RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining more than one drug may kill more tumor cells. It is not yet known which regimen of combination chemotherapy plus steroid therapy is more effective for acute lymphoblastic leukemia or lymphoblastic non-Hodgkin's lymphoma.

PURPOSE: Randomized phase III trial to compare the effectiveness of different regimens of combination chemotherapy plus steroid therapy in treating children who have acute lymphoblastic leukemia or lymphoblastic non-Hodgkin's lymphoma.

OBJECTIVES:

• Compare the value of dexamethasone (DM) vs prednisolone (PRDL) administered during induction therapy, in terms of event-free and overall survival, in children with acute lymphoblastic leukemia (ALL) or lymphoblastic non-Hodgkin's lymphoma (LNHL).
• Assess the value of increasing the number of administrations of asparaginase during consolidation and late intensification therapy, in terms of disease-free and overall survival, in children without very high-risk (VHR) features.
• Compare the response rate in children treated with prephase therapy comprising DM vs PRDL and intrathecal methotrexate.
• Compare the incidence and grade of toxic effects of these treatment regimens in these children.
• Compare the long-term effects of these treatment regimens on growth and pubertal development, neurocognitive, cardiac, and endocrine function, and incidence of aseptic bone necrosis in these children.
• Evaluate the proportion of children with VHR disease when defined according to extended VHR criteria, and assess the prognostic importance of the new VHR features (cytogenetics and minimal-residual disease).
• Compare the feasibility of the VHR chemotherapy protocol in patients treated with DM vs PRDL.

OUTLINE: This is a randomized, multicenter study. Patients are stratified for prephase therapy according to center, disease (acute lymphoblastic leukemia [ALL] vs non-Hodgkin's lymphoma [NHL]), WBC for ALL patients (less than 10,000/mm^3 vs 10,000/mm^3 to less than 100,000/mm^3 vs greater than 100,000/mm^3), stage for NHL patients (I or II vs III or IV), and whether prephase already started (yes vs no). Patients are stratified for protocol II therapy according to center, risk group (very low risk [VLR] vs average risk 1 [AR1] vs average risk 2 [AR2]), and treatment arm at first randomization.

• Patients are randomized to 1 of 2 treatment arms
• Arm I: Patients receive oral prednisolone (PRDL) twice daily or methylprednisolone IV over 1 hour every 12 hours on days 1-7.
• Arm II: Patients receive dexamethasone (DM) orally twice daily or IV over 1 hour every 12 hours on days 1-7. Patients in both arms also receive methotrexate (MTX) intrathecally (IT) on day 1.
• VLR patients: Patients receive either oral PRDL or oral DM (depending on earlier randomization) on days 8-28; vincristine (VCR) IV on days 8, 15, 22, and 29; daunorubicin (DNR) IV over 1-4 hours on days 8 and 15; MTX IT on days 12 and 25; and asparaginase (ASP) IV over 1 hour or intramuscularly (IM) on days 12, 15, 18, 22, 25, 29, 32, and 35.
• AR1 patients: Patients receive PRDL or DM, VCR, and ASP in the same manner as VLR patients. Patients also receive DNR IV over 1-4 hours on days 8, 15, 22, and 29 and triple intrathecal therapy (TIT) comprising MTX, cytarabine (ARA-C), and hydrocortisone on days 12 and 25.

Patients with VLR, AR1, or AR2 disease after protocol IA proceed to protocol IB, interval therapy, and then protocol II. Patients with VHR disease after protocol IA proceed to the VHR patient protocol.

• VLR patients: Patients receive oral DM twice daily on days 1-21; VCR IV on days 8, 15, 22, and 29; doxorubicin (DOX) IV over 1-4 hours on days 8 and 15; ARA-C IV on days 38-41 and 45-48; oral thioguanine (TG) once daily on days 36-49; and MTX IT on day 38.
• AR patients: Patients receive DM, VCR, ARA-C, and TG in the same manner as VLR patients; DOX IV over 1-4 hours on days 8, 15, 22, and 29; CTX IV over 30-60 minutes on day 36; and TIT on day 38.
• VLR and AR patients are also randomized to 1 of 2 treatment arms.
• Arm I: Patients receive short-term ASP IV over 1 hour or IM on days 8, 11, 15, and 18.
