1、Survivin蛋白在肝門部膽管癌中的表達及其與p53相關(guān)性的研究【摘要】目的:檢測肝門部膽管癌中凋亡抑制因子Survivin蛋白的表達,研究其與肝門部膽管癌的臨床特征的關(guān)系,并探討其與p53的相關(guān)性。方法:采用免疫組織化學方法檢測86例肝門部膽管癌組織、10例癌旁組織(距腫瘤邊緣約1.0cm)及10例正常膽管組織中Survivin蛋白和p53蛋白的表達,結(jié)合臨床病理學資料進行統(tǒng)計學分析。結(jié)果:86例肝門部膽管癌組織中,Survivin蛋白陽性率為82.6%(71/86),p53蛋白陽性率為76.7%(66/86),Survi
2、vin與p53在癌旁組織和正常膽管組織中均呈陰性表達,與癌組織相比差異有統(tǒng)計學意義(P<0.05);Survivin表達與肝門部膽管癌病理分級、Bismuth分型、患者的性別及年齡和腫瘤大小均無關(guān)(P>0.05),但淋巴結(jié)轉(zhuǎn)移陽性組Survivin蛋白表達水平明顯高于淋巴結(jié)轉(zhuǎn)移陰性組,差異有統(tǒng)計學意義(P<0.05);p53蛋白在肝門部膽管癌中與腫瘤組織病理分級、淋巴結(jié)有無轉(zhuǎn)移相關(guān)(P<0.05),與其他病理學特征無關(guān)(P>0.05)。71例Survivin陽性表達者中同時表達p53陽性者58例,
3、15例陰性表達者中表達p53陽性者8例,兩者差異有統(tǒng)計學意義(P<0.05)。結(jié)論:肝門部膽管癌組織中Survivin和p53的表達顯著高于癌旁組織和正常膽管組織,其在肝門部膽管癌的發(fā)展、轉(zhuǎn)移過程中可能具有重要作用。【關(guān)鍵詞】膽管腫瘤·Survivin·蛋白質(zhì)p53·免疫組織化學ExpressionandimplicationofSurvivinanditscorrelationwithp53inhilarcholangiocarcinoma【ABSTRACT】Objective:Toinvestigatetheexpr
