Understanding Differentiation, Ki‑67, Mitotic Count, Hotspots, Pathology Workflow, and Primary–Metastasis Heterogeneity in Neuroendocrine Neoplasms (NENs)

Understanding Differentiation, Ki‑67, Mitotic Count, Hotspots, Pathology Workflow, and Primary–Metastasis Heterogeneity in Neuroendocrine Neoplasms (NENs)

Patient Advocacy, Treatment, , , , , ,
Before you read this… This article discusses pathology concepts such as Ki-67, grading, heterogeneity, and biopsy findings in neuroendocrine tumours (NETs). It is provided for educational purposes only and does not interpret any individual pathology report or scan result. Ki-67 values, tumour grade, and sampling limitations can vary between different biopsies and over time. Their meaning depends on the full clinical context, including imaging, symptoms, and multidisciplinary review. Only your own specialist team can explain what your specific Ki-67, grade, or pathology findings mean for you. No treatment decisions should be made based on this article alone. Neuroendocrine Neoplasms (NENs)…

Why liver transplant is back in the NET conversation

Why liver transplant is back in the NET conversation

Patient Advocacy, Treatment, ,
Before you read this… This article is provided to support understanding of a complex and evolving topic. It explains how liver transplant is being explored in a very small number of NET patients, but it is not suggesting that this treatment is suitable for you or anyone else. Every NET case is unique. Only your own specialist team can assess your individual situation and advise on the options that may be appropriate for you. 1. Big picture: why liver transplant (LT) is back in the NET conversation Rationale: For a very small, highly selected subset of patients with unresectable liver-only…

This too shall pass

This too shall pass

Inspiration, Patient Advocacy
If you've heard that phrase before, you're not alone.  The phrase is rooted in older Persian and Buddhist teachings, and widely accepted as a testament to the impermanence of all things.  Many famous people have used this phrase including Abraham Lincoln, Tom Hanks, Robert De Niro and King Solomon.  I've also seen various cancer bloggers use it many times.  I've used it few times too, mainly for quick Facebook updates. This has been both an exciting year but also so far, a 'this too shall pass' moment in March. Exciting because I was on the holiday of a lifetime for…

HRT and Neuroendocrine Tumours (NETs): What Patients Need to Know

HRT and Neuroendocrine Tumours (NETs): What Patients Need to Know

Patient Advocacy, , , , , , , , ,
Before you read this… This article discusses hormone replacement therapy (HRT) in the context of general health, menopause, and neuroendocrine tumours (NETs). It is provided for educational purposes only and does not recommend starting, stopping, or changing any form of HRT. The suitability of HRT depends on many individual factors, including tumour type, grade, hormone sensitivity, medical history, and personal risk–benefit considerations. These vary widely between people with NETs. Only your own specialist team can advise on whether HRT is appropriate for you. No treatment decisions should be made based on this article alone.   Hormones and cancer often get…

Blood Clot risks in Neuroendocrine Neoplasms (NENs)

Blood Clot risks in Neuroendocrine Neoplasms (NENs)

Patient Advocacy, Treatment, , , , , ,
I have a personal interest in this subject because I had pulmonary emboli (PE) diagnosed in January 2011 around 6 weeks after I had major surgery.  I got a phone call from the hospital to go down that day and meet with a nurse who would teach me to self inject 'Clexane'(Enoxaparin) and then take away a stock which was to be issued in future via the normal prescription system. The PE soon cleared up shortly after being found but my Oncologist advised me to keep taking blood thinners to reduce risk. After many years of these daily injections, I…

Neuroendocrine Tumours (NETs) – Vitamin D (Cholecalciferol / Ergocalciferol)

Neuroendocrine Tumours (NETs) – Vitamin D (Cholecalciferol / Ergocalciferol)

Diet and Nutrition, Patient Advocacy, ,
Vitamin D is a fat-soluble vitamin (along with A, E and K).  Fat-soluble vitamins are absorbed with the other fats from the food you eat.  Fat-soluble vitamins can stay in your body for a while. When they’re stored in your body’s fat, they can be stored for up to 6 months until your body needs them.  Vitamin D doesn’t occur naturally in most foods. Instead, your body produces vitamin D when sunlight directly hits your skin (not through a window).   Vitamin D deficiency is demonstrably more common in people with neuroendocrine tumours (NETs) — but that does not automatically mean your…

Cancer: Words are important but so is context

Cancer: Words are important but so is context

Inspiration, Patient Advocacy,
Words are very important to cancer patients, some people hang their hats on them and put their feet up, and some people google them until they are tied in a knot, still fraught with worry.  Why can’t doctors just tell me in layman’s language?  Easy answer ……. because it is not an exact science. Doctors are not robots (…… yet!), they are human beings just like us.  Doctors have different views and they can have different interpretations of long standing terms ingrained in the annals of medicine.  Some doctors have better patient communication.  They don’t have crystal balls, but they…

Neuroendocrine Tumours (NET) – Vitamin B12 (Cobalamin)

Neuroendocrine Tumours (NET) – Vitamin B12 (Cobalamin)

Diet and Nutrition, Patient Advocacy, , , , , , , , , , , , , , ,
Vitamin B12 is a water-soluble vitamin.  Unlike fat-soluble vitamins, they are not stored in your body long term. They enter your bloodstream, and anything your body doesn’t need is eliminated through your urine.  Since water-soluble vitamins don’t last long in your body, they need to be replenished frequently.  You can find B vitamins almost everywhere. If you have a deficiency in a certain B vitamin, you may need to increase your intake of certain foods. Foods high in B vitamins include whole grains, seafood, poultry, eggs, dairy, leafy greens, beans. If you’re eating a well-rounded diet, you may not need any supplements.…

When I was a young lad, I didn't seem to have a fear of heights, not that I got many chances to test it but a couple of things springs to mind.  As a 'feral youth' I once climbed to the top of a factory building without fear.  I won't divulge any further detail, just setting the scene.....   In the military, I was in the rock climbing club.  Prior to that I was moved from 'boxing' as it was considered too dangerous for me (military logic!).  Following that, I did take part in annual adventure training, participating a few times…

Zanzalintinib Versus Everolimus in Participants With Locally Advanced or Metastatic Neuroendocrine Tumors (STELLAR-311)

Zanzalintinib Versus Everolimus in Participants With Locally Advanced or Metastatic Neuroendocrine Tumors (STELLAR-311)

Clinical Trials and Research,
A Phase 2/3, Multicenter, Randomized Open-Label Study of Zanzalintinib vs Everolimus in Participants With Previously Treated, Unresectable, Locally Advanced or Metastatic Neuroendocrine Tumors.  The primary purpose of this study is to assess the effectiveness of zanzalintinib compared to everolimus in participants with previously treated, unresectable, locally advanced or metastatic neuroendocrine tumors. Zanzalintinib (XL092) is an investigational, oral, multi-targeted tyrosine kinase inhibitor (TKI) being developed by Exelixis for various advanced cancers, blocking pathways like VEGFR, MET, and TAM kinases (AXL, MER, TYRO3) involved in tumor growth, spread, and resistance to therapy. Everolimus is already known in NET circles. This study has 25…

Next Generation Total-Body PET/CT: Challenges and Opportunities

Clinical Trials and Research, Patient Advocacy, , , ,
Long-axial field-of-view (LAFOV) systems have changed the field of molecular imaging. Since their introduction, many PET centres have installed these next-generation digital systems to provide more detailed imaging and acquire PET images in a single bed position. Indeed, vertex to thigh imaging for oncological indications can be obtained in most of the population with the currently available LAFOV systems. Moreover, Total Body (TB) PET, a subtype of LAFOV, enables imaging the entire patient—from vertex through the toes—with one bed-position for most of the population. This review aims to identify possible challenges and opportunities for PET-centres working with TB and LAFOV…

Summary of 2025 from Ronny  It was a good year for my advocacy work but a difficult year personally which had some impact on my advocacy work.  I had to spend quite a bit of time looking after my brother's affairs when he was diagnosed with dementia and is now living in residential care. That took a lot of  my free time away, not that I resent it, it's just one of those things you just have to do, despite the stress it entails.  I also have a glitch on my website affecting iPhones which I'm slowly working through.   …

A thankful statement My Facebook memories today are full of Christmas activities including my first Christmas following diagnosis of advanced Neuroendocrine Cancer.  I had been out of hospital for only 4 weeks following major surgery in 2010.

Neuroendocrine Cancer: I hadn’t heard of it until I was diagnosed with it

Awareness, Patient Advocacy,
My diagnosis came with many strange words including, "carcinoid" and "neuroendocrine" ......... can you spell that please, I said to the doctor. I had a low ki67 figure from a tissue sample taken percutaneously from my liver, it seemed pretty good that I was only 5 in a range of 0-100 but somehow the word 'indolent' did not seem to match the long list of metastases including the mesentery, the liver, the retroperitoneal cavity, the armpit, the clavicle. If that was not enough, there was also a long list of secondary effects including but not limited to "mesenteric fibrosis", "retroperitoneal…

Neuroendocrine Tumours (NET) – hiding in plain sight – an awareness post from Ronny Allan

Awareness, Patient Advocacy, , ,
When I was diagnosed, I didn’t even feel ill. It was therefore a bit of a shock being told I had metastatic cancer, advanced enough to kill me without treatment. It was hiding But it did make me think back to some minor irritants, or to be accurate what I thought were minor irritants, things that I could not explain, things that I did not think were serious enough to speak to a doctor.  And what would this doctor have said at the time? I was never misdiagnosed because I was never diagnosed with anything that wasn’t already there and documented.…

Bone metastases in Neuroendocrine Tumours (NET)

Patient Advocacy, , , , ,
Many of you will know that I am a stage IV small intestine NET and I have one bone metastasis (BM) reported. The initial evidence of this BM came from my very first Ga68 PET scan. It said "there is intense focal uptake of tracer in the right 11th rib".  This rib is at the bottom of the ribcage at the back of the body. Along with rib 12, they're called 'floating ribs' as only one end is joined to another part of the cage. The closest organs to this rib is the posterior liver and right kidney. I have…

What is Radioligand Therapy? When you browse the internet, you may see the term "Radioligand Therapy (RLT)" and wondered what it is. There's a simple explanation to what it is; and why you may be seeing more of it. Firstly, you will all be aware of Peptide Receptor Radionuclide Therapy (PRRT), right? Well that is just a type of RLT where the target is somatostatin receptors (SSTR). RLTs can have different targets. You may be seeing the term Radioligand Therapy more because this technology is starting to be used on other cancers but almost always different target routes. The obvious…

The Dethroning of Neuroendocrine Neoplasms as an Orphan Disease: US Incidence, Prevalence, and Survival in the 21st Century

Awareness, Patient Advocacy, , ,
USA - Prevalence of Neuroendocrine Neoplasms (NENs) breaches the Orphan Disease threshold for the first time (officially) The latest US SEER figures confirm that staggering increase in the prevalence of NENs. In that cross-sectional study which evaluated 145,477 NEN cases in the US, age-adjusted incidence rates increased 5.2-fold between 1975 and 2021, with an annual percentage change of 3% between 2000 and 2020, and the 20-year limited duration prevalence projected in the US population on January 1, 2021, was 243 896. Survival for all NENs improved, including for patients with distant-stage gastrointestinal and pancreatic NENs. And even this figure is understated…

Reframing Neuroendocrine Neoplasms Beyond “Rare”

Reframing Neuroendocrine Neoplasms Beyond “Rare”

Awareness, Patient Advocacy, , , ,
Neuroendocrine neoplasms (NENs) have outgrown the “rare disease” label. e.g. Across the U.S., UK, and Australia, they now rank among the most commonly diagnosed cancers — yet they remain under-recognised in mainstream healthcare circles, often misdiagnosed in primary and secondary care, but continue to be medically complex requiring specialist input which often arrives late. The Global Reality - examples These figures reflect improved diagnostics, rising awareness, and longer survival (thus the prevalence figures) — but they also expose a critical gap: prevalence has increased, but understanding has not appeared to keep up.  Some of  you might add that more specialist…

Every stripe is lost awareness

Sincer 2015, my message has not changed.  My message continues to be justified because since then, many important voices in the NEN community have repeated it!  However, there has been, and still remains, some instransigence, although some of that has now buckled in the face of the recent US SEER statistics. However, the buckling needs to spread and expand.  Unfortuantely, some elements of the NEN communmity remain entrenched in old thinking, in flawed thinking. I can only describe them as negative disruptors, clinging on to this old thinking. It seems like they refuse to change their mind or plan to…

Reports of my death have been greatly exaggerated….. the pitfalls of Artificial Intelligence (AI) I recently discovered — to my great amusement - that someone referred to me as “the late Ronny Allan.” While I appreciate the dramatic flair, I’d like to reassure everyone that I’m still very much alive, caffeinated, and actively moderating, educating, and occasionally ranting about neuroendocrine cancer.  To be fair, I do spend a lot of time digging through esoteric subjects such as pathology reports and clinical trial data, so perhaps someone mistook my silence for eternal rest.

Neuroendocrine Cancer: a needle in a haystack?

Patient Advocacy, , , , , , , , , , , ,
Reviewed and edited 6th December 2024 It's no secret that Neuroendocrine Cancer can be difficult to diagnose. Although earlier diagnosis is improving (as reported in the US SEER database report issued in 2017 and also in many other places), there is still a lot of ground to cover. There are a number of reasons why these Neoplasms are often difficult to correctly and quickly diagnose 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.Neuroendocrine Cancer is a heterogenous group…

Immunotherapy and Neuroendocrine Neoplasms

Updated 24th September 2025. Introduction There's a lot of Immunotherapy stuff out there!  The picture regarding its use in Neuroendocrine Neoplasms is not clear and there is no general roadmap printed.  I first heard of Immunotherapy for NETs following attendance 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…

Weekly update 22nd September 2025

Another helpful week with some good support on my social media outlets.  This is despite a reduction in new posts while I resolve some website issues.  I thank you if you  have supported my website via my social media accounts, particularly Facebook. So what are the highlights of last week?  Let's start with my Pheochromocytoma/Paraganglioma campaign.

The Treachery of Pheochromoctyomas and Paragangliomas – please think of it!

The Treachery of Pheochromoctyomas and Paragangliomas – please think of it!

A spotlight on NENs, A spotlight on NENs - Types, Patient Advocacy, , ,
Something came up in my timeline this week and I really enjoyed reading it.  I have many alerts set for various subjects including Pheochromocytomas and Paragangliomas.  Often an old published article is republished making it to my alert system and it got pushed up the timeline. It did seem like it was up to date but I eventually spotted it was from 2006! I appreciated some of the content because it had confirmed many parts of my knowledge about these interesting tumours. Two things stood out in this 2006 document:  Firstly, the mention of how many of these tumours are…

The 4 Cs – Causation, Correlation, Coincidence and Confounding Factors

The 4 Cs – Causation, Correlation, Coincidence and Confounding Factors

Patient Advocacy,
I learn a lot in my private patient group.  I also notice people jumping to conclusions on the cause of their issue when two variable things change at the same time.  It is pretty normal (and even I do it) to want to know what is causing a symptom but working out the causes is not always easy.  Treating the symptoms may be a more efficient use of time and energy.  Healthcare professionals are better placed to work this stuff out but in 2025, the internet, google, and even artificial intelligence can help the resourceful patient/caregiver.  But all of these…

Last week on Ronny Allan dot NET – 11-17 Aug 2025

Newsletters, Patient Advocacy
It's been an amazing week on my Facebook pages with some knock on effect on my website. I have been working on (and focussing on) my main Facebook page and I appreciate the support from you guys. Sharing a facebook post has proven to be very powerful for some of my posts on that page (Neuroendocrine Cancer). Between us we attracted many people from outside the community and many who were not part of the community but now are. Thank you. On my website, I only added a couple of posts last week: 1. 2025 Surveillance Update from Ronny Allan:…

2025 Surveillance Update from Ronny Allan: “No evidence of progressive disease”

2025 Surveillance Update from Ronny Allan: “No evidence of progressive disease”

Inspiration, Living with Neuroendocrine Cancer, Patient Advocacy, , ,
It's only a couple of weeks since I celebrated my 15th year since diagnosis of metastatic small intestine Neuroendocrine Tumour (NET) at Grade 2.  Thinking back to that period of my life, I'm happy but also slightly amazed to be celebrating such a long milestone having been diagnosed with cancer at Stage IV. I think it's a sign of many things, including but not limited to, early intervention by inquisitive healthcare professionals following vague symptoms, early access to a NET multidisciplinary team (MDT). Of course, human resilience must also be a factor. I didn't take this diagnosis lying down, I…

Surgery is risky but so is driving a car

Surgery is risky but so is driving a car

Treatment, , ,
I enjoyed reading an article written by Dr Eric Liu entitled The Complications of Surgery. In his article, Dr Liu, himself a surgeon, explains that surgery comes with risks, and patients should be made aware and be able to discuss these risks with their doctors. This got me thinking about my own experience which goes back to the autumn of 2010 when I first met my surgeon. At that time, there were a few articles about whether surgery or ‘biochemistry’ was the best treatment for certain types, grades and stages of Neuroendocrine Tumours (NETs). To some extent, these debates continue, particularly for pancreatic NETs.…

I may look well, but you can’t see my battles!

I may look well, but you can’t see my battles!

Patient Advocacy, ,
As I ponder my annual surveillance this summer and wonder what will be discussed, I also think about how far I’ve travelled and what I have been able to do.  It’s more than I thought I’d be able to do, I didn’t expect to still be here. Often, I feel lucky.  Perhaps an odd thing to say when I’m living with Stage IV cancer.  But those cards were dealt in 2010, and I now play with a new deck where I do have some control over how those cards are played.  As long as it’s not a flush! No pity please.…

NETTER-3 – Clinical Trial: [177Lu]Lu-DOTA-TATE in Patients With Grade 1 and Grade 2 Advanced GEP-NET

NETTER-3 – Clinical Trial: [177Lu]Lu-DOTA-TATE in Patients With Grade 1 and Grade 2 Advanced GEP-NET

Clinical Trials and Research, Patient Advocacy, Treatment, ,
Why is this trial important? The output of NETTER-2, suggested Lutathera for GEP-Grade 2 and 3 NETs could be used as a first line treatment. In some areas this appeared to be controversial.  The data from NETTER-1, which was focused on Grade 1 and 2 (less than ki67 of 10%), did not conclude the same, different aim. However, this appears to be the main aim of NETTER-3, to look at the data in the same way as NETTER-2 but for Grade 1 and 2 with similar criteria used on NETTER-1. You might say NETTER-3 is a follow on from NETTER-1 but…
