Hepatocellular carcinoma (HCC) is often diagnosed at advanced stage where effective therapies are lacking. Identification of new scoring system is needed to discriminate HCC patients from those with chronic liver disease. Based on the link between vascular endothelial growth factor (VEGF) and HCC progression, we aimed to develop a novel score based on combination of VEGF and routine laboratory tests for early prediction of HCC. VEGF was assayed for HCC group (123), liver cirrhosis group (210), and control group (50) by enzyme-linked immunosorbent assay (ELISA). Data from all groups were retrospectively analyzed including α-fetoprotein (AFP), international normalized ratio (INR), albumin and platelet count, transaminases, and age. Areas under receiving operating curve (ROC) were used to develop the score. A novel index named hepatocellular carcinoma-vascular endothelial growth factor score (HCC-VEGF score) = 1.26 (numerical constant + 0.05 × AFP (U l(-1)) + 0.038 × VEGF (ng ml(-1)) + 0.004 × INR - 1.02 × albumin (g l(-1)) - 0.002 × platelet count × 10(9) l- (1) was developed. HCC-VEGF score produce area under ROC curve of 0.98 for discriminating HCC patients from liver cirrhosis with sensitivity of 91 % and specificity of 82 % at cutoff 4.4 (i.e., less than 4.4 considered cirrhosis and greater than 4.4 considered HCC). Hepatocellular carcinoma-VEGF score could replace AFP in HCC screening and follow up of cirrhotic patients.
肝细胞癌(HCC)往往在缺乏有效治疗方法的晚期才被诊断出来。需要识别新的评分系统,以区分HCC患者和慢性肝病患者。基于血管内皮生长因子(VEGF)与HCC进展之间的联系,我们旨在开发一种基于VEGF和常规实验室检查相结合的新评分系统,用于HCC的早期预测。通过酶联免疫吸附测定(ELISA)对HCC组(123例)、肝硬化组(210例)和对照组(50例)进行VEGF检测。对所有组的数据进行回顾性分析,包括甲胎蛋白(AFP)、国际标准化比值(INR)、白蛋白和血小板计数、转氨酶及年龄。采用接受操作曲线(ROC)下面积来制定该评分系统。开发了一种名为肝细胞癌-血管内皮生长因子评分(HCC-VEGF评分)的新指标,即HCC-VEGF评分 = 1.26(数值常数 + 0.05×AFP(U l⁻¹) + 0.038×VEGF(ng ml⁻¹) + 0.004×INR - 1.02×白蛋白(g l⁻¹) - 0.002×血小板计数×10⁹ l⁻¹)。HCC-VEGF评分在区分HCC患者和肝硬化患者时,ROC曲线下面积为0.98,在临界值4.4时,敏感性为91%,特异性为82%(即小于4.4视为肝硬化,大于4.4视为HCC)。肝细胞癌-VEGF评分可在肝硬化患者的HCC筛查和随访中替代AFP。
