Neuroendocrine Cancer: Diagnosing the Undiagnosed

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…
Neuroendocrine Cancer – tumour markers and hormone levels

Neuroendocrine Cancer – tumour markers and hormone levels

Originally published 2016, updated October 2025 Background Some 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…
Happy Thanksgiving

Happy Thanksgiving

I have been posting this every year on last Thursday in November and I kept forgetting that other countries other than USA (and Territories of the United States) also do Thanksgiving but mostly on different dates. This includes (but is probably not limited to): Canada, Brazil, Grenada, Liberia, Saint Lucia, Leiden (Netherlands), Norfolk Island (Australia).   I hope you all had/have a great Thanksgiving Day! Turkey and Sleep Now ........ I hate to stereotype but I guess a lot of you might be eating turkey on Thanksgiving Day?  No Thanksgiving is complete without a turkey at the table (... so I'm told!). …
Palliative Care – it might just save your life

Palliative Care – it might just save your life

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…
Serotonin – the NET effect

Serotonin – the NET effect

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 E’s (of Carcinoid Syndrome)

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,…
Neuroendocrine Cancer – the diarrhea jigsaw

Neuroendocrine Cancer – the diarrhea jigsaw

Reviewed and updated 5th July 2024 Diarrhea 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, Gastrinoma, Somatostatinoma, Medullary Thyroid Carcinoma, PPoma. 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…
The Syndromes of Neuroendocrine Cancer – Early Signs of a Late Diagnosis

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 …
Neuroendocrine Cancer:  My experience with Lanreotide Ipsen

Neuroendocrine Cancer: My experience with Lanreotide Ipsen

On 9th December 2025, I celebrated 15 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).  Please note the remainder of this blog covers Lanreotide Ipsen, generics are covered here.  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…
I bet my flush beats yours?

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 – Horrible Hormones

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…
I woke up on World Neuroendocrine Cancer Day

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. …
A spotlight on 5-HIAA

A spotlight on 5-HIAA

Background. It's important to note that not every type of Neuroendocrine Neoplasm will get the same tests due to the heterogenous nature of this cancer type. Some are more specific than others.  A wide range of tests may be necessary at diagnosis if the type of NET is not clear. This post will cover one of the main tests to check for a common type of Neuroendocrine Tumour (NET) that is known to secrete excess amounts of the hormone Serotonin leading to symptoms indicative of Carcinoid Syndrome.  These tumours are often labelled using the antiquated and misnomer term ‘Carcinoid Tumour’ but more…

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…
