目的  探討β-catenin(連環(huán)素)在胰腺癌表達(dá)的臨床意義。
方法  對(duì)手術(shù)切除的46例胰腺癌標(biāo)本進(jìn)行免疫組化染色,檢測(cè)β-catenin在胰腺癌中的表達(dá),并分析其和胰腺癌的分級(jí)、分期以及有無轉(zhuǎn)移等指標(biāo)的關(guān)系。
結(jié)果  β-catenin在胰腺癌細(xì)胞膜的異常表達(dá)率為54.3%,且分化越差則在細(xì)胞膜的異常表達(dá)率越高,有轉(zhuǎn)移者高于無轉(zhuǎn)移者; 其在細(xì)胞漿的異常表達(dá)率為21.7%,與胰腺癌的分化、分期及有無轉(zhuǎn)移無顯著相關(guān)性,但23例術(shù)前介入化療的患者中,腫塊縮小者(14例)在細(xì)胞漿的異常表達(dá)率為0,顯著低于9例腫塊無縮小者的33.3%; β-catenin在細(xì)胞膜和細(xì)胞漿異常表達(dá)具有一致性,為63.0%。
結(jié)論  β-catenin在細(xì)胞膜的異常表達(dá)能促進(jìn)腫瘤轉(zhuǎn)移,在細(xì)胞漿內(nèi)的異常表達(dá)可能會(huì)促進(jìn)腫瘤細(xì)胞的增殖。
