1、中國肺癌雜志2009年7月第12卷第7期ChinJLungCancer,July2009,Vol.12,No.7·785··臨床經驗·肝素酶及Ki-67在非小細胞肺癌中的表達及臨床意義宋作慶徐蕭洪韋森陳軍劉懿李昕趙洪林邱小明周乃康【摘要】背景與目的已有的研究表明,肝素酶與Ki-67抗原與肺癌的發(fā)生和轉移有關,本研究通過檢測非小細胞肺癌(Non-smallcelllungcancer,NSCLC)組織中肝素酶(heparanase,Hpa)和Ki-67的表達,以探討他們的臨床意義及相互關系。方法采用
2、免疫組化方法(S-ABC法和S-P法)檢測70例NSCLC和20例同期良性病變肺組織中肝素酶和Ki-67的表達。結果肝素酶和Ki-67的陽性表達率分別為72.9%和85.7%,而正常肺組織中兩者均無表達;肝素酶表達水平與患者TNM分期及淋巴結轉移有關(P=0.044,P=0.001);Ki-67的表達水平與原發(fā)腫瘤大小、組織學類型、癌細胞分化程度、淋巴結轉移及TNM分期有關(P<0.05);肝素酶和Ki-67的表達差異無統計學意義(P=0.323)。結論肝素酶和Ki-67參與了肺癌的發(fā)生和發(fā)展,并
3、與預后相關;而肝素酶和Ki-67的表達無相關性,兩者可能通過不同的機制參與了腫瘤的發(fā)生和發(fā)展。【關鍵詞】肺腫瘤;肝素酶;Ki-67;免疫組化【中圖分類號】R734.2DOI:10.3779/j.issn.1009-3419.2009.07.008ExpressionandClinicalSignificanceofHeparanaseandKi-67inNon-smallCellLungCancer121111113ZuoqingSONG,XiaohongXU,SenWEI,JunCHEN,YiL
