Appendiceal carcinoid tumours: indications for right hemicolectomy and appendectomy

چکیده
Neuroendocrine tumours are a heterogonous group of tumours with a wide variety of clinical presentations. They arise from enterochromaffin cells located in neuroendocrine tissue throughout the body. Neuroendocrine tissue is derived from cells which migrated from the neural crest to the gastrointestinal endoderm. There are many types of NETs, phaeochromocytoma’s, small cell carcinoma’s of the lung and merkel cell carcinoma’s are just some examples. The focus of this review however lies with gastoenteropancreatic neuroendocrine tumours (GEPNETs), more specifically appendiceal carcinoid tumours (ACTs). GEP-NETs can be described as either functioning (hormone secreting) or non-functioning. 1
