladder cancer group (2.89-5.71; OR = 4.06; P 0.00001, P 0.00001). The expression level of 尾 -catenin in the high grade cystadenocarcinoma group was higher than that in the lower grade bladder cancer group (2.89-5.71; OR = 4.06; P 0.00001, the difference was statistically significant) 尾 -catenin expression and 尾 -catenin expression in the high grade cystadenocarcinoma group were higher than those in the lower grade bladder cancer group. There was no significant correlation between sex (95 CI = 0.57, 1.96 or = 1.06; P = 0.85, P = 0.85). There was no significant correlation between 尾 -catenin expression level and the number of tumors (multiple / single). There was no significant correlation between 95 CI = 0.36% 1.88); OR = 0.82; P = 0.63N, there was no significant difference between 尾 -catenin expression and tumor number (multiple / single); OR = 0.82; P = 0.63N, there was no significant difference in 尾 -catenin expression. The level of PFS was significantly correlated with PFS), HR = 2.74 and P = 0.01, respectively. Conclusion: the results of Meta-analysis indicate that the expression of 尾 -catenin in bladder cancer is higher than that in normal bladder mucosa, that is, the high expression of 尾 -catenin may be related to the occurrence of bladder cancer. With the increase of 尾 -catenin expression, the higher TNM stage and pathological grade of bladder cancer were, the shorter the PFS was, but there was no significant correlation between the number of bladder cancer tumors and the sex. These results suggest that 尾-catenin may be a biomarker for the diagnosis of bladder cancer.
