Abstract
Regional lymphadenectomy is recommended for all colon carcinoids whereas resection without lymphadenectomy is accepted for selected appendiceal and rectal carcinoids We examined the relation of tumor size and depth to lymph node metastasis in order to determine whether colon carcinoids could be selected for endoscopic resectionWe identified 929 patients who underwent resection of localized colon carcinoids without distant metastasis diagnosed from 1973 to 2006 The diagnosis of small and superficial tumors increased over time p 0001 The presence of lymph node metastasis was adversely associated with survival p 0001 however there was only a trend toward independence on multivariate analysis p = 0054 Tumor size and depth were associated with lymph node metastasis p 0001 p 0001 Tumors were subgrouped by size and depth to find cases with a low risk of lymph node metastasis Intramucosal tumors 1 cm had a 4 rate of lymph node metastasis while all other subgroups had rates ≥14
