Tag: Carcinoid syndrome

A syndrome connected with (mainly) serotonin secreting tumours in certain locations (mainly small intestine, lung, stomach, appendix, rectum). The key symptoms include diarrhoea, flushing of the skin (particularly the face), stomach cramping, heart problems such as palpitations, and wheezing. The syndrome is actually caused by the release of a number of hormones, in particular Serotonin, Bradykinin, Tachykinin (Substance P), Histamine, and Prostaglandins.

Carcinoid syndrome occurs when biologically active amines and peptides enter the systemic circulation escaping the first pass metabolism of the liver. Normally, these bioactive products are inactivated by the liver. However, in cases of neuroendocrine tumors with liver metastasis, either these bioactive products are directly released into the systemic circulation, or they escape inactivation due to deranged liver function.

Awareness, Patient AdvocacyAdvanced neuroendocrine cancer, Carcinoid syndrome, Paraganglioma, Pheochromocytoma

When I was diagnosed, I didn’t even feel ill. It was therefore a bit of a shock being told I had metastatic cancer, advanced enough to kill me without treatment. It was hiding But it did make me think back to some minor irritants, or to be accurate what I thought were minor irritants, things that I could not explain, things that I did not think were serious enough to speak to a doctor. And what would this doctor have said at the time? I was never misdiagnosed because I was never diagnosed with anything that wasn’t already there and documented.…

D Day I was 54 years and 9 months old at diagnosis on 26th July 2010. For the first few months, I had no idea what the outcome would be. What I did know at the time, given the final staging and grading, in addition to the other damage that was accumulated via various tests, checks, and scans; is that my body had been slowly dying. Without intervention I may not be here now to tell you this tale and who knows what would be listed on my death certificate. It’s amazing to think something that would eventually kill me…

It's only a couple of weeks since I celebrated my 15th year since diagnosis of metastatic small intestine Neuroendocrine Tumour (NET) at Grade 2. Thinking back to that period of my life, I'm happy but also slightly amazed to be celebrating such a long milestone having been diagnosed with cancer at Stage IV. I think it's a sign of many things, including but not limited to, early intervention by inquisitive healthcare professionals following vague symptoms, early access to a NET multidisciplinary team (MDT). Of course, human resilience must also be a factor. I didn't take this diagnosis lying down, I…

When you manage a large support group, you see a lot of posts. Many of them highlight a lack of knowledge about the heterogeneity of Neuroendocrine Neoplasms. The issue is not always with those answering the question but often it is the person asking the question. Sometimes intervention is needed to focus responses. So, what are the key issues? Read on..... If you read any authoritative source on this cancer, it will normally begin with “Neuroendocrine Neoplasms (NENs) are heterogeneous tumours ………….” “Heterogeneous” means consisting of dissimilar parts or elements, essentially meaning “mixed” or “diverse,” but I used the term…

15 years today, and before I was formerly diagnosed, I had a blood test done. And it was a fairly insignificant event, as a precaution, as a "just in case" check after telling a nurse in my GP surgery that I thought I'd lost some weight. The form she gave me sat in my in-tray for a couple of weeks, I was far too busy at work for blood tests. I didn't even feel ill! Fortunately, I did eventually get the test done on 11th June 2010 and and here we are today! Check out the video where I talk…

An opinion post When 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…

The terms functional and non-functional come up a lot in documents describing Neuroendocrine Cancer. They also feature highly in patient groups. But what do these terms actually mean? Functional / Non-FunctionalNeuroendocrine Tumours are treatable for most but the difficult part can be arriving at a diagnosis. Moreover, some Neuroendocrine Tumours (NETs) can be silently growing and as they grow slowly, the 'silence' can go on for some years. Even with a syndrome, the root cause can remain disguised as the symptoms are similar to many day-to-day illnesses. There can be the odd exception but in general terms, NETs are either functional (with…

After years of avoiding pancreatic enzyme replacement therapy (PERT) since a 2010 diagnosis, I finally asked for some on a trial basis at the end of 2017. To be honest, for some time, I thought they were really only needed in the NET world for those with pancreatic issues (pNETs).

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…

A fairly common disposition of Neuroendocrine Neoplasms is a primary with associated local/regional secondary's (e.g. lymph nodes), and often with liver metastases. Technically speaking, the liver is distant. However, many metastatic patients appear to have additional and odd appearances in even more distant places, including (but not limited to) the extremities and the head & neck. Certain things are known about the behaviour of Neuroendocrine Neoplasms (NENs) (a term for Neuroendocrine Tumours and Neuroendocrine Carcinoma) and specialists will be analysing many factors when working out the type of NEN and how it might behave.

Edited and refreshed 13th January 2026 There's a lot of inaccurate and out-of-date information out there. Some are just a lack of understanding, and some are caused by out-of-date websites. Often the problem is a result of patient forum myth spreading exacerbated by poor moderation in the groups concerned. Some can only be described as propaganda. Some of it even comes from uninformed doctors and bizarrely and disappointingly from NET advocate organisations. All the graphics below contain links to relevant blog posts.

Surgery can sometimes be a tough call (......to cut or not to cut?) I see a lot of patients asking very specific surgical questions in my group (and also direct messages to me). Some ask outright "should I get surgery" and that is a very difficult question for anyone to ask, and should be something directed at their own doctors. If they lack trust in their doctors, they should seek a second opinion. All I can do, along with others in my private patient group, is to let these people know about our own experiences.

From day 1 of my diagnosis, I knew my liver was going to need some attention, but I had always known that total removal of all tumours would not be possible - the diagnostic scan confirmed I had an incurable disease. This critical organ did in fact produce the biopsy confirming Neuroendocrine Cancer. The early scans indicated multiple liver lesions and an Octreotide scan reported several with quite avid isotope activity. However, as you can see from my clinical history, they first stabilised my syndrome via daily Octreotide so my tumours were subdued ready for major surgery which took…

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.

Disclaimer: Educational and advocacy content only. Not a substitute for medical advice. 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 over secretions 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…

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…

AwarenessCarcinoid crisis, Carcinoid heart disease, Carcinoid syndrome, Carcinoid tumour, Carcinoma, Metastatic Neuroendocrine Cancer, Neoplasm, Neuroendocrine, Neuroendocrine cancer, Neuroendocrine carcinoma (NEC), Neuroendocrine tumour (NET), Noid

A quick primer on the word 'CARCINOID'. It originates from the term 'Carcinoma-like'. 'CARCIN' is a truncation of Carcinoma (by definition cancerous or malignant tumour). 'OID' is a suffix meaning 'resembling' or 'like'. This infers that Carcinoid cannot be a truly malignant tumour - thus the confusion. The most worrying connotation of the use of the word ‘Carcinoid’ is the belief that they all have benign clinical and biological behaviour. That is dangerous thinking which could end up killing people. There is now widespread use of the term Neuroendocrine Tumours (NETs) and this is based on the latest classification scheme pushed…

D Day I was 54 years and 9 months old at diagnosis on 26th July 2010. For the first few months, I had no idea what the outcome would be. What I did know at the time, given the final staging and grading, in addition to the other damage that was accumulated via various tests, checks, and scans; is that my body had been slowly dying. Without intervention I may not be here now to tell you this tale and who knows what would be listed on my death certificate. It’s amazing to think something that would eventually kill me without intervention,…

Living with Neuroendocrine CancerAntidepressant, Anxiety, Carcinoid syndrome, Diabetes, Flushing, Hyperhidrosis, Hyperthryroidism, Hypoglycemia, Menopause, Neuroendocrine cancer, Night sweat, Pheochromocytoma, Sleep hyperhidrosis, Sweating

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

Rosacea – the NET Effect

Patient Advocacy, The NET Effect SeriesCarcinoid syndrome, Flushing, Rosacea

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…

Update February 2026. Before you read this, please note: Why Practice Is Changing Faster Than the Guidelines Modern peri‑operative management for neuroendocrine tumours is evolving rapidly, and several factors explain why clinical practice in some expert centres has moved ahead of formal guidelines: 1. New evidence challenges long‑held assumptions Recent surgical series — most prominently from OHSU Portland USA — show that prophylactic octreotide does not reliably prevent carcinoid crisis and that crises behave more like distributive shock, responding better to vasopressors than to somatostatin analogues. This directly contradicts decades of dogma. 2. Guidelines update slowly by design Bodies such…

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…

On 26 July 2010, had you said I'd be writing this 14 years later, I would have said no.I was diagnosed on 26th July 2010. However, as things progressed, as treatment was administered, and as I got used to living with Neuroendocrine Cancer, I eventually became more confident about living longer than I initially thought. 10 years was a bit of a stretch target, I guess it can be more elasticated than you initially think. Think great doctors, better treatments, better guidelines and sprinkle some luck on top. Some might say attitude helps but clearly scientific proof might be lacking…

When you've been diagnosed with cancer at an incurable stage, certain words start to mean more. Take 'palliative' for example. Before I was diagnosed, I had always associated the word 'palliative' with someone who had a terminal disease, and this type of care was to make the final days/weeks as comfortable as possible. So, it was a bit of a shock to find out in 2010 that my treatment was palliative in nature. However, I'm still not dead and I'm still receiving palliative care. Go figure! The answer is simple - the cancer story is changing. What was once feared…

Update 4th September 2024. I have been informed by a third party and trusted source that this upgrade to Lanreotide Ipsen injection device which I published in 2022, will not happen. Apparently, the project announced in 2022 never really got off the ground. My own guess is that Ipsen's business case expenditure was too much risk given the rise of the generic Lanreotide meds around the same time, i.e. the return of investment (ROI) would not be recouped.I do not understand why Ipsen did not offer a lower price to remain competitive in UK and elsewhere. It makes me think that…

Background to why I created this blog post. For many years, I've read numerous comments and posts where people mention hives (full medical term urticaria). As far as I know, this is an issue that has never bothered me all of my life ...... until recently. I've never had any allergies other than certain cats and dogs (....I guess there might be a connection there). I'm currently taking an anti-histamine tablet each day until the issue resolves. My normal reaction to these changes is to research, so here is my research! The response in patient groups to questions about hives…

Background I'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 Tumour (NET) 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…

The 5 Es was a good idea but the boundary was never properly defined.

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.

I didn't expect to be here but I am I was diagnosed with metastatic Neuroendocrine Tumours (NETs) on 26th July 2010. Until I arrived at my 5th anniversary, I hadn't thought much about how (or if) I should mark these occasions. I never thought I would dwell on such things as 'Cancerversaries' but I now totally get why many patients and survivors do. There are several types of 'Cancerversary' that for some, could trigger a mix or range of emotions including gratitude, relief and fear of cancer recurrence or growth.

The Perfect Storm of Neuroendocrine Cancer by Ronny Allan, featured by Neuroendocrine Cancer UKAs featured by Neuroendocrine Cancer UK (formerly NET Patient Foundation)It's well known that Neuroendocrine Cancer can often be a very difficult to diagnose condition. However, what is less well known is the impact it has on those who are diagnosed. I'm one of the lucky ones, even though I still ended up with distant metastases. It does feel odd to say that having distant metastasis is lucky!I consider my diagnosis to have been incidental as they were not investigating cancer - I suspect that's the route for…

Opinion. First published in January 2016. Social Media is currently full of 'Dry January' articles and of course many charities will benefit as people will be motivated if they are abstaining from alcohol for a good cause. Nothing wrong with that and no doubt some individuals will also see it as a way to cut down or at least lessen the effects of a very wet December! I've never been a big drinker but I do like the odd beer now and then.

Small Intestine NETs The latest European Neuroendocrine Tumor Society (ENETS) 2024 guidance paper for the management of well-differentiated small intestine neuroendocrine tumours As someone who was diagnosed with metastatic small intestine NETs in 2010, I've clearly written many words about my own experience and how I was treated. However, I've also researched extensively about these issues including previous guidelines for the management of these common but complex tumours. They are mostly indolent, but they can be aggressive; they are legendary spreaders, often in silence. They can cause damage before and after diagnosis, and it is these tumours that are predominately…

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…

If you read any authoritative source on this cancer, it will normally begin with "Neuroendocrine Neoplasms (NENs) are a group of heterogeneous tumours .............". The term heterogeneous means diverse in character or content; or a structure with dissimilar components or elements. This is not surprising as these tumours are found in Neuroendocrine cells throughout the vast majority of the human anatomy. And yet, when you look at many hospital/healthcare sites, advocate organisation sites, and cancer information sources not maintained by Neuroendocrine Cancer scientists or specialists, you might start to think there is just one big type of NET and only…
