Don’t believe the hype – Neuroendocrine Cancer Myths debunked
Edited and refreshed 13th January 2026 There's a lot of inaccurate and out-of-date information out there. Some are just a lack of understanding, and some are caused by out-of-date websites. Often the problem is a result of patient forum myth spreading exacerbated by poor moderation in the groups concerned. Some can only be described as propaganda. Some of it even comes from uninformed doctors and bizarrely and disappointingly from NET advocate organisations. All the graphics below contain links to relevant blog posts. Myth 1: All Neuroendocrine Neoplasms will metastasise Simply untrue. They are a heterogeneous group of tumours. Read more…

Chemo or not Chemo – that is the question
I often see certain drugs for the treatment of Neuroendocrine Tumours (NETs) described as "chemotherapy". Although since I wrote the first edition of this post in 2016, I don't see it as much today in 2024. Education is a wonderful thing! I think there must be some confusion with more modern drugs which are more targeted and work in a different way to Chemotherapy. According to Mayo Clinic: "In many ways, cytotoxic chemotherapy is "targeted" at specific molecules that regulate progression through the cell cycle; however, these targets are generally not specific for tumour cells. Because systemic cytotoxic chemotherapy targets…
Neuroendocrine Cancer – it takes guts
The majority of Neuroendocrine Tumours (NETs) are slow growing (well differentiated). However, many tumours can be silent (non-functioning) for some years before they start to 'function' and inform you of their presence. Even then, it may take some time to work out the real cause as the symptoms can mimic regular ailments. Moreover, in most cases, the appearance of a functional tumour often indicates the disease has metastasised and could now be incurable. Some tumours will grow and metastasise without syndromes, i.e. they are non-functional. These may become functional at some point in the future. However, with most slow-growing NETs, this…

Lanreotide for Lung NETs – SPINET Clinical Trial
Reviewed and updated 30th July 2024. Phase III trial data update. Update 30th July 2024. This trial had a low particpation repsonse. Experts cited the main reason was the increasing use of SSAs for Typical and Atypical Lung NETs in clinical practice; as such, patients were reluctant to enroll in this study, with the risk of receiving a placebo, when they could access the active treatment with a prescription. The above is unfortunate but perhaps the wording of some approvals caused confusion about scope. Together with pragmatic compassionate use in cliniclal practice this has perhaps had an adverse affect in…
Diabetes – The NET Effect
Updated January 2026Originally published September 2018. My chest infection is now settled, as too is the excitement and apprehension behind my first ever Ga68 PET - the outcome of that is still a work in progress. Earlier this year, my thyroid 'lesion' on watch and wait was given a 'damping down' with the prescription of a thyroid hormone supplement but I await a re-ignition of that small bush fire downstream. Bubbling behind the scenes and clamouring for attention is the spiking of my blood glucose test results and I was very recently declared 'at risk' for diabetes with a score…

Chemotherapy for Neuroendocrine Cancer
Edited and checked April 2024 One of the unusual aspects of Neuroendocrine Cancer is that chemotherapy is not normally considered as a 'standard of care' or first-line treatment, unlike many other cancers. One exception is high grade (Grade 3) where it is very often a first and/or second-line therapy. This is particularly the case with poorly differentiated Neuroendocrine disease, by default labelled as Neuroendocrine Carcinoma (NEC). Many people think Chemotherapy has a short life span due to recent advances in medical science, some citing Immunotherapy as its replacement. However, it's far too early to write off chemotherapy which is still…
Somatostatin Receptor Positive Advanced Bronchial Neuroendocrine Tumors – PRRT vs Everolimus
US Trial I was delighted to see this clinical trial which looks at the efficacy of PRRT (Lu177 dotatate) vs the efficacy of Everolimus (Afinitor). The latter is approved for the treatment of adult patients with progressive, well-differentiated non-functional, neuroendocrine tumors (NET) of gastrointestinal (GI) or lung origin with unresectable, locally advanced or metastatic disease (US FDA wording, Europe is similar). What is this trial? This phase II trial studies the effect of lutetium Lu 177 dotatate compared to the usual treatment (everolimus) in treating patients with somatostatin receptor positive bronchial neuroendocrine tumors that have spread to other places in…

Targeted Therapy for Neuroendocrine Cancer – Everolimus (Afinitor)
What is Everolimus (Afinitor)? Manufactured by Novartis, this is a targeted biological therapy or more accurately, a mammalian Target of Rapamycin (mTOR) inhibitor. It works by stopping some of the signals within cells that make them grow and divide. Everolimus stops a particular protein called mTOR from working properly. mTOR controls other proteins that trigger cancer cells to grow. So everolimus helps to stop the cancer growing or may slow it down. The drug is also approved for Renal Cell Carcinoma (RCC) and hormone-receptor-positive advanced Breast Cancer. The drug is administered in oral form (tablet). The recommended dose for AFINITOR®…
Clinical Trials: Lenvatinib Efficacy in Advanced Neuroendocrine Tumours
Lenvatinib (LENVIMA) in Neuroendocrine Cancer — Updated January 2026 What is Lenvatinib? Lenvatinib is a targeted therapy known as a multikinase inhibitor. The brand name is LENVIMA. These drugs work by inhibiting multiple intracellular and cell‑surface kinases involved in tumour growth, angiogenesis, and metastatic progression. Targets include: VEGFR PDGFR FGFR c‑KIT Flt3 Because tumour progression typically involves multiple signalling pathways rather than a single driver, multikinase inhibition is a logical therapeutic strategy. How does it compare with other targeted therapies used in NETs? Sunitinib (Sutent) – a multikinase inhibitor targeting VEGF pathways; approved for pancreatic NETs. Everolimus (Afinitor) – an…
Sapanisertib – a drug on trial for Neuroendocrine Tumors (NET) with a pancreatic primary
Researchers are testing the drug Sapanisertib to see if it can halt the progression of pancreatic NETs (pNETs) which cannot be surgically removed, have not responded to other treatment, and have spread to other parts of the body. What is Sapanisertib? Sapanisertib is one of a group of targeted therapy drugs that interferes with tumor progression by inhibiting an enzyme known as mTOR which a tumor cell needs for growth. In fact this is the same technique used in Afinitor (Everolimus), already approved for NETs. It is also being tested in a number of different advanced cancers, including bladder, kidney, breast,…
Update: Management of Neuroendocrine Tumors
This is an excellent and positive video based overview of where we are with the Management of NETs. This is a presentation from a NET Specialist (who some of you may know) presenting to a "GI Malignancies" conference. This is therefore not only awareness of NETs, it's also some good education for non NET GI experts who may only know the very basics. Useful for patients too! I met Dr Strosberg in Barcelona (ENETS 2017) and thanked him for his presentational and scientific paper output which I often use in my articles. The classification picture is good as it explains…

NETwork with Ronny © – Community Newsletter MAY 2017
Hi NETworkers! Welcome to my monthly 'Community' newsletter. This is April 2017's monthly summary of Ronny Allan's Community news, views and ICYMI (in case you missed it!). This year, it's occurred to me that I've gone beyond just being known as a 'blog' and have transformed into something with a much wider focus within the NET Community and beyond. I've added a new section called NET News. This is a catch up of stuff I've accumulated over the past month but perhaps not yet posted or simply want to emphasise what I think is significant news about NETs or might impact…
Recent Progress in NET Management – Positive presentation from Jonathan R Strosberg MD
I recently wrote a blog called Neuroendocrine Cancer – Exciting Times Ahead! I wrote that on a day I was feeling particularly positive and at the time, I wanted to share that positivity with you. I genuinely believe there's a lot of great things happening. Don't get me wrong, there's a lot still to be done, particularly in the area of diagnosis and quality of life after being diagnosed. However, this is a really great message from a well-known NET expert. In an interview with OncLive, Jonathan R. Strosberg, MD, associate professor at the H. Lee Moffitt Cancer Center in Florida, discussed…
Neuroendocrine Cancer – Exciting Times Ahead!
In the last 12-24 months, there seems to have been announcement after announcement of new and/or upgraded/enhanced diagnostics and treatment types for Neuroendocrine Cancer. Scans, radionuclide therapies, combination therapies, somatostatin analogues, biological therapies, etc. Some of the announcements are just expansions of existing therapies having been approved in new (but significant) regions. Compared to some other cancers, even those which hit the headlines often, we appear to be doing not too badly. However, the pressure needs to stay on, all patients need access to the best diagnostics and treatments for them; and at the requisite time. There's even more in the pipeline and I'm hoping…

Clinical Trial: Neuroendocrine Cancer drug in the pipeline – Fosbretabulin Tromethamine CA4P (incl combo with Everolimus)
{NEW} added 4 June 2019 From ASCO 2019 conference extract: Of the 17 patients enrolled, 16 completed the 12-week trial. One patient was not evaluable due to noncompliance. No DLTs were observed at day 21. The highest dose of 10 mg daily oral everolimus in combination with weekly 60mg/m2 IV fosbretabulin is the RP2D. No grade 4 or 5 toxicities were noted. Grade 3 toxicities were seen in 5 patients; abdominal pain and hyperglycemia (not related to study drug), fatigue (possibly related), decreased lymphocyte count and anemia (related). Several patients had delay in treatment due to grade 2 AE’s (GI…
PRRT and the NHS England Cancer Drugs Fund (now archived information)
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…
