摘要 目的测定人端粒酶逆转录酶(hTERT)mRNA在胃癌组织中的表达水平并探讨其临床生物学意义。方法应用实时荧光定量RT-PCR分析了96例手术切除的新鲜胃癌组织、癌旁正常胃黏膜组织及50例胃溃疡组织中hTERT mRNA的表达水平。结果胃癌组织hTERT mRNA表达水平(17.38±1.28)copies/ml显著高于癌旁正常胃黏膜组织(0.24±0.10)copies/ml,(P<0.001)和良性胃溃疡组(1.04±0.28)copies/ml,(P<0.001)。多变量分析表明,hTERT mRNA表达水平分别与患者性别、年龄、肿瘤大小、肿瘤生长方式、肿瘤分化程度、淋巴管侵犯及静脉侵犯均无显著性差异(P>0.05),而分别与浸润深度、淋巴结转移、远处转移、pTNM分期及CEA有显著性差异(P<0.05)。结论hTERT高水平表达常意味着胃癌恶性程度较高且病期较晚,测定胃癌组织中hTERT的水平对判断胃癌浸润、转移及病期进展情况有一定诊断价值。
