A 54-year-old gentleman presented to his GP in July 2019 with significant weight loss, polyuria and nocturia for two to three months. His HbA1c was 78 mmol/mol. He was diagnosed with diabetes and started on Metformin 500 mg BD. Upon consultant review in September 2019, he reported a 26 kg weight loss over the preceding four years, much of which was apparently intentional, and right abdominal discomfort. His paternal grandmother died of pancreatic cancer, as did his paternal au...

Olfactory neuroblastoma (ONB) is a rare neuroendocrine tumour with a slow onset of symptoms, and classically a propensity for recurrence and a poor prognosis. Due to its rarity, there is no agreed standard therapy, but treatment will usually include surgical resection, adjuvant radiotherapy and/or chemotherapy. However, such tumours very often show positive uptake on somatostatin receptor radionuclide scanning, and selective use of peptide receptor radionuclide therapy (PRRT) ...

Background: The incidence of neuroendocrine neoplasms (NENs) in younger populations (<50 years) is increasing and was 1.8 per 100,000 persons in 2011. There is limited data on NENs and pregnancy.Methods: A retrospective analysis was performed on pregnant women with NENs managed in an ENETS Centre of Excellence. The objectives of the study were to describe the tumour characteristics, pregnancy outcomes, treatment and the tumour behaviour intra-pregnan...

Introduction: Phaeochromocytomas and paragangliomas (PPGL) are rare neuroendocrine tumours with no standardised protocol for treatment. 177Lu-DOTATATE peptide receptor radionuclide therapy (PRRT) is an emerging treatment option for patients with metastatic and/or inoperable PPGL, and with low toxicity. We present our experience with PRRT in advanced PPGL, treated in a ENETS Centre of Excellence.Materials and Methods: 165 patients with...

Introduction: NETs are a diverse group of neoplasms that originate from cells of the diffuse endocrine system. Often somatostatin analogues (SSA) are used as a first line treatment. Loose stools and steatorrhea are common adverse effects of SSA. This can affect the absorption of fat soluble vitamins and trace elements (TE). In this study we assess the prevalence of these deficiencies.Methods: A prospective study of 66 patients on SSA. Vitamins A,D,E,K an...

Introduction: Metastatic phaeochromocytomas (PCC) and paragangliomas (PGL), collectively known as metastatic PPGL (mPPGL), represent uncommon neuroendocrine tumours for which no standardized treatment guidelines exist. The emerging therapeutic modality employing 177Lu-DOTATATE Peptide Receptor Radionuclide Therapy (PRRT) has exhibited favourable tolerability in the management of these patients.Methods: In this...
