Background: Management of single small hepatocellular carcinoma (HCC) is straightforward with curative outcomes achieved by locoregional therapy or resection. Liver transplantation is often considered for multiple small or single large HCC. Management of two small HCC whether presenting synchronously or sequentially is less clear.

Objective The aims of this study were to: (1) identify the characteristics of patients with chronic hepatitis B (CHB) who do not attend their hospital liver clinic appointments; and (2) raise awareness among general practitioners (GP) of alternative pathways to care for CHB in order to prevent long-term complications of CHB (liver cancer and cirrhosis). Methods This prospective study was conducted between May 2018 and January 2019 at one site of a tertiary referral hospital in western Melbourne. Patients with minimal liver complications who did not attend their first two initial appointments were included in the study, in addition to referring GPs of new CHB patients to the liver clinic who had minimal liver complications (characterised by minimal fibrosis (<7kPa)) and no liver comorbidities (including cirrhosis and/or hepatocellular carcinoma).

Background And Aim: The prevalence of primary biliary cholangitis (PBC) reported in different countries varies significantly and in some parts of the world appears to be increasing. The aim of this study was to determine the 2013 prevalence of PBC in Victoria, Australia, and to determine the time trend by comparing it with previous studies undertaken in 1991 and 2002.

Methods: Four case-finding methods were used to identify cases of PBC in Victoria: (1) physicians' survey; (2) tertiary hospital search; (3) liver transplant database search; and (4) private pathology antimitochondrial antibody search.

Introduction: Despite highly effective direct-acting antiviral (DAA) therapies for chronic hepatitis C virus (HCV) infection, some patients experience virological relapse. Salvage regimens should include multiple agents to suppress emergence of resistance-associated substitutions (RAS) and minimise treatment failure. The combination of sofosbuvir (SOF) and elbasvir/grazoprevir (ELB/GZR) ±ribavirin (RBV) is an effective retreatment strategy for HCV genotype (GT)1 and 4 infection.

Objectives: To determine the factors associated with survival of patients with hepatocellular carcinoma (HCC) and the effect of HCC surveillance on survival.

Design, Setting And Participants: Prospective population-based cohort study of patients newly diagnosed with HCC in seven tertiary hospitals in Melbourne, 1 July 2012 - 30 June 2013.

Main Outcome Measures: Overall survival (maximum follow-up, 24 months); factors associated with HCC surveillance participation and survival.

Objective: Sorafenib is an oral multikinase inhibitor that improves survival in advanced hepatocellular carcinoma (HCC). In the absence of alternative therapies, sorafenib is often continued despite advancing liver disease or tumour progression. Real world studies are important to better characterise outcomes in these populations.

Background: Tumor associated macrophages are present in hepatocellular carcinoma (HCC) and associated with a poor prognosis. The aim of the present study was to investigate the levels and dynamics of soluble (s)CD163, a specific macrophage activation marker, in patients with HCC.

Methods: In a cohort from Australia, we studied 109 HCC patients, 116 patients with chronic liver disease (CLD), and 52 healthy controls.

Unlabelled: Hepatocellular carcinoma (HCC) incidence is rising rapidly in many developed countries. Primary epidemiological data have invariably been derived from cancer registries that are heterogeneous in data quality and registration methodology; many registries have not adopted current clinical diagnostic criteria for HCC and still rely on histology for classification. We performed the first population-based study in Australia using current diagnostic criteria, hypothesizing that HCC incidence may be higher than reported.

Background And Aim: The glycoprotein CD147 has a role in tumor progression, is readily detectable in the circulation, and is abundantly expressed in hepatocellular carcinoma (HCC). Advanced HCC patients are a heterogeneous group with some individuals having dismal survival. The aim of this study was to examine circulating soluble CD147 levels as a prognostic marker in HCC patients.

Background: The vitamin B12 (B12)-binding protein haptocorrin (HC) has proven to be a potentially useful biomarker in patients with fibrolamellar hepatocellular carcinoma (HCC). Little is known concerning the level of HC and other B12-related proteins in patients with HCC as compared to patients with other chronic liver diseases (CLDs) and healthy controls. We hypothesized that HC could be a biomarker of HCC.
