Abstract In the current era of immune therapy, lenvatinib (LEN) continues to be vital for treating unresectable hepatocellular carcinoma (uHCC) patients. This study investigates the importance of nutritional status in the prognosis of uHCC patients receiving LEN and evaluates a new prognostic scoring system that combines the geriatric nutritional risk index (GNRI) and systemic inflammatory response. From 2018 to 2022, 484 uHCC patients treated with LEN (384 males, median age 73). Prognostic value was compared between GNRI and C-reactive protein (CRP) scoring (GNRI-C score), GNRI, and neo-Glasgow prognostic score (neo-GPS). Evaluation was based on the Akaike information criterion (AIC) and concordance index(c-index). Median progression-free survival (mPFS) was 9.3/6.8/4.6 months for GNRI no-risk/low-risk/moderate-to-major risk (p

Abstract Baveno VII criteria (B7C) and Baveno VI criteria (B6C) have been widely used to estimate the risk of hepatic decompensation. However, the impact of age on these criteria warrants further investigation. The international, multicenter cohort study included 1138 patients with compensated cirrhosis (median follow‐up of 40.6 months), aiming to evaluate the value of age in predicting hepatic decompensation. We identified age as an independent predictor of hepatic decompensation, with 60 years determined as the optimal cut‐off value. The occurrence of decompensation was 18.7% and 6.7% in the older (age ≥60 years) and younger (age 0.05). In conclusion, our study demonstrated that integrating age into the Baveno criteria could enhance the assessment of hepatic decompensation. Age should be considered before discharging patients with compensated cirrhosis from the surveillance of hepatic decompensation.

Background Poor lifestyle habits may worsen nonalcoholic fatty liver disease (NAFLD), with progression to nonalcoholic steatohepatitis (NASH) and cirrhosis. This study investigated the association between glycemic control status and hepatic histological findings to elucidate the effect of glycemic control on NAFLD. Methods This observational study included 331 patients diagnosed with NAFLD by liver biopsy. Effects of the glycemic control status on histological findings of NAFLD were evaluated by comparing the following four glycemic status groups defined by the glycosylated hemoglobin (HbA1c) level at the time of NAFLD diagnosis: ≤5.4%, 5.5%–6.4%, 6.5%–7.4%, and ≥7.5%. Results Compared with the lowest HbA1c group (≤5.4%), the higher HbA1c groups (5.5%–6.4%, 6.5%–7.4%, and ≥7.5%) were associated with advanced liver fibrosis and high NAFLD activity score (NAS). On multivariate analysis, an HbA1c level of 6.5%– 7.4% group was significantly associated with advanced fibrosis compared with the lowest HbA1c group after adjusting for age, sex, hemoglobin, alanine aminotransferase, and creatinine levels. When further controlling for body mass index and uric acid, total cholesterol, and triglyceride levels, the higher HbA1c groups were significantly associated with advanced fibrosis compared with the lowest HbA1c group. On the other hand, compared with the lowest HbA1c group, the higher HbA1c groups were also associated with a high NAS in both multivariate analyses. Conclusion Glycemic control is associated with NAFLD exacerbation, with even a mild deterioration in glycemic control, especially a HbA1c level of 6.5%–7.4%, contributing to NAFLD progression.

Abstract Aim This retrospective study compared the impact of atezolizumab plus bevacizumab (Atez/Bev) and lenvatinib (LEN) on the liver function in patients with hepatocellular carcinoma. Methods We included 526 patients who received Atez/Bev and 731 who received LEN March 2018 and July 2022 in this study. We conducted a 1:1 propensity‐score‐matched analysis and identified 324 patients in each group for inclusion in the present analysis. Nonlinear mixed‐effects regression models were employed, allowing for the evaluation and inclusion of cases where treatment was interrupted due to disease progression, adverse events, or loss to follow‐up. These models were used to compare the ALBI score between the Atez/Bev and LEN groups. Results Following propensity score matching, the mean ALBI scores in the Atez/Bev and LEN groups were −2.41 ± 0.40 and −2.44 ± 0.42 at baseline, and −2.17 ± 0.56 and −2.19 ± 0.58 at 12 weeks, respectively. Although the ALBI score significantly worsened during treatment in both groups (p

Abstract Aims The aim of the present study was to elucidate detailed parameters for prediction of prognosis for patients with unresectable hepatocellular carcinoma (uHCC) receiving atezolizumab plus bevacizumab (Atez/Bev) treatment. Methods A total of 719 patients (males 577, median age 74 years) treated with Atez/Bev between September 2020 and January 2023 were enrolled. Factors related to overall survival (OS) were extracted and a prognostic scoring system based on hazard ratio (HR) was created. OS and progression‐free survival (PFS) were retrospectively examined, and the prognostic ability of the newly developed system was compared to CRAFITY score using concordance index (c‐index) and Akaike information criterion (AIC) results. Results Cox‐hazards multivariate analysis showed BCLC classification C/D (HR 1.4; 1 point), AFP ≥100 ng/mL (HR 1.4; 1 point), mALBI 2a (HR 1.7; 1 point), mALBI 2b/3 (HR 2.8; 2 points), and DCP ≥100 mAU/mL (HR 1.6; 1 point) as significant factors. The assigned points were added and used to develop the IMmunotherapy with AFP, BCLC staging, mALBI, and DCP evaluation (IMABALI‐De) scoring system. For IMABALI‐De scores of 0, 1, 2, 3, 4, and 5, OS was not applicable (NA), NA, 26.11, 18.79, 14.07, and 8.32 months, respectively (p

Introduction The impact of etiology on response to immunotherapy in advanced hepatocellular carcinoma (HCC) is being debated, with contrasting findings between early and recent post-hoc analyses of IMbrave-150 and metanalyses of clinical trials of PD-1/PD-L1 blockers. As a results, it is not clear whether the first-line systemic treatment atezolizumab plus bevacizumab is equally effective in viral and non-viral patients. Methods We retrospectively analyzed 885 HCC patients treated with first-line A + B from multiple centers from Eastern and Western countries, 53.9% having viral and 46.1% non-viral etiology. Baseline clinical and laboratory characteristics were analyzed with uni- and multi-variate models to explore potential differences on overall survival (OS), time to progression (TTP), disease control rates based on etiology and to identify putative prognostic factors in etiology subgroups. Treatment toxicities and access to second-line treatments and outcomes were also reported and compared between etiologies. Results Overall, no statistically significant differences were found in OS (mOS: viral 15.9 months; non-viral 16.3 months), TTP (mTTP: viral 8.3 months; non-viral 7.2 months), and disease control rates (DCR: viral 78.1%; non-viral 80.8%) based on etiology. Prognostic factors of survival and progression were mainly shared between viral and non-viral etiologies, including alpha-fetoprotein, aspartate transaminase, neutrophil-to-lymphocyte ratio (NLR) and ALBI score. Exploratory analyses highlighted a possible stronger association of immunological factors, i.e. NLR and eosinophil count, to treatment outcomes in viral patients. The toxicity profile, the access to and type of second-line treatments and their outcome in terms of OS almost overlap in the two etiology subgroups. Conclusion Atezolizumab plus bevacizumab efficacy does not vary according to underlying etiology of HCC in a multicenter, real-world population, matching recent post-hoc findings from the IMbrave-150 trial. Preliminary analyses suggest that some prognostic factors differ between viral and non-viral patients, potentially due to biological and immunological differences. Prospective and comparative trials stratifying by etiology are warranted to validate these findings and guide clinical practice.

Abstract Aim To investigate the possible correlation between the development of adverse events (AEs) and prognosis in patients with unresectable hepatocellular carcinoma (HCC) treated with atezolizumab plus bevacizumab (Atez/Bev). Methods A total of 286 patients with unresectable HCC treated with Atez/Bev as first‐line systematic therapy were included. Results Regarding treatment‐related AEs, decreased appetite of any grade, proteinuria of any grade, and fatigue of any grade were found with a frequency of ≥20%. Multivariate analysis adjusted for immune‐related liver injury, immune‐related endocrine dysfunction, proteinuria, fatigue, decreased appetite, hypertension, sex, age, Eastern Cooperative Oncology Group performance status, HCC etiology, HCC stage, Child–Pugh score, and α‐fetoprotein showed that hypertension of any grade (hazard ratio [HR], 0.527; 95% confidence interval [CI], 0.326–0.854; p = 0.009) and α‐fetoprotein ≥100 ng/ml (HR, 1.642; 95% CI, 1.111–2.427; p = 0.013) were independently associated with progression‐free survival. Multivariate analysis adjusted for the same AEs showed that fatigue (HR, 2.354; 95% CI, 1.299–4.510; p = 0.010) was independently associated with overall survival. Median progression‐free survival was 6.5 months (95% CI, 5.2–8.1) in patients without hypertension of any grade and 12.6 months (95% CI, 6.7–not available) in patients with hypertension of any grade (p = 0.035). The overall survival was significantly shorter in patients in whom treatment‐related fatigue of any grade was observed (p

Abstract Aim This study compared the efficacy and safety of atezolizumab and bevacizumab (Atez/Bev) in patients with viral and non‐viral infection in clinical settings. Methods We conducted the retrospective cohort study of 323 BCLC stage B or C hepatocellular carcinoma (HCC) patients with Child‐Pugh class A, and a performance status of 0 or 1 who started Atez/Bev from September 2020 to December 2021 at 22 institutions in Japan. Patients with viral infection was defined as those who were either serum anti‐HCV‐ Ab or HBs‐Ag‐positive, while patients with non‐viral infection was defined as those who were both serum anti‐HCV Ab‐ and HBs‐Ag‐negative. We constructed a propensity‐score‐matched cohort to minimize the risk of observable potential confounders. Results Propensity score matching produced 126 matched pairs for patients with viral versus non‐viral infection. After matching, the significant differences in baseline demographic features did not exist between the two groups. The objective response rate was 20.6% and 24.6% in viral‐ and non‐viral‐related HCC patients, respectively, without a significant difference (p = 0.55). The disease control rate was not also significantly different (68.3% vs 69.0%, p = 1.00). The median progression‐free survival was 7.0 months (95% confidence interval [CI] 6.0–9.6) and 6.2 months (95% CI 5.1–7.8) in patients with viral and non‐viral infection, and the 12‐month survival rates were 65.5% (95% CI 50.8–76.8) and 71.7% (95% CI 57.3–81.9) in those with viral and non‐viral infection, respectively, which were not significantly different (p = 0.33, p = 0.38). No significant difference in treatment‐related adverse events was found between the two groups. Conclusions Our etiology‐based study demonstrated that Atez/Bev showed good efficacy and safety for HCC patient with non‐viral infection as well as those with viral infection.

Abstract Aim Recently, the neo‐Glasgow prognostic score (GPS), a composite biomarker determined by the C‐reactive protein level and albumin–bilirubin grade, was developed to predict outcomes in hepatocellular carcinoma (HCC) patients who undergo hepatic resection. The present research investigated whether the neo‐GPS could predict prognosis in HCC patients treated with atezolizumab plus bevacizumab (Atez/Bev). Methods A total of 421 patients with HCC who were treated with Atez/Bev were investigated. Results Multivariate Cox hazards analysis showed that a GPS of 1 (hazard ratio (HR), 1.711; 95% confidence interval (CI), 1.106–2.646) and a GPS of 2 (HR, 4.643; 95% CI, 2.778–7.762) were independently associated with overall survival. Conversely, multivariate Cox hazards analysis showed that a neo‐GPS of 1 (HR, 3.038; 95% CI, 1.715–5.383) and a neo‐GPS of 2 (HR, 5.312; 95% CI, 2.853–9.890) were also independently associated with overall survival in this cohort. Additionally, cumulative overall survival rates differed significantly by GPS and neo‐GPS (p

Abstract Aim This study investigated whether or not the hepatocellular carcinoma modified Gustave Roussy Immune Score (HCC‐GRIm‐Score) serves as a prognostic indicator for HCC patients treated with atezolizumab and bevacizumab (Atez/Bev). Methods A total of 405 HCC patients who received Atez/Bev from September 2020 to January 2022 at 22 different institutions were included in this retrospective study. The HCC‐GRIm score was based on the combination of the albumin level (

Abstract Background/Aim A comparison of therapeutic efficacy between atezolizumab plus bevacizumab (Atez/Bev) and lenvatinib treatment given as first‐line therapy for unresectable hepatocellular carcinoma (u‐HCC) in regard to progression‐free survival (PFS) overall survival (OS) has not been reported. We aimed to elucidate which of those given as initial treatment for u‐HCC has greater prognostic impact on PFS and OS of affected patients, retrospectively. Materials/Methods From 2020 to January 2022, 251 u‐HCC (Child–Pugh A, ECOG PS 0/1, BCLC‐B/C) treated were enrolled (Atez/Bev‐group, n = 194; lenvatinib‐group, n = 57). PFS and OS were analyzed following adjustment based on inverse probability weighting (IPW). Results There was a greater number of patients with macro‐vascular invasion in Atez/Bev‐group (22.7% vs. 8.8%, p = 0.022). In lenvatinib‐group, the frequencies of appetite loss (38.6% vs. 19.6%, p = 0.002), hypothyroidism (21.1% vs. 6.7%, p = 0.004), hand foot skin reaction (19.3% vs. 1.0%, p

Abstract Aim The safety and efficacy of atezolizumab plus bevacizumab (Atez/Bev) in elderly patients with unresectable hepatocellular carcinoma (HCC) have not been sufficiently investigated. Methods A total of 317 patients with HCC treated with Atez/Bev were studied. We compared the survival and frequency of adverse events in elderly versus non‐elderly patients with HCC who were treated with Atez/Bev using an analysis of inverse probability weighting (IPW). Results Univariate analysis adjusted with IPW showed that being elderly is not associated with worse overall or progression‐free survival (hazard ratio [HR], 1.239; 95% confidence interval [CI], 0.640–2.399; p = 0.526 and HR, 1.256; 95% CI, 0.871–1.811; p = 0.223, respectively). Regarding treatment‐related adverse events, any grade of fatigue, proteinuria, decreased appetite, hypertension, and liver injury occurred in ≥10% of patients. There were no significant differences in treatment‐related adverse events between the elderly and non‐elderly groups. In a subgroup analysis of elderly patients aged 75–79, 80–84, or ≥ 85 years, there were no significant differences in cumulative overall or progression‐free survival among these age groups (p = 0.960 and 0.566, respectively). In addition, there were no significant differences in treatment‐related adverse events among these three age groups, except for proteinuria of any grade. In a subgroup analysis of patients treated with Atez/Bev as first‐line systemic therapy, there were no significant differences in cumulative overall or progression‐free survival between the elderly and non‐elderly groups (p = 0.728 and 0.805, respectively). Conclusions Atez/Bev can be used efficaciously and safely in spite of age in patients with unresectable HCC.

Abstract Aims/Introduction To investigate whether the Fibrosis‐4 index can help stratify the risk of diabetes mellitus in patients with fatty liver disease. Materials and Methods Based on fatty liver disease and Fibrosis‐4 index (cut‐off value 1.3), we retrospectively divided 9,449 individuals, who underwent at least two annual health checkups, into four groups stratified by sex: normal; high Fibrosis‐4 index without fatty liver disease; low Fibrosis‐4 index with fatty liver disease; and high Fibrosis‐4 index with fatty liver disease. Results Onset rates for diabetes mellitus in the normal, high Fibrosis‐4 index without fatty liver disease, low Fibrosis‐4 index with fatty liver disease and high Fibrosis‐4 index with fatty liver disease groups were 1.6%, 4.3%, 6.8% and 10.2%, respectively, in men, and 0.6%, 0.9%, 5.3% and 7.0%, respectively, in women. Compared with the normal group, the high Fibrosis‐4 index without fatty liver disease, low Fibrosis‐4 index with fatty liver disease and high Fibrosis‐4 index with fatty liver disease groups were at a significant risk for diabetes mellitus onset in both male and female participants. Furthermore, in both sexes, high Fibrosis‐4 index with fatty liver disease remained a significant risk factor on multivariate analysis (high fibrosis‐4 index with fatty liver disease group: adjusted hazard ratio 4.03, 95% confidence interval 2.19–7.42 [men] and adjusted hazard ratio 6.40, 95% confidence interval 1.77–23.14 [women]). Conclusions Individuals with fatty liver disease and high Fibrosis‐4 index had a higher risk of diabetes mellitus onset. Therefore, Fibrosis‐4 index can help stratify the risk of diabetes mellitus in patients with fatty liver disease and identify patients requiring intervention.

Abstract Introduction Nonalcoholic fatty liver disease (NAFLD) is diagnosed after excluding other liver diseases. The pathogenesis of NAFLD when complicated by other liver diseases has not been established completely. Metabolic dysfunction‐associated fatty liver disease (MAFLD) involves more metabolic factors than NAFLD, regardless of complications with other diseases. This study aimed to clarify the effects of fatty liver occurring with metabolic disorders, such as MAFLD without diabetes mellitus (DM), on the development of DM. Materials and Methods We retrospectively assessed 9,459 participants who underwent two or more annual health check‐ups. The participants were divided into the MAFLD group (fatty liver disease with overweight/obesity or non‐overweight/obesity complicated by metabolic disorders), simple fatty liver group (fatty liver disease other than MAFLD group), metabolic disorder group (metabolic disorder without fatty liver disease), and normal group (all other participants). Results The DM onset rates in the normal, simple fatty liver, metabolic disorder, and MAFLD groups were 0.51, 1.85, 2.52, and 7.36%, respectively. In the multivariate analysis, the MAFLD group showed a significantly higher risk of DM onset compared with other three groups (P

Abstract We investigated the impact of C-reactive protein to albumin ratio (CAR) on predicting outcomes in 522 patients with unresectable hepatocellular carcinoma (HCC) treated with lenvatinib. We determined the optimal CAR cutoff value with time-dependent receiver operating characteristic curve analysis. Additionally, we clarified the relationship between CAR and liver function or HCC progression. Median overall survival was 20.0 (95% confidence interval (CI), 17.2–22.6) months. The optimal CAR cutoff value was determined to be 0.108. Multivariate analysis showed that high CAR (≥ 0.108) (hazard ratio (HR), 1.915; 95% CI, 1.495–2.452), Eastern Cooperative Oncology Group performance status ≥ 1 (HR, 1.429), and α-fetoprotein ≥ 400 ng/mL (HR, 1.604) were independently associated with overall survival. Cumulative overall survival differed significantly between patients with low versus high CAR (p

Abstract For patients with cirrhosis, no definitive predictor of the efficacy and prognosis of tolvaptan treatment exists. We assessed the cisterna chyli’s utility as an optimal marker. We retrospectively enrolled 172 patients with cirrhosis. The effect of tolvaptan was evaluated using post-treatment survival time. The overall response to tolvaptan was 52.3%. The median cisterna chyli diameter was 4.1 mm. Of 172 patients, 100 were included in the pilot set and 72 in the validation set. According to the Youden index, the cisterna chyli diameter’s cutoff value was 4 mm, with a sensitivity, specificity, positive predictive value, negative predictive value, positive likelihood ratio, and negative likelihood ratio of 92%, 83%, 86%, 91%, 5.43, and 0.09, respectively, in the pilot set. The area under the curve of the cisterna chyli diameter for evaluating tolvaptan’s effect was 0.911 and 0.988 in the pilot and validation sets, respectively. During multivariate analysis, cisterna chyli narrowing and furosemide treatment were significant predictive factors for tolvaptan’s insufficient effect. Cumulative liver transplantation-free survival rates were significantly higher in patients with cisterna chyli dilatation than in those without (p = 0.028). Our findings suggest a strong association of cisterna chyli with tolvaptan treatment response in patients with cirrhosis and hepatic edema.

Background/Aim: There is no known report regarding the relationship of atezolizumab plus bevacizumab (Atez/Bev) treatment with muscle volume loss (MVL) in unresectable hepatocellular carcinoma (u-HCC) patients. This study aimed to elucidate the clinical relationship between MVL and Atez/Bev. Materials/Methods: From September 2020 to December 2021, 229 u-HCC patients treated with Atez/Bev and with muscle volume data obtained by computed tomography at the baseline available were analyzed (median age, 74 years; males, 186 (81.2%); ECOG PS 0/1, 221 (96.5%); HCV:HBV:alcohol:others=81:33:40:75; Child-Pugh A, 212 (92.6%); mALBI grade 1:2a:2b=79:60:90; BCLC 0:A:B:C =1:24:87:117; median observation period, 6.8 months). Japan Society of Hepatology criteria were used for definition of MVL and prognostic factors were retrospectively evaluated. Results: Multivariate Cox-hazard analysis of prognostic factors for progression-free survival (PFS) showed elevated alpha-fetoprotein (AFP) (≥100 ng/mL) (HR 1.848, 95%CI 1.264-2.702, P=0.002), modified albumin-bilirubin (mALBI) grade (≥2a) (HR 1.563, 95%CI 1.035-2.359, P=0.034), and MVL (HR 1.479, 95%CI 1.020-2.144, P=0.039) as significant factors. For overall survival (OS), significant factors included elevated AFP (≥100 ng/mL) (HR 3.564, 95%CI 1.856-6.844, P

Abstract Background and Aim Spleen stiffness measurement (SSM) is useful for assessing portal hypertension. It is unclear whether SSM values are appropriate because vibration‐controlled transient elastography (VCTE) does not generate B‐mode images. This study aimed to confirm whether the controlled attenuation parameter (CAP) measured in the spleen can predict the accuracy of SSM. Methods This retrospective study enrolled 349 patients who underwent SSM using VCTE from January 2012 to December 2020. Consecutive patients were classified into the pilot set (SSM and hepatic venous pressure gradient [HVPG] were measured) and the validation set (SSM was measured without HVPG). In the pilot set, scatter plots with a nonparametric contour line were created. Logistic regression analysis was performed to predict outliers outside the 50% contour line. Results The values of CAP could distinguish the outliers in scatter plots between the HPVG and SSM in both univariate and multivariate analyses (cutoff, 118 dB/m). The correlation of SSM with HVPG (r = 0.718; P 118 dB/m) group (r = 0.330; P

Abstract Introduction Fatty liver disease (FLD) is a surrogate condition for glucose intolerance development. FLD may involve normal or abnormal liver enzyme levels. Whether FLD is a risk factor for glucose intolerance, regardless of liver enzyme levels, remains unknown. We assessed relationships between the development of impaired fasting glucose (IFG) and FLD, liver enzyme abnormalities, and alcohol consumption. Materials and Methods We retrospectively evaluated 8,664 participants with more than two annual health check‐ups. Participants were classified according to sex, alcohol consumption, alanine aminotransferase (ALT) levels, and fatty liver status. Results In univariate analyses, IFG onset among men was related to normal or high ALT levels with FLD in the nonalcoholic and alcoholic groups (P‐trend

Abstract It was recently reported that hepatocellular carcinoma (HCC) patients with non-alcoholic steatohepatitis (NASH) are not responsive to immune-checkpoint inhibitor (ICI) treatment. The present study aimed to evaluate the therapeutic efficacy of lenvatinib in patients with non-alcoholic fatty liver disease (NAFLD)/NASH-related unresectable-HCC (u-HCC). Five hundred thirty u-HCC patients with Child–Pugh A were enrolled, and divided into the NAFLD/NASH (n = 103) and Viral/Alcohol (n = 427) groups. Clinical features were compared in a retrospective manner. Progression-free survival (PFS) was better in the NAFLD/NASH than the Viral/Alcohol group (median 9.3 vs. 7.5 months, P = 0.012), while there was no significant difference in overall survival (OS) (20.5 vs. 16.9 months, P = 0.057). In Cox-hazard analysis of prognostic factors for PFS, elevated ALT (≥ 30 U/L) (HR 1.247, P = 0.029), modified ALBI grade 2b (HR 1.236, P = 0.047), elevated AFP (≥ 400 ng/mL) (HR 1.294, P = 0.014), and NAFLD/NASH etiology (HR 0.763, P = 0.036) were significant prognostic factors. NAFLD/NASH etiology was not a significant prognostic factor in Cox-hazard analysis for OS (HR0.758, P = 0.092), whereas AFP (≥ 400 ng/mL) (HR 1.402, P = 0.009), BCLC C stage (HR 1.297, P = 0.035), later line use (HR 0.737, P = 0.014), and modified ALBI grade 2b (HR 1.875, P

Abstract We investigated the impact on survival of modified albumin–bilirubin (mALBI) grade versus Child–Pugh classification in patients with hepatocellular carcinoma (HCC) who received lenvatinib. A total of 524 patients with HCC who received lenvatinib were included. Univariate analysis showed that mALBI grade 2b/3 and Child–Pugh class B/C were significantly associated with survival [hazard ratio (HR), 2.471; 95% confidence interval (CI), 1.944–3.141 and HR, 2.178; 95%CI, 1.591–2.982]. In patients with a Child–Pugh score of 5, multivariate analysis showed that mALBI grade 2b/3 was independently associated with survival (HR, 1.814; 95%CI, 1.083–3.037). Conversely, among patients with mALBI grade 1/2a, there was no difference in survival between those with a Child–Pugh class of 5 or 6 (p = 0.735). Time-dependent receiver operating characteristic analysis showed that the ALBI score predicted survival better than the Child–Pugh score. The optimal cut-off value of the ALBI score for predicting survival was nearly the same as the value separating mALBI grades 2a and 2b. In conclusion, the mALBI grade was a better predictor of survival than the Child–Pugh classification in patients with unresectable HCC who received lenvatinib therapy.

Hepatocellular carcinoma has been considered to disseminate through the tumor blood drainage area. To improve curation rates, treatment should cover this area as it may contain satellite lesions. This retrospective study aimed to investigate whether radiofrequency ablation (RFA) completely covering the blood drainage area can improve the overall and disease‐free survival. We enrolled 526 patients who underwent computed tomography during hepatic arteriography following RFA from April 2001 to May 2019. Patients were categorized into a covered group in which the blood drainage area was completely covered by RFA and a noncovered group in which coverage was incomplete. The primary endpoint was the overall survival rate; secondary outcomes included disease‐free survival rate, distant intrahepatic and local recurrence rate, and changes in the Child‐Pugh score. There were no significant differences in baseline characteristics between the two groups. Cumulative overall survival rates were significantly higher in the covered group than in the noncovered group (hazard ratio, 0.63; 95% confidence interval, 0.48‐0.84; P = 0.002). On multivariate Cox proportional hazard model analysis, age

Abstract Endoplasmic reticulum (ER) stress plays an important role in hepatocyte degeneration, especially in patients with chronic liver injury. Protein kinase R-like endoplasmic reticulum kinase (PERK) is a key molecule in ER stress. PERK may contribute to apoptotic cell death in HCC, however the details of the mechanism are not clear. In this study, we identified PERK-associated molecules using transcriptome analysis. We modulated PERK expression using a plasmid, tunicamycin and siRNA against PERK, and then confirmed the target gene expression with real-time PCR and Northern blotting. We further analyzed the apoptotic function. Transcriptome analysis revealed that expression of the RNA component of mitochondrial RNA processing endoribonuclease (RMRP), which is a long noncoding RNA, was strongly correlated with the function of PERK. The expression of RMRP was correlated with the expression of PERK in experiments with the siRNA and PERK plasmid in both HCC cell lines and human HCC tissue. Furthermore, RMRP downregulation induced apoptotic cell death. RMRP is downregulated by PERK, which induces apoptosis in HCC. RMRP could be a new therapeutic target to regulate HCC in patients with chronic liver diseases associated with ER stress.

Abstract Background Causes of non-alcoholic fatty liver disease and its progression include visceral fat accumulation and loss of muscle mass; however, which of the two phenomena is more critical is unclear. Therefore, we intended to examine the relationship between body composition and non-alcoholic fatty liver disease progression as indicated by fibrosis and the non-alcoholic fatty liver disease activity score. Methods This cross-sectional study comprised 149 patients (55 men; age, 20–76 years) treated for non-alcoholic fatty liver disease between December 2010 and January 2020. Body composition measurements, histological examinations of liver samples, and comprehensive blood chemistry tests were performed. The relationship between body composition and non-alcoholic fatty liver disease histology findings was analyzed using the logistic regression model. Results Fibrosis was significantly and inversely correlated with muscle mass and appendicular skeletal muscle mass and significantly and positively correlated with fat mass, fat mass/height squared, visceral fat area, and waist-hip ratio (P

Background/Aim: An effective postprogression treatment of lenvatinib (LEN) against unresectable hepatocellular carcinoma (u-HCC) has not been established. We aimed to elucidate the clinical role of continuing LEN beyond progression of disease (PD). Methods: From March 2018 to October 2020, 99 u-HCC patients, in whom PD was confirmed (male:female = 78:21, median age 72 years, Child-Pugh A = 99, Barcelona Clinic Liver Cancer stage A:B:C = 2:43:54, LEN as first-line = 55), were enrolled (stopped LEN at PD [A group], n = 26; continued LEN beyond PD [B group], n = 73). Radiological response was evaluated with RECIST 1.1. Clinical features and prognostic factors for overall survival (OS) were retrospectively investigated using inverse probability weighting (IPW) calculated by propensity score. Results: Median time to progression, best response, and modified albumin-bilirubin grade (mALBI) at both baseline and PD did not show significant difference between the groups. Postprogression treatment in the A group was best supportive care in 17, sorafenib in 4, regorafenib in 3, ramucirumab in 1, and hepatic arterial infusion chemotherapy in 1. After adjusting with IPW, the B group showed better prognosis in regard to OS after PD and OS after introducing LEN than the A group (10.8/19.6 vs. 5.8/11.2 months, p < 0.001, respectively). In IPW-adjusted Cox hazard multivariate analysis, significant prognostic factors for OS after PD were mALBI 2b/3 at PD (HR 1.983, p = 0.021), decline of Eastern Cooperative Oncology Group performance status (ECOG PS) from baseline at PD (HR 3.180, p < 0.001), elevated alpha-fetoprotein (≥100 ng/mL) at introducing LEN (HR 2.511, p = 0.004), appearance of new extrahepatic metastasis (HR 2.396, p = 0.006), positive for hand-foot skin reaction (HFSR) before PD (any grade) (HR 0.292, p < 0.001), and continuing LEN beyond PD (HR 0.297, p < 0.001). Conclusion: When ECOG PS and hepatic reserve function permit, continuing LEN treatment beyond PD, especially in u-HCC patients showed HFSR during LEN treatment, might be a good therapeutic option, at least until a more effective drug as a postprogression treatment after LEN failure is developed.

Abstract Background Although atezolizumab plus bevacizumab (Atez/bev) treatment has been developed for unresectable hepatocellular carcinoma (u‐HCC), changes in hepatic function during therapy have yet to be reported. Aim This retrospective clinical study aimed to elucidate early responses to Atez/Bev. Methods From September 2020 to April 2021, 171 u‐HCC patients undergoing Atez/Bev treatment were enrolled (BCLC stage A:B:C:D = 5:68:96:2). Of those, 75 had no prior history of systemic treatment. Relative changes in hepatic function and therapeutic response were assessed using albumin‐bilirubin (ALBI) score and Response Evaluation Criteria in Solid Tumors (RECIST), ver. 1.1, respectively. Results In initial imaging examination findings, objective response rates for early tumor shrinkage and disease control after 6 weeks (ORR‐6W/DCR‐6W) were 10.6%/79.6%. Similar response results were observed in patients with and without a past history of systemic treatment (ORR‐6W/DCR‐6W = 9.7%/77.8% and 12.2%/82.9%), as well as patients in whom Atez/Bev was used as post‐progression treatment following lenvatinib (ORR‐6W/DCR‐6W = 7.7%/79.5%), for which no known effective post‐progression treatment has been established. In 111 patients who underwent a 6‐week observation period, ALBI score was significantly worsened at 3 weeks after introducing Atez/Bev (−2.525 ± 0.419 vs −2.323 ± 0.445, p

Abstract Background/aim We assessed suitable factors indicating newly developed lenvatinib (LEN) treatment for unresectable hepatocellular carcinoma (u‐HCC) by investigating real‐world clinical features of patients. Materials/methods One hundred fifty two u‐HCC patients, who receive LEN treatment from March to December 2018, were enrolled. (Child‐Pugh score [CPS] 5/6/7/8 = 76/61/13/2, modified albumin‐bilirubin grade [mALBI] 1/2a/2b/3 = 53/35/60/4). Clinical features were evaluated retrospectively. Results Overall‐response rate (ORR)/disease control rate (DCR) at 1 month after starting LEN were 38.7%/86.0%, respectively. Estimated median time to progression (TTP) was 7.0 months, while median survival time was not reached within the observation period. CPS (≥7) and past history of tyrosine‐kinase inhibitor (TKI) were not significant prognostic factors. mALBI ≥2b was an only significant prognostic factor (HR 4.632, 95%CI 1.649‐13.02, P = 0.004) in Cox‐hazard multivariate analysis. In patients with Child‐Pugh A, c‐index/Akaike's information criterion (AIC) of prognostic predictive value of mALBI were superior to CPS (0.682/135.6 vs 0.652/138.7), while those of stopping LEN also showed that mALBI was better (0.575/447.3 vs 0.562/447.8). Additional analysis of patients with good mALBI (1/2a) revealed that time to stopping LEN was significantly shorter in those with the adverse event (AE) of appetite loss (any grade) than those without (P = 0.006) and body mass index (BMI) was also lower in patients with that AE (20.3 ± 3.0 vs 23.6 ± 4.0kg/m2, P

The relationship between advanced nonalcoholic steatohepatitis (NASH) and plasma fatty acid composition remains unknown. We aimed to examine the plasma fatty acid composition in biopsy-confirmed nonalcoholic fatty liver disease (NAFLD) and evaluate the relationship between histological findings and fatty acid composition. Overall, 235 patients (134 women) with NAFLD were enrolled. Comprehensive blood chemistry tests and histological examinations of liver samples were conducted. Multivariate analyses adjusted for age, sex, body mass index, alanine aminotransferase, hemoglobin A1c, creatinine, total cholesterol, triglyceride, and NAFLD Activity Score values showed that lower levels of arachidic, behenic, α-linolenic, eicosatetraenoic, docosapentaenoic, and docosahexaenoic acids and higher levels of mead acid were associated with fibrosis stage 3–4. Furthermore, higher lauric acid, myristic acid, and palmitic acid levels and monounsaturated fatty acids such as palmitoleic acid and oleic acid were significantly associated with high NAS in analyses adjusted for the same factors and fibrosis stage. The plasma fatty acid composition was associated with the histological evidence of NASH. Increased synthesis of fatty acids is associated with NASH; insufficient intake of n-3 essential fatty acids and reduced elongation of fatty acids are associated with fibrosis in NASH. These features may help clinicians to understand and treat advanced NASH cases.

BackgroundHepatic venous pressure gradient (HVPG) is the gold standard index for evaluating portal hypertension; however, measuring HVPG is invasive. Although transient elastography (TE) is the most common procedure for evaluating organ stiffness, accurate measurement of spleen stiffness (SS) is difficult. We developed a device to demonstrate the diagnostic precision of TE and suggest this technique as a valuable new method to measure SS.MethodsOf 292 consecutive patients enrolled in this single-centre, translational, cross-sectional study from June through September in 2019, 200 underwent SS measurement (SSM) using an M probe (training set, n = 130; inspection set, n = 70). We performed TE with B-mode imaging using an ultrasound-fusion method, printed new devices with a three-dimensional printer, and attached the magnetic position sensor to the convex and M probes. We evaluated the diagnostic precision of TE to evaluate the risk of esophagogastric varices (EGVs).ResultsThe median spleen volume was 245 mL (range, 64-1,720 mL), and it took 2 minutes to acquire a B-mode image using the ultrasound-fusion method. The median success rates of TE were 83.3% and 57.6% in patients with and without the new device, respectively (pConclusionsThe SS can be precisely measured using this new device with TE and ultrasound-fusion method. Similarly, we can estimate the bleeding risk due to EGV using this method.

A 58-year-old man was diagnosed with advanced hepatocellular carcinoma with portal vein tumor thrombosis (PVTT). The tumors were multiple and existed in both lobes. Drug-eluting beads transcatheter arterial chemoembolization (DEB-TACE) was performed for the tumors in the left lobe. Embosphere and Hepasphere were selected for embolization of the arterioportal shunt, followed by loaded epirubicin infusion into the left hepatic artery. Computed tomography showed reduction of PVTT. However, liver failure progressed, and the patient died 67 days after DEB-TACE. Autopsy showed that the beads reached the tumor thrombosis in the portal vein. The prognosis of hepatocellular carcinoma with PVTT is poor. Although there are no established treatments for unresectable PVTT, DEB-TACE might be a useful option for such cases.

Hepatic stellate cells (HSCs) were reported to promote the progression of hepatocellular carcinoma (HCC), however its mechanism is uncertain. We previously reported that protein kinase R (PKR) in hepatocytes regulated HCC proliferation. In this study, we focused on the role of PKR in HSCs, and clarified the mechanism of its association with HCC progression. We confirmed the activation of PKR in a human HSC cell line (LX-2 cell). IL-1β is produced from HSCs stimulated by lipopolysaccharide (LPS) or palmitic acid which are likely activators of PKR in non-alcoholic steatohepatitis (NASH). Production was assessed by real-time PCR and ELISA. C16 and small interfering RNA (siRNA) were used to inhibit PKR in HSCs. The HCC cell line (HepG2 cell) was cultured with HSC conditioning medium to assess HCC progression, which was evaluated by proliferation and scratch assays. Expression of PKR was increased and activated in stimulated HSCs, and IL-1β production was also increased molecular. Key molecules of the mitogen-activated protein kinase pathway were also upregulated and activated by LPS. Otherwise, PKR inhibition by C16 and PKR siRNA decreased IL-1β production. HCC progression was promoted by HSC-stimulated conditioning medium although it was reduced by the conditioning medium from PKR-inhibited HSCs. Moreover, palmitic acid also upregulated IL-1β expression in HSCs, and conditioning medium from palmitic acid-stimulated HSCs promoted HCC proliferation. Stimulated HSCs by activators of PKR in NASH could play a role in promoting HCC progression through the production of IL-1β, via a mechanism that seems to be dependent on PKR activation.

PurposeWe have developed a diagnostic technique to evaluate hepatic steatosis using the attenuation coefficient (ATT) in ultrasound B mode imaging. A controlled attenuation parameter (CAP) by vibration-controlled transient elastography (VCTE) has also been used to evaluate hepatic steatosis. As that method uses ultrasound A mode, visualizing the liver in real time is difficult. We designed this clinical study to evaluate the diagnostic advantage of our technique using ATT compared to CAP.Materials and methodsThe study group included 94 patients with chronic liver disease who had undergone both ATT and CAP assessment at the time of liver biopsy. The M-probe and XL-probe were used for CAP measurement. Data for ATT and CAP were compared as a function of the steatosis grade.ResultsThe area under the receiver operating characteristic curve (AUC-ROCs) for ATT and PAC as a function of the steatosis grade were as follows: grade 1, 0.74 and 0.81; grade 2, 0.80 and 0.85; and grade 3, 0.96 and 0.98, respectively.ConclusionThe accuracy of steatosis grade diagnosis using ATT was the same as that using CAP, with no significant differences and with the added advantage of B mode ultrasound being more convenient and rapid, compared to A mode ultrasound, particularly for patients with subcutaneous fat thickness ≥2 cm.
