2、EGFR突變表達(dá)與非小細(xì)胞肺癌的病理類(lèi)型、腫瘤大小及淋巴結(jié)轉(zhuǎn)移有關(guān),但血漿EGFR突變表達(dá)與非小細(xì)胞肺癌患者的疾病進(jìn)展時(shí)間、生存時(shí)間無(wú)關(guān)。結(jié)論非小細(xì)胞肺癌患者血漿EGFR的檢測(cè)有可能替代腫瘤組織中EGFR的檢測(cè),為無(wú)法取得腫瘤組織或取得腫瘤組織困難的患者提供一種更快捷、簡(jiǎn)便的替代檢測(cè)方法,但血漿EGFR尚不能確立為獨(dú)立的預(yù)后指標(biāo)。[關(guān)鍵詞]非小細(xì)胞肺癌;血漿;表皮生長(zhǎng)因子受體;熒光定量PCR;預(yù)后DOI:10.3969/j.issn.1673—5412.2015.03.003[中圖分類(lèi)號(hào)]R734.2[文獻(xiàn)標(biāo)識(shí)碼]A[文章編號(hào)]1673—5412(2015)03—0190—
