Somatostatinoma – Ronny Allan – Living with Neuroendocrine Cancer

Tag: Somatostatinoma

Somatostatinomas are functional neuroendocrine tumour that arise from tumour cells originated from specialised hormone-producing cells in the pancreas or duodenum (first part of small intestine).

is a very rare type of NET, with an incidence of one in 40 million persons. These tumours produce excess somatostatin arise from the delta cells in the pancreas, although these cells can also be present in duodenal/jejunum tissue where approximately 40% of these tumours occur. Somatostatin is a naturally occurring peptide that inhibits the function of almost all gut hormones

(author’s note – this fact should give you an appreciation of how somatostatin analogues tackle associated syndromes whilst giving you certain side effects as a result!)

Too much somatostatin may cause:

High blood sugar. This can cause headaches, frequent urination, dry skin and mouth, or feeling hungry, thirsty, tired, or weak.
Diarrhea.
Steatorrhea (very foul-smelling stool that floats).
Gallstones.
Yellowing of the skin and whites of the eyes.
Weight loss for no known reason.

Neuroendocrine Cancer Hormonal Syndromes – Clinical Esoterica

Awareness

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. The cancer can often be uncannily quiet, but the tumours can be 'functional' and over-secrete certain hormones to add or introduce symptoms which 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 generally feeling weak, fatigued, pain, agitated, anxious, dizzy, nauseous, acid reflux, skin irritation, anaemic, weight loss, weight gain, low blood sugar, high blood sugar, heart palpitations, headaches, sweating, high blood…

Diabetes – The NET Effect

Diet and Nutrition, Living with Neuroendocrine Cancer, Survivorship

My chest infection is now settled, as too is the excitement and apprehension behind my first ever Ga68 PET - the outcome of that is still a work in progress. Earlier this year, my thyroid 'lesion' on watch and wait was given a 'damping down' with the prescription of a thyroid hormone supplement but I await a re-ignition of that small bush fire downstream.Bubbling behind the scenes and clamoring for attention is the spiking of my blood glucose test results and I was very recently declared 'at risk' for diabetes One of my followers entitled a post in my group with "The hits keep coming" in reference to encountering yet another problem in the journey with Neuroendocrine Cancer. I now know how she feels, this issue is a bit of…

Weight – the NET Effect

Diet and Nutrition, Survivorship

Firstly, let me say that I have no intention of advising you how to lose or gain weight! Rather, I'd like to discuss what factors might be involved and why people with NETs might lose or gain weight either at diagnosis or after treatment. Clearly, I can talk freely about my own experience and associated weight issues. If nothing else, it might help some in thinking about what is causing their own weight issues.I once wrote a patient story for an organisation and the headline was "Did you mean to lose weight". Those were actually the words a nurse said to me after I nonchalantly told her I thought I'd lost some weight (....about half a stone). I answered the question with "no" and this response triggered a sequence of…

Neuroendocrine Cancer – tumour markers and hormone levels

Patient Advocacy

BackgroundI think most people 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 much higher levels in cancerous conditions. These substances can be found in the blood, urine, stool, tumour tissue,…

Neuroendocrine Cancer – the diarrhea jigsaw

Diet and Nutrition, Living with Neuroendocrine Cancer, Patient Advocacy, Survivorship, Treatment

Diarrhea can be a symptom of many conditions, but it is particularly key in Neuroendocrine Tumour (NET) Syndromes and types, in particular, Carcinoid Syndrome but also in those associated with various other NET types such as VIPoma, PPoma, Gastrinoma, Somatostatinoma, Medullary Thyroid Carcinoma.Secondly, it can be a key consequence (side effect) of the treatment for Neuroendocrine Tumours and Carcinomas, in particular following surgery where various bits of the gastrointestinal tract are excised to remove and/or debulk tumour load.There are other reasons that might be causing or contributing, including (but not limited to) endocrine problems such as hyperthryoidism, mastocytosis or Addison's disease (which may be secondary illnesses in those with NETs). It's also possible that 'non-sydromic' issues such as stress and diet are contributing. It could be caused by other things…

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…

Neuroendocrine Cancer – Horrible Hormones

Patient Advocacy

Hormonal imbalances are quite common in many conditions including day to day stuff. With Neuroendocrine Cancer, it can be a real challenge both at diagnostic and maintenance phases. In addition to the cancer angle, there's some strange stuff going on, inexplicable, frightening for the patient, an unwanted ingredient causing chaos!Until I was diagnosed with metastatic Neuroendocrine Cancer, I didn't have a clue about hormones - it's one of those things you just take for granted. However, hormones are vital to human health (male and female) and it's only when things go wrong you suddenly appreciate how important they are. Hormones are involved in many conditions, not just an issue with Neuroendocrine Tumours (NETs) but the presence of over-secreting hormones (often called peptides throughout) is useful to aid a diagnosis, albeit…
