Abstract
PURPOSE
To investigate the association between the N-acetyltransferase 1 (NAT1) slow and rapid acetylation phenotypes with cancer risk based on a meta-analysis.
METHODS
Previously published case-control studies were retrieved from PubMed, Embase, and Web of Science. Odds ratios (ORs) with 95% confidence intervals (CIs) were determined to assess the relationship between NAT1 polymorphisms and cancer risk.
RESULTS
A total of 73 studies (24874 cases and 30226 controls) were included in this meta-analysis. No significant association was identified between NAT1 polymorphisms (slow acetylation versus rapid acetylation genotypes: OR = 0.978, 95% CI = 0.927-1.030, P < 0.001 for heterogeneity, I(2) = 45.5%) and cancer risk, whereas a significantly reduced risk of pancreatic cancer was identified in individuals with NAT1 slow acetylation genotype (OR = 0.856, 95% CI = 0.733-0.999, P =0.509 for heterogeneity, I(2) = 0). When the NAT1 slow acetylation genotype was analysed on the basis of stratified analyses of ethnicity, a significantly reduced risk of head and neck cancers was found among Asian (OR=0.281, 95% CI = 0.127-0.622). When the NAT1 slow acetylation genotype was analysed on the basis of stratified analyses of source of control, only significantly reduced risks of colorectal cancer (OR = 0.882, 95% CI = 0.798- 0.974, P = 0.212 for heterogeneity, I(2) = 22.9) and pancreatic cancer (OR=0.856, 95% CI = 0.733-0.999, P = 0.509 for heterogeneity, I(2) = 0) were found among hospital-based studies.
CONCLUSIONS
No significant association between the NAT1 polymorphisms and the risk of cancer was found except for pancreatic cancer.
