Gastrointestinal Carcinoid Tumors Treatment (PDQ®): Treatment - Health Professional Information [NCI] - Duodenal Carcinoids

continued...

Regardless of the size of the primary tumor, abnormal lymph nodes detected on pretreatment imaging studies or at the time of surgery should be resected. Because little is known about the natural history of unresected, grossly evident lymph node metastases, nonoperative management might otherwise be supported. Node-positive patients should undergo continued radiographic surveillance regardless of the size of the primary tumor.[1]

Ampullary and periampullary duodenal carcinoids deserve special consideration because they differ clinically, histologically, and immunohistochemically from carcinoid tumors that occur elsewhere in the duodenum.[5] Although their rarity precludes the establishment of any definitive natural history, these tumors appear to behave unpredictably and might be viewed as a distinct category of carcinoid tumor when treatment options are being considered.[2] Compared with tumors in other duodenal sites, even small (<1 cm) ampullary and periampullary carcinoid tumors exhibit distinctly different aggressive behavior, and they may metastasize early.[5,6]

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.
