Abstract

<abstract abstract-type="main"> <title>Abstract</title> <sec id="jphp12264-sec-0001" sec-type="section"> <title>Objectives</title> <p>Gastric cancer is one of the most frequently causing cancer‐related deaths worldwide. The X‐ray repair complementing group 1 gene (<italic>XRCC1</italic>) is an important candidate gene for influencing gastric cancer risk. This study aimed to evaluate the associations between <italic>XRCC1</italic> genetic variants and gastric cancer susceptibility in Chinese Han population.</p> </sec> <sec id="jphp12264-sec-0002" sec-type="section"> <title>Methods</title> <p>Four hundred twenty‐four gastric cancer patients and 430 cancer‐free controls were enrolled. Two genetic variants (c.1254C>T and c.1779C>G) of <italic>XRCC1</italic> gene were genotyped by created restriction site‐polymerase chain reaction (PCR) and PCR‐restriction fragment length polymorphism methods, respectively.</p> </sec> <sec id="jphp12264-sec-0003" sec-type="section"> <title>Key findings</title> <p>Results from this study indicated that the allele and genotype frequencies of these two genetic variants were statistically different between gastric cancer patients and cancer‐free controls. The association analyses suggested that these two genetic variants were statistically associated with the increased risk of gastric cancer (for c.1254C>T, T versus C: odds ratio (OR) = 1.44, 95% confidence interval (CI) 1.17–1.77; for c.1779C>G, G versus C: OR = 1.51, 95% CI 1.22–1.86). The allele‐T of c.1254C>T and allele‐G c.1779C>G genetic variants may contribute to the susceptibility to gastric cancer in Chinese Han population.</p> </sec> <sec id="jphp12264-sec-0004" sec-type="section"> <title>Conclusion</title> <p>Our data suggest that these two genetic variants might be used as molecular markers for evaluating the susceptibility to gastric cancer.</p> </sec> </abstract>
