摘要 目的 :探讨凋亡抑制基因survivin在大肠肿瘤组织中的表达 ,及其与血管内皮生长因子 (VEGF) ,碱性成纤维细胞生长因子 (b FGF)和肿瘤内微血管密度 (IMVD)的相关性。方法 :采用免疫组织化学方法检则survivin ,VEGF ,b FGF和CD3 4在 10例正常大肠组织和 5 0例大肠肿瘤组织中的表达。结果 :survivin基因在正常大肠组织中不表达 ,在 5 0例大肠肿瘤组织中 ,阳性率为48%,与大肠肿瘤的Ducks分期 ,淋巴结转移密切相关 ;VEGF在正常大肠组织也不表达 ,在 5 0例大肠肿瘤组织中 ,阳性率为 74%,与大肠的Ducks分期 ,淋巴结转移密切相关 ;b FGF在正常大肠组织中不表达 ,在 5 0例大肠肿瘤组织中 ,阳性率为 5 8%,与大肠肿瘤的Ducks分期 ,淋巴结转移密切相关 ;survivin ,VEGF ,b FGF在大肠肿瘤组织中的表达均于肿瘤内微血管密度 (IMVD)成正相关 ;survivin和促血管形成因子VEGF ,b FGF在大肠肿瘤组织中的表达密切相关。结论 :survivin是血管的保护性基因 ,参与了肿瘤血管的形成。
