摘要 目的:研究KDR mRNA的表达与子宫内膜癌、卵巢癌、子宫颈癌的关系。方法:应用半定量逆转录聚合酶链式反应(RT-PCR)技术检测妇科恶性肿瘤127例,良性肿瘤和不典型增生80例,正常组织40例的KDR mRNA表达情况。结果:KDR mRNA在子宫内膜癌、卵巢癌、子宫颈癌中的阳性表达分别为73.3%、56.7%、75.0%,相对含量为118.1±15.7、109.2±17.2、108.8±16.3;在子宫内膜不典型增生、卵巢良性肿瘤和宫颈上皮内瘤样病变组织中的阳性表达分别为26.7%、16.7%、42.9%,相对含量为97.6±10.1、92.2±10.0、93.2±14.6;在正常子宫内膜、卵巢和宫颈组织中的阳性表达分别为20.0%、20.0%、13.3%,相对含量分别为80.3±21.4、92.4±10.3、90.5±10.8。三种恶性肿瘤组织中KDR mRNA的阳性表达率和相对含量明显高于其他2组(均P<0.05)。三种恶性肿瘤组织中晚期、有淋巴结转移组的KDR mRNA相对含量高于早期、无淋巴结转移组(P<0.05),而与肿瘤细胞分化程度无确切关系。结论:KDR mRNA的过表达在妇科恶性肿瘤的发生、发展中起重要作用,并与其某些生物学行为有关,可能作为对其进行治疗的靶位点。
