Background and Rationale: Immune checkpoint inhibitor (ICI) therapy is an expanding therapeutic option for hepatocellular carcinoma (HCC). Antibiotics (ATB) taken prior to or early during ICI therapy can impact immunotherapy efficacy across indications; however, the effect of ATB is undefined in HCC. Methods: In a large international cohort of 450 ICI recipients from Europe, North America, and Asia

Introduction: Serum α-fetoprotein (AFP), Lens culinaris agglutinin-reactive AFP (AFP-L3), and des-γ-carboxy­pro­thrombin (DCP) are useful biomarkers of hepatocellular carcinoma (HCC). However, associations among molecular characteristics and serum biomarkers are unclear. We analyzed RNA expression and DNA variant data from The Cancer Genome Atlas Liver Hepatocellular Carcinoma (TCGA-LIHC) to examine

Background: Cholangiocarcinoma (CCA) encompasses a heterogeneous group of malignant tumors with dismal prognosis and increasing incidence worldwide. Both late diagnosis due to the lack of early symptoms and the refractory nature of these tumors seriously compromise patients’ welfare and outcomes.

Background: It is unclear whether entecavir (ETV) and tenofovir disoproxil fumarate (TDF) have different effects on hepatocellular carcinoma (HCC) recurrence and death in patients receiving curative hepatectomy for hepatitis B virus (HBV)-related HCC. Aims: The aim of this study was to compare the long-term efficacy of ETV and TDF in HCC recurrence and overall survival (OS) of patients after curative

Background and Aims: Current prediction models for early recurrence of hepatocellular carcinoma (HCC) after surgical resection remain unsatisfactory. The aim of this study was to develop evolutionary learning-derived prediction models with interpretability using both clinical and radiomic features to predict early recurrence of HCC after surgical resection. Methods: Consecutive 517 HCC patients receiving

Introduction: In spite of the high frequency of recurrence of hepatocellular carcinoma (HCC) after resection, little evidence exists to directly help to plan a reasonable schedule for the frequency and intensity of postoperative surveillance for recurrence. Methods: 1,918 consecutive patients with Child-Turcott-Pugh class A who had T1- or T2-staged HCCs detected by active surveillance and underwent

Background: The mammalian target of rapamycin (mTOR) pathway is upregulated in nearly half of hepatocellular carcinoma (HCC) tumors and is associated with poor prognosis. In preclinical models of HCC, the combination of mTOR pathway inhibition with the multikinase inhibitor sorafenib improves treatment efficacy. A prior phase I study of the allosteric mTOR inhibitor temsirolimus combined with sorafenib
