The dataset has been developed for the pathology reporting of gastrectomy for gastric carcinomas. A separate dataset is available for endoscopic resections of the stomach.

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’. For all other tumours involving the OGJ, please refer to the dataset for oesophageal cancers. 

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.
