Leukemia is a cancer of the white blood cells that spreads throughout the bloodstream and may affect many organs. It originates in the bone marrow (spongy center of bones), which is where all blood cells are developed before being released into the bloodstream. Leukemia is classified based on the type of abnormal white blood cell and by how rapidly these cells leave the bone marrow and enter the bloodstream. Acute myeloid leukemia (AML) is the most common type of leukemia that affects adults. The December 22/29, 2010, issue of JAMA includes an article about the association between genetic characteristics of leukemia cells and outcomes of the disease. This Patient Page is based on one published in the June 10, 2009, issue of JAMA.
Fevers with night sweats
Swollen or bleeding gums
Loss of appetite
Enlarged liver or spleen
Bone or joint pain
Complete medical history and physical examination
Bone marrow aspiration and biopsy (taken with a needle, usually from the hip)
Echocardiogram (ultrasound) of the heart
Treatment is determined by
The age of the patient and differs for those younger than 60 compared to those older than 60
Whether the patient has received prior chemotherapy
Whether the patient has other medical problems
Treatment is carried out in 2 phases:
Induction uses chemotherapy to induce remission (normal-appearing blood and bone marrow).
Consolidation therapy is used to achieve a long-lasting remission. The type of treatment offered in this phase depends on the response to the treatment used in the induction phase.
Consolidation therapy options include
Stem cell transplant from the patient himself or herself in remission (autologous) or from an identical twin (syngenic)
Allogeneic stem cell transplant from a matched healthy donor
Investigational (within a clinical trial) therapy
