摘要 目的探讨PTEN基因与肝细胞癌发生、发展,侵袭转移的关系及其临床病理意义。方法肝细胞癌手术切除标本46例,采用免疫组化SABC法染色检测。结果肝细胞癌患者PTEN基因阳性率为65.2%(30/46),癌旁组织中阳性率为90.9%(30/33),两者表达与患者年龄,性别,肿瘤大小及AFP,HBsAg是否阳性无关,与肝细胞癌病理分级,包膜及癌栓的有无关系密切。其中高分化组(I+Ⅱ级)阳性率为80%(20/25),低分化组(Ⅲ+Ⅳ级)阳性率为47.6%(10/21)(P〈0.05),包膜完整者阳性率为88.2%(15/17),无或包膜不完整者阳性率为51.7%(15/29),有癌栓者38.4%(5/13),无癌栓者75.8%(25/33)(P〈0.05)。结论PTEN基因在肝细胞癌发生、发展、侵袭转移过程中起抑制作用。
