Abstract： 目的探讨P33ING1 表达在胰腺癌的发生、发展中的生物学特征和临床意义.方法选取胰腺癌、癌旁组织与胰腺良性病变标本,应用组织芯片(又称组织微阵列)技术和免疫组化方法研究P33ING1、P53和MDM2在胰腺良恶性病变中的表达情况.结果 P33ING1在胰腺癌与癌旁组织中表达的阳性率分别为77.2%(129/167)、60.4%(61/101).P33ING1的阳性表达与肿瘤的分化和神经受累显著相关(P<0.05);P53的阳性表达与肿瘤的分化、淋巴结转移和神经受累均显著相关(P<0.05);MDM2的阳性表达与肿瘤的分化显著相关(P<0.05).胰腺癌组织中P33ING1与P53、MDM2的表达均呈正相关.结论 P33ING1在胰腺癌的发生发展中可能起重要作用,P33ING1与P53及MDM2的联合表达与胰腺癌的临床生物学行为有关.
