摘要 目的探讨PIK3CA蛋白表达异常与外阴鳞癌发生发展的关系。方法选取外阴鳞癌组织30份,外阴重度不典型增生、原位癌组织16份,外阴轻、中度不典型增生组织20份;另选择正常外阴皮肤组织10份作为对照。应用免疫组化方法检测上述组织中PIK3CA蛋白的表达,并分析其与外阴鳞癌发生发展的关系。结果外阴鳞癌组织中,PIK3CA蛋白表达水平显著高于正常外阴皮肤组织和外阴轻、中度不典型增生组织(P<0·01);但与外阴重度不典型增生、原位癌组织比较,差异无显著性(P>0·05)。外阴重度不典型增生、原位癌组织与外阴轻、中度不典型增生组织和正常外阴皮肤组织分别比较,差异均具有显著性(P<0·01)。外阴轻、中度不典型增生组织与正常外阴皮肤组织比较,差异无显著性(P>0·05)。结论PIK3CA蛋白表达异常可能在外阴鳞癌的发生发展中起一定作用;PIK3CA蛋白有望成为外阴鳞癌早期诊断指标。
