FUSE Outperforms Forward-viewing Colonoscopy in Detecting Dysplasia in Patients With IBD

The panoramic views obtained with full-spectrum endoscopy (FUSE) increase the number of dysplastic lesions detected in the colon, compared with conventional forward-viewing colonoscopy, researchers report in the May issue of Gastroenterology. Inflammatory bowel diseases (IBDs) increase the risk of colorectal cancer. Surveillance colonoscopy with chromoendoscopy is recommended, but conventional forward-viewing colonoscopy

DDW 2016: Stem Cells Help Heal Perianal Fistulas, Increasing Rates of Colorectal Cancer in Younger Individuals, and Agents Effective Against HCV Genotypes 1–6

Researchers reported important findings on a variety of gastrointestinal and hepatic disorders at Digestive Disease Week in San Diego. – A small, phase 1 study reported that a bioprosthesis plug soaked in autologous mesenchymal stem cells helped heal refractory perianal fistulas that commonly occur in patients with Crohn’s disease.

As Incidence and Deaths from Other Cancers Decrease, Liver Cancer Increases in US

Deaths from almost all cancers in the United States decreased from 1975 to 2012—except for liver cancer. In the Annual Report to the Nation on the Status of Cancer, 1975–2012, published online by the National Cancer Institute, A. Blythe Ryerson et al report that the overall cancer death rates for

Biomarker of Early-stage Aggressive Colon Cancer

Lack of the biomarker CDX2 identifies a subgroup of patients with high-risk stage II colon cancer who appeared to benefit from adjuvant chemotherapy. These patients are usually treated with surgery alone. The findings come from a study published online January 21 in the New England Journal of Medicine. Piero Dalerba

  • Can a Cocktail Prevent Colorectal Adenoma Recurrence?

Can a Cocktail Prevent Colorectal Adenoma Recurrence?

The combination of calcitriol, aspirin, and calcium carbonate did not prevent recurrence of colorectal adenomas over a 3-year period, found a prospective study published in the January issue of Gastroenterology. This negative result might have been affected by the numbers of smokers included in the study or low doses of

Do Patients Really Prefer Colon Capsule Endoscopy Over Colonoscopy?

Slightly more than 50% of people with an inherited risk for colorectal cancer (CRC) agree to undergo screening for this cancer, and most prefer colonoscopy to colon capsule endoscopy—even though these are equally effective screening tools—researchers report in the December issue of Clinical Gastroenterology and Hepatology. Colonoscopy should therefore remain

Special Issue: Genetics, Genetic Testing, and Biomarkers of Digestive Diseases

A special issue of Gastroenterology features 14 articles discussing the genetic factors that contribute to a range of gastrointestinal (GI),  hepatobiliary, and pancreatic diseases, and how this information can be used in diagnosis and treatment of patients. An introduction to the special issue explains the value of associating diseases with specific genetic variants, which can help

Expert Panel Recommends Aspirin Therapy for Prevention of Colorectal Cancer

For the first time, an expert panel has recommended aspirin therapy to prevent not only heart attacks but also colorectal cancer. The guideline for those at high risk of heart disease, published September 14 in a draft report from the US Preventive Services Task Force is the first time a major

How do Differentiated Tumor Cells Support Cancer Stem Cells?

Differentiated colorectal cells produce stem cell factor (SCF) to activate KIT signaling in tumor-initiating cells, researchers report in the September issue of Gastroenterology. This pathway maintains the stem-like features of these tumor cells, predominantly under conditions of hypoxia. Colorectal tumors are organized hierarchically and their growth is mediated by an

VEGF Signaling Prevents Senescence in Colorectal Tumors

Vascular endothelial growth factor receptor-2 (VEGFR2) signaling prevents senescence of colorectal cancer cells by inactivating p21, researchers report in the July issue of Gastroenterology. Inactivation of this pathway correlates with survival of patients treated with anti-VEGF cancer drug bevacizumab. VEGF, a growth factor that has been well studied for its
