There’s a lot of inaccurate and out of date information out there. Some is just a lack of understanding, some caused by out of date websites, often as a result of patient forum myth spreading. Some can only be described as propaganda. Some of it even comes from doctors and NET advocate organisations.
Myth 1: All Neuroendocrine Tumours are benign
Not true. By any scientific definition, the word ‘tumour’ means ‘an abnormal mass of tissue that results when cells divide more than they should or do not die when they should. Tumours may be benign (not cancerous), or malignant (cancerous)’. Sure, some NETs will be benign but a tumours which spreads away from the primary site cannot be benign by any scientific definition. However, since the World Health Organisation (WHO) 2010 classification for digestive systems, the situation has been based on the concept that all NETs have malignant potential, and therefore abandoned the division into benign and malignant NETs and tumours of uncertain malignant potential. This has been reinforced in the 2017 Endocrine update to include clarification for endocrine organ types of NET including Pheochromocytoma and subsequently (and more forcefully) in the 2019 Digestive Systems update. Read more here. The word ‘Carcinoid’ is inextricably linked with this issue – read here why we need to stop using the term to help fight the benign myth.
Myth 2: Neuroendocrine Tumours is a terminal condition
Not true. By any definition of the word terminal in a medical diagnostic context, most NET patients have a good prognostic outlook, even those with metastatic and incurable variants of the disease. Read more here.
Myth 3: Carcinoid is another word for Neuroendocrine Tumours
Not true. Carcinoid is a very old term and was phased out years ago. Carcinoid is not mentioned in the latest WHO Classification schemes for Neuroendocrine Neoplasms (a term covering Neuroendocrine Tumours and Neuroendocrine Carcinoma). Unfortunately, the problem is exacerbated by organisations and individuals who still use the word. Also, those who use the following terms:
- “Carcinoid Neuroendocrine”,
- “Neuroendocrine Carcinoid”,
- “Carcinoid and Neuroendocrine”,
- “Neuroendocrine and Carcinoid”,
- “Carcinoid NETs” or “CNET”
These are all contextually incorrect and misleading terms (not to mention the bad grammar). ENETS, NANETS and NCCN publications are gradually phasing the word out except in relation to Carcinoid Syndrome (and even then there could be easy solutions for this). Doctors (including some NET specialists) and patient organisations need to catch up. Read more here and here.
Myth 4: All NET patients get ‘carcinoid syndrome’
Not true. Firstly, many NETs are non-functional; and secondly, carcinoid syndrome is only one of a number of “NET Syndromes” and is only associated with serotonin secreting NETs. However, the issue is further confused by those who use the word ‘Carcinoid‘ to incorrectly refer to all NETs and use Carcinoid Syndrome to refer to all NET Syndromes. Read more here.
Myth 5: Neuroendocrine Neoplasms are rare
Myth 6a: Steve Jobs had Pancreatic Cancer
Not true. Steve Jobs had a Neuroendocrine Tumour of the Pancreas. Ditto for a few other famous names. Read more here.
Myth 6b: Aretha Franklin had Pancreatic Cancer
Not true. Aretha Franklin had a Neuroendocrine Tumour of the Pancreas. Ditto for a few other famous names. Read more here.
Myth 7: I’m not getting chemotherapy, I must be doing OK?
Not true. For some cancers or some sub-types of cancers, although it remains an option in certain scenarios, chemotherapy is not particularly effective, e.g. some types of Neuroendocrine Cancer (NETs). In general, well differentiated NETs do not normally show a high degree of sensitivity to chemotherapy, although some primary locations fare better than others. However, many of the treatments for NETs are somewhat harsh, have long-term consequences, and have no visible effects. NET patients are often said to “look well” but that doesn’t mean they are not struggling behind the scenes or under the surface. Read more here. P.S. Afinitor (Everolimus), Sutent (Sunitinib) are not chemo – Read more here.
Myth 8: All diarrhea is caused by carcinoid syndrome
Not true. It could be one of the other syndromes or tumor types or a side effect of your treatment. Check out this post.
Myth 9: Neuroendocrine Tumours is a ‘good cancer’
Not true. Simply, no cancer is good. Some are statistically worse than others in prognostic terms, that’s true…… but living with NETs is very often not a walk in the park. However, no one cancer is better to get than any other – they’re all bad. Read more here.
Myth 10: Every NET Patient was misdiagnosed for years
Not true. Many NET Patients are correctly diagnosed early on in their investigation and in a reasonable time. This myth is perpetuated because of two things: firstly, on forums, the ratio of long-term misdiagnosis is high creating a false perception; and secondly, the method of capturing patient surveys is not extensive enough – again creating a false perception. In fact, the latest and largest database analysis from US indicates earlier diagnosis is improving, with more and more NETs being picked up at an early stage. Read more here.
Myth 11: Somatostatin Analogues are a type of Chemotherapy
Not true. Somatostatin Analogues (e.g. Octreotide and Lanreotide) are not chemotherapy, they are hormone inhibiting drugs. They are more biotherapy. As the drugs latch onto somatostatin receptors, they are more targeted than systemic. For the record, Everolimus (Afinitor) and Sunitinib (Sutent) are not chemotherapy either. Read more here.
Myth 12: Stuart Scott (ESPN) and Audrey Hepburn had Neuroendocrine Cancer.
Not true. This is a common misunderstanding within the community. They both had Pseudomyxoma Peritonei (PMP). Read more about PMP here.
Myth 13: I’ve been diagnosed with Neuroendocrine Tumours – my life is over
Not true. Many patients live a very long time and lead fairly normal lives with the right treatment and support. It’s difficult but I try not to use ‘I can’t’ too much. Read more here.
Myth 14: There are only a handful of Neuroendocrine specialists in the world
Not true. There are many specialists in many countries. Get links to specialists by clicking here
Myth 15: The Ga68 PET scan is replacing the CT and MRI scan in routine surveillance for all NET Patients
Not true. It is actually replacing the Octreotide Scan for particular purposes, or will eventually. Read more by clicking here.
Myth 16: All NET Patients are Zebras
Not true. They are in fact human beings and we should treat them as such. Please don’t call me a zebra, I and many others don’t appreciate it. Please don’t use the term on my social media sites, the comment or post will be removed. Sorry but I refuse to perpetuate this outdated dogma. Read why here:
Myth 17: Multiple Endocrine Neoplasia (MEN) is a type of Neuroendocrine Tumour
Not true. Multiple Endocrine Neoplasia are syndromes and inherited disorders not tumours. You can actually have MEN and not have any tumours. However, these disorders can put people at more risk of developing Neuroendocrine or Endocrine Tumours. Read more here
Myth 18: Palliative Care means end of life or hospice care
Not true. Palliative care is specialized medical care that focuses on providing patients relief from pain and other symptoms of a serious illness. A multidisciplinary care team aims to improve quality of life for people who have serious or life-threatening illnesses, no matter the diagnosis or stage of disease. Read more here
Myth 19: Serotonin is found in foods
Not true. Serotonin is manufactured in the body. Read more here
Myth 20: NETs cannot be cured
Not true. If caught early enough, some NETs can be treated with curative intent (totally resected with margins) with little or no further follow up. It says this in ENETS and NANETS publications which are authored by our top specialists. If we can’t believe them, who can we believe? Read more here.
Myth 21: Pancreatic Enzyme Replacement Therapy (Creon etc) is only for pancreatic patients
Not true. It’s for any patient who is exhibiting exocrine pancreatic insufficiency. Read more here.
Myth 22: High Grade means Neuroendocrine Carcinoma
Not true. Since 2017, Grade 3 (high grade) comprises well differentiated tumours (NETs) and poorly differentiated tumours (Neuroendocrine Carcinomas or NEC). Only poorly differentiated tumours are carcinomas. Read more here.
Myth 23: Chemo doesn’t work for NETs
Not entirely true. Chemo is commonly used on Grade 3 (high grade), particularly poorly differentiated. Also used in some grade 2 scenarios. Read more here.
Myth 24: “NET Cancer” is an official term
Not true. Aside from the ridiculous grammar “Neuroendocrine Tumour Cancer” is not the way to describe our cancer. The correct terms can be found by reading here
