    Abstract:
    BACKGROUND: Extra-appendiceal colonic carcinoids are uncommon neuroendocrine tumors with a poor prognosis compared with carcinoids of other gastrointestinal origins. Few studies have examined the clinicopathologic profile and behavior of this rare tumor. MATERIALS AND METHODS: A retrospective analysis was performed on patients with colonic carcinoid tumors evaluated at a single tertiary care center between 1996 and 2012. Collected data included patient and tumor characteristics, presentation, treatment, recurrence, and survival. Results were integrated into a comprehensive review of the colonic carcinoid literature. RESULTS: In total, 114 patients with colorectal carcinoid tumors were identified, and 15 patients with extra-appendiceal tumors were analyzed. The mean age was 58.6 ± 3.0 y, and subjects were predominantly male (73.3%). The most common presenting problem was abdominal pain (33.3%), although 26.7% of patients were asymptomatic. Cecal tumors were the most prevalent (73.3%), and most patients underwent right hemicolectomy. Three patients with lesions < 1 cm were treated endoscopically. The mean tumor diameter was 2.9 ± 0.5 cm, with lymph node or distant metastasis present in 53.3% and 26.7%, respectively. All but two patients underwent a presumed curative resection. During a mean follow-up of 4.2 ± 1.0 y, there was only one death (non-carcinoid specific). Eleven patients were alive without evidence of disease at last follow-up and three patients were alive with disease, one of whom initially had a presumed curative resection that recurred. CONCLUSIONS: This case series further elucidates the clinicopathologic characteristics of colonic carcinoid tumors, which aids physicians in guiding the diagnosis and management of these rare tumors.
