The dataset has been developed for the pathology reporting of gastrectomy for gastric carcinomas. A separate ICCR 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 Union for International Cancer Control/American Joint Committee on Cancer 8th edition Classifications and have been adopted by the World Health Organization to define the diagnosis ‘gastric cancer’. For all other tumours involving the OGJ, refer to the ICCR dataset for carcinomas of the oesophagus.
Neuroendocrine carcinomas (NECs) and mixed neuroendocrine-non-neuroendocrine neoplasms (MiNENs) (with the exception of mixed adenoma and neuroendocrine tumours (NETs)) are included in this dataset.
NETs, non-epithelial malignancies and secondary tumours are excluded from this dataset.
