In addition,to gether expression rate of bcl-2、p53 and p21 in the follow-up patient s (16 cases) was 50%(8/16).Conclusion:The results suggest that the occurrence of HCC has a close relation with the over expression and mutation of bcl-2、p53 a nd p21 gene proteins.There may be a joint action among these genes.Because the exp ression of bcl-2、p53 and p21 can reflect the differential and proliferative de grees of tumour cells,it can be used as the indicators in the diagnosis and pro gnosis of HCC.

研究结果提示：HCC的发生、发展与bcl-2、p53和p21 蛋白的异常表达或突变有关；bcl-2、p53和p21之间可能存在相互协同作用，对HCC的预后有一定的影响；bcl-2、p53和p21蛋白过度表达反应了HCC癌细胞的分化程度及增殖情况，因而可作为HCC诊断和预后的参考指标之一。
