摘要 目的观察PTEN蛋白在胃癌中的表达,探讨其与胃癌临床病理因素的关系。方法采用免疫组化方法检测PTEN蛋白在58例胃癌,23例异型增生和25例正常胃黏膜中的表达。结果PTEN在正常胃黏膜,胃异型增生和胃癌中阳性率分别为100%,69.57%和44.83%。PTEN在胃癌中的阳性率明显低于胃异型增生,正常胃黏膜。进展期胃癌PTEN阳性率低于早期胃癌,两者之间有显著差异;淋巴结转移和低分化腺癌的PTEN阳性率明显低于淋巴结未转移和高中分化腺癌;随着浸润深度的加深,PTEN的阳性率依次降低。结论PTEN的下调在胃癌的发生中起着重要的作用,PTEN表达可能对胃癌的浸润和转移具有抑制作用,可作为胃癌临床病理学行为有效的客观指标。
