Study Arms:
- Induction Not Randomized (Type: EXPERIMENTAL): Standard Induction (28 Days). M3 Marrow at Day 28 and Off Protocol Therapy.
- Induction and Oral MTX, Double Delayed Intensification CNS (Type: EXPERIMENTAL): Patients with CNS disease at diagnosis, without other unfavorable characteristics. Standard Induction (28 Days). Consolidation (28 days) and in remission Day 21 and at time of randomization, Interim maintenance I (2 months), Delayed intensification I (2 months), Interim maintenance II (2 months), Delayed intensification II (2 months), then Maintenance (12 week cycles). Cranial radiation therapy during the Consolidation phase.
- Induction and Augmented regimen (IV MTX, Double DI) (Type: EXPERIMENTAL): Patients with unfavorable characteristics. Standard Induction (14 Days), Augmented Induction (Days 14-35), Consolidation (9 weeks), Interim Maintenance I (56 Days), Delayed Intensification I (2 months), Interim Maintenance II (2 months), Delayed Intensification II (2 months), then Maintenance (84 day courses).
- Induction and Oral MTX, Single Delayed Intensification (Type: EXPERIMENTAL): Patients without CNS disease at diagnosis, with favorable cytogenetics. Standard Induction (28 Days). Consolidation (28 days) and in remission Day 21 and at time of randomization, Interim maintenance I (2 months), Delayed intensification I (2 months), Interim maintenance II (2 months) then Maintenance (12 week cycles). Biopsy-proven testicular leukemia pts at diagnosis will receive testicular radiation therapy during the consolidation phase.
- Induction and Oral MTX, Double Delayed Intensification (Type: EXPERIMENTAL): Patients without CNS disease at diagnosis, with favorable cytogenetics. Standard Induction (28 Days). Consolidation (28 days) and in remission Day 21 and at time of randomization, Interim maintenance I (2 months), Delayed intensification I (2 months), Interim maintenance II (2 months), Delayed intensification II (2 months), then Maintenance (12 week cycles). Biopsy-proven testicular leukemia pts at diagnosis will receive testicular radiation therapy during the consolidation phase.
- Induction and IV MTX, Single Delayed Intensification (Type: EXPERIMENTAL): Patients without CNS disease at diagnosis, with favorable cytogenetics. Standard Induction (28 Days). Consolidation (28 days) and in remission Day 21 and at time of randomization, Interim maintenance I (2 months), Delayed intensification I (2 months), Interim maintenance II (2 months) then Maintenance (12 week cycles). Biopsy-proven testicular leukemia pts at diagnosis will receive testicular radiation therapy during the consolidation phase.
- Induction and IV MTX, Double Delayed Intensification (Type: EXPERIMENTAL): Patients without CNS disease at diagnosis, with favorable cytogenetics. Standard Induction (28 Days). Consolidation (28 days) and in event free remission Day 21 and at time of randomization, Interim maintenance I (2 months), Delayed intensification I (2 months), Interim maintenance II (2 months), Delayed intensification II (2 months), then Maintenance (12 week cycles). Biopsy-proven testicular leukemia pts at diagnosis will receive testicular radiation therapy during the consolidation phase.
