- Gender: ALL
- Minimum Age: None
- Maximum Age: 21 Years
- Healthy Volunteers: f

Study Arms:
- Chemotherapy Treatment (Type: EXPERIMENTAL): Patients receive vinblastine sulfate (5 mg/m2) IV and methotrexate (30 mg/m2) IV weekly for 26 weeks, then every 2 weeks for an additional 26 weeks. Treatment continues for a maximum of 1 year in the absence of unacceptable toxicity or disease progression. Patients with a complete response receive an additional 8 doses of chemotherapy. Patients are followed every 6 months for 4 years and then annually thereafter.

Based on this trial design, predict the completion outcome and termination type (if applicable).
