目的探讨原发性肝癌、肝硬化、良性肝病患者和健康人血液中XAGE-1b mRNA表达的差异及意义.方法采集125例原发性肝癌患者、23例肝硬化患者、34例良性肝病患者、41例健康志愿者静脉血,实时荧光定量PCR检测其中XAGE-1b mRNA的表达.结果原发性肝癌患者、肝硬化患者、良性肝病患者、健康人血液中XAGE-1b mRNA的表达量分别为3.72(0.93,10.2)×10-5、0(0,0.56)×10-5、0(0,0)×10-5、0(0,0)×10-5.原发性肝癌患者表达量显著高于肝硬化、良性肝病患者和健康人,肝硬化患者表达量高于良性肝病患者和健康人,良性肝病患者与健康人的表达量差异无统计学意义.以8.385×10-7为最佳临界值,XAGE-1b mRNA诊断原发性肝癌的敏感性为80.0%,特异性为89.8%,阳性预测值90.9%,阴性预测值77.9%.肝癌患者的阳性率为80.0%,肝硬化患者的阳性率为30.4%.结论XAGE-1b mRNA可作为一种肿瘤标志物诊断原发性肝癌,并有利于肝癌、肝硬化、良性肝病的鉴别.

Objective To investigate the significance of XAGE-1bmRNA expression in the blood specimens of patients with primary liver cancer, cirrhosis and benign liver diseases and in healthy individuals. Methods Venous blood specimens of patients with primary liver cancer (n= 125), cirrhosis (n= 23), benign liver diseases (n= 34) and healthy individuals (n = 41 ) were collected. XAGE-1b mRNA was detected by real-time fluorescence quantitative PCR. Results The expression levels of XAGE-1b mRNA in patients with primary liver cancer, cirrhosis, benign liver diseases and healthy in dividuals were 3.72 (0.93, 10.2) ×10-5, 0 (0, 0. 56) ×10-5, 0 (0, 0)×10-5, 0 (0, 0) ×10-5, respectively. The XAGE-1b mRNA expression in patients with primary liver cancer was obviously higher than the patients with cirrhosis, benign liver diseases and in healthy individuals. The expression levels for patients with cirrhosis was higher than patients with benign liver diseases and in healthy individuals. The expression levels for patients with benign liver diseases and healthy individuals were similar. With a optimal cut-off value of 8. 385 × 10-7 , the sensitivity, specificity, positive predictive value, and negative predictive value of XAGE-lb mRNA for diagnosing primary liver cancer were 80. 0%, 89.8%, 90.9% and 77.9% respectively. The positive rates for patients with primary liver cancer and cirrhosis were 80.0% and 30.4% respectively. Conclusion XAGE-lb mRNA can be used as a tumor marker for primary liver cancer. It contributes to the differentiation between primary liver cancer, cirrhosis and benign liver diseases.
