RESUMEN
BACKGROUND & AIMS: In the global, phase III HIMALAYA study in unresectable hepatocellular carcinoma (uHCC), STRIDE (Single Tremelimumab Regular Interval Durvalumab) improved overall survival (OS) vs. sorafenib; durvalumab was noninferior to sorafenib. HBV is the predominant HCC aetiology in most of Asia vs. HCV or nonviral aetiologies in Western countries and Japan. This analysis evaluated safety and efficacy outcomes for STRIDE and durvalumab monotherapy vs. sorafenib, in HIMALAYA participants enrolled in Asia, excluding Japan. METHODS: In HIMALAYA, participants were randomised to STRIDE, durvalumab, or sorafenib. The Asian subgroup in this analysis included participants enrolled in Hong Kong, India, South Korea, Taiwan, Thailand, and Vietnam. OS, objective response rate (ORR; per Response Evaluation Criteria in Solid Tumors, version 1.1), and safety were assessed in the Asian subgroup and in an exploratory subgroup of participants in Hong Kong and Taiwan. RESULTS: The Asian subgroup included 479 participants randomised to STRIDE (n=156), durvalumab (n=167), or sorafenib (n=156). OS was improved for STRIDE vs. sorafenib (HR 0.68; 95% CI 0.52-0.89]). The OS HR for durvalumab vs. sorafenib was 0.83 (95% CI 0.64-1.06). In Hong Kong and Taiwan (n=141), OS HRs for STRIDE vs. sorafenib and durvalumab vs. sorafenib were 0.44 (95% CI 0.26-0.77) and 0.64 (95% CI 0.37-1.08), respectively. In the Asian subgroup, ORR (including unconfirmed responses) was numerically higher for STRIDE (28.2%) and durvalumab (18.6%) vs. sorafenib (9.0%), and Grade 3/4 treatment-related adverse events were numerically lower for STRIDE (19.9%) and durvalumab (13.3%) vs. sorafenib (30.5%). CONCLUSIONS: STRIDE improved outcomes vs. sorafenib in the Asian subgroup. These results support the benefits of STRIDE for participants with uHCC globally, including the Asia-Pacific region. CLINICAL TRIAL NUMBER: NCT03298451 IMPACT AND IMPLICATIONS: The global, phase III HIMALAYA study found that the STRIDE (Single Tremelimumab Regular Interval Durvalumab) regimen improved overall survival (OS), including long-term OS, vs. sorafenib, and that durvalumab monotherapy was noninferior to sorafenib in participants with unresectable hepatocellular carcinoma (uHCC). However, there are differences in the aetiology and clinical practices related to HCC in parts of Asia, compared to Western countries and Japan, which could lead to differences in treatment outcomes between these regions. The results of this analysis demonstrate the benefits of STRIDE for participants in the Asia-Pacific region, consistent with the full, global study population. Overall, these findings continue to support the use of STRIDE in a diverse population, reflective of uHCC globally.
RESUMEN
This study aimed to complement the results of the REACH-2 study by prospectively evaluating the safety and efficacy of ramucirumab in advanced hepatocellular carcinoma (HCC) in a real-world setting. This was an open-label, nonrandomized, multicenter, prospective study conducted at 13 institutions in Japan (jRCTs031190236). The study included Child-Pugh Class A patients with advanced HCC who had received pretreatment with atezolizumab plus bevacizumab (Atez/Bev) or lenvatinib. Ramucirumab was introduced as a second-line treatment after Atez/Bev or lenvatinib and as a third-line treatment after Atez/Bev and lenvatinib. Between May 2020 and July 2022, we enrolled 19 patients, including 17 who received ramucirumab. Additionally, seven patients received lenvatinib, another seven patients received Atez/Bev, and three patients received Atez/Bev followed by lenvatinib as prior treatment. The primary endpoint was a 6-month progression-free survival (PFS) rate, which was 14.3%. The median PFS and overall survival were 3.7 and 12.0 months, respectively. The most common grade ≥ 3 adverse events (AEs) were hypertension (23.5%), proteinuria (17.6%), and neutropenia (11.8%). The discontinuation rate due to AEs was 29.4%. Six patients progressed from Child-Pugh A to B after treatment with ramucirumab. Thirteen patients were eligible for post-ramucirumab treatment, including systemic therapy. Despite the limited number of patients, the efficacy of ramucirumab was comparable to that observed in the REACH-2 study when used after lenvatinib and Atez/Bev. However, the incidence of AEs was higher than that in the REACH-2 study.

INTRODUCTION: Systemic therapy is recommended for patients with Child-Pugh A in hepatocellular carcinoma (HCC). We analyzed the outcomes of a cohort of patients with HCC who received either sorafenib (Sor), lenvatinib (Len) or atezolizumab plus bevacizumab (Atezo + Bev) as first-line systemic therapy for HCC, with the aim of identifying prognostic factors for survival. METHODS: A total of 825 patients with advanced HCC and Child-Pugh A or B received either Sor, Len or Atezo + Bev as first-line systemic therapy. Liver function was assessed according to the Child-Pugh score and the modified albumin-bilirubin (mALBI) grade. RESULTS: Prognosis was analyzed according to liver function such as Child-Pugh classifications, scores, and mALBI grades that worsened with a decline in liver function (p <0.001 for all). A Child-Pugh score of 7 was a factor significantly associated with OS. In patients with a Child-Pugh score of 7, an mALBI grade of 3 was an independent predictor of OS. In Child-Pugh B patients with HCC, receiving Atezo + Bev was identified as a factor associated with PFS. CONCLUSION: Determining the hepatic reserve of patients with unresectable HCC might be useful for identifying patents suitable for systemic treatment for HCC. Atezo + Bev might prolong the PFS of patients with a Child-Pugh score of 7.

AIM: Autotaxin (ATX) is a newly identified liver fibrosis biomarker; however, its clinical usefulness remains unclear. Therefore, we analyzed the changes in patients with chronic hepatitis B virus infection treated with nucleos(t)ide analogs (NAs) to evaluate its usefulness. We also investigated the predictors of hepatocellular carcinoma development, including ATX, in patients with chronic hepatitis B based on their clinical characteristics. METHODS: This retrospective study included 179 patients with hepatitis B virus infection treated with NAs for >2 years. First, we measured the ATX levels before and up to 10 years after initiating entecavir (therapy for 88 patients whose serial ATX levels could be measured before and during entecavir therapy. Subsequently, for 179 patients whose ATX levels could be measured at the commencement of NAs, we examined the factors involved in developing hepatocellular carcinoma, including ATX. RESULTS: The ATX levels showed a gradual and significant decrease during the observation period of up to 10 years. Multivariable analysis showed that a baseline ATX/upper limits of normal ratio ≥1.214, age, and alkaline phosphatase levels were independent risk factors for hepatocellular carcinoma development. The combination of age and ATX/upper limits of normal ratio was used to stratify the high-risk groups for liver carcinogenesis. CONCLUSIONS: A decrease in ATX levels up to 10 years after the commencement of therapy suggested that ATX is a helpful biomarker in evaluating fibrosis in patients undergoing long-term NA therapy. Furthermore, this study showed that combining age and the baseline ATX/upper limits of normal ratio may help identify high-risk carcinogenesis groups.
RESUMEN
AIM: A nationwide survey in 2018 showed decreasing involvement of viral hepatitis and increasing involvement of nonviral liver diseases in the etiology of liver cirrhosis (LC) in Japan. An updated nationwide survey was undertaken in 2023. METHODS: Cases of LC diagnosed between 2018 and 2021 were collected from 75 institutions, and the etiologies of LC were investigated. In addition, the data obtained were compared with the results of previous studies. RESULTS: Among the 15 517 cases, alcohol-related liver disease (ALD)-associated LC was the most frequent cause (n = 5,487, 35.4%). Hepatitis C virus-associated LC, nonalcoholic steatohepatitis (NASH)-associated LC, and hepatitis B virus-associated LC were ranked as second, third, and fourth, respectively. In comparison to the previous survey, the ratios of viral hepatitis-associated LC decreased (HBV: from 11.5% to 8.1%; HCV: from 48.2% to 23.4%), while the ratios of ALD-associated LC and NASH-associated LC increased (from 19.9% to 35.4% and from 6.3% to 14.6%, respectively). Regarding cases of LC with hepatocellular carcinoma (n = 5906), HCV-associated LC (1986 cases, 33.6%) was the most frequent cause. Alcohol-related liver disease-associated LC, NASH-associated LC, and HBV-associated LC were the second-, third-, and fourth-ranked causes, respectively. In comparison to the previous survey, as the cause of hepatocellular carcinoma-complicated LC, HCV-associated LC decreased from 60.3% to 33.6%, while the ratios of ALD-associated LC and NASH-associated LC increased from 14.2% to 28.6% and from 4.2% to 14.0%, respectively. CONCLUSIONS: The major causes of LC in Japan are suggested to have been shifting from viral hepatitis to nonviral chronic liver diseases.
RESUMEN
AIM: When evaluating response to immune checkpoint inhibitor therapy, the tumor sometimes initially swells before shrinking and ultimately responding, also called pseudo-progression. In this study, we analyzed whether tumor markers were useful for reflecting the treatment response. METHODS: Thirty-three patients who were treated with durvalumab plus tremelimumab combination therapy (Dur + Tre) were enrolled. Their functional reserve was Child-Pugh grade A. Their tumor markers α-fetoprotein (AFP), des-γ-carboxy prothrombin (DCP), or AFP-Lectin 3 fraction (AFP-L3) were positive. Tumor markers were evaluated before treatment and at 1, 4, and 8 weeks after the start of treatment. The first radiological evaluation was carried out at 4 weeks and the second evaluation at 8-12 weeks. The responders included those with complete response and partial response and the nonresponders included those with stable disease (SD) and progression disease at best response evaluated by Response Evaluation Criteria in Solid Tumors. RESULTS: In the responder group, the change ratio of AFP, DCP, and AFP-L3 specifically decreased at 8 weeks. In the nonresponder group, the change ratio of DCP specifically increased at 4 weeks. The optimal cut-off value to divide responders and nonresponders at 4 weeks was approximately -40%. The ratio of responders was 72.7% in the patients whose AFP or DCP decreased over 40% at 4 weeks. CONCLUSIONS: The change in tumor markers is a more useful predicter of tumor response to Dur + Tre than imaging evaluation alone.
RESUMEN
AIM: Shear wave (SW) elastography is used to evaluate metabolic dysfunction-associated steatotic liver disease (MASLD) pathophysiology. Increased elasticity due to fibrosis and increased viscosity due to necrosis and inflammation affect SW. Assessing fibrosis, the most prognostically relevant pathology, is critical. Viscosity is evaluated using the dispersion slope (DS); however, cut-off values that affect SW values are unclear. We compared the ultrasound imaging parameters (SW for viscoelasticity; DS for viscosity) with pathological findings. METHODS: Patients (n = 159) who underwent liver biopsy and SW and DS assessments at our hospital were included. Fibrosis stage and inflammation grade cut-off values were calculated from SW, DS, and liver biopsy results using receiver operating characteristic curves. Cases in which liver biopsy results were inconsistent with SW results were used to determine the effect of viscosity on SW values. DS was examined in the Correct and Incorrect Diagnosis groups, which were categorized based on the concordance between SW and liver biopsy results. Dispersion slope cut-off values between the two groups were calculated. RESULTS: Fibrosis stage cut-off values by SW (m/s) were: ≥F2, 1.62; ≥F3, 1.74; and F4, 1.97. Inflammation grade cut-off values by DS (m/s/kHz) were: ≥A1, 11.6; ≥A2, 14.5; and A3, 16.1. The Correct/Incorrect Diagnosis groups had 25/70 patients. The DS cut-off value for both groups was 13.2 m/s/kHz. CONCLUSIONS: Shear wave and DS are useful for evaluating liver fibrosis and inflammation in MASLD. For DS > 13.2 m/s/kHz, SW may be affected by the increased viscosity owing to inflammation. In such patients, caution should be used when determining/interpreting values.
RESUMEN
BACKGROUND: Hepatitis B virus (HBV) evades host immunity by regulating intracellular signals. To clarify this immune tolerance mechanism, we performed gene expression analysis using HBV-infected humanized mouse livers. METHODS: Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) receptor 3 (TRAIL-R3) was significantly upregulated in livers of HBV-infected human hepatocyte transplanted mice by cDNA microarray and next-generation sequencing. We analyzed the significance of TRAIL-R3 upregulation in HBV infection using human hepatocyte transplanted mice and HepG2 cell lines. RESULTS: TRAIL-R3 induction by HBV infection was verified by in vitro and in vivo HBV replication models, and induction was inhibited by antiviral nucleot(s)ide analogue treatment. TRAIL-R3 transcription was regulated by the TRAIL-R3 promoter at -969 to -479 nucleotides upstream from the transcription start site, and by hepatitis B x (HBx) via activation of nuclear factor-κB (NF-κB) signal. TRAIL not only induced cell apoptosis but also inhibited HBV replication. TRAIL-R3 upregulation could inhibit both TRAIL-dependent apoptosis in HBV-infected hepatocytes and TRAIL-mediated suppression of HBV replication. CONCLUSIONS: These results suggest a mechanism by which HBV persists by escaping host immunity through upregulation of TRAIL-R3. Development of novel drugs to inhibit this escape system might lead to complete HBV elimination from human hepatocytes.

INTRODUCTION: Measurements of body composition, such as the skeletal muscle index (SMI), are useful for predicting prognosis in hepatocellular carcinoma (HCC). This study aimed to analyze the relationship between skeletal muscle changes during therapy with atezolizumab plus bevacizumab (Atezo + Beva) or lenvatinib (Len) and the association between SMI and prognosis. METHODS: Patients with advanced HCC and Child-Pugh A status received Atezo + Beva or Len as first-line systemic chemotherapy. We assessed prognosis and body composition obtained by bioelectrical impedance analysis. RESULTS: A total of 109 patients received treatment (Atezo + Beva, n = 47; Len, n = 62). During treatment, the arm SMI was reduced in the Len group and maintained in the Atezo + Beva group. The extracellular water to total body water ratio (ECW/TBW) increased significantly in both groups during treatment. In the Atezo + Beva group, no factor was associated with prognosis. Multivariate analysis showed that in the Len group, the arm SMI (hazard ratio [HR], 0.5; 95% CI: 0.26-0.89; p = 0.02), ECW/TBW (HR: 2.7; 95% CI: 1.21-6.01; p = 0.01), and Child-Pugh score (HR: 2.3; 95% CI: 1.31-6.13; p = 0.004) were associated with progression-free survival. CONCLUSION: Assessing body composition with BIA before Atezo + Beva and Len treatment may be useful.

BACKGROUND: Metabolic dysfunction-associated fatty liver disease (MAFLD) represents a new classification system for fatty liver disease. In this study, we investigated the clinical characteristics of patients with MAFLD-hepatocellular carcinoma (HCC) in comparison with those with nonalcoholic fatty liver disease (NAFLD) and considered the validity and challenges of the new criteria. METHODS: This study included 237 untreated non-B, non-C HCC patients with hepatic steatosis. We examined the profile and laboratory findings of patients with MAFLD-HCC and NAFLD-HCC. We also classified MAFLD-HCC patients according to the factors on which the diagnosis was based and compared their clinical characteristics. RESULTS: A total of 222 (94%) and 101 (43%) patients were diagnosed with MAFLD and NAFLD, respectively. MAFLD-HCC patients were more likely to be male than NAFLD-HCC, but there were no significant differences in metabolic indices, noninvasive liver fibrosis score or HCC status. In a study of MAFLD-HCC patients by diagnostic factor, those with overweight only were younger and had advanced liver fibrosis histologically, and when limited to patients younger than 70 years, the majority were overweight. Redefinition of overweight as BMI ≥ 25 reduced the number of MAFLD-HCC patients by only 5, from 222 to 217. CONCLUSIONS: MAFLD accounted for the majority of non-B, non-C HCC cases with hepatic steatosis. Examination of additional cases and revision of the detailed criteria is needed so that it can be used to efficiently select patients with fatty liver who are at high risk of developing HCC.

BACKGROUND AND AIM: The prognosis of acute liver failure (ALF) remains poor, and liver transplantation is an alternative treatment option. Assessing the prognosis of ALF is important in determining treatment strategies. Here, we investigated clinical factors including serum pro-inflammatory cytokine levels that are associated with the prognosis of ALF. METHODS: Sixty-six patients who developed ALF were enrolled in this study. Serum concentrations of 12 pro-inflammatory cytokines were measured on admission. The prognosis and factors associated with survival and development of hepatic coma were analyzed. RESULTS: Of 66 patients, 4 patients underwent liver transplantation, and 49 patients were rescued without liver transplantation, while the remaining 13 patients died. Serum concentrations of interleukin (IL)-1ß, IL-4, IL-6, IL-8, IL-13, TNF, IFN -γ, IP-10, and G-CSF were significantly elevated in ALF patients. IL-4 and IL-8 levels were higher in patients who underwent liver transplantation or died than in rescued patients. Multivariable analysis identified age ≥ 55 years and IL-4 ≥ 1.2 pg/mL on admission as independent factors for mortality. Serum IL-8 levels were higher in patients with hepatic coma, and prothrombin-international normalized ratio ≥ 3.5 and IL-8 ≥ 77.2 pg/mL on admission were associated with development of hepatic coma after admission. CONCLUSION: Serum levels of several pro-inflammatory cytokines were elevated in ALF patients. IL-4 and IL-8 were correlated with survival and development of hepatic coma after admission, respectively. Measurement of serum pro-inflammatory cytokines seems to be useful for the management of ALF.

Recently, a distinct vascular pattern in hepatocellular carcinoma (HCC) called vessels encapsulating tumor-forming clusters (VETC) has received attention because of its association with poor prognosis. However, little is known about the mechanism by which VETC promotes an aggressive phenotype at the molecular level. In our study, the association between differences in stepwise signal intensity in the HB phase and molecular subtypes and somatic mutations associated with the immune microenvironment were investigated using the International Cancer Genome Consortium (ICGC) cohort (66 patients). To our knowledge, this is the first study to analyze the molecular patterns of VETC using RNA-Seq data. The VETC+ HCC group showed significantly lower overall survival and higher cumulative incidence of extrahepatic metastasis after curative hepatic resection than the VETC- HCC group. The VETC+ group exhibited molecular features indicative of lower immune activation than the VETC- group, suggesting that tumor cells in the VETC+ group were more likely to escape from the immune response, which could lead to the shorter OS (Overall survival) and higher risk of metastasis. On the other hand, gene expression levels of fibroblast growth factor receptors were upregulated in VETC+ HCC, suggesting that VETC+ HCC might benefit from lenvatinib treatment. Our results demonstrate that VETC+ HCC was associated with the suppression of tumor immune responses at the molecular level.

BACKGROUND: Balloon-occluded retrograde transvenous obliteration (BRTO) is a treatment option for patients with gastric varices (GVs). This study aimed to clarify the clinical significance of portal hypertension estimated by the hepatic venous pressure gradient (HVPG), subsequent exacerbation of esophageal varices (EVs), and prognosis of patients who underwent BRTO for GVs. METHODS: Thirty-six patients with GVs treated with BRTO were enrolled in this study, and their HVPG was measured before (pre-HVPG) and on the day after BRTO (post-HVPG). After BRTO, patients were followed-up for a median interval of 24.5 (3-140) months. Clinical factors related to EVs exacerbation and prognosis after BRTO were retrospectively analyzed. RESULTS: Post-HVPG increased compared to pre-HVPG in 21 out of 36 patients (58%), and post-HVPG was overall significantly higher compared to pre-HVPG (P = 0.009). During the observation period, 19 patients (53%) developed EVs exacerbation, and the cumulative EVs exacerbation rates at 1, 3 and 5 years after BRTO were 27%, 67%, and 73%, respectively. Pre-HVPG was not related to EVs exacerbation, although elevation of post-HVPG to ≥ 13 mmHg (P < 0.01) and high level of serum aspartate aminotransferase (P < 0.05) were significant independent risk factors for EVs exacerbation after BRTO. Fourteen patients (38.9%) died during the observation period. An elevated value of liver stiffness measurement (LSM) of ≥ 21 kPa was a significant independent risk factor for poor prognosis after BRTO (P < 0.05). CONCLUSIONS: HVPG increases after BRTO. HVPG after BRTO has greater predictive ability for subsequent EVs exacerbation than HVPG before BRTO. LSM is a potential prognostic parameter in patients who undergo BRTO.

BACKGROUND: Patients with hepatocellular carcinoma (HCC) and macrovascular invasion (MVI) who receive systemic chemotherapy have a poor prognosis. This study aimed to determine if one-shot cisplatin (CDDP) chemotherapy via hepatic arterial infusion (HAI) combined with radiation therapy (RT) prior to systemic chemotherapy could improve the outcomes of these patients. METHODS: This study consisted of 32 HCC patients with the following eligibility criteria: (i) portal vein invasion 3/4 and/or hepatic vein invasion 2/3; (ii) received one-shot CDDP via HAI; (iii) received RT for MVI, (iv) a Child-Pugh score ≤ 7; and (v) an Eastern Clinical Oncology Group Performance Status score of 0 or 1. To determine the therapeutic effect, we collected information on patient characteristics and took contrast-enhanced computed tomography at the start of the therapy and every 2 to 4 months after the start of therapy. We evaluated the overall response of the tumor and tumor thrombosis according to modified Response Evaluation Criteria in Solid Tumors. We assessed patient data using the Mann-Whitney U and Fisher exact tests and evaluated overall survival and progression-free survival using the log-rank test. RESULTS: The overall response rate at the first evaluation performed a median of 1.4 weeks after HAI was 16% for the main intrahepatic tumor and 59% for the MVI. The best responses were the same as those of the first-time responses. The duration of median survival was 8.6 months, and progression-free survival of the main intrahepatic tumor was 3.2 months. Predictive factors for overall survival were the relative tumor volume in the liver and the first therapeutic response of MVI. There were no severe adverse events or radiation-induced hepatic complications. CONCLUSIONS: One-shot CDDP via HAI and RT were well tolerated and showed immediate and favorable control of MVI. Thus, this combination shows potential as a bridging therapy to systemic chemotherapy.

BACKGROUND AND AIM: The prevalence of glucose intolerance in chronic liver disease patients is high, but glucose intolerance may be overlooked in a single blood test. The purpose of this study is to evaluate blood glucose variability in patients with chronic liver disease by a continuous glucose monitoring system (CGMS) and to examine the discrepancy between hemoglobin A1c (HbA1c) levels estimated from average blood glucose levels and HbA1c. METHODS: This study included 335 patients with chronic liver disease associated with glucose intolerance. A fasting blood test and 72-h CGMS were performed. The estimated HbA1c was calculated from the average blood glucose level, and the correlation between hepatic functional reserve and blood glucose-related parameters was analyzed. From the obtained data, we created a new formula to calculate HbA1c without using CGMS. RESULTS: As hepatic functional reserve decreased, average blood glucose and insulin resistance increased while HbA1c decreased (P < 0.0001). The discrepancy between the estimated HbA1c calculated from the mean blood glucose level and the serum HbA1c (ΔHbA1c) increased as the liver reserve decreased. Using multiple regression analysis, a formula based on fasting blood glucose, HbA1c, body mass index, albumin, and liver function was constructed, and its validity was demonstrated in a study using a different control group. CONCLUSIONS: Hemoglobin A1c may be underestimated because of decreased hepatic functional reserve. CGMS was useful in assessing accurate glycemic control of blood glucose and in detecting postprandial hyperglycemia and nocturnal hypoglycemia. Patients with chronic hepatic impairment should be corrected for hepatic functional reserve before glycemic control.

Combination therapy with glecaprevir and pibrentasvir (PIB) has high efficacy for patients with hepatitis C virus (HCV) infection except among those who experienced NS5A-P32 deletion (del) mutation during prior DAA treatment failure. However, some patients fail to achieve SVR through combination treatment even in the absence of NS5A-P32del. We analyzed emergence of NS5A resistance-associated substitutions (RASs) against PIB using HCV-infected mice. Male human hepatocyte transplanted mice were infected with genotype 1b wild-type HCV. Mice were treated with PIB, resulting in a transient decrease in serum HCV RNA levels but followed by relapse during the treatment. Direct sequence analysis showed emergences of various mutations in the NS5A region, including L31V/P32del, L31F/P32del/Y93H, NS5A-P29del/Y85C, and NS5A-F37Y. PIB was less effective in mice with NS5A-F37Y mutations compared to mice with wild-type HCV. NS5A-F37Y showed 5.4-fold resistance to PIB relative to wild-type based on analysis using HCV subgenomic replicon systems. The present in vivo and in vitro studies identified NS5A-F37Y as a novel RAS against PIB and showed the possibility of emergence of various NS5A RASs including P29del, P32del and F37Y following PIB treatment. These mutations might emerge and lead to failure to respond to DAA therapies including PIB-based regimens in chronic hepatitis C patients.

While the preS1 region of the large hepatitis B surface protein plays an essential role in hepatitis B virus (HBV) infection, the effect of preS1 on liver fibrosis and hepatocarcinogenesis in chronic hepatitis B (CHB) patients is not well known. In this study, we measured serum preS1 levels by chemiluminescent immunoassay technology in 690 CHB patients and evaluated the correlation between serum preS1 levels and HBV, liver function markers and liver inflammation, fibrosis assessed by histological findings. Predictive factors for hepatocellular carcinoma (HCC) development in patients who had no previous history of HCC at the time of preS1 level measurement were also analysed. Median hepatitis B surface antigen (HBsAg) and preS1 levels were 3.08 log IU/mL and 98 ng/mL, respectively. PreS1 values were significantly correlated with serum HBsAg (p <0.001), hepatitis B core-related antigen (HBcrAg) (p <0.001) and HBV DNA levels (p <0.01). PreS1 values were also significantly correlated with serum alanine aminotransferase levels (p <0.001) and were significantly higher in patients who had higher grading of liver inflammatory activity (p <0.05). HBsAg level was correlated, but preS1/HBsAg ratio reflected liver fibrosis staging more directly than HBsAg alone. Multivariate analysis identified age ≥53 years (hazard ratio [HR], 18.360 for <53 years; p = 0.021) and preS1/HBsAg ratio ≥0.12 (HR, 6.205 for <0.12; p = 0.040) as significant and independent factors for HCC development in CHB patients. The preS1/HBsAg ratio directly reflects liver fibrosis, and the ratio might be a predictive marker for HCC development in CHB patients.

Although glucocorticoids have been used for immunosuppression of patients with primary hepatitis B virus (HBV) infection-induced severe hepatitis, the treatment is associated with a high frequency of adverse events. We conducted a pilot study for evaluating the efficacy and safety of abatacept, a cytotoxic T lymphocyte antigen-4 immunoglobulin (CTLA4), for acute hepatitis B. Five patients with severe acute hepatitis B (prothrombin activity ≤ 60%) were treated for immunosuppression by abatacept. Four patients received abatacept concurrently with methylprednisolone, and another patient was treated with abatacept alone. Rapid decrease in serum alanine aminotransferase levels, increase in prothrombin activity and improvement of general condition were obtained in four out of five patients. The patient with the most severe hepatitis underwent liver transplantation due to exacerbation of hepatitis in spite of treatment with both abatacept and methylprednisolone. None of the patients developed significant adverse events associated with the use of abatacept. Hepatitis B surface antigen (HBsAg) became negative in all five patients. The effect of abatacept and methylprednisolone for severe hepatitis B was compared using a mouse model. Rapid reduction in mouse serum HBV DNA and human albumin levels and elevation of serum interferon-gamma and granzyme A levels were observed in HBV-infected human hepatocyte-transplanted immunodeficient mice that were administered human peripheral blood mononuclear cells. These hepatocyte injuries were inhibited to a greater extent by abatacept compared to methylprednisolone. Abatacept might be an effective therapy alternative to methylprednisolone to reduce acute massive liver damage for patients with severe acute hepatitis caused by HBV infection.

INTRODUCTION: We evaluated the efficacy and safety of lenvatinib-transcatheter arterial chemoembolization (LEN-TACE) sequential therapy for patients (n = 88) with intermediate-stage hepatocellular carcinoma (HCC). METHODS: Eighty-eight patients who obtained tumor control by LEN treatment were analyzed; 30 received LEN followed by TACE (LEN-TACE sequential therapy), and 58 received LEN monotherapy. Propensity score matching was performed, and the outcomes of 19 patients in the LEN-TACE group and 19 patients in the LEN-alone group were compared. Objective response rate (ORR), progression-free survival (PFS), overall survival (OS), incidence of adverse events (AEs), and change in albumin-bilirubin (ALBI) score were evaluated. RESULTS: After matching, baseline characteristics were similar between the groups. The ORR was 63.2% with LEN-TACE group and 63.2% with the LEN-alone group. Multivariate analysis showed that addition of TACE during LEN treatment (hazard ratio [HR] 0.264, 95% confidence interval [CI] 0.087-0.802, p = 0.019) and Child-Pugh score 5 (HR 0.223, 95% CI 0.070-0.704, p = 0.011) were the significant factors for PFS. Median PFS was 11.6 months with LEN-TACE and 10.1 months with LEN-alone. The survival rate of the LEN-TACE group was significantly higher than that of the LEN-alone group (median survival time; not reached vs. 16.9 months, p = 0.007). The incidence of common LEN-associated AEs was similar between groups. Although elevated aspartate aminotransferase/alanine aminotransferase and fever were more frequent with LEN-TACE group, these events were manageable. CONCLUSION: For patients with intermediate-stage HCC, LEN-TACE sequential therapy may provide a deep response and favorable prognosis.

INTRODUCTION: The clinical outcome of ramucirumab in multi-molecular targeted agent (MTA) sequential therapy for unresectable hepatocellular carcinoma (u-HCC) was assessed in comparison with that of prior tyrosine kinase inhibitor (TKI) therapy. METHODS: Sixteen patients who received ramucirumab as part of multi-MTA sequential therapy for u-HCC were enrolled in a retrospective, cohort study. Ramucirumab was started as 2nd line in 7 patients, 3rd line in 5 patients, and 4th line in 4 patients. RESULTS: The overall response rate was 6.3%, the disease control rate (DCR) was 50.0%, median progression-free survival was 2.0 months (evaluated by mRECIST), median overall survival (OS) with ramucirumab was 7.9 months, and the median OS from 1st-line therapy was 28.1 months. One month after the start of ramucirumab, α-fetoprotein (AFP) decreased in 6 of 12 cases (50.0%), and the DCR in AFP-decreased cases was 83.3%. The DCR of ramucirumab was 66.7% in cases in which disease control was obtained by prior TKI therapy, whereas it was 0.0% in the cases in which disease control was not obtained by prior TKI therapy. Examining the adverse events, no new safety concerns were confirmed. CONCLUSION: The AFP response to ramucirumab and the treatment response to prior TKI therapy are associated with treatment response to ramucirumab.
