摘要 目的:研究胰腺癌组织PTCHmRNA的表达及其与胰腺癌分化程度、大小和侵润转移的关系.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PTCHmRNA的表达情况.结果:28例胰腺癌组织中20例胰腺癌组织有PTCHmRNA表达(阳性率71.4%);28例癌旁胰腺组织中无PTCHmRNA的表达;胰腺癌组织和癌旁组织其PTCHmRNA阳性表达率差异有显著性(P<0.001);PTCHmRNA阳性表达率与肿瘤分化程度有关(P=0.035),与肿瘤的大小、淋巴及远处转移无关(P>0.05).结论:PTCHmRNA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.
