Midgut carcinoid tumours are rare with an incidence of 0.5-2.1/100 000. The primary tumour is usually small and grows slowly but has almost always set metastases at diagnosis. When radically operated, most patients will eventually recur in their disease.

Neuroendocrine tumor; Micrograph of a neuroendocrine tumor. H&E stain: Specialty: Endocrine oncology : Neuroendocrine tumors (NETs) are neoplasms that arise from cells of the endocrine and nervous systems.They most commonly occur in the intestine, where they are often called carcinoid tumors, but they are also found in the pancreas, lung and the rest of the body. Midgut carcinoid tumors, which are considered the classic form of the disease, account for about 40%–50% of cases. They may arise from the distal duodenum, jejunum, ileum, appendix, or proximal colon, with a location in the appendix being the most common. Valid for Submission.

The transplantable human midgut carcinoid GOT1 was established as previously described (Kölby et al, 2001).In brief, cultured GOT1 cells were inoculated subcutaneously into nude mice. Midgut carcinoid tumors display CD4+ and CD8+ T cell infiltration, always in the presence of regulatory CD4+FoxP3+ cells. DISCUSSION: Midgut carcinoid patients display elevated T regulatory cell numbers and T cell dysfunction.

(thesis advisor) Carcinoid syndrome occurs in 20% to 30% of patients with midgut carcinoid tumours and approximately 5% of bronchial carcinoids. Other foregut tumours (e.g., pancreatic NETs) can cause carcinoid syndrome, although this is uncommon (1%). Hindgut tumours are generally non-functional and only occasionally cause carcinoid syndrome. Midgut carcinoids developing in the small intestine represent the most common cause of the carcinoid syndrome, with severe symptoms of flush, diarrhoea, and fibrotic valvular heart disease.
