How Do Diet and Antibiotic Use Affect Risk of Colorectal Tumor Recurrence?

Researchers have identified mechanisms by which diet and antibiotic use together promote tumorigenesis by colon cancer cells at the anastomosis after colorectal surgery, reported in the March issue of Gastroenterology. Strategies to prevent emergence of these microbe communities or their enzymatic activities might be used to reduce the risk of

REVIEW: All About Gastric (Stomach) Cancer

Despite the worldwide decrease in gastric cancer incidence and mortality over the past 5 decades, it is still the third-leading cause of cancer-related death. Understanding the epidemiology and risk factors for gastric cancer can aide in determination of risk, screening, and prevention. In the March issue of Clinical Gastroenterology and

  • What are the Risk Factors for Nonalcoholic Fatty Liver Disease in Patients With Type 2 Diabetes?

What are the Risk Factors for Nonalcoholic Fatty Liver Disease in Patients With Type 2 Diabetes?

Persons with type 2 diabetes have a more than 2-fold increase in risk for severe liver disease, researchers report in the December issue of Clinical Gastroenterology and Hepatology. The authors found risk factors that might be used to identify persons with type 2 diabetes who should be screened for liver disease.

  • Does DAA Therapy for HCV Infection Increase Survival in Patients Who Have Responded to Treatment for Hepatocellular Carcinoma?

Does DAA Therapy for HCV Infection Increase Survival in Patients Who Have Responded to Treatment for Hepatocellular Carcinoma?

In patients who have received successful treatment for HCV-related hepatocellular carcinoma (HCC), eradication of the HCV infection with direct-acting antiviral (DAA) significantly reduces risk of death, researchers report in the November issue of Gastroenterology. Chronic hepatitis C virus (HCV) infection is the most common cause of HCC in North America and Europe. DAA

  • Review Article: What are Serrated Colorectal Polyps?

Review Article: What are Serrated Colorectal Polyps?

Serrated polyps comprise hyperplastic polyps, sessile serrated lesions (SSLs), and traditional serrated adenomas (TSAs). Approximately 25% of sporadic colorectal cancers (CRCs) arise from serrated precursor lesions, but there is confusion regarding their terminology, classification, and risk. A review article by Seth D. Crockett and Iris D. Nagtegaal in the October issue of Gastroenterology clarifies

  • What Drugs Can Reduce Risk of Colorectal Cancer?

What Drugs Can Reduce Risk of Colorectal Cancer?

Use of phosphodiesterase 5 (PDE5) inhibitors (commonly used to treat erectile dysfunction) is associated with a 35% reduction in risk of colorectal cancer (CRC) among male patients with benign colorectal neoplasms, researchers report in the September issue of Gastroenterology. The decreased risk of CRC was associated with an increased cumulative dose

  • REVIEW: How Does Barrett’s Esophagus Develop?

REVIEW: How Does Barrett’s Esophagus Develop?

Mechanisms of Barrett’s esophagus (BE) pathogenesis are discussed in a review article by Jianwen Que et al in the August issue of Gastroenterology, including cell transdifferentiation and transcommitment. The authors discuss potential cells of origin for Barrett’s metaplasia, and the possibility that there could be more than 1 type of BE

  • How Does Gastric Adenocarcinoma Develop?

How Does Gastric Adenocarcinoma Develop?

Overexpression of the peroxisome proliferator-activated receptor delta (PPARD) in gastric progenitor cells results in inflammation, dysplasia, and tumor formation in mice, researchers report in the July issue of Gastroenterology. Strategies to reduce PPARD in gastric progenitor cells might lead to treatments for stomach cancer. Gastric carcinogenesis is associated with chronic inflammation. The

  • Why Are Patients Cured of HCV Infection Still at Risk for Liver Cancer?

Why Are Patients Cured of HCV Infection Still at Risk for Liver Cancer?

Chronic infection with the hepatitis C virus (HCV) causes epigenetic changes in liver cells that alter gene expression patterns and continue to affect risk for hepatocellular carcinoma (HCC), regardless of patients’ response to direct-activating antiviral (DAA) agents, researchers report in the June issue of Gastroenterology. These alterations might be targeted

  • Are There Early Signs of Pancreatic Cancer?

Are There Early Signs of Pancreatic Cancer?

Changes in blood glucose and lipid levels occur up to 18 months before a diagnosis of pancreatic cancer, researchers report in the May issue of Gastroenterology. These changes might be used in combination with other risk factors to detect pancreatic cancer at earlier stages. One reason for the high mortality
