MP0712 (212Pb x DLL3), Radio-DARPin – DLL3 Radioligand Therapy Trial for Neuroendocrine Neoplasms
What is Radioligand Therapy? When you browse the internet, you may see the term "Radioligand Therapy (RLT)" and wondered what it was. There's a simple explanation to what it is; and why you may be seeing more of it. Firstly, you will all be aware of Peptide Receptor Radionuclide Therapy (PRRT), right? Well that is just a type of RLT where the target is somatostatin receptors (SSTR). RLTs can have different targets. You may be seeing the term Radioligand Therapy more because this technology is starting to be used on other cancers but almost always different target routes. The obvious…
Understanding your Somatostatin Receptor (SSTR) PET/CT Scan Results
BackgroundIn my online patient group, there is constant discussion about the meaning of both pictures and words on scan reports. The one that seems to cause the most confusion is PET scans, mainly somatostatin receptor (SSTR) PETs such as Ga68 and Cu64 variants. Worth adding that it's the addition of a nuclear tracer that makes PETs seem different. Generally speaking, the PET hardware is essentially the same. Most have a built-in CT scan, much less frequently an MRI scan.Confusion is often triggered by healthcare system processes where the patient receives the report before the appointment to discuss the results with…
Prospective Phase II Trial of Prognostication by 68Ga-NOTA-AE105 uPAR PET in Patients with Neuroendocrine Neoplasms: Implications for uPAR-Targeted Therapy
Summary A novel PET radiotracer can accurately assess the presence of a biomarker that indicates the level of tumor aggressiveness in neuroendocrine neoplasms (NENs). According to research published in the September issue of The Journal of Nuclear Medicine, the detection of the biomarker provides useful information for physicians to provide personalized care for patients with NENs and may also serve as a potential target for peptide radionuclide therapy (PRRT) for NEN patients.What is uPAR? Tumorigenesis (the production or formation of a tumour or tumours) is closely related to the loss of control of many genes. Urokinase-type plasminogen activator receptor (uPAR), a glycolipid-anchored…
New PET findings after COVID-19 vaccination: Keep Calm and Carry On?
After a few months of introducing C-19 vaccines, many cases of false-positive lymph nodes were reported on nuclear PET scans, some of which led to unnecessary biopsies and unnecessary worry for the patients concerned. According to Mayo Clinic, the positive nodes were on the same side as the vaccine shot in the cases where the injection site was known. Mayo added that some cases had uptake in the deltoid muscle, which is normally where vaccine injections are given, leading to increased suspicion of false positive in cases where uptake was in both deltoid muscle and axillary lymph nodes (armpit). At…
