RATIONALE: Hormone therapy may stop the growth of cancer cells. Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Combining hormone therapy with chemotherapy may kill more cancer cells. It is not yet known which hormone therapy and chemotherapy regimen is most effective for acute lymphoblastic leukemia.

PURPOSE: Randomized phase III trial to compare the effectiveness of different steroid therapy and chemotherapy regimens in treating children who have acute lymphoblastic leukemia.
