Serotonin not in the brain, mainly found in the gut.

Serotonin – it’s a no-brainer!

OPINIONThere is constant discussion about the effects of serotonin-producing tumours and issues of depression, anxiety, and 'rage'. However, it's a really complex issue for laypeople and I have no intention of trying to resolve it in this article. However, it's clear to me from listening and reading these discussions in patient forums for many years, that most of the discussion appears to be based on years of unsubstantiated and unmoderated debate inside patient forums without professional input. This is not an attempt to bash patient leaders and forum administrators, because a full understanding of these issues needs a much wider moderation. I've spent a considerable time researching and analysing what science is known and I can tell you now that the behaviour of serotonin in the human body is not…

Flower power and the happy hormones

Inspiration, Living with Neuroendocrine Cancer

One of the featured pictures below is a sunflower from 2015, something I planted with my own hands, and it grew taller than me (not difficult), even taller than my garden fence (more difficult). Of course, I have to mention my wife Chris because she does infinitely more gardening than I do, and she would have nurtured the sunflower from start to finish after I planted it. Nonetheless, I still felt a remarkably close association with the outcome! It made me happy just to look at it! My most liked Facebook posts in 2020 (the year of COVID) related to plant and forest pictures and there is a reason flowers proved to be more popular than my other posts. Flowers, particularly with vibrant colour, stimulate our happiness hormones, including serotonin. I…

What is Carcinoid Syndrome? Carcinoid syndrome (CS) is the most frequent hormonal complication accompanying neuroendocrine neoplasms (NENs) and is defined by chronic diarrhoea and/or flushing in the presence of systemic elevated levels of serotonin or its metabolite 5-hydroxyindolacetic acid (5-HIAA). Importantly, other causes of these symptoms should be considered and investigated depending on the clinical presentation. CS […]

Somatostatin Receptor Positive Advanced Bronchial Neuroendocrine Tumors – PRRT vs Everolimus

I was delighted to see this clinical trial which looks at the efficacy of PRRT (Lu177) vs the efficacy of Everolimus (Afinitor). The latter is approved for the treatment of adult patients with progressive, well-differentiated non-functional, neuroendocrine tumors (NET) of gastrointestinal (GI) or lung origin with unresectable, locally advanced or metastatic disease (US FDA wording, […]

Opinion: Let’s attack Cancer metaphors

Since I started blogging, I’ve read dozens of articles on the subject of ‘cancer metaphors’ and in particular their use in describing cancer experiences with the words ‘fight’, ‘battle’ and other ‘military’ sounding terms. The authors say that perhaps this is not the best language to use. One author used the term ‘violence’ to describe these […]

A review of November 2023 on RonnyAllan.NET – Living with Neuroendocrine Cancer

November is always busier as I help spread awareness for 10th Nov (remembering that every day is 10th Nov on my site!). I also managed to push out quite a few blogs, some ‘remasters’ from 2014 but with their originality from that time. Others include the ENETS Guideline series, a work in progress. I’m thankful […]

European Neuroendocrine Tumor Society (ENETS) 2023 guidance paper for Digestive Neuroendocrine Carcinoma

This ENETS guidance paper, developed by a multidisciplinary working group, provides up-to-date and practical advice on the diagnosis and management of digestive neuroendocrine carcinoma, based on recent developments and study results. These recommendations aim to pave the road for more standardized care for our patients resulting in improved outcomes. However, it’s true to say that […]
