Excerpt
We read with great interest the paper entitled “No association between XRCC1 gene Arg194Trp polymorphism and risk of lung cancer: evidence based on an updated cumulative meta-analysis” published in
Tumor Biol. 2014, 35: 5629–5635 [
1]. Zhang et al. performed a meta-analysis to explore the association between X-ray repair cross-complementing group 1 (XRCC1) Arg194Trp polymorphism and lung cancer risk on the basis of 25 case-control studies with 8876 cases and 11,210 controls. The authors found that XRCC1 Arg194Trp polymorphism was not associated with lung cancer risk [odds ratio (OR) = 0.97 with 95 % confidence interval (95 %CI): 0.92–1.03 for Trp vs. Arg; OR = 0.92 with 95 %CI: 0.85–0.98 for Arg/Trp vs. Arg/Arg; OR = 1.07 with 95 %CI: 0.92–1.23 for Trp/Trp vs. Arg/Arg; OR = 0.93 with 95 %CI: 0.87–1.00 for Trp/Trp + Arg/Trp vs. Arg/Arg; and OR = 1.08 with 95 %CI: 0.94–1.25 for Trp/Trp vs. Arg/Trp + Arg/Arg]. The cumulative meta-analysis showed that the results maintained the same, while the ORs with 95 % CI were more stable with the accumulation of case-control studies. It is a valuable study. …
