Summary
Brief summary (as posted)
RATIONALE: Giving colony-stimulating factors, such as G-CSF, and certain chemotherapy drugs, helps stem cells move from the bone marrow to the blood so they can be collected. Treating stem cells collected from the patient's blood or bone marrow with chemotherapy in the laboratory removes any remaining cancer cells. Chemotherapy or radiation therapy is given to the patient to prepare the bone marrow for stem cell transplant. The treated stem cells are then returned to the patient to replace the blood-forming cells that were destroyed by the chemotherapy. PURPOSE: This clinical trial is studying how well an autologous peripheral stem cell or bone marrow transplant using laboratory-treated cells works in treating patients with acute leukemia.
