For those who are still not sure what it's all about. This is a non-surgical treatment which is normally administered intravenously. It's based on the use of somatostatin receptors to attract a 'radiopeptide'. The radiopeptide is a combination of a somatostatin analogue and a radioactive material. As we already know, somatostatin analogues (i.e. Lanreotide/Octreotide) are a NET cell targeting drug using somatostatin receptors, so when combined with radioactivity, it binds with the NET cells and delivers a high dose of targeted radiation to the cancer while preserving healthy tissue in an attempt to reduce or kill tumours. In general, patients…

Somatostatin Receptors

Awareness, Treatment
Don't understand Somatostatin Receptors? Join the club! I got my head around the term 'Somatostatin' and 'Somatostatin Analogues' some time ago but the term 'Somatostatin Receptor' (SSTR) is still a bit of a mystery and it's come to the top of my list of things to study. SSTRs do come up in conversation quite often and I'm fed up of nodding sagely hoping it will eventually become clear! On analysis it looks like a technical subject - and therefore a challenge :-) I've taken a logical approach working from 'Somatostatin' to 'Somatostatin Analogue' before commencing on the 'receptor' bit. It is intentionally brief and (hopefully) simplistic! Somatostatin It's important to understand this hormone and then why your 'butt dart' is generically called a 'Somatostatin Analogue'. Some Neuroendocrine Tumours secrete hormones…

PRRT and the NHS England Cancer Drugs Fund

Treatment
[caption id="attachment_3922" align="aligncenter" width="425"] cost cutting vs life cutting?[/caption] As of 4 Nov 15, PRRT was delisted from the NHS England Cancer Drugs Fund. Appeals were made but were rejected, despite the glowing results from the NETTER-1 trial.  Although a replacement system is now in place, PRRT remains barred from routine NHS use. Please see the following post for the very latest on PRRT worldwide - CLICK HERE I was extremely disappointed to learn of the decision to remove PRRT (Lutetium or Yttrium) from the Cancer Drugs Fund (CDF) as reported by the NET Patient Foundation. You can read the detail of the decision here: CDF Statement.  PRRT has regularly been described by NET specialists and patients as the "magic bullet" due to its potential to shrink or kill tumours. This is the…
