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.

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.

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.

Abstract There have been significant developments in diagnostic and therapeutic options for patients with neuroendocrine tumors (NETs). Key phase 3 studies include the CLARINET trial, which evaluated lanreotide in patients with nonfunctioning enteropancreatic NETs; the RADIANT-2 and RADIANT-4 studies, which evaluated everolimus in functioning and nonfunctioning NETs of the gastrointestinal
