摘  要:目的探讨白细胞介素-28B(IL-28B)基因不同位点SNP与原发性肝细胞肝癌的关系。方法以2001年i1月至2010年4月就诊于桂林某医院和北京某医院的肝癌患者作为病例组,共300例,其中有139例患者具有完整的临床追踪资料;选取2009--2010年于上述两所医院中进行健康体检,且无肿瘤及慢性乙型肝炎疾病史者作为对照组,共310名;研究对象均为汉族,无年龄、性别限制。经知情同意,每名研究对象采集外周血2ml,采用质谱分析法对研究对象IL-28B基因rs12972991、rs8099917、rs12979860和rs4803223等位点SNP进行分析。结果病例组rs12972991位点c等位基因、rs8099917位点G等位基因和rs4803223位点G等位基因频率分别是6.7%(40/598)、7.9%(47/598)、10.0%(59/588);对照组分别为2.9%(18/618)、4.1%(25/616)、3.6%(21/608),病例组均高于对照组,差异有统计学意义(X2值分别为9.542、7.858、20.736,P值均〈0.05);携带上述等位基因可增加原发性肝细胞肝癌的患病风险[OR(95%CI)值分别为1.67(1.13~2.46)、1.49(1.08~2.06)、2.91(1.79~4.72)]。病例组rs12972991位点AC+CC基因型、rs8099917位点GT+GG基因型和rs4803223位点GA+GG基因型频率分别为13.0%(39/299)、14.7%(44/299)、19.0%(56/296);对照组分别为5.8%(18/309)、8.1%(25/308)、6,6%(20/304),病例组均高于对照组,差异有统计学意义(X2值分别为9.319、6.557、20.948,P值均〈0.05);携带上述基因型可增加原发性肝细胞肝癌的患病风险[OR(95%C/)值分别为2.24(1.31—3.83)、1.81(1.14~2.88)、2.90(1.78~4.70)]。对患者临床资料分析发现,出现门静脉癌栓的患者rs4803223位点GA+GG基因型频率为50.0%(13/26),高于AA基因型频率[21.1%(23/109)]�Objective To explore the correlation between single nucleotide polymorphisms (SNPs) of interleukin-28B (IL-28B) gene and the susceptibility to primary hepatocellular carcinoma (HCC). Methods A total of 300 histologically confirmed HCC cases (from November 2001 to April 2010) and 310 healthy controls with no history of chronic hepatitis B or hepatocellular carcinoma (2009 - 2010) were selected from a hospital in Guilin and a hospital in Beijing for this case-control study. 139 HCC patients in the case group had complete clinical tracking data. All the subjects were Han Chinese, with no age or gender restrictions. 2 ml peripheral blood samples were drawn from each subject with informed consent. SNP of rs12972991, rs4803223, rs8099917 and rs12979860 four loci in IL-28B gene were analyzed by matrix-assisted laser desorption/ionization time of flight mass spectrometry (MALDI-TOF). Results The frequencies of C allele at rs12972991, G allele at rs8099917 and G allele at rs5803223 were 6. 7% (40/ 598), 7.9% (47/598) and 10.0% (59/588) respectively in case group; all higher than the corresponding frequencies in control group, separately 2. 9% ( 18/618), 4. 1% (25/616) and 3.6% (21/608). The differences were statistically significant ( x2 = 9. 542, 7. 858, 20. 736, P values all 〈 0. 05 ). The above alleles could increase the risk of HCC, and the OR(95% CI) values were separately 1.67 (1.13 -2. 46), 1.49( 1.08 -2. 06) and 2. 91 ( 1.79 -4. 72). The genotype frequencies of AC + CC at rs12972991, GT + GG at rs8099917, GA + GG at rs4803223 were 13.0% (39/299), 14. 7% (44/299) and 19.0% (56/296) respectively in ease group; while the frequencies were lower in control group, separately 5.8% (18/309) , 8. 1% (25/308) and 6. 6% (20/304). The differences were statistieally significant ( X2 = 9.319, 6. 557, 20. 948, P values all 〈 0.05 ) . These genotypes may increase the risk of HCC, and the adjusted OR (95%C1) values were 2.
