Genetics and Neuroendocrine Tumors

Genetics and Neuroendocrine Tumors

Awareness, Living with Neuroendocrine Cancer, Survivorship
Hereditary genetics.....where to focus In recent years, it has become increasingly apparent that a number of Neuroendocrine tumours arise as a result of germline genetic mutations and are inherited in an autosomal dominant pattern. The number of genes implicated is increasing and I cannot guarantee this post will contain all of them. Apparently, 5-10% of NETs are estimated to have a hereditary background. Hereditary syndromes associated with these include Multiple Endocrine Neoplasia (MEN), Von Hippel Lindau (VHL), Neurofibromatosis Type 1 (NF1), Tuberous Sclerosis (TS) and others. People who have a genetic condition may present with the tumors (perhaps along with an associated functional hormone syndrome) and so the genetic condition if there is one, may not be known at this point.

Neuroendocrine – don’t let it be a Crisis

Neuroendocrine – don’t let it be a Crisis

Update 15th November 2021.   A study presented at NANETS 2021 produced data to suggest the causes and treatment for carcinoid crisis have been wrong and that a new model is required.  Read the article here or by clicking on the picture.Author's note:  This is probably a controversial conclusion in some circles and it's worth pointing out that so-called 'carcinoid crisis' isn't going away, just the need for time-consuming and expensive, and apparently ineffective according to the study, perioperative protection.  And the study also noted that medication to treat complications was still required.  I don't believe we should immediately dismiss this conclusion as one of the authors is a 'big hitter' NET Specialist surgeon (Dr Rodney Pommier) whose job is to keep patients safe on the operating table. The original article…

Neuroendocrine Cancer – tumour markers and hormone levels

Neuroendocrine Cancer – tumour markers and hormone levels

A Spotlight on NENs - Testing Series, Patient Advocacy
BackgroundSome people on hear the terms "tumour markers" and "hormone levels" when they are diagnosed with Neuroendocrine Cancer.  Most of them will 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…
