摘要: 目的与方法:为了阐明P53 蛋白在人肝癌细胞中表达及临床意义,应用了免疫组织化学染色方法检测肝细胞癌P53 蛋白表达情况。结果:49 %(36/ 74) 的病例显示有P53 蛋白的表达,低分化癌的P53 蛋白表达率显著高于高、中分化癌(χ2 检验P < 0105) 。结论:这些资料显示:导致P53 蛋白异常表达的P53 基因突变是肝细胞癌的一种常见的分子结构改变,是评价肝细胞癌预后有价值的一个生物学指标。

Abstract: Purpose and Methods : To evaluate the P53 protein expression and clinical significance in human hepatocellular carcinoma ( HCC) , the expression of P53 protein was detected in HCC by immunohistochemical method. Results : The result s showed that P53 protein was positive in 49 % (36/ 74) of HCC , and there was significant correlation between P53 protein expression and HCC histologic grade. Conclusion : The results suggested that the over2expression of P53 caused by P53 gene mutation is a common kind of molecular st ructure changes in HCC. In addition , P53 protein may be used as a valuable biomaker of HCC.

Key words: P53 gene, mutation, immunohistochemist ry, hepatocellular carcinoma.
