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.This study included 105 biopsy-proven NAFLD patients with contemporaneous MRE assessment. The primary outcome was a diagnostic accuracy for significant fibrosis.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).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.

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. The objective response rate and disease control rate in all patients were 18.4% and 63.2%, respectively. Sixteen patients experienced no adverse events (AEs), whereas 4 patients discontinued therapy due to AEs. The median time to progression (TTP) 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 = 0.02). Patients with an AFP response (reduction ≥20% from baseline) at 6 weeks had a significantly longer TTP 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.

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.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.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 ALT21 IU/L was 2.3% and 6.5%, respectively. Patients with ALT21 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).ALT21 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.

Objective Rifaximin is used to treat hepatic encephalopathy. However, whether or not rifaximin and lactulose combination therapy can enhance the treatment outcomes and reduce the hospitalization rate of patients with hepatic encephalopathy that are resistant to lactulose has yet to be determined. The present study investigated the hospitalization rate before and after rifaximin add-on therapy in patients resistant to lactulose. Methods A total of 36 patients who were resistant to lactulose with add-on rifaximin therapy were enrolled. Patients who were hospitalized and/or did not achieve normalization of ammonia levels under lactulose administration were defined as treatment-resistant. The primary outcome was the change in hospitalization rate due to hepatic encephalopathy at 24 weeks before and after rifaximin administration. Results Before rifaximin administration, 15 (41.6%) patients were hospitalized due to hepatic encephalopathy. After rifaximin administration, 8 (22.2%) patients were hospitalized due to hepatic encephalopathy. The hospitalization rates were significantly reduced after rifaximin administration (p=0.02). The median (interquartile range) ammonia levels upon rifaximin administration (baseline) and 8, 12, and 24 weeks after rifaximin administration were 124 (24-310) μg/dL, 78 (15-192) μg/dL, 67 (21-233) μg/dL, and 77 (28-200) μg/dL, respectively. Furthermore, the ammonia levels were significantly reduced by rifaximin add-on therapy (p=0.005, p=0.01, and p=0.01). Conclusion The addition of rifaximin to lactulose treatment in treatment-resistant patients decreases the hospitalization rate among patients with hepatic encephalopathy and may be used as an add-on treatment.

Background and Aim Administration of tenofovir alafenamide (TAF) as prevention or treatment of hepatitis B virus (HBV) reactivation is not well known. The aim of this study is to reveal the efficacy and safety of TAF against HBV reactivation. Methods Entecavir (ETV) and TAF were given to 66 and 11 patients, respectively, as prophylaxis against or treatment of HBV reactivation during chemotherapy or immune suppression therapy from January 2010 to June 2020. The antiviral effects and safety were assessed. Results At week 24, the antiviral effects on patients receiving ETV and TAF were similar in terms of reduction of HBV DNA (−2.83 ± 1.45log IU/mL vs −3.05 ± 2.47log IU/mL; P = 0.857) and achieving undetectable levels of HBV DNA (78.8 vs 90.9%; P = 0.681). There was no significant difference in the decrease in the estimated glomerular filtration rate (eGFR) between the two groups (−0.62 ± 11.2 mL/min/1.73 m2 vs −3.67 ± 13.2 mL/min/1.73 m2; P = 0.291). Conclusion TAF is safe and effective against HBV reactivation., The aim of this study is to reveal the efficacy and safety of tenofovir alafenamide (TAF) as prophylaxis against or treatment of hepatitis B virus (HBV) reactivation. The antiviral effects in terms of HBV DNA reduction on patients receiving entecavir and TAF were similar, and there was no significant difference in renal dysfunction between both groups. TAF is safe and effective against HBV reactivation.

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 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 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 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.

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

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 < 0.01). 44% of patients had no improvement in liver stiffness despite achieving SVR. In patients with advanced fibrosis (lower level of albumin or histological fibrosis stage F4), it was difficult to improve liver stiffness. Except for albumin, there were no blood tests associated with non-improvement 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. This article is protected by copyright. All rights reserved.

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

Background and Aim Loss of hepatitis B surface antigen (HBsAg) is an important goal in the treatment of chronic hepatitis B. We investigated whether switching from long‐term entecavir (ETV) administration to tenofovir (TFV) (tenofovir alafenamide [TAF] or tenofovir disoproxil fumarate [TDF]) could contribute to the reduction of HBsAg levels. Methods The degree of HBsAg reduction by 48 weeks in 30 patients following switching from ETV to TFV was compared with results from 147 patients who continued ETV as a control. Results TFV group switched to TFV after mean 6.79 years of ETV administration. HBV‐DNA levels remained below 1.0 log IU/mL in all cases in both groups during 48 weeks. Median HBsAg reduction at 48 weeks was 0.075 (−0.05 to 0.38) log/IU/mL in the TFV switch group, and 0.070 (−0.28 to 0.50) in the ETV continuation group, which was not statistically significant (p = 0.5). In a subgroup of hepatitis B e antigen negative patients whose HBsAg had not been reduced (HBsAg reduction ≤0 log IU/mL) in the 48 weeks prior to entry into the study, HBsAg reduction was significantly higher in the TFV switch group than in the ETV continuation group (0.15 [0.07–0.135] in TFV, 0.09 [−0.14 to 0.25] log IU/mL in ETV, p = 0.04). Conclusion Although HBsAg reduction is equivalent with ETV continuation and switching to TFV in all patients at 48 weeks, switching from ETV to TFV could provide an alternative therapeutic strategy toward HBsAg elimination in a specific subpopulation of patients., Hepatitis B surface antigen (HBsAg) reduction is equivalent with entecavir (ETV) continuation and switching to TFV in all patients at 48 weeks. However, a significant reduction in HBsAg was observed in a subgroup of Hepatitis B e‐antigen‐negative patients whose HBsAg was not reduced during ETV therapy. In such cases, HBsAg reduction could be expected following a switch to TFV.

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.

BackgroundMagnetic resonance elastography (MRE) has the highest diagnostic accuracy for liver fibrosis; however, the association between MRE-associated liver stiffness and the development of hepatic and extrahepatic complications as well as mortality remains unclear.AimIn this study, we investigated the longitudinal association between MRE-associated liver stiffness and complications and mortality.MethodsThis retrospective study included 2373 consecutive patients with chronic liver disease. All patients received standard of care and the development of complications was assessed every 1-6months.ResultsNewly diagnosed hepatocellular carcinoma (HCC), decompensation, major adverse cardiovascular events (MACE), extrahepatic cancer and death were observed in 99, 117, 73, 77 and 170 patients respectively. In multivariable analysis, the adjusted hazard ratios (aHR) (95% confidence interval [CI]) for HCC, decompensation, MACE, extrahepatic cancer and mortality were 1.28 (1.2-1.4), 1.34 (1.3-1.4), 0.96 (0.9-1.1), 1.00 (0.9-1.1) and 1.17 (1.1-1.2), respectively, with each 1-kPa increase in liver stiffness. Similarly, the aHR (95% CI) for HCC, decompensation, MACE, extrahepatic cancer and mortality were 4.20 (2.2-8.2), 67.5 (9.2-492), 0.83 (0.4-1.7), 0.90 (0.5-1.7) and 2.90 (1.6-5.4), respectively, in patients with cirrhosis (>4.7kPa) compared to those with minimal fibrosis (

Nonalcoholic fatty liver disease (NAFLD) has affected more than one-fourth of the global population, thus emerging as a worldwide health and economic burden.1 The common causes of death in patients with NAFLD include cardiovascular disease (CVD), decompensation, and hepatocellular carcinoma (HCC). However, identifying the risk of these complications in patients with NAFLD remains an unmet need in clinical practice.

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

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.

BACKGROUND AND AIM Tenofovir alafenamide (TAF) is a new prodrug of tenofovir, enabling treatment of patients with hepatitis B virus (HBV) infection at a lower dose than tenofovir disoproxil fumarate (TDF), via more efficient delivery of tenofovir to the hepatocytes. We compared the efficacy and safety of TDF and TAF and investigated switching from TDF to TAF therapy. METHODS Consent for TDF and TAF therapy was obtained from 117 and 67 patients from August 2014 to January 2018. In total, 45 and 14 patients were administered with TDF and TAF, respectively, as naive therapy, and 36 patients were switched from TDF to TAF. The antiviral effects and renal function safety were assessed. RESULTS At week 48, the antiviral effects on patients receiving TDF and TAF as naive therapy were similar in terms of reduction of HBV DNA (-5.6 ± 1.8 logIU/ml vs -5.0 ± 1.7 log IU/ml; P = 0.34) and hepatitis B surface antigen (-0.29 ± 0.64 logIU/ml vs -0.15 ± 0.42 logIU/ml; P = 0.71) levels. A significant decrease in the estimated glomerular filtration rate (eGFR) was seen at 48-week TDF treatment (-5.34 ± 7.69 ml/min/1.73 m2 ; P

e16177 Background: Sarcopenia is associated with clinical outcomes in cirrhosis and hepatocellular carcinoma (HCC). However, the clinical impact of muscle volume during systemic therapy is unknown. We investigated the changes in muscle volume during various systemic therapies for HCC. Methods: The patients with unresectable HCC (u-HCC) treated with a molecular targeted agent as initial systemic therapy were included. The skeletal muscle mass index (SMI) was calculated from the skeletal muscle area at the L3 level of the lumbar vertebrae using computed tomography. Sarcopenia was defined as an L3 SMI value≦42 cm2/m2 for men and 38 cm2/m2 for women. ΔSMI was defined as the difference between baseline and 6-14 weeks after the administration of the agent. Results: A total of 174 patients was analyzed. The 1st-line agent was sorafenib (SOR) (n = 89), lenvatinib (LEN)(n = 58), and atezolizumab plus bevacizumab (ATE+BEV) (n = 27). In three groups, ATE+BEV group had significantly fewer discontinuation due to adverse events. (ATE+BEV 6 cases, LEN 31 cases, SOR 32 cases, p = 0.014). The median PFS was 4.1, 3.0, and 6.1 months in SOR, LEN, and ATE+BEV. The median Δ In patients treated with ATE+BEV, pretreatment sarcopenia was not associated with OS and PFS, while the patients with a SMI decrease (at 6-14W, n = 12) had significantly shorter PFS than the patients without a SMI decrease (n = 15) (p = 0.026). The best radiological response based on RECIST ver1.1 in ATE+BEV was CR (n = 2), PR(n = 6), SD(n = 15), and PD (n = 3). The patients without a SMI decrease tended to have better disease control rate than patients with a SMI decrease (100% vs. 75%, p = 0.08). There were no significant differences in age, etiology, ALBI score, BCLC stage, and pretreatment AFP between the patients with and without a SMI decrease. The significant factor associated with PFS after the administration of ATE+BEV as 1st-line was a decrease of SMI (HR9.44, 95% CI 1.04-85.6, p = 0.046). In patients treated with SOR and LEN, pretreatment sarcopenia and SMI decrease were not significantly associated with OS and PFS. Conclusions: The decrease of muscle volume at 6-14W was significantly associated with PFS in patients treated with ATE+BEV, while pretreatment sarcopenia was not a significant factor. Monitoring muscle volume during immunotherapy would be useful in clinical practice.

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

We appreciate the interest in our article and comments by Wang et al. Hepatocellular carcinoma (HCC) development risk changes over time during nucleotide/nucleoside analog (NA) therapy. Therefore, HCC risk prediction not only at NA administration but also after NA administration is important in clinical practice, and the aim of the study was to evaluate the diagnostic accuracy of HCC risk scores (PAGE-B, modified PAGE-B [mPAGE-B], and REACH-B) at three points (NA administration, and 1 and 2 years after NA administration)1 . HCC risk scores were calculated at three points (NA administration and 1 and 2 years after NA administration), and subsequent HCC development was evaluated.

BackgroundWe aimed to investigate the efficacy and safety of ramucirumab therapy in Japanese patients with unresectable hepatocellular carcinoma (u-HCC) in real-world practice.MethodsA total of 16 patients with u-HCC were treated with ramucirumab of ≥2 cycles between July 2019 and April 2020. Modified response evaluation criteria in solid tumors (RECIST) and RECIST version 1.1 were used to evaluate radiological responses.ResultsThe patients received ramucirumab as second-line (n = 4), third-line (n = 2), and fourth-line (n = 10). Median observation period was 3.7 months and 3 patients treated as fourth-line died from HCC progression. According to modified RECIST, the objective response rate (ORR) and disease control rate (DCR) were 27.2% and 81.8%, respectively. ORR and DCR by RECIST version 1.1 were 9.1 % and 72.7%, respectively. PFS at 3 months was 68.2%. Drug discontinuation caused by adverse events (AEs) was reported in 7 patients treated as fourth-line and 1 patient as third-line. Pretreatment creatinine (Cr) and estimated glomerular filtration rate (eGFR) were significantly higher in patients with discontinuation owing to AEs (P = 0.01 and P = 0.02). Urine protein-to-creatine ratio after 4 weeks was significantly higher in patients with impaired renal function than patients with preserved renal function (0.93 vs. 0.14; P = 0.017).ConclusionRamucirumab therapy was found to have similar radiological responses between u-HCC patients with single and multiple experiences of TKI therapies. The pretreatment factors would be associated with the incidence of AEs during the therapy.

Nucleos(t)ide analogs (NA) suppress hepatitis B virus (HBV) replication and reduce the risk of hepatocellular carcinoma (HCC). However, NA cannot suppress carcinogenesis completely in patients with chronic hepatitis B. The aims of this study were to identify risk factors for HCC and develop a refined carcinogenesis prediction model. Patients receiving NA therapy (n = 1,183) were recruited retrospectively from the 16 hospitals. All patients had been receiving NA continuously for more than 1 year until the end of the follow-up. During a median follow-up of 4.9 (1.0–12.9) years, 52 (4.4%) patients developed HCC. A multivariate analysis revealed that male gender, older age, lower platelet counts at the baseline, and detectable HBV DNA during NA therapy were independent predictive factors of HCC development. The PAGE-B score was calculated by using these factors. 240 (20.3%), 661 (55.9%), and 282 (23.8%) patients were classified into low-, intermediate-, and high-risk groups, respectively. In the intermediate- and high-risk group, detectable HBV DNA was significantly associated with a higher risk of HCC development compared with continuously undetectable HBV DNA, respectively (HR 3.338; 95% CI 1.045–10.66/HR 3.191; 95% CI 1.543–6.597). PAGE-B–DNA, which is the combined PAGE-B and HBV DNA status, was valuable for a more refined stratification of PAGE-B.

Background and Aim Lenvatinib (LEN) has an antitumor effect with an early reduction in contrast enhancement for unresectable hepatocellular carcinoma (HCC). The aim of this study was to reveal the most useful radiological response evaluation for overall survival (OS) in patients treated with LEN. Methods Patients receiving LEN therapy (n = 80) were retrospectively recruited from April 2018 to January 2020. Enhanced computed tomography scans were performed at baseline and every 4–8 weeks. OS and radiological response were evaluated using response evaluation criteria in solid tumors (RECIST 1.1), modified RECIST (mRECIST), and Choi criteria. To be eligible for study, a minimal cumulative duration of LEN was 4 weeks. A total of 62 patients were included in the analysis. Results The median OS was 469 days. The RECIST 1.1, mRECIST, and Choi criteria identified 14 (22.5%), 30 (48.3%), and 33 (53.2%) patients with an objective response, respectively. In the univariate analysis, Child–Pugh class B, major vascular invasion, and high alpha‐fetoprotein (>200) were statistically significant poor prognostic factors. Radiological response was a significantly better prognostic factor in each criterion (RECIST, mRECIST, and Choi). In the multivariate analysis, radiological response evaluated by RECIST (hazard ratio, 0.259; 95% confidence interval, 0.0723–0.928; P = 0.038) was an independent factor. Furthermore, only RECIST significantly stratified prognosis (P = 0.041) when limited to the first evaluation. Conclusion RECIST 1.1 was useful even as early therapeutic evaluation for HCC patients treated with LEN. Understanding the characteristics of radiological response over time may contribute to improving the prognosis of patients with HCC., The RECIST 1.1 was a useful, even early, therapeutic evaluation for hepatocellular carcinoma patients treated with lenvatinib. Maintaining relative dose intensity of lenvatinib is crucial after the first evaluation, especially with the mRECIST and Choi criteria, which evaluate staining, in Barcelona Clinic Liver Cancer stage B patients.

Identification of high-risk patients for hepatocellular carcinoma (HCC) after sustained virological responses (SVR) is necessary to define candidates for long-term surveillance. In this study, we examined whether serum markers after 1 year of SVR could predict subsequent HCC development. Total 734 chronic hepatitis C patients without a history of HCC who achieved SVR with direct-acting antivirals were included. The regular surveillance for HCC started from 24 weeks after the end of treatment (SVR24). Factors at SVR24 and 1 year after SVR24 were analyzed for predicting HCC development. During the mean observation period of 19.7 &plusmn, 10 months, 24 patients developed HCC. At SVR24, Wisteria floribunda agglutinin-positive mac-2 binding protein (WFA&plusmn, M2BP) &ge, 1.85 and &alpha, fetoprotein (AFP) &ge, 6.0 ng/mL were independent factors of HCC development. However, at 1 year after SVR24, WFA&plusmn, M2BP &ge, 1.85 was associated with subsequent HCC development (hazard ratio: 23.5, 95% confidence interval: 2.68&ndash, 205) but not AFP. Among patients with WFA&plusmn, 1.85 at SVR24, 42% had WFA&plusmn, M2BP &lt, 1.85 at 1 year after SVR24 (WFA&plusmn, M2BP declined group). Subsequent HCC development was significantly lower in the declined group than in the non-declined group (1 year HCC rate: 0% vs. 9.4%, p = 0.04). In conclusion, WFA&plusmn, M2BP but not AFP could identify high and no-risk cases of HCC at 1 year after SVR. Therefore, it was useful as a real-time monitoring tool to identify the candidates for continuous surveillance for HCC.

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.A total of 610 patients with advanced fibrosis were enrolled in the study. ABP criteria are defined as follows: albumin4.0 g/dL, bilirubin22 μmol/L, and platelets114 000/μL.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 bilirubin22 μmol/L (HR 2.00, 95% CI 1.2-3.4), albumin4.0 g/dL (HR 2.56, 95% CI 1.7-3.8), and platelets114 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.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.

To evaluate the effects of l-carnitine on impaired brain function in patients with liver cirrhosis. We conducted a retrospective cohort study that included sequential 80 liver cirrhosis patients with impaired brain function evaluated using near-infrared spectroscopy (NIRS). Among them, l-carnitine was administered to 48 patients. The NIRS data and blood ammonia level at baseline and after 8 weeks of treatment were compared between patients administered with l-carnitine (l-carnitine group) and those who were not (control group). The NIRS data at baseline were similar between the l-carnitine and control groups (0.04 ± 0.04 vs. 0.04 ± 0.05 mMmm, p = n.s), whereas those in the l-carnitine group (n = 48) were significantly better than that of the control group at 8 weeks of treatment (n = 32) (0.103 ± 0.081 vs. 0.040 ± 0.048 mMmm, p l-carnitine group, 35.4% (17/48) of patients had hyperammonemia. The NIRS data of the l-carnitine group at 8 weeks of treatment were significantly improved than that of the control group, irrespective of baseline ammonia levels (0.11 ± 0.09 vs. 0.04 ± 0.05 mMmm, p = 0.005, and 0.10 ± 0.06 vs. 0.02 ± 0.03 mMmm, p = 0.003, for normal baseline ammonia and elevated ammonia levels, respectively). In the multivariate analysis, l-carnitine administration (odds ratio [OR] 3.51, 95% confidence interval [CI] 1.23–9.99, p = 0.019) and baseline NIRS data of ≤ 0.07 mMmm (OR 5.21, 95% CI 1.69–16.0, p = 0.0041) were found as independent significant factors. l-carnitine improves impaired brain function in patients with liver cirrhosis.

447 Background: In systemic therapy for unresectable HCC, atezolizumab plus bevacizumab is recommended as first-line, and there are no established strategies after the immunotherapy. Lenvatinib (LEN) showed a high radiological response rate both in clinical trials and real-world practice, while it was reported that age and ALBI grade 2 were associated with the discontinuation of LEN. The aim of this study is to investigate the best candidates for LEN therapy by using clinical variables. Methods: A total of 104 patients who received LEN at our institution between Apr 2018 and Feb 2021 was enrolled. The risk factors associated with overall survival (OS) and progression-free survival (PFS) were analyzed by a Cox proportional hazard model. Results: The median observation period was 12.8 months, and the median duration of LEN was 4.5 months. The median age was 74 years, and 90 patients were Child-Pugh A. BCLC stage B patients were 43%, and median AFP was 172 ng/mL. The median OS and PFS were 17.9 and 6.2 months. In this study, 72 patients received LEN as the first line. In a multivariate analysis of first-line patients, ECOG PS≥1, modified ALBI 2b or 3, AFP≥400 ng/mL, the existence of major vascular invasion (MVI), and neutrophil to lymphocyte ratio (NLR)≥2.8 were significant risk factors associated with OS and PFS. The median OS in patients with 0-1 risk factor (n = 33) was significantly longer than the patients with 2-5 risk factors (n = 39) (22.3 vs. 16.7 months, p

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

Background: We aimed to explore the relative dose intensity (RDI) and post-regorafenib treatments in regorafenib therapy. Methods: The medical records of 38 patients treated with regorafenib between July 2017 and June 2019 at our institution were collected. The RDI of regorafenib for the first month (1M-RDI) was calculated. Results: The overall survival (OS) and progression-free survival (PFS) were 12.4 and 3.7 months. The objective response rate and disease control rate were 13.2% and 71.1%. The median total dose of regorafenib in the first month was 2080 mg (240&ndash, 3360 mg), and the median 1M-RDI was 61.9% (7.1%&ndash, 100%). Patients with 1M-RDI &ge, 50% showed significantly longer OS and PFS than patients with 1M-RDI &lt, 50% (HR 0.19, 95% CI 0.08&ndash, 0.48, p = 0.0004 and HR 0.2, 95% CI 0.08&ndash, 0.52, p = 0.0008). A 1M-RDI &ge, 50% (HR 0.18, 95% CI 0.06&ndash, 0.55, p = 0.002) and hand&ndash, foot skin reaction (HR 0.03, 95% CI 0.008&ndash, 0.16, p &lt, 0.0001) were independently associated with OS. Post-regorafenib therapies were performed in 19 (86.4%) of 22 patients who had stopped regorafenib due to disease progression. Conclusion: A 1M-RDI &ge, 50% is clinically significant. Post-regorafenib therapies are commonly performed in real-world practice.

The assessment of liver fibrosis is essential because it correlates with mortality risk in nonalcoholic fatty liver disease (NAFLD). This study aims to examine whether serum fibrosis markers could identify candidate patients likely to have advanced fibrosis. We enrolled 352 patients with NAFLD and performed liver biopsies in 97 patients. The area under the receiver operating characteristic curve (AUROC) of liver stiffness by magnetic resonance elastography for histological advanced fibrosis was 0.910, and the optimal cutoff value was 4.07 kPa. To predict severe liver stiffness (≥4.07 kPa), the AUROC for Wisteria floribunda agglutinin-positive mac-2 binding protein (WFA+-M2BP) and FIB-4 were 0.897 (cutoff value, 1.08) and 0.880 (cutoff value, 2.53), respectively. After stratification of patients into four age groups as quartile, the optimal cutoff values of WFA+-M2BP for predicting severe liver stiffness were similar in each group (1.09, 1.08, 1.10, and 1.12). On the other hand, those of FIB-4 increased in parallel with age (1.47, 2.19, 2.99, and 3.88). In conclusion, WFA+-M2BP was precise for estimating severe liver stiffness in NAFLD with single cutoff value independent of age. Hence, identifying high-risk cases using WFA+-M2BP from a large number of NAFLD patients is clinically significant.

Prediction of hepatocellular carcinoma (HCC) development after sustained virological response (SVR) is clinically important, and the usefulness of noninvasive markers for prediction HCC have been reported. The aim of this study was to compare the prediction accuracy for HCC development by noninvasive markers. A total of 346 patients with chronic hepatitis C without history of HCC who achieved SVR through direct-acting antivirals were included. Magnetic resonance elastography (MRE) and serum fibrosis markers were measured 12 weeks after the end of treatment, and the subsequent HCC development was examined. The mean observation period was 26.4 ± 7.9 months, and 24 patients developed HCC. Area under the receiver operating characteristic curve of liver stiffness by MRE, Wisteria floribunda agglutinin-positive mac-2 binding protein and FIB-4 for predicting HCC within 3 years was 0.743, 0.697 and 0.647, respectively. The 1/2/3-year rates of HCC development in patients with liver stiffness ≥3.75 KPa were 6.6%, 11.9% and 14.5%, whereas they were 1.4%, 2.5% and 2.5% in patients with liver stiffness

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 &ge, 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 &ge, 2.97 kPa by MRE). This trial was registered with the UMIN clinical trial registry, UMIN000036175. WFA+-M2BP &ge, 1.0 was observed in 5.3% of the 2021 subjects. The PPV for significant fibrosis with the threshold of WFA+-M2BP at &ge, 1.0, &ge, 1.1, &ge, 1.2, &ge, 1.3, &ge, 1.4, and &ge, 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 &ge, 1.2 was significantly associated with significant fibrosis, with an odds ratio (OR) of 4.04 (95% confidence interval (CI): 1.1&ndash, 16, p = 0.04), but not FIB-4 &ge, 2.67 (OR: 2.40, 95%CI: 0.7&ndash, 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.
