目的  探討尾型同源盒轉(zhuǎn)錄因子-2 (CDX-2)和抑癌基因KAI-1在結(jié)腸癌中的表達(dá)并分析其臨床意義。
方法  應(yīng)用免疫組織化學(xué)SP法檢測(cè)50例結(jié)腸癌組織及相應(yīng)癌旁組織和25例正常結(jié)腸黏膜組織中CDX-2和KAI-1蛋白的表達(dá),分析其表達(dá)與結(jié)腸癌患者臨床病理特征的關(guān)系以及二者表達(dá)的相關(guān)性。
結(jié)果 ?、僭诮Y(jié)腸癌組織及相應(yīng)癌旁組織(距癌組織≤2cm)和正常結(jié)腸黏膜組織中CDX-2蛋白表達(dá)陽性率分別為34% (17/50)、54% (27/50)及88% (22/25),KAI-1蛋白表達(dá)陽性率分別為30% (15/50)、58% (29/50)及92% (23/25),CDX-2 和KAI-1在結(jié)腸癌組織中的蛋白表達(dá)陽性率均分別明顯低于相應(yīng)癌旁組織(P<0.05)及正常結(jié)腸黏膜組織(P<0.05),其在癌旁組織中的表達(dá)陽性率也均明顯低于正常結(jié)腸黏膜組織(P<0.05)。②CDX-2和KAI-1蛋白表達(dá)陽性率與結(jié)腸癌淋巴結(jié)轉(zhuǎn)移、浸潤(rùn)深度及分化程度均有關(guān)(P<0.05),即在有淋巴結(jié)轉(zhuǎn)移、浸潤(rùn)深度浸及漿膜及分化程度較低者中CDX-2和KAI-1蛋白表達(dá)陽性率均明顯低于其在無淋巴結(jié)轉(zhuǎn)移、浸潤(rùn)深度未及漿膜及分化程度較高者(P<0.05),二者均與患者的發(fā)病年齡和性別無關(guān)(P>0.05)。③Spearman等級(jí)相關(guān)分析表明,CDX-2和KAI-1蛋白陽性表達(dá)呈正相關(guān)(rs=0.544,P<0.01)。
結(jié)論  CDX-2和KAI-1的表達(dá)可能與結(jié)腸癌的發(fā)生、發(fā)展、浸潤(rùn)、轉(zhuǎn)移及預(yù)后相關(guān),聯(lián)合評(píng)價(jià)其功能可能對(duì)結(jié)腸癌治療具有一定指導(dǎo)意義。
