Neuroendocrine Neoplasms: A riddle wrapped in a mystery inside an enigma
The riddle.For many years, I've been reading and blogging about Neuroendocrine Neoplasms, NENs for short. NEN is a relatively new term which came after my diagnosis. Nomenclature is still evolving and there is always something to learn. It's also true to say the term 'Neuroendocrine Neoplasms' is the same as saying 'Neuroendocrine Cancer'. These neoplasms are cancers that begin in specialised cells called 'neuroendocrine cells'. Neuroendocrine cells have traits similar to those of nerve cells and hormone-producing cells, particularly the latter. In face one NET specialist said "While the name “neuroendocrine” implies that these tumors involve both nerve cells and…
Weight – the NET Effect
Foreword After my first surgery in November 2010, I came out at the lightest weight I had been for many many years (10st 7lbs (147lbs)). 6-7 weeks later I went back to work and people privately commented that I shouldn't be at work, I looked too frail and ill. Perhaps it was because my suit no longer fitted me properly! That was an expensive year because I had to buy new suits, a requirement of my employment. Fast forward 4 years, I had to buy some more suits as my weight was going back on. Fast forward 14 years and…
Diabetes – The NET Effect
Updated January 2026Originally published September 2018. My chest infection is now settled, as too is the excitement and apprehension behind my first ever Ga68 PET - the outcome of that is still a work in progress. Earlier this year, my thyroid 'lesion' on watch and wait was given a 'damping down' with the prescription of a thyroid hormone supplement but I await a re-ignition of that small bush fire downstream. Bubbling behind the scenes and clamouring for attention is the spiking of my blood glucose test results and I was very recently declared 'at risk' for diabetes with a score…
The Syndromes of Neuroendocrine Cancer – Early Signs of a Late Diagnosis
There are some curious things about Neuroendocrine Cancer (NETs elsewhere in the text on the basis that a hormonal syndrome is extremely rare in Neuroendocrine Carcinoma (NEC)). One of them is that it can very often exhibit one or more vague symptoms collectively known as a 'syndrome'. Syndrome is an apt word to describe these complications as the most general meaning in medical terms is a group of symptoms that together are characteristic of a specific disorder or disease". Having a syndrome can often be the difference between having a 'functional' condition or a non-functional' condition. This frequently makes NET …
Carcinoid Syndrome – chicken or egg?
We’ve all heard the age-old question about the chicken and the egg? Scientists claimed to have 'cracked' the riddle of whether the chicken or the egg came first. The answer, they say, is the chicken. Researchers found that the formation of egg shells relies on a protein found only in a chicken's ovaries. Therefore, an egg can exist only if it has been inside a chicken. There you have it! On a similar subject, I'm often confused when someone says they have been diagnosed with 'Carcinoid Syndrome' but not one of associated 'Neuroendocrine Tumours' - my instinct says that is…
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…
A Spotlight on Lung Neuroendocrine Neoplasms
WHO Classification of Tumours, 5th Edition, Volume 5: Thoracic Tumours The aim of this spotlight is to provide a summary of the latest information on Lung Neuroendocrine Neoplasms (NEN) including the latest terminology, epidemiology data, and guidelines. This follows the publication of the Thoracic WHO classification 5th edition (2021): terminology and criteria for neuroendocrine neoplasms (Blue Book). This book has been anticipated to see if the panel compiling this follows the lead of the Gastroenteropancreatic Neuroendocrine Neoplasms (GEPNEN) editions issued in 2017 (Endocrine) and 2019 (Digestive systems) by removing the antiquated misnomer term ''Carcinoid" in line with the recommendations made…
Paraneoplastic Syndromes – the NET Effect
Although several hypotheses have been proposed regarding the pathogenesis of Paraneoplastic Syndromes (PNS), the precise mechanism that leads to the development of PNS remains largely unknown. In simple terms, pathogenesis means "the manner of development of a disease". Disclaimer. I read widely and noted various papers where there was clearly confusion about the classification of paraneoplastic in relation to Neuroendocrine Neoplasms. Some papers grouped known Neuroendocrine Tumour hormonal syndromes in, but others were more specific by filtering these into ectopic scenarios. I eventually filtered out papers based on the expertise of the authors and the common threads running in each…
Neuroendocrine Cancer – it can be ‘smoke and mirrors’
In a previous life, I used the term 'smoke and mirrors' quite a bit. I was used to dealing with many different types of people, some who wanted something, some who wanted to buy or sell something. Most of the time it was overt but the devil was usually in the detail. Sometimes there was an element of 'covertness' or a 'hidden agenda'. It was always tricky working out the details of the hidden agenda and sometimes it was only known when it was too late. Some of you will already be seeing where I'm going with this line of thinking -…
Somatostatin Analogues and delivery methods in the pipeline
NOTE - THIS IS IN NEED OF AN UPDATE AND IS ON MY LIST OF THINGS TO DOThis is my live blog post covering new developments in the area of new Somatostatin Analogues and new delivery systems. AbstractAs most of you will be aware, there are currently two main types of Somatostatin Analogues (SSA) in use for the treatment of mainstream Neuroendocrine Tumours (NETs) - Octreotide and Lanreotide. You can click on the links for information on both of these well-known NET treatments. This post will focus on the not so well known and anything in the pipeline including different delivery…
