This is the process that allows for collection of the autologous stem cells (the cells that will be used to do the transplant). All participants will receive the drug idarubicin by vein for 3 days together with cytarabine by vein for 3 days. This will be followed by injections of filgrastim (Neupogen) under the skin twice a day until the white count has recovered and the stem cells are collected. During the process, the number of stem cells in the blood will be measured. When the number of cells reach a certain level, participants will go through a collection procedure known as apheresis.
