RESUMO
Early-stage hepatocellular carcinoma (HCC) is still difficult to cure for its high recurrence rate. This study aimed to examine whether glycemic burden management could be one way to improve outcomes of early-stage HCC. A total of 137 very early or early-stage HCC patients who underwent resection or ablation at Samsung Medical Center and had glycemic burden assessment were analyzed. Glycemic burden was assessed using hemoglobin A1c (HbA1c) level. Outcomes were recurrence and overall survival. Risks of recurrence and overall survival were compared according to glycemic burden using a cut-off point of 6.5% or two cut-off points of 6.0% and 7.5%. Overall, 51 (37.2%) patients experienced HCC recurrence. The adjusted hazard ratio (aHR) for recurrence comparing patients with HbA1c > 6.5% to those with HbA1c ≤ 6.5% was 2.66 (95% CI: 1.26-5.78). The risk of recurrence increased in a dose-dependent manner by glycemic burden; aHR for 6.0 < HbA1c ≤ 7.5%: 2.00 (95% CI: 0.78-5.55); aHR for HbA1c > 7.5%: 6.05 (95% CI: 2.31-17.5). Mortality was observed in 16 (11.7%) patients. The risk of mortality was higher for HbA1c > 6.5% than for HbA1c ≤ 6.5% (aHR: 2.33; 95% CI: 1.10-5.08). There was also a dose-response relationship between overall survival and glycemic burden. Glycemic burden assessed using HbA1c level was significantly associated with outcomes of early-stage HCC patients. Good glycemic control could be a therapeutic goal to improve clinical outcomes in these populations.
RESUMO
International liver societies recommend hepatocellular carcinoma (HCC) surveillance for those at high-risk of developing HCC. While previous studies have shown the benefits of surveillance for middle-aged patients, but its necessity for elderly patients is unclear. This study aimed to assess the benefits of HCC surveillance in the elderly by comparing diagnosis mode of HCC. Consecutive, elderly patients aged 75 years or older who were newly diagnosed with HCC were screened at our institution between January 2009 and December 2021. Patients were grouped into those who were diagnosed with HCC during surveillance (n = 235, surveillance group) and those who were diagnosed with HCC due to symptoms (n = 184, symptomatic group). The study outcome was overall survival. It was compared in the overall cohort and a propensity score (PS)-matched cohort. Early-stage diagnosis was more frequent in the surveillance group than in the symptomatic group (mUICC stage I/II: 72.3% vs. 39.1%, p < 0.001). The overall survival rate was better in the surveillance group than in the symptomatic group (median 4.4 vs. 2.1 years, log-rank p < 0.001). In multivariable-adjusted models, the hazard ratio (HR) of mortality of the surveillance group compared to the symptomatic group was 0.64 (95% confidence interval (CI): 0.47-0.87). However, further adjustment for the tumor stage markedly attenuated this association, which was no longer statistically significant (adjusted HR = 0.75; 95% CI: 0.54-1.02). In the PS-matched cohort analysis, outcomes were similar when the PS matching variables included the tumor stage. In contrast, when PS matching variables did not include the tumor stage, outcomes were better for the surveillance group. The surveillance group of elderly patients showed better survival than the symptomatic group, which was largely explained by earlier tumor stage at diagnosis. This suggests that the overall outcome of elderly HCC patients could be improved by increasing surveillance-detected cases compared to symptom-driven cases.

Background/Aims: Atezolizumab and bevacizumab have shown promising results for the treatment of advanced hepatocellular carcinoma (HCC) in clinical trials. In this study, the real-world efficacy and safety of atezolizumab and bevacizumab in treating advanced HCC were evaluated. Methods: In this retrospective study of patients at a Korean tertiary cancer center, 111 patients with Barcelona Clinic Liver Cancer stage B or C HCC received atezolizumab and bevacizumab as first-line therapy from May 2022 to June 2023. We assessed the progression-free survival (PFS), overall response rate (ORR), disease control rate (DCR), and adverse events. Results: Patients with Barcelona Clinic Liver Cancer stage C HCC and Child-Pugh class A liver function were included in the study. The median PFS was 6.5 months, with an ORR of 27% and a DCR of 63%. Several factors, including the albumin-bilirubin grade, age, C-reactive protein and α-fetoprotein in immunotherapy score, macrovascular invasion, lung metastases, and combined radiotherapy, were found to significantly influence PFS (p<0.05). Patients with peritoneal seeding showed an higher ORR. The safety profile was consistent with that observed in clinical trials. Conclusions: Atezolizumab and bevacizumab demonstrated real-world efficacy in the treatment of advanced HCC, with ORRs and DCRs aligning with those observed in clinical trials. Variations in PFS and ORR based on specific risk factors highlight the potential of atezolizumab and bevacizumab in precision medicine for advanced HCC.

Background/Aims: Systemic therapy is the current standard treatment for hepatocellular carcinoma (HCC) with extrahepatic metastases (EHM). However, some patients with HCC and EHM undergo transarterial chemoembolization (TACE) to manage intrahepatic tumors. Herein, we aimed to explore the appropriateness of TACE in patients with HCC and EHM in an era of advanced systemic therapy. Methods: This study analyzed 248 consecutive patients with HCC and EHM (median age 58.5 years, 83.5% male, and 88.7% Child-Pugh A) who received TACE or systemic therapy (83 sorafenib, 49 lenvatinib, 28 immunotherapy-based) between January 2018 and January 2021. Results: Among the patients, 196 deaths were recorded during a median follow-up of 8.9 months. Patients who received systemic therapy had a higher albumin-bilirubin grade, elevated tumor markers, an increased number of intrahepatic tumors, larger-sized tumors, and more frequent portal vein invasion than those who underwent TACE. TACE was associated with longer median overall survival (OS) than sorafenib (15.1 vs. 4.7 months; 95% confidence interval [CI]: 11.1-22.2 vs. 3.7-7.3; hazard ratio [HR] 1.97, P<0.001). After adjustment for potential confounders, TACE was associated with statistically similar survival outcomes to those of lenvatinib (median OS: 8.0 months; 95% CI: 6.5-11.0; HR 1.21, P=0.411) and immunotherapies (median OS: 14.3 months; 95% CI: 9.5-27.0; HR 1.01, P=0.973), demonstrating survival benefits equivalent to these treatments. Conclusion: In patients with HCC and EHM, TACE can provide a survival benefit comparable to that of newer systemic therapies. Accordingly, TACE remains a valuable option in this era of new systemic therapies.
RESUMO
Introduction: Hepatocellular carcinoma (HCC) is the sixth most commonly diagnosed cancer and the third leading cause of cancer death worldwide. While there has been rapid evolution in the treatment paradigm of HCC across the past decade, the extent to which these newly approved therapies are utilized in clinical practice in the real world is, however, unknown. The INSIGHT study was an investigator-initiated, multi-site longitudinal cohort study conducted to reflect real-world epidemiology and clinical practice in Asia-Pacific in the immediate 7-year period after the conclusion of the BRIDGE study. Methods: Data were collected both retrospectively (planned 30% of the total cohort size) and prospectively (planned 70%) from January 2013 to December 2019 from eligible patients newly diagnosed with HCC from 33 participating sites across 9 Asia-Pacific countries. Results: A total of 2,533 newly diagnosed HCC patients (1,052 in retrospective cohort and 1,481 in prospective cohort) were enrolled. The most common risk factor was hepatitis B in all countries except Japan, Australia, and New Zealand, where the prevalence of hepatitis C and diabetes were more common. The top three comorbidities reported in the INSIGHT study include cirrhosis, hypertension, and diabetes. We observe high heterogeneity in the first-line treatment recorded across countries and across disease stages, which significantly affects survival outcomes. Stratification by factors such as etiologies, tumor characteristics, the presence of extrahepatic metastases or macrovascular invasion, and the use of subsequent lines of treatment were performed. Conclusion: The INSIGHT study describes a wide spectrum of clinical management practices in HCC, where patient demographics, differential costs, and patient access to therapies may lead to wide geographical variations through the patient's treatment cycle, from diagnosis to clinical outcome. The high heterogeneity in patient outcomes demonstrates the need for more robust and clinical management strategies to be designed and adopted to bring about better patient outcomes.
RESUMO
BACKGROUND/AIMS: Improved knowledge of local epidemiology and predicting risk factors of multidrug-resistant (MDR) bacteria are required to optimize the management of infections. This study examined local epidemiology and antibiotic resistance patterns of liver cirrhosis (LC) patients and evaluated the predictors of MDR bacteremia in Korea. METHODS: This was a retrospective study including 140 LC patients diagnosed with bacteremia between January 2017 and December 2022. Local epidemiology and antibiotic resistance patterns and the determinants of MDR bacteremia were analyzed using logistic regression analysis. RESULTS: The most frequently isolated bacteria, from the bloodstream, were Escherichia coli (n = 45, 31.7%) and Klebsiella spp. (n = 35, 24.6%). Thirty-four isolates (23.9%) were MDR, and extended-spectrum beta-lactamase E. coli (52.9%) and methicillin-resistant Staphylococcus aureus (17.6%) were the most commonly isolated MDR bacteria. When Enterococcus spp. were cultured, the majority were MDR (MDR 83.3% vs. 16.7%, p = 0.003), particularly vancomycin-susceptible Enterococcus faecium. Antibiotics administration within 30 days and/or nosocomial infection was a significant predictor of MDR bacteremia (OR: 3.40, 95% CI: 1.24-9.27, p = 0.02). MDR bacteremia was not predicted by sepsis predictors, such as positive systemic inflammatory response syndrome (SIRS) or quick Sequential Organ Failure Assessment (qSOFA). CONCLUSION: More than 70% of strains that can be treated with a third-generation cephalosporin have been cultured. In cirrhotic patients, antibiotic administration within 30 days and/or nosocomial infection are predictors of MDR bacteremia; therefore, empirical administration of broad-spectrum antibiotics should be considered when these risk factors are present.

Introduction: We aimed to investigate whether concurrent use of intrahepatic external beam radiotherapy (EBRT) is a viable option for patients with advanced hepatocellular carcinoma (HCC) undergoing tyrosine kinase inhibitor (TKI) therapy. Methods: A total of 453 patients with Barcelona Clinic Liver Cancer stage C (BCLC C) HCC, who started first-line treatment with TKI with intrahepatic EBRT (TKI + RT, n = 97) or TKI without intrahepatic EBRT (TKI, n = 356) were analyzed. The overall survival (OS) and progression-free survival (PFS) were compared in the overall cohort, patients who received at least 8 weeks of TKI treatment and a propensity score-matched cohort. Results: OS and PFS were better in those treated with TKI + RT than TKI (8.6 vs. 4.4 months and 4.5 vs. 2.3 months, respectively, with p < 0.001). Of note, the TKI + RT group demonstrated significantly longer time to intrahepatic tumor progression. In subgroup analysis, TKI + RT led to better OS than TKI in all subgroups and PFS was significantly improved in patients without extrahepatic metastasis and those with portal vein invasion. There was no significant difference in treatment discontinuation due to adverse events between the TKI + RT and TKI groups (32.0% vs. 37.9%, p = 0.34). Furthermore, patients treated with TKI + RT showed better liver function preservation over time compared to TKI without intrahepatic EBRT. Comparable treatment outcomes were observed between patients who received at least 8 weeks of TKI treatment and the propensity score-matched cohort. Conclusion: Concurrent intrahepatic EBRT targeting the liver and/or macrovascular invasion can be a viable option to improve outcomes of BCLC stage C patients receiving TKI therapy with an aim to control intrahepatic progression and preserving the liver function.
RESUMO
Background & Aims: The metabolic dysfunction-associated fatty liver disease (MAFLD) is a new inclusive term proposed to replace non-alcoholic fatty liver disease (NAFLD). We analysed whether hepatocellular carcinoma (HCC) risk differs by MAFLD or NAFLD status in a large sample of asymptomatic adults. Methods: A cohort comprising 73,691 adults were followed up for the development of HCC. NAFLD was diagnosed among participants without other liver diseases (n = 65,992). Results: Participants with MAFLD showed higher incidence of HCC than those without MAFLD (0.37 and 0.24 per 1,000 person-years, respectively; p = 0.006). However, MAFLD was not an independent factor associated with HCC in multivariable adjusted analysis (hazard ratio [HR] 1.21; 95% CI 0.92-1.60). When stratified according to presence of other liver diseases, MAFLD was not associated with HCC in participants with other liver diseases. In participants without other liver diseases, both MAFLD (adjusted HR 1.84; 95% CI 1.09-3.11) and NAFLD (adjusted HR 1.71; 95% CI 1.01-2.90) were independent factors associated with HCC. When stratified according to NAFLD and MAFLD status, there was no HCC development among participants with NAFLD only during 8,936 person-years of follow-up, but this NAFLD-only group comprised 3.4%, and the majority of participants with hepatic steatosis fulfilled both NAFLD and MAFLD criteria. Conclusions: In patients with other chronic liver diseases, the presence of MAFLD is not independently associated with an increased risk of HCC. For those without other chronic liver diseases, MAFLD largely overlaps with NAFLD and is associated with an increased risk of HCC. Impact and Implications: This study investigated the usefulness of newly proposed nomenclature, metabolic dysfunction-associated fatty liver disease (MAFLD), over non-alcoholic fatty liver disease (NAFLD), in terms of predicting hepatocellular carcinoma. In patients with other chronic liver diseases, the presence of MAFLD is not independently associated with an increased risk of HCC. However, for those without chronic liver disease, MAFLD largely overlaps with NAFLD and is associated with an increased risk of HCC.
RESUMO
BACKGROUND AND AIMS: Baveno VII consensus introduced the non-invasive criteria of clinically significant portal hypertension (CSPH) using liver stiffness measurement (LSM). We evaluated the usefulness of the Baveno VII criteria to predict the risk of decompensation in patients with compensated advanced chronic liver disease (cACLD). METHODS: We conducted a retrospective cohort study of 1966 patients with cACLD. Patients were categorized into four groups (CSPH excluded (n = 619), grey zone (low risk of CSPH (n = 699), high risk of CSPH (n = 207)), and CSPH included (n = 441)) according to Baveno VII consensus. The risk of events was estimated using a Fine and Gray competing risk regression analysis, with liver transplantation and death as competing events. We calculated standardized hazard ratios (sHR) to assess the relative risk of decompensation. RESULTS: Among 1966 patients, 178 developed decompensations over a median follow-up of 3.06 (IQR: 1.03-6.00) years. Patients with CSPH had the highest decompensation risk, followed by the grey zone high-risk group, grey zone low-risk group, and those without CSPH with 3-year cumulative risks of 22%, 12%, 3.3%, and 1.4% respectively (p < .001). Compared to CSPH excluded group, CSPH included group (sHR: 8.00, 95% CI: 4.00-16.0), grey zone high-risk group (sHR: 6.57, 95% CI: 3.16-13.6), grey zone low-risk group (sHR: 2.15, 95% CI: 1.04-4.41) had significantly higher risk of decompensation (Gray's test p < .01). CONCLUSION: Non-invasive diagnosis of CSPH according to the Baveno VII criteria can stratify the risk of decompensation.

Normalization of serum alanine aminotransferase (ALT) levels is one of the goals of hepatitis B treatment. However, ALT levels in cirrhosis patients might be normal or mildly elevated regardless of ongoing inflammation. Therefore, we examined whether on-treatment ALT and other potential on-treatment indicators could be clinical surrogates of antiviral therapy in HBV-related cirrhosis. A total of 911 patients with HBV-related liver cirrhosis who started treatment with entecavir or tenofovir were analyzed. At 1 year of antiviral therapy, we evaluated 'ALT normalization', 'undetectable serum HBV DNA', 'fibrosis-4 (FIB-4) index improvement', and 'serum HBeAg loss' as potential biomarkers for HCC development. During 6.6 (3.8-10.2) years of follow-up, 222 patients (24.3%) newly developed HCC. Undetectable HBV DNA levels at 1 year were observed in 667 patients (73.2%), and the HCC incidence was significantly lower in this population (adjusted hazard ratio (HR) 0.66, 95% CI 0.50-0.87). Improvement of the FIB-4 index (< 3.25) was associated with a lower risk of HCC in 478 patients with an elevated FIB-4 index (adjusted HR 0.59, 95% CI 0.55-0.82). However, there was no significant difference in HCC risk between those with and without normalization of ALT levels (p = 0.39) among those with elevated ALT levels or between those with and without HBeAg seroconversion (p = 0.55) among HBeAg-positive patients. Therefore, on-treatment FIB-4 levels at 1 year are clinically useful surrogates of antiviral therapy for HBV-related cirrhosis patients.

Background/Aims: The ursodeoxycholic acid (UDCA) response score (URS) was developed to identify poor responders to UDCA before treatment, in order to offer timely and proactive intervention. However, validation of the URS in Asian population is warranted. Methods: A total of 173 Asian patients diagnosed with primary biliary cholangitis (PBC) between 2007 and 2016 at seven academic institutions in Korea who started UDCA treatment were analyzed to validate the performance of URS. UDCA response was defined as an alkaline phosphatase level less than 1.67 times the upper limit of normal after 1-year of UDCA treatment. In addition, prognostic performance of URS for liver-related events, defined as newly developed hepatic decompensation or hepatocellular carcinoma was evaluated. Results: After 1 year of UDCA treatment, 133 patients (76.9%) achieved UDCA response. UDCA response rate was 98.7% for those with URS ≥1.41 (n=76) and 58.8% for those with URS <1.41 (n=97). The area under the receiver operating characteristic curve of URS in predicting UDCA response was 0.84 (95% confidence interval, 0.78 to 0.88). During a median follow-up of 6.5 years, liver-related events developed in 18 patients (10.4%). Among 117 patients with PBC stage I-III by histological evaluation, the 5-year liver-related event-free survival rate differed according to the URS; 100% for URS ≥1.41 and 86.5% for URS <1.41 (p=0.005). Conclusions: URS demonstrated good performance in predicting a UDCA treatment response in Asian PBC patients. In addition, the risk of liver-related events differed according to the URS for the PBC stage. Thus, URS can be used to predict the response and clinical outcome in patients with PBC.

Background/Aims: This study aimed to investigate whether pretransplant frailty can predict postoperative morbidity and mortality after liver transplantation (LT) in patients with cirrhosis. Methods: We retrospectively reviewed 242 patients who underwent LT between 2018 and 2020 at a tertiary hospital in Korea. Results: Among them, 189 patients (78.1%) received LT from a living donor. Physical frailty at baseline was assessed by the Short Physical Performance Battery (SPPB), by which patients were categorized into two groups: frail (SPPB <10) and non-frail (SPPB ≥10). Among the whole cohort (age, 55.0±9.2 years; male, 165 [68.2%]), 182 patients were classified as non-frail and 60 patients were classified as frail. Posttransplant survival was shorter in the frail group than the non-frail group (9.3 months vs 11.6 months). Postoperative intensive care unit stay was longer in the frail group than in the non-frail group (median, 6 days vs 4 days), and the 30-day complication rate was higher in the frail group than in the non-frail group (78.3% vs 59.3%). Frailty was an independent risk factor for posttransplant mortality (adjusted hazard ratio, 2.38; 95% confidence interval, 1.02 to 5.57). In subgroup analysis, frail patients showed lower posttransplant survival regardless of history of hepatocellular carcinoma and donor type. Conclusions: Assessment of pretransplant frailty, as measured by SPPB, provides important prognostic information for clinical outcomes in cirrhotic patients undergoing LT.

OBJECTIVE: This study aimed to determine whether hepatocellular carcinoma (HCC) risk and time to HCC development differ according to hepatobiliary magnetic resonance imaging (MRI) findings among people at risk for developing HCC. MATERIALS AND METHODS: A total of 199 patients aged 40 years or older with liver cirrhosis or chronic liver disease who underwent gadoxetic acid-enhanced hepatobiliary MRI between 2011 and 2015 were analyzed. An independent radiologist retrospectively reviewed MRI findings, blinded to clinical information, and categorized them into low-risk features, high-risk features and high-risk nodules. High-risk features were defined as liver cirrhosis diagnosed by imaging. High-risk nodules were defined as LR-3 or LR-4 nodules based on LI-RADS version 2018. The primary outcome was development of HCC within 5-year of MRI evaluation. RESULTS: HCC was diagnosed in 28 patients (14.1%). HCC development was null for those with low-risk features (n = 84). The cumulative incidence rates of HCC were 0%, 2.3%, 13.4% and 22.1% at 1-, 2-, 3- and 5-year for those with high-risk features (n= 64), and were 19.1%, 31.8%, 37.3% and 46.7% at 1-, 2-, 3- and 5-year for those with high-risk nodules (n= 51). Among 28 patients developed HCC, the median time from baseline MRI to HCC diagnosis was 33.1 months (interquartile range: 25.9-46.7 months) for high-risk feature group, and 17.3 months (interquartile range: 6.2-26.5 months) for high-risk nodule group. CONCLUSIONS: HCC risk and time to HCC development differ according to baseline hepatobiliary MRI findings, indicating that hepatobiliary MRI findings can be used as biomarkers to differentiate HCC risk.

Background: This study aimed to compare the clinical outcomes of patients with hepatocellular carcinoma (HCC) and macroscopic tumor thrombosis who were treated with lenvatinib with or without combined liver-directed radiotherapy (LRT). Methods: From the institutional registry, we enrolled 82 patients diagnosed with HCC involving macroscopic tumor thrombosis and treated with lenvatinib monotherapy (non-LRT group, n = 54, 65.9%) or lenvatinib in combination with LRT (LRT group, n = 28, 34.1%). Patients were classified into the LRT group if LRT was performed within 8 weeks of lenvatinib initiation. Results: During the median follow-up period of 5.4 (range 1.4 to 17.5) months, there was no significant difference between the two groups in terms of overall adverse events. Although there was no statistical difference between the two groups in terms of overall response rate (32.1% vs. 20.4%, p = 0.15), a significantly higher treatment response was observed in the LRT group in terms of intrahepatic tumor response (67.9% vs. 20.4%, p < 0.001). In the LRT group, there was a slight difference in overall survival compared to the non-LRT group (64.1% in the LRT group vs. 37.7% in the non-LRT group at 12 months, hazard ratio [HR], 0.54; 95% confidence interval [CI] 0.28-1.03; p = .06), although it did not reach a statistically significant level. However, progression-free survival (PFS, 67.2% in the LRT group vs. 35.0% in the non-LRT group at 6 months, HR 0.47; 95% CI 0.27-0.82; p = 0.008) and intrahepatic progression-free survival (IHPFS, 74.3% in the LRT group vs. 43.3% in the non-LRT group at 6 months, HR 0.45; 95% CI 0.25-0.81; p = 0.008) were significantly superior in the LRT group. This result was also reproduced in the multivariate analysis adjusted for α-fetoprotein, another significant prognostic factor in this study, and the well-known prognostic factors, namely the presence of main portal vein tumor thrombosis and albumin-bilirubin grade. Conclusions: The combination of lenvatinib and LRT is relatively safe and effective in increasing the intrahepatic tumor response and improving PFS and IHPFS in patients with HCC and macroscopic tumor thrombosis.
RESUMO
Cancer cachexia affects quality of life, response to chemotherapy, and survival in many advanced cancer patients. The aim of this study was to evaluate the prognostic value of pretreatment cachexia index (CXI) in patients with advanced hepatocellular carcinoma (HCC) treated with systematic chemotherapy. Patients with advanced HCC treated with lenvatinib therapy between October 2018 and October 2020 were retrospectively studied. The CXI was calculated as (L3 skeletal muscle index) × (serum albumin)/(neutrophil-to-lymphocyte ratio). The association with treatment response and early adverse events within the first two months of lenvatinib therapy was investigated. Overall survival (OS) and progression-free survival (PFS) were estimated using the Kaplan-Meier method with log-rank test. Multivariable Cox regression was used to identify the predictors of survival. A total of 116 patients (median age: 60, male: 84.5% ) with calculated CXI. They divided into two groups: high CXI (≥ 53, n = 82) and low CXI (< 53, n = 34). Patients with low CXI had a significantly lower disease control rate (61.8% vs. 89.0%, p = 0.001) and a shorter median OS (8.0 [95% CI 6.2-9.8] vs. 12.3 [95% CI 10.1-14.4] months, p = 0.002) than those with high CXI. In multivariable analysis, low CXI was independently associated with shorter OS (HR: 2.07, 95% CI: 1.17-3.65, p = 0.01) and PFS (HR: 1.84, 95% CI: 1.09-3.09, p = 0.02). Of note, during the first two months of lenvatinib therapy, anorexia (41.2% vs. 22.0%, p = 0.04) developed more frequently among patients with low CXI than those with high CXI.

Changes in the prevalence of disease over time provide valuable information from a public health perspective. We used data from Korea Military Manpower Administration medical examinations for conscription between 2003 and 2019 (n = 5,355,941), which involved young men aged 19 years, to observe changes in liver disease over time at a population level. Trends in the prevalence of hepatitis B surface antigen (HBsAg), elevated alanine aminotransferase (ALT) levels, the fibrosis-4 (FIB-4) index, obesity, and hypertension were assessed. The prevalence of HBsAg steadily decreased from 3.19% for men born in 1984 to 0.18% for men born in 2000. Among HBsAg-negative subjects, the prevalence of elevated ALT levels increased from 13.15% for men born in 1986 to 16.48% for men born in 2000. The prevalence of obesity, hypertension and the proportion with high FIB-4 scores (≥ 1.45) also increased. This population-based nationwide analysis showed a decreasing trend of HBsAg and increasing trends of possible non-alcoholic fatty liver disease.

BACKGROUND: Tenofovir disoproxil fumarate (TDF, Viread®) had been used as a standard treatment option of chronic hepatitis B (CHB). This clinical trial was conducted to evaluate the efficacy and safety of DA-2802 (tenofovir disoproxil orotate) compared to TDF. METHODS: The present study was a double blind randomized controlled trial. Patients with CHB were recruited from 25 hospitals in Korea and given DA-2802 at a dose of 319 mg once daily or Viread® at a dose of 300 mg once daily for 48 weeks from March 2017 to January 2019. Change in hepatitis B virus (HBV) DNA level at week 48 after dosing compared to baseline was the primary efficacy endpoint. Secondary efficacy endpoints were proportions of subjects with undetectable HBV DNA, those with normal alanine aminotransferase (ALT) levels, and those with loss of hepatitis B envelop antigen (HBeAg), those with loss of hepatitis B surface antigen (HBsAg). Adverse events (AEs) were also investigated. RESULTS: A total of 122 patients (DA-2802 group: n = 61, Viread® group: n = 61) were used as full analysis set for efficacy analysis. Mean age, proportion of males, laboratory results and virologic characteristics were not different between the two groups. The change in HBV DNA level at week 48 from baseline was -5.13 ± 1.40 in the DA-2802 group and -4.97 ± 1.40 log10 copies/mL in the Viread® group. The analysis of primary endpoint using the nonparametric analysis of covariance showed statistically significant results (P < 0.001), which confirmed non-inferiority of DA-2802 to Viread® by a prespecified noninferiority margin of 1. The proportion of undetectable HBV DNA was 78.7% in the DA-2802 group and 75.4% in the Viread® group (P = 0.698). The proportion of subjects who had normal ALT levels was 75.4% in the DA-2802 group and 73.3% in the Viread® group (P = 0.795). The proportion of those with HBeAg loss was 8.1% in the DA-2802 group and 10.8% in the Viread® group (P = 1.000). No subject showed HBsAg loss. The frequency of AEs during treatment was similar between the two groups. Most AEs were mild to moderate in severity. CONCLUSION: DA-2802 is considered an effective and safe treatment for patients with CHB. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT02967939.

BACKGROUND: A limited number of studies have characterized genomic properties of hepatocellular carcinoma (HCC) patients in response to anti-PD-1 immunotherapy. METHODS: Herein, we performed comprehensive molecular characterization of immediate (D-42 to D-1) pre-treatment tumor biopsy specimens from 60 patients with sorafenib-failed HCC in a single-arm prospective phase II trial of pembrolizumab. Objective response rate was the primary efficacy endpoint. We used whole-exome sequencing, RNA sequencing, and correlative analysis. In addition, we performed single-cell RNA sequencing using peripheral blood mononuclear cells. RESULTS: The overall response rate of pembrolizumab in sorafenib-failed HCC patients was 10% ([6/60] 95% CI, 2.4-17.6). In a univariate analysis using clinicopathological features, female gender, PD-L1 positivity, and low neutrophil-to-lymphocyte ratio (NLR) were identified as contributing factors to pembrolizumab response. Somatic mutations in CTNNB1 and genomic amplifications in MET were found only in non-responders. Transcriptional profiles through RNA sequencing identified that pembrolizumab responders demonstrated T cell receptor (TCR) signaling activation with expressions of MHC genes, indicating increased levels of T cell cytotoxicity. In single-cell sequencing from 10 pre- and post-treatment peripheral blood mononuclear cells (PBMCs), patients who achieved a partial response or stable disease exhibited immunological shifts toward cytotoxic CD8+ T cells. Conversely, patients with progressive disease showed an increased number of both CD14+ and CD16+ monocytes and activation of neutrophil-associated pathways. CONCLUSIONS: Taken together, HCC patients with infiltration of cytotoxic T cells, along with increased active circulating CD8+ T cells during pembrolizumab treatment and down-regulation of neutrophil-associated markers, significantly benefited from pembrolizumab treatment. TRIAL REGISTRATION: NCT#03163992 (first posted: May 23, 2017).

BACKGROUND AND AIMS: Some hepatitis B virus (HBV)-related hepatocellular carcinoma (HCC) patients show undetectable serum HBV DNA levels at HCC diagnosis. The risk of HBV reactivation and its impact on clinical outcomes are not well-unknown. METHODS: This retrospective cohort study included a total of 985 HBV-related HCC patients with undetectable serum HBV DNA levels (< 12 IU/mL) at HCC diagnosis (112 were antiviral treatment (AVT)-naïve; 873 were receiving AVT). Incidence and risk factors for HBV reactivation (re-detection of HBV DNA in serum) during follow-up, as well as its association to overall survival, were assessed. RESULTS: During a median of 33.4 months of follow-up (range: 0.2-124.2 months), HBV reactivation was observed in 279 patients. HBV reactivation rate was significantly lower for patients receiving AVT than AVT-naïve patients (three-year cumulative incidence rate: 27.3% versus 56.0%; P < 0.001). In multivariable-adjusted analysis, the risk of HBV reactivation was lower for those receiving AVT compared to AVT-naïve patients (adjusted hazard ratio: 0.39, 95% confidence interval: 0.29-0.54). Overall survival was significantly lower for those experiencing HBV reactivation than those who did not (71.5% and 85.7% at five-year) and was associated with higher risk of overall mortality (adjusted hazard ratio: 5.15, 95% confidence interval: 3.60-7.38). CONCLUSION: More than half of AVT-naïve patients experienced HBV reactivation within three years, which was associated with increased risk of overall mortality. The risk of HBV reactivation was lower for those receiving AVT, suggesting that prompt AVT needs to be considered for AVT naïve HBV-related HCC patients with undetectable HBV DNA levels.
