Introduction: Some functional neuroendocrine tumours (NETs) secrete serotonin, leading to the symptoms of carcinoid syndrome (e.g. diarrhoea and flushing). In this condition, increased urinary concentrations of the serotonin metabolite 5-hydroxyindoleacetic acid (5-HIAA) are often detected. Measurement of 24-hour urinary 5-HIAA is therefore used to investigate patients with confirmed or suspected carcinoid syndrome. We sought to evaluate the appropriateness and effectiveness o...

Introduction: In the UK, the fasting plasma concentrations of a panel of gut hormones (vasoactive intestinal peptide (VIP), gastrin, pancreatic polypeptide, glucagon and somatostatin as well as chromogranin A) are frequently measured during the evaluation of patients who have confirmed or clinically suspected neuroendocrine tumours (NETs). However, elevated concentrations of these hormones are sometimes also detected in patients who have no other evidence of a NET. We sought t...

Background: People who have autoimmune atrophic gastritis commonly develop type 1 gNETs, but are also at increased risk of developing gastric adenocarcinoma. Type I gNET patients usually have multiple gastric polyps and have an excellent prognosis when the polyps measure.Method: Retrospective audit of type I gNET patients managed within Liverpool ENETS Centre of Excellence 2004–2018.Results: 86 patients (median age 67 years, 5...

Background: New nuclear medicine imaging techniques have improved diagnosis, staging and treatment planning for BC. 68Ga-DOTA PET is preferable to standard somatostatin receptor scintigraphy where available (ENETS guidelines); however, its role in the management of BC remains unclear.Methods: All consecutive patients diagnosed with BC from two ENETS Centres of Excellence were identified retrospectively; patients with high grade tumours or lack...

Background: Pancreatic neuroendocrine tumours (panNETs) are rare tumours (prevalence 4/100,000). Diagnosis and staging of panNETs requires biochemical screening, cross-sectional imaging (with CT/MRI), endoscopic ultrasound (EUS) and where available, functional imaging using 68Ga-labelled synthetic octreotide analogues using PET-CT due to its reported higher sensitivity and specificity.Methods: A retrospective, electronic case note study was ca...
