RESUMEN
Hepatic stellate cells (HSCs) are responsible for liver fibrosis accompanied by its activation into myofibroblasts and the abundant production of extracellular matrix. However, the HSC contribution to progression of liver inflammation has been less known. We aimed to elucidate the mechanism in HSCs underlying the inflammatory response and the function of tumor necrosis factor α-related protein A20 (TNFAIP3). We established A20 conditional knockout (KO) mice crossing Twist2-Cre and A20 floxed mice. Using these mice, the effect of A20 was analyzed in mouse liver and HSCs. The human HSC line LX-2 was also used to examine the role and underlying molecular mechanism of A20. In this KO model, A20 was deficient in >80% of HSCs. Spontaneous inflammation with mild fibrosis was found in the liver of the mouse model without any exogenous agents, suggesting that A20 in HSCs suppresses chronic hepatitis. Comprehensive RNA sequence analysis revealed that A20-deficient HSCs exhibited an inflammatory phenotype and abnormally expressed chemokines. A20 suppressed JNK pathway activation in HSCs. Loss of A20 function in LX-2 cells also induced excessive chemokine expression, mimicking A20-deficient HSCs. A20 overexpression suppressed chemokine expression in LX-2. In addition, we identified DCLK1 in the genes regulated by A20. DCLK1 activated the JNK pathway and upregulates chemokine expression. DCLK1 inhibition significantly decreased chemokine induction by A20-silencing, suggesting that A20 controlled chemokine expression in HSCs via the DCLK1-JNK pathway. In conclusion, A20 suppresses chemokine induction dependent on the DCLK1-JNK signaling pathway. These findings demonstrate the therapeutic potential of A20 and the DCLK1-JNK pathway for the regulation of inflammation in chronic hepatitis.

AIM: Gamma-glutamyltransferase (GGT) is known as an oxidative stress marker, induced by alcohol consumption and metabolic disorders, and is reported as a predictor of hepatocellular carcinoma (HCC) development after hepatitis C virus (HCV) elimination. However, it is not clear whether GGT serves simply as a surrogate marker for overlapping metabolic diseases or reflects HCV-specific carcinogenicity. We investigated the association between GGT and hepatocarcinogenesis after achieving a sustained viral response (SVR), accounting for drinking habits or diabetes, and examined predisposing factors associated with GGT levels after SVR. METHODS: This is a prospective, multicenter, and observational study using the database of 1001 patients after HCV eradication with direct-acting antiviral agents. The association of GGT at SVR with cumulative HCC development was examined in a multivariate analysis using Cox proportional hazard models after adjustment for covariates including alcohol and diabetes. The association between oxidative stress markers or genetic factors and GGT levels was analyzed. RESULTS: High GGT levels at SVR were associated with HCC development (HR] 2.38, 95% CI 1.10-5.17). This association was also significant when restricted to patients without alcohol consumption or diabetes (HR 8.38, 95% CI 2.87-24.47). GGT levels were correlated with serum growth differentiation factor 15 levels, a marker of mitochondrial dysfunction. Single-nucleotide polymorphisms of ZNF827 and GDF15 were associated with high GGT levels. CONCLUSIONS: High GGT levels at SVR were associated with HCC development after accounting for alcohol consumption and diabetes. GGT levels are influenced by genetic predisposition and may reflect mitochondrial dysfunction after HCV eradication.
RESUMEN
AIM: C-reactive protein (CRP) is both an inflammatory and prognostic marker in various cancers. This study aimed to elucidate the characteristics of CRP and the prognostic factors in patients who were administered with atezolizumab plus bevacizumab (ATZ + BEV) for unresectable hepatocellular carcinoma (HCC). METHODS: A total of 213 patients who received ATZ + BEV for HCC from November 2020 to March 2023 at 15 hospitals were enrolled in this retrospective study. The prognosis was analyzed by subdividing the patients based on baseline characteristics, radiologic response, and treatment lines. Accuracy of survival prediction was assessed using CRP, alpha fetoprotein (AFP), C-reactive protein and alpha fetoprotein in immunotherapy (CRAFITY), and Glasgow Prognostic Score. RESULTS: Compared with patients with baseline CRP <1 mg/dL, those with baseline CRP ≥1 mg/dL (n = 45) had a significantly higher baseline albumin-bilirubin score and AFP levels, significantly lower disease control rate (62.2%), and significantly shorter median overall survival (hazards ratios 2.292; 95% confidence interval 1.313-5.107; log-rank test, p < 0.001). Multivariate analysis identified CRP ≥1 mg/dL, AFP ≥100 ng/mL, and modified albumin-bilirubin grade as the significant prognostic factors. The baseline CRP, AFP, CRAFITY, and Glasgow Prognostic Score demonstrated higher discrimination for 1-year survival prediction after first-line ATZ + BEV administration, compared with beyond second line, with area under the receiver operating characteristic curves of 0.759, 0.761, 0.805, and 0.717, respectively. CONCLUSIONS: CRP was a significant biomarker in patients treated with ATZ + BEV for HCC. Elevated CRP levels may indicate aggressive cancer progression and potential resistance to ATZ + BEV therapy.
RESUMEN
The number of patients with fatty liver has been increasing worldwide; however, the significance of fatty liver in patients with chronic hepatitis B who are receiving nucleic acid analog (NA) therapy remains unclear. Thus, we aimed to determine whether fatty liver affects the development of hepatocellular carcinoma (HCC) in patients receiving NA therapy. This study included 445 patients who received NA therapy, and the development of HCC was investigated. The primary outcome was the association between fatty liver and HCC development. During a mean follow-up period of 7.4 years, 46 patients (10.3%) developed HCC. No significant difference in the cumulative incidence of HCC was observed between patients with fatty liver and those without (p = 0.17). Multivariable analysis for age, gender, platelet count, alanine aminotransferase level at 1 year following NA therapy, and fatty liver revealed that the presence of fatty liver was not a significant factor for HCC development (hazard ratio [HR]: 0.96, 95% confidence interval [CI]: 0.5-1.9). In another multivariable analysis for advanced fibrosis, gender, and fatty liver, advanced fibrosis was found to be a significant factor for HCC development (HR: 9.50, 95% CI: 5.1-18) but not fatty liver (HR: 0.90, 95% CI: 0.5-1.7). In conclusion, in patients with chronic hepatitis B who received NA therapy, advanced fibrosis was found to be an important risk factor for HCC development but not fatty liver, suggesting the importance of providing treatment before the progression of liver fibrosis regardless of the presence of fatty liver.

AIM: Alanine aminotransferase (ALT) is a criterion for the introduction of nucleotide/nucleoside analog (NA), and ALT levels are decreased by NA treatment. However, the association between post-treatment ALT levels and hepatocellular carcinoma (HCC) risk remains unclear. To fill this gap, we aimed to establish a target value of ALT level during NA treatment. METHODS: In total, 413 patients with chronic hepatitis B who received entecavir, tenofovir alafenamide, or tenofovir disoproxil fumarate were enrolled. The subsequent development of HCC was examined and a target value of ALT level during NA treatment as a risk marker for HCC was evaluated. RESULTS: The median follow-up duration was 5.1 years, during which time 27 patients (8.6%) developed HCC. ALT level at the start of treatment was not associated with HCC development (p = 0.08). When stratified by ALT at 1 year after NA initiation, the cumulative 3- and 5-year rates of HCC for patients with ALT ≥21 IU/L were 11.5% and 18.1%, and those with ALT <21 IU/L was 2.3% and 6.5%, respectively. Patients with ALT <21 IU/L had a significantly lower risk of HCC development compared with patients with ALT ≥21 IU/L (p = 0.002). In multivariable analysis adjusting age, sex, and platelet counts, ALT ≥21 IU/L was an independent risk factor of HCC development with hazard ratio of 4.5 (95% confidence interval: 1.01-20.4). CONCLUSIONS: ALT <21 IU/L at 1 year after NA initiation has a lower risk of HCC and could be used as a target value for NA treatment.
RESUMEN
BACKGROUND: We aimed to investigate the efficacy and safety of atezolizumab plus bevacizumab therapy in patients with unresectable hepatocellular carcinoma (u-HCC) based on whether they had previously received systemic therapy, as well as the association of atezolizumab plus bevacizumab with early alpha-fetoprotein (AFP) response in real-world practice. METHODS: A total of 52 patients with u-HCC were treated with atezolizumab plus bevacizumab between October 2020 and April 2021. The Response Evaluation Criteria in Solid Tumors (RECIST) and modified RECIST were used to evaluate radiological responses. RESULTS: The patients received atezolizumab plus bevacizumab as 1st-line (n = 23), 2nd-line (n = 16), 3rd-line (n = 6), 4th-line (n = 3), 5th-line (n = 3), or 6th-line (n = 1) therapy. According to RECIST, the objective response rate (ORR) and disease control rate (DCR) in all patients were 15.4% and 57.7%. In the 1st-line patients, ORR and DCR based on RECIST 1.1 were 27.3% and 81.8%. The median time to progression (TTP) assessed by RECIST was significantly longer among patients receiving atezolizumab plus bevacizumab as 1st-line therapy than in patients receiving atezolizumab plus bevacizumab as later-line therapy (P < 0.001). Patients with an AFP response (reduction ≥ 20% from baseline) at 6 weeks had a significantly longer TTP assessed by RECIST than those without an AFP response (P = 0.02). CONCLUSION: Patients who received atezolizumab plus bevacizumab as 1st-line therapy had better clinical outcome than those who received atezolizumab plus bevacizumab in later lines. The AFP response at 6 weeks could be a predictor of disease progression.

BACKGROUND AND AIMS: A retrospective study was to analyze the association of plasma renin activity (PRA) with overall survival and liver disease-related events in decompensated liver cirrhosis with ascites treated by tolvaptan. METHODS: We included 196 patients with decompensated cirrhosis treated with tolvaptan and for whom hepatic ascites had remained uncontrolled by conventional diuretics. Factors associated with prognosis and appearance of liver disease-related events were investigated, including vasopressin, sympathetic nervous system hormones (adrenaline, noradrenaline, and dopamine), and the renin-angiotensin system (PRA and aldosterone) at the beginning of tolvaptan treatment. RESULTS: Age, history of hepatocellular carcinoma (HCC), and PRA were identified as independent factors for prognosis after tolvaptan treatment. The median survival time in patients with PRA ≥9.5 ng/mL/h at the beginning of tolvaptan treatment was significantly shorter than in patients with PRA <9.5 ng/mL/h (193 vs. 893 days, p < 0.001). PRA and a history of HCC were independent factors for the occurrence of liver disease-related events. The median event-free period in patients with PRA ≥3.2 ng/mL/h was significantly shorter than that of patients with PRA <3.2 ng/mL/h (89 vs. 222 days, p < 0.001). CONCLUSIONS: PRA is an independent predictor of prognosis and appearance of liver disease-related events in patients with decompensated cirrhosis who have started tolvaptan treatment.

BACKGROUND AND AIM: MEFIB (the combination of magnetic resonance elastography [MRE] ≥ 3.3 kPa and fibrosis-4 (FIB-4) ≥ 1.6) is useful for detecting patients with significant fibrosis (fibrosis stage ≥ 2) having nonalcoholic fatty liver disease (NAFLD). However, age-dependent thresholds of FIB-4 have been proposed, and it remains unclear whether MEFIB could be applied with the same FIB-4 threshold in a different cohort. Therefore, in this study, we examined the best threshold of FIB-4 and validated the utility of MEFIB. METHODS: This study included 105 biopsy-proven NAFLD patients with contemporaneous MRE assessment. The primary outcome was a diagnostic accuracy for significant fibrosis. RESULTS: The median (interquartile range) age was 65 (58-72) years, and significant fibrosis was 76.2% (80/105). FIB-4 of 2.1 was defined as the best threshold for significant fibrosis in the cohort. The area under the receiver operating characteristics curves (AUROCs) of the combination of MRE and FIB-4 (MRE ≥ 3.3 kPa + FIB-4 ≥ 1.6: 0.80, MRE ≥ 3.3 kPa + FIB-4 ≥ 2.1: 0.84) were higher than those of each index alone (MRE ≥ 3.3 kPa: 0.76, FIB-4 ≥ 1.6: 0.72, and FIB-4 ≥ 2.1: 0.77), but AUROCs of MRE ≥ 3.3 kPa + FIB-4 ≥ 1.6 and MRE ≥ 3.3 kPa + FIB-4 ≥ 2.1 were equivalent (P = 0.3). CONCLUSIONS: MEFIB is useful for detecting patients with significant fibrosis and could be utilized in a different cohort without changing the threshold of FIB-4, and it may then be used as a two-step screening strategy.

Carcinogenesis risk scores for chronic hepatitis B have been proposed, but it remains unclear whether these scores during nucleoside/nucleotide analogue (NA) therapy are useful for risk assessment. In this study, we examined changes of these scores and the predictability during NA treatment. 432 patients with no history of hepatocellular carcinoma (HCC) treated with NA were enrolled. PAGE-B, modified PAGE-B (mPAGE-B), and REACH-B scores were calculated at NA administration, 1 and 2 years after administration. The median follow-up duration was 5.1 years, during which 37 patients (8.6%) developed HCC. Cumulative incidence HCC development in patients with high risk of PAGE at NA administration, and 1 and 2 years after NA administration was significantly higher than those with intermediate and low-risk groups (p < .05 for all time points), whereas HCC incidence in patients with high risk of mPAGE-B and REACH-B at 2 years after NA administration were equivalent to those with intermediate and low-risk groups (p = .2 for mPAGE-B, and p = .1 for REACH-B). The area under the receiver operating characteristic (AUROC) for HCC development of PAGE-B at NA administration, and 1 and 2 years after administration were 0.773, 0.803 and 0.737, respectively. The AUROCs of PAGE-B at each point were continuously higher than those of REACH-B (0.646, 0.725, and 0.653, respectively) and mPAGE-B (0.754, 0.734, and 0.678, respectively).PAGE-B score has a high diagnostic accuracy for HCC development at any time point during NA treatment, indicating its potential use as a real-time monitor of HCC development.

Almost all patients achieved sustained virological response (SVR) by direct-acting antivirals (DAA) therapy, but it is not clear as to what extent DAA therapy affects changes in liver fibrosis after achieving SVR. In this study, we investigated the changes of liver stiffness by magnetic resonance elastogaraphy (MRE) during DAA therapy. A total of 308 patients were enrolled in the study. Liver stiffness was measured twice before and after DAA treatment using MRE and time-course change of liver stiffness was investigated. The median (interquartile range) values for liver stiffness were 4.2 (3.2-6.1) kPa at baseline and 3.3 (2.6-4.8) kPa at SVR, demonstrating a significant improvement (p < .01). A total of 44% of patients had no improvement in liver stiffness despite achieving SVR. In patients with advanced fibrosis (lower level of albumin [Alb] or histological fibrosis stage F4), it was difficult to improve liver stiffness. Except for Alb, there were no blood tests associated with nonimprovement in liver stiffness, making these cases difficult to predict. In conclusion, despite obtaining SVR, improvement in liver stiffness could not be obtained in some cases, especially in patients with advanced fibrosis. In these patients, liver stiffness must be followed even if SVR is obtained.

AIM: Intrahepatic cholangiocarcinoma (ICC) is a highly aggressive malignancy. However, the characteristics and prognosis of ICC is not well known. This study aims to reveal the relationship between liver function and prognosis of ICC. METHODS: A total of 83 ICC patients were recruited retrospectively from March 2009 to August 2020. Child-Pugh (CP) and albumin-bilirubin (ALBI) scores were used to assess liver function. The extent of portal vein tumor thrombosis (PVTT) was classified from Vp0 to Vp4. The end-point for this analysis was overall survival (OS). RESULTS: The median age was 72 (44-88) years, 48 patients were male (57.8%), and 70 patients were classified as CP grade A (84.3%). At baseline, chronic liver disease (hepatitis B, 9.6%; hepatitis C, 15.7%; alcoholic liver disease, 9.6%; and nonalcoholic fatty liver disease, 4.8%) were diagnosed. The median OS of all ICC patients was 21.2 months. A total of 27 patients underwent surgical resection; these patients showed a longer median OS compared to those who did not undergo surgery (50.8 months vs. 5.5 months, p < 0.001). The prognosis of patients with ICC can be stratified by ALBI grade (grade 1, 54.3 months; grade 2a, 8.4 months; grade 2b, 3.9 months; and grade 3, 1.4 months; p < 0.001) and the extent of PVTT (Vp0, 54.3 months; Vp1/2, 8.4 months; and Vp3/4, 3.9 months; p = 0.0039). CONCLUSION: In this study, viral hepatitis (25.3%) was identified as the most prevalent background liver disease of ICC. Assessing liver function using ALBI grade is useful for stratifying the prognosis of patients with ICC.
RESUMEN
BACKGROUND AND AIM: The serum hepatitis B core-related antigen (HBcrAg) is considered a surrogate marker of the amount and activity of intrahepatic covalently closed circular DNA. This study aims to investigate the virological characteristics of HBcrAg in chronic hepatitis B (CHB) patients and to reveal the hepatocellular carcinoma (HCC) risk factors of hepatitis B e antigen (HBeAg)-negative patients. METHODS: Hepatitis B core-related antigen was measured in 245 naive CHB patients before receiving nucleoside/nucleotide analog (NA) therapy. All patients were receiving NA (entecavir, tenofovir disoproxil fumarate, and tenofovir alafenamide) continuously for more than 1 year until the end of follow-up, and they did not have a history of HCC. Hepatitis B viral status was compared between 106 HBeAg-positive and 139 HBeAg-negative patients. RESULTS: Median HBcrAg levels were significantly higher in HBeAg-positive patients than in HBeAg-negative patients (> 6.8 vs 3.7 log U/mL, P < 0.01). In HBeAg-negative patients, higher HBcrAg levels were associated with cirrhosis (119 chronic hepatitis/20 cirrhosis = 3.5/4.7 log U/mL, P = 0.03) and higher serum hepatitis B virus DNA. During a median follow-up of 5.28 (1.03-12.0) years, the 5-year cumulative HCC incidence rate was 5.4% in the HBeAg-negative cohort. In the multivariate Cox regression analysis, higher HBcrAg levels at 1 year were independent predictive factors for HCC development in HBeAg-negative patients who received NA therapy (cutoff value, 4.1 log U/mL; hazard ratio, 6.749; 95% confidence interval, 1.334-34.15, P < 0.01) and even in non-cirrhosis patients. CONCLUSION: Hepatitis B core-related antigen was useful for understanding disease progression in CHB patients and for stratifying the risk for carcinogenesis in HBeAg-negative patients receiving NA therapy.

BACKGROUND AND AIM: The association between liver fibrosis, fatty liver, and cardiovascular disease (CVD) risk is unknown. Hence, this study aimed to investigate the association of liver fibrosis and fatty liver with CVD risk independent of already known CVD risk comorbidities. METHODS: This is a prospective study registered with the University Hospital Medical Information Network clinical trial registry (UMIN000036175). Liver fibrosis was assessed by serum fibrosis markers including FIB-4, nonalcoholic fatty liver disease fibrosis score (NFS), and Wisteria floribunda agglutinin-positive Mac-2 binding protein (WFA+ -M2BP), whereas fatty liver was diagnosed by ultrasonography. CVD risk was evaluated using the Framingham risk score (FRS), and a high CVD risk was defined as an FRS ≥ 20%. RESULTS: A total of 3512 subjects were enrolled, and high CVD risk (FRS ≥ 20%) was observed in 17.5%. Advanced fibrosis (FIB-4 ≥ 2.67, NFS ≥ 0.675, and WFA+ -M2BP ≥ 1.0) and the presence of fatty liver were significantly associated with high CVD risk independent of diabetes mellitus, dyslipidemia, and hypertension. When subjects were stratified by liver fibrosis and fatty liver, subjects with advanced fibrosis and fatty liver have the highest odds for high CVD risk (odds ratio [OR]: 5.90-35.6), followed by subjects with advanced fibrosis and without fatty liver (OR: 2.53-9.62) using subjects without advanced fibrosis and fatty liver as a reference. CONCLUSIONS: Liver fibrosis and fatty liver were associated with CVD risk independent of already known CVD risk comorbidities. The assessment of liver fibrosis and fatty liver may be useful to identify high CVD risk subjects.

Adherence to nucleotide/nucleoside analog therapy is important in improving prognosis in chronic hepatitis B. We aimed to compare medical adherence and satisfaction with entecavir (ETV) and tenofovir alafenamide (TAF) and to assess the effect of switching from ETV to TAF. Patients taking ETV (n = 114) and TAF (n = 35), and who switched from ETV to TAF (n = 15) were included. Medication adherence and satisfaction were assessed using a questionnaire. There was no significant difference in adherence between the ETV and TAF groups, but the medication satisfaction rates (0-10, prefer-dislike) were 1.72 ± 2.2 and 0.69 ± 1.5, respectively (P = .01; significantly higher in the TAF group). In patients who switched from ETV to TAF, medication adherence significantly improved (P = .04) as follows: never forgetting, from 40% to 87%; forgetting once every 2 to 3 months, from 33% to 7%; forgetting once every 2 months, from 20% to 7%, and forgetting once every 4 weeks, from 7% to 0%. Similarly, the medication satisfaction rate significantly improved from 4.53 ± 3.2 to 1.27 ± 2.4 after switching (P = .008). In conclusion, switching from ETV to TAF can be a useful approach to improve medication adherence and satisfaction.

AIM: Tyrosine kinase inhibitor (TKI) therapy resulted in better prognosis for patients with hepatocellular carcinoma (HCC). However, some cases with Barcelona Clinic Liver Cancer (BCLC) stage C disease still had poor prognosis. This study aimed to investigate prognosis and characteristics of patients with HCC treated with TKI based on liver function and the extent of portal vein tumor thrombosis (PVTT). METHODS: Patients receiving TKI therapy (n = 345) were recruited retrospectively. Child-Pugh score and albumin-bilirubin (ALBI) score were used for assessment of liver function. The extent of PVTT was classified from Vp0 to Vp4. Radiotherapy or hepatic arterial infusion chemotherapy were carried out as additional therapy to TKI. The end-point for this analysis was overall survival (OS). RESULTS: A total of 291 and 54 patients received sorafenib and lenvatinib as first-line TKI therapy, respectively. The median OS of patients treated with TKI were significantly stratified by ALBI grade (grade 1, 20.1 months; grade 2a, 16.3 months; grades 2b and 3, 9.8 months; P = 0.0003). The classification of PVTT significantly stratified the prognosis of patients treated with TKI (median OS: Vp0, 18.5 months; Vp1/2, 14.4 months; Vp3/4, 5.5 months; P < 0.0001). In the ALBI 2b/3 and Vp3/4 groups, the median OS of patients treated with TKI and additional therapies was significantly longer than those treated with TKI only (9.2 months vs.. 3.6 months; P = 0.0129). CONCLUSION: Liver function and PVTT are useful for stratifying prognosis of HCC patients treated with TKI. The applicative classification could lead to appropriate therapy and better prognosis.
RESUMEN
AIM: The albumin, bilirubin, and platelet (ABP) criteria was proposed to avoid screening endoscopy for detecting high-risk varices (HRV) and it has high diagnostic accuracy. We carried out a retrospective cross-sectional study to verify the diagnostic accuracy. METHODS: A total of 610 patients with advanced fibrosis were enrolled in the study. ABP criteria are defined as follows: albumin >4.0 g/dL, bilirubin <22 µmol/L, and platelets >114 000/µL. RESULTS: Background liver disease were hepatitis C/hepatitis B/non-alcoholic fatty liver disease/others:405 (66.4%)/67 (10.5%)/78 (12.8%)/60 (10.3%). A total of 105 patients (17.2%) had HRV. In multivariate analysis, serum bilirubin <22 µmol/L (HR 2.00, 95% CI 1.2-3.4), albumin >4.0 g/dL (HR 2.56, 95% CI 1.7-3.8), and platelets >114 000/µL (HR 3.52, 95% CI 2.1-5.8) levels were independently associated with no presence of HRV. When the ABP criteria were examined, 200 patients (32.8%) fulfilled the criteria, and 194 patients had no HRV (positive predictive value 97.0%) When classified by etiologies (hepatitis C/hepatitis B/non-alcoholic fatty liver disease), positive predictive value were 97.7/100/92.0%, respectively. CONCLUSIONS: The ABP criteria are easy to examine, because they use only standard laboratory tests, and they are available for screening patients who might avoid endoscopy regardless of etiologies.
RESUMEN
AIM: Lenvatinib (LEN) is a newly approved, multikinase inhibitor for treating unresectable hepatocellular carcinoma. In the present study, we investigated the impact of three different criteria for evaluating radiological objective response (OR) on overall survival in real-world data. METHODS: Consent for LEN therapy was obtained from 51 patients from April 2018 to March 2019. A total of 40 patients who received a minimal cumulative duration of 4 weeks of LEN were included in the analysis. Enhanced computed tomography scan was performed at baseline and every 4-8 weeks after LEN administration. Overall survival and OR were assessed with three different evaluations, as follows: Response Evaluation Criteria in Solid Tumors 1.1, modified Response Evaluation Criteria in Solid Tumors, and Choi criteria. RESULTS: The average observation period for all participants after LEN introduction was 209.4 ± 77.5 days. The Response Evaluation Criteria in Solid Tumors 1.1, modified Response Evaluation Criteria in Solid Tumors, and Choi criteria identified 10 of 40 (25.0%), 15 of 40 (37.5%), and 18of 40 (45.0%) patients with OR, respectively. The median overall survival in progressive disease evaluated by each criterion was 227 days. This result was significantly shorter than OR. Furthermore, the cumulative duration of LEN administration (>150 days) represented a significant prognostic factor (HR 0.160. 95% CI 0.039-0.646, P = 0.001). CONCLUSION: The Response Evaluation Criteria in Solid Tumors 1.1, modified Response Evaluation Criteria in Solid Tumors, and Choi criteria were useful therapeutic evaluation methods in LEN therapy for unresectable hepatocellular carcinoma. LEN's appropriate effect evaluation and management might lead to a better prognosis.
RESUMEN
BACKGROUND AND AIM: The prediction of hepatocellular carcinoma (HCC) development during nucleotide/nucleoside analog (NA) therapy is clinically important in patients with chronic hepatitis B. Although several useful models for HCC prediction have been previously reported, their usefulness in the Japanese population is unclear. Therefore, this study examines the applicability of these models in Japanese patients. METHODS: Four hundred forty-three patients with no history of HCC who were treated with entecavir, tenofovir alafenamide, or tenofovir disoproxil fumarate were enrolled. PAGE-B, modified-PAGE-B, and REACH-B scores were calculated, and subsequent HCC development was investigated. RESULTS: The mean follow-up duration was 5.1 years, and a total of 33 patients (7.4%) developed HCC during the follow-up period. Multivariate analysis revealed that old age (hazard ratio [HR] 1.05, 95% confidence interval [CI] 1.01-1.09, P = 0.011), male gender (HR 2.62, 95% CI 1.06-6.49, P = 0.037), and low platelet count (HR 0.83, 95% CI 0.77-0.91, P < 0.001) were independent predictors of HCC development. These factors are the same as the factors identified in the PAGE-B model. Time-dependent area under the receiver operating characteristic (AUROC) curve revealed that the AUROCs for 3 and 7 years of PAGE-B (AUROC: 0.786 and 0.744 at 3 and 7 years, respectively) were continuously higher than those of REACH-B (0.658 and 0.543) and modified PAGE-B AUROC (0.772 and 0.731). CONCLUSIONS: PAGE-B, which can easily identify high-risk cases, can be useful for predicting HCC development in Japanese patients treated with NA therapy.

Chronic liver disease is generally widespread, and a test for screening fibrotic subjects in a large population is needed. The ability of Wisteria floribunda agglutinin-positive mac-2 binding protein (WFA+-M2BP) to detect significant fibrosis was investigated in health checkup subjects in this research. Of 2021 health checkup subjects enrolled in this prospective cross-sectional study, those with WFA+-M2BP ≥ 1.0 were defined as high risk. Liver fibrosis was evaluated using magnetic resonance elastography (MRE) in subjects with high risk. The primary outcome was the positive predictive value (PPV) of WFA+-M2BP for significant fibrosis (liver stiffness ≥ 2.97 kPa by MRE). This trial was registered with the UMIN clinical trial registry, UMIN000036175. WFA+-M2BP ≥ 1.0 was observed in 5.3% of the 2021 subjects. The PPV for significant fibrosis with the threshold of WFA+-M2BP at ≥1.0, ≥1.1, ≥1.2, ≥1.3, ≥1.4, and ≥1.5 was 29.2%, 36.4%, 43.5%, 42.9%, 62.5%, and 71.4%, respectively. A WFA+-M2BP of 1.2 was selected as the optimal threshold for significant fibrosis among high-risk subjects, and the PPV, negative predictive value, sensitivity, and specificity for significant fibrosis were 43.5%, 84.0%, 71.4%, and 61.8%, respectively. WFA+-M2BP ≥ 1.2 was significantly associated with significant fibrosis, with an odds ratio (OR) of 4.04 (95% confidence interval (CI): 1.1-16, p = 0.04), but not FIB-4 ≥ 2.67 (OR: 2.40, 95%CI: 0.7-8.6, p-value = 0.2). In conclusion, WFA+-M2BP is associated with significant fibrosis and could narrow down potential subjects with liver fibrosis. The strategy of narrowing down fibrosis subjects using WFA+-M2BP may be used to screen for fibrotic subjects in a large population.

BACKGROUND/AIM: Antiviral hepatitis and systemic therapies for hepatocellular carcinoma (HCC) remarkably progressed in the recent 10 years. This study aimed to reveal the actual transition and changes in the prognosis and background liver disease in non-advanced HCC in the past 20 years. METHODS: This retrospectively recruited 566 patients who were diagnosed with non-advanced HCC from February 2002 to February 2022. The prognosis was analyzed by subdividing according to the diagnosis date (period I: February 2002-April 2009 and period â ¡: May 2009-February 2022). RESULTS: Patients in period II (n = 351) were significantly older, with lower albumin-bilirubin (ALBI) scores and alpha-fetoprotein (AFP) and more anti-viral therapy, systemic therapy, and hepatic arterial infusion chemotherapy as compared with those in period I (n = 215). The etiology ratio of the background liver disease revealed decreased hepatitis C virus from 70.6% to 49.0% and increased non-B, non-C from 17.7% to 39.9% from periods I to â ¡. The multivariate analysis revealed older age and higher ALBI score in Barcelona Clinic Liver Cancer (BCLC) 0/A stage, AFP of >20 ng/mL, and higher ALBI score in BCLC B stage as independent prognosis factors. Fine-Gray competing risk model analysis revealed that liver-related deaths significantly decreased in period II as compared to period I, especially for BCLC stage 0/A (HR: 0.656; 95%CI: 0.442-0.972, P = 0.036). CONCLUSION: The characteristics of patients with non-advanced HCC have changed over time. Appropriate background liver management led to better liver-related prognoses in BCLC 0/A.
