RESUMEN
The proto-oncogene MYCN expression marked a cancer stem-like cell population in hepatocellular carcinoma (HCC) and served as a therapeutic target of acyclic retinoid (ACR), an orally administered vitamin A derivative that has demonstrated promising efficacy and safety in reducing HCC recurrence. This study investigated the role of MYCN as a predictive biomarker for therapeutic response to ACR and prognosis of HCC. MYCN gene expression in HCC was analyzed in the Cancer Genome Atlas and a Taiwanese cohort (N = 118). Serum MYCN protein levels were assessed in healthy controls (N = 15), patients with HCC (N = 116), pre- and post-surgical patients with HCC (N = 20), and a subset of patients from a phase 3 clinical trial of ACR (N = 68, NCT01640808). The results showed increased MYCN gene expression in HCC tumors, which positively correlated with HCC recurrence in non-cirrhotic or single-tumor patients. Serum MYCN protein levels were higher in patients with HCC, decreased after surgical resection of HCC, and were associated with liver functional reserve and fibrosis markers, as well as long-term HCC prognosis (>4 years). Subgroup analysis of a phase 3 clinical trial of ACR identified serum MYCN as the risk factor most strongly associated with HCC recurrence. Patients with HCC with higher serum MYCN levels after a 4-week treatment of ACR exhibited a significantly higher risk of recurrence (hazard ratio 3.27; p = .022). In conclusion, serum MYCN holds promise for biomarker-based precision medicine for the prevention of HCC, long-term prognosis of early-stage HCC, and identification of high-response subgroups for ACR-based treatment.

BACKGROUND & AIMS: It is unclear if there may be sex differences in response to nucleos(t)ide analogs including virologic response (VR), biochemical response (BR), complete response (CR), and hepatocellular carcinoma (HCC) incidence among hepatitis B patients. We compared nucleos(t)ide analog treatment outcomes by sex. METHODS: We performed a retrospective cohort study of 3388 treatment-naïve adult hepatitis B patients (1250 female, 2138 male) from the Real-World Evidence from the Global Alliance for the Study of Hepatitis B Virus consortium who initiated therapy with either entecavir or tenofovir from 22 sites (Argentina, Korea, Japan, Taiwan, and the United States). We used propensity-score matching to balance background characteristics of the male and female groups and competing-risks analysis to estimate the incidence and subdistribution hazard ratios (SHRs) of VR, BR, CR, and HCC. RESULTS: Females (vs males) were older (52.0 vs 48.6 y); less likely to be overweight/obese (49.3% vs 65.7%), diabetic (9.9% vs 13.1%), or cirrhotic (27.9% vs 33.0%); and had a lower HBV DNA level (5.9 vs 6.0 log10 IU/mL) and alanine aminotransferase level (91 vs 102 IU/L) (all P < .01). However, after propensity-score matching, relevant background characteristics were balanced between the 2 groups. Females (vs males) had similar 5-year cumulative VR (91.3% vs 90.3%; P = .40) and HCC incidence rates (5.1% vs 4.4%; P = .64), but lower BR (84.0% vs 90.9%; P < .001) and CR (78.8% vs 83.4%; P = .016). Males were more likely to achieve BR (SHR, 1.31; 95% CI, 1.17-1.46; P < .001) and CR (SHR, 1.16; 95% CI, 1.03-1.31; P = .016), but VR and HCC risks were similar. CONCLUSIONS: Sex differences exist for treatment outcomes among hepatitis B patients. Male sex was associated with a 16% higher likelihood of clinical remission and a 31% higher likelihood of biochemical response than females, while virologic response and HCC incidence were similar between the 2 groups.

BACKGROUND: Although the combination of atezolizumab and bevacizumab (ATZ + BEV) is a standard treatment for advanced hepatocellular carcinoma (HCC), strategies for addressing treatment failure and prognostic factors of post-progression survival (PPS) remain unestablished. METHODS: We conducted a multicentre retrospective study to evaluate PPS following ATZ + BEV treatment in patients with advanced HCC. We classified the patients into three groups: BCLC stage B and BCLC stage C without or with new extrahepatic lesions (BCLCp-C1 and BCLCp-C2, respectively) at the time of progression. RESULTS: Of the 204 patients who started ATZ + BEV treatment between October 2020 and September 2022, 110 showed disease progression, with 33, 55 and 22 showing the BCLCp-B, BCLCp-C1 and BCLCp-C2 stages of the disease, respectively. Specifically, patients with the BCLCp-B stage of the disease showed better overall survival than those with the BCLCp-C1 and BCLCp-C2 stages (hazard ratios: 1.93 [95% confidence interval, CI, 1.06-3.51] and 2.64 [95% CI, 1.32-5.30] for HCC stages BCLCp-C1 and BCLCp-C2, respectively). Via multivariable analysis, we identified the BCLCp-C1 and BCLCp-C2 stages, as well as performance status, Child-Pugh class and alpha-fetoprotein as poor prognostic factors for PPS. CONCLUSIONS: BCLCp-B1 stage was identified as a better prognostic factor for PPS following ATZ + BEV treatment compared with BCLCp-C1 and BCLCp-C2 stages. This may help in making decisions regarding subsequent treatment after ATZ + BEV.

AIM: An association between hepatitis B core-related antigen (HBcrAg) kinetics and hepatocarcinogenesis during nucleoside (t)id analog (NA) treatment has recently been reported. HBcrAg kinetics and factors associated with HBcrAg response during tenofovir alafenamide (TAF) administration remain unclear. In this multicenter retrospective study, we aimed to clarify the efficacy and safety of TAF in treatment-naïve patients with chronic hepatitis B, focusing on the reduction in HBcrAg levels. METHODS: Patients were treated with TAF monotherapy for 96 weeks, and the kinetics of HBcrAg during treatment and the factors associated with HBcrAg response (defined as a change in HBcrAg of -1 log IU/mL from baseline) were evaluated. RESULTS: The study population comprised 241 patients, 36.9% of whom were HBeAg-positive. The median baseline HBcrAg level was 4.7 log IU/mL. The median change in HBcrAg from baseline was -1.1 log IU/mL at 96 weeks after treatment. The HBcrAg response rate at 96 weeks was 56.6% (43/76). Multivariate analysis revealed high alanine transaminase level as an independent baseline factor associated with HBcrAg response at 96 weeks of treatment (p = 4.53 × 10-6). No correlation was found between the HBcrAg and hepatitis B surface antigen kinetics in patients treated with TAF monotherapy. CONCLUSIONS: In TAF monotherapy for patients with chronic hepatitis B, HBcrAg levels were significantly decreased and baseline alanine transaminase level is an important factor associated with HBcrAg reduction. As no correlation was found between HBcrAg and reduced hepatitis B surface antigen levels in this study, HBcrAg kinetics in addition to hepatitis B surface antigen may need to be monitored during TAF treatment.
RESUMEN
AIM: This study aims to evaluate the efficacy and safety of lenvatinib radiofrequency ablation (RFA) sequential therapy for certain hepatocellular carcinoma (HCC) patients. METHODS: One hundred and nineteen patients with unresectable HCC in the intermediate stage with Child-Pugh A were retrospectively recruited in a multicenter setting. Those in the lenvatinib RFA sequential therapy group received lenvatinib initially, followed by RFA and the retreatment with lenvatinib. The study compared overall survival (OS), progression-free survival (PFS), tumor response, and adverse events (AEs) between patients undergoing sequential therapy and lenvatinib monotherapy. RESULTS: After propensity score matching, 25 patients on sequential therapy and 50 on monotherapy were evaluated. Independent factors influencing OS were identified as sequential therapy, modified albumin-bilirubin (mALBI) grade, and relative dose intensity (%) with hazard ratios (HRs) of 0.381 (95% confidence interval [CI], 0.186-0.782), 2.220 (95% CI, 1.410-3.493), and 0.982 (95% CI, 0.966-0.999), respectively. Stratified analysis based on mALBI grades confirmed the independent influence of treatment strategy across all mALBI grades for OS (HR, 0.376; 95% CI, 0.176-0.804). Furthermore, sequential therapy was identified as an independent factor of PFS (HR, 0.382; 95% CI, 0.215-0.678). Sequential therapy significantly outperformed monotherapy on survival benefits (OS: 38.27 vs. 18.96 months for sequential therapy and monotherapy, respectively, p = 0.004; PFS: 13.80 vs. 5.32 months for sequential therapy and monotherapy, respectively, p < 0.001). Sequential therapy was significantly associated with complete response by modified Response Evaluation Criteria in Solid Tumors (odds ratio, 63.089). Ten of 119 patients experienced grade 3 AEs, with no AE beyond grade 3 observed. CONCLUSION: Lenvatinib RFA sequential therapy might offer favorable tolerability and potential prognostic improvement compared to lenvatinib monotherapy.
RESUMEN
BACKGROUND AND AIM: While several predictive models for the development of hepatocellular carcinoma (HCC) have been proposed, including those for patients with chronic hepatitis C virus (HCV) infection who have achieved sustained virologic response (SVR), the best model may differ between regions. We compared the ability of six reported models to stratify the risk of post-SVR HCC in Japan, where rigorous surveillance and early detection of HCC is common. METHODS: A total of 6048 patients with no history of HCC who achieved SVR by oral direct-acting antiviral drugs were enrolled in this nationwide study. Patients continued HCC surveillance every 6 months after SVR. The incidence of post-SVR HCC was compared between risk groups using the aMAP score, FIB-4 index, Tahata model, GAF4 criteria, GES score, and ADRES score. RESULTS: During the observation period with a median duration of 4.0 years after SVR, post-SVR HCC developed in 332 patients (5.5%). All six models performed significantly at stratifying the incidence of HCC. However, Harrell's C-index was below 0.8 for all models (range, 0.660-0.748), indicating insufficient stratification ability. CONCLUSION: Although all six proposed models demonstrated a good ability to predict the development of post-SVR HCC, their ability to stratify the risk of post-SVRHCC was unsatisfactory. Further studies are necessary to identify the best model for assessing the risk of post-SVR HCC in regions where early detection of HCC is common.

BACKGROUND AND AIM: The benefits of entecavir (ETV) versus tenofovir disoproxil fumarate (TDF) in reducing the development of chronic hepatitis B (CHB)-related hepatocellular carcinoma remain controversial. Whether mortality rates differ between patients with CHB treated with ETV and those treated with TDF is unclear. METHODS: A total of 2542 patients with CHB treated with either ETV or TDF were recruited from a multinational cohort. A 1:1 propensity score matching was performed to balance the differences in baseline characteristics between the two patient groups. We aimed to compare the all-cause, liver-related, and non-liver-related mortality between patients receiving ETV and those receiving TDF. RESULTS: The annual incidence of all-cause mortality in the entire cohort was 1.0/100 person-years (follow-up, 15 757.5 person-years). Patients who received TDF were younger and had a higher body mass index, platelet count, hepatitis B virus deoxyribonucleic acid levels, and proportion of hepatitis B e-antigen seropositivity than those who received ETV. The factors associated with all-cause mortality were fibrosis-4 index > 6.5 (hazard ratio [HR]/confidence interval [CI]: 3.13/2.15-4.54, P < 0.001), age per year increase (HR/CI: 1.05/1.04-1.07, P < 0.001), alanine aminotransferase level per U/L increase (HR/CI: 0.997/0.996-0.999, P = 0.003), and γ-glutamyl transferase level per U/L increase (HR/CI: 1.002/1.001-1.003, P < 0.001). No significant difference in all-cause mortality was observed between the ETV and TDF groups (log-rank test, P = 0.69). After propensity score matching, no significant differences in all-cause, liver-related, or non-liver-related mortality were observed between the two groups. CONCLUSIONS: Long-term outcomes of all-cause mortality and liver-related and non-liver-related mortality did not differ between patients treated with ETV and those receiving TDF.

BACKGROUND: Immune checkpoint inhibitors (ICIs) are effective for advanced hepatocellular carcinoma (HCC). However, there are few reports on the correlation between the clinical efficacy of ICIs and the development of immune-related adverse events (irAEs) in patients with HCC. The aim of this study was to investigate the association between irAE development and survival in patients with HCC treated with atezolizumab plus bevacizumab. PATIENTS AND METHODS: We enrolled 150 patients with advanced HCC treated with atezolizumab plus bevacizumab between October 2020 and October 2021 at 5 territorial institutions. We compared the efficacy of atezolizumab plus bevacizumab between patients who experienced irAEs (irAE group) and those who did not (non-irAE group). RESULTS: Thirty-two patients (21.3%) developed irAEs of any grade. Grade 3/4 irAEs were observed in 9 patients (6.0%). The median progression-free survivals (PFS) in the irAE and non-irAE groups were 273 and 189 days, respectively (P = .055). The median overall survivals (OS) in the irAE and non-irAE groups were not reached and 458 days, respectively (P = .036). Grade 1/2 irAEs significantly prolonged PFS (P = .014) and OS (P = .003). Grade 1/2 irAEs were significantly associated with PFS (hazard ratio [HR], 0.339; 95% confidence interval [CI], 0.166-0.691; P = .003) and OS (HR, 0.086; 95% CI, 0.012-0.641; P = .017) on multivariate analysis. CONCLUSION: The development of irAEs was associated with increased survival in a real-world population of patients with advanced HCC treated with atezolizumab plus bevacizumab. Grade 1/2 irAEs were strongly correlated with PFS and OS.

AIM: The association between thrombolytic therapy and the outcome in patients with portal vein thrombosis (PVT) remains controversial. This study aimed to evaluate the outcome in patients with PVT who received antithrombin III-based therapy. METHODS: This study was a retrospective, multicenter study to investigate the liver-related events and the survival rates in 240 patients with PVT who received the therapy. RESULTS: The patients comprised 151 men and 89 women, with a median age of 69 years. The rate of favorable response, defined as maximum area of PVT changed to ≤75%, was 67.5% (162/240). The cumulative rates of liver-related events at 1, 2, and 3 years were 38.2%, 53.9%, and 68.5%, respectively. The multivariate analysis showed that viable hepatocellular carcinoma, absence of maintenance therapy, non-responder, and PVT progression were significantly associated with liver-related events. The PVT progression was observed in 23.3% (56/240). The multivariate analysis identified older age, absence of maintenance therapy, and non-responder as independent factors associated with PVT progression. The multivariate analysis revealed that younger age, no hepatocellular carcinoma, presence of maintenance therapy, and lower Model for End-stage Liver Disease-Sodium score significantly contributed to 3-year survival. Of the 240 patients, 13 (8.9%) prematurely discontinued treatment due to any adverse events. CONCLUSIONS: This study suggests that maintenance therapy, favorable response, and absence of PVT progression may suppress or control liver-related events in antithrombin III-based therapy for patients with PVT. Specifically, maintenance therapy could suppress not only liver-related events, but also PVT progression and improve the prognosis.
RESUMEN
BACKGROUND AND AIMS: Real-world data for treatment effectiveness and renal outcomes in chronic hepatitis B (CHB) patients who were switched to the new and safer prodrug tenofovir alafenamide (TAF) from tenofovir disoproxil fumarate (TDF) are limited. Therefore, we aimed to evaluate treatment and renal outcomes of this population. APPROACH AND RESULTS: We analyzed 834 patients with CHB previously treated with TDF for ≥12 months who were switched to TAF in routine practice at 13 US and Asian centers for changes in viral (HBV DNA < 20 IU/mL), biochemical (alanine aminotransferase [ALT] < 35/25 U/L for male/female), and complete (viral+biochemical) responses, as well as estimated glomerular filtration rate (eGFR; milliliters per minute per 1.73 square meters) up to 96 weeks after switch. Viral suppression (P < 0.001) and ALT normalization (P = 0.003) rates increased significantly after switch, with a trend for increasing complete response (Ptrend = 0.004), while the eGFR trend (Ptrend > 0.44) or mean eGFR (P > 0.83, adjusted for age, sex, baseline eGFR, and diabetes, hypertension, or cirrhosis by generalized linear modeling) remained stable. However, among those with baseline eGFR < 90 (chronic kidney disease [CKD] stage ≥2), mean eGFR decreased significantly while on TDF (P = 0.029) but not after TAF switch (P = 0.90). By week 96, 21% (55/267) of patients with CKD stage 2 at switch improved to stage 1 and 35% (30/85) of CKD stage 3-5 patients improved to stage 2 and 1.2% (1/85) to stage 1. CONCLUSIONS: Overall, we observed continued improvement in virologic response, ALT normalization, and no significant changes in eGFR following switch to TAF from TDF.

BACKGROUND: Lenvatinib is appropriate for reducing the production of nitric oxide (NO) and facilitating as block angiogenesis. However, to our knowledge, there are no data that support the correlation between NO and clinical response in patients who received lenvatinib therapy for HCC. Therefore, we investigated the correlation between the change rate of NO levels and clinical responses including adverse events (AEs) after lenvatinib therapy for unresectable hepatocellular carcinoma (HCC). METHODS: This study was conducted using previously collected data from another study. We enrolled 70 patients who received lenvatinib for advanced or unresectable HCC. NO was measured by converting nitrate (NO3-) to nitrite (NO2-) with nitrate reductase, followed by quantitation of NO2- based on Griess reagent. To determine whether lenvatinib influences NO in unresectable HCC, we evaluated the influence of the change rate of NO from baseline after administration of lenvatinib on maximal therapeutic response and SAE. RESULTS: After lenvatinib administration, a change rate in the NO from 0.27 to 4.16 was observed. There was no difference between the clinical response to lenvatinib and the change rate of NO (p = 0.632). However, the change rate of NO was significantly lower in patients with AEs than in those without AEs (p = 0.030). When a reduction in NO rate of < 0.8 was defined as a clinically significant reduction of NO (CSRN), the CSRN group had significantly worse progression-free survival (PFS) and overall survival (OS) than the non-CSRN group (p = 0.029 and p = 0.005, respectively). CONCLUSION: Decreased NO levels were associated with the occurrence of AEs and worse prognosis after lenvatinib administration. Change rate in serum NO can be used as predictive markers in patients receiving lenvatinib therapy for HCC.

BACKGROUND: Transarterial chemoembolization (TACE) is the standard treatment for intermediate stage hepatocellular carcinoma (HCC) (Barcelona Clinic Liver Cancer [BCLC] B). However, it often leads to a poor prognosis and decreased hepatic function especially in patients with BCLC substage B2. Lenvatinib (LEN) was demonstrated to be efficacious in these patients in the REFLECT phase 3 trial. We therefore aimed to evaluate the efficacy and safety of LEN as a first-line treatment for the patients with HCC at BCLC substage B2. METHODS: This prospective observational study used LEN in TACE-naïve patients with HCC at BCLC substage B2 and preserved hepatic function. The primary endpoint was overall survival. A one-year survival rate threshold of 60% and an expected survival rate of 78%, based on previous reports of TACE, was assumed for setting the sample size. With a one-sided α-type error of 5% and 70% detection power, 25 patients were required over a 2-year enrollment period and 10-month follow-up period. RESULTS: Thirty-one patients were enrolled in this study from June 2018 to June 2020. The 1-year survival rate was 71.0% (90% confidence interval, 68.4-73.6%). Median overall and progression-free survival periods were 17.0 and 10.4 months, and the objective response rates according to Response Evaluation Criteria in Solid Tumor (RECIST) version 1.1 and modified RECIST criteria were 22.6% and 70.0%, respectively. Common adverse events (AEs) were fatigue (68%), hypertension (65%), anorexia (61%), palmar-plantar erythrodysesthesia (39%), and thrombocytopenia (32%) of any grade; aspartate aminotransferase increased (23%), alanine aminotransferase increased (16%), and grade ≥ 3 proteinuria (13%). Treatment interruption and dose reduction were required in 61% and 81% of patients, respectively. LEN was discontinued in 29 patients due to disease progression (n = 17), AEs (n = 9), conversion to curative treatments (n = 2), and sudden death (n = 1), whereas post-LEN treatments were administered in 18 patients, including systemic chemotherapy (n = 11), TACE (n = 6), transarterial infusion (n = 1) and clinical trial (n = 1). CONCLUSIONS: The results suggest that LEN provides treatment benefits as an initial therapeutic in patients with BCLC substage B2 HCC with a safety profile comparable to that previously reported.

PURPOSE: To assess the impact of clinical factors on the safety and efficacy of atezolizumab plus bevacizumab (ATZ + BV) treatment in patients with unresectable hepatocellular carcinoma (u-HCC). METHOD: Ninety-four u-HCC patients who were treated with ATZ + BV at multiple centers were enrolled. We defined Child-Pugh (CP)-A patients who received ATZ + BV treatment as a first line therapy as the 'meets the broad sense of the IMbrave150 criteria' group (B-IMbrave150-in, n = 46), and patients who received ATZ + BV treatment as a later line therapy or CP-B patients (regardless of whether ATZ + BV was a first line or later line therapy) as the B-IMbrave150-out group (n = 48). Patients were retrospectively analyzed for adverse events (AEs) and treatment outcomes according to their clinical characteristics, including neutrophil lymphocyte ratio (NLR) at baseline. RESULTS: The overall incidence of AEs was 87.2% (82/94 patients). The frequency of interruption of ATZ + BV treatment due to fatigue was higher in CP-B than CP-A patients (p = 0.030). Objective response (OR) rates of the B-IMbrave150-in group (28.3%, 39.1%) were significantly higher than those of the B-IMbrave150-out group (8.3%, 18.8%; p = 0.0157, 0.0401) using Response Evaluation Criteria in Solid Tumors (RECIST) and modified RECIST, respectively. In multivariate analysis, NLR (hazard ratio (HR), 4.591; p = 0.0160) and B-IMbrave150 criteria (HR, 4.108; p = 0.0261) were independent factors associated with the OR of ATZ + BV treatment using RECIST. CONCLUSION: In real-world practice, ATZ + BV treatment might offer significant benefits in patients who meet B-IMbrave150 criteria or have low NLR.
RESUMEN
AIM: Direct-acting antivirals (DAAs) are currently available even for patients with decompensated cirrhosis. Reportedly, hepatic functional reserve improved in the short term after achievement of sustained virologic response (SVR). We aimed to clarify the outcomes after achievement of SVR in patients with decompensated cirrhosis who were treated by DAAs in real-world clinical practice. METHODS: A prospective, multicenter study of 12-week sofosbuvir/velpatasvir was conducted in 86 patients with decompensated cirrhosis, who were evaluated for 48 weeks post-treatment. RESULTS: The cohort included 8 patients with Child-Pugh class A, 56 with B, and 22 with C. The proportion of Child-Pugh class A patients increased from 9.1% at baseline to 44.1% at 48 weeks post-treatment, while that of class B and C patients decreased from 66.2% to 35.1% and from 24.7% to 14.3%, respectively. Among the patients with Child-Pugh class B and C, univariate analysis identified low total bilirubin, Child-Pugh score, Child-Pugh class B, ALBI score, and high serum albumin as factors associated with improvement to Child-Pugh class A. The optimal cut-off value of the factors for predicting improvement to Child-Pugh class A were 1.4 mg/dl for total bilirubin, 2.9 g/dl for serum albumin, 8 points for Child-Pugh score, and -1.88 for ALBI score. CONCLUSION: Achievement of SVR with sofosbuvir/velpatasvir improved the liver functional reserve at 12 weeks post-treatment and maintained the stable effects until 48 weeks post-treatment in patients with decompensated cirrhosis. Specifically, the patients with less advanced conditions had the likelihood of improving to Child-Pugh class A at 48 weeks post-treatment.
RESUMEN
INTRODUCTION: With the increase in the number of patients with sustained virologic response (SVR) in whom hepatitis C virus (HCV) was eradicated by the anti-HCV therapy, there are now many individuals in whom serum HCV RNA is absent despite positive serum HCV antibodies. However, in general clinical practice, HCV infection remains usually screened by measurement of serum HCV antibodies and patients with SVR can be misunderstood regarding HCV infection status. METHODS: In the multicenter study, we conducted interviews with administered questionnaires to SVR individuals who had regular hospital visits after SVR. The prevalence of experiencing an incorrect diagnosis of HCV infection after SVR was assessed. Individuals who experienced this misunderstanding were further asked where they experienced it and how it made them feel. RESULTS: In a survey of 2,246 SVR individuals, 197 individuals (8.8%) were misunderstood as having persistent HCV infection by medical doctors due to positive HCV antibody, despite the absence of HCV viremia. These misunderstandings occurred most prevalently at a private clinic (55.3%). More than half (53.3%) of these individuals felt anxious about their HCV infection with becoming unsure about their HCV eradication status. CONCLUSIONS: Misunderstanding HCV status is commonly occurred in SVR individuals. Specialists in hepatology and infectious diseases should broadly emphasize the fact that most patients with HCV antibodies are now HCV-free because of the use of anti-HCV therapy.

Nonalcoholic fatty liver disease (NAFLD) is an increasingly common condition, affecting up to 25% of the population worldwide. NAFLD has been linked to several conditions, including hepatic inflammation, fibrosis, and hepatocellular carcinoma (HCC), however the role of NAFLD in cholangitis and the development of cholangiocellular carcinoma (CCC) remains poorly understood. This study investigated whether a high-fat diet (HFD) promotes cholangitis and the development of CCC in mice. We used liver-specific E-cadherin gene (CDH1) knockout mice, CDH1∆Liv , which develop spontaneous inflammation in the portal areas along with periductal onion skin-like fibrosis, similar to that of primary sclerosing cholangitis (PSC). An HFD or normal diet (ND) was fed to CDH1∆Liv mice for 7 mo. In addition, CDH1∆Liv mice were crossed with LSL-KrasG12D mice, fed an HFD, and assessed in terms of liver tumor development. The extent of cholangitis and number of bile ductules significantly increased in mice fed an HFD compared with ND-administered CDH1∆Liv mice. The numbers of Sox9 and CD44-positive stem cell-like cells were significantly increased in HFD mice. LSL-KrasG12D /CDH1∆Liv HFD mice exhibited increased aggressiveness along with the development of numerous HCC and CCC, whereas LSL-KrasG12D /CDH1∆Liv ND mice showed several macroscopic tumors with both HCC and CCC components. In conclusion, NAFLD exacerbates cholangitis and promotes the development of both HCC and CCC in mice.

INTRODUCTION: Entecavir (ETV) and tenofovir alafenamide (TAF) are both first-line hepatitis B virus (HBV) therapies, but ETV-to-TAF switch outcome data are limited. We aimed to assess outcomes up to 96 weeks after ETV-to-TAF switch. METHODS: ETV-treated (≥12 months) chronic hepatitis B patients switched to TAF in routine practice at 15 centers (United States, Korea, Japan, and Taiwan) were included. Primary outcome was complete viral suppression (CVS) rate (HBV DNA <20 IU/mL). RESULTS: We analyzed 425 eligible patients (mean age 60.7 ± 13.2 years, 60% men, 90.8% Asian, 20.7% with diabetes, 27% with hypertension, 14.8% with cirrhosis, 8.3% with hepatocellular carcinoma, and mean ETV duration before switch 6.16 ± 3.17 years). The mean baseline estimated glomerular filtration rate (eGFR) was 89 ± 19 (chronic kidney disease [CKD] stages: 55.6% stage 1, 35.7% stage 2, and 8.8% stages 3-5). CVS rate increased from 91.90% at switch (from 90.46% 24 weeks before switch) to 95.57% and 97.21% at 48 and 96 weeks after (P = 0.03 and 0.02, respectively). Over the 96 weeks after switch, mean HBV DNA (P < 0.001) but not alanine aminotransferase or CKD stage decreased. Between switch and 96-week follow-up, 11% (26/235) of CKD stage 1 patients migrated to stage 2 and 8% (12/151) of stage 2 patients to stages 3-5, whereas 18% (27/151) from stage 2 to 1, and 19% (7/37) from stages 3-5 to 2. On multivariable generalized estimated equation analysis adjusted for age, sex, hypertension, diabetes, and cirrhosis, baseline eGFR, age (P < 0.001), and CKD stages 2 and 3-5 (vs 1) (both P < 0.001) were associated with lower follow-up eGFR. DISCUSSION: After an average of 6 years on ETV, CVS increased from 91.9% at TAF switch to 97.2% at 96 weeks later.

BACKGROUND: In clinical practice, many hepatocellular carcinoma (HCC) patients in Barcelona Clinical Liver Cancer (BCLC) stage A4-B1 cannot receive the curative treatments of liver transplantation, resection, and radiofrequency ablation (RFA), which are the recommended options according to liver cancer guidelines. Our aim is to study the feasibility of RFA and stereotactic body radiotherapy (SBRT) as a curative treatment for different multifocal HCCs in BCLC stage A4-B1 patients. METHODS: From September 2014 to August 2019, 39 multifocal HCC lesions (median diameter: 16.6 mm) from 15 patients (median age: 73 years) were retrospectively selected. Among them, 23 were treated by RFA and the other 16 by SBRT because of predictable insufficiency and/or risk related to RFA performance. The indicators for evaluating this novel therapy were the tumor response, prognosis (recurrence and survival), and adverse effects (deterioration of laboratory test values and severe complications). RESULTS: The median follow-up duration was 31.3 months (range: 15.1-71.9 months). The total patients with a one-year complete response, stable disease, or disease progression were 11, 1, and 3, respectively. In total, 8 and 2 patients had confronted intrahepatic or local recurrence, respectively. The one-year progression-free survival rate and local control rate were 80% (12/15 patients) and 97.4% (38/39 lesions), respectively. The median time to progression was 20.1 (2.8-45.1) months. The one- and two-year survival rates were 100 and 88.9%, respectively. In up to five months' observation, no patient showed severe complications. Seven, four, and two patients had slight changes in their white blood cells, platelet count, or albumin-bilirubin grade, respectively. CONCLUSIONS: For patients with BCLC stage A4-B1, RFA and SBRT treatment for different multifocal HCCs may be a potential option because of the favorable prognosis and safety. However, before its application in clinical practice, prospective, controlled, large-scale studies are needed to further confirm our conclusions.

AIMS: To assess the safety, efficacy, and prognostic impact of clinical factors associated with lenvatinib treatment in highly advanced hepatocellular carcinoma (HCC) with tumor thrombus in the main portal vein trunk (VP4) or tumor with more than 50% liver occupation (tm50%LO). METHODS: A total of 61 highly advanced HCC patients (41 patients with tm50%LO and 20 patients with VP4) who were treated with lenvatinib at multicenter were enrolled and retrospectively analyzed for treatment outcomes according to their clinical status, including tumor morphology. RESULTS: The most frequent grade ≥3 adverse event in tm50%LO HCC was elevated aspartate aminotransferase (17.1%). Objective response rates were 37.5% and 0% in tm50%LO HCC patients with Child-Pugh grade (CP)-A and CP-B, respectively, and 26.7% and 0% in VP4 HCC patients with CP-A and CP-B, respectively. Estimated median progression-free survival and overall survival were 132 days and 229 days, and 101 days and 201 days in patients with tm50%LO and VP4, respectively. In multivariate analysis, modified albumin-bilirubin grade (hazard ratio 0.372, 95% CI 0.157-0.887; p = 0.0241) and tumor morphology (hazard ratio 0.322, 95% CI 0.116-0.889; p = 0.0287) were independently associated with progression-free survival in patients with tm50%LO HCC. In VP4 HCC, median progression-free survival was worse in CP-B (57 days) than in CP-A patients (137 days, p = 0.0462). CONCLUSIONS: Lenvatinib treatment offers a benefit in highly advanced HCC (tm50%LO or VP4) patients with good liver function or nodular-type tumor. The various characteristics identified in this study might be useful as indicators of lenvatinib treatment in highly advanced HCC with tm50%LO or VP4, which are considered very refractory cancers.
RESUMEN
AIM: Recently, a new method has been developed to diagnose hepatic steatosis with attenuation coefficients based on the ultrasound-guided attenuation parameter (UGAP). We investigated whether fibrosis identified by hepatic stiffness measurements based on magnetic resonance elastography (MRE) affects attenuation coefficient measurement using UGAP for the evaluation of hepatic steatosis. METHODS: A total of 608 patients with chronic liver disease were analyzed. Correlations between magnetic resonance imaging-determined proton density fat fraction (PDFF) or MRE value and attenuation coefficients were evaluated. In addition, the interaction between hepatic fibrosis and the attenuation coefficient was analyzed. RESULTS: The correlation coefficient (r) between PDFF values and attenuation coefficient values was 0.724, indicating a strong relationship. Conversely, the r between MRE values and attenuation coefficient values was -0.187, indicating almost no relationship. In the multiple regression assessment of the effect of PDFF and MRE on the attenuation coefficient based on UGAP, the P-values for PDFF, MRE, and PDFF × MRE were < 0.001, 0.277, and 0.903, respectively. In patients with non-alcoholic fatty liver disease (n = 169), the r between PDFF values and attenuation coefficient values was 0.695, indicating a moderate relationship. Conversely, the r between MRE values and attenuation coefficient values was -0.068, indicating almost no relationship. In the multiple regression assessment of the effect of PDFF and MRE on the attenuation coefficient based on UGAP, the P-values for PDFF, MRE, and PDFF × MRE were <0.001, 0.948, and 0.706, respectively. CONCLUSION: UGAP-determined attenuation coefficient was weakly affected by liver stiffness, an indicator of hepatic fibrosis.
