Background: Many studies have evaluated the correlation between N-acetyltransferase 2 (NAT2) slow acetylation genotype and bladder cancer risk. However, the results are inconsistent and remain to be confirmed in each ethnic group. To assess the effects of NAT2 acetylation status on the risk of bladder cancer in the Chinese population, a meta-analysis was performed.
Methods: Studies were identified using PubMed and Chinese databases through February 2016. The associations were assessed with pooled odds ratios (ORs) and 95% confidence intervals (CIs).
Results: This meta-analysis included 10 studies with 896 bladder cancer cases and 1188 controls. In the overall analysis, NAT2 slow acetylation phenotype was significantly associated with an increased risk of bladder cancer in the Chinese population (OR = 1.68, 95% CI = 1.11 - 2.53). In the subgroup analyses by geographic areas and sources of controls, significant risk was found in Mainland China (OR = 1.83, 95% CI = 1.04 - 3.20) and hospitalbased studies (OR = 1.74, 95% CI = 1.27 - 2.38), but not in Taiwan China.
Conclusions: This meta-analysis suggested that the NAT2 slow acetylation genotype is associated with an increased bladder cancer risk in Chinese individuals.
