A Spotlight on Lung Neuroendocrine Neoplasms

A Spotlight on Lung Neuroendocrine Neoplasms

Awareness
WHO Classification of Tumours, 5th Edition, Volume 5: Thoracic TumoursThe aim of this spotlight is to provide a summary of the latest information on Lung Neuroendocrine Neoplasms (NEN) including the latest terminology, epidemiology data, and guidelines.   This follows the publication of the Thoracic WHO classification 5th edition (2021): terminology and criteria for neuroendocrine neoplasms (Blue Book).  This book has been anticipated to see if the panel compiling this follows the lead of the Gastroenteropancreatic Neuroendocrine Neoplasms (GEPNEN) editions issued in 2017 (Endocrine) and 2019 (Digestive systems) by removing the antiquated misnomer term ''Carcinoid" in line with the recommendations made by senior NEN doctors in 2020 to have commonality across all blue books.

The Heterogeneity of Grade 3 (High grade) Neuroendocrine Neoplasms

The Heterogeneity of Grade 3 (High grade) Neuroendocrine Neoplasms

Awareness, Patient Advocacy
Reviewed and updated 14th March 2022High Grade - the forgotten patient group?When reading articles in the mainstream media, found in medical publications; and even listening to doctors speak about my disease, it's clear that the focus is on the term "Neuroendocrine Tumours" or NET for short.  Many websites of advocate foundation organisations and specialist scientific organisations, all still use the term "NET" in their naming.  I too am guilty of having a large Facebook site falling into this category.  It's little wonder that those with high grade disease can often feel like the forgotten patient group.  Clearly all the aforementioned organisations support all patients regardless of grade, but it's true to say that the naming and general use of terminology continues to fall behind. It's also true that the term…

Grading and Staging – Neuroendocrine Neoplasms (incorporating WHO 2021 changes)

Patient Advocacy
One of the most discussed and sometimes confusing subjects on forums is the staging and grading of Neuroendocrine Neoplasms (NENs). Mixing them up is a common error and so it's important to understand the difference despite the apparent complexity. If I was to make a list of questions for my specialist/Oncologist at diagnosis, it would include "What is the stage, grade and differentiation of my cancer". To enable me to synchronise with the documented guidance, I'm going to use the following WHO 2019 approved terms in this post and then provide an update of the key WHO 2019 changes below.Neuroendocrine Neoplasm (NEN) - all types of Neuroendocrine tumour of whatever grade (please note Neoplasm is another word for tumour)Neuroendocrine Tumour (NET) - all well-differentiated tumours, Grade 1,2 or 3 (an…
