RESUMEN
BACKGROUND: No adjuvant treatment has been established for patients who remain at high risk for hepatocellular carcinoma recurrence after curative-intent resection or ablation. We aimed to assess the efficacy of adjuvant atezolizumab plus bevacizumab versus active surveillance in patients with high-risk hepatocellular carcinoma. METHODS: In the global, open-label, phase 3 IMbrave050 study, adult patients with high-risk surgically resected or ablated hepatocellular carcinoma were recruited from 134 hospitals and medical centres in 26 countries in four WHO regions (European region, region of the Americas, South-East Asia region, and Western Pacific region). Patients were randomly assigned in a 1:1 ratio via an interactive voice-web response system using permuted blocks, using a block size of 4, to receive intravenous 1200 mg atezolizumab plus 15 mg/kg bevacizumab every 3 weeks for 17 cycles (12 months) or to active surveillance. The primary endpoint was recurrence-free survival by independent review facility assessment in the intention-to-treat population. This trial is registered with ClinicalTrials.gov, NCT04102098. FINDINGS: The intention-to-treat population included 668 patients randomly assigned between Dec 31, 2019, and Nov 25, 2021, to either atezolizumab plus bevacizumab (n=334) or to active surveillance (n=334). At the prespecified interim analysis (Oct 21, 2022), median duration of follow-up was 17·4 months (IQR 13·9-22·1). Adjuvant atezolizumab plus bevacizumab was associated with significantly improved recurrence-free survival (median, not evaluable [NE]; [95% CI 22·1-NE]) compared with active surveillance (median, NE [21·4-NE]; hazard ratio, 0·72 [adjusted 95% CI 0·53-0·98]; p=0·012). Grade 3 or 4 adverse events occurred in 136 (41%) of 332 patients who received atezolizumab plus bevacizumab and 44 (13%) of 330 patients in the active surveillance group. Grade 5 adverse events occurred in six patients (2%, two of which were treatment related) in the atezolizumab plus bevacizumab group, and one patient (<1%) in the active surveillance group. Both atezolizumab and bevacizumab were discontinued because of adverse events in 29 patients (9%) who received atezolizumab plus bevacizumab. INTERPRETATION: Among patients at high risk of hepatocellular carcinoma recurrence following curative-intent resection or ablation, recurrence-free survival was improved in those who received atezolizumab plus bevacizumab versus active surveillance. To our knowledge, IMbrave050 is the first phase 3 study of adjuvant treatment for hepatocellular carcinoma to report positive results. However, longer follow-up for both recurrence-free and overall survival is needed to assess the benefit-risk profile more fully. FUNDING: F Hoffmann-La Roche/Genentech.

BACKGROUND & AIMS: We investigated whether baseline and on-treatment alanine aminotransferase (ALT) levels during entecavir (ETV) therapy are associated with achieving subcirrhotic liver stiffness (LS) and hepatocellular carcinoma (HCC) development in patients with hepatitis B virus (HBV)-related cirrhosis. METHODS: We analyzed data from 347 treatment-naïve patients with HBV-related cirrhosis, who started ETV between 2006 and 2011 and were followed up for >5 years without developing HCC. The study outcomes were achieving subcirrhotic LS at 5 years of ETV, and risk of HCC development beyond 5 years of ETV. Subcirrhotic LS was defined as <12 kPa by transient elastography. RESULTS: After 5 years of ETV, 227 (65.4%) patients achieved subcirrhotic LS. During a median follow-up of 9.2 years, 49 (14.1%) patients developed HCC beyond 5 years of ETV. ALT levels at baseline, at 1 year of ETV therapy, and 5 years of ETV therapy were not associated with the probability of achieving subcirrhotic LS at 5 years of ETV therapy or risk of HCC development beyond 5 years of ETV therapy (all P > .05). Patients achieving subcirrhotic LS at 5 years of ETV therapy had significantly lower risk of HCC development than those who did not (adjusted hazard ratio, 0.33; 95% confidence interval, 0.17-0.64; P = .001). CONCLUSIONS: Baseline and on-treatment ALT levels were not associated with achieving subcirrhotic LS at 5 years of ETV therapy or with risk of HCC development beyond 5 years of ETV therapy in patients with HBV-related cirrhosis. Achieving subcirrhotic LS at 5 years of ETV therapy was independently associated with lower risk of HCC development beyond 5 years of ETV therapy.

BACKGROUND & AIMS: The effect of race on routinely available noninvasive tests of fibrosis is incompletely understood. This study evaluated the performance of noninvasive tests among white and Asian patients in the STELLAR trials (NCT03053050 and NCT03053063), which evaluated selonsertib in patients with advanced (F3-F4) fibrosis due to nonalcoholic steatohepatitis (NASH). METHODS: Baseline liver biopsies were centrally read using the NASH Clinical Research Network system, and 4 noninvasive tests (Nonalcoholic fatty liver disease fibrosis score [NFS], Fibrosis-4 index [FIB-4], Enhanced Liver Fibrosis test [ELF], and liver stiffness by vibration-controlled transient elastography) were measured. The performance of these tests to discriminate advanced fibrosis was evaluated using areas under the receiver operating characteristics curves with 5-fold cross-validation repeated 100 times. RESULTS: Among 3207 patients screened with evaluable liver histology, 2281 were whites and 762 were Asians. Seventy-two percent of whites and 67% of Asians had advanced fibrosis. The areas under the receiver operating characteristics curves of the noninvasive tests for advanced fibrosis were similar in whites and Asians: 0.73 and 0.75 for NFS, 0.78 and 0.80 for FIB-4, 0.79 and 0.81 for ELF, and 0.80 and 0.83 for liver stiffness, respectively. At the published cutoffs, the tests had similar sensitivities and specificities in the 2 groups. However, the sensitivities of NFS, FIB-4, and ELF were low in both white and Asian patients younger than 40 years. CONCLUSIONS: In the global phase III STELLAR trials, the diagnostic performance of routinely available noninvasive tests for the detection of advanced fibrosis due to NASH was acceptable and similar between white and Asian patients.

BACKGROUND & AIMS: Cirrhosis and age (CAGE-B) and stiffness and age (SAGE-B) models assess the risk of hepatocellular carcinoma (HCC) development in white patients with chronic hepatitis B (CHB) undergoing sustained antiviral therapy (AVT). Herein, we checked the predictive performance of these models in Asian patients with CHB. METHODS: We reviewed 734 treatment-naive patients with CHB who started entecavir between 2006 and 2011 and were followed up for more than 5 years without HCC development during AVT. The predictive performance of CAGE-B and SAGE-B models was calculated using area under the receiver operating characteristic curves (AUROCs). RESULTS: Median liver stiffness assessed using transient elastography after 5 years of AVT was 6.8 kPa. Median CAGE-B and SAGE-B models after 5 years of AVT were 7.0 and 6.0, respectively. More than 5 years after AVT initiation, 66 patients (9.0%) developed HCC. The AUROCs of the CAGE-B and SAGE-B models were 0.764 and 0.785 after 7 years and 0.799 and 0.802 after 10 years of AVT, respectively. The cumulative incidence of HCC was significantly higher in the high-risk groups according to CAGE-B and SAGE-B risk stratification than in the medium- and low-risk groups (P < .05 in all cases). The SAGE-B model showed a higher likelihood ratio (χ2) (76.2 vs 71.4) and linear trend (χ2) (74.1 vs 58.6) than the CAGE-B model, whereas the CAGE-B model showed higher Akaike information criteria (64.3 vs 50.3). CONCLUSIONS: Both SAGE-B and CAGE-B showed acceptable performance in predicting HCC after 5 years of AVT in Asian patients with CHB.

BACKGROUND AND AIM: Antiviral therapy (AVT) induces fibrosis regression in patients with chronic hepatitis B. We investigated long-term effects of entecavir (ETV) versus tenofovir (TDF) on fibrotic burden. METHODS: Treatment-naïve chronic hepatitis B patients who had begun ETV or TDF were recruited from four tertiary hospitals. The aspartate aminotransferase-to-platelet ratio index (APRI) and fibrosis index based on four factors (FIB-4) were used to determine fibrotic burden. RESULTS: In the entire population (n = 3277), although patients treated with ETV had higher baseline APRI (1.71 vs 1.07, P < 0.001) and FIB-4 (3.60 vs 2.80, P < 0.001) than those treated with TDF, significant fibrosis regression was identified during 6 years of AVT in both ETV (APRI, mean 1.71 â 0.48, P < 0.001; FIB-4, mean 3.60 â 2.21, P < 0.001) and TDF groups (APRI, mean 1.07 â 0.43, P < 0.001; FIB-4, mean 2.80 â 2.19, P < 0.001). In patients without cirrhosis (n = 2366), baseline APRI was significantly higher in ETV group than in TDF group (1.72 vs 0.97, P < 0.001); however, they became similar after 6 months. Similarly, baseline FIB-4 was significantly higher in ETV group than in TDF group (3.25 vs 2.35, P < 0.001), but became similar from 4 to 6 years. In patients with cirrhosis (n = 911), baseline APRI (1.70 vs 1.34, P < 0.001) and FIB-4 (4.62 vs 3.91, P = 0.005) were higher in ETV group than in TDF, however, both parameters became statistically similar from 6 months to 6 years. CONCLUSION: Significant regression of APRI and FIB-4 was observed during long-term ETV and TDF treatment. Despite higher baseline fibrotic burden in ETV group, fibrotic burden between the groups eventually converged through significant fibrosis regression after 1 to 4 years of AVT.

Several prediction scores for the early detection of hepatocellular carcinoma (HCC) are available. We validated the predictive accuracy of age, albumin, sex, liver cirrhosis (AASL), RESCUE-B, PAGE-B and modified PAGE-B (mPAGE-B) scores in chronic hepatitis B (CHB) patients treated with entecavir (ETV) or tenofovir disoproxil fumarate (TDF). Between 2007 and 2014, 3171 patients were recruited (1645, ETV; 1517, TDF). The predictive accuracy of each prediction score was assessed. The mean age of the study population (1977 men; 1194 women) was 48.8 years. Liver cirrhosis was present in 1040 (32.8%) patients. During follow-up (median, 58.2 months), 280 (8.8%) patients developed HCC; these patients were significantly older; more likely to be male; had significantly higher proportions of liver cirrhosis, hypertension and diabetes; and had significantly higher values for the four risk scores than those who did not develop HCC (all P < .05). Older age (hazard ratio [HR] = 1.048), male sex (HR = 2.142), liver cirrhosis (HR = 3.144) and prolonged prothrombin time (HR = 2.589) were independently associated with an increased risk of HCC (all P < .05), whereas a higher platelet count (HR = 0.996) was independently associated with a decreased risk of HCC (P < .05). The predictive accuracy of AASL score was the highest for 3- and 5-year HCC predictions (areas under the curve [AUCs] = 0.818 and 0.816, respectively), followed by RESCUE-B, PAGE-B and mPAGE-B scores (AUC = 0.780-0.815 and 0.769-0.814, respectively). In conclusion, four HCC prediction scores were assessed in Korean CHB patients treated with ETV or TDF. The AASL score showed the highest predictive accuracy.

BACKGROUND AND AIMS: The influence of direct-acting antivirals (DAAs) on chronic hepatitis C (CHC)-related hepatocellular carcinoma (HCC) remains controversial. We investigated the effect of eradicating CHC using DAAs on treatment outcomes in patients with CHC-related HCC treated with transarterial chemoembolization (TACE). METHODS: This nationwide, multi-center, retrospective study recruited patients with CHC-related HCC treated with TACE as the first-line anti-cancer treatment, and who achieved a sustained virological response (SVR) using DAAs (DAA group) between 2006 and 2017. Patients achieving an SVR following interferon-based treatment (IFN group) and those without treatment (control group) were also recruited for comparison. RESULTS: A total of 425 patients were eligible for the study. Of these, 356 (83.8%), 26 (6.1%), and 43 (10.1%) were allocated to the control, IFN, and DAA groups, respectively. A multivariate analysis showed that liver cirrhosis, segmental portal vein thrombosis, and larger maximal tumor size independently predicted an increased risk of progression (all p < 0.05), whereas, the DAA group (vs. IFN and control groups) independently predicted a reduced risk of progression (hazard ratio (HR) = 0.630, 95% confidence interval 0.411-0.966, p = 0.034). The cumulative incidence rate of HCC progression in the DAA group was significantly lower than that in the IFN and control groups (p = 0.033, log-rank test). In addition, the DAA group (vs. IFN and control groups) was independently associated with a reduced risk of mortality (p = 0.042). CONCLUSIONS: DAA treatment provided significantly prolonged progression-free survival in patients with CHC-related HCC treated with TACE compared to that in patients administered IFN or no treatment.

BACKGROUND: Since September 2015, the initiation of antiviral therapy (AVT) for patients with chronic hepatitis B (CHB)-related cirrhosis has been reimbursed according to the revised Korean Association for the Study of Liver (KASL) guideline, if the patient had hepatitis B virus DNA level ≥ 2,000 IU/L, regardless of aminotransferase or alanine aminotransferase levels. This study investigated whether the KASL guideline implementation reduced the risk of CHB-related hepatocellular carcinoma (HCC) in patients with cirrhosis in South Korea. METHODS: A total of 429 patients with CHB-related cirrhosis who initiated AVT between 2014 and 2016 were recruited. The risk of HCC development was compared between patients who initiated AVT before and after September 2015 (pre-guideline [n = 196, 45.7%] vs. post-guideline implementation [n = 233, 54.3%]). RESULTS: Univariate analysis showed that AVT initiation before guideline implementation, older age, male gender, and diabetes significantly predicted increased risk of HCC development (all P < 0.05). Subsequent multivariate analysis showed that AVT initiation before guideline implementation (HR = 1.941), older age (HR = 5.762), male gender (HR = 2.555), and diabetes (HR = 1.568) independently predicted increased risk of HCC development (all P < 0.05). Additionally, multivariate analysis showed that AVT initiation before guideline implementation (HR = 2.309), male gender (HR = 3.058), and lower platelet count (HR = 0.989) independently predicted mortality (P < 0.05). The cumulative incidences of HCC and mortality were significantly higher in patients who initiated AVT before guideline implementation than in those who initiated AVT after guideline implementation (all P < 0.05, log-rank test). CONCLUSION: The prognosis of patients with CHB-related cirrhosis who initiated AVT improved after guideline implementation according to the revised KASL guideline.

BACKGROUND & AIMS: Researchers previously developed a scoring system to determine the risk of hepatocellular carcinoma (HCC) in patients with chronic hepatitis B virus (HBV) infection, based on the presence of cirrhosis, patient age, male sex, and diabetes (called the CAMD scoring system). We validated the CAMD scoring system and compared its performance with that of other risk assessment models in an independent cohort. METHODS: We followed up 3277 patients with chronic HBV infection (mean age, 48.7 y; 62.6% male; 32.4% with cirrhosis) who were treated with entecavir (n = 1725) or tenofovir (n = 1552) as the first-line antiviral agent in 4 academic teaching hospitals in the Republic of Korea. The primary outcome was development of HCC. We evaluated the ability of the CAMD, PAGE-B, and mPAGE-B scoring systems to identify patients who would develop HCC using integrated area under the curve (iAUC) analysis. RESULTS: Over a median follow-up period of 58.2 months, 8.9% of the patients developed HCC. Patients who developed HCC were older, more likely to be male, and had higher proportions of cirrhosis and diabetes than patients who did not develop HCC (all P < .05). CAMD scores identified patients who developed HCC with an iAUC of 0.790, mPAGE-B scores with an iAUC of 0.769, and PAGE-B scores with an iAUC of 0.760. The 5-year cumulative risks of HCC were 1.3% in patients with low CAMD scores (<8), 8.0% in patients with intermediate CAMD scores (8-13), and 24.3% in patients with high CAMD scores (>13) (P < .001 for comparison of low- vs intermediate-score groups and between intermediate- vs high-score groups). The predicted and observed probabilities of HCC had excellent agreement. CONCLUSIONS: We validated the CAMD scoring system in determining the risk of HCC in patients with chronic HBV treatment receiving entecavir or tenofovir treatment. Validation was performed in a cohort of patients in the Republic of Korea, where most patients have genotype C2 HBV infection.

The risk of developing hepatitis B virus (HBV)-related hepatocellular carcinoma (HCC) is reduced by antiviral therapy. Here, we evaluated the chronological trends in HCC development risk starting in 2007, when entecavir reimbursement was first initiated in South Korea. Treatment-naïve patients with chronic hepatitis B (CHB) receiving entecavir 0.5 mg/d were stratified into three groups according to entecavir start time: early (2007-2010), middle (2011-2012) and late (2013-2014) cohorts Among 2442 patients, cumulative probabilities of developing HCC after 1, 3 and 5 years were, respectively, 1.7%, 5.1%, and 8.2% (early cohort; n = 672); 1.5%, 5.1% and 8.9% (middle cohort; n = 757); and 1.2%, 5.3% and 10.6% (late cohort; n = 1013; P > .05 between each pair). Older age, male, positive hepatitis B e antigen, liver cirrhosis, Child-Pugh class B (vs A) and lower platelet count significantly predicted HCC development in univariate analysis (P < .001), whereas entecavir start time (early vs middle vs late cohorts) did not affect the risk of HCC development (P = .457). A multivariate analysis revealed that older age (adjusted hazard ratio [aHR]=1.041), male gender (aHR = 2.069), liver cirrhosis (aHR = 3.771) and Child-Pugh class B (vs A, aHR = 1.548) were independently associated with an increased risk of HCC development, whereas higher platelet count was independently associated with a reduced risk of HCC development (aHR = 0.993; all P < .05). In conclusion, the risk of developing HCC among patients receiving entecavir in South Korea has been stable since 2007. To establish more effective HCC surveillance programs, further studies regarding the carcinogenic roles of nonviral factors are required.

The risk of developing hepatocellular carcinoma (HCC) after hepatitis B e antigen seroclearance (ESC) remains unclear. We established and validated a new risk prediction model for HCC development after ESC in patients with chronic hepatitis B (CHB) receiving antiviral therapy (AVT). Between 2006 and 2016, 769 patients (training cohort) and 1,061 patients (validation cohort) with CHB who experienced ESC during AVT using entecavir (ETV) or tenofovir disoproxil fumarate (TDF) were recruited. In the multivariate analysis, male sex (hazard ratio [HR] = 2.092; 95% confidence interval [CI] = 1.152-3.800), cirrhosis (HR = 5.141; 95% CI = 2.367-11.167) and fibrosis-4 index (FIB-4) of >3.25 (HR = 2.070; 95% CI = 1.184-3.620) were the independent risk factors for HCC development (all P < .05). Accordingly, a novel HCC-ESCAVT model was developed (1x[sex: male = 1, female = 0] + 3x(cirrhosis = 1, noncirrhosis = 0) + 1x(FIB-4: >3.25 = 1, ≤3.25 = 0). The cumulative risk for HCC development was significantly different among the risk groups based on the HCC-ESCAVT category (0-1, 2-4 and 5 for the low-, intermediate- and high-risk groups, respectively) (overall P < .001, log-rank test). The area under the receiver operating characteristic curve (AUC) for predicting HCC development 3, 5 and 10 years after ESC was 0.791, 0.771 and 0.790, respectively (all P < .05). The predictive value of the HCC-ESCAVT model was similar in the validation cohort (AUC = 0.802, 0.774 and 0.776 at 3, 5 and 10 years, respectively; all P < .05). Hence, we have developed and validated a new HCC-ESCAVT model for HCC development, which includes male sex, cirrhosis and FIB-4 of >3.25 as constituent variables.

Acute liver failure (ALF) caused by hepatitis A is a rare but fatal disease. Here, we developed a model to predict outcome in patients with ALF caused by hepatitis A. The derivation set consisted of 294 patients diagnosed with hepatitis A-related ALF (ALFA) from Korea, and a validation set of 56 patients from Japan, India, and United Kingdom. Using a multivariate proportional hazard model, a risk-prediction model (ALFA score) consisting of age, international normalized ratio, bilirubin, ammonia, creatinine, and hemoglobin levels acquired on the day of ALF diagnosis was developed. The ALFA score showed the highest discrimination in the prediction of liver transplant or death at 1 month (c-statistic, 0.87; 95% confidence interval [CI], 0.84-0.92) versus King's College criteria (KCC; c-statistic, 0.56; 95% CI, 0.53-0.59), U.S. Acute Liver Failure Study Group index specific for hepatitis A virus (HAV-ALFSG; c-statistic, 0.70; 95% CI, 0.65-0.76), the new ALFSG index (c-statistic, 0.79; 95% CI, 0.74-0.84), Model for End-Stage Liver Disease (MELD; c-statistic, 0.79; 95% CI, 0.74-0.84), and MELD including sodium (MELD-Na; c-statistic, 0.78; 95% CI, 0.73-0.84) in the derivation set (all P < 0.01). In the validation set, the performance of the ALFA score (c-statistic, 0.84; 95% CI, 0.74-0.94) was significantly better than that of KCC (c-statistic, 0.65; 95% CI, 0.52-0.79), MELD (c-statistic, 0.74; 95% CI, 0.61-0.87), and MELD-Na (c-statistic, 0.72; 95% CI, 0.58-0.85) (all P < 0.05), and better, but not statistically significant, than that of the HAV-ALFSG (c-statistic, 0.76; 95% CI, 0.61-0.90; P = 0.28) and new ALFSG indices (c-statistic, 0.79; 95% CI, 0.65-0.93; P = 0.41). The model was well-calibrated in both sets. Conclusion: Our disease-specific score provides refined prediction of outcome in patients with ALF caused by hepatitis A.

BACKGROUND: Liver cirrhosis has become a heavy burden not only for patients, but also for our society. However, little is known about the recent changes in clinical outcomes and characteristics of patients with cirrhosis-related complications in Korea. Therefore, we aimed to evaluate changes in characteristics of patients with liver cirrhosis in Daegu-Gyeongbuk province in Korea over the past 15 years. METHODS: We retrospectively reviewed the medical records of 15,716 liver cirrhotic patients from 5 university hospitals in Daegu-Gyeongbuk province from 2000 to 2014. The Korean Standard Classification of Diseases-6 code associated with cirrhosis was investigated through medical records and classified according to the year of first visit. RESULTS: A total of 15,716 patients was diagnosed with cirrhosis. A number of patients newly diagnosed with cirrhosis has decreased each year. In 2000, patients were most likely to be diagnosed with hepatitis B virus (HBV) cirrhosis, followed by alcoholic cirrhosis. There was a significant decrease in HBV (P < 0.001), but alcohol, hepatitis C virus (HCV), and non-alcoholic fatty liver disease (NAFLD) showed a significant increase during the study period (alcohol, P = 0.036; HCV, P = 0.001; NAFLD, P = 0.001). At the time of initial diagnosis, the ratio of Child-Turcotte-Pugh (CTP) class A gradually increased from 23.1% to 32.9% (P < 0.001). The most common cause of liver-related hospitalization in 2000 was hepatocellular carcinoma (HCC) (25.5%); in 2014, gastrointestinal bleeding with esophageal and gastric varices (21.4%) was the most common cause. Cases of hospitalization with liver-related complication represented 76.4% of all cases in 2000 but 70.9% in 2014. Incidence rate of HCC has recently increased. In addition, HCC-free survival was significantly lower in CTP class A than in classes B and C. Finally, there was significant difference in HCC occurrence according to causes (P < 0.001). HBV and HCV cirrhosis had lower HCC-free survival than alcoholic and NAFLD cirrhosis. CONCLUSION: In recent years, the overall number of cirrhosis patients has decreased. This study confirmed the recent trend in decrease of cirrhosis, especially of cirrhosis due to HBV, and the increase of HCV, alcoholic and NAFLD cirrhosis. Targeted screening for at-risk patients will facilitate early detection of liver diseases allowing effective intervention and may have decreased the development of cirrhosis and its complications.

Exosomal noncoding RNAs (ncRNAs) have unique expression profiles reflecting the characteristics of a tumor, and their role in tumor progression and metastasis is emerging. However, the significance of circulating exosomal ncRNAs in the prognosis of hepatocellular carcinoma (HCC) remains to be elucidated. We therefore determined the prognostic significance of circulating exosomal ncRNAs (miRNA-21 and lncRNA-ATB) for human HCC. This prospective study enrolled 79 HCC patients between October 2014 and September 2015. Exosomes were extracted from serum samples using the ExoQuick Exosome Precipitation Solution. To validate the isolation of the exosomes from serum, immunoblotting for exosome markers and characterization of nanoparticle using NanoSight were performed. NcRNAs were isolated from exosomes using the miRNeasy serum/plasma micro kit. Both circulating exosomal miRNA-21 and lncRNA-ATB were related to TNM stage and other prognostic factors, including the T stage and portal vein thrombosis. Multivariate analysis using the Cox regression test identified that both higher miRNA-21 and higher lncRNA-ATB were independent predictors of mortality and disease progression, along with larger tumor size and higher C-reactive protein (all p < 0.05). The overall survival and progression-free survival were significantly lower in patients with higher circulating levels of exosomal miRNA-21 (≥0.09) and lncRNA-ATB (≥0.0016) (log-rank test: p < 0.05). In conclusion, our study has provided strong evidence that circulating exosomal ncRNAs (miRNA-21 and lncRNA-ATB) are novel prognostic markers and therapeutic targets for HCC.

BACKGROUND & AIMS: It is currently unclear which antiviral agent, entecavir (ETV) or tenofovir disoproxil fumarate (TDF), is superior for improving prognosis in patients with chronic hepatitis B (CHB). Here, we assessed the ability of these 2 antivirals to prevent liver-disease progression in treatment-naïve patients with CHB. METHODS: From 2012 to 2014, treatment-naïve patients with CHB who received ETV or TDF as a first-line antiviral agent were recruited from 4 academic teaching hospitals. Patients with decompensated cirrhosis or hepatocellular carcinoma (HCC) at enrollment were excluded. Cumulative probabilities of HCC and death or orthotopic liver transplant (OLT) were assessed. RESULTS: In total, 2,897 patients (1,484 and 1,413 in the ETV and TDF groups, respectively) were recruited. The annual HCC incidence was not statistically different between the ETV and TDF groups (1.92 vs. 1.69 per 100 person-years [PY], respectively; adjusted hazard ratio [HR] 0.975 [pâ¯=â¯0.852] by multivariate analysis). Propensity score (PS)-matched and inverse probability of treatment weighting (ITPW) analyses yielded similar patterns of results (HR 1.021 [pâ¯=â¯0.884] and 0.998 [pâ¯=â¯0.988], respectively). The annual incidence of death or OLT was not statistically different between the ETV and TDF groups (0.52 vs. 0.53 per 100 PY, respectively; adjusted HR 1.202 [pâ¯=â¯0.451]). PS-matched and ITPW analyses yielded similar patterns of results (HR 1.248 [pâ¯=â¯0.385] and 1.239 [pâ¯=â¯0.360], respectively). These findings were consistently reproduced in patients with compensated cirrhosis (all p >0.05). CONCLUSIONS: The overall prognosis in terms of HCC and death or OLT was not statistically different between the ETV and TDF groups. Further studies are needed to validate our results. LAY SUMMARY: It is currently unclear which antiviral agent, entecavir or tenofovir disoproxil fumarate, is superior for improving prognosis in patients with chronic hepatitis B virus infection. In this analysis we found that there was no difference in terms of overall prognosis, including risk of hepatocellular carcinoma, death, or the need for a liver transplant, in patients receiving either antiviral.

BACKGROUND & AIMS: Patients with thrombocytopenia and chronic liver disease (CLD) may require platelet transfusions before scheduled procedures to decrease risk of bleeding. We performed 2 randomized, placebo-controlled, phase 3 trials in patients with thrombocytopenia and CLD undergoing scheduled procedures to evaluate the safety and efficacy of avatrombopag in increasing platelet counts in this patient population. METHODS: In the ADAPT-1 and ADAPT-2 studies, adults with thrombocytopenia and CLD (n = 231 and n = 204, respectively) were in 1 of 2 cohorts according to their baseline platelet count (below 40 × 109/L or 40 to below 50 × 109/L) and within each cohort were randomized (2:1) to receive 5 daily doses of avatrombopag (60 mg if baseline platelet count below 40 × 109/L or 40 mg if 40 to below 50 × 109/L) or placebo. ADAPT-1 was conducted at 75 study sites in 20 countries, from February 2014 through January 2017, and ADAPT-2 was conducted at 74 sites in 16 countries, from December 2013 through January 2017. The primary endpoint was the proportion of patients not requiring platelet transfusions or rescue procedures for bleeding up to 7 days after a scheduled procedure. RESULTS: In the ADAPT-1 study, 65.6% of patients who received 60 mg avatrombopag and 88.1% of patients who received 40 mg avatrombopag met the primary endpoint compared with 22.9% and 38.2% of patients receiving placebo, respectively (P < .0001 for both). In the ADAPT-2 study, 68.6% of patients who received 60 mg avatrombopag and 87.9% of patients who received 40 mg avatrombopag met the primary endpoint compared with 34.9% and 33.3% of patients who received placebo, respectively (P < .001 for both). Avatrombopag led to a measured increase in platelet counts and increased the proportion of patients who achieved the target platelet count ≥ 50 × 109/L on procedure day vs placebo. The incidence and severity of adverse events were similar for the avatrombopag and placebo groups and were consistent with those expected in the CLD population. CONCLUSIONS: In 2 phase 3 randomized trials, avatrombopag was superior to placebo in reducing the need for platelet transfusions or rescue procedures for bleeding in patients with thrombocytopenia and CLD undergoing a scheduled procedure.

Hepatitis B virus (HBV) suppression with nucleot(s)ide analogue therapy reduces the risk of hepatic decompensation and hepatocellular carcinoma (HCC) in patients with advanced liver disease.1 In the present era of potent antiviral therapies, the prognostic significance of the serum HBV DNA level as a biological gradient has substantially diminished; the majority of treated patients achieve virologic suppression.2,3 After control of viremia, a higher baseline fibrosis level is a useful predictor for disease progression.4 Few "prospective" studies on the effects of antiviral agents, especially in chronic hepatitis B (CHB) patients with advanced liver disease, have been reported.

RESUMEN
BACKGROUND & AIMS: Little is known about the effects of antiviral therapy on short- and long-term survival of patients with hepatitis B virus (HBV)-related decompensated cirrhosis. We aimed to determine whether a maintained virologic response (MVR, defined as persistent undetectable HBV DNA during therapy) associates with short-term (6 mo) and long-term (6-120 mo) survival of patients with decompensated cirrhosis. METHODS: We performed a 10-year observation analysis using data from the Epidemiology and Natural History of Liver Cirrhosis study of patients with decompensated liver cirrhosis in Korea. Of the entire cohort (1595 patients enrolled at onset of decompensation since 2005), our analysis comprised 295 patients who immediately began treatment with entecavir (n = 179) or lamivudine (n = 116) after decompensation. We collected laboratory test results, data on hepatocellular carcinoma (HCC) development, and Child-Turcotte-Pugh and model for end-stage liver disease (MELD) scores. The mean follow-up time was 62.3 ± 36.5 months. The primary end point was time of liver transplant-free survival. RESULTS: The median survival time was 7.7 years; 60.1% of patients survived for 5 years and 45.7% survived for 10 years without liver transplantation. An MVR was observed in 116 patients (39.3%); these patients had significantly longer times of transplant-free survival than patients without MVR. Survival times associated with the occurrence of HCC; survival of patients without HCC was excellent if they survived the first 6 months after initiation of antiviral therapy, whereas the survival rates of patients with HCC decreased persistently over time. A baseline MELD score above 20 and multiple complications were associated with short-term mortality. MVR was the factor most strongly associated with long-term transplant-free survival. Significantly higher proportions of patients who received entecavir survived 10 years compared with patients who received lamivudine, but no difference was observed among patients with MVRs. Patients with MVRs had significant improvement in hepatic function over time, but nonsignificant reductions in risk of HCC or HCC-related mortality. CONCLUSIONS: In a 10-year observation study of patients in Korea with HBV-related decompensated cirrhosis, we found baseline MELD score and MVR to entecavir or lamivudine to associate with short- and long-term transplant-free survival. The benefits of an MVR are maintained for up to 10 years even after decompensation, but patients are still at risk for HCC.

PURPOSE: Resminostat is an oral inhibitor of class I, IIB, and IV histone deacetylases. This phase I/II study compared the safety and efficacy of resminostat plus sorafenib versus sorafenib monotherapy as first-line therapy for advanced hepatocellular carcinoma (HCC). EXPERIMENTAL DESIGN: In phase I, resminostat (400 mg or 600 mg/day on days 1 to 5 every 14 days) was administered with sorafenib (800 mg/day for 14 days) to determine the recommended dose for phase II. In phase II, patients were randomized (1:1) to sorafenib monotherapy or resminostat plus sorafenib. The primary endpoint was time-to-progression (TTP). RESULTS: Nine patients (3: 400 mg, 6: 600 mg) were enrolled in phase I, and the recommended dose of resminostat was determined to be 400 mg/day. Then 170 patients were enrolled in phase II. Median TTP/overall survival (OS) were 2.8/14.1 months with monotherapy versus 2.8/11.8 months with combination therapy (Hazard Ratio [HR]: 0.984, p = 0.925/HR: 1.046, p = 0.824). The overall incidence of adverse events was similar in both groups (98.8% versus 100.0%). However, thrombocytopenia ≥ Grade 3 was significantly more frequent in the combination therapy group (34.5% versus 2.4%, p < 0.001). Subgroup analysis revealed that median TTP/OS was 1.5/6.9 months for monotherapy versus 2.8/13.1 months for combination therapy (HR: 0.795, p = 0.392/HR: 0.567, p = 0.065) among patients with a normal-to-high baseline platelet count (≥ 150 × 103/mm3). CONCLUSIONS: In patients with advanced HCC, first-line therapy with resminostat at the recommended dose plus sorafenib showed no significant efficacy advantage over sorafenib monotherapy.
