Note: Estimated new cases and deaths from small intestine cancer in the United States in 2009:
- New cases: 6,230.
- Deaths: 1,110.
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] 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.)
