The 6 E’s
An opinion postWhen I first heard of something called "The 5 Es", it struck me that I was aware of these issues and their potential effects; and I’m certain there is science to substantiate most of the content. These 5 E’s are apparently the most common ‘triggers’ for (so called) Carcinoid Syndrome. Clearly, they are not going to have the same effect on every patient e.g. I have the occasional drink of ‘Ethanol’ and I always enjoy it, I go for long exhausting walks as ‘Exercise’ and I always feel great after. I had dental treatment using ‘Epinephrine’ without any precautions before and after I…
Early diagnosis of late stage cancer
Early diagnosis of late stage cancer What a strange title for a cancer blog post! However, what a strange cancer I have. Let me explain - I was really confused in 2010 as to how I could suddenly become a stage 4 Neuroendocrine Cancer patient even though I didn't feel ill enough to see a doctor. To cut a long story short, you can read about me here. "The cancer has been growing for years" One of the common stories I hear from other patients is they were told their cancer had been growing for some years, up to 10/11/12 in…

Neuroendocrine Cancer: Diagnosing the Undiagnosed
Neuroendocrine Cancer is one of a number of "difficult to diagnose" conditions. Many types of Neuroendocrine Cancer come with an associated syndrome and these syndromes can mimic everyday illnesses. In many cases, people don't even feel ill while the tumours grow. Most types of this cancer are slow-growing but there are also aggressive versions. Although things appear to be improving in diagnostic terms, it can sometimes take years for someone to be finally diagnosed correctly and get treatment, albeit in some cases, too late for any hope of a curative scenario. It's a very sneaky type of cancer and if…
Somatostatin Analogues for Neuroendocrine Cancer: Lanreotide and Octreotide
Updated and reviewed 15th January 2025. Somatostatin Analogues are the 'workhorse' treatments for those living with NETs, particularly where certain syndromes are involved. So not just for classic NETs with Carcinoid Syndrome but also for treating the hormone overscretions caused by insulinoma, gastrinoma, glucagonoma and VIPoma (all types of pNETs) and others. They are most effective if the NETs express somatostatin receptors. They also have an anti-tumour effect but more of a slowing down of growth rather than a killing or reduction of tumour size - but there are always outliers where such effects are displayed.Somatostatin is actually a naturally occurring hormone produced by the…
Neuroendocrine Cancer – tumour markers and hormone levels
Originally published 2016, updated October 2025BackgroundSome people hear the terms "tumour markers" and "hormone levels" when they are diagnosed with Neuroendocrine Neoplasms (NENs). That might be confusing or even alarming at the time. Most people diagnosed with cancer will have had a form of medical testing at some point in their life, i.e. the sampling and testing of blood, urine, saliva, stool or body tissue. With NENs, the medical staff are just measuring the content of a 'substance' and then taking a view whether this is normal or not based on pre-determined ranges. These tests are normally done as a…
Neuroendocrine Cancer – no sweat!
I see so many questions and comments in my private group about sweating, in particular, 'night sweats' and it's prompted me to dig deeper, thus this article. When I look at a dozen decent sources of medical info, they all seem to bring up several common causes appearing on the different lists on each website I look at. I do see (so-called) carcinoid syndrome come up infrequently and perhaps the authors are lumping that in with hot flashes/flushing etc. But on authoritative NET sites (i.e. written by the NET scientific community), I do not see 'sweating' come up in the…
Rosacea – the NET Effect
Around 2001, I started noticing some issues on my nose, particularly around the creases, an issue I still experience today. It normally starts with a stinging feeling, an indication I'm about to experience some sort of inflammation. What eventually happens is something which looks like a 'whitehead' which I now know to be a 'pustule'. Sometimes there are multiples, and most are not normally bigger than 2mm, mostly smaller. These pustules nearly always disappear within a short period of time, normally after washing/showering, but they tend to leave reddish marks which eventually fade. Very infrequently, these pustules would appear on…
Serotonin – the NET effect
BackgroundI'd never heard of Serotonin until I was diagnosed with Neuroendocrine Cancer in 2010. It is frequently discussed, often with contrasting views from the respondents. One common assumption/question is that it is responsible for many things that can go wrong with Neuroendocrine Cancer patients who have serotonin-producing tumours. To a certain extent, that's true but statement such as "it's the hormones" is an easy assumption to make; or an easy answer to give in response to a complex set of circumstances. It's difficult to get a definitive answer and the science behind the behaviour of our hormones isn't really 100%…
The 5 E’s (of Carcinoid Syndrome)
The 5 Es was a good idea but the boundary was never properly defined. I don't believe it applies to all NETs and I don't believe it is confined to carcinoid syndrome Original Post Since my diagnosis, I seem to have been in a perpetual learning phase! What not to do, what not to eat, what not to read! However, early on in my experience, I came across a list of 'E' words (5 of them) which is a handy reminder for Carcinoid Syndrome patients, particularly those whose symptoms are not under control. When I say "carcinoid syndrome" in this article,…

“What are you doing this afternoon”
On 8th July 2010, I was sat in front of a secondary care consultant. I asked specifically for this consultant for two reasons, firstly, he carried out a colonoscopy some 20 months previously which turned out to be negative. Secondly, my GP had referred me to the iron deficiency anaemia clinic, and they wanted to do ….. a colonoscopy. I changed that plan because this "non-issue" was dragging on; quite frankly I wanted it to be resolved quickly, and I wanted it to be resolved in my favour - after all, in my head, I wasn't actually ill..... two months…
Please flush after use!
In the past couple of years, I've read so many stories about the quite natural act of using a toilet (.....some more repeatable than others). I think if there were a 'Bachelor of Science degree in Toiletry', I might pass with First Class Honours.I jest clearly but it's strange that such a routine activity for most can actually become quite scientific in the world of Neuroendocrine Cancer and other ailments which might be described in some scenarios as invisible illnesses.I also found myself smiling at the fact that flushing is connected with the toilet and a type of red warm feeling…
Neuroendocrine Cancer – the diarrhea jigsaw
Reviewed and updated 5th July 2024Diarrhea can be a symptom of many conditions, but it is particularly key in Neuroendocrine Tumour (NET) Syndromes and types, in particular, so called Carcinoid Syndrome but also in those associated with various other NET types such as VIPoma, PPoma, Gastrinoma, Somatostatinoma, Medullary Thyroid Carcinoma.Secondly, it can be a key consequence (side effect) of the treatment for Neuroendocrine Tumours and Carcinomas, in particular following surgery where various bits of the gastrointestinal tract are excised to remove and/or debulk tumour load.There are other reasons that might be causing or contributing, including (but not limited to) endocrine…
Pancreatic NET with carcinoid syndrome – not as common as you think
Why do I need to write about this? I've been watching confusion surrounding symptomatic pancreatic NETs for years and it never ceases to amaze me that people automatically think "carcinoid syndrome". Despite the fact that pancreatic NETs were never included in the category of "carcinoid tumours"; and despite the fact that there are at least 6 or 7 known pancreatic NET hormonal syndromes, this myth persists. Don't misunderstand me though, a serotonin secreting pancreatic NET is possible, it's just not nearly as common as it's made out in patient groups and on some websites. It's a highly unusual scenario. Why…
Neuroendocrine Cancer: My experience with Lanreotide Ipsen
On 9th December 2024, I celebrated 14 years of Lanreotide - click here to read about that. Update 11th Jan 2024. Ipsen decided to change the name for Somatuline Autogel to Lanreotide Ipsen. Clearly to distinguish its product from the generics now rolling out. Not seen similar yet for Somatuline Depot (US). My Lanreotide Experience When I was discharged from hospital following major surgery in Nov 2010, I knew I would shortly be commencing long-term monthly 'somatostatin analogue' treatment and had assumed Octreotide (Sandostatin LAR) would be the drug of choice. However, my Oncologist prescribed Lanreotide (known in the UK as…
Ignore this post about Neuroendocrine Cancer
Actually, you must share it widely, people out there will have this disease and need a diagnosis. People already out there with a diagnosis and want more awareness - so go on, ignore the post title and share it! When I was diagnosed, I wasn't feeling ill. In hindsight, I now know some of the signs were there, I just put up with them. Neuroendocrine Cancer had laid a trap for me, and I fell right into it. You see, Neuroendocrine Cancer can be very quiet and unobtrusive. It also plays the 'long game' and will sometimes take years before it's finally…
I bet my flush beats yours?
Background Neuroendocrine Tumours (NETs) can sometimes present with one or more vague symptoms which occasionally results in a lengthy diagnostic phase for some. Sure, there can be issues with doctor experience and knowledge that can add to the problem. However, some people do present with multiple vague and confusing symptoms and some people have comorbidities that have similar symptoms. Textbook diagnostics just don't make sense, sometimes even when the doctor suspects a NET i.e. classic symptoms of 'something' but with negative markers for NETs. Clearly, those are extreme cases and just like other complex diseases, diagnoses of NET can be…
Neuroendocrine Cancer: Beware But Be Aware
An awareness post from Ronny Allan BEWAREThere are a lot of scary diseases in this world. Take the lesser-known type of cancer that infiltrated my body for example - Neuroendocrine Cancer. Not only is it scary but it's also cunning, devious, misleading, and double-crossing. It likes nothing better than to play tricks on you.It will grow in your body without you knowing. It finds places to hide, mainly the small intestine, appendix, lungs, stomach, pancreas, rectum, and a host of other places. It can be fiendishly small to avoid being seen. Once it's established in the primary location (....or locations),…
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…
Neuroendocrine Cancer: If your doctors don’t suspect something, they won’t detect anything!
One of the most discussed and debated Cancer issues is late diagnosis. Cyberspace is full of disturbing stories and many different cancers are involved. Some cancers are notoriously difficult to diagnose, meaning that awareness and education needs to extend from the general population to healthcare professionals at all levels. The latter is a challenge as first-line physicians battle to deal with thousands of different conditions, many of which have similar presentations. Neuroendocrine Neoplasms have a record of being difficult to diagnose which often leads to late diagnosis. Moreover, due to their often-silent nature, a late diagnosis is often a default…
A Spotlight on NET Syndromes – Carcinoid Syndrome
What is Carcinoid Syndrome?Carcinoid syndrome (CS) is the most frequent hormonal complication accompanying neuroendocrine neoplasms (NENs) and is defined by chronic diarrhoea and/or flushing in the presence of systemic elevated levels of serotonin or its metabolite 5-hydroxyindolacetic acid (5-HIAA). Importantly, other causes of these symptoms should be considered and investigated depending on the clinical presentation. CS is predominantly encountered in patients with well-differentiated NENs (neuroendocrine tumours, NETs) of intestinal origin, followed by lung NETs, and only in a minority of patients with pancreatic, ovarian, thymic, or unknown origin NETs. The main symptoms defining CS are skin flushing, secretory diarrhoea, bronchospasm, or abdominal…
Neuroendocrine Cancer – The F Words
When I first created my blog in April 2014, I had to find some material to lead up to my 84 mile walk (at the time, it was a temporary vehicle for the single purpose of raising money for charity). An idea I had probably led to the longer term survival of this blog after people quite liked the descriptions of well known words used in NET parlance. I managed this using an A to Z list over approximately 26 days which was perfect for my timeline. I gradually renamed those early blog posts and I just noticed that the…
I woke up on World Neuroendocrine Cancer Day
1 year after 2 x surgery 5 years after 3 surgeries 10 years after surgery 15 years after first surgery It was 10th November 2010 just after midnight. I gradually woke up after a marathon 9-hour surgery - the first of what was to be several visits to an operating theatre. The last thing I remembered before going 'under' was the voices of the surgical staff. When I woke up, I remember it being dark and I appeared to be constrained and pinned down by the dozen or so tubes going in and out of my weak and battered body. …
No flushes please!
Remastered 24th Oct 2023 Original Blog 6th Sep 2014 (but talking in public about my 2010 experiences). Despite people's expectations, diagnosing Cancer isn't a two-minute job. There is a whole host of stuff to consider, and medical staff clearly want to get it 100% correct in order to plan and manage the patient's treatment. I wrote a blog on 26 July "celebrating" 4 years since diagnosis - it's worth a read, check it out by clicking here. Continuing with the 'four years on' theme, 4 years today I started my first treatment. That was a full 6 weeks after diagnosis.…
My stomach sometimes cramps my style
When planning to walk Hadrian's Wall in the north of England in 2014, I carried out a number of risk assessments (as all good Project Managers do!). In true 'Donald Rumsfeld style', I considered all the 'known unknowns' and the 'unknown unknowns'. Anybody who doesn't is either reckless or supremely confident (the latter can sometimes be the same as the former......). This major undertaking was within 4 years of my diagnosis and within two years of 3 surgeries and I was borderline stable. I wanted to get it done while I was able! As a Cancer patient, there were some…
Just got (a) shot in the buttocks
I love watching films and Tom Hanks is one of my favourite actors. He's played such a wide range of parts and I've found every single one of his films enjoyable. I think the first one I remember was 'Big' - a cracking family film for all ages. When I saw the large floor piano keyboard in Schwartz toy store in New York, I had to give it a go (video or photo to follow if I can find it!). On the opposite side of the scale, he's also been in some quite gory films such as 'Saving Private Ryan'…
Let’s Talk About NETs (#LetsTalkAboutNETs)
I do a lot of writing about NETs but I guess I've also done some talking too. Some of these talks to patient groups and healthcare professionals were recorded and I have access to those recordings. Others were not recorded but where possible and I am authorised to do so, I will attach the presentation slides. Please note videos, presentation slides, and any Podcasts are in English. I'll list some of them below for your perusal. I will keep adding them so they're all in one place. Published TalksAnn Edgar Trust - 31st August 2022I was invited by Gordon Mackay who runs…
Update: Management of Neuroendocrine Tumors
This is an excellent and positive video based overview of where we are with the Management of NETs. This is a presentation from a NET Specialist (who some of you may know) presenting to a "GI Malignancies" conference. This is therefore not only awareness of NETs, it's also some good education for non NET GI experts who may only know the very basics. Useful for patients too! I met Dr Strosberg in Barcelona (ENETS 2017) and thanked him for his presentational and scientific paper output which I often use in my articles. The classification picture is good as it explains…
ASCO 2017 – Let’s talk about NETs #ASCO17
ASCO (American Society of Clinical Oncology) is one of the biggest cancer conferences in the world normally bringing together more than 30,000 oncology professionals from around the world to discuss state-of-the-art treatment modalities, new therapies, and ongoing controversies in the field. As Neuroendorine Tumors is on a roll in terms of new treatments and continued research, we appear to be well represented with over 20 'extracts' submitted for review and display. This is fairly complex stuff but much of it will be familiar to many. I've filtered and extracted all the Neuroendocrine stuff into one list providing you with an…
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…
