Brief Summary: 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
Detailed Description: OBJECTIVES

Compare the effects of oral prednisolone vs oral dexamethasone on remission rate event-free survival and overall survival of children with acute lymphoblastic leukemia
Compare the effect of oral mercaptopurine MP vs oral thioguanine TG on remission rate event-free survival and overall survival of this patient population
Assess the effect of a schedule concentrating on tight control of maintenance therapy compensating where necessary for constitutional drug resistance and avoiding poor physician or patient compliance on event-free survival of these patients
Compare the pharmacokinetics of MP and TG in these patients
Collect data on the presence or absence of minimal residual disease in serial bone marrow samples to assess its clinical importance

OUTLINE This is a randomized multicenter study Patients are randomized twice during the study prednisolone vs dexamethasone and mercaptopurine vs thioguanine Patients are initially stratified according to risk status standard vs intermediate vs high Patients are stratified at the second randomization according to gender age under 2 years vs 2 to 9 years vs over 9 years WBC under 50000mm3 vs over 50000mm3 steroid allocation and early response slow vs rapid

Patients with verified CNS disease receive weekly intrathecal IT methotrexate until 2 consecutive clear cerebrospinal fluid samples have been obtained Cranial radiotherapy is administered over 15-21 days during weeks 5-8 concurrently with methotrexate IT in the appropriate regimen Following radiotherapy these patients receive monthly methotrexate IT for 1 year and then every 3 months until the end of therapy

Patients with testicular infiltration receive additional radiation fractions daily for 12 days to both testes during weeks 5-8
