Relationship between environmental exposures,genetic polymorphism of NAT2 and colorectal cancer / 肿瘤研究与临床

ABSTRACT

Objective To explore the relationship between NAT2 genetic polymorphism and the risk of colorectal cancer. Methods A hospital-based case-control study was conducted and polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method was used to detect its genotypes.Results The frequency of NAT2 slow genotype was 19.58% in cases with colorectal cancer compared.with increased the risk for developing colorectal cancer and their OR were 2.16(95% CI:1.31～3.54).Conclusion The results suggest that NAT2 genetic polymorphism is associated with colorectal canoer susceptibility.People with NAT2 slow genotype have higher coloreetal cancer risk.
