目的探討p16、Rb基因在原發(fā)性膽囊癌中的表達(dá)及其與病理生物學(xué)行為和預(yù)后的關(guān)系。方法采用免疫組化（SP）法對(duì)56例膽囊癌進(jìn)行p16和Rb蛋白的定位觀察。結(jié)果p16和Rb基因在原發(fā)性膽囊癌中的表達(dá)陽性率分別為46.3%和71.4%,顯著低于在膽囊良性病變中的表達(dá)（P＜0.05）。Rb表達(dá)與膽囊癌的病理組織學(xué)分級(jí)、組織類型、浸潤、轉(zhuǎn)移和預(yù)后無明顯關(guān)系(P gt;0.05)； 而p16與膽囊癌的浸潤、轉(zhuǎn)移和預(yù)后有明顯相關(guān)性（P＜0.05）。p16和Rb基因蛋白表達(dá)存在著明顯的互補(bǔ)性。結(jié)論p16和Rb基因蛋白丟失是膽囊癌發(fā)生、發(fā)展中的重要分子事件，與細(xì)胞周期G1S期的負(fù)反饋調(diào)節(jié)環(huán)路中斷關(guān)系密切。p16蛋白表達(dá)可作為評(píng)估膽囊癌病理生物學(xué)行為及預(yù)后的參考指標(biāo)。
