Efficacy of des-γ-carboxy-prothrombin in the diagnosis of hepatocellular carcinoma and its association with the clinical features of hepatocellular carcinoma
Journal Title: Journal of Clinical Hepatology - Year 2024, Vol 40, Issue 10
Abstract
[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<0.000 1）， 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.
