Abstract
Recently, Gut published a review of guidelines for the management of gastric intestinal metaplasia (GIM) with the goal of promoting harmonisation of the guidelines regarding indications for endoscopic screening for gastric cancer and GIM detection/staging, metrics for high-quality endoscopy and non-endoscopic interventions for gastric cancer prevention in patients with GIM.1 GIM is not a disease per se but rather is a reparative response to gastric mucosal injury that may be present, at least temporarily, as part of healing such as of an ulcer.2 Clinically, widespread GIM is best considered a manifestation of healing of another disease, typically Helicobacter pylori infection or autoimmune gastritis. When present in autoimmune gastritis, GIM has no malignant potential and is potentially completely reversible.3 In contrast, when associated with chronic H. pylori infection, GIM is typically permanent and, at most, minimally reversible.4 The underlying H. pylori -induced inflammation is carcinogenic. H. pylori -related GIM is a manifestation of the duration, extent and severity of an H. pylori infection which, in turn, is related to the risk of gastric cancer. Because GIM is easily recognised and reflects the extent and severity of the infection, it is a valuable surrogate for the risk of developing gastric cancer. This has given GIM a role in the determination of an individual’s cancer risk. However, because GIM is neither a disease nor a cause of cancer, eradication of gastric cancer should focus on the eradication of the cause, that is, H. pylori infections. The population …
期刊介绍:
Gut is a renowned international journal specializing in gastroenterology and hepatology, known for its high-quality clinical research covering the alimentary tract, liver, biliary tree, and pancreas. It offers authoritative and current coverage across all aspects of gastroenterology and hepatology, featuring articles on emerging disease mechanisms and innovative diagnostic and therapeutic approaches authored by leading experts.
As the flagship journal of BMJ's gastroenterology portfolio, Gut is accompanied by two companion journals: Frontline Gastroenterology, focusing on education and practice-oriented papers, and BMJ Open Gastroenterology for open access original research.
