Neuroendocrine Tumours: a spotlight on Pheochromocytoma and Paraganglioma

Neuroendocrine Tumours: a spotlight on Pheochromocytoma and Paraganglioma

Awareness, Patient Advocacy, Technical NETs
  I 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 - incidence rate 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 (the remainder…

Neuroendocrine – don’t let it be a Crisis

Neuroendocrine – don’t let it be a Crisis

Awareness, Living with Neuroendocrine Cancer, Patient Advocacy, Technical NETs, Treatment
  The word 'crisis' has a wide range of meanings and it's well used in the media to catch the reader's attention. Lately, the terms 'political crisis', financial 'crisis' and 'constitutional crisis' appear almost daily in media headlines. In a previous life, the term 'crisis management' was used daily in the work I was undertaking as I went from problem to problem, dampening or putting out fires (..... that's a metaphor!).  Thinking back, my adrenaline (epinephrine), norepinephrine, and cortisol must have been very busy!  However, in the world of Neuroendocrine Tumours (NETs), 'crisis' has a very significant meaning and its very mention will make ears prick up.  The word 'crisis' is normally spoken or written using the term 'Carcinoid Crisis' given it is normally associated with those who have carcinoid syndrome.  However, I've studied and researched and it…

Neuroendocrine Cancer – tumour markers and hormone levels

Neuroendocrine Cancer – tumour markers and hormone levels

Awareness, Diet and Nutrition, Living with Neuroendocrine Cancer, Patient Advocacy, Survivorship, Technical NETs, Treatment
I think most people 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 much higher levels in cancerous conditions. These substances can be found in the blood, urine, stool, tumour…

Neuroendocrine Cancer Nutrition Series Part 4 – Food for Thought?

Neuroendocrine Cancer Nutrition Series Part 4 – Food for Thought?

Diet and Nutrition, Living with Neuroendocrine Cancer, Patient Advocacy, Survivorship, Technical NETs
  Nutrition is an important subject for many cancers but it is particularly important for Neuroendocrine Cancer.  In the previous parts of this series I focused on the following: Article 1 - Vitamin and Mineral Challenges.   This was co-authored by Tara Whyand, UK's most experienced NET Specialist Dietitian.  This blog provides a list of vitamins and minerals which NET Cancer patients are at risk for deficiencies, together with some of the symptoms which might be displayed in a deficiency scenario. Article 2 - Malabsorption.  Overlapping slightly into Part 1, this covers the main side effects of certain NET surgical procedures and other mainstream treatments. Input from Tara Whyand. Article 3 - 'Gut Health'.  This followed on from the first two blogs looking specifically at the issues caused by small intestine bacterial overgrowth…

Neuroendocrine Cancer – Horrible Hormones

Neuroendocrine Cancer – Horrible Hormones

Awareness, Living with Neuroendocrine Cancer, Technical NETs
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 ........like a lot of other things in life I suppose! The presence of over-secreting hormones (often called peptides throughout) is useful to aid diagnosis albeit it often (but not always) means the tumours have metastasized. It's also a frequent indication that the person has an associated NET syndrome. This is a really complex area and to understand the hormone problems associated with Neuroendocrine Cancer, you need to have a basic knowledge of the endocrine and neuroendocrine systems.  I've no intention…
