Method: A total of 225 Chinese Han patients with CRC were selected as the study group, and 200 healthy subjects were recruited as the control group. The polymorphisms of XPD G751A, hOGG1 C326G and XRCC4 G1394T loci were detected by the RFLP-PCR technique in the peripheral blood of all subjects. Results: Compared with individuals carrying the XPD751 GG allele, the A allele carriers (GA\/AA) had a significantly increased risk of CRC (adjusted OR = 2.109, 95%CI = 1.352\u20133.287, P=0.003). Similarly, the G allele (CG\/GG) of hOGG1 C326G locus conferred increased susceptibility to CRC (adjusted OR = 2.654, 95%CI = 1.915\u20133.685, P&amp;lt;0.001). In addition, the T allele carriers (GT\/TT) of the XRCC4 G1394T locus have an increased risk of developing CRC (adjusted OR = 4.512, 95%CI = 2.785\u20137.402, P&amp;lt;0.001). The risk of CRC was significantly increased in individuals with both the XPD locus A allele and the hOGG1 locus G allele (adjusted OR = 1.543, 95%CI = 1.302\u20132.542, P=0.002). Furthermore, individuals with both the hOGG1 locus G allele and the XRCC4 locus T allele were predisposed to CRC development (adjusted OR = 3.854, 95%CI = 1.924\u20137.123, P&amp;lt;0.001). The risks of CRC in XPD gene A allele carriers (GA\/AA) (adjusted OR = 1.570, 95%CI = 1.201\u20131.976, P=0.001), hOGG1 gene G allele carriers (CG\/GG) (adjusted OR = 3.031, 95%CI = 2.184\u20134.225, P&amp;lt;0.001) and XRCC4 gene T allele carriers (GT\/TT) (adjusted OR = 2.793, 95%CI = 2.235\u20133.222, P&amp;lt;0.001) were significantly higher in patients who smoked \u226516 packs\/year. Conclusion: Our results suggest that XPD G751A, hOGG1 C326G and XRCC4 G1394T gene polymorphisms might play an important role in colorectal carcinogenesis and increase the risk of developing CRC in the Chinese Han population. The interaction between smoking and these gene polymorphisms would increase the risk of CRC.<\/jats:p>","DOI":"10.1042\/bsr20181074","type":"journal-article","created":{"date-parts":[[2018,11,14]],"date-time":"2018-11-14T12:14:29Z","timestamp":1542197669000},"update-policy":"https:\/\/doi.org\/10.1042\/crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Impact of polymorphisms in DNA repair genes XPD, hOGG1 and XRCC4 on colorectal cancer risk in a Chinese Han Population"],"prefix":"10.1042","volume":"39","author":[{"given":"Dexi","family":"Jin","sequence":"first","affiliation":[{"name":"Department of Gastrointestinal Surgery, the Affiliated Wenling Hospital of Wenzhou Medical University, the First People\u2019s Hospital of Wenling, Zhejiang, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Min","family":"Zhang","sequence":"additional","affiliation":[{"name":"Department of Gastroenterology, Shanxian Dongda Hospital, Shandong, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6160-5754","authenticated-orcid":false,"given":"Hongjun","family":"Hua","sequence":"additional","affiliation":[{"name":"Department of Gastroenterology, Jinhua Central Hospital, Jinhua Hospital of Zhejiang University, Zhejiang, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"288","published-online":{"date-parts":[[2019,1,15]]},"reference":[{"key":"2021111617014991400_B1","doi-asserted-by":"publisher","first-page":"177","DOI":"10.3322\/caac.21395","article-title":"Colorectal cancer statistics, 2017","volume":"67","author":"Siegel","year":"2017","journal-title":"CA Cancer J.
