摘要: 目的:探讨DNA修复基因ERCC4、ERCC5多态性与唾液腺肿瘤发病风险的关系。方法:采用病例-对照研究方法,应用聚合酶链反应-限制性片段长度多态性(PCR-RFLP)技术对133例经组织学确诊的唾液腺肿瘤病例和142例按年龄、性别匹配的健康对照组的ERCC4 rs6498486与ERCC5 rs751402 2个多态基因型进行检测,应用SPSS 18.0软件包中的多因素Logistic回归分析进行基因多态性与唾液腺肿瘤发病风险关系评估。结果:与(CC+CT)型相比,ERCC5 rs751402多态纯合TT型携带者唾液腺肿瘤发病风险降低(OR=0.45,95% CI:0.21,0.98),差异具有显著性(P<0.05)。唾液腺肿瘤病例组与对照组间ERCC4 rs6498486多态基因型频率分布无显著差异(P>0.05)。结论:携带ERCC5 rs751402多态TT型个体唾液腺肿瘤的发病风险可能降低。

Abstract: PURPOSE: To investigate the association between ERCC4 and ERCC5 polymorphisms and risk of salivary gland tumors. METHODS: Case-control study was carried out in 133 cases of histologically confirmed salivary gland tumors and 142 age and gender matched healthy control cases. Polymorphisms of ERCC4 rs6498486 and ERCC5 rs751402 were detected by PCR-RFLP. Multiple factors logistic regression analysis was conducted to investigate the association between gene polymorphisms and risk of salivary gland tumors using SPSS 18.0 software package. RESULTS: The genotype distribution of each polymorphism was found to be of Hardy-Weinberg equilibrium in the study. ERCC5 rs751402 TT genotype was associated with risk of salivary gland tumors (TT vs. CC+CT: OR=0.45, 95% CI: 0.21-0.98, P=0.046). No significant association was found in ERCC4 rs6498486. CONCLUSIONS: The results suggest that ERCC5 rs751402 polymorphism may be associated with risk of salivary gland tumors.
