1、MAGE—A3在非小细胞肺癌中的表达及对预后影响的研究摘要目的:旨在探讨MAGE—A3在jllEd,细胞肺癌(NSCLC)中的表达及与肺癌转移和预后的关系。方法:采用免疫组织化学方法检测74例ql!d,细胞肺癌和15例癌旁组织中MAGE—A3的表达。结果:MAGE—A3在NSCLC组织中阳性率为48.6o/60,高于癌旁肺组织阳性率6.7%,差异有统计学意义(P2、与患者年龄、性别、淋巴结状况、肿瘤细胞的分化程度、临床分期均无相关性(P>O.05)。肺腺癌中MAGE—A3表达阳性组复发转移率高于阴性组。MAGE—A3表达阴性组NSCLC患者5年生存率为59.3%(19/32),表达阳性组患者5年生存率为33.3%(12/36),两组问比较有显著性差异(x2=4.632P=O.031)。..结论:MAGE-A3在NSCLC组织中阳性率显著高于癌旁组织。MAGE-A3在肺腺癌中的表达水平显著高于肺鳞癌。分层分析显示腺癌中MAGE-A3F[J性表达与复发、转移有关。MAGE—A3检测可作为非小细胞肺癌预后不良的检测指标。硕士研究生董艳(免3、疫学)指导教师高美华教授关键词:非小细胞肺癌;黑素瘤抗原-A3;免疫组化;预后AStudyontheRelationshipbetweenExpressionofMAGE—A3andMetastasisandPrognosisinPatientswithNon—smallCellLungObjective:CancerAbstractTostudytherelationshipbetweenexpressionofMAGE—A3andprognosis,prognosisinpatientswithnon—smalllungcancer.Methods:Theexpres4、sionofMAGE·-A3isdetectedin74non--smallcelllungcancertissuesand15adjacentnon—cancerouslungtissuesbyimmunohistochemistrymethod.Results:TheexpressionofMAGE—A3inlungcancertissueswassignificantlyhigherthanthatinadjacentnon—cancerouslungtissues(P<0.05).TheexpressionofMAGE—A3inadenocarcinomawass5、ignificantyhigherthanofthatinsqumascellcarcinomas(P<0.05).Thedisease—freerates(DFS)waslowerinpatientswithMAGE—A3expressthaninnotexpressgroup(P>0.05)),furtherstratifiedanalyticindicatedthatinadenocarcinomagroupwassignificantlybetweenthedifferentexpressionofMAGE—A3;Theresultsofmultivariable6、Coxmodelanalysisshowedm哪l洲4叭●●删9Ⅲ3咖3洲2ⅢYthatdetectionoftheexpressionofMAGE-.A3mightbehelpfulforpredictingprognosisofpatientswithlungcancer,.CondusiLon-TheexpressionofMAGE—A3inlungcancertissuesis48.6%inNSCLC,theseresultsindicatetheexpressionofMAGE—A3innon—smallcelllungcancerwassignificantl7、yhigherthenormaltissues.MAGE—A3expressionintheadenocarcinomawassignificantlyhigherthaninthesquamouscellcarcinoma(PO.05).NoassociationwasobservedforMAGE—A3expressionandtheag
