Study on expression and clinical significance of ARD1 in nasopharyngeal carcinoma / 重庆医学

ABSTRACT

Objective To detect and explore the expression of ARD1 and its clinical significance in the nasopharyngeal in-flammatory tissue ,nasopharyngeal carcinoma group and its subgroups .Methods Expression of ARD1 in nasopharyngeal carcinoma (56 cases) and nasopharyngeal inflammatory tissue (20 cases) were detected by immunohistochemical staining SP ,the correlation between the expression of ARD1 and age ,gender ,histological grade ,TNM clinical stage and tumor metastasis were analysed . Results The positive expression rate of ARD1 were 10 .00% (2/20) ,55 .35% (31/56) in the nasopharyngeal inflammatory tissue and nasopharyngeal carcinoma ,respectively .The expression level of ARD1 in nasopharyngeal carcinoma was significantly higher than in the nasopharyngeal inflammatory tissue ,the difference was significant (P 0 .05) .Conclusion The expression of ARD1 is high in nasopharyngeal carcinoma ,and has a closely correlation with diffferentiation level of tumor ,which suggested that ARD1 may be involved in the the occurrence and development of nasopharyngeal carcinoma .However ,further research needs to be done for its mechanism in the nasopharyngeal car-cinoma .
