Background The diagnosis of neuroendocrine neoplasms (NENs) is often delayed. This first UK population-based epidemiological study of NENs compares outcomes with non-NENs to identify any inequalities. Methods Age-standardised incidence rate (ASR), 1-year overall survival, hazard ratios and standardised mortality rates (SMRs) were calculated for all malignant NENs diagnosed 2013–2015 from UK national Public Health records. Comparison with non-NENs assessed 1-year overall survival (1YS) and association between diagnosis at stage IV and morphology. Results A total of 15,222 NENs were identified, with an ASR (2013–2015 combined) of 8.6 per 100,000 (95% CI 8.5–8.7); 4.6 per 100 000 (95% CI, 4.5–4.7) for gastro-entero-pancreatic (GEP) NENs. The 1YS was 75% (95% CI, 73.9–75.4) varying significantly by sex. Site and morphology were prognostic. NENs (predominantly small cell carcinomas) in the oesophagus, bladder, prostate, and female reproductive organs had a poorer outcome and were three times more likely to be diagnosed at stage IV than non-NENs. Conclusion Advanced stage at diagnosis with significantly poorer outcomes of some NENs compared with non-NENs at the same anatomical site, highlight the need for improved access to specialist services and targeted service improvement.

BackgroundNeuroendocrine tumours are uncommon tumours; there is often a long period between the onset of symptoms and diagnosis. This study aims to address the symptoms prior to diagnosis of people with known neuroendocrine tumours and also the involvement of healthcare providers prior to the diagnosis.MethodsA web based survey was designed to cover two broad areas of patient symptoms and healthcare interactions prior to diagnosis. This was tested and adapted by patient and clinician input prior to distribution via Survey Monkey.ResultsThe results demonstrated a median time from first symptom to diagnosis of 53.8 months. The most frequent initial symptoms were of pain, change in bowel habit and fatigue. 31% of respondents noted weight loss prior to diagnosis. 80% of respondents visited their GP regarding the symptoms a median of 11 times. 58% of respondents were referred to secondary care where they were seen a median 3 times. 30% presented acutely to A&E and this led to their diagnosis.ConclusionIn conclusion, there is a long time from onset of symptoms to diagnosis in all types of NETs. This is despite many respondents having alarm symptoms at diagnosis. Further education and awareness regarding malignancy may help with earlier diagnosis.

SUMMARYBackground: Somatostatin analogues are the best therapy for controlling the symptoms of malignant carcinoid syndrome. Octreotide acetate given as subcutaneous injection up to three times daily, intramuscular Lanreotide injection given once per 1-2 weeks and monthly intramuscular Sandostatin LAR have demonstrated similar efficacy in short-term studies. Aim: To assess the long-term effect of Sandostatin LAR on the management of patients with malignant carcinoid syndrome. Methods: This was a 3-year retrospective study. Twenty-seven patients were assessed with a median follow-up of 23 months. Thirteen patients were switched from subcutaneous octreotide and 14 patients
