摘要 目的探讨内皮素-1(ET-1)和中性肽链内切酶(NEP)在卵巢肿瘤组织中的表达及其相关性。方法应用免疫组化法检测56份卵巢癌、19份良性卵巢肿瘤和17份正常卵巢组织中ET-1和NEP的表达,并分析其相关性。结果ET-1在卵巢肿瘤中的表达率高于正常卵巢组织(P<0.05)和卵巢良性肿瘤(P<0.05)。在卵巢癌组织中,ET-1阳性表达率在不同病理类型、病理分级和手术病理分期的病例间差异无统计学意义(P>0.05)。NEP在良性卵巢肿瘤和卵巢癌中的阳性表达率高于正常卵巢组织(P<0.05)。在卵巢癌组织中,NEP阳性表达率在不同病理类型、病理分级和手术病理分期的病例间差异有统计学意义(P<0.05)。结论NEP在卵巢癌组织中可能无法降解ET-1的活性。
