摘要 为探讨抑癌基因PTEN表达在卵巢癌发生和演进中的作用及其与VEGF的相互关系,对8例正常上皮来源的卵巢组织、18例卵巢交界性肿瘤、60例上皮性卵巢癌石蜡切片组织,应用免疫组织化学SP法、LSAB法检测PTEN蛋白、VEGF蛋白的表达。结果显示,PTEN在正常卵巢、卵巢交界性肿瘤、上皮性卵巢癌中的阳性表达率分别为87.50%(7/8)、50.00%(9/18)、23.33%(14/60),PTEN的阳性表达率在上皮性卵巢癌中低于正常卵巢、卵巢交界性肿瘤,差异有统计学意义(P<0.01,P<0.05);I/II期阳性表达率37.50%明显高于III/IV期的13.89%(P<0.05);卵巢内膜样癌PTEN阳性表达率7.14%,显著低于浆液样34.78%或黏液样囊腺癌44.44%(P<0.05)。PTEN表达与VEGF表达呈负相关(P<0.01)。
