Combination Chemotherapy, Biological Therapy, and Bone Marrow Transplantation in Treating Patients With Acute Myeloid Leukemia

RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Biological therapies use different ways to stimulate the immune system and stop cancer cells from growing. Combining chemotherapy with bone marrow transplantation may allow the doctor to give higher doses of chemotherapy drugs and kill more cancer cells. PURPOSE: Randomized phase III trial to compare the effectiveness of different treatment regimens in treating patients who have acute myeloid leukemia.
