目的 探討VEGF 和c-myc在膽管癌組織中的表達和二者之間的相關(guān)性及其在膽管癌發(fā)生、發(fā)展和轉(zhuǎn)移中的作用。
方法 應(yīng)用免疫組化ABC法對38例膽管癌組織和20例正常膽管組織中VEGF 和c-myc的表達進行檢測。
結(jié)果 VEGF 和c-myc在膽管癌組織中的表達陽性率分別為84.2%(32/38)和65.8%(25/38),明顯高于正常膽管組織中的表達陽性率〔50.0%(10/20)和20.0%(4/20)〕,差異有統(tǒng)計學(xué)意義(P<0.05); VEGF與c-myc的表達呈正相關(guān)(r=0.99, P<0.01),二者的協(xié)同表達與膽管癌的淋巴結(jié)轉(zhuǎn)移有關(guān),而與腫瘤的分級無關(guān)。
結(jié)論 VEGF可能在膽管癌形成、發(fā)展和轉(zhuǎn)移中與c-myc基因有協(xié)同作用,且與膽管癌的淋巴結(jié)轉(zhuǎn)移有關(guān)。
