摘要
目的研究胰腺癌组织(PCT)、癌旁正常胰腺组织(Non-PCT)中人类激肽释放酶11(KLK11)的表达及其临床意义。方法免疫组织化学(IHC)法对75例胰腺癌患者相配对的PCT、Non-PCT中KLK11的表达加以检测,同时分析KLK11的表达和患者临床病理参数及预后的关系。再通过Western blot和实时荧光定量PCR(qRT-PCR)方法各检测10例相配对的PCT、Non-PCT中KLK11的表达。结果 IHC法显示KLK11主要在PCT导管细胞的胞质当中表达,在PCT组中KLK11的阳性表达率达到了77. 33%(58/75),而Non-PCT组为20%(15/75),差异有统计学意义(P <0. 001)。KLK11的表达与淋巴结的转移(P <0. 001)以及TNM分期(P <0. 001)有显著相关性。Western blot及qRTPCR表明PCT组中KLK11的表达量及其mRNA含量均明显高于Non-PCT组,差异有统计学意义(P <0. 01,P <0. 001)。Kaplan-Meier分析结果表明KLK11高表达的生存时间(平均无病生存期:7. 217个月,平均总生存期:14. 318个月)比KLK11低表达的生存时间(平均无病生存期:16. 939个月,平均总生存期:22. 776个月)显著缩短,差异有统计学意义(P <0. 01)。COX回归模型分析显示KLK11的表达是胰腺癌预后的独立因素,差异有统计学意义(P <0. 01)。结论 KLK11的表达与胰腺癌的淋巴结转移以及TNM分期密切相关,可作为判断胰腺癌预后的独立因素。KLK11的检测对胰腺癌的发生发展及其预后评估具有一定的价值。
