Neuroendocrine Cancer: Glossary of Terms
Welcome to my Neuroendocrine Cancer Glossary of Terms list providing a source of meanings for acronyms and medical terms, all sourced from top Neuroendocrine Cancer and general cancer sites. How to use this database:1. If your term begins with an A, click on A to find all terms beginning with A. Select your terms beginning with A from the filtered list.2. For numerical terms (e.g. 5HIAA etc), please click on the hashtag (#) symbol in the A-to-Z strip.3. The term definition including acronym or abbreviation will be given in full along with any of my published articles containing that term as…
Carcinoid vs Neuroendocrine
OPINION - There's a constant debate regarding the validity of the term 'Carcinoid'. I've posted about this a few times and as far as I know, the debate has been raging for some years. This post was originally generated in April 2015 (and hasn't changed that much!). EDIT MARCH 2024. There is now a consolidated Endocrine/Neuroendoceine Tumour classification system (Blue Book). Still in print but you can see a summary of changes by clicking here. This change should provide some leverage to Neuroendocrine committees particularly about what things should be called. EDIT MARCH 2022. The latest classification system for Lung…
Neuroendocrine Cancer – Horrible Hormones
Updated and reviewed 20th March 2024 Hormonal imbalances are quite common in many conditions including day to day stuff. With Neuroendocrine Cancer, it can be a real challenge both at diagnostic and maintenance phases. In addition to the cancer angle, there's some strange stuff going on, inexplicable, frightening for the patient, an unwanted ingredient causing chaos!Until I was diagnosed with metastatic Neuroendocrine Cancer, I didn't have a clue about hormones - it's one of those things you just take for granted. However, hormones are vital to human health (male and female) and it's only when things go wrong you suddenly…
Histamine – NET or NOT?
Histamine is mentioned a lot in both patient groups and in literature as somehow connected with NETs, particularly with so called carcinoid syndrome (CS). In fact, various putative mediators, including serotonin, catecholamines, brady- and tachykinins, kallikrein, histamine, motilin, and prostaglandins, have been suggested as potential causative factors for the symptoms and complications associated with CS. It is generally believed that most of these tumour-derived secretory products are inactivated by hepatocytes and, therefore, only cause symptoms when they either bypass or are secreted outside of the portal vein drainage system. I wanted to focus on Histamine in this article. But what…
European Neuroendocrine Tumor Society (ENETS) 2023 guidance paper for Duodenal neuroendocrine tumours (NETs) G1–G3
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…
Experimental drug for Gastric NET – Netazepide
Gastric NETs When I wrote my post entitled "Spotlight on Gastric Neuroendocrine Neoplasms", I explained what these were with some emphasis on the association with hypergastrinemia (elevated fasting serum gastrin levels) with Type 1 and 2 gNETs being differentiated by the settings in which this occurs. This oversecretion is not the same as so called carcinoid syndrome found in other gastrointestinal NETs. Many people with a Gastric NET will already have acid reflux related issues and many will be taking medications such as proton pump inhibitors. But I was surprised to find there was not an approved targeted medication that…
A spotlight on Gastric Neuroendocrine Neoplasms
What are Gastric NENsUnlike other anatomical types, the word Gastric is used to indicate a tumour (NET) or carcinoma (NEC) in the stomach. The stomach lies at the bottom of your oesophagus and connects to the first part of the small intestine (the duodenum). Clearly a key part of the gastrointestinal system, it processes food on its journey downwards.The stomach produces strong acid. This kills many microorganisms that might have been swallowed along with the food. It also contains special chemicals called enzymes. These are important for breaking down the food so it can be absorbed by the body. After…
Proton Pump Inhibitors (…..and H2 Blockers) the NET Effect
What are Proton pump inhibitors (PPIs)? Proton pump inhibitors (PPIs) are among the most commonly used medications in the world. They reduce the production of acid by blocking the enzyme in the wall of the stomach that produces acid. Acid is necessary for the formation of most ulcers in the oesophagus, stomach, and duodenum, and the reduction of acid with PPIs prevents ulcers and allows any ulcers that exist in the oesophagus, stomach, and duodenum to heal. PPIs are prescribed to treat acid-related conditions such as: Esophageal, duodenal and stomach ulcers NSAID-associated ulcer Ulcers Gastroesophageal reflux disease (GERD) Zollinger-Ellison Syndrome…
Ever wonder what caused your Neuroendocrine Cancer?
OPINION. When you're diagnosed, you go through a whole host of emotions. It's not just the initial shock, the disbelief, the anxiety and morbid worry produced by the words "you have cancer", it's other stuff such as anger and denial. With the latter, the denial normally wears off as you finally accept the predicament.In hindsight, the anger is interesting because there can be a mixture of thoughts including "why me", "what could I have done to head this off"; and would you believe I was even angry that my diagnosis was going to affect my performance at work and even…
