Stages of Adult Acute Myeloid Leukemia
The new (metastatic) tumor is the same type of cancer as the primary cancer. For example, if leukemia cells spread to the brain, the cancer cells in the brain are actually leukemia cells. The disease is metastatic leukemia, not brain cancer.
There is no standard staging system for adult AML.
The disease is described as untreated, in remission, or recurrent.
Untreated adult AML
In untreated adult AML, the disease is newly diagnosed. It has not been treated except to relieve symptoms such as fever, bleeding, or pain, and the following are true:
- The complete blood count is abnormal.
- At least 20% of the cells in the bone marrow are blasts (leukemia cells).
- There are signs or symptoms of leukemia.
Adult AML in remission
In adult AML in remission, the disease has been treated and the following are true:
- The complete blood count is normal.
- Less than 5% of the cells in the bone marrow are blasts (leukemia cells).
- There are no signs or symptoms of leukemia in the brain and spinal cord or elsewhere in the body.
Recurrent Adult AML
Recurrent AML is cancer that has recurred (come back) after it has been treated. The AML may come back in the blood or bone marrow.
