摘要 目的观察胃癌及EB病毒(EBV)阳性胃癌患者Toll样受体4(TLR4)基因rs10759932、rs11536889多态性,探讨其与胃癌和EBV相关胃癌(EBVaGC)易感性的关系。方法采用PCR结合限制性片段长度多态性(RFLP)检测160例胃癌患者[胃癌组,包括41例EBVaGC患者和119例EBV阴性(EBVnGC)患者]、100例健康体检者(对照组)TLR4基因rs10759932、rs11536889位点多态性。结果 (1)TLR4基因rs10759932位点多态性:胃癌组基因型TT者90例、TC者53例、CC者7例,等位基因T频数233(77.7%)、等位基因C频数67(22.3%)。对照组基因型TT者42例、TC者40例、CC者18例,等位基因T频数124(62.0%)、等位基因C频数76(38.0%)。胃癌组TT基因型频率明显高于对照组(χ2=14.373,P<0.01)。与携带CC基因型者相比,携带TT基因型者罹患胃癌的风险增加(OR=5.510,95%CI为2.138~14.202,P<0.01)。胃癌组和对照组等位基因T、C频率比较有统计学差异(χ2=14.423,P<0.01)。个体携带等位基因C可以降低罹患胃癌的风险(OR=2.131,95%CI为1.437~3.161,P<0.01)。胃癌组EBVaGC和EBVnGC患者基因型和等位基因分布相比,P均>0.05。(2)TLR4基因rs11536889位点多态性:胃癌组和对照组、胃癌组EBVaGC和EBVnGC患者基因型和等位基因分布相比,P均>0.05。结论TLR4基因rs10759932位点多态性与胃癌易感性有关,携带C等位基因者罹患胃癌的风险较低。TLR4基因rs11536889位点多态性与胃癌易感性无关。TLR4基因rs10759932、rs11536889位点多态性与胃癌是否合并EBV感染无关。
