Carcinoider kan också förekomma i ändtarmen, tjocktarmen, blindtarmen samt i magsäcken. Beroende på var i tarmsystemet de sitter kallas de foregut, midgut och hindgut. Allra vanligast är att primärtumören finns i midgut, det vill säga i tunntarmen eller blindtarmen. – Varje år upptäcks mellan 60 och 100 nya fall i Sverige.

2003 ). The differences cannot be explained by whether the NET is situated in the foregut, midgut, or hindgut. 1, 4 Appendiceal NET is known to be less prone to metastasis. 1, 3 This may be due to the high rate of incidental findings during appendectomies, or because the appendix is an immunological organ where malignant cells can therefore be expected to be frequently recognized by the immune system. and urinary Indoles in carcinoid and islet cell tumor patients Chapter 5 Abdominal angina in patients with a midgut carcinoid, a sign 77 of severe pathology. World J Surg. 2005;29:1139-42.

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. The tumours may be histologically identified with specific chromogranin A or synaptophysine immunostainings, and by serotonin reactivity, which supports a midgut origin. Ten per cent (10%) or less of carcinoids, primarily some midgut carcinoids, secrete excessive levels of a range of hormones, most notably serotonin (5-HT) or substance P, causing a constellation of symptoms called carcinoid syndrome: flushing; diarrhea; asthma or wheezing; congestive heart failure (CHF) abdominal cramping; peripheral edema Midgut carcinoids are typically argentaffin positive, have a higher incidence of deletions in chromosome 18, and tend to produce bioamines such as serotonin and bradykinin ( 2, 3, 7 – 12 ). Currently, very few models are available to study NETs, and still fewer are specific to carcinoid tumors. CANCER Circulating markers of prognosis and response to treatment in patients with midgut carcinoid tumours G B Turner, B T Johnston, D R McCance, A McGinty, R G P Watson, C C Patterson, CANCERFORMER Neuroendokrina tumörer, NET. Neuroendokrina tumörer är cancertumörer som kan finnas i mag-tarmkanalen eller i lungorna. Många som får en neuroendokrin tumör blir av med den, eller kan leva ett bra liv länge trots sjukdomen. Classical midgut carcinoids arise from the entero-chromaffin cells in the ileum, cecum, and ascending colon.

Active surgical and medical therapy of the tumour disease reduced the hormonal secretion and, combined with cardiological surveillance, made right ventricular heart failure a rare cause of death in these patients. Tricuspid valvular disease is a common manifestation of the midgut carcinoid syndrome and advanced changes are associated with poor long‐term survival. Active surgical and medical therapy of the tumour disease reduced the hormonal secretion and, combined with cardiological surveillance, made right ventricular heart failure a rare cause of death in these patients. © 2001 British Journal of Surgery Society Ltd 2021-03-24 · Midgut carcinoids originating in the small intestine are the most common cause of the carcinoid syndrome. These tumours typically progress slowly and have an extended disease course, and although they often present with metastases at diagnosis, surgical treatment has become increasingly important for their management. Midgut carcinoid tumours were considered as the group of tumours identified by histopathology to be classical carcinoid tumours with positive neuroendocrine markers and histology consisting of the typical characteristic rounded nests of closely packed cells with peripheral palisades.
