摘要 目的:分析胃癌组织中核因子-κВ(NF-κB)-p65成分的表达与临床病理特征的关系,从而探讨NF-κB在胃癌的发生、发展中的意义。方法:收集1999年3月至2003年6月我院普外科手术切除并经病理组织学证实的胃癌标本92例,胃镜下活检的慢性胃炎标本50例。采用免疫组化SABC法检测组织标本中的NF-κB-p65,比较两组表达的差异及研究NF-κB与临床病理特征的关系。结果:在92例胃癌标本中70例NF-κB-p65表达阳性(76.1%),可见明显的核移位现象,高于癌旁组织、炎症组织。癌旁组织、炎症组织阳性率分别为40.2%(37/92),54.0%(27/50)。胃癌的病理分级低分化组的NF-κB-p65阳性表达率为63.3%(19/30),高中分化组阳性率为82.3%(51/62),两者差异有统计学意义(P<0.01)。在胃癌中,年龄、性别、浸润深度、淋巴结有无转移等分组之间NF-κB-p65阳性率及DNA结合活性差异无统计学意义(P>0.05)。结论:NF-κB在胃癌组织中明显活化,与肿瘤的分化程度具有相关性。
