Carcinoid vs Neuroendocrine

OPINION - There's a constant debate regarding the validity of the term 'Carcinoid'. I've posted about this a few times and as far as I know, the debate has been raging for some years. This post was originally generated in April 2015 (and hasn't changed that much!).EDIT MARCH 2024. There is now a consolidated Endocrine/Neuroendoceine Tumour classification system (Blue Book). Still in print but you can see a summary of changes by clicking here. This change should provide some leverage to Neuroendocrine committees particularly about what things should be called. EDIT MARCH 2022. The latest classification system for Lung Neuroendocrine Neoplasms (NEN) confirms the word "carcinoid" is now a choice when you look at the document index. However, the WHO Lung Committee bottled it by leaving it in, and we now need to…

Neuroendocrine Cancer – Horrible Hormones

Patient Advocacy

Updated and reviewed 20th March 2024 Hormonal imbalances are quite common in many conditions including day to day stuff. With Neuroendocrine Cancer, it can be a real challenge both at diagnostic and maintenance phases. In addition to the cancer angle, there's some strange stuff going on, inexplicable, frightening for the patient, an unwanted ingredient causing chaos! Until I was diagnosed with metastatic Neuroendocrine Cancer, I didn't have a clue about hormones - it's one of those things you just take for granted. However, hormones are vital to human health (male and female) and it's only when things go wrong you suddenly appreciate how important they are. Hormones are involved in many conditions, not just an issue with Neuroendocrine Tumours (NETs) but the presence of over-secreting hormones (often called peptides throughout)…

Neuroendocrine Cancer: If your doctors don’t suspect something, they won’t detect anything!

Awareness, Patient Advocacy

One of the most discussed and debated Cancer issues is late diagnosis. Cyberspace is full of disturbing stories and many different cancers are involved. Some cancers are notoriously difficult to diagnose, meaning that awareness and education needs to extend from the general population to healthcare professionals at all levels. The latter is a challenge as first-line physicians battle to deal with thousands of different conditions, many of which have similar presentations. Neuroendocrine Neoplasms have a record of being difficult to diagnose which often leads to late diagnosis. Moreover, due to their often-silent nature, a late diagnosis is often a default scenario as no intervention was possible without a symptomatic patient.Neuroendocrine Neoplasms - Under-diagnosed or Under-reported?Like many other Cancers, Neuroendocrine Neoplasms (NEN) is one of a number of 'difficult to diagnose'…

Neuroendocrine Cancer – Clinical Esoterica

Awareness

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.Neuroendocrine Cancer can often be uncannily quiet, but the tumours can be 'functional' and over-secrete certain hormones to add or introduce symptoms that 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, weight loss, weight gain, low blood sugar, high blood sugar, heart palpitations, headaches, sweating, high blood pressure.…

Childhood Cancer Awareness Month – Neuroendocrine Cancer (featuring Elizabeth)

General

September is Childhood Cancer Awareness Month! The newspapers and social media will no doubt be featuring many childhood cancer articles. You may not see one about NET though. I personally cannot begin to imagine what it must be like to be a parent who has a child with cancer. I would just hope my child would be placed into the care and safe custody of experienced medical teams and would be able to get access to the best treatments available. I don't know that much about Childhood cancers, but I do know that over half of childhood cancers are either Acute Leukaemias or Brain Cancer, both of which are frequently in the news. It always breaks my heart when I read stories of children with cancer. I do know a…

Neuroendocrine Cancer – normally slow but don’t be fooled!

Awareness

An awareness post from Ronny Allan. There are a lot of scary diseases in this world but some of them are particularly sneaky. One such sneaky disease is the lesser-known type of cancer that infiltrated my body - Neuroendocrine Cancer. Not only is it scary and sneaky, but it's also cunning, devious, misleading, and double-crossing. It likes nothing better than to play tricks on you. Don't be fooled, it's the great pretender. It will grow in your body without you knowing. It finds places to hide, mainly the small intestine, appendix, lungs, stomach, pancreas, rectum, and a host of other places. It can be fiendishly small to avoid being seen. Once it's established in the primary location (....or locations), it will try to break out via your blood and lymphatic…

Belzutifan for the Treatment of Advanced Pheochromocytoma/Paraganglioma (PPGL), Pancreatic Neuroendocrine Tumor (pNET), or Von Hippel-Lindau (VHL) Disease-Associated Tumors

Clinical Trials and Research, Treatment

What is von Hippel-Lindau disease (VHL)?Von Hippel-Lindau disease (VHL) is an autosomal dominant disease that can predispose individuals to multiple neoplasms. Germline pathogenic variants in the VHL gene predispose individuals to specific types of benign tumors, malignant tumors, and cysts in many organ systems. These include central nervous system hemangioblastomas; retinal hemangioblastomas; clear cell renal cell carcinomas and renal cysts; pheochromocytomas, cysts, cystadenomas, and neuroendocrine tumors of the pancreas; endolymphatic sac tumors; and cystadenomas of the epididymis. What is Belzutifan (Welireg)?It is an oral hypoxia-inducible factor-2 alpha (HIF-2α) inhibitor. As an inhibitor of HIF-2α, belzutifan reduces transcription and expression of HIF-2α target genes associated with cellular proliferation, angiogenesis and tumor growth.On August 13 2021, FDA approved belzutifan (Welireg) to treat adults who have several tumors associated with VHL. Specifically, the drug is approved to treat VHL-associated renal cell carcinoma (a type of kidney…

Neuroendocrine Neoplasms (NEN) – genetic related syndromes

Awareness, Patient Advocacy

Cancer is a genetic disorder. It happens when genes that manage cell activity mutate and create abnormal cells that divide and multiply, eventually disrupting how your body works. Medical researchers estimate 5% to 12% of all cancers are caused by inherited genetic mutations that you can’t control. More frequently, cancer happens as an acquired genetic mutation. Acquired genetic mutations happen over the course of your life. This is a very general description of the close relationships between genetics and cancer but I wanted to focus below on hereditary syndromes and genetic disorders related to Neuroendocrine Neoplasms. Definitions - the differences between Hereditary vs Familial vs Genetic DisordersI wanted to start with these definitions because people may unintentionally use these three terms interchangeably which is sometimes not the correct use of the information…

The Hidden Pheochromocytoma

Awareness, Patient Advocacy

I've written a few times about Pheochromocytomas and Paragangliomas, allegedly rare types of Neuroendocrine Tumour (NET). I've also written about various hidden diagnoses of NET cases where they are eventually found in living patients having been 'hidden' within other diseases, i.e. misclassified in cancer registries or even not classified as cancer at all. If you read any medical site (including hospitals which treat Pheochromocytoma) you will note statements along the lines of "mostly benign" - so it's possible the incidence rate is vastly understated on this factor alone.The other interesting data I found is that many are not discovered until autopsy. Perhaps some people were asymptomatic or maybe they just stoically put up with their symptoms. Perhaps their symptoms were put down to routine illness such as hypertension, maybe imaging…

Neuroendocrine Cancer – no sweat!

Living with Neuroendocrine Cancer

I see so many questions and comments in my private group about sweating, in particular, 'night sweats' and it's prompted me to dig deeper, thus this article.When I look at a dozen decent sources of medical info, they all seem to bring up several common causes appearing on the different lists on each website I look at. I do see (so-called) carcinoid syndrome come up infrequently and perhaps the authors are lumping that in with hot flashes/flushing etc. But on authoritative NET sites (i.e. written by the NET scientific community), I do not see 'sweating' come up in the list of known symptoms directly attributed to any of the syndromes except for the group of catecholamine secreting tumours known as Pheochromocytoma and ParagangliomaI decided to extend it to diet because…

Targeted Therapy for Neuroendocrine Cancer – Sunitinib (Sutent)

Clinical Trials and Research, Treatment

Click here to see the A to Z of Neuroendocrine Cancer What is Sunitinib (Sutent)? Manufactured by Pfizer, this is a targeted biological therapy or more accurately, a multitargeted tyrosine kinase inhibitor (TKI). You may also see it described as an anti-angiogenic agent on the basis that these tumor types are highly vascularized and show high expression of something called vascular endothelial growth factor (VEGF), a key driver of angiogenesis in neuroendocrine tumors. Because NETs are generally hypervascularized tumors, treatment with antiangiogenic drugs seems a rational approach. A complex process but in the simplest of terms, sunitinib blocks a particular enzyme and keeps tumors from making their own blood vessels, which are needed to deliver oxygen and other nutrients to help them survive and grow. In clinical trials, SUTENT was…

Clinical Trial: Lu-177 DOTATOC (PRRT) in adult subjects with Somatostatin receptor (SSTR) positive Pulmonary, Pheochromocytoma, Paraganglioma, Unknown primary, and Thymic Neuroendocrine Tumors

Clinical Trials and Research

Excellent news for those who don't have Gastroenteropancreatic NETs (GEP-NETs). A trial of PRRT is being set-up for the less common types of NET including those with an unknown primary. Using the DOTATOC radionuclide rather than the Lutathera model of using DOTATATE, this trial will cater for Pulmonary, Pheochromoctyoma, Paraganlioma, Unknown Primary and Thymic Neuroendocrine Tumours.Excel Diagnostics and Nuclear Oncology Center (EDNOC) announced today that its physician sponsored Investigational New Drug (IND) application to evaluate safety and efficacy of Lu-177 DOTATOC in adult subjects with Somatostatin receptor (SSTR) expressing Pulmonary, Pheochromocytoma, Paraganglioma, Unknown primary, and Thymic Neuroendocrine Tumors (PUT-NET), has received approval to proceed by USA Food and Drug Administration (FDA) and also charge authorization has been granted (IND#143631, NCT04276597).

“Please find something wrong with me”

Awareness, Patient Advocacy

I’m contacted almost daily by the ‘undiagnosed’ who suspect they have Neuroendocrine Cancer, often because they appear to be displaying the symptoms of one of the associated syndromes and my large internet footprint leads them to me. These are some of my most difficult questions. I’m always very wary of initially agreeing with their assumptions and logic, instead opting for straightforward detective work based on my knowledge of the different types of Neuroendocrine Cancer, knowledge of the best scans, the best tumour and hormone markers. And I always warn them that statistically, they are more likely to have a common condition than the less common Neuroendocrine Cancer. When I first chat with the ‘undiagnosed’, I find many of them are fairly knowledgeable about Neuroendocrine Cancer and other health conditions, again…

Clinical Trials – PEN-221 for Neuroendocrine Cancer

Clinical Trials and Research

What is PEN-221?Tarveda Therapeutics is discovering and developing a new class of potent and selective precision oncology medicines for the treatment of patients with various solid tumor malignancies. Their strategy includes developing their own proprietary Pentarin miniature conjugates to enhance the effectiveness of promising anti-cancer payloads that have struggled without their selective targeting to solid tumors. These medicines are known as 'Pentarins'. PEN-221 is the lead candidate 'Pentarin' aimed at Neuroendocrine Cancer - PEN-221.Somatostatin receptor 2 (SSTR2) is frequently overexpressed on several types of solid tumors, including neuroendocrine tumors and small-cell lung cancer. Peptide agonists of SSTR2 are rapidly internalized upon binding to the receptor and linking a toxic payload to an SSTR2 agonist is a potential method to kill SSTR2-expressing tumor cells. PEN-221 is a conjugate consisting of microtubule-targeting…

Clinical Trials – ONC201 for Neuroendocrine Cancer (including Pheo/Para)

Clinical Trials and Research

What is ONC201?A company called Oncoceutics is developing a novel class of safe and effective cancer therapies called imipridones. Imipridones have a unique three-ring core structure and selectively target G protein-coupled receptors (GPCRs), the largest class of membrane receptors and a common target of approved drugs that are underexploited in oncology. Despite being historically uncommon as targets in oncology, GPCRs control an array of critical prosurvival and stress signaling pathways that are often dysregulated in human cancer to favor cancer cell survival and propagation.The ability of imipridones to target GPCRs with a high degree of selectivity represents a novel opportunity in oncology that generates remarkably safe and effective therapeutics. ONC201, the founding member of this novel class of therapies, is an orally active, safe, and selective antagonist of the GPCR…

Weight – the NET Effect

Firstly, let me say that I have no intention of advising you how to lose or gain weight! Rather, I'd like to discuss what factors might be involved and why people with NETs might lose or gain weight either at diagnosis or after treatment. Clearly, I can talk freely about my own experience and associated weight issues. If nothing else, it might help some in thinking about what is causing their own weight issues.I once wrote a patient story for an organisation and the headline was "Did you mean to lose weight". Those were actually the words a nurse said to me after I nonchalantly told her I thought I'd lost some weight (....about half a stone). I answered the question with "no" and this response triggered a sequence of…

Genetics and Neuroendocrine Tumors

Awareness, Living with Neuroendocrine Cancer, Survivorship

Hereditary genetics.....where to focus In recent years, it has become increasingly apparent that a number of Neuroendocrine tumours arise as a result of germline genetic mutations and are inherited in an autosomal dominant pattern. The number of genes implicated is increasing and I cannot guarantee this post will contain all of them. Apparently, 5-10% of NETs are estimated to have a hereditary background. Hereditary syndromes associated with these include Multiple Endocrine Neoplasia (MEN), Von Hippel Lindau (VHL), Neurofibromatosis Type 1 (NF1), Tuberous Sclerosis (TS) and others. People who have a genetic condition may present with the tumors (perhaps along with an associated functional hormone syndrome) and so the genetic condition if there is one, may not be known at this point.

Ever wonder what caused your Neuroendocrine Cancer?

Patient Advocacy

OPINION. When you're diagnosed, you go through a whole host of emotions. It's not just the initial shock, the disbelief, the anxiety and morbid worry produced by the words "you have cancer", it's other stuff such as anger and denial. With the latter, the denial normally wears off as you finally accept the predicament. In hindsight, the anger is interesting because there can be a mixture of thoughts including "why me", "what could I have done to head this off"; and would you believe I was even angry that my diagnosis was going to affect my performance at work and even my personal credibility. We all react differently but in general terms our experiences can be categorised into 3 main areas: initial reaction, distress and then adjustment. Initially, I was frustrated…

The Invisible NET Patient Population

Awareness

OPINIONI found some of the quotes from the recent NET SEER Database study (Dasari et al) very interesting. The National Cancer Institute’s Surveillance, Epidemiology, and End Results (SEER) Program is a comprehensive source of population-based information initiated in 1973 that is updated annually. Although the study is US-based, it represents the largest study of Neuroendocrine Neoplasms (NENs) ever recorded and is therefore a good guide to what might be found beyond USA. Almost 7 times the rate recorded in the 1970s. If you want to understand the factors behind this massive increase, I covered this extensively in my post "Neuroendocrine Neoplasms – not as rare as you think". However, most things I read indicate the figures were understated (words used by several NET specialists). Despite this date now being 8 years…

Immunotherapy: Studies with Neuroendocrine Neoplasms

However, I also wanted to break it down and perhaps see if I can pick up the what, when, why, where and how in regard to Neuroendocrine Cancer. It's difficult, not least because the picture is not clear and there is no general roadmap printed, let alone one for Neuroendocrine disease. Immunotherapy for NETs was discussed at ENETS 2017 in Barcelona. The presentation that sticks out was one given by Dr Matthew Kulke, a well-known NET Specialist in Boston. My reaction to the presentation was one of 'expectation management' and caution i.e. it's too soon to know if we will get any success and when we will get it. He also hinted that it's more likely that any success will first be…

All you need to know about Peptide Receptor Radionuclide Therapy (PRRT)

Clinical Trials and Research, Treatment

Updated 23rd April 2024 Updated 23rd April 2024 Short PRRT PrimerWhat is Peptide Receptor Radionuclide Therapy (PRRT)?What is PRRT? PRRT stands for Peptide Receptor Radionuclide Therapy, an FDA-approved therapy used for systemic treatment of neuroendocrine tumors.Peptide refers to the small molecule for this therapy. The Peptide used (e.g. DOTATATE or DOTATOC or DOTANOC) is very similar to Somatostatin, a hormone which binds to receptors found on neuroendocrine tumors.Receptor refers to a specific target on neuroendocrine tumor cells that the peptide attaches to. After the peptide joins with a Receptor, it becomes attached and enters the targeted tumor cell.Radionuclide refers to radioactive atom that is attached to the peptide. As the peptide enters the cell, it brings the Radionuclide into the tumor cell. The radionuclide (e.g. lutetium-177), then decays and emits radiation within the tumor cell.Therapy refers to the idea that…

[caption id="attachment_14426" width="1200"] Courtesy of Pashtoon Kasi MD on Twitter https://twitter.com/pashtoonkasi/status/1078675398601396224[/caption] Theranostics is a joining of the words therapeutics and diagnostics. You may also see it conveyed as 'Theragnostics' and these terms are interchangeable. The basic aim of theranotistics is to find and then destroy the 'bad guys'. With Neuroendocrine Cancer, finding the tumours (the bad guys) can often be a challenge - they can be small and/or difficult to find - they are sometimes expert at camouflage. Moreover, once found, they can then be difficult to treat (destroy), as they can often prove resistant to conventional cancer drugs and many are inoperable due to sheer quantity, spread and positioning. When they are found and identified, it's also really helpful to know from the intelligence gathered, how successful the destroy…

Neuroendocrine Tumours: a spotlight on Pheochromocytoma and Paraganglioma

A spotlight on NENs - Types, Awareness, Patient Advocacy, Spotlight on NENs - Types Series

Updated 19th November 2023I spend a lot of time talking about the most common forms of Neuroendocrine Tumours (NETs), but what about the less well-known types? As part of my commitment to all types of NETs, I'd like to shine a light on two less common tumour types known as Pheochromocytomas and Paragangliomas - with an incidence rate of approximately 8 per million per year. They are normally grouped together, and the definitions below will confirm why. If you think it's difficult to diagnose a mainstream NET, this particular sub-type is a real challenge.So, let's get definitions out of the way:Pheochromocytomas (Pheo for short)Pheochromocytomas are tumours of the adrenal gland that produce excess adrenaline. They arise from the central portion of the adrenal gland, which is called the adrenal medulla…

Neuroendocrine – don’t let it be a Crisis

And the study also noted that medication to treat complications was still required. I don't believe we should immediately dismiss this conclusion as one of the authors is a 'big hitter' NET Specialist surgeon (Dr Rodney Pommier) whose job is to keep patients safe on the operating table.

Neuroendocrine Cancer – If you can see it, you can detect it!

Living with Neuroendocrine Cancer, Survivorship

Content in my review queue (line). BackgroundScanning is a key diagnostic support and surveillance tool for any cancer. Even though you have elevated bloods or urine (....or not), a picture of your insides is really like a thousand words.... and each picture has a story behind it. Scanning can be a game changer in the hunt for tumours and although scans do not normally confirm the cancer type and grade, they certainly help with that piece of detective work and are key in the staging of the cancer.When I read stories of people in a difficult diagnosis, I always find myself saying 'a scan might resolve this' and I always suggest people should try to get one. Even in the case of a story about late diagnosis or a misdiagnosis, I find myself thinking 'if…

BackgroundSome people on hear the terms "tumour markers" and "hormone levels" when they are diagnosed with Neuroendocrine Cancer. Most of them will have had a form of medical testing at some point in their life, i.e. the sampling and testing of blood, urine, saliva, stool or body tissue. In a nutshell, the medical staff are just measuring the content of a 'substance' and then taking a view whether this is normal or not based on pre-determined ranges. These tests are normally done as a physician's reaction to symptom presentation or maintenance/surveillance of an existing diagnosed condition. Sometimes, abnormal results will lead to more specialist tests.In cancer, these tests are frequently called 'markers'. Most tumour markers are made by normal cells as well as by cancer cells; however, they are produced at…

The 5 E’s (of Carcinoid Syndrome)

Awareness, Diet and Nutrition, Living with Neuroendocrine Cancer, Patient Advocacy, Survivorship, Treatment

Since my diagnosis, I seem to have been in a perpetual learning phase! What not to do, what not to eat, what not to read! However, early on in my experience, I came across a list of 'E' words (5 of them) which is a handy reminder for Carcinoid Syndrome patients, particularly those whose symptoms are not under control. When I say "carcinoid syndrome" in this article, I only mean the syndrome that is caused by what was once called "Carcinoid Tumors", i.e. predominately serotonin secreting types which mainly metastatic cases where the well differentiated tumours are found in the small intestine, but much less commonly in appendiceal, very rarely in rectal (rarely even at stage IV), lung (more atypical and around 10%), and one or two other significantly less…

A spotlight on Multiple Endocrine Neoplasia (MEN)

Awareness, Living with Neuroendocrine Cancer

This is an overview, if you require detail, try my more comprehensive post by clicking here or on the picture[caption id="attachment_38157" align="aligncenter" width="640"] Click on the picture to read more[/caption]OverviewWe all know that Neuroendocrine Tumours (NETs) and their syndromes are complex but there is even more complexity to be found in a group of related disorders known as Multiple Endocrine Neoplasia (MEN). I recommend all NET patients should try to understand the basics of MEN and vice versa, particularly as both conditions seem to come with a plethora of endocrine-related effects.MEN patients will normally have a tumour in at least two endocrine glands - thus the terms 'Multiple' and 'Endocrine' (tumours can also develop in other organs and tissues). Neoplasia is just another name for tumour and these can be non-cancerous (benign) or…

I bet my flush beats yours?

Awareness, Living with Neuroendocrine Cancer, Patient Advocacy, Treatment

Updated Feb 2024. BackgroundNeuroendocrine Tumours (NETs) can sometimes present with one or more vague symptoms which occasionally results in a lengthy diagnostic phase for some. Sure, there can be issues with doctor experience and knowledge that can add to the problem. However, some people do present with multiple vague and confusing symptoms and some people have comorbidities that have similar symptoms. Textbook diagnostics just don't make sense, sometimes even when the doctor suspects a NET i.e. classic symptoms of 'something' but with negative markers for NETs. Clearly, those are extreme cases and just like other complex diseases, many diagnoses of NET can be extremely challenging. Even for an experienced doctor, it can be a difficult jigsaw!Most types of NET can have associated 'syndrome' i.e. the tumours are 'functional' and this is normally (but…

PRRT and the NHS England Cancer Drugs Fund (now archived information)

Treatment

[caption id="attachment_3922" align="aligncenter" width="425"] cost cutting vs life cutting?[/caption] Please note this post is now historic information - PRRT (Lutathera) was eventually approved for use in UK. See the following post for the very latest on PRRT worldwide - CLICK HERE I was extremely disappointed to learn of the decision to remove PRRT (Lutetium or Yttrium) from the Cancer Drugs Fund (CDF). You can read the detail of the decision here: CDF Statement. PRRT has regularly been described by NET specialists and patients as the "magic bullet" due to its potential to shrink or kill tumours. This is the second Neuroendocrine Cancer treatment to be withdrawn this year, after the earlier decision on Everolimus (Afinitor) in April . In fact, the recent cuts to the CDF were described in the…

The Syndromes of Neuroendocrine Cancer – Early Signs of a Late Diagnosis

Awareness

The Syndromes of Neuroendocrine Cancer - Early Signs of a Late DiagnosisOne of the curious things about Neuroendocrine Cancer (NETs elsewhere in the text on the basis that a hormonal syndrome is extremely rare in Neuroendocrine Carcinoma (NEC)) is that it can very often exhibit one or more vague symptoms collectively known as a 'syndrome'. Syndrome is an apt word to describe these complications as the most general meaning in medical terms is a group of symptoms that together are characteristic of a specific disorder or disease". Having a syndrome can often be the difference between having a 'functional' condition or a non-functional' condition - see more below.This frequently makes NET very difficult to diagnose quickly. It's a very devious disease.Functional / Non-FunctionalThese tumours and associated syndromes are treatable for…
