The dataset has been developed for the pathology reporting of endoscopic resection (ER) specimens of the stomach. Surgically resected specimens are covered in a separate dataset.

Carcinomas involving the oesophagogastric junction (OGJ) with their epicentre >20 mm into the proximal stomach and cardia cancers that do not involve the OGJ are included. These criteria are set by the World Health Organization and define the diagnosis ‘gastric cancer’. A dataset for oesophageal carcinomas is available for tumours not meeting these criteria.

Neuroendocrine carcinomas (NECs) and mixed neuroendocrine-non-neuroendocrine neoplasms (MiNENs) (with the exception of mixed adenoma and well differentiated neuroendocrine tumours (NETs)) are included in this dataset.

Well differentiated NETs, non-epithelial malignancies, and secondary tumours are excluded from this dataset.
