AimThis study aimed to determine the efficacy and safety of lenvatinib for patients with unresectable hepatocellular carcinoma (HCC) who did not meet REFLECT eligibility criteria (phase 3 clinical trial).MethodsIn this multicenter retrospective study, patients with unresectable HCC treated with lenvatinib between 2018 and 2019 and had adequate clinical data were included. Objective response rate, progression‐free‐survival (PFS) and safety were evaluated according to meeting or not meeting the REFLECT eligibility criteria and according to the criteria of the REFLECT trial.ResultsOf the 105 patients included, 61% (64 of 105) did not meet the REFLECT eligibility criteria. Safety and median PFS of lenvatinib were similar between the patients who did and those who did not meet the criteria. Among the patients who did not meet the criteria, 28, 27, 14, six, seven and five had a history of tyrosine kinase inhibitor (TKI) treatment, Child–Pugh score B, HCC in ≥50% of the liver, reduced platelet count, bile duct invasion and main portal vein invasion, respectively. The efficacy and safety of lenvatinib for patients with or without Child–Pugh‐score B or HCC in ≥50% of the liver were similar. Although treatment outcome was not significantly different, patients with TKI treatment history tended to have longer median PFS, whereas those with main portal vein invasion tended to have shorter median PFS.ConclusionLenvatinib was effective for patients who did not meet the REFLECT inclusion criteria. However, the treatment outcome may vary according to several factors, such as a history of TKI treatment and tumor invasion.
Background and Aim Lenvatinib has been recently approved as a first‐line systematic therapy for patients with advanced hepatocellular carcinoma (HCC) based on the results of the phase 3 clinical trial REFLECT. This trial excluded patients with a history of systemic chemotherapy, bile duct invasion, and Child‐Pugh grade B. We aimed to investigate the efficacy and safety of lenvatinib for these patients and in the real‐world setting. Methods Among patients who were administered lenvatinib for advanced HCC between April and October 2018 in Hokkaido University Hospital and related hospitals, we evaluated those who were followed for more than 2 months and whose treatment response was evaluated via dynamic computed tomography at baseline and 2 months after treatment initiation. Meanwhile, patients were excluded if they had decompensated liver cirrhosis, were followed up less than 2 months, or were not evaluated at 2 months. Patients were also stratified according to compliance with the REFLECT inclusion criteria for further analysis. Results A total of 41 patients were included; more than 50% did not meet the REFLECT inclusion criteria. In total, 5 (12.2%), 20 (48.8%), 12 (29.3%), and 4 (9.3%) showed complete response, partial response, stable disease, and progressive disease, respectively. The objective response rate was 61.2%. The objective response rate and disease control rate were similar between patients who did and did not meet the REFLECT inclusion criteria. Moreover, the safety profile was also similar between the two patient groups. Conclusion Lenvatinib showed high early response rate and tolerability in patients with advanced HCC. Favorable outcomes were similarly observed in patients who did not meet the REFLECT inclusion criteria.
Aim Factors associated with improvement of liver fibrosis after successful hepatitis C virus (HCV) eradication by interferon (IFN)‐free direct‐acting antiviral agents (DAAs) have been not clarified well. Angiopoietin‐2 (Ang2) is reported to be associated with vascular leak and inflammation observed in patients with advanced liver fibrosis. Methods In this retrospective study, patients treated with IFN‐free DAAs who underwent transient elastography before and at 24‐weeks post‐treatment and achieved sustained viral response were enrolled. Baseline serum Ang2 was measured, and its relationship with other clinical factors was analyzed. Liver fibrosis stage was defined based on liver stiffness according to a previous report. Predictive factors for regression of liver fibrosis stage after DAA therapy were evaluated. Results Overall, 116 patients were analyzed. Baseline serum Ang2 levels were significantly associated with liver stiffness, spleen index, and liver stiffness‐based liver fibrosis stage. Moreover, 75% of patients experienced regression of liver fibrosis stage after DAA therapy. Multivariate analysis revealed that advanced liver fibrosis stage and Ang2 levels were significantly associated with regression of liver fibrosis stage after DAA therapy. In patients with advanced liver fibrosis (F3/4), baseline Ang2 level alone could predict regression of liver fibrosis stage. A baseline Ang2 cut‐off value (354 pg/ML) could predict regression of liver fibrosis stage after DAA therapy with high accuracy (sensitivity 0.882, specificity 0.733). Conclusions Evaluation of serum Ang2 levels before DAA therapy is important. Our results provide a novel mechanistic insight into non‐regression of liver stiffness after DAA therapy. Long‐term and larger studies are required.
Aim This study aimed to determine the optimal psoas muscle mass index (PMI) cut‐off values for diagnosis of skeletal muscle mass loss. Methods We evaluated PMI in two groups of normal controls: a medical check‐up group and a liver donation candidate group. We analyzed two novel PMI cut‐off values, one based on the mean – two standard deviations (2SD) and one based on the lower 5%. Skeletal muscle mass index (SMI) evaluations using computed tomography (sliceOmatic; TomoVision) and bioelectrical impedance analysis and PMI evaluation were undertaken simultaneously. We analyzed the correlation between our PMI cut‐off values and the Japan Society of Hepatology‐defined SMI cut‐off values. The prevalence of skeletal muscle mass loss in patients with liver disease was assessed using the novel PMI cut‐off values. Results In 504 normal controls aged ≤50 years, the PMI cut‐off values based on mean –2SD and the lower 5% were set at 3.30 cm2/m2 for men and 1.69 cm2/m2 for women and 3.74 cm2/m2 for men and 2.29 cm2/m2 for women, respectively. The PMI cut‐off values based on the lower 5% alone showed that skeletal muscle mass loss increased with age. Furthermore, they correlated well with Japan Society of Hepatology‐defined SMI (sliceOmatic) cut‐off values and showed a significantly higher prevalence of skeletal muscle mass loss in patients with liver cirrhosis than those without liver cirrhosis. Conclusions We propose the following PMI cut‐off values: 3.74 cm2/m2 for male individuals and 2.29 cm2/m2 for female individuals. These cut‐off values can facilitate accurate diagnosis and management of sarcopenia in patients with chronic liver disease.
Background: The cold polypectomy (CP) technique has been increasingly used in recent years. However, there have been few studies about post-polypectomy bleeding (PPB) in patients who underwent CP and who were on antithrombotic drugs. The objective of this study was to determine the safety of CP in patients on antithrombotic medication. Methods: The subjects were patients who underwent CP in our hospital between April 2014 and March 2016. PPB rates were examined in relation to the use of antithrombotic medication. Results: CP was performed to remove 2,466 polyps in 1,003 patients. There were 549 polyps (22.3%) in186 patients in the antithrombotic group and 1,917 polyps (77.7%) in 817 patients in the non-antithrombotic group. PPB occurred in 0.55% (3/549) of patients in the antithrombotic group and in 0.10% (2/1,917) of patients in the non-antithrombotic group, showing no significant difference (p = 0.07). Patients in the antithrombotic group in whom PPB occurred included 1 aspirin user with 1 polyp and 1 aspirin plus clopidogrel user with 2 polyps. No PPB occurred in patients on other antithrombotic agents or receiving heparin bridging. There was no significant difference between PPB rates in patients with small polyps (6–9 mm) in the antithrombotic and non-antithrombotic groups, but there was a significant difference between PPB rates in the 2 groups for patients with diminutive group (1–5 mm). Conclusion: CP is a safe procedure even in patients on antithrombotic medication.
Aim Entecavir (ETV), tenofovir disoproxil fumarate (TDF), and tenofovir alafenamide (TAF) are first‐line nucleos(t)ide analogues for hepatitis B virus (HBV)‐infected patients. However, consecutive TDF treatment causes renal dysfunction, and the safety and efficacy of TAF have not been established in severe renal dysfunction patients, including hemodialysis patients. The efficacy and safety of ETV in these populations has not been clarified. The study aimed to clarify this. Methods In this retrospective multicenter study, between 2006 and 2018, a total of 567 HBV‐infected patients treated with ETV monotherapy were screened. Patients were included if >20 years old, treated with ETV monotherapy for >1 year, and had proper clinical information. The efficacy of ETV and changes in renal function were evaluated according to renal function. Results A total of 273 patients were included: 9.2% (25/273), 1.8% (5/273), and 3.7% (10/273) had chronic kidney disease (CKD) stage G3, CKD stage G4/5, and were on hemodialysis, respectively. Overall, 84.2%, 94.0%, and 96.2% of patients experienced serum HBV‐DNA disappearance at 1, 2, and 3 years, respectively, after treatment initiation. In patients with CKD stage G3–5, estimated glomerular filtration rate tended to restore with time, which was in contrast to patients without renal dysfunction. The rate of disappearance in serum HBV‐DNA, alanine transaminase normalization, and virological breakthrough was similar between patients with or without renal dysfunction. ETV showed high efficacy for all 10 hemodialysis patients without virological breakthrough. Conclusions Entecavir for HBV‐infected patients with severe renal dysfunction, including hemodialysis patients, is highly effective and does not affect renal function.
Background and Aim: Immune checkpoint inhibitors (ICI) have revolutionized anti-malignancy therapy and thus have been increasingly used. Although ICI may cause immune-related adverse events (irAE) in various organs, including the liver, the prevalence and predictive factors of irAE have not been clarified. Methods: In this retrospective study, consecutive patients who had malignancies and were treated with ICI without other chemotherapeutic agents at Hokkaido University Hospital between 2014 and 2019 were screened. Patients were excluded if they were < 20 years old and had insufficient clinical data. Results: Of the 233 patients screened, 202 patients met the inclusion criteria and were included in the analysis. The patients were aged 25-92 years, and 60.9% were male. The patients received nivolumab (n = 137), pembrolizumab (n = 45), ipilimumab (n = 17), atezolizumab (n = 2), and avelumab (n = 1). The prevalence of any grade and grade ≥ 3 irAE hepatitis was 8.4% (17/202) and 4.0% (8/202), respectively. irAE hepatitis occurred at a median duration of 42 days in any grade and 36 days in grade ≥ 3 after ICI initiation. The clinical course of grade ≥ 3 irAE hepatitis was generally favorable; however, 50% required corticosteroid treatment and two patients required additional mycophenolate mofetil. Female sex and history of ICI treatment were significantly associated with the incidence of grade ≥ 3 irAE hepatitis. Conclusions: Grade ≥ 3 irAE hepatitis was observed in 4.0% of the patients who were treated with ICI. Female sex and history of ICI treatment were significantly associated with Squibb, MSD K. K, and Gilead Sciences. Professor Akihiro Homma received lecture fees from Ono Pharmacentical Co., Ltd. Professor the incidence of grade ≥ 3 irAE hepatitis.
