Endoscopic Resection of the Stomach


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 ICCR 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 Union for International Cancer Control/American Joint Committee on Cancer 8th edition TNM classifications and have been adopted by the World Health Organization and define the diagnosis ‘gastric cancer’. An ICCR dataset for carcinoma of the oesophagus 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 neuroendocrine tumours (NETs)) are included in this dataset.

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