摘要 目的:检测大肠癌组织Survivin和环氧化酶(Cox-2)的表达情况,并探讨二者之间的相关性. 方法:应用免疫组织化学(S-P)方法分别检测Survivin和Cox-2在40例大肠癌及34例正常大肠黏膜中的表达情况. 结果:Survivin的阳性表达定位于细胞质,在大肠癌组织中其阳性率为67.5%,正常大肠黏膜组织中阳性率为0, 二者差异十分显著(P<0.01);Cox-2的阳性表达定位于细胞质,在大肠癌组织中其阳性率为90%,正常大肠黏膜组织中阳性率为11.8%,二者差异十分显著(P<0.01).Survivin 和Cox-2的表达具有一定的相关性(r=0.39,P<0.05). 结论:大肠癌组织中Survivin过表达可能是最终导致大肠癌发生的突破点,Survivin和Cox-2的协同表达表明大肠癌中的抑制凋亡是通过多种通路实现的.
