Abstract:
Previous data on association between CYP2E1 Rsa I/Pst I polymorphism and oral cancer risk were controversial. To investigate the association between CYP2E1 Rsa I/Pst I polymorphism and oral cancer risk. We performed a meta-analysis to assess the relationship between oral cancer and genotype with English language until June 2010. Twelve published case-control studies of 1259 patients with oral cancer and 2262 controls were acquired. Odds ratios (ORs) with 95% confidence intervals (CIs) were used to assess the strength of the association in codominant and dominant models. Overall, the pooled ORs indicated a significant association between CYP2E1 Rsa I/Pst I polymorphism and oral cancer risk (for c1/c2 vs. c1/c1: OR=1.30, 95% CI=1.04-1.62, Pheterogeneity=0.57; for (c1/c2+c2/c2) vs. c1/c1: OR=1.32, 95% CI=1.07-1.64, Pheterogeneity=0.57, respectively). In subgroup analysis by race, the same significant risks were found among Asian (for c1/c2 vs. c1/c1: OR=1.41, 95% CI=1.05-1.91, Pheterogeneity=0.92; for (c1/c2+c2/c2) vs. c1/c1: OR=1.43, 95% CI=1.08-1.88, Pheterogeneity=0.97, respectively). In conclusion, this meta-analysis demonstrates that CYP2E1 Rsa I/Pst I c2 allele may be a biomarker for oral cancer, especially among Asian populations.
