摘要 目的检测信号素ⅢA(Sema 3A)和血管内皮生长因子(VEGF)在宫颈癌中的表达,探讨两者在宫颈癌发生发展中的意义。方法采用免疫组化SP法检测20例正常宫颈、33例宫颈上皮内瘤变(CIN)、52例宫颈癌组织中Sema 3A和VEGF的表达,比较各组织间的阳性表达率。结果 (1)Sema 3A在正常宫颈、CIN、宫颈癌中的阳性表达率逐渐降低,分别为90%、57.6%、30.8%(P<0.05);(2)VEGF在正常宫颈、CIN、宫颈癌中的阳性表达率逐渐升高,分别为15%、48.5%、75%(P<0.05);(3)两者在宫颈癌中的表达均与临床分期、淋巴结转移有关(P<0.05),与患者年龄、组织学类型及病理学分级无关(P>0.05);(4)宫颈癌中Sema 3A与VEGF的表达呈负相关(r=-0.289,P=0.038)。结论宫颈癌中低表达的Sema 3A和高表达的VEGF可能通过血管生成途径促进了宫颈癌的发生发展,有望成为宫颈癌抗血管生成治疗的潜在靶点。
