Tag: Gastrin pH

pH is the measurement of the acidity or alkalinity of a solution, or a negative logarithmic scale of hydrogen ion concentration in a solution.

Normal gastric juices are acidic in nature, having a pH of approximately 1-3. Hydrochloric acid is secreted by gastric parietal cells to kill or reduce the growth of certain bacteria and to facilitate the denaturation of proteins as they enter the gastro-intestinal tract.

The measurement of Gastrin ph can sometimes help to distinguish between Type I and Type II but is not 100% sensitive.

A spotlight on Gastric Neuroendocrine Neoplasms

A spotlight on NENs - Types, Awareness, Patient Advocacy, Spotlight on NENs - Types Series, Treatment

What are Gastric NENsUnlike other anatomical types, the word Gastric is used to indicate a tumour (NET) or carcinoma (NEC) in the stomach. The stomach lies at the bottom of your oesophagus and connects to the first part of the small intestine (the duodenum). Clearly a key part of the gastrointestinal system, it processes food on its journey downwards.The stomach produces strong acid. This kills many microorganisms that might have been swallowed along with the food. It also contains special chemicals called enzymes. These are important for breaking down the food so it can be absorbed by the body. After it leaves the stomach, the partially digested food passed into the intestines where it begins to be absorbed.The main parts of the stomach are shown below (often this can give…

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,…

Summary May produced the best statistics in 2023, mainly due to your support for my blog post on Maria Menounos whose announcement headlined as “Pancreatic Cancer” caused a storm within the Neuroendocrine Cancer community. Below, I’ll list the top performing blog posts in May and no secret which one is listed first. Repeat after me: […]

Getting back in the saddle

Those who follow my Facebook page Ronny Allan may remember my cycling faux pas in April causing me to bruise or fracture a rib (here if you missed it). I was told it may take up to 6 weeks to heal, it took 5. During that painful period, I looked ahead and wondered how I […]

Clinical Trial: Phase 1/2a Study of 23ME-00610 in Patients With Advanced Solid Malignancies (incl Neuroendocrine Neoplasms)

Who are 23andMe? I personally had not heard of 23andMe but many people in North America might have. When you first look at what they do, you can be excused for thinking they are just another ‘Ancestry’ company, but they are more than that. They also get involved in genetics and health. To quote their […]

A spotlight on Chromogranin A

What is Chromogranin A? Chromogranin A (CgA) is an acidic protein released along with catecholamines from chromaffin cells and nerve terminals. This statement alone might explain why it’s a good marker to use with Neuroendocrine Neoplasms. It is said to be a measure of tumour bulk. Depending on the test kit being used, you may […]

Neuroendocrine Cancer: Catch them early, not late!

Diagnosing Neuroendocrine Neoplasms (NENs). It’s no secret that Neuroendocrine Neoplasms (NENs) can be difficult to diagnose, particularly well differentiated slow growing types (NETs) which can sometimes be difficult to see. Plus, many patients present with relatively routine day to day symptoms suggesting a myriad of day-to-day illnesses seen daily in every GP/PCP practice. But conversely, […]
