摘要:
目的 探究慢性乙型肝炎(CHB)患者发生肝细胞癌(HCC)的危险因素。 方法 收集2013年1月—2015年6月北京地坛医院确诊的CHB且随访超过3年的患者,共1239例。其中非肝硬化患者1108例,肝硬化患者131例。收集患者的一般资料及实验室检查指标并计算APRI、FIB-4及mFZB-4评分。符合正态分布的计量资料2组间比较采用t检验;非正态分布的计量资料2组间比较采用Mann-Whitney U检验。计数资料2组间比较采用χ2检验。影响HCC发生的独立危险因素采用Cox回归分析。采用受试者工作特征曲线下面积(AUC)比较3种评分对CHB患者发生HCC的预测能力,采用DeLong检验对各个评分的AUC进行比较。通过拟合优度检验分析mFIB-4评分校准能力。使用Kalplan-Merier法对HCC发生进行分析,log-rank法进行比较。 结果 中位随访时间为4.6年,37例(3.0%)患者发生HCC。多因素Cox回归分析显示,年龄(HR=1.046,95%CI:1.018~1.074,P=0.001)、ALT (HR=0.995,95%CI:0.992~0.999,P=0.008)、AST (HR=0.994,95%CI:0.990~0.998,P=0.020)和PLT (HR=0.988,95%CI:0.981~0.994,P=0.001)是影响HCC发生的独立危险因素。mFIB-4、FIB-4、APRI评分的AUC分别为0.771、0.658、0.676,其中mFIB-4评分的AUC大于FIB-4评分(Z=5.629, P<0.000 1)及APRI评分(Z=4.243, P<0.000 1)。与mFIB-4<2.68的患者相比,mFIB-4 ≥2.68的患者HCC发生风险更高(Z=37.840, P<0.000 1)。 结论 年龄、ALT、AST和PLT是CHB患者发生HCC的独立危险因素。与FIB-4,APRI评分相比,mFIB-4评分对CHB患者发生HCC的预测价值更高。mFIB-4 ≥2.68的CHB患者是发生HCC的高危人群。 Abstract:Objective To investigate the risk factors for hepatocellular carcinoma (HCC) in patients with chronic hepatitis B (CHB). Methods A total of 1239 patients who were diagnosed with CHB in Beijing Ditan Hospital from January 2013 to June 2015 and were followed up for more than 3 years were enrolled, among whom 1108 had no liver cirrhosis and 131 had liver cirrhosis. General information and laboratory markers were collected. The chi-square test was used for comparison of categorical data between groups, and the t-test or the Mann-Whitney U test was used for comparison of continuous data between groups. The t-test was used for comparison of normally distributed continuous data between two groups, and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between two groups; the chi-square test for comparison of categorical data between two groups. A multivariate Cox regression analysis was used to identify the independent risk factors for HCC. The area under the ROC curve (AUC) was used to compare the ability of fibrosis-4 (FIB-4), modified FIB-4 (mFIB-4), and aspartate aminotransferase-to-platelet ratio index (APRI) scores to predict the development of HCC, and the DeLong test was used for comparison of AUC. Goodness of fit was used to evaluate the calibration ability of mFIB-4 score. The Kaplan-Meier method was used to analyze the development of HCC, and the log-rank test was used for comparison. Results The median follow-up time was 4.6 years, and of all patients, 37 (3.0%) developed HCC. The multivariate Cox regression analysis showed that age (hazard ratio [HR]=1.046, 95% confidence interval [CI]: 1.018-1.074, P=0.001), alanine aminotransferase (ALT) (HR=0.995, 95%CI: 0.992-0.999, P=0.008), aspartate aminotransferase (AST) (HR=0.994, 95%CI: 0.990-0.998, P=0.020), and platelet count (PLT) (HR=0.988, 95%CI: 0.981-0.994, P=0.001) were independent risk factors for HCC in CHB patients. The mFIB-4, FIB-4, and APRI scores had an AUC of 0.771, 0.658, and 0.676, respectively, and mFIB-4 score had a significantly higher AUC than FIB-4 score (Z=5.629, P < 0.000 1) and APRI score (Z=4.243, P < 0.000 1). Compared with the patients with mFIB-4 < 2.68, the patients with mFIB-4 ≥2.68 had a significantly higher risk of HCC (Z=37.840, P < 0.000 1). Conclusion Age, ALT, AST, and PLT are independent risk factors for HCC in CHB patients. Compared with FIB-4 and APRI scores, mFIB-4 s core has a higher value in predicting HCC in CHB patients. The patients with mFIB-4 ≥2.68 are the high-risk population of HCC. -
