Langerhans cell histiocytosis is a type of cancer that can damage tissue or cause lesions to form in one or more places in the body.
Langerhans cell histiocytosis (LCH) is a rare cancer that begins in LCH cells (a type of dendritic cell which fights infection). Sometimes there are mutations (changes) in LCH cells as they form. These include mutations of the BRAFgene. These changes may make the LCH cells grow and multiply quickly. This causes LCH cells to build up in certain parts of the body,...
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.)
