目的　探討中國胰腺癌患者Ki-ras基因第12密碼子突變表型的特點(diǎn)及與西方國家胰腺癌的區(qū)別。方法　采用PCR擴(kuò)增靶基因片段，Dot blot雜交的方法檢測59例中國胰腺癌患者標(biāo)本中Ki-ras基因第12密碼子突變表型。利用Medline檢索相關(guān)西方國家文獻(xiàn)報道的胰腺癌患者Ki-ras基因第12密碼子突變表型，并與本組資料進(jìn)行對比。結(jié)果　本組患者Ki-ras基因第12密碼子突變頻繁（76.3%）。與西方國家文獻(xiàn)報道的資料比較顯示，各國胰腺癌患者中Ki-ras基因第12密碼子突變頻率差異無統(tǒng)計學(xué)意義（P＞0.05），但突變的表型及第二堿基突變的轉(zhuǎn)換和顛換比的差異存在統(tǒng)計學(xué)意義（P＜0.05，P＜0.01，P＜0.001）。結(jié)論　Ki-ras基因第12密碼子突變在中國胰腺癌患者較頻繁，其突變表型在各國胰腺癌患者中可能存在差異。
