This information is produced and provided by the National Cancer Institute (NCI). The information in this topic may have changed since it was written. For the most current information, contact the National Cancer Institute via the Internet web site at http://cancer.gov or call 1-800-4-CANCER.
Incidence and Mortality
Estimated new cases and deaths from small intestine cancer in the United States in 2017:
Adenocarcinoma, lymphoma, sarcoma, and carcinoid tumors account for the majority of small intestine malignancies, which, as a whole, account for only 1% to 2% of all gastrointestinal malignancies.[2,3,4,5]
Follow-up and Survivorship
As in other gastrointestinal malignancies, the predominant modality of treatment is surgery when resection is possible, and cure relates to the ability to completely resect the cancer. The overall 5-year survival rate for resectable adenocarcinoma is only 20%. The 5-year survival rate for resectable leiomyosarcoma, the most common primary sarcoma of the small intestine, is approximately 50%.
Carcinoid tumors of the small intestine are covered elsewhere as a separate cancer entity. (Refer to the PDQ summary on Gastrointestinal Carcinoid Tumor Treatment for more information.)
Tumors that occur in the small intestine include the following:
Approximately 25% to 50% of the primary malignant tumors in the small intestine are adenocarcinomas, and most occur in the duodenum. Small intestine carcinomas may occur synchronously or metachronously at multiple sites.
Leiomyosarcomas occur most often in the ileum.
Some 20% of malignant lesions of the small intestine are carcinoid tumors, which occur more frequently in the ileum than in the duodenum or jejunum and may be multiple.
It is uncommon to find malignant lymphoma as a solitary small intestine lesion.
The treatment sections of this summary are organized according to histopathologic type rather than stage.
Definitions of TNM
The American Joint Committee on Cancer (AJCC) has designated staging by TNM classification to define small intestine cancer.
Standard treatment options:
Treatment options under clinical evaluation:
Current Clinical Trials
Check the list of NCI-supported cancer clinical trials that are now accepting patients with small intestine adenocarcinoma. 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 website.
Treatment options under clinical evaluation:
Check the list of NCI-supported cancer clinical trials that are now accepting patients with small intestine leiomyosarcoma. The list of clinical trials can be further narrowed by location, drug, intervention, and other criteria.
Check the list of NCI-supported cancer clinical trials that are now accepting patients with recurrent small intestine cancer. The list of clinical trials can be further narrowed by location, drug, intervention, and other criteria.
The PDQ cancer information summaries are reviewed regularly and updated as new information becomes available. This section describes the latest changes made to this summary as of the date above.

Purpose of This Summary
This PDQ cancer information summary for health professionals provides comprehensive, peer-reviewed, evidence-based information about the treatment of small intestine cancer. It is intended as a resource to inform and assist clinicians who care for cancer patients. It does not provide formal guidelines or recommendations for making health care decisions.
Reviewers and Updates
This summary is reviewed regularly and updated as necessary by the PDQ Adult Treatment Editorial Board, which is editorially independent of the National Cancer Institute (NCI). The summary reflects an independent review of the literature and does not represent a policy statement of NCI or the National Institutes of Health (NIH).
Board members review recently published articles each month to determine whether an article should:
Changes to the summaries are made through a consensus process in which Board members evaluate the strength of the evidence in the published articles and determine how the article should be included in the summary.
The lead reviewer for Small Intestine Cancer Treatment is:
Any comments or questions about the summary content should be submitted to Cancer.gov through the NCI website's Email Us. Do not contact the individual Board Members with questions or comments about the summaries. Board members will not respond to individual inquiries.
Levels of Evidence
Some of the reference citations in this summary are accompanied by a level-of-evidence designation. These designations are intended to help readers assess the strength of the evidence supporting the use of specific interventions or approaches. The PDQ Adult Treatment Editorial Board uses a formal evidence ranking system in developing its level-of-evidence designations.
