Theranostics - Ronny Allan - Living with Neuroendocrine Cancer

Tag: Theranostics

Theranostics is a term derived from a combination of the words therapeutics and diagnostics. In this emerging field of medicine, drugs and/or techniques are uniquely combined to simultaneously or sequentially diagnose and treat medical conditions.

The ability to acquire a diagnosis and administer therapy in one package is a game-changer for medicine as we know it. Not only does this offer the opportunity to save time and money, but it also potentially allows one to bypass some of the undesirable biological effects that may arise when these strategies are employed separately

SSTR PET – Ga68-DOTA-JR11 vs Ga68-DOTATATE

Clinical Trials and Research

Share on facebook Facebook Share on twitter Twitter Share on pinterest Pinterest Share on whatsapp WhatsApp Share on email Email Headline - 68Ga-DOTA-JR11 was found to detect significantly more liver lesions than 68Ga-DOTATATE; however, 68Ga-DOTATATE detected more bone lesions than 68Ga-DOTA-JR11.Although it had been in trial use for some years in Europe and elsewhere, the formal approval of 68Ga-DOTATATE has led to an increase in the development of other radionuclides, some in conjunction with therapeutic options (i.e. PRRT) making a 'theranostic' approach to diagnosing, treating and surveillance Neuroendocrine Cancer patients with somatostatin receptor positive tumours. I also wrote last year about another option called 64Cu, something already available in Europe, in particular Denmark.In another development which has been running for some time, a Ga68 variant called 68Ga-DOTA-JR11 has been in trial…

New Radiotracer Can Identify Nearly 30 Types of Cancer – SNMMI – 68Ga-FAPI PET/CT

Clinical Trials and Research, Living with Neuroendocrine Cancer

Updated 17th March 2023 When I wrote about this new PET in June 2019, it was for interest only, but I curiously noted the existence of "NET" in the list of 28 cancers. It is designed to compete with FDG PET. The study comes from a joint China/Singapore initiative. This update now confirms it could be more efficient than FDG for those types of cancer where FDG is the optimum imaging. Headline "A new radiotracer, 68Ga-FAP-2286, has been found to be more effective than the most commonly used nuclear medicine cancer imaging radiotracer, 18F-FDG. In a study published in the March issue of The Journal of Nuclear Medicine, 68Ga-FAP-2286 detected 100 percent of primary tumors across multiple cancer types as compared to 18F-FDG, which identified only 80 percent. 68Ga-FAP-2286 was also more effective in detecting lymph…

ASCO 2017 – Let’s talk about NETs #ASCO17

Clinical Trials and Research

ASCO (American Society of Clinical Oncology) is one of the biggest cancer conferences in the world normally bringing together more than 30,000 oncology professionals from around the world to discuss state-of-the-art treatment modalities, new therapies, and ongoing controversies in the field. As Neuroendorine Tumors is on a roll in terms of new treatments and continued research, we appear to be well represented with over 20 'extracts' submitted for review and display. This is fairly complex stuff but much of it will be familiar to many. I've filtered and extracted all the Neuroendocrine stuff into one list providing you with an easy to peruse table of contents, complete with relevant linkages if you need to read more. For many the extract title and conclusion will be sufficiently educational or at least…

All you need to know about Peptide Receptor Radionuclide Therapy (PRRT)

Clinical Trials and Research, Treatment

Short PRRT PrimerWhat is Peptide Receptor Radionuclide Therapy (PRRT)?What is PRRT? PRRT stands for Peptide Receptor Radionuclide Therapy, an FDA-approved therapy used for systemic treatment of neuroendocrine tumors. Peptide refers to the small molecule for this therapy. The Peptide used (DOTATATE or DOTATOC or DOTANOC) is very similar to Somatostatin, a hormone which binds to receptors found on neuroendocrine tumors. Receptor refers to a specific target on neuroendocrine tumor cells that the peptide attaches to. After the peptide joins with a Receptor, it becomes attached and enters the targeted tumor cell. Radionuclide refers to radioactive atom that is attached to the peptide. As the peptide enters the cell, it brings the Radionuclide into the tumor cell. The radionuclide (e.g. lutetium-177), then decays and emits radiation within the tumor cell.Therapy refers to the idea that we are using this combination of Peptides, Receptors, and Radionuclides…
