摘要 目的研究缺氧诱导因子-1α(Hypoxia Inducible Factor-1 alpha,HIF-1α)和血管内皮生长因子(Vas-cular Endothelial Growth Fctor,VEGF)的基因产物在宫颈鳞癌组织中的表达及其意义。方法应用免疫组织化学En-visionTM二步法检测86例宫颈鳞癌和10例正常宫颈组织中HIF-1α和VEGF蛋白的表达。结果HIF-1α在86例宫颈鳞癌和10例正常宫颈组织中的阳性表达率分别为55.8%(48/86)和0%(0/10),差异有显著性(P<0.01)。宫颈鳞癌组织中,HIF-1α表达与宫颈鳞癌的肿块大小、FIGO分期、组织学分级、淋巴结转移和肿瘤坏死密切相关。VEGF蛋白在86例宫颈鳞癌和10例正常宫颈组织中的阳性表达率分别为61.6%(53/86)和0%(0/10),差异有显著性(P<0.01)。宫颈鳞癌组织中,VEGF表达与宫颈鳞癌的肿块大小、FIGO分期、组织学分级、淋巴结转移和肿瘤坏死呈正相关。HIF-1α和VEGF蛋白的表达与患者年龄和术后5年生存率均无关。Spearman相关分析发现HIF-1α与VEGF表达程度呈正相关(r=0.636,P<0.01)。结论宫颈鳞癌组织中HIF-1α基因表达显著增高,还可能诱导VEGF的过表达并与宫颈鳞癌的侵袭性生物学行为密切相关。
