Langerhans cell histiocytosis (LCH) in adults is a lot like LCH in children and can form in the same organs and systems as it does in children. These include the endocrine and central nervous systems, liver, spleen, bone marrow, and gastrointestinal tract. In adults, LCH is most commonly found in the lung as single-system disease. LCH in the lung occurs more often in young adults who smoke. Adult LCH is also commonly found in bone or skin.
As in children, the signs and symptoms of LCH depend on where it is found in the body. See the section for the signs and symptoms of LCH.
Tests that examine the organs and body systems where LCH may occur are used to detect (find) and diagnose LCH. See the section for tests and procedures used to diagnose LCH.
In adults, there is not a lot of information about what treatment works best. Sometimes, information comes only from reports of the diagnosis, treatment, and follow-up of one adult or a small group of adults who were given the same type of treatment.
Treatment Options for LCH of the LungTreatment for LCH of the lung in adults may include:
Sometimes LCH of the lung will go away or not get worse even if it's not treated.
- Quitting smoking for all patients who smoke. Lung damage will get worse over time in patients who do not quit smoking. In patients who quit smoking, lung damage may get better or it may get worse over time.
- Steroid therapy.
- Lung transplant for patients with severe lung damage.
Treatment Options for LCH of the BoneTreatment for LCH that affects only the bone in adults may include:
Treatment Options for LCH of the SkinTreatment for LCH that affects only the skin in adults may include:
Treatment for LCH that affects the skin and other body systems may include:
Treatment Options for Single-System and Multisystem LCHTreatment of single-system and multisystem disease in adults may include:
For more information about LCH trials for adults, see the Histiocyte Society Web site.
Check for U.S. clinical trials from NCI's list of cancer clinical trials that are now accepting patients with adult Langerhans cell histiocytosis. For more specific results, refine the search by using other search features, such as the location of the trial, the type of treatment, or the name of the drug. Talk with your child's doctor about clinical trials that may be right for your child. General information about clinical trials is available from the NCI Web site.
