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

Republished and reformatted and reviewed 1st September 2024.  Original published 31st March 2016.  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® Who is the drug for?The drug may be of benefit to those whose carcinoid syndrome diarrhea is not adequately controlled by somatostatin analogues…
The Syndromes of Neuroendocrine Cancer – Early Signs of a Late Diagnosis

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

Updated 14th June 2024 The Syndromes of Neuroendocrine Cancer - Early Signs of a Late Diagnosis There are some curious things about Neuroendocrine Cancer (NETs elsewhere in the text on the basis that a hormonal syndrome is extremely rare in Neuroendocrine Carcinoma (NEC)).  One of them 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…
Neuroendocrine Cancer: Fibrosis – an unsolved mystery?

Neuroendocrine Cancer: Fibrosis – an unsolved mystery?

What happened to me?Since I was diagnosed in 2010, I've always known about a fibrosis issue in my retroperitoneal area.  It was identified on the 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".  Followed by a statement saying that it was "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…
Neuroendocrine Cancer – don’t break my heart!

Neuroendocrine Cancer – don’t break my heart!

Neuroendocrine Cancer has certain unique features whereby tumours can produce one or more symptoms which are known collectively as a syndrome.  Some doctors may refer to this as a functional tumour. Neuroendocrine Tumours secreting excess amounts of serotonin sufficiently to develop a syndrome currently called Carcinoid Syndrome, which if not diagnosed and treated early enough, or the levels of serotonin ae not controlled following diagnosis, can lead to an additional complication known as Hedinger Syndrome (also known as Carcinoid Heart Disease (CHD)). However, late diagnoses can present with CHD already in place and in some cases, may have led to…
Carcinoid vs Neuroendocrine

Carcinoid vs Neuroendocrine

OPINION  - There'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.  This post was originally generated in April 2015 (and hasn't changed that much!). EDIT MARCH 2024. There is now a consolidated Endocrine/Neuroendoceine Tumour classification system (Blue Book).  Still in print but you can see a summary of changes by clicking here. This change should provide some leverage to Neuroendocrine committees particularly about what things should be called. EDIT MARCH 2022.  The latest classification system for Lung…

European Neuroendocrine Tumor Society (ENETS) 2022 Guidance Paper for Carcinoid Syndrome and Carcinoid Heart Disease

Author's commentMy 'Spotlight' on Carcinoid Syndrome may be easier reading for some but for those who wanted to dive into NET Specialist authored guidelines, this set from ENETS will be of use.Scope.  Carcinoid Syndrome (CS) and Carcinoid Heart Disease (CHD) formally known as Hedinger Syndrome) are related in that the latter is a rare and complex cardiac complication occurring in patients with advanced NETs and CS.  CS is predominantly encountered in patients with well-differentiated NETs of intestinal origin, followed by lung NETs, and only in a minority of patients with pancreatic, ovarian, thymic, or unknown origin (UKO) NETs.  It follows…

Neuroendocrine Cancer – Clinical Esoterica

The good news ....... things are improving, the latest US figures confirm two major changes:1.  Most diagnoses are now early stage2.  The disease is no longer rare and no longer an orphan diseaseOne 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…
A spotlight on 5-HIAA

A spotlight on 5-HIAA

Background. It's important to note that not every type of Neuroendocrine Neoplasm will get the same tests due to the heterogenous nature of this cancer type. Some are more specific than others.  A wide range of tests may be necessary at diagnosis if the type of NET is not clear. This post will cover one of the main tests to check for a common type of Neuroendocrine Tumour (NET) that is known to secrete excess amounts of the hormone Serotonin leading to symptoms indicative of Carcinoid Syndrome.  These tumours are often labelled using the antiquated and misnomer term ‘Carcinoid Tumour’ but more…
Neuroendocrine Cancer Hormonal Syndromes – a witch’s brew

Neuroendocrine Cancer Hormonal Syndromes – a witch’s brew

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…
