1、上皮性卵巢癌患者外周血中R跚2的表达及临床意义摘要目的探讨核苷酸还原酶小亚基M2(RRM2)在卵巢癌患者外周血中的检测情况并初步探讨其作为肿瘤标志物对上皮性卵巢癌诊断的意义。方法采用实时荧光定量逆转录聚合酶链反应(real.timeRT-PCR)检测70例上皮性卵巢癌患者、16例低度潜在卵巢恶性肿瘤、15例卵巢良性肿瘤患者和15例正常人外周血标本单个核细胞中的RRM2的相对表达量,并将检测结果与临床病理参数进行统计学分析。结果1.上皮性卵巢癌患者外周血中RRM2mRNA的表达量(2.541+0.801)和低度潜在恶性肿瘤(2.180-J:0.392)显著高
2、于良性卵巢肿瘤患者(1.641+0.377)和正常人(1.388+0.222)(P<0.05),后两者间表达无差异(P>O.05)。2.RRM2mRNA表达随临床分期的进展呈上升趋势(PO.05)。3.上皮性卵巢癌患者外周血中RRM2mRNA的表达与血清中CAl25、HE4表达呈正相关(P3、67.4%,特异性和83.3%),ROC曲线下面积0.801(95%C10.712-0.872,P=0.000)。结论1.RRM2可能在上皮性卵巢癌的发生发展中发挥癌基因的作用,有望成为诊断上皮性卵巢癌的新指标。2.RRM2mRNA与CAl25、HE4联合检测时,兼顾了敏感性和特异性,与单项指标诊断相比,可提高对上皮性卵巢癌的诊断能力。硕士研究生王菲(妇产科学)指导老师王黎明副教授关键词:RRM2;卵巢肿瘤;实时荧光定量聚合酶链反应;诊断ExpressionofRRM2inperipheralbloodofPatientswithOvarianEpithe4、lialCarcinomaandItsClinicalSignifiObjective:ToinvestigatethedetectionofRibonucleotideReductaseM2(RRM2)inepithelialovariancancersamplesandtoinvestigatethepossibilityofRRM2inperipheralbloodusedasbiomarkerforepithelialovariancancer.Method:TheexpressionofRRM2inperipheralbloodfrom70cas5、esofepithelialovariancancerand16casesofborderlineovarianneoplasmand15casesofbenignepithelialovariantumorand15casesofnormalpersonsWasdetectedbyreal--timeRT·-PCRandstatisticallyanalyzetherelevancebetweentheexpressionofRRM2mRNAinperipheralbloodandtheclinicopathologicalparameters.Resu6、lt:1.TheexpressionofRRM2mRNAinepithelialovariancancerperipheralblood(2.541士0.801)andborderlineovarianneoplasm(2.180-xO.392)Wassignificantlyhigherthanthoseinbenignepithelialovariantumor(1.641士0.377)andnormalpersons(1.388士0.222)(P<0.05),butthereWasnodifferencebetweenthelattertwogrou7、ps.2.TheexpressionofRRM2mRNAincreasedwiththeprogressionoftheclinicalstage(P8、tologicaltypesinepithelialovarian
