摘要 目的:探讨FAK、uPA在胃癌原发灶和转移淋巴结中表达及临床意义。方法:应用免疫组织化学SP法检测FAK、uPA在60例胃癌组织和转移淋巴结中的表达。结果:FAK、uPA均在胃癌组织细胞胞浆内表达,阳性表达率分别为65.8%,73.3%;FAK、uPA表达与胃癌淋巴结转移(P<0.05)及浆膜浸润相关(P<0.05);FAK在转移淋巴结中的阳性表达率为(39.1%)较相应胃癌原发灶中FAK阳性表达率(87.9%)显著降低(P<0.05);转移淋巴结中uPA阳性表达率(97.8%)显著高于相应胃癌原发灶中uPA阳性表达率(84.8%),差异有统计学意义(P<0.05)。结论:FAK、uPA表达可作为判断胃癌恶性行为重要生物学指标;FAK低表达有助于癌细胞定位和繁殖,uPA在转移淋巴结中表达水平高于原发灶,在胃癌淋巴结转移过程中可能发挥了重要作用。
