Abstract： 目的:探讨胃癌内核转录因子κB(nuclear factor-κB,NF-κB)活化对血管内皮生长因子(vascular endothelial growth factor,VEGF)表达的影响及对预后的影响.方法:选择胃癌根治术切除标本41例,应用免疫组织化学方法测定NK-κB,VEGF及CD34的表达,检测结果与胃癌临床病理学多参数进行经统计分析.结果:NF-κB呈活化型型表达者占受检病例的68.3%,VEGF呈强阳性表达者占受检病例的70.73%.NF-κB活化型表达组与VEGF高表达组有较高一致性(κ=0.393,P=0.012).NF-кB与VEGF同时表达组微血管密度明显较NF-κB与VEGF同时阴性组高(P=0.000),NF-κB与VEGF同时表达组生存期明显短于NF-κB与VEGF同时阴性组(P=0.035).结论:胃癌细胞通过活化NF-κB信号通道促进VEGF高表达,从而影响肿瘤内微血管密度及预后.
