摘要
目的 :探讨cyclinD1及 p2 1WAF1表达与大肠癌发生发展的关系。方法 :用免疫组化SP法对 40例大肠癌标本进行cyclinD1和 p2 1WAF1蛋白表达的检测 ,并与同期 2 8例大肠腺瘤、14例正常大肠粘膜作对比。结果 :cy clinD1和 p2 1WAF1的阳性表达率在大肠腺瘤 (92 .9% )和大肠癌 (6 7.5 % )均显著高于正常大肠粘膜 (35 .7% ) (P<0 .0 1,P <0 .0 5 )。cyclinD1的表达与大肠癌的分化程度及淋巴结转移无关。p2 1WAF1的阳性表达率在大肠癌 (37.5 % )显著低于正常大肠粘膜 (92 .8% ) (P <0 .0 1)。P2 1WAF1表达与大肠癌的分化程度及淋巴结转移有关。结论 :cyclinD1和 p2 1WAF1表达异常在大肠癌的发生、发展中是一个普遍事件。
