Evaluation of PAGE-B Score for Hepatocellular Carcinoma Development in Chronic Hepatitis B Patients: Reliability, Validity, and Responsiveness.

Chronic hepatitis B (CHB) constitutes a major global public health issue, affecting millions of individuals. Despite the implementation of robust vaccination programs, the hepatitis B virus (HBV) significantly influences morbidity and mortality rates. CHB emerges as one of the leading causes of hepatocellular carcinoma (HCC), introducing a major challenge in the effective management of CHB patients. Therefore, it is of utmost clinical importance to diligently monitor individuals with CHB who are at high risk of HCC development. While various prognostic scores have been developed for surveillance and screening purposes, their accuracy in predicting HCC risk may be limited, particularly in patients under treatment with nucleos(t)ide analogues. The PAGE-B model, incorporating age, gender, and platelet count, has exhibited remarkable accuracy, validity, and reliability in predicting HCC occurrence among CHB patients receiving HBV treatment. Its predictive performance stands out, whether considered independently or in comparison to alternative HCC risk scoring systems. Furthermore, the introduction of targeted adjustments to the calculation of the PAGE-B score might have the potential to further improve its predictive accuracy. This review aims to evaluate the efficacy of the PAGE-B score as a dependable tool for accurate prediction of the development of HCC in CHB patients. The evidence discussed aims to provide valuable insights for guiding recommendations on HCC surveillance within this specific population.

Computed Tomography-Measured Liver Volume Predicts the Risk of Hepatocellular Carcinoma Development in Chronic Hepatitis C Patients

In this retrospective cohort study, we evaluated the significance of liver volume in the prediction of hepatocellular carcinoma (HCC) in 277 chronic hepatitis C (CHC) patients who received dynamic computed tomography (CT) during surveillance. Liver volumes were measured on portal venous phase of CT images by using ImageJ software. Liver volume index, a ratio of the standard liver volume expected by weight and height to the measured liver volume, was calculated to adjust for normal variations. The cohort was randomly divided to derivation (n = 100) and validation sets (n = 177) for the generation of a liver volume-based Cox prediction model and validation of a liver volume-based nomogram, respectively. The liver volume index was independent of weight or height, and it predicted further development of HCC (hazard ratio [HR] 16.30, 95% CI 6.70-39.62; p < 0.001). Liver cirrhosis, gamma-glutamyl transferase, and liver volume index were independent predictors of HCC, and nomogram-based prediction score from these three parameters identified high-risk patients at the cutoff of 110 in both derivation (p < 0.001) and validation cohort (p < 0.001). Liver volume-based prediction model stratifies the risk of developing HCC in CHC patients whose initial dynamic CT study gave negative results.

Risk of Hepatocellular Carcinoma Development in Chronic Hepatitis C Patients Who Achieved a Sustained Virological Response with Interferon-Based Treatments

Risk of Hepatocellular Carcinoma Development in Chronic Hepatitis C Patients Who Achieved a Sustained Virological Response with Interferon-Based Treatments

Impact of liver-stiffness measurement on hepatocellular carcinoma development in chronic hepatitis C patients treated with direct-acting antivirals: A systematic review and time-to-event meta-analysis.

Patients with chronic hepatitis C (CHC) treated with direct-acting antivirals (DAAs) are still at risk for developing hepatocellular carcinoma (HCC) even after achieving sustained virologic response (SVR). Liver-stiffness measurement (LSM) on imaging has been investigated as a predictor of HCC occurrence. To provide systematic summary of the predictive value of LSM in predicting HCC occurrence in HCV patients treated with DAA. A comprehensive literature search of the PubMed-MEDLINE and EMBASE databases was performed to identify studies that evaluated the predictive value of LSM in CHC patients treated with DAAs. Pooled hazard ratio (HR) comparing HCC occurrence between patients with positive and negative results on LSM was calculated for all studies and various subgroups. Subgroup analyses and meta-regression were performed. A review of 135 candidate articles identified eight eligible articles with a total of 3398patients for qualitative review and meta-analysis. The pooled HR for HCC occurrence determined by LSM was 3.43 (95% confidence interval [CI], 1.63-7.19) with heterogeneity (I2 =81.87%, P<0.001), thus indicating that LSM might be helpful for predicting HCC occurrence. In subgroup analyses, pooled HRs were different according to the study design (2.29; [95% CI, 0.96-5.45] for retrospective studies; 4.61 [95% CI, 2.44-8.71] for prospective studies), study population (4.00 [95% CI, 2.00-7.99] for CHC; 2.64 [0.99-7.00] for CHC with liver cirrhosis) and LSM parameter (3.17 [95% CI, 1.35-7.41] for baseline LSM; 4.19 [95% CI, 1.89-9.29] for others). In multivariate meta-regression, study design was the only influencing factor for pooled HR for HCC occurrence (P<0.05). Consistent evidence demonstrated the predictive value of LSM for HCC occurrence in CHC patients treated with DAA. The significant influencing factor for risk of HCC occurrence indicated by LSM was study design.

Chronic hepatitis B exhibited higher rate of hepatocellular carcinoma occurrence than hepatitis C in cirrhotic patients after effective antiviral treatment

Effective antiviral-therapy can reduce the risk of liver cirrhosis related hepatocellular carcinoma in patients with chronic hepatitis B and hepatitis C. Yet, the differenceof hepatocellular carcinoma development in chronic hepatitis B and hepatitis Cpatientswith cirrhosis after effective antiviral therapy treatment is unknown. In this study, We comprehensive explored the difference among them. 1363 patients with cirrhosis and hepatitis B virus treated with nucleos(t)ide analogues (NUCs) with completely suppressed virus, and patients with cirrhosis and hepatitis C virus treated with pegylated interferon (peg-IFN)/ribavirin (RBV) combination therapy who achieved sustained virologic response were enrolled. Total 261 developed hepatocellular carcinoma within a median follow-up of 4.25 years. Univariate analysis, patients developed hepatocellular carcinoma tended to be of older age, and had lower platelet counts, were chronic hepatitis B carriers, and had higher serum alfa-fetoprotein (AFP) (≥20ng/mL), FIB-4 index and APRI scores. Subsequent multivariate analysis revealed older age, lower platelet counts, high AFP levels andchronic hepatitis B carriers were independent risk factors of hepatocellular carcinoma. Our findings identify that chronic hepatitis B patients were with a higher risk of hepatocellular carcinoma compared to chronic hepatitis C patients after achieving virological response. Special attention should be paid to those patients.

Genetics Variants and Serum Levels of MHC Class I Chain-related A in Predicting Hepatocellular Carcinoma Development in Chronic Hepatitis C Patients Post Antiviral Treatment

Background/aimsThe genome-wide association study has shown that MHC class I chain-related A (MICA) genetic variants were associated with hepatitis C virus (HCC) related hepatocellular carcinoma. The impact of the genetic variants and its serum levels on post-treatment cohort is elusive. MethodsMICA rs2596542 genotype and serum MICA (sMICA) levels were evaluated in 705 patients receiving antiviral therapy. ResultsFifty-eight (8·2%) patients developed HCC, with a median follow-up period of 48·2months (range: 6–129months). The MICA A allele was associated with a significantly increased risk of HCC development in cirrhotic non-SVR patients but not in patients of non-cirrhotic and/or with SVR. For cirrhotic non-SVR patients, high sMICA levels (HR/CI: 5·93/1·86–26.38·61, P=0·002) and the MICA rs2596542 A allele (HR/CI: 4·37/1·52–12·07, P=0·002) were independently associated with HCC development. The risk A allele or GG genotype with sMICA>175ng/mL provided the best accuracy (79%) and a negative predictive value of 100% in predicting HCC. ConclusionsCirrhotic patients who carry MICA risk alleles and those without risk alleles but with high sMICA levels possessed the highest risk of HCC development once they failed antiviral therapy.

Prediction models of hepatocellular carcinoma development in chronic hepatitis B patients.

Chronic hepatitis B virus (HBV) infection is a major cause of cirrhosis and hepatocellular carcinoma (HCC). Applying the same strategies for antiviral therapy and HCC surveillance to all chronic hepatitis B (CHB) patients would be a burden worldwide. To properly manage CHB patients, it is necessary to identify and classify the risk for HCC development in such patients. Several HCC risk scores based on risk factors such as cirrhosis, age, male gender, and high viral load have been used, and have negative predictive values of ≥ 95%. Most of these have been derived from, and internally validated in, treatment-naïve Asian CHB patients. Herein, we summarized various HCC prediction models, including IPM (Individual Prediction Model), CU-HCC (Chinese University-HCC), GAG-HCC (Guide with Age, Gender, HBV DNA, Core Promoter Mutations and Cirrhosis-HCC), NGM-HCC (Nomogram-HCC), REACH-B (Risk Estimation for Hepatocellular Carcinoma in Chronic Hepatitis B), and Page-B score. To develop a noninvasive test of liver fibrosis, we also introduced a new scoring system that uses liver stiffness values from transient elastography, including an LSM (Liver Stiffness Measurement)-based model, LSM-HCC, and mREACH-B (modified REACH-B).

Wisteria floribunda agglutinin positive human Mac‐2‐binding protein as a predictor of hepatocellular carcinoma development in chronic hepatitis C patients

Wisteria floribunda agglutinin (WFA)-positive human Mac-2-binding protein (WFA(+) -M2BP) is a new glycol marker related to liver fibrosis. The aim of the present study was to evaluate WFA(+) -M2BP as a predictor of hepatocellular carcinoma (HCC) development in patients with chronic hepatitis C. This case-control study included 14 patients with chronic hepatitis C who developed HCC and 52controls, matched for age, gender, and fibrosis stage. WFA(+) -M2BP was measured at biopsy and follow-up. Time zero was set at the date of liver biopsy. WFA(+) -M2BP increased stepwise with progression of liver fibrosis (p < 0.001). Cumulative incidence of HCC development was significantly higher in patients with WFA(+) -M2BP ≥4.2 (p < 0.001) or in those with time-course changes in WFA(+) -M2BP (ΔWFA(+) -M2BP/year) ≥0.3 (p = 0.03). Multivariate analyses demonstrated that WFA(+) -M2BP ≥4.2 [hazard ratio (HR): 4.1, 95% confidence interval (CI): 1.1-15, p = 0.04], ΔWFA(+) -M2BP/year ≥0.3 (HR: 5.5, 95% CI: 1.5-19, p = 0.008), and AFP ≥10 ng/ml (HR: 4.7, 95% CI: 1.1-19, p = 0.03) were independent predictive factors of HCC development. Based on these data, we developed a simple scoring system to predict HCC development using these three factors. Using these scores, patients were classified into four groups; cumulative incidence of HCC development significantly increased with increasing scores (p < 0.001). WFA(+) -M2BP measurements and time-course changes in WFA(+) -M2BP can be used to identify patients at high risk of HCC development. Real-time monitoring of WFA(+) -M2BP can be a novel predictor of HCC development.

Clinical-guide risk prediction of hepatocellular carcinoma development in chronic hepatitis C patients after interferon-based therapy

Background:Interferon (IFN)-based therapies could eradicate hepatitis C (HCV) and reduce the risk of hepatocellular carcinoma (HCC). However, HCC could still happen after sustained virological response (SVR). We aimed to develop a simple scoring system to predict the risk of HCC development among HCV patients after antiviral therapies.Methods:From 1999 to 2009, 1879 patients with biopsy-proven HCV infection treated with IFN-based therapies were analyzed.Results:Multivariable analysis showed old age (adjusted HR (aHR)=1.73, 95% CI=1.13–2.65 for aged 60–69 and aHR=2.20, 95% CI=1.43–3.37 for aged ⩾70), Male gender (aHR=1.74, 95% CI=1.26–2.41), platelet count <150 × 109/l (HR=1.91, 95% CI=1.27–2.86), α-fetoprotein ⩾20 ng ml−1 (HR=2.23, 95% CI=1.58–3.14), high fibrotic stage (HR=3.32, 95% CI=2.10–5.22), HCV genotype 1b (HR=1.53, 95% CI=1.10–2.14), and non SVR (HR=2.40, 95% CI=1.70–3.38) were independent risk factors for HCC. Regression coefficients were used to build up a risk score and the accuracy was evaluated by using the area under the receiver operating characteristic curve (AUC). Three groups as low-, intermediate-, and high-risk are classified based on the risk scores. One hundred sixty patients (12.78%) in the derivation and 82 patients (13.08%) in the validation cohort developed HCC with AUC of 79.4%, sensitivity of 84.38%, and specificity of 60.66%. In the validation cohort, the 5-year HCC incidence was 1.81%, 12.92%, and 29.95% in low-, intermediate-, and high-risk groups, with hazard ratios 4.49 in intermediate- and 16.14 in high-risk group respectively. The risk reduction of HCC is greatest in patients with SVR, with a 5-year and 10-year risk reduction of 28.91% and 27.99% respectively.Conclusion:The risk scoring system is accurate in predicting HCC development for HCV patients after antiviral therapies.

Long‐term outcome and hepatocellular carcinoma development in chronic hepatitis B or cirrhosis patients after nucleoside analog treatment with entecavir or lamivudine

We conducted this prospective study to elucidate the long-term outcome and incidence of hepatocellular carcinoma (HCC) development after nucleos(t)ide analog (NA) treatment in patients with chronic hepatitis B (CHB) or cirrhosis. CHB or cirrhosis patients without past NA treatment or HCC were started on entecavir (ETV) or lamivudine (LVD), and prospectively followed up with monthly blood tests, and with abdominal imaging every 6 months in CHB and every 3 months in cirrhosis patients. A total of 256 subjects with CHB (n = 194) or cirrhosis (n = 62) received ETV (n = 129) or LVD (n = 127) for 4.25 years (range: 0.41-10.0). After NA treatment, serum HBV DNA, alanine aminotransferase and α-fetoprotein (AFP) dropped significantly, along with significant increases in serum albumin and prothrombin time. Drug-resistance developed in 60 cases in the LVD group and in only one case in the ETV group. HCC developed in 35 patients, and the incidence at years 1, 3, 5, 7 and 10 was significantly higher in patients with cirrhosis (8.1%, 17.5%, 43.2%, 46.7% and 53.4%, respectively) than chronic hepatitis (1.6%, 3.5%, 3.5%, 7.1% and 29.6%, respectively), with no difference between ETV and LVD. After NA treatment, the sensitivity/specificity for HCC of AFP and des-γ-carboxy prothrombin (DCP) was 45.7%/97.3% and 33.3%/96.2%, respectively, with the specificity of AFP being higher than at baseline (64.4%), at the cut-off of 10 ng/mL. NA exerted a long-term efficacy and improved hepatic reservation in CHB and cirrhosis. After NA treatment, AFP dropped to lower than 10 ng/mL with marked elevation of specificity, leading to an earlier detection of HCC.

Obesity Is an Independent Risk Factor for Hepatocellular Carcinoma Development in Chronic Hepatitis C Patients

It is not fully elucidated whether obesity enhances hepatocarcinogenesis in patients with chronic hepatitis C. The aim of this study was to investigate the relationship between body weight and risk of hepatocarcinogenesis in chronic hepatitis C patients. We enrolled 1431 patients with chronic hepatitis C who visited our liver clinic between 1994 and 2004, excluding those with hepatocellular carcinoma (HCC) at their visit or with a previous history of HCC. They were divided into 4 groups according to body mass index (BMI): underweight (< or =18.5 kg/m(2), N = 112); normal (18.5 to less than 25 kg/m(2), N = 1023); overweight (25 to less than 30 kg/m(2), N = 265); and obese (>30 kg/m(2), N = 31). We assessed the impact of obesity on the hepatocarcinogenesis adjusted by multivariate Cox proportional hazard regression with other risk factors found significant in univariate analysis. During the follow-up period (mean, 6.1 y), HCC developed in 340 patients, showing cumulative incidence rates of 10.5%, 19.7%, and 36.8% at 3, 5, and 10 years, respectively. The incidence differed significantly among the BMI groups (P = .007). Adjusting for other significant factors, overweight and obesity were shown to be an independent risk factor of HCC, with a hazard ratio of 1.86 (95% confidence interval, 1.09-3.16; P = .022) and 3.10 (95% confidence interval, 1.41-6.81; P = .005) as compared with the underweight patients. The risk of HCC in patients with chronic hepatitis C increases in proportion to BMI in a wide range of its values, from underweight to obese.

Hepatitis B virus gene in liver tissue promotes hepatocellular carcinoma development in chronic hepatitis C patients.

The hepatitis B virus (HBV) gene has been detected in hepatocellular carcinoma (HCC) tissue negative for the hepatitis B surface antigen and positive for the hepatitis C virus (HCV) antibody, but the precise role of the HBV gene in hepatocarcinogenesis has yet to be clarified. We studied the HBV gene in liver tissue several years before the emergence of HCC. Eleven patients diagnosed with HCV-positive chronic liver disease and who developed HCC were assigned to group A. HBV DNA was detected in 8 of the 11 patients (73%). Twenty-five patients, who did not develop HCC, were selected as group B. Six of the group B patients were classified as DNA-positive (24%). The HBV DNA in liver tissue was found to be significantly related to HCC development (P < 0.01). Thus, the presence of the HBV gene in patients with chronic HCV associated-liver injury appears to promote hepatocarcinogenesis, although prospective studies are needed to confirm this result.
