Duodenal NET (dNET) - Ronny Allan - Living with Neuroendocrine Cancer

Tag: Duodenal NET (dNET)

NETs located in the duodenum are increasingly detected in early, easily treatable stages. Smaller tumours are mostly non-functional (hormone inactive) and usually do not cause any discomfort. Duodenal NETs are often found incidentally during a gastroscopy that is being carried out for other reasons. If duodenal NETs present with a hormonal hypersecretion syndrome (Zollinger-Ellison or carcinoid syndrome), the situation can be different with many presenting at more advanced stages. It is estimated that around a quarter of all NETs of the small intestine arise from the duodenum.

European Neuroendocrine Tumor Society (ENETS) 2023 guidance paper for Duodenal neuroendocrine tumours (NETs) G1–G3

Latest ENETS Guidelines

The ENETS 2023 guideline for dNETs are combined with the guidelines for Gastric NET (gNET) due to their close relationship in anatomical terms. But there are functional linkages to the pancreas, therefore also links to that as above. The duodenum is technically part of the small intestine, and you can find that in most anatomy-based descriptions. One of the research references I used was titled “Somewhere between the pancreas and the small intestine” and in the case of Duodenal NENs (dNENs), I can understand why they adopted that unconventional anatomy description. I suspect they contextually meant that they are not like either of these organs, but they share some similarities. This seems at odds with the ENETs decision to link guidelines for stomach and duodenal in one. They are not…

Summary - June was a relatively quiet month on my website RonnyAllan.NET - mainly due to me being on holiday for much of it! However, a respectable 18,000 blog views are not to be sniffed at!

A spotlight on duodenal Neuroendocrine Neoplasms (dNENs)

A spotlight on NENs - Types

What are Duodenal Neuroendocrine Neoplasms (dNEN)? The duodenum is technically part of the small intestine, and you can find that in most anatomy-based descriptions. One of the research references I used was titled "Somewhere between the pancreas and the small intestine" and in the case of Duodenal NENs (dNENs), I can understand why they adopted that unconventional anatomy description. I suspect they contextually meant that they are not like either of these organs, but they share some similarities. They are not normally treated like small intestine NETs (SI NETs) or pancreatic NETs (pNETs) but they share some relationships, particularly with the latter. They are also closely aligned to the stomach (Gastric NENs) in terms of symptoms and syndromes that they sometimes present. Although they are a type of NEN (i.e. dNENs),…
