Here we focused on one XRCC3 polymorphism anddevelopment of cervical cancer, performing a meta-analysis. Methods: The pooled association between theXRCC3 Thr241Met polymorphism and cervical cancer risk was assessed by odds ratios (ORs) and their 95%confidence intervals (95%CIs). Results: A total of 5 case-control studies met the inclusion criteria. The pooledORs for the total included studies showed no association among homozygotes TT vs. CC: OR=1.93, 95%CI=0.68-5.49, P=0.22; dominant model TT+TC vs. CC: OR=1.37, 95%CI=0.90-2.06, P=0.14; and recessive model TT vs.TC+CC: OR=1.76, 95%CI=0.68-4.55, P=0.25, but might be a slight risk factor for cervical cancer in heterozygotecontrast TT vs. CT: OR= 1.33, 95%CI=1.04-1.71, P=0.02. In subgroup analysis, significant associations werefound for Asians under all genetic models. Conclusions: Our meta-analysis suggested the XRCC3 Thr241Metpolymorphism might not act as a cervical cancer risk factor overall. However, in subgroup analysis, a significantassociation was found in Asians under all genetic models. The association should be studied with a larger, stratifiedpopulation, especially for Asians.
