Gastrointestinal Neuroendocrine Tumours

Neuroendocrine tumours (NETs) develop from enterochromaffin cells, which are located throughout the gastrointestinal tract. Most NETs arise in the gastro-entero-pancreatic tract (GEP-NETs) and they are increasingly found during endoscopic investigation. Although rare, the incidence of NETs is increasing, and prolonged patient survival means that their prevalence is high. Prognosis and treatment options vary according to the size, grade/stage and functionality of the NET, making correct diagnosis and staging key.

In this online course, Dalvinder Mandair, Christos Toumpanakis and Martyn Caplin cover all aspects of gastric NETs, duodenal NETs and rectal NETs—their pathogenesis, investigation, diagnosis, classification, staging, management and prognosis.  

The course includes comprehensive PPT slides and bespoke video presentations, which were filmed with Dalvinder Mandair in London in July 2019. The combined material has a total duration of approximately 50 minutes. The estimated time needed to complete the course, including the final assessment, is 60 minutes.

This course was developed by: UEG.

  • To develop an understanding of the classification of gastric, duodenal and rectal neuroendocrine tumours (NETs)
  • To recognise the endoscopic features that may indicate the presence of a NET
  • To learn which investigations are required as part of the diagnostic work-up
  • To identify the patients that need to be referred to a specialist NET centre
