摘  要:目的研究Rb、P57^kip2在人肝细胞癌发生不同阶段的表达及意义。方法采用免疫组化法检测18例慢性肝炎、20例肝硬化、18例癌周肝硬化和22例肝细胞癌共78例标本中Rb、P57^kip2蛋白的表达。结果Rb、P57^kip2蛋白在慢性肝炎组呈低-中表达(阳性表达率分别为44.44%和61.11%)、肝硬化组表达明显下降(阳性表达率分别为25%和40%)、而癌周肝硬化组和肝细胞癌组表达逐渐增强(阳性表达率分别为66.67%、83.33%和72.73%、72.73%)。癌周肝硬化组与肝硬化组差异有统计学意义(P〈0.05),但与肝癌组差异无统计学意义(P〉0.05)。结论Rb与P57^kip2的表达异常可能参与了肝细胞癌的发生、发展。Objective To study the expression of Rb, P57^kip2 in different phases of hepatocarcinogenesis( HCC ). Methods Immunohistoehemieal staining for Rb and P57^kip2 protein was performed in formalinfixed and paraffin-embedded sections of 78 cases including chronic hepatitis( n = 18 ), liver cirrhosis( n = 20), paraeaneerous cirrhosis( n = 18) and hepatoeellular carcinoma tissue( n = 22). Results The positive rates of Rb and P57^kip2 protein were 44.44% ( 8/18 ) and 61.11% ( 11/18 ) in chronic hepatitis group, 25% (5/20) and 40% (8/20) in liver cirrhosis group, 66. 67% (12/18) and 83.33% (15/18) in paraeaneerous cirrhosis group, 72. 73% (16/22) and 72. 73% (16/22) in hepatoeellular carcinoma group respectively. The positive rate of Rb and P57^kip2 protein in paraeaneerous cirrhosis was significantly higher than that in liver cirrhosis ( P 〈 0. 05 ) , but there was no significant difference between paraeaneerous cirrhosis and hepatoeellular carcinoma ( P 〉 0. 05 ). Conclusion The abnormal expression of Rb and P57^kip2 may be involved in the genesis and development of hepatocellular carcinoma.
