摘要 [目的]探讨诱导型一氧化氮合酶(iNOS)在喉癌组织中的表达与血管内皮生长因子-C(VEGF-C)、淋巴管密度(LVD)、淋巴结转移和预后的相关性。[方法]以45例经病理确诊的喉癌组织为实验组,20例喉良性病变组织为对照组,采用免疫组织化学检测iNOS和VEGF-C的表达,采用5′-核苷酸酶染色(5′-Nase)计数LVD,并结合临床病理特征和生存资料进行相关分析。[结果]喉癌组织中iNOS和VEGF-C的阳性表达率分别为71.1%和37.8%,较对照组显著增加(P<0.05),在喉癌组织中iNOS表达与瘤内和瘤周LVD、淋巴结转移、TNM临床分期、淋巴管浸润有关(P<0.05)。iNOS和VEGF-C表达正相关(r=0.396,P<0.05),iNOS阳性表达者生存率显著低于阴性表达者(P<0.05)。[结论]喉癌组织中iNOS过表达可能通过上调VEGF-C表达促进喉癌淋巴管生成和淋巴结转移,检测iNOS可成为判断喉癌预后新的生物学指标。
