摘　　要：目的检测促红细胞生成素(EPO)和促红细胞生成素受体(EPOR)在肝细胞癌(HCC)中的表达情况,并分析二者预测HCC预后的意义。方法采用免疫组化法检测EPO和EPOR在96例HCC组织和11例正常肝脏组织中的表达,分析EPO和EPOR在HCC中表达的相关性,及其与HCC临床病理特征及预后的关系。结果 HCC组织中EPO和EPOR高表达率分别为49.0%、46.9%,明显高于其在正常肝脏组织中的表达(0、0)。HCC组织中EPO与EPOR的表达呈正相关(r=0.207,P<0.05)。EPO和EPOR表达均与Edmondson-Steiner病理分级密切相关(P<0.05)。EPOR低表达组的1、3、5年无瘤生存率分别为76.2%、42.1%及16.5%,高表达组分别为55.6%、14.0%及7.8%,差异有统计学意义(P<0.05)。EPOR低表达组的1、3、5年生存率分别为88.0%、76.0%及46.1%,高表达组分别为80.0%、43.6%及26.8%,差异有统计学意义(P<0.05)。Cox多因素分析显示,卫星结节、EPOR表达是影响HCC患者术后无瘤生存的独立预后因素;卫星结节、血管侵犯和EPOR表达是影响HCC患者术后总生存的独立预后因素。结论 EPOR表达与HCC患者术后无瘤生存和总生存相关,可能是影响HCC预后的分子标志物。Objective To detect the expression of erythropoietin（EPO） and erythropoietin receptor（EPOR） in hepatocellular carcinoma（ HCC） tissues and analyze their predictive value on the prognosis of HCC patients. Methods Immunohistochemistry technique was used to detect the expression of EPO and EPOR in 96 cases of HCC tissues and 11 cases of normal liver tissues. The difference of the expression of the two proteins in two tissues and the correlation of the expression of the two proteins were analyzed. Also,the relationship of the two proteins with clinicopathological features and prognosis of HCC patients were analyzed. Results The high expression rates of EPO and EPOR were 49. 0% and 46. 9% in 96 cases of HCC tissues,higher than 0 and 0 in normal liver tissues. The expression of EPO was positively associated with that of EPOR（ r = 0. 207,P〈0. 05）. The expression of both EPO and EPOR was associated with Edmondson-Steiner histological grade（ P〈0. 05）. The 1-,3-and 5-year disease free survival rates were76. 2%,42. 1% and 16. 5% in low EPOR expression group,significantly higher than 55. 6%,14. 0% and 7. 8% in high EPOR expression group（ P〈0. 05）. Similarly,the 1-,3-and 5-year overall survival rates in low EPOR expression group were 88. 0%,76. 0%and 46. 1%,significantly higher than 80. 0%,43. 6% and 26. 8% in high EPOR expression group（ P〈0. 05）. Multivariate analysis revealed that satellite nodules,the expression of EPOR were independent risk factors of disease free survival（ P〈0. 05）,and satellite nodules,vascular invasion and the expression of EPOR were independent risk factors of overall survival（ P〈0. 05）. Conclusion The expression of EPOR is correlated with disease free survival and overall survival of HCC patients,and maybe a prognosis biomarker of HCC.
