Indium 111-pentetreotide - Ronny Allan - Living with Neuroendocrine Cancer

Tag: Indium 111-pentetreotide

A radioactive drug used to find certain types of neuroendocrine tumors (tumors that form from cells that release hormones). Indium In 111-pentetreotide binds to a protein called somatostatin receptor, which is found on some neuroendocrine tumor cells. Indium In 111-pentetreotide builds up in these cells and gives off radiation that can be detected by a scanner to help show where the tumor cells are in the body.

Neuroendocrine Tumours – now you see them, now you don’t!

Treatment

In my post entitled "If you can see it, you can detect it", I listed the different types of scanning techniques and technology to find evidence of disease in Neuroendocrine Tumours (NETs). Of course, while scans, blood and (current) marker tests can give some pretty big and important clues, "tissue is the issue" to determine type.Even after formal diagnosis, seeing all the tumours can be a challenge with NETs. In the article I quoted above, I indicated that scans for NETs can be analogous to picking 'horses for courses'. For example, most NETs have somatostatin receptors and can often be seen better on functional scans e.g. somatostatin receptor scintigraphy (SRS) or somatostatin receptor PET (SSTR-PET), combined with the use of radionuclides designed specifically for this purpose e.g. In 111, Tc99m,…

Detectnet™ (64Cu-DOTATATE) – an expansion of the Somatostatin Receptor PET Imaging for Neuroendocrine Cancer

Clinical Trials and Research, Living with Neuroendocrine Cancer, Treatment

Edit 21st January 2021. The imaging time window of 64Cu-DOTATATE positron emission tomography/computed tomography (PET/CT) for patients with neuroendocrine neoplasms can be expanded from one hour to three hours post-injection, according to new research published in the January 2021 issue of The Journal of Nuclear Medicine. Read more here Edit 4th September 2020. 64Cu-dotatate now named Detectnet™ is approved for use by US FDA. Majority read revealed Detectnet had over 98% accuracy, 100% sensitivity, and over 96% specificity to confirm or exclude presence of disease. Read more here. Edit 14th July 2020. Expanded Access Program via clinical trial now recruiting - see below. The objective of this trial is to provide patients with confirmed or suspicion of NET access to Copper Cu 64 Dotatate for the detection, localization, and monitoring of…

Theranostics for Neuroendocrine Cancer – A Find and Destroy Mission

Awareness, Clinical Trials and Research, Living with Neuroendocrine Cancer, Treatment

[caption id="attachment_14426" width="1200"] Courtesy of Pashtoon Kasi MD on Twitter https://twitter.com/pashtoonkasi/status/1078675398601396224[/caption] Theranostics is a joining of the words therapeutics and diagnostics. You may also see it conveyed as 'Theragnostics' and these terms are interchangeable. The basic aim of theranotistics is to find and then destroy the 'bad guys'. With Neuroendocrine Cancer, finding the tumours (the bad guys) can often be a challenge - they can be small and/or difficult to find - they are sometimes expert at camouflage. Moreover, once found, they can then be difficult to treat (destroy), as they can often prove resistant to conventional cancer drugs and many are inoperable due to sheer quantity, spread and positioning. When they are found and identified, it's also really helpful to know from the intelligence gathered, how successful the destroy…
