Phase 1 clinical trial of single agent PV-10 for the treatment of symptomatic neuroendocrine tumors (NET) metastatic to the liver

An interesting trial from Provectus Biopharmaceuticals Inc.  Phase 1 results were presented at the American Society of Clinical Oncology (ASCO) 2019 Annual Meeting, held in Chicago, IL from May 31-June 4, 2019

In an ogoing Phase 1 clinical trial of single agent PV-10 for the treatment of symptomatic neuroendocrine tumors (NET) metastatic to the liver. Intralesional injection of oncolytic immunotherapy PV-10 can yield immunogenic cell death in solid tumor cancers that results in tumor-specific reactivity in circulating T cells. PV-10 clinical development includes cutaneous melanoma, hepatocellular carcinoma, and metastatic liver cancers such as uveal melanoma in single-agent and combination therapy settings.

What is PV-10?

Described above as “Oncolytic Immunotherapy” but elsewhere as “Ablative Immunotherapy”, the latter indicates the method of administering the therapy i.e. tumour ablation.  It’s more well known for trials in treating Melanoma where tumour ablation (albeit subcutaneous) is more common as a treatment.

Scientific Description: PV-10 causes acute oncolytic destruction of injected tumors, releasing damage associated molecular pattern molecules (DAMPs) and tumor antigens that initiate an immunologic cascade where local response by the innate immune system facilitates systemic anti-tumor immunity by the adaptive immune system. The DAMP release-mediated adaptive immune response activates lymphocytes, including CD8+ T cells, CD4+ T cells, and NKT cells, based on clinical and preclinical experience in multiple tumor types. T cell function can be further augmented by combining PV-10 with immune checkpoint inhibition.  Sometimes it’s known as its short name “Rose Bengal“.

What is ‘Rose Bengal’?

It’s actually a 135 year old chemical stain, originally discovered in 1882, and for more than half a century used as a dye in cancer diagnosis.

Rose Bengal, in a 10% solution known as PV-10, has displayed greatest promise in the treatment of melanoma, where it was shown in an 80-patient Phase II trial to achieve a complete response rate in 50% of patients’ tumours and an overall response in 71%. A bystander effect was also seen in untreated lesions, suggesting a positive immune response, although it was more effective when all lesions were injected with PV-10.

Scientific Description: PV-10’s active pharmaceutical ingredient is rose bengal disodium (RB) (4,5,6,7-tetrachloro-2’,4’,5’,7’-tetraiodofluorescein disodium salt), a small molecule halogenated xanthene. PV-10 drug product is a bright rose red solution containing 10% w/v RB in 0.9% saline for injection, which is supplied in single-use glass vials containing 5 mL (to deliver) of solution and administered without dilution to solid tumors via intratumoral injection.

What is the trial doing and where is the trial located?

This single-center Phase 1 study is being conducted at The Queen Elizabeth Hospital in Adelaide, Australia to evaluate the potential safety, tolerability, and preliminary efficacy of PV-10 in metastatic NET patients (NCT02693067). The primary endpoint for the trial is safety, and secondary endpoints include objective response rate (ORR) of injected target and measurable bystander lesions, target lesion somatostatin receptor expression, and biochemical response. Six patients in the first cohort each received one percutaneously-administered injection of PV-10 to one target lesion per treatment cycle. Patients in the second cohort can receive PV-10 injection of multiple lesions per cycle (2 of 6 patients in the second cohort have received at least one cycle of PV-10 thus far).

Results of Cohort 1 as follows:

Cohort 1 has fully enrolled, with 4 of 6 subjects male, median age 65yrs, range 47-72. Primary sites were: small bowel 3, pancreas 2, caecal 1; grade: Gd1 = 5, Gd2 = 1. All patients received prior Somatostatin Analogues (SSA) and PRRT. Median CgA was 645 (range 30-2819). To date 1 subject has received 4 PV-10 treatment cycles, 1 has received 2 cycles, and 4 have received a single cycle. Toxicity has been acceptable, including pain post procedure, carcinoid flare and nausea. LFT’s have remained stable. Overall QOL score was stable for 5 of 6 subjects. ORR in injected lesions is 50% (progression in 1 subject), with overall disease control of 84%. CgA response: 5 stable, 1 progression. One subject with “carcinoid pellagra” had rash resolution. Response follow-up is ongoing and additional efficacy and functional data will be presented. Hepatic IL PV-10 elicited no safety concerns with encouraging evidence of both local and systemic disease control. Enrolment to Cohort 2 is underway

LUTATHERA (PRRT) – NETTER 2 Clinical Trial for Grade 2/Grade 3 Neuroendocrine Neoplasms

netter 2

Brief Summary:

The NETTER-1 trials led to the approval of Lu177 (or Lutathera), more commonly known in the community as Peptide Receptor Radio Therapy (PRRT).  This led to an explosion of availability across the world but many gaps in service remain.

Many PRRT spin off trials are in the pipeline looking at different types of PRRT, mainly using slightly different radionuclides and techniques.  However, NETTER-2 builds on the success of the approved version formally known as Lutathera.

The aim of NETTER-2 is to determine if Lutathera in combination with long-acting octreotide prolongs PFS in GEP-NET patients with high proliferation rate tumors (G2 and G3), when given as a first line treatment compared to treatment with high dose (60 mg) long-acting octreotide. Somatostatin analog (SSA) naive patients are eligible, as well as patients previously treated with SSAs in the absence of progression.

This is a phase 3 trial that will be hoping for 222 participants at multiple locations.

This article will be fleshed out in due course. No locations listed yet.  Not recruiting yet.  Criteria listed – important section if this trial interests you. Clinical Trials document here.

In the meantime, read more about Lutathera (PRRT) by clicking here.

This looks like a very exciting development.

Crinetics Pharmaceuticals Initiates Phase 1 Study of CRN01941 for the Treatment of Neuroendocrine Tumors


Crinetics Pharmaceuticals, Inc. (Nasdaq: CRNX), a clinical stage pharmaceutical company focused on the discovery, development, and commercialization of novel therapeutics for endocrine diseases and endocrine-related tumors, today announced the initiation of a Phase 1, double-blind, randomized, placebo-controlled, single and multiple-dose study to evaluate the safety, pharmacokinetics, and pharmacodynamics of CRN01941 in healthy volunteers.

What is CRN01941?

It’s an oral nonpeptide somatostatin receptor subtype 2 (sst2) biased agonist* designed for the treatment of neuroendocrine tumors (NETs) that originate from neuroendocrine cells commonly found in the gut, lung, or pancreas.  From the detail contained in the clinical trials document (see below), it appears to involve a capsule.  I’m guessing that the use of terms such as ‘non-peptide’ means that it may not be the same as a somatostatin analogue, but the method of operation appear to be similar in that it wants to bind to somatostatin receptor 2 (SST2).   I will bring more technical detail once I have it.  * chemical that binds to a receptor and activates the receptor to produce a biological response.

This trial launch follows other products including a similar capsule based somatostatin receptor product for treating Acromegaly called CRN00808,  currently undergoing two Phase 2 clinical trials. The company is also developing oral nonpeptide somatostatin agonists for hyperinsulinism, as well as oral nonpeptide ACTH antagonists for the treatment of Cushing’s disease.

On the basis that the CRN00808 Phase 2 trial for Acromegaly is using patients previously treated with somatostatin analog based treatment regimens, I suspect this drug is designed for the same market as Sandostatin LAR/Octreotide and Somatuline (Lanreotide).  For more information, please visit www.crinetics.com.

The Phase 1 Clinical Trial of CRN01941 for NETs

The trial is initially only based in Perth Western Australia, it is not yet known if there are any plans to expand locations in subsequent phases or parts of the trial.  It also appears they are trialling the use of a capsule based drug and another delivery method as yet unknown, the clinical trial only mentions “Oral Solution” so it isn’t an injection.   Read more at ClinicalTrials.gov using the identifier NCT03936166.

This is not the first somatostatin receptor based product in the pipeline, please also check out my article about Somatostatin Analogues and Delivery Mechanisms in the pipeline – click here.

Neuroendocrine Neoplasms – High grade



High Grade – the forgotten patient group?

When reading articles in the mainstream media, found in medical publications; and even listening to doctors speak about my disease, it’s clear that the focus is on the term “Neuroendocrine Tumours” or NET for short.  Many websites of advocate foundation organisations and specialist scientific organisations, all still use the term “NET” in their naming.  I too am guilty of having a large Facebook site falling into this category.  It’s little wonder that those with high grade disease can often feel like the forgotten patient group.  Clearly all the aforementioned organisations support all patients regardless of grade, but it’s true to say that the naming and general use of terminology continues to fall behind. It’s also true that the term NET remains applicable to the majority of patients and that many use it as a convenience when they actually mean all types including Neuroendocrine Carcinoma. Nonetheless, context remains an important part of overall understanding and inclusivity – words and acronyms matter.

However, High grade or Grade 3 is no longer just Neuroendocrine Carcinoma (NEC).  Things have changed since 2017.

What are Neuroendocrine Neoplasms?

Neuroendocrine neoplasms (NENs) are without doubt a heterogeneous (i.e. diverse) bunch of tumours with a common phenotype (i.e. the physical appearance or biochemical characteristic).  However, there are two fundamentally different groups of NENs: well-differentiated, low-proliferating NENs, called neuroendocrine tumours (NETs), and poorly differentiated, highly proliferating NENs, called neuroendocrine carcinomas (NECs).  The difference between well and poorly differentiated has been described as a ‘dichotomy’, most likely due to the origin from different neuroendocrine progenitor cells (i.e. source cells). Should the term Neuroendocrine Neoplasm be used more?  Yes, probably. But should we perhaps also ask if ENETS and NANETS will change their names to ENENS and NANENS?

This revised classification is not recent as many are currently suggesting.  These changes were covered in my Staging and Grading article produced in early 2017 and confirmed Neuroendocrine Neoplasms (or NENs) was the overarching term for all types of neuroendocrine disease.  See graphic below.

Traditionally, any proliferation score over 20% on the Ki-67 proliferation index (or over 20 mitoses/10 HPF on the Mitotic Index) would have been deemed a Neuroendocrine Carcinoma.  However, in the pancreas, NETs and NECs may overlap in their proliferation index, making the distinction between them difficult and leading to treatment uncertainties.

In 2017, the Endocrine ‘Blue Book’ of cancer classification systems introduced a new pancreatic NET category based on a Grade 3 tumour which is well differentiated (i.e. cancer cells look more like normal cells and tend to grow and spread more slowly).  While all classifications for all NENs recognise the existence of the two major groups (NET and NEC), there are proposals to develop common NEN classification across all the ‘Blue Books’ and future versions will reflect these changes. The most interesting change will be in the Lung classification because high grade NENs can be small cell or large cell and it’s probably the most controversial grouping.

Interestingly, ENETS guidelines already use the term across the board in their 2016 series (i.e. in advance of the 2017 changes).  These changes are part influenced by the results of the NORDIC NEC study which showed that although patients with a Ki67 <55% were less responsive to platinum-based chemotherapy (i.e. drug names ending in ‘platin’ such as Cisplatin, Carboplatin, Oxaliplatin), they had a longer survival, and concluded that not all NEC should be considered as one single disease entity.  Also worth noting that the NORDIC NEC study covered many different areas of the anatomy, not just the pancreas. Some of the rationale for the division of grade 3 into well differentiated NETs and poorly differentiated carcinomas is that some grade 3 tumours which are classified into this category according to the Ki67 index percentage, have been recognised to behave more like grade 2 NETs rather than aggressive carcinomas. The inference is that there could be treatment and prognostic significance if a patient is a Grade 3 NET.

MANEC vs MiNEN

Added for completeness.  This mixed and rare neoplasm type has traditionally been related to NEC but in 2017 the nomenclature change to a new term was necessary to reflect the fact that some of the tumours involved were not carcinomas or adenocarcinomas but rather were well differentiated tumours or even adenomas (i.e. benign). Previously known as Mixed AdenoNeuroendocrine Carcinoma (MANEC), they were renamed to Mixed Neuroendocrine Non-Neuroendocrine Neoplasms (MiNEN).

MiNEN are neoplasms with two distinct neuroendocrine and non-neuroendocrine cell populations. They can be morphologically classified into three entities: collision, composite, and amphicrine MiNEN. Currently, both components composing a MiNEN must represent at least 30% of the whole tumour.  Diagnosis of MiNEN is usually facilitated by the presence of at least one well-differentiated component which may be the Neuroendocrine or Non-Neuroendocrine component. However, the two components may be difficult to identify with conventional morphological techniques, particularly when they are poorly differentiated, and their identification may require additional immunohistochemical techniques. MiNEN usually originate from organs that contain neuroendocrine cells and in which “classical” NENs are known to develop, such as pancreas, appendix, colon, and to a lesser degree small intestine. Other locations in my source document includes Oesophagus, Stomach, Bilary Tract and Gallbladder, Duodenum and Ampulla of Vater and Rectum.

NEC vs NET

Having researched widely, I believe there are 8 key differences between NET and NEC:

      1. Grade – NEC is only Grade 3, NETs can be Grade 1, 2 or 3.
      2. Differentiation – all NETs are well differentiated, NECs are poorly differentiated.  Important difference at Grade 3.
      3. Aggressiveness – Most NETs tend to be indolent or slow growing while NECs tend to be aggressive and faster growing. However, Ki67 and/or mitotic count is an aggressiveness measurement tool.  Genetic profiles can also be a guide but this is beyond the purposes of this article but may be explored in subsequent parts.  It follows that NECs normally have a worse prognosis in comparison to NETs.
      4. Hormone Secretion – NETs can produce peptide hormones that may be associated with hormonal syndromes.  NECs usually fail to express hormones or produce hormonal syndromes.
      5. Somatostatin Receptors – A NET is much more likely to express somatostatin receptors which can influence treatments such as somatostatin analogues and peptide receptor radiotherapy (PRRT)
      6. Hereditary Syndromes – NETs are much more likely to be associated with hereditary syndromes such as Multiple Endocrine Neoplasia (MEN).
      7. Platinum Based Chemotherapy – NETs are less likely to show a good response to platinum based chemotherapy which can often be the first line treatment for NEC.
      8. Primary Locations – can be vastly different in terms of commonality and therefore provide clues to investigators. Common locations for NEC include: Lung, Esophagus, Colon, Urogential Organs and Skin –  with the exception of Lung, these are very rare locations in NETs.  Conversely, rare/very rare locations for NEC but common in NET include: Rectal, Small Intestine, Appendix, Stomach, Pancreas.

Summary

I intend to cover more on Grade 3 tumours going forward and a ‘Part 2’ article will follow covering treatment differences, genetic profiles and unmet needs.

Clinical Trial: Treatment of IBS with diarrhoea – titrated ondansetron (TRITON)

I was never diagnosed with Irritable Bowel Syndrome (IBS) but sometimes I feel like I now have it.  I know many others feel the same way.  But when I look at the alternatives, I can’t help thinking it’s a small price to pay given that one of them might be a slow degrading quality of life until shuffling off  this mortal coil. If I had the choice again, I would still take the surgery.

Before the article continues, let me be clear – I’m not suggesting this is a potential treatment for NET patients with post abdominal surgery side effects or side effects of any other treatment, nor am I suggesting it’s a potential treatment for those with carcinoid syndrome diarrhea.  I publish it because there is a connection to serotonin and it may be a useful read for the more curious amongst us. In fact, since publishing I’ve been contacted by several people telling me they are aware of the drug having been treated with it for nausea.

I once wrote about IBS in an article entitled “Were you irritated by your misdiagnosis” (click the link to read).  This was written after I completed an online IBS course.  I wrote the article in a balanced way in an effort to explain why many patients are misdiagnosed with IBS in the lead up to the correct diagnosis some time later.  This is an issue with other conditions, not just NETs.  It was also designed to capture IBS readers and offer them a chance to review their diagnosis to ensure there wasn’t anything else they might try to double-check (markers and scans mainly).

A new drug on trial for IBS

Given the connection between NETs and IBS, I was really interested to see this in a UK national newspaper and I subsequently researched for some formal papers to back up the headline.  What I found most interesting was the suggestion that a drug designed to inhibit serotonin was involved (…… but read on rather than get too excited).

Diarrhea – the IBS and NET Effect

Diarrhea is a big feature of IBS although there are several types including diarrhea mainly, constipation mainly and a mixed of both – you can read more in my IBS article linked above.   Diarrhea is also a big feature of several of the NET Syndromes, in particular Carcinoid Syndrome.  It is known that the cause of carcinoid syndrome diarrhea is the oversecretion of serotonin.  This makes is quite distinct from other reasons for diarrhea, including but not limited to side effects of intestinal surgery (as one example).

Clinical Trial: Treatment of IBS with diarrhoea – titrated ondansetron (TRITON)

What is ‘ondansetron’. It’s actually a powerful anti-sickness drug given to cancer patients and some of you may recognise it as ZOFRON.  Interestingly it’s a serotonin receptor (5-HT3) antagonist (5HT3-RA) for antineoplastic chemotherapy-induced nausea and vomiting. Ondansetron is a drug which blocks the 5-HT receptor, which is used to treat nausea and sickness, and has an excellent safety record.  Other 5HT3-RAs include Tropisetron, Granisetron, Dolasetron, Palonosetron, Ramosetron (the group of drugs in the class known as 5HT3-RAs are known a ‘setrons’).

It is being offered to those with irritable bowel syndrome (IBS), helping to ease the most embarrassing and painful symptoms of the condition.  According to the Daily Mail, if the trial is successful, it could throw open the doors to the first targeted treatment for the millions of IBS patients with bloating, abdominal discomfort and urgent bowel movements. Two people on the trial are featured in the newspaper article reporting good outcomes.

Information on the Trial.  Researchers are hoping to recruit 400 volunteers in the UK aged over 18 who have IBS to take part in the 12-week study.  You can read more about the trial in the reference documents below.

Read more here:

1. The Daily Mail article. Click here.
2. Trial Sponsor site.  Click here.
3. Clincial Trial Document.  Click here.

Would this work for carcinoid syndrome diarrhea?

I guess many of you will now be thinking that but I advise not to get too excited as things are never that straightforward.  However, if I was a pharmaceutical involved in NET research, I would certainly be watching this trial carefully.  None of us know the interaction between NETs, NET treatments and titrated ondansetron and its mechanism of action. It may be more directed at brain and central nervous serotonin rather than gut serotonin which is mainly the issue with carcinoid syndrome diarrhea, i.e. it may not work in the same way and/or have the same effect as other approved NET drugs such as somatostatin analogues (Octreotide/Lanreotide) and tryptophan 5-hydroxylase (TPH) inhibitors such as XERMELO.

Still, it’s an exciting trial.

I will keep this article live for any developments.  Finally please note this is not in any way medical advice and not a recommendation to try these drugs to control your diarrhea.

I’m not sick, I just have cancer


im not sick^J I just have cancer

Opinion. I receive many messages from people across the world. Recently, one person asked me if I saw myself as a sick person. I found it a really interesting question because someone with cancer must be sick, right?

When I was diagnosed, I really didn’t feel unwell, not enough to consider myself a ‘sick person’. Prior to that, I suppose like everyone else on the planet, I had normal day-to-day stuff come along but that always settled in days or weeks. But never enough to call myself a sick person other than as a temporary label. Quite often I would ignore the illness and continue working and also continue normal day to day activities. In hindsight, some of these issues might have been connected to my cancer but that’s the nature of medicine sometimes. I try not to reflect too much on what might have been.

Even after diagnosis of advanced and incurable cancer, I still didn’t feel unwell and continued to work and go on holiday. Chris and I jetted off eight weeks after the diagnosis, there was a nice gap right in between starting daily octreotide and a liver embolisation. OK the subsequent procedures and surgeries I had were tough and I guess if you looked at me lying in a hospital bed with a dozen pipes going in and out of my body, you would quite rightly assume I was a sick person. But as I said above, it’s only ever been a temporary label because when I was stronger, I went back to work, continued going on holiday and continued going about my life in a relatively normal fashion. I’m not special or unique as millions of cancer patients do something similar. Sure, I made changes, but sick or not, don’t we all make adjustments to suit changes in circumstance?

Despite the furore that erupts in reaction to the ubiquitous invisible illness clichés we see, I don’t really mind ‘looking well’, I mean who wants to look unwell? I’m very happy to look well, and very happy to feel well. I’m not seeking pity or victim status by demanding people to say that I have to look unwell simply because I have cancer. While we’re on the subject of labels, I have cancer but please don’t call me a ‘sufferer’ – I’m far from being a sufferer, an old-fashioned term for those with illness and I’m thankful to see less use of the term today.

I can’t undo my diagnosis of advanced and incurable cancer and I refuse to retreat into a corner feeling sorry for myself. After all, I’m not a sick person just because I have cancer, I can still get on with living my life.

Rosacea – the NET Effect


Rosacea The NET Effect

Around 2001, I started noticing some issues on my nose, particularly around the creases, an issue I still experience today.  It normally starts with a stinging feeling, an indication I’m about to experience some sort of inflammation. What eventually happens is something which looks like a ‘whitehead’ which I now know to be a ‘pustule’.  Sometimes there are multiples and most are not normally bigger than 2mm, mostly smaller. These pustules nearly always disappear within a short period of time, normally after washing/showering but they tend to leave reddish marks which eventually fade.  Very infrequently, these pustules would appear on my chin.  After 18 years of the issue, my nose is slightly discoloured and more reddish than the rest of my face.

Shortly after I started experiencing this issue, a doctor diagnosed me with ‘mild rosacea‘. If this is a correct diagnosis, then I would appear to have Subtype 2 or papulopustular (acne) rosacea (see breakdown of types below).  I also have the minor irritation of a recurrent mild eczema inside my right outer ear which has run parallel to this issue (…. spookily).

For around two years, I was treated with a mixture of low dose oral antibiotics (tetracycline) and a skin medication known as metronidazole. This did clear up the issue but it always returned and I stopped the medication opting instead for a commercial product which I find works better.  It doesn’t clear it 100% but I’ve learned to live with it and it is a long-term chronic condition.  I looked at many Rosacea sites online and none of the pictures seemed to apply to me and I agree with my diagnosing doctor in terms of a ‘mild’ version.

I worked out early on that the triggers were stress, when ‘run down’, and too long in the sun. There were possibly others.  Stress was part and parcel of the work I was involved in and it was at a time when I left my life in the military after 29 years and started a second career in industry (often I think in hindsight, I may have been overly stressed at the life change without realising it).  Without any medical input, I decided to try to make sure I got sufficient vitamins and I now appear to get less coughs and colds then I used to.  I now try to stay out of the direct sun.  Other common triggers are listed on reputable sites andinclude alcohol, hot and cold weather, exercise, hot baths and spicy foods.

What is Rosacea

A common skin condition, usually occurring on the face, which predominantly affects fair-skinned but may affect all skin types in people aged 40 to 60 years old. It is more common in women but when affecting men, it may be more severe.  It is a chronic condition, and can persist for a long time and, in any individual, the severity tends to fluctuate. Rosacea tends to affect the cheeks, forehead, chin and nose, and is characterised by persistent redness caused by dilated blood vessels, small bumps and pus-filled spots similar to acne. There may also be uncomfortable inflammation of the surface of the eyes and eyelids.  I found this site to be a very useful Rosacea reference.

Rosacea is sometimes classified into 4 subtypes that may overlap:

  • Subtype one, known as erythematotelangiectatic rosacea (ETR), is associated with facial redness, flushing, and visible blood vessels.
  • Subtype two, papulopustular (or acne) rosacea, is associated with acne-like breakouts, and often affects middle-aged women.
  • Subtype three, known as rhinophyma, is a rare form associated with thickening of the skin on your nose. It usually affects men and is often accompanied by another subtype of rosacea.
  • Subtype four is known as ocular rosacea, and its symptoms are centred on the eye area.

What causes rosacea?  

The cause of rosacea is not fully understood. Your genetics, immune system factors, and environmental factors may all play a part. Factors that trigger rosacea cause the blood vessels in the skin of the face to enlarge (dilate). The theory that rosacea is due to bacteria on the skin or in the gut has not been proven. However, antibiotics have proven helpful to treat rosacea. This is because of their anti-inflammatory effect. Rosacea is not contagious.

Why is rosacea sometimes linked to NETs?

On certain sites and in certain texts about NETs, you will see mention of Rosacea, clearly as a misdiagnosis of someone who presents with flushing.  I started experiencing the sensation of NET related flushing in late 2009/early 2010 and I can honestly say this was a totally different experience to what I had with my mild rosacea. However, I don’t have the ‘blushing’ type of rosacea and I can see the presentational similarities.

Another issue commonly reported in both conditions is small visible blood vessels on the face, known formally as Telangiectasia or informally as ‘spider veins’ or ‘broken capillary veins’. This is quite common with erythematotelangiectatic rosacea (subtype 1).  I actually have at least two of these showing and this appears to be something I’ve only noticed since NET diagnosis and only in the last few years.  Interesting it says this is something normally caused by “chronic flushing” but I wouldn’t have labelled by flushing in that way. I have not felt any flushing since late 2010 after surgery and commencement of long acting somatostatin analogues.  Unless there has been something ‘sub-clinical’ going on, I’ve veered my minor issue towards long-term but mild rosacea as the cause rather than NETs.  Telangiectasia is mentioned in many NET texts including my own article “Neuroendocrine Cancer: A Witch’s Brew of Signs and Symptoms”

Histamine if often linked to both conditions.  Read about NET related histamine here and Rosacea histamine issues here.

Summary

I’ll be honest with you, I’m actually not 100% convinced I have rosacea as it has similarities with many other skin conditions. In fact, skin issues are pretty common with NET patients, some are actually directly linked to NETs including Merkel Cell Carcinoma,  pellagra (linked to Carcinoid Syndrome) and Sweet’s syndrome (linked to Glucagonoma).  In addition, many people develop skin issues as a side effect of treatment.  Read more here.

Neuroendocrine Cancer: No one gets it until they get it


Over the years of my advocating, I’ve tried to explain Neuroendocrine Cancer to many people outside the community.  Some ‘get it’ but many don’t.  Most understand ‘Cancer’, they have real difficultly understanding ‘Neuroendocrine‘.  Despite how hard I try, I can see that some of them just don’t get it!

One of the challenges of explaining Neuroendocrine Cancer is the sheer complexity and spectrum of types. It’s a heterogeneous grouping of cancers ranging from some quite indolent versions through to very aggressive versions similar to many dangerous adenocarcinomas.  Unlike many of the more understood cancers, Neuroendocrine Cancer can literally appear anywhere in the body, adding to an already complex description, in addition to creating a disadvantage of awareness opportunities because of the use of incorrect cancer types, clearly many doctors and media organisations don’t ‘get it’ either!

Add in the symptoms caused by Neuroendocrine Tumours and their associated ‘Syndromes‘ and ‘Hormones‘, the external audience is now falling asleep or lost interest. Trying to explain why these diseases cannot be diagnosed earlier is also very complex.  “How can it be so difficult” many of them ask.

If you have managed to keep their interest and get onto the subject of living with the disease, it gets even more mind-blowing.  Non-stop surveillance, lifetime surveillance, permanent side effects of treatment. “No way” many of them remark.  The problem is that many people have a really simple outlook on cancer; something goes wrong, you get diagnosed, you get treated, you either die or live.  Simple isn’t it?

One group that normally ‘gets it’ is those who have currently got it, i.e. Neuroendocrine Cancer patients and their close families and supporters.    They may not ‘get it’ before someone is diagnosed and they may still not ‘get it’ once someone is diagnosed, but they eventually will ‘get it’. I have many people who ‘get it’ in my private group and on my main campaign sites.

Despite the difficulties, I’ll continue talking to those who have not yet ‘got it’ hoping to make them understand the disease.  I also intend to continue to help with the undiagnosed (some of these guys probably do ‘get it’ but just not yet formally ‘got it’).  I also want to help those at and beyond diagnosis who despite having it, don’t yet quite ‘get it’.

No one gets it until they get it. It shouldn’t be that way.

From dying to living, to hell and back


I once wrote a post about patient stories, in particular the ones I receive in my private messages.  The headline was “The shock effect never wears off“.  But none have been more shocking than the one I received early in 2019.  (edit: After posting this article, I heard of a few similar cases).

This is a story about someone who is a private person but felt the need to reach out to me about their diagnostic experience. This person wanted to talk about it, but in private and I was happy to listen.  I was so moved by this story, I persuaded this person to let me tell it here whilst retaining their anonymity.  Hence referral going forward as ‘Patient E’. I just felt that someone somewhere might learn something very important.

The Story of ‘Patient E’

In December 2018, Patient E was told ‘Stage 4 Pancreatic Cancer’ and had 10 months to live. Chemo was to be attempted in January in an effort to extend life but in the meantime was told to spend Christmas for the last time with the family, a spouse and 3 young children.   On 2nd January, Patient E was then told (with apologies) it was actually a ‘Neuroendocrine Tumour with a pancreatic primary’.  The only good thing about this story so far, is that they told the children nothing over Christmas. “Why worry happy little people” was the bit of the story which brought out my tears.

Initially I was quite angry this could happen to anyone but I was then calmed by Patient E who now had fresh hope and optimism, perhaps realising that there were possibilities for many more years with the family.

The Story of ‘Patient F’

In March of 2017 I was having bad indigestion and since I already had two cardiac stents went to a local hospital to make sure I wasn’t having cardiac issues. They found a mass on the pancreas and metastasis to the liver. I saw a surgeon a couple of days later and he told me it was inoperable, adding that I should pretty much get my affairs in order. A biopsy was then carried out confirming it was neuroendocrine and we were thrilled. I then received a call a couple of days later, saying they had it wrong, it was not neuroendocrine and they wanted to start chemo ASAP! I then received a further call a few days later, saying they were not sure and needed to do more tests. We then went a different hospital where two different surgeons said that it was inoperable. One oncologist said she did not know; and another thought it might be a combination of the two. At this point. they sent my slides to a NET specialist hospital for their opinion, coincidentally we had already scheduled an appointment there. When we walked into this appointment, the NET Specialist greeted us with a big smile and hug, saying that that both she and the surgeon had reviewed my slides; and that it was definitely neuroendocrine – they could operate. Two weeks later the surgeon removed the mass from my pancreas and my spleen. He said that it was probably there for years and looked like it was ready to burst. I was unbelievably lucky.

So why do these things happen?  Apart from the serious communications lapse by the hospitals, this is another example of the problems we as a community face with the anatomical approach many doctors take with cancer, with some even describing a pancreatic Neuroendocrine Tumour as a type of Pancreatic Cancer (this happens with other parts of the anatomy too).

Patients E and F are not alone, I once wrote a story about rock star Wilko Johnson (of Dr Feelgood fame) who was given a very similar prognosis.  However, Wilko was in the later stages of his life and decided instead of undergoing gruelling chemotherapy, he would forego any treatment and tour with his band in the final 12 months of his life and …….. make an album with Roger Daltrey of The Who. It wasn’t until someone enquired why he wasn’t dead after 12 months, that they re-checked and changed the diagnosis to Neuroendocrine Tumour with a pancreatic primary.  Read the whole story here.

I wonder how many other times this has happened.

Neuroendocrine Tumours with a pancreatic primary (pNET) is a totally different cancer to Pancreatic Cancer.  With Pancreatic Cancer, most people die, quite the opposite with pNETs where most people live.  Read more about the main differences here.

I’m grateful to Patients E and F for contacting me to let me know that my blog and my other support sites have been helpful in the transition from despair to hope since finding out the correct diagnosis. I do hope Patients E and F will keep me updated.

“I Knew There Was Something Wrong, But I Didn’t Know What” — A Nurse Shares Her Cancer Story


Judy Golz is a retired registered nurse — she’s also a neuroendocrine cancer survivor.  Like many nurses who get cancer, their experience in working in the healthcare industry possibly helps get a quicker diagnosis, possibly because they can recognise symptoms and likely differential diagnoses and it possibly helps knowing how the healthcare system works.

But with uncommon and complex diseases, it’s not always that straightforward, even for a nurse or any other healthcare professional.  But Judy makes an excellent point about the quantity and quality of medical information now out there, including for Neuroendocrine Cancer and suggested she would be in a better place for self-diagnosis today.

Two things spring to mind about this story. Neuroendocrine Cancer is such a complex disease, it can often be hard for healthcare professionals to diagnose themselves.  Secondly, since my diagnosis in 2010, there is no doubt a lot more information out there and I’d like to think I’ve played my part in that.

Watch her video by clicking here.

Great job Judy Golz and SurvivorNet.

Letter from America

letter from america envelope

I’ve always been one to keep an eye out for the postman (the postie as we say here). Even as a heavy user of computers, I still get excited about receiving ‘paper’ mail.  Other than birthday cards, I personally don’t tend to see many handwritten letters nowadays. In today’s internet connected world, handwritten letters are always exciting, always special. However, the one I received in the first week of February 2019 was extra special, it was postmarked from North Carolina USA.

Now ….. for those around the same age as me, you might have been attracted by the article header and have remembered the famous radio show entitled “Letter from America”.  This was a weekly fifteen minute speech radio series broadcast on BBC Radio 4 and across the world through the BBC World Service. Throughout its history, it was presented by Alistair Cooke, who would speak of a topical issue in the US, tying together different strands of observation and anecdote and often ending on a humorous or poignant note. The series ran from 24 March 1946 to 20 February 2004, making it the longest-running speech radio programme hosted by one individual in history! The BBC has archived many episodes on their website and you can actually now listen to these – click here if you fancy a trip back in time.  For me, the memories of the programme were around the deep bond of friendship and shared values that the two great countries share, thus why the radio programme was so special and so relevant to listeners this side of the pond.

Some of you possibly thought about the Scottish duo composed of twin brothers Charlie and Craig Reid – ‘The Proclaimers’. I guess many people in North America and the Southern Hemisphere will be aware of this group who are probably more famous for their anthem song ‘I’m gonna be (500 miles)’ but their song ‘Letter from America’ was actually their most successful.   I have a theory that when people from America tell me they like my quaint British accent, what they actually mean is my Scottish ‘twang’, just like ‘The Proclaimers’ who were born and raised not far from my home town of Dundee.  Their singing style is with a Scottish ‘twang’ – always worth a listen (click here).

Anyway, back to the actual letter.   The person who sent me the letter placed their name and address on the front of the envelope but it was not a name I recognised.  However, he left a clue inside indicating a mutual connection (WEGO Health).  What a boost this letter gave me!

It should also be a boost for all those who read my stuff and follow me on social media because ‘Josh’ is not a Neuroendocrine Cancer patient but he made some really awesome comments which I wanted to share with you. I also wanted you to know first hand that others are being made aware of Neuroendocrine Cancer and our fight for more awareness.

In case you can’t read the handwritten words or wanted to translate, I’ve extracted below:

“Dear Ronny, I just wanted to send a quick “Hello” and “thank you” for everything you do. I’ve become familiar with your advocacy work over the past couple of years and it is hard to find the quality of content and mix of science, lifestyle and hope that you consistently show the world.  It is refreshing and inspiring to say the least. I hope you realize the positive impact you have on real people.  Thank you again and I look forward to your future work.  Sincerely……… Josh”

Letter from America

Thanks for listening

Proton Pump Inhibitors – the NET Effect


Proton pump inhibitors (PPIs) reduce the production of acid by blocking the enzyme in the wall of the stomach that produces acid. Acid is necessary for the formation of most ulcers in the oesophagus, stomach, and duodenum, and the reduction of acid with PPIs prevents ulcers and allows any ulcers that exist in the oesophagus, stomach, and duodenum to heal. PPIs are prescribed to treat acid related conditions such as:

  • Esophageal duodenal and stomach ulcers
  • NSAID-associated ulcer
  • Ulcers
  • Gastroesophageal reflux disease (GERD)
  • Zollinger-Ellison Syndrome – ZES (note this is a syndrome associated with a functioning duodenal or pancreatic NET known as a Gastrinoma)
  • They also are used in combination with antibiotics for eradicating Helicobacter pylori, a bacterium that together with acid causes ulcers of the stomach and duodenum for eradicating H. pylori, a bacterium that together with acid causes ulcers of the stomach and duodenum.

Although this should not be considered a full list applicable to all countries, the drugs tend to be prescribed or purchased under the following names:

  • Aspirin and Omeprazole (Yosprala)
  • Dexlansoprazole (Dexilent, Dexilent Solutab)
  • Esomeprazole (Nexium, Nexium IV, Nexium 24 HR)
  • Esomeprazole magnesium/naproxen (Vimovo)
  • Lansoprazole (Prevacid, Prevacid IV, Prevacid 24-Hour, Zoton FasTab)
  • Omeprazole (Prilosec, Prilosec OTC, Losec, Mepradec)
  • Omeprazole and sodium bicarbonate (Zegerid, Zegerid OTC)
  • Pantoprazole (Protonix, Pantoloc Control)
  • Rabeprazole (Aciphex, Aciphex Sprinkle, Pariet)

PPIs have revolutionized the management of acid-related diseases and there is evidence supporting their superior efficacy and overall safety profile. Unfortunately, it would appear this has possibly led to their overuse and inappropriate use. When used appropriately, the overall benefits significantly outweigh the potential risks in most patients.

One US pharmacist magazine has stated that almost half of all patients taking a PPI do not have a clear indication. It follows that PPIs may not be the appropriate treatment for many people. The American Gastro Journal nicely covers this issue – click here.

What is the connection with NETs?

Millions of people will have been prescribed these drugs for the various reasons listed above and as I said above quoting from a reputable US Pharmacist magazine, perhaps many do not have a clear indication for their use. So this issue is much wider than NETs.

Above, you can see a direct link to duodenal/pancreatic NET syndrome – ZES. However, there is also a known link between the use of PPIs and the effect on the Chromogranin A blood test, the most common tumour marker used in the diagnosis and surveillance of many types of NET. Several studies have concluded that PPIs falsely elevate Chromogranin A but there is another option – read more here.

Any other risks of using PPIs?

There are several well-known risks of using PPIs in the long-term. However, many drugs have side effects, often the risks of not taking a particular drug can be outweighed by taking it. I will not comment further but leave you with some references to read yourself:

1. From the UK National Health Service (NHS). They took a balanced view adding the risk element I described above. Importantly they stated that PPIs are not usually intended to be taken long-term. Read more here. The British Medical Journal (BMJ) published the study referred to by the NHS here.

2. The NHS also published an article based on the results of a US study. Again, they indicated the study had similar limitations to the one above. Read more here (links to the study contained within).

3. There are literally dozens of similar articles but most seem to point to these two studies. However, it should also be noted that the US FDA has issued safety warnings about long-term use of PPIs. This is covered in the aforementioned US Pharmacist magazine article here.

Are there alternatives to PPIs?

Firstly, you should NEVER stop taking PPIs without speaking to the doctor who prescribed them.

There’s a class of drugs known as Histamine H2 Receptor Antagonists (H2RA) that reduce the amount of acid produced by the cells in the lining of the stomach. They are also commonly called H2 blockers. They include Cimetidine (Tagamet, Tagamet HB), Famotidine (Pepcid, Pepcid AC), Nizatidine (Axid) and Ranitidine (Zantac). Brand names may differ from country to country. From what I read, they are not as powerful as PPIs but for some people they may prove adequate. Read more about H2 blockers here.

So I can just stop taking PPIs and start taking H2 blockers?

NO. As I said above, you should never discontinue a prescription for PPI without talking to your doctor. However …. it’s not common knowledge that suddenly stopping PPIs is not a good idea – you must gradually reduce (i.e. taper off).

Why taper? PPIs block the production of acid in your stomach which can help with the symptoms but that also turns on the release of gastrin. This is not ideal for two reasons according to NOLANETS:

  1. When you try to get off of PPI, the gastrin stimulates acid production and stays elevated, potentially for several months (depending on how long you were on the PPIs). This makes your reflux worse than before and makes getting off of this medication very difficult. Gastrin also stimulates Chromogranin A thus why this can be elevated in patients who have been taking PPIs.
  2. Gastrin also acts like a growth factor and stimulates the growth of ECL cells (enterochromaffin like cells). Clearly this does not happen to everyone on PPIs. However, and as per the NHS advice above, PPIs should not be considered a long-term solution except for conditions for which they are clinically indicated (e.g. Barrett’s oesophagus, Gastrinoma (Zollinger Ellison Syndrome).

What are NET Specialists saying about this?

The best source of information on this seems to be in two main areas:

1. One is NOLANETS (Dr Eugene Woltering et al) who appear to be leading the way on identifying those who may have a clinical indication for use of H2 blockers rather than PPI and this NET Specialist organisation has produced a sheet showing how to taper people off the drug and onto the less risky H2 blockers. Read the NOLANETS “Get off PPIs” Sheet by clicking here. They state that PPI use increases circulating gastrin which in turn increases the amount of acid in the stomach. The increase in gastrin also stimulates the enterochromaffin like cells (ECL) of the stomach to produce Chromogranin A and this explains why it can be elevated in PPI users. The US Pharmacy magazine quoted above, appears to confirm this thinking.

2. The European NET Society (ENETS) discusses the issue in their guidelines but only in relation to Zollinger-Ellison Syndrome (ZES). This is a direct quote from ENETS 2016 Guidance – “The widespread use of PPIs is a major problem for the diagnosis of ZES because these drugs have an extended duration of action (up to one week), they cause hypergastrinemia in 80-100% of all normal subjects, and can confound the diagnosis. Furthermore, if PPIs are abruptly stopped in a true ZES patient, anti-peptic complications can rapidly develop, and therefore some expert groups have recently recommended that the diagnosis of ZES should be established without stopping the PPIs or by attempting to taper the dose. Unfortunately, as suggested in a number of recent papers, in most patients, the diagnosis cannot be easily established without an interruption of the PPIs. Furthermore, a secretin test cannot be used while a patient is taking PPIs because it can result in a false positive test. Other tumour markers such as serum chromogranin A were found to be not reliable for the diagnosis of ZES patients, as up to 30% have normal plasma chromogranin A levels. PPIs also lead to increased chromogranin A levels on their own. It is therefore recommended that if the diagnosis is unclear, the patient should be referred to a centre of excellence and if this is not possible, PPI withdrawal should be cautiously performed (in an asymptomatic patients with no active acid-peptic disease or damage) and with adequate cover by H2 blockers and careful patient monitoring”.

PPIs and PERT

I have anecdotal evidence that people are being prescribed PPIs alongside Pancreatic Enzymes Replacement Therapy (e.g. Creon, Nutrizym etc). While most types of PERT are gastro-resistant, a high acid environment may impair their efficacy. The rationale behind using PPI (or H2 blocker) is to decrease the acid level and allow the PERT to work better. Given the research behind this article, I would certainly challenge the use of PPI alongside long-term use of PERT.

Summary

The aim of this article is not to scare anyone, I’ve been careful with the sources, quotes and facts. Like anything in life (including the medical world), there are risks and knowing about them allows us to manage these risks in conjunction with our doctors and healthcare specialists. If you are concerned about anything you find inside this article, I suggest you speak directly to your doctor/specialist for advice.

Personally speaking, I would like to see more from the NET Specialist community on this issue.

Clinical Trial: Lenvatinib Efficacy in Metastatic Neuroendocrine Tumors (TALENT)



Lenvatinib has just completed a Phase 2 trial in Gastrointestinal (GI) and Pancreatic Neuroendocrine Tumours.  The trial was sponsored by Grupo Espanol de Tumores Neuroendocrinos (Spanish NET scientific organisation) and the manufacturers.  A European venture with sites in Austria, Italy, Spain, UK.   Headline: The responses are better than Everolimus (Afinitor) and Sunitinib (Sutent).

What is Lenvatinib?

It is a type of targeted therapy known as a multikinase inhibitor. The brand name is ‘LENVIMA‘. These work by inhibiting multiple intracellular and cell surface kinases, some of which are implicated in tumour growth and metastatic progression of cancer, thus decreasing tumour growth and replication. A range of receptor kinases are involved in these processes, including vascular endothelial growth factor receptor (VEGFR), platelet-derived growth factor receptor (PDGFR), stem cell factor (c-KIT), Flt3, fibroblast growth factor receptor (FGFR), which can be hyperactivated during tumour formation and progression.  Tumour growth may be prevented by inhibiting the action of these hyperactivated receptor kinases, and as tumour progression usually involves the action of multiple kinases rather than just one, it is logical to target multiple kinases.

The Lenvantinib mechanism of action is similar to targeted therapy drugs already in use (or in trial) for Neuroendocrine Tumours:

  • Sunitinib (Sutent) – a targeted therapy receptor protein-tyrosine kinase inhibitor.  It inhibits the actions of vascular endothelial growth factor (VEGF) and is an angiogenesis inhibitor (i.e. the development of blood vessels to supply the tumour with nutrients, which they need to grow).  It is a mutlikinase in inhibitor.
  • Everolimus (Afinitor) – a targeted therapy kinase inhibitor that inhibits mammalian target of rapamycin (mTor) kinase, an enzyme required for cell growth and survival. By blocking this enzyme, the medication prevents cell division and, in turn, tumor growth. The medication can also interrupt angiogenesis.
  • Cabozantinib, an oral potent inhibitor of vascular endothelial growth factor receptor 2, MET, and AXL, and currently on trial for Neuroendocrine Cancer.  Click here.

Multikinase inhibitors such as Lenvatinib, may be used to treat advanced kidney cancer as well as other specific types of cancer (in my research I also noted that in addition to kidney cancer, the drug is already approved for liver and thyroid cancers).  Worth also noting that the 3 examples of targeted therapy above are not just in use/in trial for Neuroendocrine Cancer, they are also in use/in trial for others including Renal (Kidney) Cancer, Breast Cancer.  Often more than one single kinase inhibitor can be given as a combo treatment, perhaps in sequence, to tackle multi kinases.

Anything special about Lenvatinib for Neuroendocrine Cancer? 

Recent reports from oncology conferences indicate that Lenvatinib showed significant antitumor activity and a favourable toxicity profile in progressive advanced NETs. This is the highest reported ORR with a targeted agent, confirmed by central radiology assessment in pancreatic NETs and Gastrointestinal (GI) NETs with promising progression free survival (PFS) in a pre-treated population; further evaluation is warranted.

Adverse events were mild to moderate in 90% of patients, the most frequent being fatigue, diarrhea and hypertension.

Lenvatinib showed the highest reported overall response rate (ORR) by central radiology assessment with a targeted agent in advanced NETs:

Average 29.2%

pNETs: 40.4% (95% CI 27.3-54.9),

GI NETs: 18.5% (95% CI 9.7-31.9.

Worth noting that Everolimus and Sunitinib were approved with ORRs much less than these figures.

What’s next? 

Given the responses in comparison to other approved targeted agents, a phase 3 trial should be anticipated.  Studies are “currently ongoing” and “further evaluation warranted”.  I will keep this article live to provide updates.

New Trial using Lenvatinib and Everolimus in Treating Patients With Advanced, Unresectable Neuroendocrine Tumors

Under ClinicalTrials.gov Identifier: NCT03950609, there is a trial being setup at MD Anderson in Texas USA.  Use of a combo of Lenvatinib along with Everolimus (Afinitor) in treating patients with advanced, unresectable Neuroendocrine Tumors (the word ‘Carcinoid’ is used in the trial documentation).

Clinical Trial: Intra-arterial Lu177 (PRRT) for Neuroendocrine Cancer liver metastases (LUTIA)

The treatment of liver metastasis is a common approach following a metastatic diagnosis or discovery of liver metastasis downstream via re-staging. In addition to surgery, there are several liver directed therapies available via embolization techniques. This comes in several flavours:

1. Bland liver embolization – a minimally invasive technique which simply blocks the blood supply to the liver tumours in an attempt to reduce or kill those tumours. Sometimes called Hepatic Arterial Embolization or HAE.

2. Chemotherapy liver embolization – as above but adds in some cytotoxic chemo to the mix. Sometimes called Trans Arterial Chemo Embolization or TACE.

3. Radioembolization is a minimally invasive procedure that combines embolization and radiation therapy to treat liver cancer. Tiny glass or resin beads filled with the radioactive isotope yttrium Y-90 are placed inside the blood vessels that feed a tumour. Often known as Sirtex or SIR-Spheres.

Of course systemic treatment is body-wide and so includes the liver as a target. Systemic treatment includes (but is not limited to) Lu177 (PRRT), Chemotherapy, Targeted Therapies such as Everolimus (Afinitor) and Sunitinib (Sutent). Also included are somatostatin analogues such as Lanreotide and Octreotide.

Sometimes systemic treatment is not fully effective on all metastases and although PRRT response rates are good, often patients still live with the burden of remnant liver tumours once therapy is finished.

Doctors in the Netherlands are looking at a trial using Lu177 (PRRT) as a liver directed therapy. The trial is based at 3 sites in the Netherlands and is titled: Intra-arterial Lutetium-177-dotatate for Treatment of Patients With Neuro-endocrine Tumor Liver Metastases (LUTIA). You can read more about the trial by clicking here.

In a clinical trial in USA, the NET Research Foundation is funding similar research at the UCSF Helen Diller Cancer Center led by Dr Tom Hope using Y90 intra-arterial for liver metastasis. See the NET RF’s information here and read more about the clinical trial by clicking here

I will keep this article open for any updates.

Clinical Trial SPARTALIZUMAB – Immunotherapy for Neuroendocrine Neoplasms (PDR001)

THUMBNAIL_CarTcell.jpg

PDR001 (anti-PD-1) is an investigational immunotherapy being developed by Novartis to treat both solid tumors and lymphomas (cancers of the blood).  It is currently being trialled on many cancers including Neuroendocrine.  It’s brand name is SPARTLIZUMAB.

How PDR001 works

PDR001 is a type of immunotherapy, meaning that it acts by activating the body’s own immune system to recognize and fight cancer cells. Normally, an immune system cell called T-cells recognizes and kills infected or abnormal cells, including those that are cancerous. To prevent T-cells from accidentally damaging healthy and essential tissues, however several immune system checkpoints exist to inhibit, or block, them from going about this work. One example is the programmed cell death 1 (PD-1) pathway. Healthy cells produce and display a protein called programmed cell death ligand-1 or ligand-2 (PD-L1 or PD-L2) on their surface. These proteins bind to and activate a receptor called PD-1 that is produced by T-cells. When activated, PD-1 sends a message to the T-cells that prevents them from attacking that particular cell. Cancer cells can hijack this system by producing PD-L1 or PD-L2, effectively hiding from T-cells and evade destruction.
PDR001 is an antibody, a protein designed to interact with and block a specific target. It acts by binding to PD-1, blocking it from interacting with both PD-L1 and PD-L2. This binding blocks the PD-1-mediated inactivation of the T-cells, so that they are able to recognize and target cancer cells. This should result in a reduction in tumor growth and size.

PDR001 in clinical trials

PDR001 has been investigated in multiple completed and ongoing clinical trials, both alone and in combination with a wide range of other agents.

Novartis presented results from an ongoing first-in-human Phase 1/2 clinical trial (NCT02404441) of PDR001 at the American Society of Clinical Oncology (ASCO) meeting in 2016. Preliminary trial results suggested that the drug is well-tolerated and safe, with a similar profile to other anti-PD-1 drugs currently being developed. The trial is still recruiting patients with various types of advanced cancer at 43 sites across North America, Europe, and Asia; more information is available by clicking on its identification number.

Novartis then initiated several dozen other Phase 1, 2 and 3 trials, all registered on clinicaltrials.gov, to continue investigating the safety and anti-tumor activity of PDR001 in a wide range of cancer types, and in combination with other investigational and approved therapies. For example, a Phase 3 trial (NCT02967692) is comparing the safety and efficacy of PDR001 to a placebo, in combination with Tafinlar (dabrafenib) and Mekinist (trametinib), as a treatment for advanced melanoma.

What about Neuroendocrine?

A phase 2, multi-center study assessed the efficacy and safety of PDR001 in patients with non-functional well and poorly-differentiated Neuroendocrine Neoplasms.  According to the clinical trial document, the types of NENs covered are:

  • Well-differentiated Non-functional NET of Thoracic Origin
  • Well-differentiated Non-functional NET of Gastrointestinal Origin
  • Well-differentiated Non-functional NET of Pancreatic Origin
  • Poorly-differentiated Gastroenteropancreatic Neuroendocrine Carcinoma

The clinical trial indicates the trial is active but not recruiting but it would look like they have all the patients needed and are currently analysing the trial data so far awaiting the next phase perhaps.  In fact I have discovered two pieces of evidence from the trial sponsors:

pdr001 results conclusion
Annals of Oncology (2018) 29 (suppl_8): viii467-viii478. 10.1093/annonc/mdy293

In another analysis of the results:  “Patients with well-differentiated advanced NETs were eligible if they had progressed on prior therapy, including everolimus, while the GEP-NEC patients were eligible if they had progressed on one line of chemotherapy. All patients in the trial received spartalizumab via a 30-minute infusion once every 4 weeks until disease progression or unacceptable toxicity.

In the full well-differentiated cohort, there were 7 partial responses (7%), and 55% had stable disease, while 31% had progressive disease. The confirmed objective response rate was 7%, and the disease control rate was 63%. In the GEP-NEC cohort, the objective response rate was 5%, and the disease control rate was 19%.

The thoracic NETs patients fared best with spartalizumab, with limited responses seen in the pancreatic and GI NETs groups; responses seemed to be associated with PD-L1 expression. In the thoracic NETs cohort, two of five PD-L1–positive patients had a partial response. PD-L1 positivity was more common in the GEP-NEC cohort; among 14 PD-L1–positive patients in that group, the partial response rate was 43%.

The most common adverse events regardless of cause included abdominal and back pain, anemia, dyspnea, and hypertension.

Kjell Öberg, MD, PhD, of Uppsala University in Sweden, discussed the study for ESMO. “We have hope,” he said. “We see that maybe there are some tumor types that might respond to immunotherapy.” In general, NETs are considered an “immunological desert.” There is usually very low infiltration of immune cells in these tumors, and there are a low number of genetic mutation events.”

You can also listen to two very well known NET experts (Simron Singh and Jonathan Strosberg) talk about this trial and the drug ……. “the highest response rate was seen in atypical lung neuroendocrine tumors. It was approximately 20%, but in most cases was not durable”.  See the remainder of the discussion by clicking here.

Breath test with the goal of detecting multiple cancers – ready to start trials

breath_test_patient-hero

While it’s a long way off becoming reality, this is quite an exciting clinical trial. I have no idea if it will pick up Neuroendocrine disease but initially, patients with suspected oesophageal and stomach cancers will be asked to try the test. Later it will be extended to include prostate, kidney, bladder, liver and pancreatic cancers. It’s possible that Neuroendcorine tumours in these locations might be picked up or at least show up some abnormality that triggers further checks.

The fact that Cancer Research UK is involved gives me some confidence as they tend to back the strong horses.

I will keep this article live and track developments.

Q-Sphera™ – Next Generation Somatostatin Analogue delivery system?

 

In my article listing the somatostatin analogues and their drug delivery systems pipeline (click here), there has been a very interesting development in a product called Q-Sphera (was previously known as Q-Octreotide).  In a press release, it was announced that an unnamed ‘pharma giant’ has signed a deal with Midatech Pharma Plc that will see it evaluate the latter’s Q-Sphera drug delivery platform.  Later in Feb 2019, the pharma was identified as China Medical System Holdings Limited (based out of Hong Kong).  Adding to the excitement behind this development, it was announced in Mar 2019 that the Spanish Government had conditionally approved a €6.6m loan that will be used to help commercialise this flagship drug.

Midatech’s Q-Sphera™ is an advanced microencapsulation and polymer-depot sustained release (SR) drug delivery platform produced using a novel and disruptive printing based process, with numerous and distinct advantages over conventional reactor based technologies. From a manufacturing perspective Q-Sphera™ is a precise, scalable, efficient, and environmentally friendly microparticle platform. From a clinical perspective Q-Sphera™ ensures monodispersed microparticles that release active drug compounds into the body in a superior linear tightly controlled and predictable manner over an extended period of time from 1 – 6 months.  An injection lasting 6 months sounds very exciting but I have no more detail on the feasibility or likelihood of such a change in frequency with Octreotide or Lanreotide but the press release does mention the possibility, i.e. “Q-Sphera allows drug compounds to be released into the body in a “highly controlled manner” over a prolonged period of time; potentially from a few days to up to six months.”

What’s the main differences?

The current trials are based on the use of Sandostatin LAR (Octreotide) using the Q-Sphera delivery system (previously known as Q-Octreotide). The key aspects of usability are reconstitution and needle size but there is also an inference that less frequent injections could be possible.   A comparison of the trial output is as follows:

  • Reconstitution: For Sandostatin LAR (SLAR)™ the procedure to prepare the product for injection is a complex 30 step error prone process, taking up to 40 minutes and, once reconstituted, the product has to be given immediately to prevent solidifying and wastage of the injection. For MTD201™ Q-Octreotide the preparation process is a simple 5 – 7 minute procedure, after which the product is stable up to 2 hours. For the nurse preparing and giving the injection, the short and flexible process of MTD201™ has clear advantages over the all consuming SLAR process™.
  • Needle size: For SLAR, a large 19G needle is prescribed for the injection to prevent blockage, and often an even large 18G needle is required for successful injection. For MTD201 Q-Octreotide the precision microencapsulation technology means that a much smaller 21G needle can be used, and there are no blockages. Other Q-Sphera products use even finer needles as small as 27G. The importance of this is evident from the first-in-human phase I data where MTD201 had lower injection pain – 8% for MTD201 versus 25% for SLAR™, and much lower injection site
    tenderness – 8% for MTD201 versus 83% for SLAR.

This is an exciting development and I will keep this article live with further information as I receive it.

Neuroendocrine Cancer: a needle in a haystack


needle in a haystack

It’s no secret that Neuroendocrine Cancer can be difficult to diagnose. Although earlier diagnosis is improving (as reported in the SEER database report issued in 2017), there is still a lot of ground to cover. It’s also no secret that certain cancers are difficult to diagnose (NETs is one) and there are a number of reasons why this happens, including but not limited to: – they grow silently, they often produce vague symptoms which can be mistaken for much more common illnesses, and their complexity is not fully understood.

I wanted to cover two different aspects of the problem of finding NETs. Firstly, in finding the primary tumour so that the type of NET can be properly established – this drives the best treatment regime. Secondly in finding all the tumours, as this establishes the correct and most detailed staging declaration – this drives treatment plans and surveillance regimes that need to be put into place.

Hunting Tumours – Primary vs Secondary

It’s really important to determine which tumours are primary and which are secondary (metastasis). There’s a number of ways to help work this out and knowledge of NETs epidemiology studies can help.

Specialist Knowledge – certain things are known about the behaviour of NETs

Specialists and in particular NET specialists will be aware of the vagaries of NETs in terms of what tumours are normally a primary and which are normally secondary and many of the pitfalls involved in working that out. Many NETs will have metastasized to the liver at diagnosis, so whilst it is not impossible to have a primary liver NET, the vast majority of liver tumours found will be secondary (metastases). NET Specialists are more likely to have the experience than generalists. They know that the varying metastatic potential depending on the primary site clearly indicates differing biology and genetics across sites and they know that NETs are indeed a heterogeneous group of tumours. The differences cannot be explained by whether the NET is situated in the foregut, midgut, or hindgut. For example, Appendiceal NET is known to be less prone to metastasis. This may be due to the high rate of incidental findings during appendectomies, or because the appendix is an immunological organ where malignant cells can therefore be expected to be frequently recognized by the immune system.

The majority of the digestive tract is drained by the portal venous system, explaining the dominance of liver metastases in this group of tumours. This also explains our finding that many nervous system and bone metastases originate from NETs in the lungs. Disseminated tumour cells may directly reach the systemic circulation from the lungs, whereas if originating from the midgut region, they need to first pass both the liver and the lungs.

As an example of this heuristic knowledge, one Swedish study indicated that two-thirds of peritoneal metastases will be attributed to Small Intestine NETs (SI NETs). SI NETs and Pancreatic NETs (pNETs) are the most likely to metastasize. The least likely sites to metastasize are the Appendix and Rectum. The same study indicated that in addition to the common metastatic locations of lymph nodes and liver, Lung NETs are more likely to metastasize to the brain and bone than other types. I believe the findings from this study more or less correlates to other information I’ve had access to and also confirms the technical behaviour paragraph above.

Multiple Primary Tumours

With NETs there are two scenarios:

1. Multiple primaries in same organ/location (multicentric). This is fairly common in small intestine (SI NETs), stomach/gastric NETs (gNETs), and also found in Lung and pNETs too. NET experts will be aware of the issue and know to look for the possibility. This is an important point with SI NETs as it’s quite long although held together by the mesentery, so a ‘Mark 1 eyeball’ can be more efficient in finding NETs in this organ than scans.  There is a very well known surgical technique called “running the bowel” where they check the small intestine for signs of other primary tumours – they can do the same with the large intestine.  Additional surgeries due to this lack of knowledge could come with significant morbidity. Multiple ‘nodes’ and ‘lesions’ are common in the thyroid.

2. Multiple primaries in different locations. This is common with Multiple Endocrine Neoplasia (MEN) syndromes (the name gives it away) and these may be metasynchronous. MEN1 for example can have tumours in what is called the ‘3 P’ locations, pituitary, pancreas and parathyroid. Of course MEN guys may also have multiple primaries in the same organ (multicentric).  Read more about MEN by clicking here.

There’s probably a third scenario (for all cancers) and that is multiple primaries with different cancers (i.e a second, third and fourth cancer etc). Synchronous would be really unlucky but metasynchonous is more likely and there are many NET patients with a second cancer.

What else helps find a NET? 

There are many other clues open to those involved in diagnosing a NET:

Patient. Very often the patient plays a big part of determining where the primary and other tumours might be by carefully describing symptoms.

Incidental Finds. NETs are very often found incidentally during trips to the ER/A&E and also during tests for something else. This is particularly the case with Appendiceal NETs and might explain why the average age of a patient is significantly lower in this type of NET.

Blood tests and Hormone Markers. We are not yet in a position where these types of tests can diagnose (but we are moving in that direction). In the case of unknown primaries (CUP), sometimes test results can help to find where some of these cancers started. With NETs, symptomatic patients can often test to confirm an elevated hormone marker which may narrow it down to a specific organ or gland. Read more here.

Scans and Endoscopies. Most cancers of a certain size may show up on conventional scanning such as CT, MRI and Ultrasound. Nuclear scans are now playing a bigger part in finding tumours which betray their location through functional behaviour by lighting up or glowing on these imaging devices. Endoscopies (e.g. gastroscopies, colonoscopies, even gastro intestinal pill cameras can be used) can help but like scans are not foolproof). Generally with NETs, if you can see it, you can detect it. Read more here.

Hereditary Conditions. Around 5-10% of NETs are hereditary in nature, mostly involving the MEN group of syndromes. Many of those people will know they are at risk of developing NETs and their doctors should know the most common locations for primary tumours associated with each gene. So a declared or suspected hereditary syndrome is useful in finding primary tumours if they exist and are proving difficult to find.

Biopsies. “Tissue is the issue”. Pathology can very often give really strong clues as to the type of NET and therefore the likely location of a primary tumour, for example additional tests such as immunostains. Many biopsies will come from secondary cancer (metastases), mostly the liver.  Despite all the potential diagnostic routes above, the place the cancer started is sometimes still not found and this may lead to atypical diagnostic/treatment plans and in certain cases this might even include exploratory biopsies via surgery (invasive/minimally invasive), perhaps combined with opportunistic tumour removal if found during the procedure.

Staging. Simple staging can be given if locations of metastases are known. For example in the case of Liver metastases, the stage is automatically Stage 4. However, the full staging definition relies on knowing distant metastases, loco-regional metastases and the full Tumour/Node/Metastases (TNM) definition (size, spread, etc) cannot be fully complete without a primary. Read more here.

Cancers of Unknown Primary

Cancer is always named for the place where it started, called the primary site. Sometimes doctors can’t tell where a cancer may have started. When cancer is found in one or more places where it seems to have spread, but the site where it started is not known, it is called a cancer of unknown primary (CUP) or an occult primary cancer.

When you look at the ratio of all cancers, the figure for cancers of unknown primary (CUP) is quite startling. Depending on where you look the figure is around 2-10%. That doesn’t seem a lot but when you consider the amount of people diagnosed with cancer, the total figure must be staggering. Interestingly, Cancer Research UK say that 60% of CUP cases are in the over 75s. In another interesting Swedish study, doctors claimed that the rates of metastatic cases were higher with certain NETs than they were in their anatomical counterparts, reinforcing the dangerous and sneaky nature of NETs.

Despite quite advanced scanning and diagnostic testing currently in place, and the extensive knowledge of NET specialists, there can still be reasons for not being able to find the primary tumour:

  • The primary is just too small to be seen and is growing quite slow. Very small cancers might not cause symptoms or be seen on scans. This is a particularly relevant point with NETs.
  • The primary could be hidden in tissue in between different organs causing confusion about the actual primary location.
  • The body’s immune system killed the primary cancer. It’s also possible (but not common) that any secondary cancer (i.e. metastases) is still growing.
  • The tumour has become loose from its primary location and exited the body, e.g. from a wall of the bowel and excreted out in the stool.
  • The primary cancer was removed during surgery for another condition and doctors didn’t know cancer had formed. For example, a uterus with cancer may be removed during a hysterectomy to treat a serious infection.

Summary

I hope this is useful for many NET patients, particularly those who are looking for a diagnosis or looking for a primary tumour.

Neuroendocrine Cancer – at times, it can really be like looking for a needle in a haystack.

Neuroendocrine Cancer Clinical Trial – Lutetium-177 OPS-201 (Satoreotide)

ops 201

What is Lutetium-177 OPS-201?

This is a ‘next generation’ Peptide receptor radionuclide therapy (PRRT) or more specifically the radiopharmaceutical that binds to both activated and unactivated somatostatin receptors which are upregulated on these tumours. There is far higher binding via this mechanism than standard octreotate. The technical name of the radiopharmaceutical is Satoreotide tetraxetan lutetium-177 (author’s note, I’m guessing but it could be a variant of Lanreotide).  It was once named JR11.

What’s the difference to the current approved therapy? 

Conventional PRRT (e.g. Lutathera, Lu177 Dotatate) is based on a somatostatin receptor ‘agonist’ approach, whereas 177Lu Ops 201 Satoreotide is a receptor ‘Antagonist’.  The differences are quite technical but in the most layman terms , the antagonist has the capability of attaching (binding) to more receptors, including those in a ‘resting’ or ‘inactive’ state, spends more time on the tumor than agonist based therapies. The result is a higher number of receptor binding sites and greater tumor uptake.  In addition it is said to show an improved tumor-to-kidney dose ratio compared to 177Lu-DOTA-TATE.

This would also be reflected in the theranostic use of the drug in Ga68 imaging (i.e. Ga68 Satoreotide).

Useful reading:

This presentation from Theranostics Australia

The Clinical Trial

The clinical trial is named “Study to Evaluate the Safety and Preliminary Efficacy of 177Lu-OPSC001 in NETs”.  The protocol involves 3 cycles 8 weeks apart of intravenous Lu-177 OPS-201. All patients will have baseline Ga-68 octreotate imaging performed.

The treatment is available for all NET patients with a histologically confirmed diagnosis of:

  • unresectable GEP NET (Grade I and Grade II according to WHO classification (2010, Annex 01), functioning and non-functioning).
  • unresectable “typical lung NET” or “atypical lung NET” are acceptable (with the exception of Large Cell Bronchial Neuroendocrine Neoplasms and Small Cell Lung Cancers).
  • malignant, unresectable pheochromocytoma or paraganglioma

Patients who have previously had Lu-177 octreotate (e.g. Lutathera) are not eligible. Patients may have had any other treatment including chemotherapy, radiotherapy or Somatostatin Analogues (e.g. octreotide, landreotide).

There are other inclusion and exclusion criteria to be found within the clinical trial document.  The trial is due to compete in May 2022.

Where is the Trial based?  

At the time of writing and according to the Clinical Trial document, Australia (Melbourne and Perth),  Austria (Vienna), Denmark (Aarhus), Switzerland (Basel), UK (Royal Free London).  Two sites are also listed in France (Nantes and Toulouse) but trial document currently marked as not yet recruiting.

I have anecdotal evidence to suggest one more UK site is possible in 2019, Windsor in UK, a private healthcare provider but it will be open to public and private patients.

What about USA?

I also found an additional trial based in Memorial Sloan Kettering New York designed to take a theranostic approach by using  Satoreotide (JR11) for the pre-treatment imaging, e.g. Ga68 satoreotide (JR11) and the 177Lu version for treatment. The clinical trial document indicates this trial is active but NOT RECRUITING and is entitled “Theranostics of Radiolabeled Somatostatin Antagonists 68Ga-DOTA-JR11 and 177Lu-DOTA-JR11 in Patients With Neuroendocrine Tumors”

NET News

1. I supported the annual NET Cancer Day event in my own style, contributing SIGNIFICANTLY to both Facebook and Twitter social media platforms.  My twitter accounts were the biggest contributors to the #LETsTalkAboutNETs and #NeuroendocrineCancer hashtags for several days straddling the 10th Nov and between this and my Facebook account, I accounted for a significant proportion of the data recently published by INCA.   I almost got to my 1 million ‘reach’ on twitter in ONE WEEK straddling NET Cancer Day (see below) – just a wee Scottish guy with a less common disease and a computer. Curiously not mentioned by INCA in their recent newsletter.  So I thought I’d mention it instead.

Mind you, every day is NET Cancer Day on my social media platforms. I push on.

3. Personal NET News

My NET. I still await the output from a meeting with my Oncologist and Surgeon to address the new issues identified my routine surveillance scan and a subsequent Ga68 PET/CT. Fortunately the issues are not classed as urgent at this stage. They have dismissed PRRT as an option at this stage (kept in reserve) and it looks like surgery might be on the cards.  You can read about my Ga68 PET/CT experience here and my fibrosis issues here.  I recently has a Renal MAG3 nuclear scan to determine the efficacy of my kidney function – waiting on results but expecting good news.

  • Please join my 2018 (but perpetual) 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 due to sheer numbers of requests, I cannot accept telephone or video calls on a one to one basis. Please just message me and I will respond – see “Send Message” button when you CLICK HERE. (also please ‘Like’ this page if you have not already done so). On a personal note, please do not send me friend requests on my personal Facebook page, I get so many and want to keep this little area of ‘sanity’ free of NET stuff. I have so many other sites you can contact me on – all inside the newsletter. 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.

Ronny Allan’s Private Facebook Group

As the number of people contacting me has increased so much, it’s becoming very difficult to answer all questions myself. I’ve therefore set up a chat room here (I’m not the only one who can answer questions!). This is not like many forums, it’s a place to make people feel safe and to discuss without many of the other distractions that can be found on forums and is moderated accordingly. I welcome all types of NET, people from any country and I also welcome carers/caregivers and medical people. It’s also a place where I will bring in expertise to chat about various issues. The first online chat was held on 28 Feb about the problems NET patients can have with being unable to produce sufficient digestive enzymes and the treatment to correct this issue PERT (Creon etc).

The second chat will be about “Weight” and you can join the event by selecting ‘Going’ to this event (you will be kept up to date inside this event).
Join the chat group by clicking here (please answer the simple questions so you can be processed quicker). As at 30th November, there were almost 2200 people in the group. It’s the fastest growing group in the world for NETs.

And I’m working on a guest Gastroenterologist for a third chat.  To be confirmed.

New Audiences for NET Cancer

I said it was my aim to find new audiences for NETs rather than just share stuff within our own community. Sharing memes and animal pictures between patients is not my scene – I want to extend awareness much wider than that and with much wider and compelling messages, particularly to the outside world.  Doing that is a way to ensure we move away from being a niche condition that no-one has heard of. I’m doing this all the time, although it may not always be apparent.

Engagements and Invites

  • I just received an invite to help build an educational tool for NETs. More to follow when I am at liberty to tell you.
  • I’m working on a video shoot next week for a Pharma company who are looking at how cancer patients live from day to day.  More info later when I am at liberty to tell you.
  • I’m working on an association with a Pharma company to help with patient portals.  Early days.
  • I’m working on an association with a healthcare company to help with their marketing.
  • I’ve accepted an appointment to the Strategic Advisory Board on MultiMed Inc the owner of Cancer Knowledge Network based in Canada who have featured my articles in the past (https://cancerkn.com/) – They also publishes a magazine called Current Oncology which is Medline listed. This is not a NET site but my inclusion will no doubt raise the profile for us. Read more here.
  • 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’m ‘extremely’ active on twitter and I find a lot of research stuff there, in addition to new audiences. 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 are people regularly retweeting my stuff who do not have a personal interest in NETs and I am now regularly copied in on many tweets by those wishing to use my account as a vehicle for dissemination. In the last month, I tweeted 244 times on my personal account which led to over 117,000 views of my tweets. I was mentioned 203 times by other tweeters, 2331 people looked at my profile (where it mentions NETs) and I gained 64 new followers. My weekly ‘reach’ is consistently between 400,000 and 800,000, heading for 1 million soon. 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. This has been a huge success from my point of view resulting in an increase in blog hits and to a wider population than just NETs. 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 to join over 630 other subscribers.
  • WEGO. I continue to be featured by ‘external’ organisations such as WEGO and my PODCAST is reaching new audiences – click here. In March, I managed to get into a very well contested short list for an article about the use of Facebook for health communities in light of the recent bad press for the service. 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! They recently listed me as one of the top 5 bloggers to watch in 2018. This is great awareness and good feedback for my own efforts. Read more here. I have made the finals in the last 3 years and I was their winner in the 2016 Best in Show: Community and 2018 Best in Show: Blog announced on 26 Sep 2018. Check out my WEGO Health profile here.

An amazing amount of awareness and hopefully, support for others. However, I cannot do this without you guys liking, commenting and sharing! The likes give me motivation, the comments and private messages give me inspiration or at least a chance to explain further – and they also keep me humble. The sharing gives me a bigger platform. A bigger platform generates more awareness.

Remember ….. in the war on Neuroendocrine Cancer, let’s not forget to win the battle for better quality of life


Neuroendocrine Cancer – is normally slow growing BUT …..



I have a lot of be thankful for – I’m still here for starters!


BUT

……… here’s a list of 10 things I’m NOT thankful to Neuroendocrine Cancer for!

Thanks for growing inside me for years before making your vague announcement

Sorry too late, I’m metastatic and around 50% of patients will be at diagnosis (so I’m not alone!). It’s very SNEAKY!

No thanks for making a right mess inside my body!

I mean, I look really good, I look really well, but you should see my INSIDES

No thanks for generating fibrosis throughout my mesentery and retroperitoneum!

I really didn’t know what to make of this issue at diagnosis, although I did know the aorta was pretty important!  Fortunately I had a surgeon who had operated on many NET patients and has seen this issue before.  After my first surgery, he described it as a “dense fibrotic retroperitoneal reaction encircling his aorta and cava (inferior vena cava (IVC))”. My surgeon was known for difficult and extreme surgery, so as part of the removal of my primary, he also spent 3 hours dissecting out the retroperitoneal fibrosis surrounding these important blood vessels and managed 270 degree clearance. The remnant still shows on CT scans. Some of the removed tissue was tested and found to be benign, showing only florid inflammation and fibrosis (thankfully).  That said, the abstract papers above has led me to believe that my retroperitoneal fibrosis is clinically significant.  In fact I have spent the last 3 months worrying about some of it growing into reach of important vessels and only just been given the all clear (for now). 

fibrosis an unsolved mystery

No thanks for screwing up some of my hormones

There are many hormones involved with Neuroendocrine Cancer which is unique in that different types can result in elevated levels of different hormones, often more than one is involved.  Serotonin has caused fibrosis in my retroperitoneal area and is currently threatening important vessels. I don’t really need that right now!


No thanks for the ongoing symptoms and side effects

I was showing symptoms of a Neuroendocrine Cancer syndrome known as Carcinoid Syndrome (currently) such as flushing and diarrhea and fatigue was probably there too, but these were thought to be something else or ignored (by me).  I don’t suffer too much nowadays other than side effects of the disease or the treatment I’ve had or receiving.  However, I know from speaking to many patients the effects of the various syndromes associated with Neuroendocrine Cancer can be pretty debilitating and oppressive to quality of life.

These syndromes can be so strange and so weird, they can be very difficult for patients, nurses and doctors to treat. They can be a real ‘witch’s brew’.

Surveillance and treatment for life SUCKS!

But I need constant surveillance, it’ll keep me alive.

No thanks for the weight loss

As if I needed it

No thanks for the hypothyroidism

Another pill for life. I have a left-sided thyroid lesion and my treatment also messes with my hormone levels.

No thanks for increasing my diabetes risk

No thanks for pushing me into pre-diabetes. My blood sugar is spiking, most likely due to treatment.

No thanks for making me retire early

I loved my job but not if it was going to kill me. I made my own decision  based on how I could survive in a financial sense. Made easier as I was only 8 years from retirement but I guess I’m one of the lucky ones despite the fact I took a big hit on the income going into my bank account.

The truth is that many people still need to work whilst struggling with side effects of the cancer and its treatment. Getting some form of financial assistance from the government is not a done deal.

Neuroendocrine Cancer is a very expensive disease to treat.

This is fast becoming a big issue regardless of country and regardless of healthcare system in place. However, in privately funded healthcare, it can be exacerbated by the level of insurance cover. Read more about financial toxicity for cancer patients which is a growing problem worldwide.

……….. and no thanks to anyone who says it’s a “good cancer

Pancreatic Cancer vs Neuroendocrine Tumors of the Pancreas

pancreatic vs neuroendocrine

I campaign hard for Neuroendocrine Cancer awareness including continually pointing out that a Neuroendocrine Cancer with a pancreatic primary is NOT Pancreatic Cancer as is often quoted in the press.  The two main reasons I take up these campaigns are as follows:

1.  They are totally different cancers despite an anatomical relationship.  Although they share some similar presentation, they have different signs, different treatments and vastly different prognostic outcomes.  What that means is that anyone who is looking for useful information on either needs to be very careful on interpretation, they could end up with very bad advice and in some situations, become more concerned than they should be (particularly with the prognostics).  See more below. 

2.  These two different cancer types have different awareness organisations, patient support groups and patient leaders/advocates. In most cases, vastly different awareness messages. Both of these organisations and advocates need all the help they can get, they need all the resources and funding they can get. 

Both Pancreatic Cancer and Neuroendocrine Cancer are diseases that need maximum publicity, both types of cancer have their own unique situations, thus why the awareness messages can be so vastly different.  It’s really important, therefore, that publicity surrounding famous patients be attributed to the correct cancer type in order that the advocate organisations and supporters can gain maximum benefit to forward their causes.  Unfortunately, thanks to doctors and media, this very often doesn’t work out in favour of Neuroendocrine Cancer due to the Human Anatomy of Neuroendocrine Cancer (this problem actually goes beyond the pancreas).

Where the press and doctors regularly get it wrong

Two famous people in particular, one in 2011 and the other this year, are regularly reported in the press as having died of Pancreatic Cancer.

Steve Jobs.  One of the most famous technical innovators of his time and creator of the most valuable company in the world. He had a Neuroendocrine Cancer with a pancreatic primary.  Read his story here.

steve-jobs-55-to-2011

Aretha Franklin. One of the most famous soul singers of her time.  She had a Neuroendocrine Cancer with a pancreatic primary. Read her story here.

rip-Aretha-Franklin-1

To summarise, Neuroendocrine Cancer is not a “type” of another cancer.

What are the differences? 

For me, one of the two main differences are the cell type. When people talk about Pancreatic Cancer, they really mean something known as “Pancreatic Adenocarcinoma”.  It starts in the exocrine cells, which produce enzymes to support digestion.  Neuroendocrine Tumors start in the endocrine cells which produce hormones.

For me, the other big difference is prognostics.  Unfortunately, it is statistically proven that most people with Pancreatic Adenocarcinoma will die, whereas most people with Neuroendocrine Tumors with a pancreatic primary will live.

For a more detailed comparison, see this excellent article from NET Research Foundation.

Pancreatic Cancer – Why I support their campaigns

Personally speaking, as a healthcare advocate online, I do support many cancer awareness campaigns, I think this is important to get similar help coming the other way (this frequently works for me).  However, I very much suspect, other than Neuroendocrine Cancer, my biggest support area online is for Pancreatic Cancer and other “less survivable” cancers.  I’m drawn by their excellent campaigns where they focus on key messages of prognostics for what is essentially a silent disease (in many ways the same issue with Neuroendocrine Cancer) and they make these more compelling by focusing on people rather than gimmicks. The prognostics can be upsetting reading as they are quite shocking figures which have not changed much in the past 40 years, a key sign that more must be done for this awful disease.   I frequently share this symptom graphic below because it might save a life and I ask that you do too.

pan can symptoms

Often though, the patients with a Neuroendocrine Cancer (pancreatic primary) are drawn to getting support from Pancreatic Cancer organisations. I suspect this is a combination of their own perceptions, their doctor’s language in describing their cancer type, and even something as simple as it was the first place they found help and support and they stick with that organisation.   You may also be interested in my article “I wish I had another cancer” – click here.

RonnyAllan.NET – Community Newsletter Covering October 2018


Summary for October 2018

NET News

Several headlines covering the past month:

1. The annual NANETS symposium took place last month and I constructed an article of several important outputs.  One day I might make it there, been to ENETS twice.  Would love to attend UKINETS but they don’t seem very ‘patient’ friendly.

2. I spoke alongside IPSEN Pharma SAS (Global HQ) at the annual Eye for Pharma Patient Summit. It was an honour and a privilege to stand in front of 200 people to tell my personal story plus my involvement in LivingWithNETs.com.  The audience was a mix of the Pharmaceutical industry, Healthcare industry and Patient Advocates from many different illnesses.  A fantastic and real awareness opportunity which is part of my promise to take NET awareness to new audiences rather than just share stuff between NET patients and advocates.

the best kind of story – a 2 legged one

3. I’m still reeling from winning the 2018 WEGO Blog Award and if you missed the live announcement, you can listen to the quite short video clip here.

Personal NET News

My NET. I still await the output from a meeting with my Oncologist and Surgeon to address the new issues identified my routine surveillance scan and a subsequent Ga68 PET/CT. Fortunately the issues are not classed as urgent at this stage. They have dismissed PRRT as an option at this stage (kept in reserve) and it looks like surgery might be on the cards.  You can read about my Ga68 PET/CT experience here and my fibrosis issues here.

Looking for Advice?

If you are reading this and you are currently undiagnosed but strongly suspect NETs – this article might help.

If you are diagnosed and looking for a NET Specialist and the sort of questions to ask – this article will help.

Neuroendocrine Cancer: A Witch’s Brew of Signs and Symptoms


cancer growth

One of the key awareness messages for Neuroendocrine Cancer is the hormonal syndromes that can often accompany the diagnosis for many people.  As it’s a difficult disease to diagnose, many people struggle with these syndromes for some time before formal diagnosis of Neuroendocrine Cancer. Some continue to struggle after.

The cancer can often be uncannily quiet, but the tumours can be ‘functional’ and over-secrete certain hormones to add or introduce symptoms which mimic many other diseases or conditions, such as Irritable Bowel Syndrome, Menopause, Heart disease and Asthma.   In addition to common symptoms of flushing and diarrhea, others include generally feeling weak, fatigued, pain, agitated, anxious, dizzy, nauseous, acid reflux, skin irritation, anaemic, lose weight, gain weight, low blood sugar, high blood sugar, heart palpitations, headaches, sweating, high blood pressure. Its main trick is to prevent you from being correctly diagnosed and it’s pretty good at it.  For those looking for a diagnosis, it can be very frightening.

One or more of the NET syndromes can be a weird concoction of strange, powerful or terrifying ingredients, designed to make you very ill; and doctors will be confused. 

Certain types of Neuroendocrine Cancer were once referred to by the out of date term of ‘Carcinoid‘ – now correctly referred to as a NET prefixed by its anatomical primary location. For the time being, the term Carcinoid Syndrome, associated with these types of NET persists; and is known to be capable of over secreting (amongst others) the vasoactive substance called serotonin. It is commonly thought that serotonin is the cause of the flushing, but this is only partially correct, the flushing also results from secretion of kallikrein, the enzyme that catalyzes a conversion to bradykinin, one of the most powerful vasodilators known.  Other components of the carcinoid syndrome are diarrhea, probably caused by the increased serotonin, which greatly increases peristalsis, leaving less time for fluid absorption, a pellagra-like syndrome, probably caused by diversion of large amounts of tryptophan from synthesis of the vitamin B3 (Niacin), which is needed for NAD production (oxidized form of B3). It also causes fibrotic lesions of the endocardium, particularly on the right side of the heart resulting in insufficiency of the tricuspid valve and, less frequently, the pulmonary valve and, uncommonly, bronchoconstriction. Other fibrosis spells include mesenteric and retroperitoneal desmoplasia which have the potential to dangerously obstruct important vessels and cause general discomfort at best.

 

serotonin

 

Carcinoid Syndrome is one of the most powerful and dangerous ‘witch’s brews’. 

The classic carcinoid syndrome includes flushing (80%), diarrhea (70%), abdominal pain (40%), valvular heart disease (40% to 45% but reduced to 20% since the introduction of somatostatin analogues), telangiectasia (25%), wheezing (15%), and pellagra-like skin lesions (5%). Carcinoid syndrome, first described in 1954 by Thorson and co-workers, has the following features: malignant neuroendocrine tumour of the small intestine, normally with metastases to the liver, sometimes with valvular disease of the right side of the heart (pulmonary stenosis and tricuspid insufficiency without septal defects), peripheral vasomotor symptoms, bronchial constriction, and an unusual type of cyanosis. One year later, Dr. William Bean gave the following colorful description of carcinoid syndrome:

“This witch’s brew of unlikely signs and symptoms, intriguing to the most fastidious connoisseur of clinical esoterica—the skin underwent rapid and extreme changes resembling in clinical miniature the fecal phantasmagoria of the aurora borealis.” 

Other witch’s brews include the group of NET syndromes associated with over-secretions of Insulin, Glucagon, Gastrin, Vasoactive Intestinal Peptide (VIP), Pancreatic Polypeptide (PP) and Somatostatin.  Read more about these and other syndromes here.

NET Syndromes

One of the most scary witch’s brews is the group of symptoms associated with one of the most uncommon types of NET, the catecholamine and metanephrine (adrenaline and noradrenaline) secreting tumours known as Pheochromocytoma and Paraganglioma. These tumours are likely to cause a barrage of symptoms such as High blood pressure, Heavy sweating, Headache, Rapid heartbeat (tachycardia), Tremors, Paleness in the face (pallor) and Shortness of breath (dyspnea).

All of the above is a diagnostic nightmare for those who have the symptoms and remain undiagnosed – no fun for the doctors either – this why we need so much more awareness and education – it’s one of the key aims of all my social media sites.  Another aim of my sites is to support those who are diagnosed as these symptoms can continue following diagnosis and treatment. Many NET patients need constant surveillance and follow-up, many for life.

This is a very spooky disease, it will slowly grow without you knowing, it will mess with your body and mind, and if left alone to plot its devious and destructive course, it will kill.  Some are faster growing but they have the same traits – they just kill faster.  Share this post and potentially save a life.

How to Talk to a Cancer Patient Without Being a Complete Twit

I enjoyed reading “8 rules on how to talk to a cancer patient” because I think much of it is written with ‘tongue in cheek’.  Great title!

In UK we might even spell the word ‘twit’ slightly differently (UK people will get it!). Some of the rules are directed at doctors and I’m sure some doctors will laugh (if you’re a doctor and you didn’t laugh, sorry). I think one or two are a bit harsh and could potentially backfire and at least one I partly disagree with.  Personally I try to balance my reactions to not come over as a ‘pity party’ and something which is genuinely offensive or upsetting to me as a cancer patient.  I appreciate understanding and empathy, perhaps sympathy, but I certainly don’t want pity.

I’ve added rule number 9 which is a true story I picked up in my own community which I found absolutely unacceptable and I certainly did not laugh.  Thanks to ‘Patient A’ for the quote.

You may also enjoy this article which contains 16 ‘red flags’ that might mean it’s time to find a new doctor.  Easier in some countries than others and I suspect we have all encountered at least one of them.  I don’t think we should be changing doctors too often and we shouldn’t be changing just because of one of these ‘red flags’ (although the example above is pretty offensive).

Another good one is an actor based video which discusses about the things people sometimes say (often clumsily) to patients that often don’t hit the right chord – check out my article “Things not to say to a someone with cancer“.

And of course we all look so well as Neuroendocrine Cancer patients – but you should see our insides.

Living with Cancer – Worrier or Warrior?


WORRIER OR WARRIOR (2)

If you only believe what you see on social media, you would probably classify cancer patients into two main groups, warriors or worriers.  I guess people have, or adopt, these traits from their cancer experience but I suspect many people are simply ‘wired’ that way.  I also believe there are many people who have a bit of both, perhaps slanting to mostly warrior or worrier, I mean who doesn’t worry about a single thing?  However, the extent of worrying can often have a negative effect on quality of life. You’re not going to stop worrying by simply reading this article but if you read no further, at least check out the lead graphic, it might help putting things into perspective.

Warriors

I used to do that for a living so I guess I’m an automatic fit, right? Believe it or not, professional ‘warriors’ also worry about stuff but they don’t like showing it (one of the reasons there are serious PTSD issues happening currently).

Despite the protests at the use of ‘war’ metaphors, many cancer patients do see themselves as ‘warriors’.  People probably label me as one but …… spoiler alert, behind my positive exuding exterior, there’s a man worried about a problem which might decrease quality of life and also a man worried about potential surgery most likely needed to correct the issue. We all worry but it’s the way we handle stress that is important.  Not talking about it is never a good option.

Poker Face or Cancer Card

I also think ‘Warriors’ can sometimes be complacent and for a cancer patient, this can be detrimental to their health.  In a previous life, nothing was going to stop me getting on with life, nothing was going to stop me going to work, nothing was going to stop me completing my mission.  One day, some of my co-workers complained about my constant sneezing, coughing and sniffing. I told them the only way I was leaving the building would be on a stretcher having lost consciousness or in a body bag.   I said it whilst I continued typing up a report which was my mission for that day.  I said it without any hint of joviality in order they knew that I was deadly serious.  Little did I know that my ‘poker face’ was just about to become seriously deadly.

We’ve all read the blogs and memes on Facebook…. ‘kicking cancer’s ass‘, etc etc. There’s even twitter handles, Facebook sites, blog names all with the word ‘warrior’ in the title. Nothing wrong with that, nothing wrong with having a positive attitude. The only thing potentially wrong with that, is becoming too complacent about the danger of cancer. Cancer will kill you whether you are a ‘warrior’ or a ‘worrier’.

Worriers

I come into contact with a lot of Neuroendocrine Cancer patients, either from a thread in my group, my blog site or my Facebook site(s).
