Brief Summary

This randomized phase III trial is studying different combination chemotherapy regimens and comparing how well they work in treating patients with newly diagnosed acute lymphoblastic leukemia. Drugs used in chemotherapy work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Giving more than one drug (combination chemotherapy) may kill more cancer cells.

Conditions

Acute Lymphoblastic Leukemia; Childhood B Acute Lymphoblastic Leukemia

Outcome Measures

Primary Outcomes (2)

• Event-free Survival (EFS) for SR-Low Patients

  Event Free Probability where EFS time is defined as time from randomization to first event (relapse, second malignant neoplasm, death) or date of last contact for patients who are event-free.

Study Arms (8)

Group 0 Induction Therapy

EXPERIMENTAL

All patients receive cytarabine intrathecally (IT) on day 1; vincristine IV on days 1, 8, 15, and 22; dexamethasone IV or orally (PO) twice daily (BID) on days 1-28; pegaspargase intramuscularly (IM) (may give IV over 1 to 2 hours) on day 4, 5, or 6; and methotrexate IT on days 8 and 29 (and days 15 and 22 for patients with CNS3 disease). Patients with Down syndrome (DS) receive leucovorin calcium PO at 48 and 60 hours after each dose of methotrexate IT. Patients are assessed for response on day 29. Patients with M1 bone marrow AND minimal residual disease (MRD) \< 0.1% OR MRD \>= 0.1% and \< 1% proceed to therapy in part II. Patients with M2 bone marrow OR M1 bone marrow AND MRD \>= 1% proceed to extended induction therapy. Patients with M3 bone marrow are removed from the study.
