Neuroendocrine Neoplasms (NEN) – genetic related syndromes

Neuroendocrine Neoplasms (NEN) – genetic related syndromes

Awareness, Patient Advocacy
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 being conveyed. However, after studying this subject, I can tell you it is a very complex area and difficult to explain and then understand in a single paragraph.  Even these widely accepted definitions don't make it any more understandable!  The terms ‘hereditary’ and ‘familial’ look like synonyms and are frequently used interchangeably but are two different concepts. ‘Hereditary’ is most commonly used when referring to diseases with a known genetic cause whereas ’Familial’ disorders are those which appear to have a genetic component, affecting more family members than would be expected by chance alone. However,…

In my article 'Ever wonder what caused your NET', I concluded that currently, the only known scientifically explained causes for NETs were hereditary/genetic in nature.  This is mostly associated with those who have MEN syndromes (yes, they are a syndrome not a type of tumour)[caption id="attachment_13063" align="aligncenter" width="530"] Click to read my MEN article[/caption]There also strong connections with and a few other less common types of NET including Pheochomocytoma/Paraganglioma (Pheo/Para) and Medullary Thyroid Carcinoma (MTC) (the familial version of MTC is often referred to as FMTC). However, please note this does not mean that all those diagnosed with pancreatic, parathyroid, pituarity, Pheo/Para and MTC tumours, will have any hereditary or genetic conditions, many will simply be sporadic tumors.[caption id="attachment_16075" align="aligncenter" width="640"] Click to read my article on Pheochromocytoma and Paraganglioma[/caption]In recent…

In 2013, just when I thought everything seemed to be under control, I was told I had a 'lesion' on the left upper lobe of my thyroid.  At the time, it was a bit of a shock as I had already been subjected to some radical surgery and wondered if this was just part of the relentless march of metastatic NET disease.  The thyroid gland does in fact get mentioned frequently in NET patient discussions but many of the conversations I monitored didn't seem to fit my scenario - cue relentless study! I've been meaning to write this blog for some time but here is a synopsis of my research translated into 'patient speak'.  This is intentionally brief, it's a big subject.  I'll finish off with an update on where I…

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…

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

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

Awareness
One of the curious things about Neuroendocrine Cancer (NETs elsewhere in the text) 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 Neuroendocrine Cancer very difficult to diagnose quickly.  It's a very devious disease.It's NOT all about Carcinoid Syndrome!Most people think of Carcinoid Syndrome when they discuss NETs. Anyone suggesting that all NET patients get carcinoid syndrome or that all symptoms of NETs are caused by carcinoid…
