摘要 目的:研究中国汉族人DICER基因rs3742330A〉G多态性与食管癌易感性的关系。方法:本研究以病例一对照研究为基础,收集2008—10—01—20091130镇江第一人民医院和江苏大学附属人民医院380例食管癌患者和380例非肿瘤患者,采用质谱(MALDI—TOFMS)技术对DICER基因多态性位点rs3742330A〉G进行分型,计算不同基因型与食管癌的发生风险及95%CI。结果:DICER多态性位点rs3742330A〉G基因型AA、AG和GG在食管癌组频率分别为33.9%、51.6%和14.5%,在非肿瘤对照组的频率分别为38.1%、48.4%和13.5%。Logistic回归分析结果表明,相对于AA基因型的个体,AG基因型与食管癌的发病风险无明显相关,OR=1.19,95%CI=0.87~1.62;与AA+AG基因型相比较,GG基因型与食管癌的发病风险无明显相关,OR=1.09,95%CI=0.72~1.65。结论:DICER基因rs3742330A〉G多态性可能不是食管癌发生的危险因素。 OBJECTIVE:To evaluate the relationship between DICER polymorphism and esophageal cancer risk in a Chinese Han population. METHODS: Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MAL- DI-TOF MS) methods were used to determine DICER rs3742330 A〉G genotypes in 380 esophageal cancer patients and 380 controls. RESULTS: The DICER rs3742330 A〉G genotype frequencies were 33.9% (AA), 51. 6% (AG), 14. 5% (GG) in esophageal cancer group and 38.1% (AA) ,48.4% (AG) ,13.5% (GG) in the control group respectively. Logistic regression analyses revealed that the risk associated with DICER rs3742330 genotype was 1.19 (95%CI:0. 87-1. 62) for DICER rs3742330 AG compared with DICER rs3742330 AA genotype. Compared with AAq-AG genotype, the risk associated with GG genotype was 1.09 (95%CI= 0. 72-1. 65). CONCLUSION: DICER rs3742330 A〉G polymorphism may not be associated with esophageal cancer risk.
