Tag: Neurokinin A (NKA)

Neurokinin A (formally known as substance K) is a member of the tachykinin family of neuropeptide neurotransmitters. Tachykinins are important contributors to nociceptive processing, satiety, and smooth muscle contraction. Tachykinins are known to be highly excitatory neurotransmitters in major central neural systems.

Sometimes offered as an additional test for NET patients in USA.

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…

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…

I don’t tend to share some very personal stuff, but this is on the boundary of that rule and there are some important messages to be teased out. For those who follow my blog in detail, you may remember the post entitled “Neuroendocrine Cancer – Signs, Suspicions, Symptoms, Syndromes, Side-Effects, Secondary Illnesses, Comorbidities, and Coincidences” […]

First and only FDA-cleared, fully automated chromogranin A assay

There has been controversy about the utility of Chromogranin A for many years now. Specialists have been critical about its use but to be fair even those less critical still confirm that alone it would not be trusted to formally diagnose Neuroendocrine Cancer. That said, it was still controversial when certain US guidelines were updated […]

Neuroendocrine Cancer: Question, Clarify, Confirm

One of the many observations I make in my private Neuroendocrine Cancer Facebook group is the misunderstandings caused by the use of non-standard terminology combined with a lack of understanding of what is up to date or not. And I don’t always mean a misunderstanding by patients. If I am to believe doctors uttered some […]

Lanreotide: Ipsen injection devices vs generic injection devices

Whenever I get a chance to talk to a pharma involved in somatostatin analogue injection devices, I tell them one very important thing …… “To the patient, the injection delivery is almost as important as the drug”. I also add that my opinion is based on thousands of comments about the patient experience in my […]
