目的 探討尾型同源盒轉錄因子-2 (CDX-2)和抑癌基因KAI-1在結腸癌中的表達并分析其臨床意義。
方法 應用免疫組織化學SP法檢測50例結腸癌組織及相應癌旁組織和25例正常結腸黏膜組織中CDX-2和KAI-1蛋白的表達,分析其表達與結腸癌患者臨床病理特征的關系以及二者表達的相關性。
結果 ?、僭诮Y腸癌組織及相應癌旁組織(距癌組織≤2cm)和正常結腸黏膜組織中CDX-2蛋白表達陽性率分別為34% (17/50)、54% (27/50)及88% (22/25),KAI-1蛋白表達陽性率分別為30% (15/50)、58% (29/50)及92% (23/25),CDX-2 和KAI-1在結腸癌組織中的蛋白表達陽性率均分別明顯低于相應癌旁組織(P<0.05)及正常結腸黏膜組織(P<0.05),其在癌旁組織中的表達陽性率也均明顯低于正常結腸黏膜組織(P<0.05)。②CDX-2和KAI-1蛋白表達陽性率與結腸癌淋巴結轉移、浸潤深度及分化程度均有關(P<0.05),即在有淋巴結轉移、浸潤深度浸及漿膜及分化程度較低者中CDX-2和KAI-1蛋白表達陽性率均明顯低于其在無淋巴結轉移、浸潤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(P>0.05)。③Spearman等級相關分析表明,CDX-2和KAI-1蛋白陽性表達呈正相關(rs=0.544,P<0.01)。
結論 CDX-2和KAI-1的表達可能與結腸癌的發(fā)生、發(fā)展、浸潤、轉移及預后相關,聯(lián)合評價其功能可能對結腸癌治療具有一定指導意義。
