Abstract： 目的研究胰腺癌组织SMO mRNA的表达及其与临床肿瘤指标的关系.方法收集28例手术切除的新鲜胰腺癌及癌旁胰腺组织,利用RT-PCR方法分别检测癌组织和癌旁胰腺组织SMO mRNA的表达情况.结果 28例胰腺癌组织中20例胰腺癌组织有SMO mRNA表达(阳性率71.4%);28例癌旁胰腺组织中无SMO mRNA的表达;胰腺癌组织和癌旁组织SMO mRNA阳性表达率差异有显著性(P＜ 0.01);SMO mRNA阳性表达率与肿瘤分化程度有关(P＜ 0.05),与肿瘤的大小、淋巴结及远处转移无关(P ＞ 0.05).结论 SMO mRNA在胰腺癌组织中有较高的阳性表达率,检测其表达有助于胰腺癌的诊断,并可作为判断胰腺癌恶性程度的重要指标.
