Study Arms:
- Cohort I (pediatric BL) (Type: EXPERIMENTAL): Patients receive cyclophosphamide IV and vincristine IV on day 1, and prednisone IV or PO on days 1-7 in the absence of disease progression or unacceptable toxicity. Patients then receive rituximab IV or rituximab hyaluronidase SC, cyclophosphamide IV, vincristine IV, and methotrexate IV on day 1. Cycles repeat every 14 days for 6 cycles in the absence of disease progression or unacceptable toxicity.
- Cohort II (DLBCL) (Type: EXPERIMENTAL): Patients receive rituximab IV or rituximab and hyaluronidase human SC, cyclophosphamide IV, doxorubicin IV, and vincristine IV on day 1, and prednisone PO on days 1-5 of cycle 1. Cycles repeat every 21 days for 6 cycles in the absence of disease progression or unacceptable toxicity.
- Cohort III (Adult BL) (Type: EXPERIMENTAL): Patients receive rituximab IV or rituximab and hyaluronidase human SC in day 1, etoposide IV, doxorubicin IV, and vincristine IV on days 1-4. Patients also receive cyclophosphamide IV on day 5 and prednisone PO on days 1-5. Treatment repeats every 21 days for 6 cycles in the absence of disease progression or unacceptable toxicity.
- Cohort IV (MCD) (Type: EXPERIMENTAL): Patients receive rituximab IV or rituximab and hyaluronidase human SC on days 1, 8, 15, and 22 in the absence of disease progression or unacceptable toxicity.
