The article gives a review of the literature concerning carcinoid tumours of the colon and rectum. Carcinoid tumours of the rectum are more common than of the colon, although these tumours are rarities. The carcinoid tumour grows slowly and the patients can survive for years with the disease. Treatment of the rectal carcinoid depends on the size and invasiveness of the primary tumour, as a non-invasive tumour less than 2 cm in diameter can be locally excised. For carcinoids of the colon, the treatment of tumours of less than 2 cm and without invasion will be local excision. For larger and/or invasive tumours in both colon and rectum the treatment is resection. The prognosis for colonic carcinoids is worse than for rectal carcinoids. Adjuvant treatment forms are briefly described. Follow-up programmes for these patients are generally long (over five years) and include recto-/colonoscopy, and search for metastatic spread.
