Abstract:
Objective To investigate the relationship between the expression of Krüppel-like factor 5(KLF5)and lysine demethylase 2A(KDM2A)in cancer tissues of patients with oral cancer and clinicopatho-logical characteristics and prognosis.Methods Cancer tissues of 80 patients with oral cancer who underwent surgical treatment in the Zigong First People's Hospital from January 2015 to January 2018 were retrospec-tively collected as research objects,and normal adjacent tissues were selected as controls.The expression of KLF5 and KDM2A in cancer tissues and adjacent tissues of patients with oral cancer was detected by immuno-histochemical staining,and the correlation between KLF5 and KDM2A in cancer tissues was analyzed by Spearman correlation.Clinicopathological features of patients with oral cancer were collected,and the relation-ship between the expression of KLF5 and KDM2A in cancer tissues and clinicopathological features of patients was analyzed,as well as the prognostic factors of patients with oral cancer were analyzed by multivariate Cox regression.Kaplan-Meier method was used to analyze the relationship between the expression of KLF5 and KDM2A and the prognosis of patients with oral cancer.Results The high expression rates of KDM2A and KLF5 in oral cancer tissues were significantly higher than those in adjacent tissues,and the difference was sta-tistically significant(P＜0.05).Spearman correlation analysis showed that there was a positive correlation be-tween KLF5 and KDM2A expression in oral cancer patients(r=0.375,P＜0.05).The expressions of KLF5 and KDM2A in patients with oral cancer were correlated with TNM stage,clinical stage,lymph node metasta-sis,local invasion and differentiation degree(P＜0.05).Multivariate Cox regression analysis showed that the expression level of KLF5 and KDM2A,TNM stage,lymph node metastasis,local invasion and differentiation degree were independent risk factors for poor prognosis in patients with oral cancer(P＜0.05).The 5-year survival rates of patients with high expression of KLF5 and KDM2A in cancer tissues[38.88％(21/54),42.37％(25/59)]were lower than those of patients with low expression of KLF5 and KDM2A in cancer tis-sues[65.38％(17/26),61.90％(13/21)],the difference was statistically significant(x2=6.554,4.046,P＜0.05).Conclusion The expression of KLF5 and KDM2A in cancer tissues of patients with oral cancer is high and affects the prognosis of patients.
