Neuroendocrine Cancer Hormonal Syndromes – Clinical Esoterica

Neuroendocrine Cancer Hormonal Syndromes – Clinical Esoterica

Awareness
One of the key awareness messages for Neuroendocrine Cancer is the hormonal syndromes that can often accompany the diagnosis for many people.  As it's a difficult disease to diagnose, many people struggle with these syndromes for some time before formal diagnosis of Neuroendocrine Cancer.  Some continue to struggle after. Neuroendocrine Cancer can often be uncannily quiet, but the tumours can be 'functional' and over-secrete certain hormones to add or introduce symptoms that mimic many other diseases or conditions, such as Irritable Bowel Syndrome, Menopause, Heart disease and Asthma.   In addition to common symptoms of flushing and diarrhea, others include generally feeling weak, fatigued, pain, agitated, anxious, dizzy, nauseous, acid reflux, skin irritation, anaemic, weight loss, weight gain, low blood sugar, high blood sugar, heart palpitations, headaches, sweating, high blood…

Neuroendocrine Cancer: Fibrosis – an unsolved mystery?

Neuroendocrine Cancer: Fibrosis – an unsolved mystery?

Living with Neuroendocrine Cancer, Treatment
What happened to me?Since I was diagnosed in 2010, I've always known I've had a fibrosis issue in the retroperitoneal area, as it was actually identified on my very first CT scan, which triggered my diagnosis.  Here's how the radiologist described it - "There is a rind of abnormal tissue surrounding the aorta extending distally from below the renal vessels. This measures up to 15mm in thickness".  He went on to describe that "almost certainly malignant".  The second and third scans would go on to describe as "retroperitoneal fibrosis" and "a plaque-like substance".  Interestingly the fibrosis itself does not appear to 'light up' on nuclear scans indicating it was not cancerous (see below).I really didn't know what to make of this issue at diagnosis, although I did know the aorta…

Neuroendocrine Cancer – tumour markers and hormone levels

Neuroendocrine Cancer – tumour markers and hormone levels

Patient Advocacy
BackgroundI 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 tissue,…

Telotristat Ethyl (XERMELO®) – an oral treatment for Carcinoid Syndrome Diarrhea not adequately controlled by Somatostatin Analogues

Telotristat Ethyl (XERMELO®) – an oral treatment for Carcinoid Syndrome Diarrhea not adequately controlled by Somatostatin Analogues

Treatment
What is Telotristat Ethyl?Telotristat Ethyl is a significant introduction to the treatment of Carcinoid Syndrome diarrhea. It's the first addition to the standard of care in more than 16 years and the first time an oral syndrome treatment has been developed.  The drug was previously known as Telotristat Etiprate but was changed to Ethyl in Oct 2016. 'Etiprate' was previously a truncation of 'ethyl hippurate'.  The brand name is XERMELO® 4th April 2022 updateSERB is pleased to announce it has acquired the rights from Ipsen to commercialize Xermelo® (telotristat ethyl) in Europe and other countries outside the US and Japan.  Xermelo® will be commercially available from SERB outside the US and Japan starting in July 2022.   The announcement appears to infer that SERB are working with BTG Specialty Pharmaceuticals to complete this task.

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…

Neuroendocrine Cancer – don’t break my heart!

Awareness, Living with Neuroendocrine Cancer, Survivorship, Treatment
Neuroendocrine Cancer has certain unique features whereby tumours can produce one or more symptoms which are known collectively as a syndrome.  Neuroendocrine Tumours secreting excess amounts of serotonin, can be accompanied by Carcinoid Syndrome which if not diagnosed and treated early enough, can lead to an additional complication known as Hedinger Syndrome (often known as Carcinoid Heart Disease (CHD)). However, very late diagnoses can present with CHD already in place.Excess serotonin, a hormone released by NETs into the bloodstream seems to be the prime and lead suspect for causing thick ‘plaques’ or fibrosis tissue within the heart muscle and damage to (mainly) the tricuspid and pulmonary valves on the right side of the heart which can become ‘tightly narrowed’ or ‘leaky’.  It's very similar to the reasons for mesenteric and peritoneal fibrosis…

Carcinoid vs Neuroendocrine

Carcinoid vs Neuroendocrine

Awareness, Patient Advocacy
OPINIONThere's a constant debate regarding the validity of the term 'Carcinoid'.  I've posted about this a few times and as far as I know, the debate has been raging for some years.EDIT MARCH 2022.  The latest classification system for Lung Neuroendocrine Neoplasms (NEN) confirms the word "carcinoid" is now a choice - the WHO Lung Committee bottled it.  I made my choice some years ago, I hope others follow suit.  Read more about changes to Lung NEN by clicking here. EDIT APRIL 2020.  The latest classification system for Neuroendocrine Neoplasms confirms the word "carcinoid" no longer forms part of the terminology used in Digestive System tumours (effectively removing the term from GEP NETs) - read more - click hereEdit May 2020.  So, what about other areas not included in GEPNETs above? Please note there…
