血清自噬相关蛋白7在HBV相关肝细胞癌中的诊断价值

Value of serum autophagy-related protein 7 in diagnosis of HBV-related hepatocellular carcinoma

目的通过分析HBV相关肝细胞癌(HBV-HCC)患者血清自噬相关蛋白7(ATG7)的表达水平,探讨其在HBV-HCC诊断中的临床意义。方法选取2018年6月—2020年12月在福建医科大学孟超肝胆医院住院的慢性乙型肝炎(CHB)患者50例,HCC患者89例,其中HBV-HCC患者67例,非HBV-HCC(nonHBV-HCC)患者22例,另选取同期20例健康体检者为对照(HC)。采集各组个体人口学及AFP等实验室数据,应用ELISA技术检测各组样本血清ATG7水平,绘制ATG7、AFP及二者联合检测受试者工作特征曲线(ROC曲线)并比较其曲线下面积(AUC)。非正态分布的计量资料多组间比较采用Kruskal-Wallis H检验,2组间比较采用Mann-Whitney U检验;计数资料组间比较采用χ^(2)检验;采用Spearman进行相关性分析。结果HBV-HCC组、nonHBV-HCC组、CHB组和HC组的血清ATG7水平分别为22.88(19.79~23.04)ng/mL、17.06(14.45~19.40)ng/mL、19.21(16.65~20.82)ng/mL和13.82(8.70~17.82)ng/mL,差异有统计学意义(χ^(2)=65.144,P<0.001);ATG7诊断HBV-HCC的AUC为0.818(95%CI:0.743~0.879),略高于AFP(AUC=0.777,95%CI:0.698~0.843),差异无统计学意义(Z=0.852,P=0.394);ATG7和AFP联合检测诊断HBV-HCC的AUC为0.859(95%CI:0.790~0.913),显著高于ATG7(Z=2.192,P=0.028)和AFP(Z=2.076,P=0.038)。结论ATG7是诊断HBV-HCC的良好标志物,ATG7和AFP联合检测可显著提高HBV-HCC的诊断率。

Objective To investigate the clinical significance of autophagy-related protein 7(ATG7)in the diagnosis of HBV-related hepatocellular carcinoma(HBV-HCC)by measuring the expression level of serum ATG7 in patients with HBV-HCC.Methods A total of 50 patients with chronic hepatitis B(CHB)and 89 patients with HCC who were hospitalized in Mengchao Hepatobiliary Hospital of Fujian Medical University from June 2018 to December 2020 were enrolled,among whom 67 patients had HBV-HCC(HBV-HCC group)and 22 patients had no HBV-HCC(non-HBV-HCC group),and 20 healthy volunteers who underwent physical examination were enrolled as healthy control(HC)group.Demographic data and laboratory data including alpha-fetoprotein(AFP)were collected from each group,and ELISA was used to measure the serum level of ATG7.The receiver operating curve(ROC)was plotted for ATG7 and AFP used alone or in combination,and the area under the ROC curve(AUC)was compared.The Kruskal-Wallis H test was used for comparison of non-normally distributed continuous data between multiple groups,and the Mann-Whitney U test was used for comparison between two groups;the chi-square test was used for comparison of categorical data between groups;a Spearman correlation analysis was used to investigate correlation.Results The serum level of ATG7 was 22.88(19.79-23.04)ng/mL in the HBV-HCC group,17.06(14.45-19.40)ng/mL in the non-HBV-HCC group,19.21(16.65-20.82)ng/mL in the CHB group,and 13.82(8.70-17.82)ng/mL in the HC group,with a significant difference between groups(χ^(2)=65.144,P<0.001).ATG7 had an AUC of 0.818(95%confidence interval[CI]:0.743-0.879)and AFP had an AUC of 0.777(95%CI:0.698-0.843)in the diagnosis of HBV-HCC,suggesting that ATG7 had a slightly higher AUC than AFP(Z=0.852,P=0.394).ATG7 combined with AFP had an AUC of 0.859(95%CI:0.790-0.913)in the diagnosis of HBV-HCC,which was significantly higher than the AUC of ATG7 alone(Z=2.192,P=0.028)and AFP alone(Z=2.076,P=0.038).Conclusion ATG7 is a good marker for the diagnosis of HBV-HCC,and combined measurement of ATG7 and AFP can significantly improve the diagnostic rate for HBV-HCC.
