The first phase is called remission induction therapy . The purpose of remission induction therapy is to kill as many of the leukemia cells as possible and make patients go into remission. It is also intended to prevent the spread of cancer cells to the brain and spinal cord, even if no cancer has been detected. Radiation therapy to the brain may also be given in addition to chemotherapy for this purpose. Once a child goes into remission and there are no signs of leukemia, a third phase of treatment called consolidation or intensification therapy is given.
Consolidation therapy uses high-dose chemotherapy to attempt to kill any remaining leukemia cells.
The fourth phase of treatment, called maintenance therapy , uses chemotherapy for several years to maintain the remission.
