Stages of Adult Acute Lymphoblastic Leukemia
Key Points for This Section
The extent or spread of cancer is usually described as stages. It is important to know whether the leukemia has spread outside the blood and bone marrow in order to plan treatment. The following tests and procedures may be used to determine if the leukemia has spread:
- Chest x-ray : An x-ray of the organs and bones inside the chest. An x-ray is a type of energy beam that can go through the body and onto film, making a picture of areas inside the body.
- Lumbar puncture : A procedure used to collect cerebrospinal fluid from the spinal column. This is done by placing a needle into the spinal column. This procedure is also called an LP or spinal tap.
- CT scan (CAT scan): A procedure that makes a series of detailed pictures of the abdomen, taken from different angles. The pictures are made by a computer linked to an x-ray machine. A dye may be injected into a vein or swallowed to help the organs or tissues show up more clearly. This procedure is also called computed tomography, computerized tomography, or computerized axial tomography.
- MRI (magnetic resonance imaging): A procedure that uses a magnet, radio waves, and a computer to make a series of detailed pictures of areas inside the body. This procedure is also called nuclear magnetic resonance imaging (NMRI).
Untreated adult ALL
- 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.
