Neuroendocrine Cancer: Somatostatin Receptor (e.g. Ga68, Cu64) PET Scans – a game changer?
I was diagnosed in 2010 with metastatic NETs clearly showing on CT scan, the staging was confirmed via an Octreotide Scan which in addition pointed out two further deposits above the diaphragm (one of which has since been dealt with). In addition to routine surveillance via CT scan, I had two further Octreotide Scans in 2011 and 2013 following 3 surgeries, these confirmed the surveillance CT findings of the remnant disease. The third scan in 2013 highlighted an additional lesion in my thyroid (still under a watch and wait regime, biopsy inconclusive - but read on....). In 2018, my 6…
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…
Incidentally, it’s not NET! SSTR PET e.g. Ga68/Cu64)
Incidental Findings in SSTR PET Somatostatin Receptor (SSTR) PET scans (e.g. Ga68/Cu64) have transformed the imaging landscape for Neuroendocrine Cancer, mainly for well-differentiated NETs, most of which will be somatostatin receptor positive. However, Oncologists/NET Specialists and radiologists must be aware of the various physiologic and other pathologic processes in which cellular expression of SSTR can result in interpretative error. Included in these pitfalls are incidental findings. What is an incidental finding? An incidental finding, also known as an incidentaloma, may be defined as “an incidentally discovered mass or lesion, detected by CT, MRI, or other imaging modality (e.g. PET) performed…
Detectnet™ (64Cu-DOTATATE) – an expansion of the Somatostatin Receptor PET Imaging for Neuroendocrine Cancer
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 -…
All you need to know about Somatostatin Receptor PET/CT Scans for Neuroendocrine Tumours
Cancer is a growth industry ...literally! More people are being diagnosed than ever before. Fortunately, more people are surviving than ever before. This is against a backdrop of better awareness, better screening in the big population cancers, and to a certain extent better diagnostic tools, all of which is leading to earlier diagnosis. So how does this affect Neuroendocrine Cancer? According to the latest SEER database figures for Neuroendocrine Cancer, one reason for the 7 fold increase in incidence rates since the 1970s is all of those things above including better diagnostics. This has led to a revised set of…
