1、子宫内膜癌组织中微血管密度表达的临床研究【关键词】子宫内膜癌摘要:目的测定子宫内膜癌组织中微血管密度(MVD)表达情况,探讨MVD与子宫内膜癌的临床病理特征、转移、预后的关系。方法选取47例子宫内膜癌标木,采用免疫组织化学技术利用Vffl因子相关抗原标记癌组织中的血管内皮细胞,高倍镜下计数为MVD。与20例正常子宫内膜标本进行对照。结果①子宫内膜癌组织的MVD值均高于正常子宫内膜(P〈0.01),且绝经后内膜癌患者的MVD高于绝经前患者(P〈0.05)。②MVD与子宫内膜癌患者的年龄、组织学分级、FIGO分期、了宫肌层浸润深度及淋巴结转移相关(P〈0.01、P〈0.05)。③FI-GO分
2、期越晚,MVD越呈高密度表达趋势,两者之间有相关性(P3、2,China)Abstract:ObjectiveMicrovesseldensity(MVD)wasstudiedtodecipheritsvalueintheclinicalpathology,metastasisandprognosisofendometrialcarcinoma・MethodsMicroscopicsectionsfrom47specimensofendometrialcarcinomawerescannedatlowmagnificationtoidentifyareasoftopcapillarydensity,andtheparallelsectionsw4、erethenstainedimmunohisto-chemicallywithamarkerforendothelialcellstodeterminethemicrovasculardensity(MVD)intermsofthenumberofvesselsperhigh-powermicroscopicfield.Twentysamplesofnormalendometriumwereusedforcontro1.Results①TheMVDinen-dometrialcarcinomawashigherthaninnormalendometria(P<0.01),andwash5、igheraftermenopausethanbeforemenopause(P<0.05)・②MVDofendometrialcarcinomawassignificantlycorrelatedwithage,tumorgrade,surgicalstage,myometrialinvasionand1ymphnodematastasis(P<0.01,P<0.05)•③AsMVDwassignificantlycorrelatedwithsurgicalstage(P<0.01),higherlevelofMVDtendedtoberelatedtopoorprognosis(P〈6、0・05)・ConclusionMVDiscorrelatedwithtumormalignancy,infiltrationandmetastasis,andcanbeusedasanimportantprognosticatorofendometrialcarcinoma・Keywords:endometrialcancer;angiogenesis;microvesseldensityjclinicalpathology;prognosis;immunohistochemistry子宫内膜癌是原发于子宫内膜上皮的恶性肿瘤,近年来发病率有上升趋势,早期内膜癌的治愈率较高,而伴发转移的7、患者预后极差。由于取材不方便或易误诊为月经不调,子宫内膜癌的早期诊断率往往低于宫颈癌,因此有关了宫内膜癌转移及患者预后的研究依然是内膜癌基础临床研究的重要内容。实体肿瘤的生长和代谢需要持续的血管生长以维持营养供应,血管生成是肿瘤恶性转化、生长和转移的生物学基础与重要环节。将子宫内膜癌接种到鸡绒毛膜丿求囊或兔角膜时会诱导血管生成,应用血管介入技术在子宫切除标木中发现内膜癌周围有混乱丰富的血管,均说明子宫内膜癌具有血管生成活性。AWei
