RESUMO
Objective To investigate the expression of multi-glycan in serum of patients with dual-phenotype hepatocellular (DPHCC) and its clinical significance. Methods Serum samples were collected from 65 patients with DPHCC, 80 patients with primary hepatocellular carcinoma (HCC), and 120 patients with liver cirrhosis (LC) who were treated in Mengchao Hepatobiliary Hospital of Fujian Medical University from June 2019 to December 2020. DNA sequencer-aided fluorophore-assisted carbohydrate electrophoresis was used to measure the expression of N-glycan in serum, The measurement data of normal distribution were compared by t -test between the two groups and analysis of variance between multiple groups; The measurement data with non normal distribution were compared by Mann-Whitney U test between the two groups and Kruskal-Wallis H test between multiple groups, the chi-square test was used for comparison of categorical data between groups.The logistic regression method was used to establish the common index model. The efficacy of AFP, PIVKA - Ⅱ, CEA, CA19-9 and multi glycan in the diagnosis of DPHCC was evaluated by receiver operating characteristic (ROC) curve, and the area under ROC curve (AUC) was compared by Z test. Results There was a significant difference in multi-glycan between the DPHCC group and the HCC group ( P < 0.001), while there were no significant differences in AFP, PIVKA-Ⅱ, CEA, CA19-9, and SUM between the two groups ( P =0.924, 0.084, 0.442, 0.924, and 0.206). Multi-glycan had an area under the ROC curve (AUC) of 0.775, which was significantly higher than that of AFP (0.507), PIVKA-Ⅱ (0.584), CEA (0.537), CA19-9 (0.505), and SUM (0.561), and multi-glycan had a sensitivity of 69.23%, which was increased compared with the other 5 items. There were significant differences in multi-glycan, AFP, PIVKA-Ⅱ, CA19-9, and SUM between the DPHCC group and the LC group (all P < 0.001), but there was no significant difference in CEA between the two groups ( P =0.14). Multi-glycan had an AUC of 0.780, which was also higher than that of AFP (0.767), PIVKA-Ⅱ (0.743), CEA (0.566), CA19-9 (0.689), and SUM (0.713), and multi-glycan had a sensitivity of 89.23%, which was increased compared with the other five items. Conclusion Multi-glycan can be used as one of the indicators for the auxiliary diagnosis of DPHCC.
RESUMO
Objective To explore the performance of serum AFP-L3 and PIVKA-Ⅱ in differential diagnosis of benign and malignant liver disease in high risk population.Methods The serum levels of AFP-L3 and PIVKA-Ⅱ in 48 patients with primary hepatic carcinoma,43 patients with cirrhosis and 81 patients with chronic hepatitis B were analyzed retrospectively.Results There was no statistically different significance among the median levels of serum AFP in primary hepatic carcinoma patients,cirrhosis patients and chronic hepatitis B patients (x2=4.014,P=0.134).Both median level of AFP-L3 and PIVKA-Ⅱ in primary hepatic carcinoma patients were higher than cirrhosis patients and chronic hepatitis B patients (x2 =33.93,52.33,both of P values were below 0.001).The specificity (92.74％) of AFP-L3 and the sensitivity (79.17％) of PIVKA-Ⅱ were all higher.The accuracy (84.88％) of combined detection in series was the highest,with its 47.92％ of sensitivity and 99.19％ of specificity.Conclusion Combined detection PIVKA-Ⅱ and AFP-L3 series will help to differential diagnosis of benign and malignant liver disease in high risk population.
RESUMO
Objective To discuss the clinical value of protein induced by vitaminK absence antagonist-Ⅱ (PIVKA-Ⅱ)and al-pha-fetoprotein (AFP)in diagnosing primary hepatocellular carcinoma (PHC).Methods There were 178 samples from in-patients in Fuzhou Infectious Disease Hospital,including 54 patients with PHC,39 patients with liver cirrhosis,55 patients with hepatitis and 30 cases of healthy.Serum levels of PIVKA-II and AFP levels were detected by LUMI-PULSEG1200 au-tomatic immunity analyzer and Abbott automatic immunity analyzer respectively,and the difference between the levels was compared.Analyzed the areas under the receiver operating characteristic curves (ROC-AUC)and compared the sensitivity and specificity of single PIVKA-II or AFP assay,and the combined detection of PHC.Results The serum level of PIVKA-Ⅱ in hepatocellular carcinoma group was 274 mAU/ml,which was higher than that in liver cirrhosis group (23 mAU/ml), chronic hepatitis group (26 mAU/ml)and healthy group (21 mAU/ml)(P<0.001),and the levels of AFP in PHC group was 84.0 ng/ml,which was higher than that in liver cirrhosis (21.78 ng/ml)and healthy groups (2.8 ng/ml).But it was not statistically significant (P=0.585)compared with those in the chronic hepatitis group (66.8 ng/ml),the results of re-ceiver operating characteristic (ROC)curve showed that the area under the curve of PIVKA-Ⅱ was 0.776,higher than the AFP (0.649),(Z=2.262,P=0.023 7).Serum PIVKA-Ⅱ (≥40 mAU/ml)had a sensitivity of 78.52% and a specificity of 76.23% in the diagnosis of PHC,While serum AFP (≥10 mg/ml)had a sensitivity of 77.78% and a specificity of 34.64%in the diagnosis of PHC.A combination of serum levels of PIVKA-Ⅱ and AFP could increase the sensitivity in the diagnosis of PHC (vs PIVKA-Ⅱ,P=0.031;vs AFP,P=0.016)and specificity (vs PIVKA-Ⅱ,P=0.004;vs AFP,P=0.001).Con-clusion Serum PIVKA-Ⅱ have high clinical application values in diagnosing PHC.A combination of serum levels of PIV-KA-Ⅱ and AFP could increase the sensitivity and specificity in diagnosis of PHC.
