The Wisteria floribunda agglutinin-positive human Mac-2-binding protein (WFA+-M2BP) was recently shown to be a liver fibrosis glycobiomarker with unique fibrosis-related glycoalteration. We evaluated the ability of WFA+-M2BP predict development hepatocellular carcinoma (HCC) in patients who were infected hepatitis C virus (HCV). A total 707 had been admitted our hospital chronic HCV infection without other potential risk factors determine HCC; included age, sex, viral load, genotypes, stage,...

Abstract Although the use of immune checkpoint inhibitors (ICIs)-targeted agents for unresectable hepatocellular carcinoma (HCC) is promising, individual response variability exists. Therefore, we developed an artificial intelligence (AI)-based model to predict treatment efficacy using pre-ICIs contrast-enhanced computed tomography (CT) imaging characteristics. We evaluated atezolizumab and bevacizumab in 43 patients at Nagasaki University Hospital from 2020 2022 modified Response Evaluation...

Background: Lenvatinib is currently available as the first-line treatment for advanced unresectable hepatocellular carcinoma. We evaluated relationship between its relative dose intensity (RDI) and response in clinical settings. Methods: From March 2018 to May 2019, 93 patients were administered lenvatinib at Nagasaki University Hospital related facilities. Among these, 81 (66 men, 15 women, median age 72.0) who received analyzed retrospectively. Results: Fourteen Child–Pugh grade B, had...

Atezolizumab plus bevacizumab therapy has high response rates in patients with unresectable hepatocellular carcinoma (HCC). The hepatobiliary phase of gadoxetic acid-enhanced magnetic resonance imaging (EOB-MRI) been reported to be useful as an biomarker for detecting β-catenin mutations. We evaluated whether the pretreatment EOB-MRI could predict therapeutic effect lenvatinib and atezolizumab bevacizumab.This study included 68 (lenvatinib group (n = 33) 35)). visual assessment relative...

We investigated kinetics serum HBsAg before in patients with B.We retrospectively analyzed 392 Japanese who had been followed for 5 years or more between 1980 and 2000. levels were measured annually using chemiluminescent enzyme immunoassay.During a median follow up 14 years, 50 demonstrated (annual incidence rate, 0.91%). Multivariate analysis baseline characteristics revealed that...

Immune checkpoint inhibitors (ICIs) have proven to be effective treatments for various cancers, but can also elicit immune-related adverse events (irAEs). Given that severe irAEs life-threatening, biomarkers predict the occurrence of are paramount importance. ICIs affect dynamics lymphocytes, and alterations in these may play a role development severity irAEs. The aim this study was investigate correlation between changes lymphocyte counts.Information on collected from 226 ICI cases 2014...

Posttransplant liver steatosis occurs frequently and can affect patient outcome. Our aim was to clarify the risk factors for or steatohepatitis after living donor transplantation (LT) through a retrospective examination of recent 100 LT recipients their donors.Liver biopsy performed at 1 year each year, thereafter, as needed due abnormal enzyme levels, with median follow-up 4 years (2-10 years).Liver (≥5%) identified in 33 cases, 9 patients steatosis.
