Stages of Acute Lymphoblastic Leukemia (ALL)
There is no staging for acute lymphoblastic leukemia. Treatment is determined by age of the child, the results of laboratory tests, and whether or not the patient has been previously treated for leukemia. Instead of staging, ALL is described in the following terms:
No treatment has been given except to reduce symptoms. No treatment is typically given when too many white blood cells are present in the blood and bone marrow or if there are other signs and symptoms of leukemia.
Treatment has been given and amount of white blood cells in the blood and bone marrow are normal, and no signs or symptoms of leukemia are present.
Leukemia has returned following treatment and period of remission.
Leukemia fails to go into remission following treatment.
