摘要 目的探讨磷酸化蛋白激酶B(p-AKT)和与张力蛋白同源的第10染色体丢失的磷酸酶基因(PTEN)在上皮性卵巢癌发生发展中的作用。方法采用免疫组织化学方法检测10份正常卵巢组织(正常组)、20份卵巢良性上皮性肿瘤(良性组)、60份卵巢上皮性癌组织(卵巢癌组)中p-AKT和PTEN表达。结果 p-AKT在正常组、良性组阳性表达率显著低于卵巢癌组;PTEN蛋白在卵巢癌组表达缺失,显著低于正常组、良性组,P均<0.01。p-AKT和PTEN蛋白表达与卵巢癌临床分期、组织学分级、淋巴结转移和远处转移显著相关(P均<0.01),与年龄、病理类型、腹水无关;两者在卵巢癌组织中的表达呈负相关(r=-0.497,P<0.001)。结论 p-AKT过表达伴随PTEN表达缺失参与了卵巢癌的发生发展。
