Summary
Brief summary (as posted)
RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Combining more than one drug and giving them in different ways may kill more cancer cells. It is not yet known which regimen of combination chemotherapy is more effective for acute lymphoblastic leukemia PURPOSE: Randomized phase III trial to compare different regimens of combination chemotherapy in treating children who have newly diagnosed acute lymphoblastic leukemia.
