Introduction: Carcinoid crisis is a life threatening endocrine emergency. It remains unclear whether there is an optimal dose of prophylactic somatostatin analogue (SSA) therapy in the peri-operative periodCase Study: A 62 year old lady with a new diagnosis of metastatic carcinoid disease was electively admitted for a right hemicolectomy for a well differentiated neuroendocrine tumour in the terminal ileum. A multi-disciplinary decision was made to offer...

Introduction: It is established practice to localise parathyroid lesions preoperatively using ultrasound (US) and sestaMIBI (MIBI). Whilst these imaging techniques have good sensitivity/specify, there are patients in which imaging does not localise a parathyroid lesion. 11C-Methionine PET (MET PET) is an imaging modality where 11C-methionine, a radioactive tracer, is taken up at sites of protein/peptide synthesis and has been demonstrated to be effective ...

Peptide receptor radionuclide therapy (PRRT) is a targeted therapy using synthetic somatostatin analogues attached to a radionuclide, which binds to tumours expressing somatostatin receptors. The aim was to review the role of PRRT in a tertiary referral centre. We retrospectively reviewed a cohort of 25 patients (eight males, 17 females), with a median age of 65, who received Yttrium-90 DOTATATE or Lutetium-177 DOTATATE at Addenbrookes Hospital. The location of the primary tum...

Although adrenal vein sampling (AVS) remains the gold-standard for distinguishing unilateral and bilateral disease in primary hyperaldosteronism (PHA), it is technically demanding and not always feasible. Metomidate (MTO), a potent inhibitor of CYP11B1 and CYP11B2, can be C11H3-labelled as a PET tracer (11C-MTO), and we have previously shown it to be an alternative to AVS for localising unilateral aldosterone-producing adenomas (APAs) (Burton <...

Background: Adrenal vein sampling (AVS) remains the gold-standard for distinguishing unilateral and bilateral disease in primary aldosteronism (PA). However, it is invasive, technically demanding, and may yield inconclusive or equivocal results. 11C-Metomidate PET-CT (11C-MTO-PET-CT) is a non-invasive alternative to AVS for localising unilateral aldosterone-producing adenomas (APAs).Methods/patients: We report a retrospective analys...

Aim: To review the presentation, management and outcomes in adult patients with MEN1 attending a multidisciplinary clinic.Methods: Case notes and electronic records were reviewed in patients attending a tertiary centre clinic for care of MEN1.Results: Forty-eight patients were analysed; 46% were male and 54% female. Mean age was 49 years (range 14–89) and 4% were deceased. Eighty-five percent had confirmed MEN1 mutations and 2...
