Surgical treatment of neuroendocrine tumours of the pancreas

Gastro-entero-pancreatic (GEP) endocrine tumours can originate from various pancreatic islet cells, from endocrine cells of the gastric and duodenal mucosa, or from APUD cells of neuroectodermal origin in the gastrointestinal tract. They are benign when smaller than 2 cm, but larger tumours are generally malignant. Surgery is the only method for the curative treatment of GEP tumours. A diagnosed and localised tumour is an absolute indication for radical surgery. Conservative medical treatment may be indicated only in an inoperable condition, but in this case tumour reduction surgery is suggested. In the last 15 years 22 patients with pancreatic neuroendocrine tumours were treated without any mortality. Except for two of them, the surgical therapy was curative.
