摘要: 目的 探究外周血微小核糖核酸-155(microribonucleic acid-155,miR-155)、微小核糖核酸-181a(microribonucleic acid-181a,miR-181a)在乙型肝炎病毒(hepatitis B virus,HBV)相关肝细胞癌(hepatocellular carcinoma,HCC)患者中的表达水平,分析两者对HBV HCC的诊断价值及与临床病理特征和生存预后的关系。方法 选取2017年1月至2021年1月在重庆市中医院接受治疗的HBV HCC患者117例作为肝细胞癌组、HBV相关良性肝病117例作为慢性肝病组,包括慢性乙型肝炎患者71例、乙型肝炎肝硬化患者46例,采集外周血,比较两组miR-155、miR-181a表达差异,分析miR-155、miR-181a表达与HBV相关HCC患者发病及临床病理特征的关系。绘制受试者操作特征(receiver operating characteristic,ROC)曲线评价外周血miR-155、miR-181a表达对HBV相关HCC的诊断价值。随访3年,Kaplan-Meier法分析miR-155、miR-181a对HBV相关HCC患者生存率的影响。结果 肝细胞癌组外周血miR-155、miR-181a表达均较慢性肝病组高(P<0.05)。外周血miR-155、miR-181a表达与HBV相关HCC发病、HBV-DNA载量、门静脉侵袭、临床分期、淋巴结转移呈正相关,与分化程度呈负相关(P<0.05)。外周血miR-155、miR-181a诊断HBV相关HCC的曲线下面积(area under the curve,AUC)值分别为0.768、0.818,二者联合诊断AUC值0.923,明显高于各指标单独诊断,此时最佳敏感度、特异度分别为83.76%、88.03%。miR-155高表达亚组3年生存率为82.14%,明显低于低表达亚组的94.74%(P<0.05);miR-181a高表达亚组3年生存率为80.36%,明显低于低表达亚组的96.49%(P<0.05)。结论 HBV相关HCC患者外周血miR-155、miR-181a表达异常升高,二者共同参与HBV相关HCC发病及恶性进展,检测其水平对于疾病诊断及预后预测具有一定价值。

Abstract: Objective To explore the expression levels of microribonucleic acid-155 (miR-155) and microribonucleic acid-181a (miR-181a) in patients with hepatitis B virus (HBV)-related hepatocellular carcinoma (HCC), analyze their diagnostic value for HBV-related HCC, as well as their relationship with clinical pathological characteristics and survival prognosis. Method A total of 117 HBV-related HCC patients who received treatment in Chongqing Hospital of Traditional Chinese Medicine from January 2017 to January 2021 were selected as the hepatocellular carcinoma group, and 117 cases of HBV-related benign liver disease were selected as the benign liver disease group. The peripheral blood was collected for comparison between the two groups on miR-155 and miR-181a expression differences, and analysis of the relationship between miR-155 and miR-181a expression and the pathogenesis and clinical pathological characteristics of HBV-related HCC patients. Receiver operating characteristic (ROC) curve was drawn to evaluate the diagnostic value of peripheral blood miR-155 and miR-181a expression for HBV-related HCC. After a 3-year follow-up, the impact of miR-155 and miR-181a on the survival rate of HBV-related HCC patients was analyzed using Kaplan-Meier method. Result The expressions of miR-155 and miR-181a in peripheral blood of hepatocellular carcinoma group were higher than those of benign liver disease group (P<0.05). The expression of miR-155 and miR-181a in peripheral blood was positively correlated with the onset of HBV-related HCC, HBV-DNA load, portal vein invasion, clinical stage and lymph node metastasis, and negatively correlated with the differentiation degree (P<0.05). The area under the curve (AUC) values of miR-155 and miR-181a in peripheral blood for diagnosing HBV-related HCC were 0.768 and 0.818, respectively, and the AUC value of combined diagnosis was 0.923, which was significantly higher than that of individual diagnosis. At this time, the optimal sensitivity and specificity were 83.76% and 88.03%, respectively. The 3-year survival rate of miR-155 high expression subgroup was 82.14%, significantly lower than that of low expression subgroup (94.74%) (P<0.05). The 3-year survival rate of miR-181a in the high-expression subgroup was 80.36%, which was significantly lower than that in the low-expression subgroup (96.49%) (P<0.05). Conclusion The expression of miR-155 and miR-181a in peripheral blood of HBV-related HCC patients is abnormally elevated, and both of them are involved in the pathogenesis and malignant progression of HBV-related HCC. The detection of their levels is of certain value for disease diagnosis and prognosis prediction.
