Abstract
背景与目的目前对非小细胞肺癌(non-small cell lung cancer, NSCLC)患者预后的研究很多,有些临床病理因素已被公认与预后有关,本研究旨在对淋巴管密度(lymphatic vessel density, LVD)、微血管密度(microvessel density, MVD)及癌胚抗原信使核糖核酸(carcinoembryonic antigen messenger ribonucleic acid, CEAmRNA)和肿瘤转移抑制基因KAI1、Kiss-1的表达与NSCLC患者预后的关系进行探讨。方法选取57例NSCLC患者,采用逆转录巢式聚合酶链反应(nested-RT-PCR)和微流控芯片(micro-fluid chip)技术对外周血CEAmRNA的表达进行检测;采用免疫组织化学技术对肺癌组织LVD、MVD和KAI1、Kiss-1的表达进行检测,并对所有患者进行随访分析。结果全组的5年生存率为18%,中位生存期为34个月;单因素分析显示TNM分期、淋巴结有无转移、CEAmRNA的阳性表达、MVD、LVD和Kiss-1的表达对生存有影响;多因素分析显示TNM分期、淋巴结有无转移和CEAmRNA的表达是影响预后的独立危险因素。结论在NSCLC患者中MVD、LVD和Kiss-1及CEAmRNA的表达可以在一定程度上反映患者的预后。
