RATIONALE: Drugs used in chemotherapy, such as idarubicin and cytarabine, work in different ways to stop cancer cells from dividing so they stop growing or die. Monoclonal antibodies, such as gemtuzumab ozogamicin, can locate cancer cells and either kill them or deliver cancer-killing substances to them without harming normal cells. Giving monoclonal antibody therapy together with chemotherapy may kill more cancer cells. Giving healthy stem cells from a donor whose blood closely resembles the patient's blood will help the patient's bone marrow make new stem cells that become red blood cells, white blood cells, and platelets.
