Abstract： 目的:观察nm23-H1的表达与临床病理特征的关系,探讨nm23-H1的表达与大肠癌发生、发展、转移的作用.方法:选取行结、直肠癌根治术的患者63例,并取腺瘤组织16例做对照.应用免疫组化S-P法检测大肠癌患者癌组织、同源癌旁组织及正常黏膜组织和大肠腺瘤组织nm23-H1的表达.结果:nm23-H1在癌组织中表达(58.7%)显著低于癌旁组织(90.5%)、正常黏膜组织(96.0%)及腺瘤组织(93.8%)(P＜0.05).在大肠癌组织中,无淋巴结转移者nm23-H1表达(73.3%)显著高于有淋巴结转移者(45.5%)(P＜0.05).大肠癌中nm23-H1表达与肿瘤分化程度呈正相关(r=0.192,P＜0.05),与肿瘤浸润深度呈负相关(r=-0.263,P＜0.05).nm23-H1表达程度与患者年龄、性别、肿瘤大体分型、组织学类型、同期肿瘤大小均无关.结论:nm23-H1表达下调是大肠癌发生、发展中的重要分子生物学事件,可作为提示肿瘤分化、侵袭和淋巴结转移的一项指标.
