Stages of Adult Acute Lymphoblastic 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 ALL.

    The disease is described as untreated, in remission, or recurrent.

    Untreated adult ALL

    The ALL is newly diagnosed and has not been treated except to relieve symptoms such as fever, bleeding, or pain.

    • The complete blood count is abnormal.
    • More than 5% of the cells in the bone marrow are blasts (leukemia cells).
    • There are signs and symptoms of leukemia.

    Adult ALL in remission

    The ALL has been treated.

    • The complete blood count is normal.
    • 5% or fewer of the cells in the bone marrow are blasts (leukemia cells).
    • There are no signs or symptoms of leukemia other than in the bone marrow.
