Abstract:

目的检测24-脱氢胆固醇还原酶(3β-hydor-xysteroid-△24reducase,DHCR24)在结直肠癌及癌旁肠黏膜中的表达,探讨其临床意义。方法应用组织芯片技术结合免疫组化法检测第三军医大学3所附属医院结直肠癌术后125例组织标本以及相应63例癌旁肠黏膜中DHCR24的表达。结果DHCR24在125例结直肠癌组织中阳性表达率显著高于癌旁肠黏膜(67.2%vs39.7%,P<0.01),并与肿瘤的分化程度、临床分期、淋巴结转移等有关(P<0.05),结直肠癌患者中DHCR24高表达组比低表达组预后差(P<0.01),临床分期高的结直肠癌患者中,DHCR24的高表达提示了临床预后差(P<0.01),但在临床分期低的患者中不存在这种差异(P>0.05)。结论DHCR24在结直肠癌组织中高表达,且结直肠癌患者中DHCR24高表达组比低表达组预后差,提示其在结直肠癌的发生、发展中可能发挥着重要作用。
