Can Exposure to Aflatoxin Cause Gallbladder Cancer?

Exposure to aflatoxin increases risk of gallbladder cancer, researchers report in the September issue of Gastroenterology. Ingestion of aflatoxin, produced by a fungi that grows on corn and peanuts, could account for the high incidence of gallbladder cancers in some regions of China and Chile. Gallbladder cancer, the most common biliary tract cancer, has

Bioinformatic Search Identifies Tapeworm Drug for Treatment of Hepatocellular Carcinoma

In a bioinformatic search for agents that alter the hepatocellular carcinoma (HCC)-specific gene expression pattern, researchers identified the anthelmintic drug niclosamide as a potential anti-tumor agent, described in the June issue of Gastroenterology. Niclosamide and its ethanolamine salt (NEN), with greater bioavailability, slowed growth of genetically induced liver tumors and

  • What are the Different Types of Liver Cancer, and How do They Develop?

What are the Different Types of Liver Cancer, and How do They Develop?

A review article in the March issue of Gastroenterology discusses different hypotheses about the cells responsible for liver tumorigenesis. The article also reviews the different classes of liver tumors, based on the molecular features, and how these affect patient prognosis. Daniela Sia et al describe the distinct molecular and clinical features of hepatocellular

  • How Can We Study Genetic Heterogeneity Within Hepatocellular Carcinomas?

How Can We Study Genetic Heterogeneity Within Hepatocellular Carcinomas?

Researchers have developed a patient-derived cell line-based model to study how intratumor heterogeneity affects sensitivity of hepatocellular carcinoma (HCC) to different therapeutic agents, reported in the January issue of Gastroenterology. HCCs have a large amount of genetic heterogeneity within each tumor, making them difficult to treat. Multiple regions of tumors

  • A Forward Genetic Screen Identifies Suppressors of Hepatocellular Carcinogenesis

A Forward Genetic Screen Identifies Suppressors of Hepatocellular Carcinogenesis

Using 2 powerful high-throughput in vivo screening tools, researchers identified and validated 27 genes as suppressors of hepatocellular carcinoma (HCC), reported in the August issue of Gastroenterology. Their findings support the role of Ras signaling in development of HCC and provide new therapeutic targets. Sorafenib is the only treatment for patients

  • A Nanoparticle-based Approach to Selectively Target Hepatocellular Carcinomas

A Nanoparticle-based Approach to Selectively Target Hepatocellular Carcinomas

Researchers have created nanoparticles that selectively kill hepatoma cells and reduce growth of liver tumors in rats, they report in the February issue of Gastroenterology. They show that the particles induce tumor-specific necrosis by selectively disrupting redox balance within cancer cells. Dietary intake of the natural omega-3 fatty acid docosahexaenoic

Special Issue: Managing Patients With Liver Disease

A special issue of Clinical Gastroenterology and Hepatology is dedicated to the clinical management of hepatic disorders, including nonalcoholic fatty liver disease (NAFLD), viral hepatitis, autoimmune hepatitis, and primary sclerosing cholangitis (PSC). The issue comprises 14 review articles that aim to present clinicians with evidence-based guidance and expert opinions on management of patients with liver

What is This Liver Tumor?

Researchers describe a rare liver tumor of vascular origin in the May issue of Clinical Gastroenterology and Hepatology. Laisa Socorro Briongos-Figuero and Tomás Zamora-Martínez describe the case of a 59-year-old man with chronic pancreatitis who was was admitted to the hospital with vomiting and jaundice, without fever or diarrhea. He had a previous history of

What is Intrahepatic Cholangiocarcinoma?

Researchers have found that intrahepatic cholangiocarcinomas (ICCs) are really 2 different groups of tumors, based on molecular and genetic analyses, reported in the April issue of Gastroenterology. These findings identify class-specific mechanisms of oncogenesis that could lead to new treatment approaches for this common liver cancer. Cholangiocarcinoma is the second most

Differences in HCV Infection, and Effects of Treatment, Among Countries

Hepatitis C virus (HCV) infections have developed and spread at different rates in different countries, affecting outcomes of therapy, according to the October issue of Gastroenterology. Specific details of each population must therefore be considered in designing prevention and treatment programs. Although there are many treatment options for HCV infection,
