摘要
目的 研究胰腺良性和恶性病变组织中cyclinD1、CDK4、p16和Rb的表达及意义。方法 对 5 3例胰腺癌、17例慢性胰腺炎石蜡包埋切片行ABC免疫组织化学法染色。结果 慢性胰腺炎和癌旁上皮组织的cyclinD1、CDK4、Rb阳性率明显低于胰腺癌 ,而p16则相反 ;cyclinD1、CDK4和Rb阳性及p16阴性的慢性胰腺炎和癌旁上皮多为上皮中度至重度不典型增生 ;高分化和未转移胰腺癌cyclinD1、CDK4和Rb阳性率明显低于低分化和有转移的胰腺癌 ,而p16则相反 ;cyclinD1表达与CDK4表达呈密切正相关 ,p16表达与Rb表达呈密切负相关 ,cyclinD1、CDK4表达与Rb表达呈正相关趋势 ,与p16表达呈负相关趋势。结论 cyclinD1、CDK4、p16和Rb表达特征与胰腺癌的发生发展、生物学行为及其预后有密切关系。
