How Does a High-Fat Diet Contribute to Pancreatic Cancer?

A high-fat diet can promote development of pancreatic cancer, but cyclooxygenase-2 (COX2) inhibitors prevent this process, according to a mouse study published in the December issue of Gastroenterology. The mechanisms appear to involve activation of oncogenic KRAS and upregulation of COX2, which promotes pancreatic inflammation. Increased body mass index and

Which Patients With Barrett’s Esophagus Will Develop Esophageal Cancer?

Researchers have found markers to identify patients with Barrett’s esophagus (BE) at greatest risk of developing esophageal adenocarcinoma. These are described in the August issue of Clinical Gastroenterology and Hepatology. In patients with BE, part of the normal stratified squamous epithelium of the lower esophagus is replaced with metaplastic columnar

Are All Patients With IBD at Increased Risk for Colorectal Cancer?

Although inflammatory bowel disease (IBD) increases risk for colorectal cancer (CRC), the risk is only substantial among patients with long-term, extensive colitis. Furthermore, CRC risk is reduced by thiopurine therapy, according to the July issue of Gastroenterology. Laurent Beaugerie et al. collected data from 19,486 patients with IBD (60% with

How Can We Screen for Pancreatic Cancer and its Precursors?

Individuals with invasive pancreatic cancer or high-grade dysplasia can be identified based on a specific DNA mutation in pancreatic juice samples from the duodena, according to the June issue of Clinical Gastroenterology and Hepatology. Tests for mutant TP53 might be developed to improve the diagnosis of and screening for pancreatic cancer and its precursors.

Should Everybody Be Tested for Celiac Disease?

Not only does celiac disease cause abdominal pain, diarrhea, and bloating—untreated disease leads to progressive bone loss and derangements, increasing the risk for early osteoporosis and fractures of the hip and vertebrae. The June issue of Clinical Gastroenterology and Hepatology reports that current screening strategies to identify people with celiac

What are the Risks for Relatives of Patients With Colorectal Cancer?

Close relatives of people with colorectal cancer (CRC) have a significant increase in prevalence of advanced neoplasms and should be screened for cancer, according to the March issue of Gastroenterology. Relatives of patients with CRC have been shown to be at increased risk for colorectal neoplasms, but little is known

Does Depression Increase the Risk for Inflammatory Bowel Disease?

Depression increases the risk for Crohn’s disease in women, according to a study published in the January issue of Clinical Gastroenterology and Hepatology. Psychological factors might therefore contribute to development of this disorder. Anxiety, depression, and other psychological disorders are common in people with Crohn’s disease (CD) and ulcerative colitis

Why Does Colonoscopy Protect Against Left-Sided Cancers?

Polyps with advanced pathology are significantly smaller in the right than left colon, and are therefore more likely to be missed during colonoscopy examinations, according to the December issue of Clinical Gastroenterology and Hepatology. Mortality from colorectal cancer (CRC) is decreasing, in part because colonoscopy screening is increasing, leading to

How Common is Portal Hypertension in Patients With NAFLD?

Patients with nonalcoholic fatty liver disease (NAFLD) are at risk for portal hypertension and esophageal varices, according to the September issue of Clinical Gastroenterology and Hepatology. The study also shows that factors such as advanced liver disease, type 2 diabetes, and obesity can be used to identify patients most likely
