The current WHO rulebook for cancers of the gut, which among other changes renamed goblet cell carcinoid as goblet cell adenocarcinoma, adopted the LAMN terminology for appendiceal tumours and re-graded neuroendocrine neoplasms.
Overview by the WHO Classification of Tumours Editorial Board of the fifth-edition digestive system volume, summarising changes across oesophagus, stomach, small bowel, appendix, colorectum, liver, biliary tract and pancreas.
For the appendix it adopts low-grade and high-grade appendiceal mucinous neoplasm and reclassifies goblet cell carcinoid as goblet cell adenocarcinoma with a three-tier grade; it also separates neuroendocrine tumours from neuroendocrine carcinomas and introduces molecular subtypes across sites.
The names on an appendix or small bowel pathology report, and hence which OnCo subtype page applies, follow this classification.
