2、性。方法:選取本院收治的60例原發(fā)性肝細(xì)胞癌患者,應(yīng)用免疫組織化學(xué)染色的方法對肝癌組織及癌旁組織中的XIAP及survivin的表達(dá)進(jìn)行檢測。結(jié)果:經(jīng)比較,肝癌組織中XAIP及survivin的陽性率均顯著高于癌旁組織,差異有統(tǒng)計(jì)學(xué)意義。XIAP和survivin的表達(dá)強(qiáng)度與腫瘤的大小無關(guān),但隨腫瘤的分化程度的降低而升高,且不同分化程度之間差異有統(tǒng)計(jì)學(xué)意義;XIAP和survivin存在正相關(guān)關(guān)系。結(jié)論:XIAP與Survivin在腫瘤組織中的高表達(dá)在促進(jìn)腫瘤發(fā)生、增殖、轉(zhuǎn)移以及耐藥,并且能夠降低腫瘤的分化程度,
3、增加肝癌的惡性程度。此外,兩者可能存在協(xié)同作用,但兩者的相關(guān)性及作用機(jī)制仍需進(jìn)一步探討。關(guān)鍵詞:原發(fā)性肝細(xì)胞癌;x連鎖凋亡抑制蛋白;survivin;相關(guān)性中圖分類號:R735.7;R365文獻(xiàn)標(biāo)識碼:A文章編號:1673-6273(2014)18-3426—03StudVontheExpressionandCrrelationOfXIAPandSurvivininPrimaryHepatocellularCarcinoma(HCC、)冰YANGDe-hu#,GUOXiao-dong~,YULing-Mange,
