【摘要】 目的 探讨血管内皮生长因子(VEGF)及其受体Flk1在大肠癌发生中的作用。方法 采用免疫组化技术检测正常大肠粘膜15例(NM组)、大肠腺瘤27例(Ad组)、大肠癌81例(CC组)中VEGF及其受体Flk1的表达。结果 从NM到Ad到CC组VEGF及其受体Flk1的表达逐渐增高、增强组间均存在显著差异(P均<0.01)。结论 VEGF及其受体Flk1可作为大肠正常组织恶变的不良信号,检测VEGF及其受体Flk1可作为预测组织恶变的参考指标。【关键词】 大肠癌;血管内皮生长因子;Flk1;免疫组化

【Abstract】 Objective To investigate the significance of VEGF and its receptor Flk1 expression in normal mucosa (NM),adenoma and colorectal carcinoma(CC). Methods SP immunohistochemical staining was used to examine expressions of VEGF, Flk1 among 15 cases of NM,27 cases of Ad and 81 cases of CC paraffinembedded specimens. Rank sum test was used to analyze the expressions of VEGF and Flk1.Results The expression of VEGF and Flk1 from NM to Ad to CC appeared an upward tendency. There were significant differences in VEGF and Flk1 expression between the two groups(P<0.01,P<0.01). Conclusions VEGF,Flk1 as bad signals in the occurrence of CC could be regarded as predictive factors of CC. ......
