摘要
目的:通过检测血管生成素(ANG)在人正常早孕绒毛组织、葡萄胎及妊娠滋养细胞肿瘤中表达的差异性,探讨ANG在妊娠滋养细胞疾病(GTD)表达的意义。方法:采用免疫组化(En Vision)法检测人正常早孕绒毛组织28例、葡萄胎组织26例、妊娠滋养细胞肿瘤组织14例(其中侵蚀性葡萄胎1例、绒毛膜癌12例、胎盘部位滋养细胞肿瘤1例)中ANG蛋白的表达以及定位情况。结果:ANG蛋白在人正常早孕绒毛组织、葡萄胎及妊娠滋养细胞肿瘤组织中均有表达且主要定位于细胞质和细胞膜、少量表达于细胞核;ANG阳性表达率葡萄胎组(100.0%)高于正常早孕绒毛组(60.7%)(P<0.05)和妊娠滋养细胞肿瘤组(85.7%)(P<0.05),妊娠滋养细胞肿瘤组高于正常早孕绒毛组(P<0.05)。在妊娠滋养细胞肿瘤中,ANG阳性表达率在年龄≥40岁组(83.3%)高于年龄<40岁组(75.0%)(P<0.05);临床分期晚期组(Ⅲ、Ⅳ期)(88.9%)高于早期组(Ⅰ期、Ⅱ期)(80.0%)(P<0.05);FIGO预后评分高危组(87.5%)高于低危组(83.3%)(P<0.05)。结论:ANG在GTD组织中的表达明显高于在正常早孕绒毛组织,且在妊娠滋养细胞肿瘤晚期、高危患者表达增高,表明ANG的过表达可能参与了GTD的发生过程。
