Abstract Background and Aims We aimed to evaluate the efficacy and safety of durvalumab plus tremelimumab (Dur + Tre) combination therapy in patients with unresectable hepatocellular carcinoma (uHCC) in clinical practice. Methods We retrospectively evaluated 37 patients with uHCC from our institutions between April 2023 and January 2024. Patients were divided into first‐ and later‐line groups for analysis of antitumor efficacy, adverse events (AEs), and transition rate to second‐line treatment according to the Response Evaluation Criteria in Solid Tumors (RECIST). Results The disease control rate (DCR) for the first‐line group was 80.9%, which was significantly higher than that for the later‐line group (50%). The incidence of immune‐related AEs (irAEs) was 24.3%, with grade 3 or higher irAEs including increased transaminase (8.1%), diarrhea (8.1%), and adrenal insufficiency (2.7%). The rates of drug withdrawal and discontinuation owing to AEs were 23.8% and 19%, respectively, in the first‐line treatment and 31.2% and 12.5%, respectively, in the later‐line treatment, with no significant difference. Analysis of changes in liver reserve using the albumin–bilirubin (ALBI) score showed no obvious loss of liver reserve for up to 12 weeks. The transition rate from first‐ to second‐line therapy after progressive disease (PD) was as high as 94.7%. Conclusion The efficacy and safety of Dur + Tre in clinical practice were comparable to those reported in a recent phase III trial. The first‐line Dur + Tre therapy had a higher DCR than that of the later lines, and the transition rate to second‐line therapy was considerably high, suggesting that Dur + Tre therapy would be more beneficial in first‐line treatment.

Abstract Portal vein thrombosis (PVT) worsens the long-term prognosis of patients with cirrhosis; however, the optimal treatment remains to be determined. Reports on the efficacy of direct oral anticoagulants are increasing, and further evidence is needed. Therefore, we investigated the effectiveness of treatment with edoxaban in patients with PVT. We retrospectively reviewed the outcomes of edoxaban and warfarin as antithrombotic therapies for PVT. The median overall survival time was 4.2 years in patients with PVT, with a 1-year survival rate of 70.7% and a 5-year survival rate of 47.9%. The leading cause of death was hepatocellular carcinoma. The overall response rate for thrombolysis in the edoxaban group was 76.7% compared to 29.4% in the warfarin group, and edoxaban significantly improved PVT compared to warfarin. In addition, edoxaban provided long-term improvement of PVT. Warfarin, on the other hand, was temporarily effective but did not provide long-term benefits. The Child–Pugh and albumin-bilirubin scores did not change after edoxaban or warfarin use. No deaths occurred due to adverse events associated with edoxaban or warfarin. Edoxaban as a single agent can achieve long-term recanalization without compromising the hepatic reserves. Edoxaban is easy to initiate, even in an outpatient setting, and could become a major therapeutic agent for the treatment of PVT.

Abstract Background Hepatocellular carcinoma (HCC) in autoimmune hepatitis (AIH) was considered rare but is increasing with prolonged prognosis. Its impact on the overall prognosis of AIH is unknown, and treatment has not been established. Aim To investigate the risk factors and prognosis of HCC in patients with AIH and identify appropriate management strategies. Methods We studied patients with AIH including background liver disease, sex, age, complications, treatment, response to treatment, liver fibrosis, prognosis, and treatment. Results In 131 patients, deaths due to liver failure were more common early after the onset of AIH; however, deaths due to HCC increased gradually. HCC was observed in 12 patients (median age, 70 years; male/female, 4/8; cirrhosis at onset, 11; median time to carcinogenesis, 7 years). Cirrhosis at diagnosis was identified as a risk factor for carcinogenesis in the multivariate analysis (odds ratio, 41.36; p

Abstract Hepatocellular carcinoma invasion of the bile duct is rare and has a poor prognosis. A 77‐year‐old man presented at the emergency department with persistent pain in the right hypochondrium. Blood tests and imaging studies revealed a 70‐mm occupying lesion in the right lobe of the liver and dilated intrahepatic bile ducts. He was diagnosed with obstructive jaundice and cholangitis. Imaging studies showed an internal mass with poor contrast effects. A liver biopsy was performed to confirm the diagnosis and hepatocellular carcinoma was suspected. Endoscopic retrograde cholangiopancreatography, endoscopic ultrasound, and peroral cholangioscopy were performed to determine the treatment strategy. The bile duct invasion did not extend to the porta hepatis; therefore, right hepatic lobectomy and radical resection were performed. Bile duct invasion in hepatocellular carcinoma is rare and often difficult to diagnose by computed tomography or conventional endoscopic retrograde cholangiopancreatography. However, endoscopic ultrasound and peroral cholangioscopy enable safe and accurate diagnosis of the extent of invasion.

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 Indications of drug therapies to elderly patients with hepatocellular carcinoma (HCC) should be carefully determined. The current study assessed the safety and efficacy of molecular targeted agents (MTAs) in the elderly patients with HCC, and identified factors associated with prognosis in a real‐world clinical setting. Methods In a retrospective observational study, clinical data of patients with unresectable HCC treated with sorafenib or lenvatinib as first‐line treatment at our hospital between 2011 and 2022, were investigated. Clinical parameters, therapeutic effects, adverse events (AEs), and prognosis were evaluated separately for the non‐elderly (

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 Background and Aim Nonalcoholic fatty liver disease (NAFLD) is closely associated with metabolic syndrome. This study was performed to examine the association between NAFLD and each factor of metabolic syndrome and to identify the factors that are most strongly associated with NAFLD in participants undergoing health checkups. Methods We studied 6538 participants who underwent a health checkup from 2017 to 2018 in our institution. Participants with alcohol intake exceeding 20 g/day or with other chronic liver diseases were excluded. Fatty liver was detected by ultrasonography. Results In total, 4310 participants were enrolled, and 28.4% had fatty liver (NAFLD). The prevalence of NAFLD was highest in the diabetes mellitus (DM)‐only group than in the dyslipidemia‐only or hypertension‐only group. The DM‐only group was the only group whose prevalence of NAFLD was >50% in the overall study and in males. The prevalence of NAFLD was higher in males than in females in the DM‐only, hypertension‐only, and dyslipidemia‐only groups. The prevalence of NAFLD was >70% in the dyslipidemia and DM combined group. Multivariate analysis showed that gender and HbA1c were the independent factors most strongly associated with NAFLD. The cutoff value for HbA1c by receiver operating characteristic curve analysis was 5.8% (sensitivity, 57.9%; specificity, 72.6%; area under the curve, 0.70). Conclusion NAFLD was most strongly associated with DM, among the various components of metabolic syndrome. We strongly recommend abdominal ultrasonography to detect NAFLD in patients with an HbA1c of ≥5.8% in general practice and during health checkups.

Chronic hepatitis C virus (HCV) infection is associated with an increased risk of extrahepatic cancers, particularly non-Hodgkin lymphoma. The introduction of direct-acting antivirals (DAAs) has revolutionized HCV therapy, resulting in high cure rates. However, concerns have been raised about potential effects on cancer risk. This review summarizes the current evidence on extrahepatic cancer risk in HCV-infected patients treated with DAAs. We examined epidemiologic data on HCV-associated extrahepatic cancers and explored potential mechanisms linking HCV to carcinogenesis outside the liver. Studies evaluating cancer outcomes after DAA therapy were critically reviewed while considering methodological challenges. While some studies suggested a reduced risk of extrahepatic cancers after DAA therapy, others showed no significant change. Limitations included short follow-up periods and confounding variables. Immunological changes following rapid HCV clearance may have complex effects on cancer risk. Long-term prospective studies and mechanistic investigations are needed to fully elucidate the relationship between DAA therapy and extrahepatic cancer risk in HCV patients. Clinicians should remain vigilant for extrahepatic malignancies in this population.

Abstract Aim Multiple studies have revealed the correlation between gut microbiome and the response to checkpoint inhibitors (CPIs) in patients with cancer, and oral administration of butyrate‐producing enterobacteria has been reported to enhance the efficacy of CPIs. However, the effects of enterobacteria on patients with hepatocellular carcinoma (HCC) are not well understood. Methods In this retrospective multicenter study, we enrolled 747 patients with advanced HCC, treated with atezolizumab and bevacizumab combination therapy. Tumor response, survival, and adverse effects were compared between 99 patients who ingested drugs containing butyric acid‐producing enterobacteria (butyric acid group) and the remaining patients (control group). Results Objective response and disease control rates in butyric acid group (29.7% and 77.8%, respectively) were higher than those in the control group (26.4% and 72.7%, respectively). However, the differences were not statistically significant (p = 0.543 and p = 0.222, respectively). No difference in median survival time was observed between the two groups (20.0 months and 21.4 months, respectively; p = 0.789), even after matching the backgrounds of the patients with propensity scores (p = 0.714). No adverse effects occurred upon the administration of butyrate‐producing bacteria. However, proteinuria (41.4% vs. 30.9%; p = 0.041), fever (17.2% vs. 10.2%, p = 0.036), and diarrhea (15.2% vs. 6.2%; p = 0.001) occurred more frequently in the butyric acid group. Conclusion Butyrate‐producing bacteria does not enhance the efficacy of atezolizumab–bevacizumab combination therapy in patients with HCC.

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 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 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 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 Aim We analyzed the association between the modified albumin–bilirubin (mALBI) grade and therapeutic efficacy of atezolizumab plus bevacizumab (Atezo+Bev) for the treatment of unresectable hepatocellular carcinoma (u‐HCC). Methods In this retrospective observational study, we included 71 u‐HCC patients treated with Atezo+Bev between September 2020 and September 2021. Patients were grouped corresponding to the mALBI grade at the start of treatment (mALBI 1+2a or mALBI 2b+3) and analyzed for therapeutic effect and the transition rate to secondary treatment. Results According to the Response Evaluation Criteria in Solid Tumors, the overall response rate was significantly higher for the mALBI 1+2a group, than for the mALBI 2b+3 group, with 26.2% and 3.4%, respectively. The progression‐free survival (PFS) was significantly longer in the mALBI 1+2a group (10.5 months) than in the mALBI 2b+3 group (3.0 months). In the multivariate analysis, an mALBI of 1+2a was found to be an independent factor of PFS. The rate of second‐line treatment with multi‐targeted agents was also significantly higher in the mALBI 1+2a group. Conclusions In real‐world practice, Atezo+Bev treatment might have higher therapeutic efficacy in u‐HCC patients with mALBI 1+2a.

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 Despite reports of hepatocellular carcinoma (HCC) in patients with chronic hepatitis C virus (HCV) infection after achieving sustained virological response (SVR), only few studies have demonstrated the incidence of other (non‐HCC) malignancies. This study aimed to clarify the incidence, survival probability, and factors associated with malignancy, especially non‐HCC malignancies, in patients with chronic HCV infection after achieving SVR. In this retrospective study, records of 3580 patients with chronic HCV infection who achieved SVR following direct‐acting antiviral (DAA) treatment were analyzed. The cumulative post‐SVR incidence of non‐HCC malignancies was 0.9%, 3.1%, and 6.8% at 1, 3, and 5 years, respectively. The survival probability for patients with non‐HCC malignancies was 99.1%, 78.8%, and 60.2% at 1, 3, and 5 years, respectively, and the rate was significantly lower than that for patients with HCC. The Cox proportional hazards regression model identified Mac‐2‐binding protein glycan isomer (M2BPGi) cutoff index (COI) ≥ 1.90 at baseline and ≥ 1.50 at 12 weeks following DAA treatment as significant and independent factors associated with the post‐SVR incidence of non‐HCC malignancies. Furthermore, patients with either M2BPGi COI ≥ 1.90 at baseline or M2BPGi COI ≥ 1.50 at SVR12 had a significantly higher risk of post‐SVR incidence of non‐HCC malignancies than of HCC. Conclusion: M2BPGi measurements at baseline and SVR12 may help predict the post‐SVR incidence of non‐HCC malignancies in patients with chronic HCV infection who achieved SVR following DAA treatment. Early identification of these patients is critical to prolong patient survival.

Abstract Nalfurafine hydrochloride, a selective κ-opioid receptor agonist has been approved for pruritus in patients with chronic liver disease. However, not all patients respond to nalfurafine hydrochloride. The aim of this study was to clarify the efficacy of nalfurafine hydrochloride. The subjects were patients with chronic liver disease complicated by pruritus who were treated with nalfurafine hydrochloride between May, 2015, and May, 2021. The degree of pruritus was evaluated based on the Visual Analog Scale (VAS) score and the Kawashima’s pruritus score. Nalfurafine hydrochloride 2.5 μg was orally administered once a day for 12 weeks. A decrease in the VAS score of ≥ 25 mm or the Kawashima’s pruritus score of ≥ 1 scores was designated as relevant response. The former of ≥ 50 mm or the latter of ≥ 2 scores as remarkable response. The 326 patients who were evaluated the efficacy at 12 weeks. The median time suffering from pruritus to administration of nalfurafine hydrochloride was 4 months. The median VAS score improved from 70.0 mm before administration to 40.0 and 30.0 mm at 4 and 12 weeks of treatment, respectively. On multivariate analysis, shorter itching period and lower FIB-4 index value were extracted as the independent factors related to remarkable responder. On multivariate analysis, shorter itching period was extracted as the only independent factor related to relevant responder. In conclusion, this study suggested nalfurafine hydrochloride treatment markedly improves pruritus in patients with chronic liver disease. A short pruritus period and less-advanced fibrosis were associated with response to nalfurafine hydrochloride.

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

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

Background: The over-the-scope clip (OTSC) is a highly effective clipping device for refractory gastrointestinal disease. However, Japanese data from multicenter studies for anastomotic leakage (AL) involving a secondary fistula after gastrointestinal surgery are lacking. Therefore, this study evaluated the efficacy and safety of OTSC placement in Japanese patients with such conditions. Methods: We retrospectively collected data from 28 consecutive patients from five institutions who underwent OTSC-mediated closure for AL between July 2017 and July 2020. Results: The AL and fistula were located in the esophagus (3.6%, n = 1), stomach (10.7%, n = 3), small intestine (7.1%, n = 2), colon (25.0%, n = 7), and rectum (53.6%, n = 15). The technical success, clinical success, and complication rates were 92.9% (26/28), 71.4% (20/28), and 0% (0/28), respectively. An age of 7 days (84.2%), and the use of simple suction (78.9%) and anchor forceps (80.0%) were associated with higher clinical success rates. Conclusion: OTSC placement is a useful therapeutic option for AL after gastrointestinal surgery.

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.

Abstract Fibrosis-4 index, a conventional biomarker for liver fibrosis stage, is confounded by age and hepatitis activity grade. The current retrospective multicenter study aimed to formulate the novel indices of liver fibrosis by mathematically combining items of peripheral blood examination and to evaluate ability of prognosis prediction. After a novel index was established in a training cohort, the index was tested in a validation cohort. Briefly, a total of 426 patients were enrolled in a training cohort. Albumin and platelet most strongly correlated to fibrosis stage among blood examination. Albumin platelet product (APP) = Albumin × platelet/1000 could differentiate the four stages of liver fibrosis (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 and Aim Although tenofovir alafenamide (TAF), as well as entecavir (ETV), is widely used as first‐line treatment for patients with chronic hepatitis B, there are only a few studies comparing sequential therapy from ETV to TAF and continuous ETV monotherapy in patients with maintained virologic response to ETV. Methods In a retrospective multicenter study, we investigated the efficacy and safety of sequential therapy from ETV to TAF (ETV‐TAF group) and compared them with continuous ETV monotherapy (ETV group), using propensity score matching, in chronic hepatitis B patients. Results From 442 patients, we analyzed 142 patients from each group comprising 71 patients matched for several data, including age, HBV genotype, hepatitis B envelope antigen, cirrhosis, alanine aminotransferase, platelet count, prior ETV monotherapy period, and hepatitis B surface antigen (HBsAg) change during prior ETV monotherapy. In the ETV‐TAF group, HBsAg levels significantly decreased from baseline to 48 weeks after switching to TAF (−0.02 log IU/mL, P = 0.038). HBcrAg levels also significantly decreased after switching to TAF (−0.1 log IU/mL, P = 0.004). However, there were no significant differences in the reduction of HBsAg and HBcrAg levels between the ETV‐TAF and ETV groups. There was no significant difference in the change of estimated glomerular filtration rate levels from baseline to 48 weeks between the two groups. Conclusions The present study indicated that the efficacy, especially of the HBsAg‐reducing action, and safety of sequential therapy from ETV to TAF were similar to those of continuous ETV monotherapy among chronic hepatitis B patients with maintained virologic response to ETV.

Abstract Introduction Clinical trials of direct-acting antivirals for patients with decompensated cirrhosis have been conducted, but there is limited information on the medicinal applications in clinical settings. We aimed to evaluate the safety and efficacy of sofosbuvir/velpatasvir for decompensated cirrhotic patients with genotypes 1 and 2 in real-world clinical practice. Methods A prospective, multicenter study of 12-week sofosbuvir/velpatasvir was conducted for patients with decompensated cirrhosis at 33 institutions. Results The cohort included 71 patients (52 genotype 1, 19 genotype 2): 7 with Child–Pugh class A, 47 with class B, and 17 with class C (median score 8; range 5–13). The albumin–bilirubin (ALBI) score ranged from − 3.01 to − 0.45 (median − 1.58). Sixty-nine patients (97.2%) completed treatment as scheduled. The overall rate of sustained virologic response at 12 weeks post-treatment (SVR12) was 94.4% (67/71). SVR12 rates in the patients with Child–Pugh classes A, B, and C were 85.7%, 97.9%, and 88.2%, respectively. Among 22 patients with a history of hepatocellular carcinoma treatment, 20 (90.9%) achieved SVR12. The Child–Pugh score and ALBI grade significantly improved after achieving SVR12 (p = 7.19 × 10−4 and 2.42 × 10−4, respectively). Notably, the use of diuretics and branched-chain amino acid preparations significantly reduced after achieving SVR12. Adverse events were observed in 19.7% of the patients, leading to treatment discontinuation in two patients with cholecystitis and esophageal varices rupture, respectively. Conclusion Twelve weeks of sofosbuvir/velpatasvir in real-world clinical practice yielded high SVR rates and acceptable safety profiles in decompensated cirrhotic patients with genotypes 1 and 2. Achievement of SVR not only restored the liver functional reserve but also reduced or spared the administration of drugs for related complications.

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

Non-alcoholic steatohepatitis (NASH) is a common chronic liver disease with no decisive treatment. The sodium glucose cotransporter 2 (SGLT2) inhibitor ipragliflozin was developed as a new oral hypoglycemic drug, which can improve NASH via an insulin-independent glucose-lowering effect by inhibiting glucose reabsorption in the renal proximal tubules. However, ipragliflozin appears to modulate steatosis or inflammation via different pathways. To elucidate the new mechanism of ipragliflozin for the treatment of NASH, we evaluated its effects in a NASH mouse model (STAM mice) with beta cell depletion, and compared the expression of microRNAs (miRNAs) in STAM mice treated with or without ipragliflozin (16.7 μg/day for 5 weeks). Ipragliflozin reduced aspartate transaminase and alanine aminotransferase levels, along with reduced hepatic steatosis, hepatocyte ballooning, lobular inflammation, and liver fibrosis. In addition, ipragliflozin upregulated mitochondrial transport-related and antioxidant defensive system-related genes in the liver. Among 2555 mouse miRNA probes, miR-19b-3p was commonly differentially expressed with ipragliflozin treatment for 5 weeks in both the liver and serum but in different directions, with a decrease in the liver and increase in the serum. Therefore, ipragliflozin can improve NASH development likely through the antioxidative stress pathway and by regulating miR-19b-3p.

Computed tomography (CT) is often used in the diagnosis of sarcopenia. In this study, we validated the assessment of sarcopenia by the psoas muscle volume using versatile software. The study involved a retrospective analysis of data from 190 patients with liver disease who underwent grip-strength testing and abdominal pelvic computed tomography. To assess sarcopenia, SYNAPSE 3D was used to obtain the skeletal muscle index, the psoas muscle index (PMI), and the simple method. We also used the recently proposed PMI cutoff values, for which the usefulness has been evaluated (O-PMI). The cutoff value of the psoas muscle volume index (PMVI) was determined using one of the diagnostic methods as the gold standard. All diagnostic methods showed that patients with sarcopenia had shorter survival, with O-PMI having the highest hazard ratio (HR) (HR, 6.12; 95% confidence interval [CI], 2.6–14.41; p < 0.001). Even when sarcopenia could not be diagnosed by O-PMI, low PMVI was associated with shorter survival (HR, 3.53; 95% CI, 1.34–9.32; p = 0.01). PMVI may be useful in the evaluation of sarcopenia, including the identification of poor overall survival in cases that cannot be diagnosed by O-PMI, which is considered more useful than PMI.

Abstract Cutaneous metastases from hepatocellular carcinoma (HCC) are rare and mostly occur on the face, scalp, chest, and shoulders, often with rapid growth. We report the case of an 86‐year‐old man who presented to our hospital with a mass, 5 cm in diameter, on the left side of his nose. His past history included a partial hepatectomy for HCC, 3 years previously, and a subsequent diagnosis of lung metastases. Skin and gingival biopsies confirmed the diagnosis of metastatic HCC and he was treated with immunotherapy followed by transarterial embolization (TAE). The latter resulted in a significant reduction in the cutaneous tumour mass.

Abstract Background Ten to forty percent of nonalcoholic steatohepatitis (NASH) and HCV-related chronic liver disease (CLD-C) patients have antinuclear antibodies (ANAs). However, the relationship between autoimmune response and insulin resistance remains uncertain among those patients. The primary purpose of this study was to investigate whether or not ANA status was associated with the development of insulin resistance and obesity in NASH and CLD-C patients. Methods Degrees of hepatic fibrosis and steatosis were evaluated by the classification proposed by Brunt et al. Obesity and insulin resistance were estimated by calculating body mass index and the value of homeostasis model of for assessment of insulin resistance (HOMA-IR), respectively. A revised scoring system was applied to the diagnosis of autoimmune hepatitis (AIH). Serum B-lymphocyte activating factor (BAFF) levels were determined, using an ELISA technique. Results Ten of 25 (40%) NASH patients and 9 of 22 (41%) CLD-C patients had ANAs, though the titers were weak in most patients. Only one NASH patient met the category of “definite” AIH among the enrolled patients. Serum IgG levels were significantly higher in NASH and CLD-C patients with ANAs than in those without ANAs, and NASH and CLD-C patients with ANAs had significantly higher HOMA-IR values than those without ANAs (6.81 ± 3.36 vs. 4.00 ± 2.57, p = 0.0305, 3.01 ± 1.31 vs. 1.28 ± 0.50, p = 0.0011). CLD-C patients with ANAs had more advanced hepatic fibrosis and steatosis than those without ANAs, while ANA status was not associated with hepatic fibrosis or steatosis in NASH patients. Obesity was independent of ANA status in both subjects. Serum BAFF levels were significantly higher in CLD-C patients with ANAs than those in CLD-C patients without ANAs (1303 ± 268 vs. 714 ± 143 pg/ml, p = 0.0036). A close correlation between serum BAFF level and the HOMA-IR value was observed in CLD-C patients (r = 0.467, p = 0.0485). Conclusion Our data suggest that NASH and CLD-C patients with ANAs have more severe insulin resistance than those without ANAs. More advanced insulin resistance deriving from excessive BAFF production may result in severe hepatic fibrosis and steatosis in CLD-C patients with ANAs.

Diaphragmatic hernia (DH) is a defect, which can be congenital or can develop later in life. Moreover, chromosomal and genetic abnormalities, environmental exposures, and nutritional deficiencies may be related to the development of congenital DH. In contrast, the risk factors of acquired DH include traumas, such as blunt injuries due to traffic accidents and surgical procedures. We report the case of a 71-year-old man admitted to our gastroenterology department for the treatment of esophageal varices. Four days after the endoscopic treatment, the patient vomited severely and reported severe right upper abdominal pain. He was diagnosed with DH, and surgical fixation was performed. The diaphragmatic injury lesion was located on the estimated needle track of percutaneous radiofrequency ablation, which was performed through the thoracic diaphragm with artificial pleural effusion for hepatocellular carcinoma.
