Colonic Carcinoids

Current Clinical Trials

Colonic carcinoids are often exophytic and large (>5 cm), but they rarely bleed. Only occasional right-sided lesions are positive with 111-Indium octreotide scintigraphy. Many of these tumors are aggressive with a high proliferation rate, and they often present with more liver metastases than regional lymph node metastases.[1] These tumors of the colon are treated similarly to adenocarcinoma of the colon.[2] Attempts to achieve radical resection by hemicolectomy or subtotal colectomy with lymphadenectomy should be made, but frequently only debulking is possible. The overall 5-year survival rate is approximately 40% and is slightly worse than the survival rate for colon adenocarcinoma.[1]

Current Clinical Trials

Check for U.S. clinical trials from NCI's list of cancer clinical trials that are now accepting patients with localized gastrointestinal carcinoid tumor and regional gastrointestinal carcinoid tumor. The list of clinical trials can be further narrowed by location, drug, intervention, and other criteria.

General information about clinical trials is also available from the NCI Web site.
