目的  探討新疆地區(qū)維吾爾族和漢族直腸癌患者K-ras基因外顯子2中第12、13位密碼子的突變情況,為新疆地區(qū)直腸癌患者的臨床及基因診斷提供理論參考。
方法  收集2010年1月至2011年12月期間在新疆維吾爾自治區(qū)人民醫(yī)院手術(shù)切除的臨床資料完整的直腸腺癌石蠟包埋組織144例,同時(shí)選取距癌緣近端10cm以遠(yuǎn)的正常直腸石蠟包埋組織144例作為對照組。提取癌組織DNA,經(jīng)聚合酶鏈反應(yīng)擴(kuò)增 K-ras基因,采用DNA直接測序法檢測K-ras基因的突變情況。
結(jié)果  144例直腸癌患者中有32例(22.22%) K-ras基因第12、13位密碼子發(fā)生突變,漢族與維吾爾族突變率分別為20.41%(20/98)和26.09%(12/46),二者比較差異無統(tǒng)計(jì)學(xué)意義(P>0.05)。對照組中均未見K-ras基因第12、13位密碼子的突變。K-ras基因突變僅與腫瘤浸潤深度有關(guān)(T1+T2為25.0%,T3+T4為75.0%,P=0.01),與民族、性別、腫瘤部位、分化程度及淋巴結(jié)轉(zhuǎn)移均無關(guān)(P>0.05)。
結(jié)論  在維吾爾族與漢族直腸癌患者中K-ras基因第12、13位密碼子突變均很常見,但在突變頻率上維吾爾族與漢族直腸癌患者間無差異,K-ras基因突變與直腸癌的侵犯深度有關(guān)。
