Von Hippel-Lindau (VHL) Syndrome – Ronny Allan – Living with Neuroendocrine Cancer

Tag: Von Hippel-Lindau (VHL) Syndrome

Von Hippel-Lindau syndrome is an inherited disorder characterized by the formation of tumors and fluid-filled sacs (cysts) in many different parts of the body. Tumours may be either noncancerous or cancerous and most frequently appear during young adulthood; however, the signs and symptoms of von Hippel-Lindau syndrome can occur throughout life. Tumours called hemangioblastomas are characteristic of von Hippel-Lindau syndrome.

Genome methylation accurately predicts neuroendocrine tumor origin – finding Neuroendocrine Neoplasms of unknown primary

Clinical Trials, Patient Advocacy

Share on facebook Facebook Share on twitter Twitter Share on pinterest Pinterest Share on whatsapp WhatsApp Share on email Email It's estimated that around 5-10% of Neuroendocrine Neoplasms (NENs) have an unknown primary - what that means is cancer cells have been found in the body but the place the cancer began remains unknown. I wrote about this issue in more depth in my article "Needle in a haystack" - you can read that here. In that article you will note that NET specialists through their knowledge and understanding of the behaviour of these comped tumours, can often drill down and gather various pieces of evidence to help narrow down the primary location. However, this new study would indicate they could have access to a new tool to be able…

Neuroendocrine Tumours: a spotlight on Pheochromocytoma and Paraganglioma

Awareness, Patient Advocacy

I spend a lot of time talking about the most common forms of Neuroendocrine Tumours (NETs), but what about the less well-known types? As part of my commitment to all types of NETs, I'd like to shine a light on two less common tumour types known as Pheochromocytomas and Paragangliomas - incidence rate approximately 8 per million per year. They are normally grouped together, and the definitions below will confirm why. If you think it's difficult to diagnose a mainstream NET, this particular sub-type is a real challenge.So, let's get definitions out of the way:Pheochromocytomas (Pheo for short)Pheochromocytomas are tumours of the adrenal gland that produce excess adrenaline. They arise from the central portion of the adrenal gland, which is called the adrenal medulla (the remainder of the gland is…

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…
