Neuroendocrine Cancer: Fibrosis – an unsolved mystery?

Living with Neuroendocrine Cancer, Technical NETs, Treatment

Background It has long been observed that certain Neuroendocrine Tumours (NETs) are often associated with their ability to secrete hormones and these substances are thought to be responsible for the collection of symptoms which include (but not limited to) diarrhea, flushing and wheezing. One of the lesser known aspects of this disease is the development of fibrosis, both local and distant. These fibrotic complications may lead to considerable morbidity. They can also result in incidental diagnoses of NETs after causing abdominal obstructions. The most well known form of fibrosis is 'Hedinger Syndrome' (so-called Carcinoid Heart Disease) tightly associated with midgut NETs and will not be covered further. However, mesenteric fibrosis is actually more common and also associated with midgut NETs. There are other less common locations involved including retroperitoneal fibrosis,…

“What are you doing this afternoon”

Awareness, Living with Neuroendocrine Cancer

On 8th July 2010, I was sat in front of a secondary care consultant, his speciality was colorectal. I asked specifically for this consultant for two reasons, firstly, he carried out a colonoscopy some 20 months previously which turned out to be negative. Secondly, my GP had referred me to the iron deficiency anaemia clinic, and they wanted to do ….. a colonoscopy. I changed that plan because this "non-issue" was dragging on; quite frankly I wanted it to be resolved quickly, and I wanted it to be resolved in my favour - after all, I wasn't actually ill! Rewind two months, I had an incidental set of blood tests ordered by a nurse following a routine visit to my local medical centre (....... "I think I've lost a bit…

Surgery for Neuroendocrine Neoplasms – to cut or not to cut?

Living with Neuroendocrine Cancer, Patient Advocacy, Survivorship, Technical NETs, Treatment

OPINION - nothing in here should be taken as advice from the author. On paper, surgery remains the only potentially 'curative' option for Neuroendocrine Tumours (NETs) but there are stage, grade and anatomical constraints to that opinion. Many people get 'twitchy' about any inference of the 'C word' (cure) but our most eminent NET specialists use the term frequently including in the major treatment guidelines. I use the word 'curative' with some reservations because for many who are diagnosed at an advanced stage, surgery will not cure but will debulk or cytoreduce as much tumour as possible in order to palliate symptoms and improve quality of life. This is a big deal because NETs is one of a small number of cancers where debulking surgery can often provide a survival…

Does your body now have an extra organ? The MESENTERY

Living with Neuroendocrine Cancer

One of the very first words I heard at diagnosis was the word "Mesentery". In the news today is the announcement that is now might just be a new organ following accepted findings from research conducted in the University of Limerick Ireland. I always knew it was something which held the small and large intestines in place within the abdomen so like many others, I just thought it was some kind of membrane type structure and I also knew there was some kind of interaction with the peritoneum, another word which I was to become familiar with. This is an important area for NET patients as many will have mesenteric involvement in their disease. I've read reports of a primary mesenteric tumour although it's mainly a site for secondary disease (metastasis). It's no surprise…

Serotonin – the NET effect

Awareness, Diet and Nutrition, Living with Neuroendocrine Cancer, Technical NETs

[caption id="attachment_14036" align="aligncenter" width="750"] A team of researchers from Case Western Reserve University School of Medicine have used high-powered microscopes for the first time to view serotonin activating its receptor[/caption]BackgroundI'd never heard of Serotonin until I was diagnosed with Neuroendocrine Cancer in 2010. It is frequently discussed, often with contrasting views from the respondents. One common assumption/question is that it is responsible for many things that can go wrong with Neuroendocrine Cancer patients who have serotonin-producing tumours. "It's the hormones" is an easy assumption to make or an easy answer to give in response to a complex set of circumstances. It's difficult to get a definitive answer and the science behind the behaviour of our hormones isn't really 100% tied down.You may see serotonin referred to as a 'neurotransmitter', a…

Surgery is risky but so is driving a car

Survivorship, Treatment

I enjoyed reading the recent blog 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. Surgery for certain NETs in certain scenarios is a controversial issue for NETs - as outlined in this article - to cut or not to…
