目的 檢測(cè)TGF-β1及p27在原發(fā)性膽囊癌中的表達(dá),研究其蛋白產(chǎn)物在原發(fā)性膽囊癌發(fā)生、發(fā)展過程中的表達(dá)特點(diǎn)及相互關(guān)系。
方法 應(yīng)用免疫組化SP法檢測(cè)36例原發(fā)性膽囊癌中TGF-β1及p27的表達(dá),并以同期20例慢性膽囊炎作對(duì)照。
結(jié)果 36例原發(fā)性膽囊癌組織中23例TGF-β1基因蛋白產(chǎn)物呈陽性表達(dá),表達(dá)陽性率為63.9%,高于對(duì)照組的10.0%(P<0.05); 17例p27蛋白陽性表達(dá),表達(dá)陽性率為47.2%,顯著低于對(duì)照組的100%(P<0.05)。TGF-β1在有淋巴結(jié)或遠(yuǎn)處轉(zhuǎn)移及Nevin Ⅳ~Ⅴ期患者中表達(dá)陽性率(均為79.1%)明顯高于無轉(zhuǎn)移及Nevin Ⅰ~Ⅲ期的患者(均為33.3%),P<0.05; p27在高、中分化、無淋巴結(jié)或遠(yuǎn)處轉(zhuǎn)移及Nevin Ⅰ~Ⅲ期的患者中表達(dá)陽性率分別為60.9%、75.0%及75.0%,明顯高于低分化、有轉(zhuǎn)移及Nevin Ⅳ~Ⅴ期患者(23.0%、33.3%及33.3%),P<0.05。 p27與TGF-β1表達(dá)兩者呈負(fù)相關(guān)(r=-0.447 3,P<0.05)。 TGF-β1陽性患者生存率低于TGF-β1陰性患者,差異有顯著性意義(P<0.05); p27陽性患者生存率高于p27陰性患者,差異有顯著性意義(P<0.05)。
結(jié)論 在原發(fā)性膽囊癌細(xì)胞中TGF-β1表達(dá)上調(diào),p27表達(dá)下調(diào),且在有淋巴結(jié)或遠(yuǎn)處轉(zhuǎn)移及Nevin Ⅳ~Ⅴ期患者中更為明顯。
