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 the different facets of NETs and how NETs are classified and categorised in a general way – not seen it done this way before.   Slightly out of date as it does not adequately convey the possibility of a well differentiated high grade recently classified by the World Health Organisation – read more here.

Amazingly it is delivered without using the word ‘carcinoid’ other than in reference to syndrome, indicating it can be done and is something also being reflected in all my posts to ensure they are up to date with the latest nomenclature.  It’s also a good example for GI doctors as this branch of medicine is often involved in NET diagnostics and surveillance.

Excellent update of all the trials which have introduced treatments in the last decade.

NETwork with Ronny © – Community Newsletter SEPTEMBER 2017

Hi NETworkers!

Welcome to my monthly ‘Community’ newsletter. This is September 2017’s monthly summary of Ronny Allan’s Community news, views and ICYMI (in case you missed it!).

NET News

The following news items may be of interest:

 
  • The European Commission (EC) approved Lu-177 Lutathera (PRRT) on 28 Sep.  This is the first time the drug has ever been approved, despite being in use for  over 10 years.  In USA, the FDA gave a date of 28 Jan 2018 for its decision to approve or not.  Read more here.
 
  • The European Commission approved the use of XERMELO (telotristat ethyl) for use in Carcinoid Syndrome diarrhea not adequately controlled by somatostatin analogues. Read more here.
 
  • The US FDA approved an add-on indication for Lanreotide (Somatuline) for treatment of carcinoid syndrome, adding when used, it reduces the frequency of short-acting somatostatin analogue rescue therapy (….. ergo Octreotide).  Read more here.
 
  • GA-68 PET (NETSPOT) continues to roll out across the USA, see CCFs latest list by clicking here.

 

 
  • The WEGO Health Finalists were announced on 25 Sep and I’m through to the finals in all 3 awards which you nominated me for. Many thanks for the support!  I posted this info here.

Blog Site?  

Due to the vagaries of Facebook inner workings, some of these may not have even shown on your timeline.  So, ICYMI …….here’s a summary with links, includes updated blogs. You can actually sign up to receive my blog articles direct to your inbox when published – subscribe here.

 
 
 
  • The Invisible NET Patient Population.  Centred on the issue of a cohort of as yet undiagnosed people with NETs; or have been labelled with another cancer; or have been told their cancer is benign and therefor not recorded.
 
  • The WEGO Health Finalists were announced on 25 Sep and I’m through to the finals in all 3 awards which you nominated me for. Many thanks for the support!  I posted this info here.

 Other Activity

September was a slower month in ‘new’ blogging terms mainly due to personal activities (holiday) and the consequences of being ‘contactable’ by a large internet footprint! Striking a balance remains difficult, I’m keen to support and advocate but as a patient, I also need my own time.  I’m currently seeing a trend of low ‘new’ blog months, mainly due to external projects and a continuous stream of offline messages from patients (more on this later) – my strategy is constantly under review.  However, despite a low month for brand new blogs, I still managed to break through 20,000 views for the 4th month in a row…….. Thank you all so much for the support.

Please join my 2017 awareness campaign event here (select ‘Going’)

I continue to receive a steady flow of private contacts, mainly from patients seeking information.  I don’t have an issue with private contact but please note my disclaimer.  Please also note that I cannot accept telephone calls on a one to one basis.  Also, the number of non-patients contacting me for other reasons (mainly to help with something) continues to grow and this is producing some great publicity and awareness.

Awareness Activity in September 2017

New Audiences for NET Cancer.  From Day 1, I said it was my aim to find new audiences for NETS rather than just share stuff within our own community.

  • Article features.  I was featured in a well shared and positive article entitled A revolution in the treatment of Neuroendocrine Tumors. A very positive look at the new treatments coming through. I didn’t agree with some of the content but ‘hey ho’ I cannot control what others write.  You can check out the article by clicking here.
  • Twitter.
    • I took part in a patient chat on twitter where I was able to contribute to some general cancer questions.  It was attended by many patient advocates representing many different conditions. The taking part in these activities is time-consuming and hard work but it does allow me to grow as a general patient advocate and to occasionally mention “Neuroendocrine Cancer” spreads awareness to new audiences.  A summary of the conversation can be found here.
    • I’m ‘extremely’ active on twitter and I find a lot of my research stuff there. I also use it to support other conditions and it’s mostly returned (i.e. others help with NET awareness and are made aware of NETs in the process).  In Sept, I tweeted 109 times on my personal account which lead to almost 75,000 views.  I was mentioned 78 times by other tweeters and gained 68 new followers.  My tweet “Ignore this post” remains the most tweeted article about NETs ever posted on twitter.  Check it out – click here.

  • Daily Newsletter from my twitter feed (Nuzzel).  There is so much on twitter that I could swamp the community Facebook site so I started a twitter newsletter via an app called Nuzzel which seeks out stuff I normally like. Click this link and sign up if you think this is something you’d be interested in receiving – you don’t need to have a twitter account to read, just sign up with an email.  Currently 336 subscribers – up 12% on last month.

  • WEGO. I continue to be featured by ‘external’ organisations such as WEGO and my PODCAST is reaching new audiences – click here.  The recent awards will continue to showcase my work which has the effect of spreading Neuroendocrine Cancer awareness to NEW audiences in addition to enriching my experience as a Patient Leader.  WEGO is a fantastic organisation!

  • Macmillan Cancer Support.  I’m proud to be a ‘Voice’ and ‘Community Champion’ on the Macmillan Cancer Support Forum.  In addition I help ‘outliers’ from the NET community there. There are only 27 champions for a site supporting hundreds of thousand patients – it’s a community of communities.  I’ll be reporting more on this in the coming weeks.  This is the biggest cancer support organisation in the UK and I’m intent on developing relationships with various departments in this fantastic organisation.  On August 30th, one of my blogs made their “top picks” generating some NET awareness – check out Living with Cancer – 6 tips for conquering fear They have recently agreed to feature NETs on 10 Nov 17.
that’s me in the centre
  • Cure Magazine.  I’ve been accepted as a ‘Cure Today’ contributor which means my articles will get a wider distribution than they do now.  I’ve not contributed yet but clearly they will be posted on all my social media outlets for you to read.  Cure Magazine has a readership of 1 million.  Click here to read more.

Speaking Engagements

  • On 5th October, I’ve been invited to speak for around an hour at the Cardiff (South Wales) NET Patient meeting (moved from July due to forecast low attendance)  Things are starting to happen in this area and I already know their NET Specialist Dr Mo Khan who is working hard on behalf of patients.  I’m really looking forward to visiting and talking to this group.

Writing and other types of Engagement (external) – watch this space as I’m working on quite a few projects concurrently.  I’m currently in a pool of patients who may be featured in a UK national, fingers crossed.

Social Media and Stats

Blog Milestone.  In September, I’m very close to 380,000 views! Thank you all so much Keep sharing! On track for 400,000 by end of the October.

Facebook Milestone.  I would love to achieve 6000 followers by the end of 2017 but this will be a challenge.  The Facebook page is now my biggest outlet for awareness and education so please please please recommend this page to anyone you think would be interested.

Thanks for your great support in September.  Onwards and upwards!

NETwork with Ronny © – Community Newsletter AUGUST 2017

Hi NETworkers!

Welcome to my monthly ‘Community’ newsletter. This is August 2017’s monthly summary of Ronny Allan’s Community news, views and ICYMI (in case you missed it!).

NET News

The following news items may be of interest:

  • PRRT takes a step forward to being formally approved in USA. FDA acknowledges receipt of revised application for approval.  Click here.
  • However, in UK, there is a threat that PRRT won’t be approved despite a positive recommendation by the scientific committee of the European Medicines Agency (EMA).  Advanced Accelerator Applications (AAA), the manufacturers of Lu-177 Lutathera for use on PRRT, has had to respond to the UK’s drug approver NICE’s negative recommendation.  Read more here.
  • GA-68 PET (NETSPOT) is still rolling out across the USA, see CCFs latest list by clicking here.
  • Ipsen launches the Brazilian version of ‘Living with NETs’ website.  Click here.  (See the English language version – click here).

What’s happening on my Blog Site?  

A quiet month.  Due to the vagaries of Facebook inner workings, some of these may not have even shown on your timeline.  So, ICYMI …….here’s a summary with links, includes updated blogs.

  • The Invisible NET Patient Population.  My latest published blog and received some great viewing figures (and this continues).  Controversial for some but backed up by facts.
  • NETs – not as rare as you think. An older post with some tweaks.  Again, controversial for some but backed up by facts.
  • Carcinoid vs Neuroendocrine – One of my most controversial posts – this is an older post which previously had an element of sitting on the fence. I jumped off the fence following some further research and period of reflection.  I was happy with some of the positive comments I subsequently received on this post.
  • Steve Jobs.  An updated version with some new research timelines added.  This post continues to receive hits daily even when I’m not sharing.  Most of the hits are from people searching and find my article online, an indication of the interest Steve Jobs still has today.  And many of the hits are NEW audiences.
  • NETwork with Ronny © – Community Newsletter JULY 2017.  My July 2017 newsletter ICYMI.
  • Your favourite posts.  All posts with viewing figures above 2000.

Misc Blog Stuff

  • There’s a lot of chatter about use of the word ‘fight’ in cancer parlance but many people are misrepresenting the word’s multiple meanings as per the most eminent English language dictionaries.  As for me, I’m ‘sticking to my guns’ on the subject.
  • I got some great comments on my monthly Lanreotide ‘butt dart’ post.  Feel free to add questions.  I may know some of the answers and cannot promise answers from Ipsen due to their regulatory arrangements but I will try!  Check out the discussion here …… ‘click here’.
  • My notification about the Ipsen HomeZone (or equivalent services within your own country) got an interesting response.  Since then many others have taken advantage by contacting Ipsen or their specialist asking about the service.  This has also led to feedback about the similar schemes from Novartis for Octreotide.  I’m happy that my post has provided publicity to services which help patients.  Read my post At Home with Lanreotide by clicking here.

Other Activity

August was a slower month in ‘new’ blogging terms mainly due to personal activities and the consequences of having a large internet footprint! Striking a balance is becoming more difficult.  I’m seeing a trend of low ‘new’ blog months, mainly due to external projects and a continuous stream of offline messages from patients (more on this later).  Also, I’ve been suffering with minor right hip pain but now seeing improvements working with a physiotherapist.  However, despite a low month for brand new blogs, I still managed to make the second highest monthly views ever……..Thank you all so much for the support.

Please join my 2017 awareness campaign event here (select ‘Going’)

I continue to receive a steady flow of private contacts, mainly from patients seeking information.  I don’t have an issue with private contact but please note my disclaimer.  Please also note that I cannot accept telephone calls on a one to one basis.  However …..the number of non-patients contacting me for other reasons (mainly to help with something) continues to grow and this is producing some great publicity and awareness.

By the time you read this update, the nominations and endorsements for the 2017 WEGO Health Awards will be closed.  If you remember last year, I made it to the final in two categories of Blog and Community, and then won the latter.  I should find out if I made the finals by the middle of September. Fingers crossed!  Many thanks to those who took the time and trouble to vote for me.

NETwork with Ronny © – Community Newsletter JULY 2017

 

Hi NETworkers!

Welcome to my monthly ‘Community’ newsletter. This is July 2017’s monthly summary of Ronny Allan’s Community news, views and ICYMI (in case you missed it!).  July 26th was the ‘Cancerversary‘ of my diagnosis – I’m still here after 7 years and I’m apparently a veritable newbie!  There’s some great comments on my ‘I’m Still Here’ post – check them out … ‘click here’

NET News

The following news items may be of interest:

  • Telotristat Ethyl (Xermelo) takes a step forward to being approved in Europe. Click here.
  • PRRT takes a step forward to being approved in USA.  Click here.
  • Ipsen launches the German version of ‘Living with NETs’ website.  Click here.

What’s happening on my Blog Site?  

As per above, a quiet month.  Due to the vagaries of Facebook inner workings, some of these may not have even shown on your timeline.  So, ICYMI …….here’s a summary with links, includes updated blogs.

There’s a lot of chatter about use of the word ‘fight’ in cancer parlance but most people are misrepresenting the word’s multiple meanings as per the most eminent English language dictionaries.  As for me, I’m ‘sticking to my guns’ on the subject.

I got some great comments on my monthly Lanreotide ‘butt dart’ post.  Feel free to add questions.  I may know some of the answers and cannot promise answers from Ipsen due to their regulatory arrangements but I will try!  Check out the discussion here …… ‘click here’

NET Cancer Blog Activity

July was a slower month in ‘new’ blogging terms mainly due to holiday.  I’m seeing a trend of low ‘new’ blog months, mainly due to external projects and a continuous stream of offline messages from patients.  Also, I’m still suffering with minor pain which has decided to move to my right hip (hopefully localising where the real problem is).  Physiotherapist appointment is next week.  However, despite a low month for brand new blogs, I managed to totally smash my monthly blog view record (after smashing it last month too!)  ……..Thank you all so much for the support.

I continue to receive a steady flow of private contacts, mainly from patients seeking information.  I don’t have an issue with private contact but please note my disclaimer.  Please also note that I cannot accept telephone calls on a one to one basis.  The number of non-patients contacting me for other reasons (mainly to help with something) continues to grow and this is producing some great publicity and awareness.

I’ve been nominated for the 2017 WEGO Health Awards in three categories so far, Blog, Patient Leader Hero and Lifetime Achievement.  If you remember last year, I made it to the final in two categories of Blog and Community and won the latter.  A vote for me is a vote for Neuroendocrine Cancer awareness. VOTE HERE PLEASE

Click on ‘Endorse Ronny Allan’.  It defaults to ‘Blog’ but the other two are there via the drop down menu.  Thanks, I cannot get to the finals without the votes.

Awareness Activity in July 2017

New Audiences for NET Cancer.  From Day 1, I said it was my aim to find new audiences for NETS rather than just share stuff within our own community.

  • I’m ‘extremely’ active on twitter and I find a lot of my research stuff there. I also use it to support other conditions and it’s mostly returned (i.e. others help with NET awareness and are made aware of NETs in the process). There is so much on twitter that I could swamp the community Facebook site so I started a twitter newsletter via an app called Nuzzel which seeks out stuff I normally like. Click this link and sign up if you think this is something you’d be interested in receiving.  Currently 269 subscribers – up 12% on last month.
  • I continue to be featured by ‘external’ organisations such as WEGO and my PODCAST is reaching new audiences – click here.  Other irons are in the fire but unable to bring you firm news just yet.
  • I’m proud to be a ‘Community Champion’ on the Macmillan Cancer Support Forum helping outliers from the NET community there. I’ll be reporting more on this in the coming weeks.  This is the biggest cancer support organisation in the UK.
  • I’ve been accepted as a ‘Cure Today’ contributor which means my articles will get a wider distribution than they do now.  I’ve not contributed yet but clearly they will be posted on all my social media outlets for you to read.  Click here to read more.

Speaking Engagements

  • On 12 July, I delivered a ‘patient view’ presentation to Ipsen (UK) which was well received.
  • On 5th October, I’ve been invited to speak for around an hour at the Cardiff (South Wales) NET Patient meeting (moved from July due to forecast low attendance)  Things are starting to happen in this area and I already know Dr Mo Khan who is a NET specialist working hard on behalf of patients.  I’m really looking forward to visiting and talking to this group.

Telotristat Ethyl (XERMELO®) – an oral treatment for Carcinoid Syndrome Diarrhea not adequately controlled by Somatostatin Analogues

Telotristat Ethyl is an extremely significant introduction to the treatment of Carcinoid Syndrome diarrhea. It’s the first addition to the standard of care in more than 16 years and the first time an oral syndrome treatment has been developed.  The drug was previously known as Telotristat Etiprate but was changed to Ethyl in Oct 2016. ‘Etiprate’ was previously a truncation of ‘ethyl hippurate’.  The brand name is XERMELO® 

UPDATE MARCH 2018 

The March 2018 issue of Clinical Therapeutics provides the first report of the effects of XERMELO on changes in weight in patients with neuroendocrine tumors (NETs) and carcinoid syndrome that participated in the TELESTAR study. You have to remember that XERMELO is approved for those with carcinoid syndrome diarrhea not adequately controlled by somatostatin analogues (author’s note – i.e not for diarrhea caused by (say) side effects of surgery).

Of the 120 patients with weight data available, up to 32.5% of patients treated with XERMELO experienced significant, dose-dependent weight gain (≥3% from baseline). Only 5.1% of patients on placebo experienced weight gain. Importantly, patients with weight gain experienced improvement in carcinoid syndrome control, as seen in reduction of bowel movement frequency and in parameters of nutritional status associated with positive changes in patient-reported outcomes compared with patients with stable weight or weight loss. Those patients also experienced reduced u5-HIAA levels. Patients with weight gain also experienced fewer serious adverse events than patients with stable weight or weight loss.

(see link below)

Who is the drug for?

The drug may be of benefit to those whose carcinoid syndrome diarrhea is not adequately controlled by somatostatin analogues (Octreotide/Lanreotide). It doesn’t replace somatostatin analogues – it is an additional treatment alongside (although I have heard of patients in the US being subscribed who are not receiving somatostatin analogue treatment)

Where is it currently approved?

The US FDA approved the drug 28 February 2017.

On 19 September 2017,the European Commission approved Xermelo® (telotristat ethyl) for the treatment of carcinoid syndrome diarrhea in patients inadequately controlled by somatostatin analogue therapy after the scientific committee of the EMA (known as Committee for Medicinal Products for Human Use (CHMP)) adopted a positive opinion recommending the approval of Xermelo® (telotristat ethyl) 250 mg three times a day for the treatment of carcinoid syndrome diarrhea in combination with somatostatin analogue (SSA) therapy in adults inadequately controlled by SSA therapy. The Ipsen press release is here.  Clearly some action will be required in EC national countries before the drug becomes available through the appropriate healthcare systems.


On 17 Oct 2018, Health Canada announced approval for Canadian NET patients – click here.

For all other countries please note that Ipsen will pursue a worldwide regulatory plan for marketing authorisation submissions in the territories in which it operates. Once approved, Ipsen will be distributing the drug in all countries less USA and Japan where Lexicon retains the rights. Outside USA and Europe will be constrained by national approval timelines.

How does it work?

In the simplest of terms, the drug is an inhibitor of the enzyme tryptophan hydroxylase (TPH).  TPH is the rate-limiting enzyme in serotonin synthesis which converts tryptophan (an essential amino acid which comes from diet) to 5-hydroxytryptophan, which is subsequently converted to serotonin, one of the main causes of carcinoid syndrome effects including carcinoid heart disease.  The trial data indicates that Telotristat ethyl significantly reduced the frequency of bowel movements. Furthermore, it was also associated with “significantly reduced levels of urinary 5-HIAA“, a marker for systemic serotonin levels, which are typically elevated in severe carcinoid syndrome.  Essentially it works by reducing the manufacture of Serotonin so it’s it may not have any effect on diarrhea not caused by syndrome (i.e. post surgery etc).

Neuroendocrine Cancer – Hormones

 

hormones

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 appreciate how important they are ……..like a lot of other things in life I suppose! The presence of over-secreting hormones (often called peptides throughout) is useful to aid diagnosis albeit it often means the tumours have metastasized. It’s also a frequent indication that the person has an associated NET syndrome.

This is a really complex area and to understand the hormone problems associated with Neuroendocrine Cancer, you need to have a basic knowledge of the endocrine and neuroendocrine systems.  I’ve no intention of explaining that (!) – other than the following high level summary:

  • Glands in the endocrine system use the bloodstream to monitor the body’s internal environment and to communicate with each other through substances called hormones, which are released into the bloodstream.  Endocrine glands include; Pituitary, Hypothalmus, Thymus, Pineal, Testes, Ovaries Thyroid, Adrenal, Parathyroid, Pancreas.
  • A Hormone is a chemical that is made by specialist cells, usually within an endocrine gland, and it is released into the bloodstream to send a message to another part of the body. It is often referred to as a ‘chemical messenger’. In the human body, hormones are used for two types of communication. The first is for communication between two endocrine glands, where one gland releases a hormone which stimulates another target gland to change the levels of hormones that it is releasing. The second is between an endocrine gland and a target organ, for example when the pancreas releases insulin which causes muscle and fat cells to take up glucose from the bloodstream. Hormones affect many physiological activities including growth, metabolism, appetite, puberty and fertility.
  • The Endocrine system. The complex interplay between the glands, hormones and other target organs is referred to as the endocrine system.
  • The Neuroendocrine System. The diffuse neuroendocrine system is made up of neuroendocrine cells scattered throughout the body.  These cells receive neuronal input and, as a consequence of this input, release hormones to the blood. In this way they bring about an integration between the nervous system and the endocrine system (i.e. Neuroendocrine).  A complex area but one example of what this means is the adrenal gland releasing adrenaline to the blood when the body prepares for the ‘fight or flight’ response in times of stress, ie, for vigorous and/or sudden action.

Hormones – The NET Effect

Hormones – the NET Effect

At least one or more hormones will be involved at various sites and even within certain syndromes, the dominant and offending hormone may differ between anatomical tumour sites. For example, NETs of the small intestine may overproduce serotonin and other hormones which can cause a characteristic collection of symptoms currently called carcinoid syndrome.   The key symptoms are flushing, diarrhea and general abdominal pain, loss of appetite, fast heart rate and shortness of breath and wheezing. The main symptom for me was facial flushing and this was instrumental in my eventual diagnosis. The fact that I was syndromic at the point of diagnosis made it easier to discover, albeit the trigger for the investigation was a fairly innocuous event.  Other types of NETs are also affected by the overproduction of hormones including Insulinomas, Gastrinomas, Glucagonomas, VIPomas, Somatostatinomas, and others.  These can cause their own syndromes and are not part of carcinoid syndrome as some organisations incorrectly state. For more on NET syndromes – Read Here.

So are hormones horrible? 

Absolutely not, they are essential to the normal function of the human body.  For example if you didn’t have any of the hormone Serotonin in your system, you would become extremely ill.  On the other hand, if your glands start secreting too much of certain hormones, your body could become dysfunctional and in some scenarios, this situation could become life threatening.  So hormones are good as long as the balance is correct. NET patients with an oversecreting tumor may be classed as “functional”.

  • Functional tumors make extra amounts of hormones, such as gastrin, insulin, and glucagon, that cause signs and symptoms.
  • Nonfunctional tumors do not make extra amounts of hormones. Signs and symptoms are caused by the tumor as it spreads and grows. Many NET patients are deemed to be “non-functioning” with normal hormone levels. It’s also accurate to say that many can move from one stage to the other.

Location Location Location

It’s accurate to say that the type and amount of hormone secretion differs between locations or sites of the functional tumor and this can also create different effects.  The division of NETs into larger anatomical regions appears to differ depending on where you look but they all look something likes this:

  • Foregut NETs: In the respiratory tract, thymus, stomach, duodenum, and pancreas. This group mostly lack the enzyme aromatic amino decarboxylase that converts 5-HTP (5-Hydroxytryptophan – a precursor to serotonin) to serotonin (5-HT); such tumours tend to produce 5-HTP and histamine instead of serotonin.
    • The Pancreas is a particularly prominent endocrine organ and can produce a number of different syndromes each with their associated hormone oversecretion – although many can be non-functional (at least to begin with), (see below for more detail). It’s also possible to see predominantly serotonin secreting tumors in places such as the pancreas (although what you would call that type of NET is open for debate).
    • Lung NETs rarely produce serotonin, but may instead secrete histamine causing an ‘atypical’ carcinoid syndrome with generalized flushing, diarrhea, periorbital oedema, lacrimation and asthma. They may also produce adrenocorticotropic hormone (ATCH) or corticotropin-releasing factor (CRP), resulting in an ectopic Cushing’s syndrome. Please note the respiratory tract and thymus are not really anatomically pure ‘Foregut’ – but in NETs, grouped there for convenience. 
    • Gastric (Stomach) NETs. Gastrin is the main hormone but there can also be histamine producing an atypical carcinoid syndrome effect.
  • Midgut NETs: In the small intestine, appendix, and ascending colon. For example, serotonin secreting tumors tend to be associated with carcinoid syndrome which tends to be associated with midgut NETs and this is normally the case. Many texts will also tell you that a syndrome only occurs at a metastatic stage.  Both are a good rule of thumb but both are technically incorrect. For example, ovarian NETs can have a form of carcinoid syndrome without liver metastasis (tends to be described as atypical carcinoid syndrome).
  • Hindgut NETs (transverse, descending colon and rectum) cannot convert tryptophan to serotonin and other metabolites and therefore rarely cause carcinoid syndrome even if they metastasise to the liver.
  • Less Common Locations – there are quite a few less common NET locations which may involve less common hormones – some are covered below including the key glands contributing to NETs.
  • Unknown Primary? –  One clue to finding the primary might be by isolating an offending hormone causing symptoms.

The key NET hormones

Serotonin

I used the example of Serotonin above because it is the most cited problem with NET Cancer although it does tend to be most prevalent in midgut tumors. Serotonin is a monoamine neurotransmitter synthesized from Tryptophan, one of the eight essential amino acids (defined as those that cannot be made in the body and therefore must be obtained from food or supplements). About 90% of serotonin produced in the body is found in the enterochromaffin cells of the gastrointestinal (GI) tract where it is used mainly to regulate intestinal movements amongst other functions. The remainder is synthesized in the central nervous system where it mainly regulates mood, appetite, and sleep. Please note there is no transfer of serotonin across the blood-brain barrier.

Alterations in tryptophan metabolism may account for many symptoms that accompany carcinoid syndrome. Serotonin in particular is the most likely cause of many features of carcinoid syndrome as it stimulates intestinal motility and secretion and inhibits intestinal absorption. Serotonin may also stimulate fibroblast growth and fibrogenesis and may thus account for peritoneal and valvular fibrosis encountered in such tumours; serotonin, however, it is said not to be associated with flushing. The diversion of tryptophan to serotonin may lead to tryptophan deficiency as it becomes unavailable for nicotinic acid synthesis, and is associated with reduced protein synthesis and hypoalbuminaemia; this may lead to the development of pellagra (skin rash, glossitis, stomatitis, confusion/dementia).

Serotonin is also thought to be responsible for ‘right sided’ heart disease (Carcinoid Heart Disease). It is thought that high levels of serotonin in the blood stream damages the heart, leading to lesions which cause fibrosis, particularly of the heart valves. This generally affects the right side of the heart when liver metastases are present. The left side of the heart is usually not affected because the lungs can break down serotonin. Right sided heart failure symptoms include swelling (edema) in the extremities and enlargement of the heart.

Whilst serotonin can be measured directly in the blood, it’s said to be more accurate to measure 5HIAA (the output of serotonin) via blood or urine, the latter is said to be the most accurate.

Tachykinins

Tackykinins include Substance P, Neurokinin A, Neuropeptide K and others. They are active in the enterochromaffin cells of the GI tract but can also be found in lung, appendiceal and ovarian NETs, and also in Medullary Thyroid Carcinoma and Pheochromocytomas. They are thought to be involved in flushing and diarrhea in midgut NETs. The most common tachykinin is Substance P, which is a potent vasodilator (substances which open up blood vessels). Telangiectasias are collections of tiny blood vessels which can develop superficially on the faces of people who have had NETs for several years. They are most commonly found on the nose or upper lip and are purplish in color. They are thought to be due to chronic vasodilatation.

Histamine

Histamine is a hormone that is chemically similar to the hormones serotonin, epinephrine, and norepinephrine. After being made, the hormone is stored in a number of cells (e.g., mast cells, basophils, enterochromaffin cells). Normally, there is a low level of histamine circulating in the body. However (and as we all know!), the release of histamine can be triggered by an event such as an insect bite. Histamine causes the inconvenient redness, swelling and itching associated with the bite. For those with severe allergies, the sudden and more generalized release of histamine can be fatal (e.g., anaphylactic shock). Mast cell histamine has an important role in the reaction of the immune system to the presence of a compound to which the body has developed an allergy. When released from mast cells in a reaction to a material to which the immune system is allergic, the hormone causes blood vessels to increase in diameter (e.g., vasodilation) and to become more permeable to the passage of fluid across the vessel wall. These effects are apparent as a runny nose, sneezing, and watery eyes. Other symptoms can include itching, burning and swelling in the skin, headaches, plugged sinuses, stomach cramps, and diarrhea. Histamine can also be released into the lungs, where it causes the air passages to become constricted rather than dilated. This response occurs in an attempt to keep the offending allergenic particles from being inhaled. Unfortunately, this also makes breathing difficult. An example of such an effect of histamine occurs in asthma. Histamine has also been shown to function as a neurotransmitter (a chemical that facilitates the transmission of impulses from one neural cell to an adjacent neural cell).

In cases of an extreme allergic reaction, adrenaline is administered to eliminate histamine from the body. For minor allergic reactions, symptoms can sometimes be lessened by the use of antihistamines that block the binding of histamine to a receptor molecule.  Histamine is thought to be involved with certain types and locations of NET, including Lung and foregut NETs where they can cause pulmonary obstruction, atypical flush and hormone syndromes.

Histamine, another amine produced by certain NETs (particularly foregut), may be associated with an atypical flushing and pruritus; increased histamine production may account for the increased frequency of duodenal ulcers observed in these tumours.

Kallikrein

Kallikrein is a potent vasodilator and may account for the flushing and increased intestinal mobility.

Prostaglandins

Although prostaglandins are overproduced in midgut tumours, their role in the development of the symptoms of carcinoid syndrome is not well established but triggering peristalsis is mentioned in some texts.

Bradykinin

Bradykinin acts as a blood vessel dilator. Dilation of blood vessels can lead to a rapid heartbeat (tachycardia) and a drop in blood pressure (hypotension). Dilation of blood vessels may also be partly responsible for the flushing associated with carcinoid syndrome.

Gastrin

Gastrin is a hormone that is produced by ‘G’ cells in the lining of the stomach and upper small intestine. During a meal, gastrin stimulates the stomach to release gastric acid. This allows the stomach to break down proteins swallowed as food and absorb certain vitamins. It also acts as a disinfectant and kills most of the bacteria that enter the stomach with food, minimising the risk of infection within the gut. Gastrin also stimulates growth of the stomach lining and increases the muscle contractions of the gut to aid digestion. Excess gastrin could indicate a NET known as a Gastric NET (stomach) or a pNET known as Gastrinoma (see pancreatic hormones below).

Endocrine Organs

Thyroid Gland

Calcitonin is a hormone that is produced in humans by the parafollicular cells (commonly known as C-cells) of the thyroid gland. Calcitonin is involved in helping to regulate levels of calcium and phosphate in the blood, opposing the action of parathyroid hormone. This means that it acts to reduce calcium levels in the blood. This hormone tends to involve Medullary Thyroid Carcinoma and Hyperparathyroidism in connection to those with Multiple Endocrine Neoplasia. Worth also pointing out the existence of Calcitonin Gene-Related Peptide (CGRP) which is a member of the calcitonin family of peptides and a potent vasodilator.  Please note that hypothyroidism is often a side effect of NETs or treatment for NETs – please click here to read about the connection.

Pituitary Gland

HPA AXIS – It’s important to note something called the HPA axis when discussing pituitary hormones as there is a natural and important connection and rhythm between the Hypothalamus, Pituitary and the Adrenal glands. However, I’m only covering the pituitary and adrenal due to their strong connection with NETs.

Adrenocorticotropic hormone (ATCH) is made in the corticotroph cells of the anterior pituitary gland. It’s production is stimulated by receiving corticotrophin releasing hormone (CRH) from the Hypothalamus. ATCH is secreted in several intermittent pulses during the day into the bloodstream and transported around the body. Like cortisol (see below), levels of ATCH are generally high in the morning when we wake up and fall throughout the day. This is called a diurnal rhythm. Once ACTH reaches the adrenal glands, it binds on to receptors causing the adrenal glands to secrete more cortisol, resulting in higher levels of cortisol in the blood. It also increases production of the chemical compounds that trigger an increase in other hormones such as adrenaline and noradrenaline. If too much is released, The effects of too much ATCH are mainly due to the increase in cortisol levels which result. Higher than normal levels of ATCH may be due to:

Cushing’s disease – this is the most common cause of increased ATCH. It is caused by a tumor in the pituitary gland (PitNET), which produces excess amounts of ATCH. (Please note, Cushing’s disease is just one of the numerous causes of Cushing’s syndrome). It is likely that a Cortisol test will also be ordered if Cushing’s is suspected.

A tumour outside the pituitary gland, producing ATCH is known as an ectopic ATCH. With NETs, this is normally a pNET, Lung/Bronchial/Pulmonary NET or Pheochromocytoma.

Adrenal Glands

Adrenaline and Noradrenline

These are two separate but related hormones and neurotransmitters, known as the ‘Catecholamines’. They are produced in the medulla of the adrenal glands and in some neurons of the central nervous system. They are released into the bloodstream and serve as chemical mediators, and also convey the nerve impulses to various organs. Adrenaline has many different actions depending on the type of cells it is acting upon.  However, the overall effect of adrenaline is to prepare the body for the ‘fight or flight’ response in times of stress, i.e. for vigorous and/or sudden action. Key actions of adrenaline include increasing the heart rate, increasing blood pressure, expanding the air passages of the lungs, enlarging the pupil in the eye, redistributing blood to the muscles and altering the body’s metabolism, so as to maximise blood glucose levels (primarily for the brain). A closely related hormone, noradrenaline, is released mainly from the nerve endings of the sympathetic nervous system (as well as in relatively small amounts from the adrenal medulla). There is a continuous low-level of activity of the sympathetic nervous system resulting in release of noradrenaline into the circulation, but adrenaline release is only increased at times of acute stress.  These hormones are normally related to adrenal and extra adrenal NETs such as Pheochromocytoma and Paraganglioma.  Like serotonin secreting tumours, adrenal secreting tumours convert the offending hormone into something which comes out in urine. In fact, this is measured (amongst other tests) by 24 hour urine test very similar to 5HIAA (with its own diet and drug restrictions).  It’s known as 24-hour urinary catacholamines and metanephrines.  Worth noting that adrenaline is also known as Epinephrine (one of the 5 E’s of Carcinoid Syndrome).

Cortisol

This is a steroid hormone, one of the glucocorticoids, made in the cortex of the adrenal glands and then released into the blood, which transports it all round the body. Almost every cell contains receptors for cortisol and so cortisol can have lots of different actions depending on which sort of cells it is acting upon. These effects include controlling the body’s blood sugar levels and thus regulating metabolism acting as an anti-inflammatory, influencing memory formation, controlling salt and water balance, influencing blood pressure. Blood levels of cortisol vary dramatically, but generally are high in the morning when we wake up, and then fall throughout the day. This is called a diurnal rhythm. In people who work at night, this pattern is reversed, so the timing of cortisol release is clearly linked to daily activity patterns. In addition, in response to stress, extra cortisol is released to help the body to respond appropriately. Too much cortisol over a prolonged period of time can lead to Cushing’s syndrome.  Cortisol oversecretion can be associated with Adrenal Cortical Carcinoma (ACC) which can sometimes be grouped within the NET family.

Other hormones related to ACC include:

Androgens (e.g. Testosterone) – increased facial and body hair, particularly females. Deepened voice in females.

Estrogen – early signs of puberty in children, enlarged breast tissue in males.

Aldosterone – weight gain, high blood pressure.

Adrenal Insufficiency (Addison’s Disease) occurs when the adrenal glands do not produce enough of the hormone cortisol and in some cases, the hormone aldosterone. For this reason, the disease is sometimes called chronic adrenal insufficiency, or hypocortisolism.

Parathyroid

Parathyroid hormone (PTH) is secreted from four parathyroid glands, which are small glands in the neck, located behind the thyroid gland. Parathyroid hormone regulates calcium levels in the blood, largely by increasing the levels when they are too low.  A primary problem in the parathyroid glands, producing too much parathyroid hormone causes raised calcium levels in the blood (hypercalcaemia – primary hyperparathyroidism). You may also be offered an additional test called Parathyroid Hormone-Related Peptide (PTHrP). They would probably also measure Serum Calcium in combination with these type of tests. The parathyroid is one of the ‘3 p’ locations often connected to Multiple Endocrine Neoplasia – MEN 1

Pancreatic Hormones (Syndromes)

Pancreatic neuroendocrine tumors form in hormone-making cells of the pancreas. You may see these described as ‘Islet Cells’ or ‘Islets of Langerhans’ after the scientist who discovered them. Pancreatic NETs may also be functional or non-functional:

  • Functional tumors make extra amounts of hormones, such as gastrin, insulin, and glucagon, that cause signs and symptoms.
  • Nonfunctional tumors do not make extra amounts of hormones. Signs and symptoms are caused by the tumor as it spreads and grows.

There are different kinds of functional pancreatic NETs. Pancreatic NETs make different kinds of hormones such as gastrin, insulin, and glucagon. Functional pancreatic NETs include the following:

  • Gastrinoma: A tumor that forms in cells that make gastrin. Gastrin is a hormone that causes the stomach to release an acid that helps digest food. Both gastrin and stomach acid are increased by gastrinomas. When increased stomach acid, stomach ulcers, and diarrhea are caused by a tumor that makes gastrin, it is called Zollinger-Ellison syndrome. A gastrinoma usually forms in the head of the pancreas and sometimes forms in the small intestine. Most gastrinomas are malignant (cancer).
  • Insulinoma: A tumor that forms in cells that make insulin. Insulin is a hormone that controls the amount of glucose (sugar) in the blood. It moves glucose into the cells, where it can be used by the body for energy. Insulinomas are usually slow-growing tumors that rarely spread. An insulinoma forms in the head, body, or tail of the pancreas. Insulinomas are usually benign (not cancer).
  • Glucagonoma: A tumor that forms in cells that make glucagon. Glucagon is a hormone that increases the amount of glucose in the blood. It causes the liver to break down glycogen. Too much glucagon causes hyperglycemia (high blood sugar). A glucagonoma usually forms in the tail of the pancreas. Most glucagonomas are malignant (cancer).
  • Pancreatic Polypeptide (PPoma). A pancreatic polypeptide is a polypeptide hormone secreted by the pancreatic polypeptide (PP) cells of the islets of Langerhans in the endocrine portion of the pancreas. Its release is triggered in humans by protein-rich meals, fasting, exercise, and acute hypoglycemia and is inhibited by somatostatin and intravenous glucose. The exact biological role of pancreatic polypeptide remains uncertain. Excess PP could indicate a pNET known as PPoma.
  • Other types of tumors: There are other rare types of functional pancreatic NETs that make hormones, including hormones that control the balance of sugar, salt, and water in the body. These tumors include:
  • VIPomas, which make vasoactive intestinal peptide. VIPoma may also be called Verner-Morrison syndrome, pancreatic cholera syndrome, or the WDHA syndrome (Watery Diarrhea, Hypokalemia (low potassium)and Achlorhydria).
  • Somatostatinomas, which make somatostatin. Somatostatin is a hormone produced by many tissues in the body, principally in the nervous and digestive systems. It regulates a wide variety of physiological functions and inhibits the secretion of other hormones, the activity of the gastrointestinal tract and the rapid reproduction of normal and tumour cells. Somatostatin may also act as a neurotransmitter in the nervous system.

The pancreas is one of the ‘3 p’ locations often connected to Multiple Endocrine Neoplasia – MEN 1

Having certain syndromes can increase the risk of pancreatic NETs.

Anything that increases your risk of getting a disease is called a risk factor. Having a risk factor does not mean that you will get cancer; not having risk factors doesn’t mean that you will not get cancer. Talk with your doctor if you think you may be at risk. Multiple endocrine neoplasia type 1 (MEN1) syndrome is a risk factor for pancreatic NETs.

Signs and symptoms of pancreatic NETs

Signs or symptoms can be caused by the growth of the tumor and/or by hormones the tumor makes or by other conditions. Some tumors may not cause signs or symptoms. Check with your doctor if you have any of these problems.

Signs and symptoms of a non-functional pancreatic NET

A non-functional pancreatic NET may grow for a long time without causing signs or symptoms. It may grow large or spread to other parts of the body before it causes signs or symptoms, such as:

  • Diarrhea.
  • Indigestion.
  • A lump in the abdomen.
  • Pain in the abdomen or back.
  • Yellowing of the skin and whites of the eyes.

Signs and symptoms of a functional pancreatic NET

The signs and symptoms of a functional pancreatic NET depend on the type of hormone being made.

Too much gastrin may cause:

  • Stomach ulcers that keep coming back.
  • Pain in the abdomen, which may spread to the back. The pain may come and go and it may go away after taking an antacid.
  • The flow of stomach contents back into the esophagus (gastroesophageal reflux).
  • Diarrhea.

Too much insulin may cause:

  • Low blood sugar. This can cause blurred vision, headache, and feeling lightheaded, tired, weak, shaky, nervous, irritable, sweaty, confused, or hungry.
  • Fast heartbeat.

Too much glucagon may cause:

  • Skin rash on the face, stomach, or legs.
  • High blood sugar. This can cause headaches, frequent urination, dry skin and mouth, or feeling hungry, thirsty, tired, or weak.
  • Blood clots. Blood clots in the lung can cause shortness of breath, cough, or pain in the chest. Blood clots in the arm or leg can cause pain, swelling, warmth, or redness of the arm or leg.
  • Diarrhea.
  • Weight loss for no known reason.
  • Sore tongue or sores at the corners of the mouth.

Too much vasoactive intestinal peptide (VIP) may cause:

  • Very large amounts of watery diarrhea.
  • Dehydration. This can cause feeling thirsty, making less urine, dry skin and mouth, headaches, dizziness, or feeling tired.
  • Low potassium level in the blood. This can cause muscle weakness, aching, or cramps, numbness and tingling, frequent urination, fast heartbeat, and feeling confused or thirsty.
  • Cramps or pain in the abdomen.
  • Facial flushing.
  • Weight loss for no known reason.

Too much somatostatin may cause:

  • High blood sugar. This can cause headaches, frequent urination, dry skin and mouth, or feeling hungry, thirsty, tired, or weak.
  • Diarrhea.
  • Steatorrhea (very foul-smelling stool that floats).
  • Gallstones.
  • Yellowing of the skin and whites of the eyes.
  • Weight loss for no known reason.

Too much pancreatic polypeptide may cause:

  • belly pain.
  • an enlarged liver.

Testing hormones

Clearly the presenting symptoms will give doctors a clue to the oversecreting hormone (see list above). Excessive secretions or high levels of hormones and other substances can be measured in a number of ways. For example:

Well known tests for the most common types of NET include 5-Hydroxyindoleacetic Acid (5-HIAA) 24 hour urine test which is also measured by a blood draw. Note: -tumor markers can be measured simultaneously e.g. Chromogranin A (CgA) blood test and/or Pancreastatin as there can very often be a correlation between tumour mass and tumour secreting activity. CgA / Pancreastatin is a blood test which measures a protein found in many NET tumour cells. These marker tests are normally associated with tumour mass rather than tumour functionality.

By measuring the level of 5-HIAA in the urine or blood, healthcare providers can calculate the amount of serotonin in the body (5-HIAA is a by-product of serotonin).  5-HIAA test is the most common biochemical test for carcinoid syndrome or the degree of how ‘functional’ tumours are.  If you’ve understood the text above, you can now see why there are dietary and drug restrictions in place prior to the test.

Pancreatic Hormone testing. There are other tests for other hormones and there is a common test which measured the main hormones seen in NETs. It may be called different things in different countries, but in UK, it’s known as a ‘Fasting Gut Hormone Profile‘.

Scratching the surface here so for a comprehensive list of marker tests for NETs, have a read here.

Treatment for Over-secreting Hormones

Of course, reducing tumour bulk through surgery and other treatment modalities, should technically reduce over-secretion (I suspect that doesn’t work for all).  Other treatments may have the dual effect of reducing tumour burden and the effects of hormone oversecretions.

One of the key treatment breakthroughs for many NET cancer patients, is the use of ‘Somatostatin Analogues’ mainly branded as Octreotide (Sandostatin) or Lanreotide (Somatuline). People tend to associate these drugs with serotonin related secretions and tumours but they are in actual fact useful for many others including the pancreatic NETs listed above.  Patients will normally be prescribed these drugs if they are displaying these symptoms but some people may be more avid to the drug than others and this may influence future use and dosages. This is another complex area but I’ll try to describe the importance here in basic terms. Somatostatin is a naturally occurring protein in the human body. It is an inhibitor of various hormones secreted from the endocrine system (some of which were listed above) and it binds with high affinity to the five somatostatin receptors found on secretory endocrine cells. NETs have membranes covered with receptors for somatostatin. However, the naturally occurring Somatostatin has limited clinical use due to its short half-life (<3 min). Therefore, specific somatostatin analogues (synthetic versions) have been developed that bind to tumours and block hormone release. Thus why Octreotide and Lanreotide do a good job of slowing down hormone production, including many of the gut hormones controlling emptying of the stomach and bowel.  It also slows down the release of hormones made by the pancreas, including insulin and digestive enzymes – so there can be side effects including fat malabsorption.

The recent introduction of Telotristat Ethyl (XERMELO) is interesting as that inhibits a precursor to serotonin and reduces diarrhea in those patients where it is not adequately controlled by somatostatin analogues.

Other than the effects of curative or cytoreductive surgery, some NETs may have very specialist drugs for inhibiting the less common hormone types.  This is not an exhaustive list.

Worth also noting that oversecreting hormones can contribute to a phenomenon (currently) known as Carcinoid Crisis – read more here.  For catacholamine secreting tumors (Pheochromocytoma/Paraganglioma), this may be known as Intraoperative Hypertensive Crisis

Sorry about the long article – it’s complex and you should always consult your specialist about issues involving hormones, testing for hormones and treating any low or high scores.

Thanks for reading
