摘要
目的评估异常凝血酶原(DCP)在肝细胞癌(HCC)临床应用中的价值。方法回顾性分析2020年1月—2021年7月吉林大学第一医院收治的179例HCC患者的临床资料,另纳入207例健康对照者。应用磁微粒化学发光免疫分析法测定AFP及DCP血清学水平。绘制单独及联合检测时的受试者工作特征曲线(ROC曲线),并计算曲线下面积(AUC),探究联合应用DCP及AFP相较于单独检测AFP对HCC的临床诊断价值,以及DCP对AFP阴性患者的诊断效能。不符合正态分布的计量资料组间比较采用Mann-Whitney U检验。通过ROC曲线分析评估诊断效率。通过Spearman相关性分析明确肿瘤标志物与HCC病理学特征的相关性。结果HCC患者血清AFP和DCP水平较正常患者显著升高(Z值分别为-9.562、-11.678,P值均<0.05),DCP和AFP的联合检测优于AFP单独检测(Z=5.309,P<0.01)。DCP存在对AFP阴性HCC患者的诊断能力(AUC=0.789,P<0.0001),敏感度和特异度分别为61.64%和86.47%。血清DCP水平与肿瘤大小(r=0.546,P<0.001)、TNM分期(r=0.306,P<0.001)、微血管侵犯(r=0.358,P<0.001)呈正相关,与肿瘤分化程度呈负相关(r=-0.220,P<0.05)。结论AFP、DCP的联合检测可提高HCC检出率且DCP可用于AFP阴性HCC患者的补充筛查;DCP的表达水平与HCC临床病理特征(包括肿瘤大小、TNM分期、微血管侵犯、肿瘤分化程度)之间存在相关性。
Objective To investigate the value of des-γ-carboxy-prothrombin(DCP)in hepatocellular carcinoma(HCC).Methods A retrospective analysis was performed for the clinical data of 179 HCC patients who were admitted to The First Hospital of Jilin University from January 2020 to July 2021,and 207 healthy controls were enrolled as normal group.Magnetic particle chemiluminescence immunoassay was used to measure the serological levels of alpha-fetoprotein(AFP)and DCP.The receiver operating characteristic(ROC)curve was plotted for each indicator measured alone or in combination,and the area under the ROC curve(AUC)was calculated to investigate the value of DCP combined with AFP versus AFP alone in the diagnosis of HCC and the diagnostic efficacy of DCP in AFP-negative patients.The Mann-Whitney U test was used for comparison of non-normally distributed continuous data between groups;the ROC curve was used to evaluate diagnostic efficiency;the Spearman correlation analysis was used to investigate the correlation of tumor markers with the pathological features of HCC.Results The patients with HCC had significantly higher serum levels of AFP and DCP than the normal group(Z=−9.562 and−11.678,P<0.05),and combined measurement of DCP and AFP had a better value than AFP measured alone(Z=5.309,P<0.01).DCP had certain capability in the diagnosis of AFP-negative HCC patients,with an AUC of 0.789(P<0.0001),a sensitivity of 61.64%,and a specificity of 86.47%.Serum DCP level was positively correlated with tumor size(r=0.546,P<0.001),TNM stage(r=0.306,P<0.001),and microvascular invasion(r=0.358,P<0.001)and was negatively correlated with the degree of tumor differentiation(r=−0.220,P<0.05).Conclusions The combined measurement of AFP and DCP can improve the detection rate of HCC,and DCP can be used for supplementary screening in AFP-negative HCC patients.The expression level of DCP is correlated with the clinicopathological features of HCC,including tumor size,TNM stage,microvascular invasion,and the degree of tumor differentiation.
