1、Ecadherin和Ki67在結(jié)直腸癌組織中的表達(dá)及意義 ; ; ; ; ; ; ; ; ;作者:何艷姣,劉朝霞,李洪利,俞進(jìn),李光【摘要】 ;目的探討Ecadherin和Ki67在結(jié)直腸癌中的表達(dá)及意義。方法應(yīng)用免疫組化SP法檢測48例結(jié)直腸癌、23例結(jié)腸腺瘤和20例正常結(jié)腸組織中Ecadherin及Ki67的表達(dá),并分析其與結(jié)直腸癌臨床病理特征的關(guān)系。結(jié)果結(jié)直腸癌、結(jié)腸腺瘤和正常結(jié)腸組織中Ecadherin異常表達(dá)率分別為77.1%、24.0%和5.0%,結(jié)直腸
2、癌Ecadherin異常表達(dá)率明顯高于結(jié)腸腺瘤和正常結(jié)腸組織,組間比較差異有顯著性(PV0.01)。Ki67陽性指數(shù)在結(jié)直腸癌、結(jié)腸腺瘤及正常結(jié)腸組織中分別為(67.60土2.52)%、(38.44±3,59)%及(8.65±1,10)%。結(jié)直腸癌的Ki67陽性指數(shù)明顯高于結(jié)腸腺瘤和正常結(jié)腸組織,組間兩兩比較差異有統(tǒng)計學(xué)意義(P<0.01)。Ecadherin表達(dá)與浸潤深度和有無淋巴轉(zhuǎn)移有關(guān)(P=0.020和P=0.013),而與患者的年齡、性別、大體形態(tài)、分化程度無關(guān)。Ki67表達(dá)與患者性別和有無淋巴轉(zhuǎn)移有關(guān)(P=0.011和P=0.043)
3、,而與患者的年齡、大體形態(tài)、分化程度、浸潤深度無關(guān)。Ecadherin正常表達(dá)組和異常表達(dá)組的Ki67陽性指數(shù)分別為(67.30±18.87)%和(68.64±11.99)%。Ecadherin異常表達(dá)組Ki67陽性指數(shù)略高于正常表達(dá)組,但無統(tǒng)計學(xué)意義。結(jié)論Ecadherin和Ki67是結(jié)直腸癌發(fā)生發(fā)展過程中的重要因子,并與結(jié)直腸癌浸潤轉(zhuǎn)移有關(guān),可作為評估結(jié)直腸癌預(yù)后、指導(dǎo)治療的指標(biāo),但兩者在結(jié)直腸癌發(fā)生、發(fā)展、侵襲和轉(zhuǎn)移過程中沒有協(xié)同作用?!娟P(guān)鍵詞】 ;結(jié)直腸腫瘤;Ecadherin;Ki67ExpressionandSignific
