NETwork with Ronny © – Community Newsletter OCTOBER 2017

Hi NETworkers!

Welcome to Ronny Allan’s Community newsletter for October 2017.  A very strong end of the month due to massive support for my Halloween themed but very serious and hard-hitting post “Neuroendocrine Tumors – no treats, just tricks”. If you’ve not seen it or commented on it, check it out here on the Facebook site.  I suspect the number of shares will never be beaten (652 in 36 hours).  31 Oct 2017 is now the biggest number of views on any one day, breaking the previous record set in Jan 2017.  It also made October 2017 the highest monthly views ever.  I am so grateful to those who made that happen ♥

What’s in the NET News

The following news items may be of interest:

  The huge (but expected) news that Novartis Novartis (manufacturers of Octreotide) is purchasing Advanced Accelerator Applications (AAA) (manufacturers of Lutathera Lu-177 (as used in PRRT)). This is a significant acquisition and should benefit the NET community given the size of Novartis and the potential of PRRT worldwide. It will be interesting to see if this has an impact on the UK approval

  I wasn’t at NANETS but did check most of the output consolidated into this post – Read more here

Made it to 3 finals in the WEGO Health awards, I posted about this  here.

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.

 Neuroendocrine Cancer – Trick or Treat.  This ‘themed’ post generated a huge amount of sharing, breaking all previous records.  See more in the newsletter.
  A summary of NET stuff from NANETS 2017
 “You’re Cured” – Topical and controversial in NETs. My opinion.
Weight can be an issue in NETs.  It did actually trigger my diagnosis.
The shock effect never wears off.  My private messages are full of disturbing stories, not just about diagnostic issues but support and care received.  A new campaign.
Genetics and NETs.
My first article for Cure Magazine “It’s not all about me” 

 

Other Activity

October was a busier month in terms of blogging despite several personal challenges and external projects on the go.  Striking a balance remains difficult, I’m keen to support and advocate but as a patient, I also need my own time.  I still managed to break 2 records in October, mainly due to my Halloween themed post on 31st.  The biggest amount of view in any one day had stood since Jan 2017 and was totally smashed, as was the best month too.   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 October 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 doing this!

  • Article features.
    • Cure Magazine.  I’ve been accepted as a ‘Cure Today’ contributor which means my articles will get a wider distribution than they do now.  Cure Magazine has a readership of 1 million.  Click here to read more. In October, I was featured in Cure Magazine twice:
“Cancer isn’t all about me”
“Poker Face or Cancer Card”
  • Twitter. I took part in a WEGO Health patient leader chat on twitter where I was able to contribute to some general cancer questions (subject chronic illnesses).  It was attended by many patient advocates representing many different conditions. The taking part in these activities is time-consuming and mentally 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 Oct, I tweeted 218 times on my personal account which lead to almost 89,000 views.  I was mentioned 160 times by other tweeters and gained 49 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 374 subscribers – up 11% 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.   This is the biggest cancer support organisation in the UK and I’m intent on developing relationships with various departments in this fantastic organisation.  They have recently agreed to feature NETs on 10 Nov 17 and I’m writing an article in preparation.
that’s me in the centre

Speaking Engagements

  • I was delighted to speak to the South Wales NET patient group (sponsored by NET Patient Foundation).  Here’s some pictures of Chris and I with the group and the local NET Specialist. Dr Mo Khan is setting up a brand new NET Service in Wales – great news for this group.
Left to right: Nikie Jervis (Nurse from NET Patient Forum), Sally Jenkins NET Cardiff, me, Yolande Mears NET Swansea, Chris (my wife)
Dr Mohid Khan – NET Specialist Wales – great supporter of my blog and NET patients Quality of Life
  • On 16 November, subject to contract, I’ve been invited to speak for around an 45 minutes at an Ipsen sponsored NET Nurse event in Birmingham. Tough gig!  Post to follow if allowed by contractual arrangements.

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.  Writing an article for Macmillan on NET Cancer Day.

Social Media and Stats

Blog Milestone.  In October, I accelerated past 400,000 views! Thank you all so much Keep sharing!  On track for half a million by Easter 2018.

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.

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 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.

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.

Lutetium Lu 177 dotatate (Lutathera®) – PRRT

prrt update

Background

There’s a lot of questions doing the rounds on forums and messages about the approval of Lutathera (PRRT) in USA, Europe and other places.  This is not a place just for one particular country, I want a place to review what is happening globally given my following.  In many countries, however, I’m dependent on feedback from patients in those countries. Please note this is not intended to be a 100% complete breakdown on everything about PRRT or PRRT centres – it’s a summary.  It should be clear from below but please bear that in mind when reading.

Short PRRT Primer

What is PRRT?

For those who are still not sure what it’s all about.  This is a non-surgical treatment which is normally administered intravenously.  It’s based on the use of somatostatin receptors to attract a ‘radiopeptide’.  The radiopeptide is a combination of a somatostatin analogue and a radioactive material. As we already know, somatostatin analogues (i.e. Lanreotide/Octreotide) are a NET cell targeting drug, so when combined radioactivity, it binds with the NET cells and delivers a high dose of targeted radiation to the cancer while preserving healthy tissue.  In general, patients tend to receive up to 4 sessions spaced apart by at least 2 months. 

PRRT will not work on all NETs and not everyone will suited to this treatment. In general, for this treatment to be more successful, you must have somatostatin receptors in your tumors. Success rates are not 100% – it should not be considered a cure or ‘magic bullet’. However, the results are said to be pretty good.  The NETTER-1 trial data which has led to formal approval in Europe, USA and other areas, can be found here.

THERANOSTICS

Understanding the terminology is half the battle in understanding the latest developments. I’ve included Ga-68 PET scans within this section (or in more general terms Somatostatin Receptor PET (SSTR PET)) as the term ‘Theranostics‘ is becoming a commonly used theme.  Theranostics is a joining of the words diagnostics and therapy.

LUTATHERA is the radionuclide ‘mix’ for use in Peptide Radio Therapy Treatment (PRRT).  You may also see this drug called ‘Lutetium’ or ‘Lu-177 dotatate’, or just ‘Lu-177’ on its own. Yttrium 90 (Y-90) is a  radionuclide also used in PRRT. 

NETSPOT (USA) or SOMAKIT TOC (Europe) is not PRRT but it is the commercial names for the radiopeptide used in Gallium 68 (Ga-68) PET diagnostic scans.

Together they form a ‘theranostic pair’. Theranostics is apt as together (NETSPOT / SOMAKIT TOC and Lutathera), both target NETs expressing the same somatostatin receptor, with Lutathera intended to kill tumor cells by emitting a different kind of low-energy, short-range radiation than that of the diagnostic version.

Moreover, thanks to the theranostic approach that nuclear medicine allows, Novartis/AAA’s NETSPOT/SomaKit TOC products will be able to determine when Lutathera is the appropriate treatment.

Read more about Theranostics by clicking here.

Hasn’t the therapy has been in use for some time?

Of course, this therapy has been in use in Europe and some other places for some time but to be honest, they have been on a limited scale and never formally approved by national drug agencies.  Despite its extensive use, the EU approval in 2017 was actually the very first approval of PRRT anywhere in the world. For example, in UK, it was used for some time for those in need but was removed from routine availability through a ‘slush fund’ formally known as the Cancer Drugs Fund – to cut a long story short, the funding source was cut off, although there are still ways of obtaining the treatment pending formal acceptance by the NHS (certain criteria apply).

In the meantime, I constantly see stories of patients travelling to Switzerland, Germany, Netherlands, Sweden, Great Britain and others; mostly at their own cost.   However, it does indicate one thing, there is a huge unmet need in that many patients do not have access to the best treatments in their own country. I see this daily through many private messages.

What about Grade 3 (High Grade) Neoplasms?  

The main treatment for Grade 3 is chemotherapy, particularly poorly differentiated.  PRRT tends to work better with efficient somatostatin receptors (i.e. somatostatin receptor-positive tumors).  The European approval wording only covers Grades 1 and 2. The US FDA approval indicates “somatostatin receptor-positive tumors”.  It’s also worth noting that with Grade 3, are more likely to exist in Grade 3 well differentiated NETs, particularly in the lower Ki-67 readings. However, there’s an interesting study from Australia which might be useful to read – check out the abstract here (note the full version is not available free).

What about Pheochromoctyoma/Paraganglioma?

There’s actually still a trial for Pheochromocytoma/Paraganglioma (Pheo/Para).  It is known that Pheo/Para can have somatostatin receptor tumors so a useful trial. The aim of the trial is to assess the safety and tolerability.  You can read about the trial here.

Regional Updates

The aim of this section is to update on a regional basis in order to inform an international community of followers and readers.

This section of this article will cover each region, indicating where PRRT can be obtained (as far as I know). It is not designed to indicate whether this is through public or private facilities (this will depend to too many factors beyond the reach of this article). Please note this is not intended to be a 100% complete breakdown on everything single PRRT centre – it’s a summary.  It should be clear from below but please bear that in mind when reading.

UNITED KINGDOM

On 29 August 2018. National Institute for Health Care Excellence (NICE) England has formally published that Lutetium (177Lu) oxodotreotide, within its marketing authorisation, is an option for treating unresectable or metastatic, progressive, well-differentiated (grade 1 or grade 2), somatostatin receptor-positive gastroenteropancreatic neuroendocrine tumours (NETs) in adults.  CLICK HERE to read the approval.  Currently available in London and Liverpool but there is talk of Newcastle going live soon. I await the rollout of PRRT – watch this space for a table listing. 

On 9 July 2018. The Scottish Medicines Consortium (NICE equivalent) has approved lutetium 177Lu (Lutathera) for patients in NHS Scotland. Good news for Scotland once their hospitals have the capability to deliver. Scottish patients would then not need to travel to England for the NHS Scotland funded treatment. Read more here.

It is funded in Wales and Northern Ireland but is currently administered in England with inter NHS budget transfers.

USA

PRRT was approved in USA on 26 Jan 2018. The approval is for the treatment of somatostatin receptor positive gastroenteropancreatic neuroendocrine tumors (GEP-NETs), including foregut, midgut, and hindgut neuroendocrine tumors in adults. CLICK HERE.

The extended access program (trial) is no longer offered but these locations should be ahead of the game in terms of provision, notwithstanding insurance and provision of sufficient nuclear material.

In the meantime, known USA sites offering routine “live site” insurance based PRRT treatment are as follows – please note information has been gleaned from US patients due to no other consolidated source of this information being readily available. It’s possible some patients got mixed up between trial locations and live locations so let me know of any omissions or additions/corrections – thanks in advance.

Canada

PRRT is only available at a few cancer centres in Canada. It can only be used with special approval from Health Canada or by taking part in a clinical trial

Europe (EU affiliated countries)

The European Medicines Agency (EMA) “market authorisation” received a positive indication on 20th July followed by EC approval on 29 Sep 2017.   The positive indication reads “Lutathera is indicated for the treatment of unresectable or metastatic, progressive, well differentiated (G1 and G2), somatostatin receptor positive gastroenteropancreatic neuroendocrine tumours (GEP NETs) in adults”. Of Course, the decision to fund the drug will be with national approval organisations.  Whilst I’m sure there are many more, these well-known centres have been making PRRT available for some years (but please note there are others):

Netherlands – Rotterdam Treatment Centre – click here

Sweden – Department of Endocrine Oncology Uppsala University Hospital – click here

Switzerland – University Hospital Basel, Radiology & Nuclear Medicine Clinicclick here

Germany – Zentralklinik Bade Berkaclick here

Denmark – ‘Rigshospitalet’ since 2009. They have treated around 250 patients- and given 800 treatments.

I’d be interested to hear from countries in Europe with their full list of centres or a link to it.

Australia

Australia seems to be ahead of the game or that is what I sense when I read output from there.  There’s a good section on the Australian effort – click here.

New Zealand

These guys have had to fight to get some progress on the provision of PRRT.  Currently New Zealanders have to go to Melbourne Australia for treatment – almost 50 New Zealanders with NETs are currently raising tens of thousands of dollars to pay for treatment in Australia because the life-prolonging treatment isn’t available locally. But this could change in 2018.  Unicorn Foundation New Zealand announced that Pharmac, the New Zealand government agency that decides which pharmaceuticals, have said that PRRT will be funded for patients with medium priority for the treatment of unresectable or metastatic, well-differentiated NETs (irrespective of primary site) that express somatostatin receptors.

  • radiopeptides in conjunction with other chemotherapies (check out my article PRCRT);
  • repeated administrations of the radiotherapies;
  • other radionuclide-peptide combinations.
  • increasing the number of indications for this therapy, including other disease targets;

Theranostics for Neuroendocrine Cancer – A Find and Destroy Mission

Neuroendocrine Cancer – we’re coming to get you! Graphic courtesy of Advanced Accelerator Applications

Theranostics is a joining of the words therapeutics and diagnostics. You may also see it conveyed as ‘Theragnostics’ and these terms are interchangeable.  The basic aim of theranotistics is to find and then destroy the ‘bad guys‘.  With Neuroendocrine Cancer, finding the tumours (the bad guys) can often be a challenge – they can be small and/or difficult to find – they are sometimes expert at camouflage.  Moreover, once found, they can then be difficult to treat (destroy), as they can often prove resistant to conventional cancer drugs and many are inoperable due to sheer quantity, spread and positioning.  When they are found and identified, it’s also really helpful to know from the intelligence gathered, how successful the destroy (therapeutic) part of the mission might be.  That is the beauty of theranostic pairing, i.e. the use of the same agent in the diagnostics – the ability to find, estimate likely success criteria and then hopefully destroy – or at least reduce the capability of the tumours and extend life.

A great example of an approved Theranostic Pair in Neuroendocrine Cancer, is the combination of the Somatostatin Receptor based Ga68  PET scan using NETSPOT or SomaKit TOC™ (US/Europe respectively) and Peptide Receptor Radiotherapy (PRRT) using Lutathera which both target NETs expressing the same somatostatin receptor, with PRRT intended to kill tumor cells by emitting a different kind of low-energy, short-range radiation than that of the diagnostic version. As mentioned above, the Ga68 PET scan can give a reasonably indication of therapeutic success using PRRT based on measurements taken during the scan (too complex for this article).

THERANOSTICS – FIND

Octreoscan vs Ga68 PET

Ga68 PET 

Newer imaging agents targeting somatostatin receptors (SSTR) labelled with 68 Ga have been developed, namely, DOTATATE, DOTATOC and DOTANOC. They are collectively referred to as SSTR PET.

The full titles of the 3 types are:

68Ga-DOTA-Phe1-Tyr3-Octreotide (TOC),
68Ga-DOTA-NaI3-Octreotide (NOC),
68Ga-DOTA-Tyr3-Octreotate (TATE).

The main difference among these three tracers (DOTA-TOC, DOTA-NOC, and DOTA-TATE) is their variable affinity to SSTR subtypes. All of them can bind to SSTR2 and SSTR5, while only DOTA-NOC shows good affinity for SSTR3.

These agents have several benefits over In111-pentetreotide (Octreotide scan), including improved detection sensitivity, improved patient convenience due to the 2 hour length of the study (compared to 2 or 3 days with Octreoscan), decreased radiation dose, decreased biliary excretion due to earlier imaging after radiotracer administration, and the ability to quantify uptake. The quantification of the uptake can help decide whether a patient is suitable for PRRT. Eventually, all Octreotide scans should be replaced with SSTR PET.  To confirm the advantages of SSTR PET over Octreotide scans, a study comprising 1,561 patients reported a change in tumour management occurred in over a third of patients after SSTR PET/CT even when performed after an Octreotide scan. Worth pointing out that SSTR PET is replacing the ageing Octreotide scan and not conventional imaging (CI).  You can see the recommended scenarios for use of SSTR PET in this article published by the Journal of Nuclear Medicine

Ga68 PET scans have been in many locations for some time. Current excitement is focused on USA locations with Ga68 PET (NETSPOT) only recently approved (DOTATATE). Other countries/scan centres may use one of the other types of imaging agent.

Read much more about this scan in my detailed article on Ga68 PET here.

So SSTR PETs above have the ability to find and estimate likely success criteria for therapy.  We are now in a position to move on to ‘THERApy’ – e.g.  Peptide Receptor Radiotherapy or PRRT.

Neuroendocrine Cancer – Exciting Times Ahead!  

exciting-times-ahead_edited

In the last 12-24 months, there seems to have been announcement after announcement of new and/or upgraded/enhanced diagnostics and treatment types for Neuroendocrine Cancer.  Scans, radionuclide therapies, combination therapies, somatostatin analogues, biological therapies, etc.  Some of the announcements are just expansions of existing therapies having been approved in new (but significant) regions. Compared to some other cancers, even those which hit the headlines often, we appear to be doing not too badly.  However, the pressure needs to stay on, all patients need access to the best diagnostics and treatments for them; and at the requisite time.  There’s even more in the pipeline and I’m hoping to continue to bring you news of new stuff as I have been doing for the last year.

Some of these new diagnostics and treatments will benefit eligible patients who are in diagnosis/newly diagnosed and also those living with the disease. As we’re now in our awareness month, let’s recap:

Scans

Many NET Patients will undergo a nuclear scan to confirm CT results and/or to detect further neuroendocrine activity.  Basically, a nuclear substance is mixed with a somatostatin analogue, injected into the patient who is then scanned using a 360-degree gamma camera.  As gamma cameras are designed to show up radioactive activity; and as Neuroendocrine Tumour cells will bind to the somatostatin analogue, it follows that the pictures provided will show where Neuroendocrine tumours are located.  Many people will have had an ‘Octreotide’ Scan (or more formally – Somatostatin Receptor Scintigraphy) which is still the gold standard in many areas. The latest generation of nuclear scans is based on the platform of the Gallium (Ga) 68 PET Scan. The principles of how the scan works is essentially as described above except that the more efficient radioactive/peptide mix and better scan definition, means a much better picture providing more detail (see example below). It’s important to note that positive somatostatin receptors are necessary for both scans to be effective. Europe and a few other areas have been using the Ga-68 PET scans for some time (although they are still limited in availability by sparse deployment). The latest excitement surrounding this new scan is because they are currently being rolled out in USA.  Read about the US FDA approval here.  You may hear this scan being labelled as ‘NETSPOT’ in USA but this is technically the name for the preparation radiopharmaceutical kit for the scan which includes a single-dose injection of the organic peptide and the radionuclide material. Take a look at a comparison of both scans here:

octreo-vs-g68
Octreoscan output vs Gallium 68 PET output

This slide from a recent NET Research Foundation conference confirms the power of more detailed scanning.

Peptide Receptor Radionuclide Therapy (PRRT)

Similar to above, this treatment has been in use in Europe and other places for some time but is also to be formally deployed in USA if, as is expected, the US FDA approval is positive at the end of this year (Read here).  In the most basic terms, this is a treatment whereby a peptide is mixed with a radionuclide and is drip fed over a number of treatments (normally up to 4 spaced out over a year). The concept of delivery of the ‘payload’ to the tumours is actually very similar to the preparation for a radionuclide scan as described above, the key difference is the dosage and length of exposure whilst the tumours are attacked. Once again, receptors are important. The NETTER series of trials showed good results and this is an excellent addition to the portfolio for those patients who are eligible for this treatment. Fingers crossed for the US FDA announcement due by the end of this year.  Also fingers crossed that PRRT returns to the NHS England & Wales portfolio of available treatments next year.  The Carcinoid Cancer Foundation has an excellent summary of PRRT here.

PRRT and Chemo Combo

Whilst on this subject, I also want to highlight the innovative use of combo therapies in Australia where they are combining PRRT and Chemo (PRCRT).  I blogged about this here:

PRRT CAPTEM

Somatostatin Analogues and their Delivery Systems

Somatostatin analogues are a mainstay treatment for many NET Patients.  These drugs target NET cell receptors which has the effect of inhibiting release of certain hormones which are responsible for some of the ‘syndromic’ effects of the disease.  Again, receptors are important for the efficacy of this treatment.  You can read the ‘geeky’ stuff on how they work here.  These drugs mainly comprise Octreotide (provided by Novartis) and Lanreotide (provided by Ipsen). The latter has been around in Europe for 10 years and was introduced to North America earlier this year.  Octreotide has been around for much longer, almost 17 years.  When you consider these peptides have also been used to support nuclear scans that can detect the presence of tumours; and that studies have shown they also have an anti-tumour effect, they really are an important treatment for many NET Patients.  I’ve blogged about new somatostatin analogues in the pipeline and you can read this here.  This blog also contains information about new delivery systems including the use of oral capsules and nasal sprays (…….. very early days though).

Treatment for Carcinoid Syndrome

telotristat-etiprate-clinical-trial-serotonin-as-a-key-driver-of-carcinoid-syndrome

For maintenance and quality of life, the release of a Telotristat Ethyl for Carcinoid Syndrome is an exciting development as is the first new treatment for Carcinoid Syndrome in 17 years.  This is a drug which is taken orally and inhibits the secretion of serotonin which causes some of the symptoms of the syndrome including diarrhea.  It must be emphasised it’s only for treating diarrhea caused by syndrome and might not be effective for diarrhea caused by other factors including surgery.  Read about how it works and its target patient group in my blog here.

Oncolytic Virus

oncolytic

The announcement of a clinical trial for the Oncolytic Virus (an Immunotherapy treatment) specifically for Neuroendocrine Tumours is also very exciting and offers a lot of hope. Click the photo for the last progress update.  

Everolimus (Afinitor)

013490_PNETUS_iPad_pg2v2

Earlier this year, AFINITOR became the first treatment approved for progressive, non-functional NETs of lung origin, and one of very few options available for progressive, non-functional GI NET, representing a shift in the treatment paradigm for these cancers.  It’s been around for some time in trials (the RADIANT series) and is also used to treat breast and kidney cancer.  It’s manufactured by Novartis (of Octreotide fame).  It has some varying side effects but these appear to be tolerable for most and as with any cancer drug, they need to weighed against the benefits they bring.

In technical terms, AFINITOR is a type of drug known as an ‘mTOR’ inhibitor (it’s not a chemo as frequently stated on NET patient forums).  Taken in tablet form, it works by blocking the mTOR protein. In doing so, AFINITOR helps to slow blood vessels from feeding oxygen and nutrients to the tumour.

Check out Novartis Afinitor website for more detailed information.  There’s an excellent update about AFINITOR rom NET expert Dr James Yao here.  The US FDA approval can be found here.

Summary

………. and relax!   Wow, I’ve surprised myself by collating and revising the last 12-24 months.  Dr James Yao also agrees – check out his upbeat message in the attached 2 page summary.  You may also like another upbeat message from Dr Jonathan Strosberg by clicking here.

Neuroendocrine Cancer – who’d have thought it?  ….. a bit of a dark horse.

Somatostatin Analogues and delivery methods in the pipeline

As 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 systems.

This is my live blog post covering new developments in the area of new Somatostatin Analogues and new delivery systems. 

Abstract

As 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 systems.

Those who have read the Octreotide/ Lanreotide patient leaflets will know those SSAs are also used in the treatment of a condition known as Acromegaly. You can see why the drug is used for both as they control the release of excess secretions of various substances, a problem that has an effect on both conditions. In the case of Acromegaly, the condition is typically caused by pituitary tumours that oversecrete the growth hormone leading to elevated levels of IGF-1. Like NETs, Octreotide/Lanreotide is currently the mainstay non-surgical treatment for this condition. For those not aware of Acromegaly there is a nice infographic explaining it here.   

Delivery methods discussed in this post include: a smaller, faster and easier Octreotide injection, an Octreotide capsule, an Octreotide nasal spray.  Other somatostatin analogues includes Pasireotide which has already been approved for Cushing’s Syndrome and Acromegaly (core NET possibilities have been investigated) and a new kid in the pipeline called Veldreotide for Acromegaly but potential additional applications in Cushing’s syndrome and neuroendocrine tumors. Finally for those with an interest in Cushings, a drug currently in phase 3 trials called RECORLEV™ (Levoketoconazole) which is not actually a somatostatin analogue, rather it’s a cortisol synthesis inhibitor.

It’s important to understand that NETs and other conditions including Cushings and Acromegaly, very often share the same hormone inhibiting drugs, thus why any development for these type of drugs is of interest to all physicians and patients in the associated conditions.

It’s also useful to understand that many of these drugs/delivery mechanisms are driven by availability of funding and are subject to the vagaries of the market. One entry on the previous version of this article has been removed as the company manufacturing it went into administration (Solid Dose Injections).

Somatostatin Analogues – New Delivery Methods in the Pipeline

New delivery system for Octreotide LAR – “Q-Octreotide” (MDT201)

757z468_1-SG02126-(1)
MTD201 (Q-Octreotide)

Updated 14 Dec 2017. Midatech Pharma has reported good results from a pre-clinical study of Q-Octreotide, its treatment for the side effects of Neuroendocrine tumours. The company’s speciality is drug delivery systems and MTD201 (Q-Octreotide) is a sustained release version of Octreotide designed to treat the incapacitating symptoms of metastatic Neuroendocrine Tumours, such as severe diarrhea and flushing. Q-Octreotide compared favourably with the standard Octreotide product and current market leader Sandostatin for acromegaly and carcinoid syndrome.

Apparently, the delivery method (see picture) is smaller, faster, easier. This project is expected to commence a Pilot study to compare the pharmacokinetics of Q-Octreotide versus Sandostatin LAR in humans mid-2017, followed by potential regulatory filings in 2018/19 and possible market approvals in the United States and the European Union thereafter. More to follow when known but in the meantime, please see a useful Video about Q-Octreotide. Apologies for the use of the out of date term ‘carcinoid‘.

New Octreotide Delivery Method – Chiasma Capsule

mycappsa
Octreotide Capsules? Graphic from http://www.chiasmapharma.com/

Updated 14 Dec 2017. Acromegaly appears to be in the lead in terms of new delivery methods.  A pharma company called Chiasma is working on an oral version of Octreotide for this condition and they are currently at Phase 3 trials.   You can check out the technology here.

Clearly, we want drugs to be safe and the announcement is another reminder of why drugs take so long to be approved.  Chiasma’s investigational oral octreotide uses their proprietary TPE® (Transient Permeability Enhancer) technology to facilitate gastrointestinal absorption of the unmodified drug into the bloodstream safely (i.e. it keeps the drug safe until it reaches its destination).  Hopefully, the new trial can convince the FDA to finally approve.  The trial is currently only Acromegaly based and details are here.

This is potentially an exciting development given that both conditions use the same drugs (Octreotide and Lanreotide injections) so there is always the hope that NETs might be next in line if the capsule version is finally approved.  However, still very early days as the company does not anticipate the release of top line date from the Phase 3 trial until 2020.

Updated 14 May 2017.  Dauntless Pharmaceuticals, Inc., a privately held biopharmaceutical company focused on the development of specialty therapeutics, announced the outcome of a Phase 1 clinical study to assess the safety, tolerability, pharmacokinetics, and pharmacodynamics of DP1038, a novel formulation of octreotide acetate for intranasal administration, compared to subcutaneous Sandostatin® (octreotide acetate) injection in healthy volunteers.  DP1038 (octreotide acetate for intranasal administration) is being developed via the 505(b)(2) regulatory pathway for the treatment of acromegaly and neuroendocrine tumors.  DP1038 leverages patented technology for enhanced intranasal absorption developed by Aegis Therapeutics, LLC, a drug delivery and drug formulation company that has successfully licensed its technology to leading pharmaceutical and biopharmaceutical companies whose partners have multiple late stage clinical programs under development. The drug will most likely use an administration system patented by Aegis called Intravail® Aegis Therapeutics LLC announced last year that it has been awarded U.S. Patent No. 9,446,134 providing non-invasive metered nasal spray delivery of Octreotide (click here to view the announcement). The enabling Aegis Intravail formulation technology is broadly applicable to a wide range of small molecule and biotherapeutic drugs to increase non-invasive bioavailability by the oral, nasal, buccal, and sublingual routes and to speed attainment of therapeutic drug levels in cases where a non-invasive (i.e., non-injectable) form of the drug is unavailable or where speed of onset is important.  A description of Intravail delivery systems can be found by clicking here.

About the Phase 1 Trial
The Phase 1 trial was designed to assess the safety, tolerability, pharmacokinetics and pharmacodynamics of DP1038, a novel formulation of octreotide acetate for intranasal administration, compared to subcutaneous Sandostatin® (octreotide acetate) Injection in healthy volunteers. In Part 1 of the study, each of 12 subjects received three doses of DP1038 plus 100 micrograms of subcutaneous octreotide acetate in a randomized 4 x 4 Latin square design. DP1038 was well tolerated across all doses and demonstrated a consistent, dose-proportional pharmacokinetic profile with significant nasal bioavailability. In Part 2 of the study, a single dose of DP1038, which was selected to exhibit a similar pharmacokinetic profile to subcutaneous octreotide acetate, was evaluated in 20 subjects in a cross-over design to compare the pharmacodynamic effect to 100 micrograms of subcutaneous octreotide acetate. Subjects were given a GHRH-arginine challenge, a standard test to stimulate growth hormone release, followed by administration of DP1038 or subcutaneous octreotide acetate. DP1038 showed comparable growth hormone suppression to the subcutaneous reference product. The news announcing the output from the Phase 1 clinical trial can be found by clicking here. Clearly, this is very early days and the product would need to go through the normal drug approval and acceptance routes etc.  However, a Phase 1 trial using patients is very exciting.

New Somatostatin Analogues in the Pipeline

New Somatostatin AnaloguePasireotide

signiforlar-22

Updated 14 Dec 2017.  Not really new but I wanted to include it because it’s not very well-known. Pasireotide is also known as Signifor and SOM230.  This drug is already in the pipeline but only for Acromegaly and Cushing’s Syndrome.  I found it interesting that is able to function as a multireceptor-targeted SSA by binding with high affinity to 4 of the 5 somatostatin receptors (sstrs 1, 2, 3 and 5), with the highest affinity for sstr5, resulting in inhibition of adrenocorticotropic hormone (ACTH) secretion (Octreotide only binds to sstrs 2, 3 and 5). In fact, Signifor represents the first specific treatment for ACTH-secreting pituitary adenomas.  Moreover, it is the first approved medical treatment for Cushing’s disease.  If you’ve read my blog on NET Syndromes, you will see the connection – both involve pituitary tumours and this drug is designed to cater for scenarios where surgery has not solved the problem or is not an option. Interestingly Novartis describes it as a second generation SSA, inferring that Octreotide is first generation.  It comes in short and long acting (LAR) forms with a similar delivery system to Octreotide. It is a US FDA approved orphan drug and is also approved for use in the EU.  Novartis has also submitted additional regulatory applications for Signifor LAR worldwide.   You can read more by clicking here

However, there have been studies in its use for advanced NETs where Octreotide is not working or has not sufficiently controlled the effects of the syndrome.  You can read a full text article about the study results by clicking here (you will recognise some of the authors including Edward M Wolin, Christos Toumpanakis, John Ramage, Kjell Öberg).  My interpretation of the trial conclusion is that there does not appear to be any significant advantages of Pasireotide over Octreotide.  The attachment also confirmed studies are ongoing including a potential combination treatment of Pasireotide and Everolimus (Afinitor).  There does not appear to be a study comparing it to Lanreotide.

Jonathan R. Strosberg, MD, associate professor at H. Lee Moffitt Cancer Center, discussed pasireotide as a potential treatment for patients with neuroendocrine tumors (NETs). He said “Pasireotide is a somatostatin analog similar to octreotide (Sandostatin) and lanreotide (Somatuline). However, pasireotide targets 4 out of the 5 somatostatin receptor subtypes, which may provide it with an advantage over the other 3 agents. Thus far, there has not been enough evidence showing that pasireotide has a progression-free survival benefit over the other 2 therapies. It is also associated with hyperglycemia. Pasireotide may be an appropriate choice for patients in later lines of therapy. In the future, he envisions that patients could be selected for therapy based on their somatostatin receptor profile.”

New Somatostatin Analogue  – Veldoreotide (COR-005)

Updated 14 Dec 2017. There is another new drug in the pipeline currently known as Veldoreotide or COR-005 (although I can see the term ‘Somatoprim’ used on other searches). COR-005 is an investigational SSA in phase 2 development for treatment of patients with Acromegaly. Although the page on the manufacturer’s website does not mention NETs, an announcement of its progress has just been made at the Endocrine Society’s annual conference for 2016. The announcement states that the drug has “potential additional applications in Cushing’s syndrome and neuroendocrine tumors”.  COR-005 targets somatostatin receptors 2, 4 and 5. Read about the drug here.

COR-005 has received orphan drug designation (only for Acromegaly) in the US and EU. There is not enough data to understand how this might benefit NETs and what the differences would be.  Hopefully, an update will be available later which will result in an update to this post.

For those interested in Cushing’s Syndrome, (hypercortisolism or high levels of cortisol), the same manufacturer working on Veldoreotide is also working on a new drug in Phase 3 trials known as RECORLEV™ (Levoketoconazole). Not actually a somatostatin analogue, rather it’s a cortisol synthesis inhibitor

Summary

This information is provided for information only.  There is no intent to indicate at this point that these new drugs will eventually be approved for NETs.  However, it’s another indication that people are working on new treatments which might end up being available at some stage.

The pipeline for new treatments and methods of delivery continues to grow!

Neuroendocrine Neoplasms – Grade and Stage (incorporating WHO 2017 changes)

Grades of Neuroendocrine Tumour WHO 2017 15 Dec 2017

One of the most discussed and sometimes confusing subjects on forums is the staging and grading of Neuroendocrine Neoplasms (NENs). Mixing them up is a common error and so it’s important to understand the difference despite the apparent complexity. If I was to make a list of questions for my specialist/Oncologist at diagnosis, it would include “What is the stage, grade and differentiation of my cancer”.  To enable me to synchronise with the documented guidance, I’m going to use the following WHO 2017 approved terms in this post:

  • Neuroendocrine Neoplasm (NEN) – all types of Neuroendocrine tumour of whatever grade (please note Neoplasm is another word for tumour)
  • Neuroendocrine Tumour (NET) – all well-differentiated tumours (an explanation of differentiation will be provided below)
  • Neuroendocrine Carcinoma (NEC) – all poorly differentiated tumours

NEN Breakdown

Stage vs Grade

In the most basic of terms, stage is the spread or extent of cancer and grade is the aggressiveness of cancer. They are totally different things and an understanding of both is important as they are critical to predict outcome (to a certain extent) and guide therapy. There is no correlation between the two, you can have the lowest grade with the highest stage (actually very common with NETs).

As patients, we deal with many medical specialists during diagnosis and subsequent treatment.  However, we rarely meet the pathologist who plays a critical role in the outcome. Precise diagnosis is what drives patient decisions and treatment. If the pathology is wrong, everything that follows could be incorrect as well.  It’s a very important area.

Why is differentiation important?

To fully understand grading, you also need to understand the concept of ‘differentiation’.  In the most basic of terms, ‘differentiation’ refers to the extent to which the cancerous cells resemble their non-cancerous counterparts.  This is an important point for NETs because many low-grade tumour cells can look very similar to normal cells. The differentiation of a NET has an impact on both prognostics and treatment regimes.

NENs fall into one of three grades based on their differentiation and their proliferative rate. The proliferative rate is measured mainly using two methods known as Miotic Count and Ki-67 index, the latter seems to be more frequently used (but see below for Lung NETs). The Ki-67 index can usually be determined, even in cases of small biopsies but Mitotic rate counting requires a moderate amount of tumour tissue (at least 50 HPFs or 10 mm) and may not be feasible for small biopsies.  The Miotic Count method may be preferred or used in addition to Ki-67 for certain Lung NET scenarios as it is said to be more helpful in distinguishing atypical from typical NET (what some might ‘old fashionably’ and incorrectly refer to as Lung Carcinoid tumours), and for small and large cell lung Neuroendocrine Carcinomas (NEC).

Some of you may have heard the term ‘moderately differentiated’ which tended to align with an intermediate grade or Grade 2. However, please note that the term moderately differentiated as a classification was phased out in 2010 by WHO reducing from 3 differentiation levels to 2.  Grade 2 is also defined as well differentiated but based on different proliferative rate (see table). High grade was normally referred to as Neuroendocrine Carcinoma indicating it is a faster growing and more aggressive cancer. However, see below for an important change to high grade classification.

Grading – Key WHO 2017 Changes

WHO Classifications of Cancer are published in something known in medical world as “The Blue Book”.  For NETs, the 2017 version comprises only the “WHO Classification of Tumours of Endocrine Organs”.  Technically this would preclude the digestive system and lung NETs but I’m told on good authority from world leading pathologists and from listening to lectures at ENETS 2018, that the classification in the leading picture is to be used for all NENs. Worth also noting that the latest ENETS Guidelines are already using the new grading terms.  Many sites remain out of date so be careful where you look.

The 2017 World Health Organisation (WHO) classification sub-divided Grade 3 into two new entities: a well differentiated high-grade NET and a poorly differentiated high-grade NEC.  There may also be a cut-off point in proliferative rate (i.e. Ki-67) between NET and NEC in relation to potential treatment strategies (55% is mentioned for pNETs but I’m currently investigating).

The Grade 1 to 2 Ki-67 cut-off is changed from 2 to < 3 for clarification purposes.  There was some discussion as to whether it should be <5 but this was not accepted.

Well differentiated High Grade NETs are now recognised.  These are known as a NET rather than a NEC.  Both Grade 3 (NET) and Grade 3 (NEC) have the same biopsy marker cut-offs as per the leading slide but it is thought that a threshold reading of 55% could have some influence on the treatment regime. For example, a well differentiated tumour with a Ki67 of less than 55% might benefit from the same treatment given to Grade 1 or 2 patients, whereas a well differentiated tumour with a Ki67 of less than 55% might benefit from the same treatment given to poorly differentiated NEC. I suspect this is like many things in NENs, very individual, relies on many factors, so your specialist will drive this accordingly.  You may see these 2 grades listed as Grade 3a for NET and Grade 3b for NEC.

Previously, Pheochromocytoma did not have an official grading regime, i.e. they were just benign or malignant.  Now they are using the same grading system as above.  I’m assuming this is the same for Paraganglioma and I will confirm in due course.  This is an excellent change and a continuation from the WHO 2010 classification where there was great emphasis away from a benign/malignant classification to formal grade levels on the basis that all NETs have malignant potential.

It also introduced a change to the naming of mixed cell tumours from Mixed AdenoNeuroendocrine Carcinoma (MANEC) to Mixed Neuroendocrine Non-Neuroendocrine Neoplasms (MiNEN).  A full explanation of this MiNEN will follow but I would suggest the use of the term ‘Neoplasm’ has been chosen rather than ‘Carcinoma’ is because these neoplasms can be well or poorly differentiated.

It’s not possible at this time to acquire copies of the official output but I will keep this blog live.

The source material for the 2017 version of this article.

From leading Pathologist Dr Anthony Gill  – Remember this is based on Endocrine Organs only but it will eventually apply to all.   I am awaiting access to free documentation to update this article further – only ones I can currently find are not free!

Misc Grading Issues

The proliferative rate can be diverse in NENs, so sampling issues can limit the accuracy of grading. More substantial samples of tumour are therefore preferable for grading thus why the Ki-67 index is preferred for biopsies where large amounts of tissue may not be available. The distinction of low-grade from intermediate grade can be challenging when using small samples. A couple of interesting observations about NET grading which I spotted during my research and ‘forum watching’.  You can have multiple primary tumours and these might have different Ki-67 scores.  Additionally, on larger tumours, Ki-67 scores can be different on different parts of the tumour.  And something I know from my own experience, secondary tumours can have different Ki-67 scores than primary – even a different grade.  In my own case, my liver secondary tumours were graded higher than my primary which according to my surgeon is in keeping with a clone of the disease having become more aggressive over time.  Royal Free Hospital NET Centre indicates a person’s grade should be taken from the highest biopsy grade taken. This is a fairly complex area but a recent study published by the US National Institute of Health and many anecdotal comments made by NET specialists indicates that is a fairly common scenario.

Staging (spread)

Staging is the extent or spread of disease.  Most types of cancer have 4 stages, numbered from 1 to 4 indicating a rising spread as the number is bigger. Often doctors write the stage down in Roman numerals, perhaps this is to stop any confusion between standard numbers used for Grades? So you may see stages written as I, II, III and IV.  In addition to this standard method, there is also an agreed model known as TNM (Primary Tumour, Regional Node, Distant Metastasis) which is essentially a more detailed staging definition when combined with the Stage 1-4 model.  Please note with TNM models, there could be different stage descriptions depending on the location of the primary tumour and similarly different TNM models for different tumour locations.

WHO 2017 changes

WHO 2017 has recommended enhancements to the TNM system mainly the use of additional suffixes indicating the extent of lymph node involvement. Details to follow when I can free access.

The following example shows the stage descriptions for a NET of the small intestine (the others are similar but worded accordingly for that part of the anatomy):

Stage I tumour is less than 1 cm in size and has not spread to the lymph nodes or other parts of the body.

Stage II tumour is greater than 1 cm in size and has started to spread beyond the original location, but has not spread to the lymph nodes or other parts of the body.

Stage III is any size tumour that has spread to nearby areas of the body and also to at least one lymph node.

Stage IV is any size tumour that has spread to one or more lymph nodes and has also spread to other, more distant areas of the body (such as the liver).

It’s also worth pointing out that Stage IV does not necessarily mean a cancer is more dangerous than other cancers of lesser stages.  This is an important point for NETs where Stage 4 can be matched up with a low-grade tumour i.e. Stage 4 for lower grade NETs is very often not the ‘red flag’ it is for other more aggressive cancers.  For example, doctors may surgically remove a Stage IV NET, while surgery might not help a patient with a cancer of a higher grade at such a late stage.

Notes:

  • Sometimes doctors use the letters to further divide the number categories – for example, stage 2A or stage 3B.  This is normally to clarify or provide more detail of the primary tumour size/invasion in conjunction with the TNM model.
  • You may also see something called Stage 0 which is for ‘Carcinoma in situ’. It means that there is a group of abnormal cells in an area of the body. However, the number of abnormal cells is too small to form a tumour and may, therefore, be currently classed as benign.  The World Health Organisation (WHO) system does not appear to recognise Stage 0 for NETs.

The most generic model for TNM staging is below but please note this could be adjusted for particular types of NET.

Primary Tumor (T)
TX: Primary tumor cannot be evaluated
T0: No evidence of primary tumour
Tis: in situ (abnormal cells are present but have not spread to neighbouring tissue; although not cancer, in situ may become cancer and is sometimes called preinvasive cancer)

T1, T2, T3 and T4 is a measure of the size of, and/or invasion/penetration by, the primary tumour and the wording varies between different NET sites. e.g. for a small intestinal NET:

T1 tumour invades mucosa or submucosa and size <=1 cm

T2 tumour invades muscularis propria or size >1 cm

T3 tumour invades subserosa

T4 tumour invades the visceral peritoneum (serosa)/other organs

For any T add (m) for multiple tumours

Regional Lymph Nodes (N)
NX: Regional lymph nodes cannot be evaluated
N0: No regional lymph node involvement
N1: regional lymph node metastasis

Distant Metastasis (M)
MX: Distant metastasis cannot be evaluated
M0: No distant metastasis
M1: Distant metastasis is present

You may occasionally see TNM staging be prefixed by lower case letters.  The most commonly used prefix is ‘p’ simply meaning the grading has been confirmed by pathology.  e.g. pT4 N1 M1

Specialists can combine the Stage to create a TNM – for example:

This slide will be updated when I get access to WHO 2017 or updated AJCC pubication.

Summary

A complex area and I hope I have condensed it sufficiently for you to understand enough for your purposes.  Despite looking very scientific, it is not an exact science. There are many variables as there always are with Neuroendocrine disease.  NENs can be very challenging for a pathologist even an experienced one who may not have encountered NENs before.  However, it is an extremely important part of initial diagnosis and also when needed during surveillance.  It is a vital tool used by Multidisciplinary Teams (MDT) in treatment plans and for prognostic purposes.  If you need to learn further, I recommend this document:

If you are interested in this subject and have one hour to spare, there is a great video here from LACNETS worth watching.

Finally – always make sure you get your pathology results at diagnosis and following any subsequent sampling.
