Ramucirumab in patients with previously treated advanced hepatocellular carcinoma: Impact of liver disease aetiology.
2021
BACKGROUND & AIMS Hepatocellular carcinoma (HCC) is a common complication of chronic liver disease with diverse underlying aetiologies. REACH/REACH-2 were global phase III studies investigating ramucirumab in advanced HCC (aHCC) following sorafenib treatment. We performed an exploratory analysis of outcomes by liver disease aetiology and baseline serum viral load. METHODS Meta-analysis was conducted in patients with aHCC and alpha-fetoprotein (AFP) ≥400 ng/mL (N = 542) from REACH/REACH-2 trials. Individual patient-level data were pooled with results reported by aetiology subgroup (hepatitis B [HBV] or C [HCV] and Other). Pre-treatment serum HBV DNA and HCV RNA were quantified using Roche CO…
Drug Treatment for Chronic Hepatitis C Infection and Cancer Risk
2017
BACKGROUND In patients with chronic hepatitis C infection, a sustained virologic response (SVR) to interferon-based therapy markedly decreases the incidence of hepatocellular carcinoma (HCC) over the long term. This is also true for patients who have hepatic cirrhosis, as well as for those with HCC-with or without cirrhosis-who have undergone resection or ablation with curative intent. Recent publications, however, have reported a higher incidence of HCC among patients in both of these subgroups who were treated with direct antiviral agents (DAA) rather than interferon-based therapy. METHODS A selective search for pertinent literature was carried out in the PubMed database with the search t…
Interreader Reliability of LI-RADS Version 2014 Algorithm and Imaging Features for Diagnosis of Hepatocellular Carcinoma: A Large International Multi…
2017
Purpose To determine in a large multicenter multireader setting the interreader reliability of Liver Imaging Reporting and Data System (LI-RADS) version 2014 categories, the major imaging features seen with computed tomography (CT) and magnetic resonance (MR) imaging, and the potential effect of reader demographics on agreement with a preselected nonconsecutive image set. Materials and Methods Institutional review board approval was obtained, and patient consent was waived for this retrospective study. Ten image sets, comprising 38-40 unique studies (equal number of CT and MR imaging studies, uniformly distributed LI-RADS categories), were randomly allocated to readers. Images were acquired…
Screening and surveillance for hepatocellular carcinoma: perspective of a new era?
2016
Hepatocellular carcinoma (HCC) is the fifth most common cancer and the third most common cause of cancer-related death with an increasing prevalence worldwide. Early diagnosis of HCC is important since observational studies have reported that, in patients undergoing surveillance, cancer is diagnosed at an earlier stage with increased chances of curative therapies. Anyway, despite the extensive use of screening for HCC, its effectiveness is still a controversial topic since supporting evidence is not unequivocal and some issues need to be explored. Areas covered: The aim of this paper is to review main literature data supporting performance and effectiveness of screening for early detection …
Management of hepatitis C virus genotype 4: recommendations of an international expert panel.
2011
HCV has been classified into no fewer than six major genotypes and a series of subtypes. Each HCV genotype is unique with respect to its nucleotide sequence, geographic distribution, and response to therapy. Genotypes 1, 2, and 3 are common throughout North America and Europe. HCV genotype 4 (HCV-4) is common in the Middle East and in Africa, where it is responsible for more than 80% of HCV infections. It has recently spread to several European countries. HCV-4 is considered a major cause of chronic hepatitis, cirrhosis, hepatocellular carcinoma, and liver transplantation in these regions. Although HCV-4 is the cause of approximately 20% of the 170 million cases of chronic hepatitis C in th…
Targetoid appearance on T2-weighted imaging and signs of tumor vascular involvement: diagnostic value for differentiating HCC from other primary live…
2021
To evaluate targetoid appearance on T2-weighted imaging and signs of tumor vascular involvement as potential new LI-RADS features for differentiating hepatocellular carcinoma (HCC) from other non-HCC primary liver carcinomas (PLCs). This IRB-approved, retrospective study was performed at two liver transplant centers. The final population included 375 patients with pathologically proven lesions imaged between 2007 and 2017 with contrast-enhanced CT or MRI. The cohort consisted of 165 intrahepatic cholangiocarcinomas and 74 combined hepatocellular-cholangiocarcinomas, with the addition of 136 HCCs for control. Two abdominal radiologists (R1; R2) independently reviewed the imaging studies (112…
Long-term observation of hepatocellular carcinoma recurrence after liver transplantation at a European transplantation centre
2019
BACKGROUND: The recurrence of hepatocellular carcinoma (HCC) is the strongest survival-limiting factor after liver transplantation (LT) in patients with HCC. In the face of donor organ shortage, it is necessary to identify factors associated with HCC recurrence in order to maximize the utility of the available grafts. OBJECTIVE: To study the phenomenon of HCC recurrence after LT at a European transplantation centre over the past 20 years. METHODS: Data from 304 HCC patients who underwent LT were prospectively recorded. Clinical and pathological factors were assessed for their association with recurrence. RESULTS: Fifty-one patients (16.8%) had HCC recurrence after LT. Patients exceeding the…
A Review of the Cardiovascular and Anti-Atherogenic Effects of Ghrelin
2013
Ghrelin is a peptide hormone produced mainly in the stomach that has widespread tissue distribution and diverse hormonal, metabolic and cardiovascular activities. The circulating ghrelin concentration increases during fasting and decreases after food intake. Ghrelin secretion may thus be initiated by food intake and is possibly controlled by nutritional factors. Lean subjects have increased levels of circulating ghrelin compared with obese subjects. Recent reports show that low plasma ghrelin is associated with elevated fasting insulin levels, insulin resistance and type 2 diabetes mellitus. Factors involved in the regulation of ghrelin secretion have not yet been defined; however, it is as…

Autoimmune hepatitis and overlap syndromes
2002
Autoimmune hepatitis (AIH) is an immune-mediated, autodestructive liver disease with hepatocytes as target cells, mostly affecting young women. Primary biliary cirrhosis (PBC) is also regarded as an autoimmune liver disease with bile duct epithelia as the target cells, resulting in a continuous loss of bile ducts. Both diseases may occur simultaneously in their full manifestations in about 10% to 20% of cases, thus constituting an overlap syndrome with PBC directing the course of the disease. AIH may also occur simultaneously with primary sclerosing cholangitis (PSC), with a frequency of between 2% and 8% of patients with PSC. In most cases, AIH precedes manifestation of PSC. In children, t…
