Gastric Pathology and Cancer Risk Assessment

Gastric cancer remains a major global health burden, ranking among the leading causes of cancer-related mortality. Its development is typically understood through a multistep progression, beginning with chronic gastritis and advancing via atrophy, intestinal metaplasia and dysplasia to invasive adenocarcinoma. Epidemiological drivers include Helicobacter pylori infection, dietary factors, genetic predisposition and environmental exposures. Accurate risk assessment relies on integration of histopathology, endoscopic imaging, serological biomarkers and patient demographics to stratify individuals for surveillance or intervention. Endoscopic evaluation has evolved from white-light inspection and biopsy sampling to high-resolution imaging modalities that enable targeted intervention at early stages. Complementary approaches—such as molecular profiling and computational risk modelling—are enhancing predictive precision. Together, these advances promise to shift the clinical paradigm from late-stage treatment toward prevention, early detection and personalised management of premalignant gastric lesions.

Research from Nature Portfolio

A preclinical investigation has demonstrated that endoscopic submucosal injection of umbilical cord-derived mesenchymal stem cells can reverse features of chronic atrophic gastritis in animal models. Treated subjects exhibited restoration of gastric glandular structure, normalisation of serum pepsinogen indices and reduced epithelial apoptosis. In vitro co-culture studies confirmed that these cells enhance gastric epithelial viability, proliferation and migration while down-regulating pro-apoptotic proteins. These findings identify a novel reparative strategy targeting early mucosal injury and suggest potential for regenerative therapies to mitigate progression along the precancerous cascade.

The graph below shows the total number of articles in gastric pathology and cancer risk assessment across all publications each year (not limited to Nature Index journals).

Technical terms

Correa’s cascade: A sequential model describing the progression from chronic gastritis through atrophy, intestinal metaplasia and dysplasia to gastric adenocarcinoma.

Chronic atrophic gastritis: A condition characterised by long-standing inflammation of the stomach lining leading to loss of glandular cells and mucosal thinning.

Intestinal metaplasia: A reversible process in which gastric epithelium is replaced by intestinal-type cells, representing a premalignant change.

Dysplasia: Histological alteration of epithelial cells showing atypia and architectural disarray, regarded as a high-risk precancerous lesion.

Mesenchymal stem cells: Multipotent stromal cells capable of differentiating into diverse cell types and modulating tissue repair mechanisms.

Narrow band imaging: An endoscopic technique that uses specific light wavelengths to enhance visualisation of mucosal and vascular patterns.

Deep neural network: A multilayered computational model designed to recognise complex patterns in large datasets, often used in image analysis.
