Level Changes and Significance of IL-2, IFN-γ and TNF-α in Bladder Cancer Patients / 现代生物医学进展

ABSTRACT

Objective:To discuss the level changes and significance of IL-2,IFN-γ,TNF-α in patients with bladder cancer.Methods:66 patients with bladder cancer who were treated in our hospital from February 2015 to December 2016 were enrolled in this study,which was denoted by bladder cancer group,65 patients with cystitis glandularis who were treated in our hospital during the same period were selected as cystitis group,another 65 healthy persons who were examined in our hospital during the same period were selected as control group,and compared the levels of IL-2,IFN-γ and TNF-α in each group,and the levels of IL-2,IFN-γand TNF-α in patients with bladder cancer of different types and clinical stages.The correlation of IL-2,IFN-γ and TNF-α levels with pathological types and clinical stages were analyzed.Results:The levels ofIL-2 and INF-γ in bladder cancer group were significantly lower than those in cystitis group and control group,the level of TNF-α was significantly higher than that of cystitis group and control group,the difference was statistically significant (P＜0.05).There was no significant difference in IL-2,IFN-γ and TNF-α levels in different types of bladder cancer patients (both P＞0.05).IL-2,IFN-γ levels in T2 to T4 bladder cancer patients were significantly lower than Tis to T1,TNF-α level was significantly higher than Tis to T1,the difference was statistically significant (both P＜0.05).According to Spearman method evaluation correlation founded that IL-2,IFN-γlevels in patients with bladder cancer were negatively correlated with clinical stage,TNF-α level was positively correlated with clinical stage.However,there was no correlation between IL-2,IFN-γ and TNF-α levels in patients with pathological type.Conclusion:IL-2,IFN-γ expression in bladder cancer patients are decreased significantly,while TNF-α expression is increased significantly,and the above three indexes of patients are related to clinical stage,but not related to pathological type.
