目的 探討抑癌基因 Lumican mRNA在胃癌組織中的表達(dá)及其在胃癌發(fā)生、發(fā)展中的意義。
方法 采用逆轉(zhuǎn)錄聚合酶鏈反應(yīng)(RT-PCR)方法檢測(cè)66例胃癌組織及其相應(yīng)的近癌旁組織及正常組織中Lumican mRNA的表達(dá)，并分析胃癌組織中Lumican mRNA表達(dá)與其臨床病理特征的關(guān)系。
結(jié)果 Lumican mRNA在胃癌組織、近癌旁組織及正常組織中的表達(dá)缺失率分別為42.4%(28/66)、15.2%(10/66)及0(0/66)。有淋巴結(jié)轉(zhuǎn)移者胃癌組織中Lumican mRNA表達(dá)缺失率(61.1%)明顯高于無(wú)淋巴結(jié)轉(zhuǎn)移者(20.0%)，差異有統(tǒng)計(jì)學(xué)意義(χ2=11.323,P=0.001); 晚期(Ⅲ、Ⅳ期)胃癌組織中Lumican mRNA表達(dá)缺失率(61.5%)明顯高于早期(Ⅰ、Ⅱ期，30.0%），差異有統(tǒng)計(jì)學(xué)意義(χ2=6.417,P=0.011; 胃癌組織中Lumican mRNA表達(dá)缺失與腫瘤分化程度無(wú)關(guān)(χ2=1.576,P=0.455)。
結(jié)論 Lumican mRNA表達(dá)缺失可能在胃癌的發(fā)生和發(fā)展過(guò)程中起重要作用, 并影響其預(yù)后。
