Abstract:
Objective To explore the relationship between polymorphism of miR-499A > G with inci-dence and prognosis of colorectal cancer in Han Chinese. Method 1:1 matched case control study was used to collect samples,and the patients were followed up. The genotypes distribution miR-499A > G were detected by TaqMan probe,and logistic regression model and Cox proportional hazard regression model were used to analysis the relationship between miR-499A>G and incidence and prognosis of colorectal cancer. Results 394 cases and 394 controls were recruited,while miR-499A>G did not increase the risk of colorectal cancer(OR=1.22,95%CI:0.95-1.57)under additive model analyzed by multi-logistic regression model. The means of survival time of AA,AG,GG carriers were 54.19 ± 2.02,44.16 ± 2.59,32.76 ± 5.36 months and there were significant differentia-tion between them in log Rank test(F=11.24,P=0.004). Cox proportional hazard regression model showed that miR-499A > G was significant associated with adverse prognosis of colorectal cancer(HR=1.26,95%CI:1.02-1.57). Conclusion miR-499 A > G has no association with the incidence of colorectal cancer ,but it affects the prognosis of colorectal cancer in Han population.
