Can GastroPanel be used as a triage tool to select patients with advanced atrophic gastritis for gastroscopy? A prospective clinical validation study.

Objective: Gastric adenocarcinoma (GAC) is the 17th most common cancer in the UK with a 5-year survival rate of 22%. GastroPanel (Biohit Oyj; Helsinki, Finland) is an ELISA kit that measures pepsinogen I (PGI); pepsinogen II (PGII); gastrin-17 (G-17); and Helicobacter pylori IgG antibodies (Hp IgG). PGI and the PGI/PGII ratio correlate inversely with the severity of chronic atrophic gastritis (AG).

Update from 2010 (standard operating procedure): protocol for the 2024 British Society of Gastroenterology Guidelines on colorectal surveillance in inflammatory bowel disease.

Introduction: The evolving landscape of inflammatory bowel disease (IBD) necessitates refining colonoscopic surveillance guidelines. This study outlines methodology adopted by the British Society of Gastroenterology (BSG) Guideline Development Group (GDG) for updating IBD colorectal surveillance guidelines.

Methods And Analysis: The 'Grading of Recommendations, Assessment, Development and Evaluation' (GRADE) approach, as outlined in the GRADE handbook, was employed.

Goblet cell differentiation subgroups in colorectal cancer.

The poor prognosis of relatively undifferentiated cancers has long been recognized, suggesting that selection against differentiation and in favor of uncontrolled growth is one of the most powerful drivers of cancer progression. Goblet cells provide the mucous surface of the gut, and when present in colorectal cancers (CRC), the cancers are called mucinous. We have used the presence of MUC2, the main mucous product of goblet cells, and an associated gene product, TFF3, to classify a large panel of nearly 80 CRC-derived cell lines into five categories based on their levels of MUC2 and TFF3 expression.
