A spotlight on Chromogranin A

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 also see test results for Chromogranin B (CgB) alongside CgA. CgB is said to be less affected by false positives and forms a useful adjunct to the more established chromogranin A measurement.  The brand of test kit which includes CgB tends to be confined to…

Neuroendocrine Cancer: Follow up tests and checks

Neuroendocrine Cancer: Follow up tests and checks

Since 2010 I’ve had a lot of surveillance and testing. More than ordinary people can imagine. I can see from various comments on my public pages and posts within my private group, that some people get a lot more than I do and some get less. It’s not true to say we all get the same, there are many factors including stage, grade, type of Neuroendocrine Neoplasm, healthcare system, miscellaneous problems, therapy, and even age.I have metastatic small intestine NET.  In the first year or two after diagnosis, I seemed to be in an almost continuous testing phase but that…
Selecting patients and the Challenges of Evaluating Response to PRRT in GEPNETs: The Present and the Future

Selecting patients and the Challenges of Evaluating Response to PRRT in GEPNETs: The Present and the Future

Share on facebook Facebook Share on twitter Twitter Share on pinterest Pinterest Share on whatsapp WhatsApp Share on email Email Fascinating article from the Italian NET scientific community.  This article is more than just what the title says, it provides overviews on many facets of NETs including markers, scans and PRRT itself. It covers how to select patients for PRRT in the first place, i.e. who is most likely to get a good response to this treatment and then look at how to track and assess that response. The important thing I gathered from reading is that none of this…

Neuroendocrine Cancer – surveillance and follow up

Since 2010 I've had a lot of surveillance and testing. More than people can imagine. I can see from various comments on my public pages and posts within my private group, that some people get a lot more than me and I get more than others. It's not true to say we all get the same, there are many factors including stage, grade, type of Neuroendocrine Neoplasm, healthcare system/guidelines, miscellaneous problems, therapy, and even age.In the first year or two after diagnosis, I seemed to be in a continuous testing phase but that was mainly due to seeing so many…
