Association of XRCC3 gene rs861539 polymorphism with gastric cancer risk: evidence from a case-control study and a meta-analysis.

ABSTRACT: The association between the X-ray repair cross-complementing group 3 (XRCC3) gene Thr241Met polymorphism (rs861539) and gastric cancer has been widely evaluated, but a definitive answer is so far lacking. We first conducted a case-control study to assess this association in a large Han Chinese population, and then performed a meta-analysis to further address this issue. Although our case-control association study and the following meta analysis involving 6,520 subjects indicated null association of XRCC3 gene rs861539 polymorphism between gastric cancer patients and controls under both allelic (odds ratio (OR) = 1.02; 95% confidence interval (CI): 0.91-1.14; P = 0.739) and dominant (OR = 0.97; 95% CI: 0.78-1.21; P = 0.803) models. Stratified analysis by ethnicity demonstrated a significant
