Abstract

背景与目的肺癌是全球发病率最高的癌症类型,严重威胁着人类健康。肺癌的早期诊断、早期治疗对于肺癌患者的生存尤为重要。血清中的肿瘤标志物作为肿瘤早期诊断的一种重要方法已被广泛应用。然而,肺癌的早期诊断标志物还很少。本研究旨在探讨Lipocalin-2在肺癌患者血清中的表达水平及其临床意义。方法采用酶联免疫吸附法(enzyme linked immunosorbent assay, ELISA)检测Lipocalin-2在60例肺癌患者与63例健康人群外周血血清中的浓度,并分析Lipocalin-2表达水平与肺癌临床特征之间的关系。结果Lipocalin-2在肺癌患者外周血血清中的表达水平明显高于健康人群,差异具有明显统计学意义(P < 0.001)。Lipocalin-2在肺癌患者中的表达与病理组织的分化、分期及淋巴结转移相关,差异具有明显统计学意义(P < 0.05)。Lipocalin-2在病理分化差的肺癌患者血清中的表达高于分化良好患者;在发生淋巴结转移的肺癌患者血清中的表达高于没有发生淋巴结转移患者;在临床Ⅲ期+Ⅳ期肺癌患者中的表达水平显著高于临床Ⅰ期Ⅱ期患者;差异均具有统计学意义(P < 0.05)。结论Lipocalin-2在肺癌患者血清水平中高表达,与病理组织的分化、分期及淋巴结转移相关,有望成为一种潜在的用于临床诊断的新型肺癌肿瘤标志物。
