Overview
Rectal neuroendocrine tumours (carcinoids) belong to the hindgut carcinoid group, according to older classification. They are not associated with carcinoid syndrome. Colonoscopy is a gold standard for detecting rectal carcinoids. Endosonography is important for assessing rectal carcinoid growth. CT colonography and 111In-octreotide scanning is required for staging if residual or metastatic disease is suspected. Serum chromogranin A and acid phosphatase are necessary biochemical markers. Local resection is sufficient for small tumours, anterior resection for rectal tumours > 2cm is appropriate. There is no evidence base for adjuvant therapy. Patients with rectal carcinoids < 2cm have a very good prognosis with long term survival.
Key words:
carcinoid – rectal cancer – chromogranin A – OctreoScan – endosonography – therapy
