About
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 and using drugs in different ways may kill more tumor cells.
PURPOSE: Phase II trial to study the effectiveness of combination chemotherapy in treating pediatric patients with stage III or stage IV non-Hodgkin's lymphoma.
Full description
OBJECTIVES: I. Assess the feasibility of treating all histologic subgroups of pediatric non-Hodgkin's lymphoma on one protocol, with the addition of asparaginase during the induction and consolidation phases for diffuse lymphoblastic lymphoma and T-cell, large noncleaved cell diffuse lymphoma. II. Assess whether intensification of cyclophosphamide during induction therapy will achieve a complete response rate of 95% in 1 to 1.5 months for all histologies. III. Assess whether achieving remission induction in 1 month, administering cytarabine/methotrexate by continuous infusion during consolidation therapy, and increasing the number of intrathecal methotrexate injections throughout protocol therapy decreases central nervous system relapse in these patients. IV. Assess whether a 5-year recurrence-free survival of 85% is achievable for all histologies on this protocol. V. Assess whether duration of maintenance chemotherapy may be stratified by stage and histology of disease to avoid unnecessarily prolonged chemotherapy.

Part I: CTX/DNR; plus IT ARA-C; followed by Part II: DM/VCR; plus ASP for patients with LBL, T-cell LCL, or LCALKi1T; plus IT MTX. Consolidation: 2- or 3-Drug Combination Systemic Chemotherapy with Leucovorin Rescue followed by 2- or 3-Drug Combination Systemic Chemotherapy. Part I: ARA-C/MTX with CF; plus ASP for patients with LBL, T-cell LCL, or LCALKi1T; followed by Part II: ARA-C/VP-16; plus, for patients with LBL, T-cell LCL, or LCALKi1T. Maintenance. Single-Agent Systemic Chemotherapy with Leucovorin Rescue plus Single-Agent Intrathecal Chemotherapy followed sequentially by 3 2-Drug Combination Systemic Chemotherapy Regimens. Part I: MTX; with CF; plus IT MTX; followed by Part II: CTX/VCR; followed by Part III: ARA-C/VP-16; followed by Part IV: DNR/DM.
PROJECTED ACCRUAL: 25 patients/stratum are expected to be accrued over 3 years. This study will be reviewed for early closure if more than 1 patient has PD.
