Experimental: Group 0 Induction Therapy
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.

- Event-free Survival (EFS) for SR-Average ALL Patients [ Time Frame: 6 years ]EFS for SR-Average with standard and Intensified Consolidation. 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.
- Event-free Survival (EFS) for SR-Low Patients [ Time Frame: 6 years ]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.
- Health-related Quality of Life Relative to Physical, Social and Emotional Impairment [ Time Frame: At 1, 6 and 12 months after diagnosis and, 3 months post-therapy ]To identify potentially modifiable factors associated with impaired health related quality of life (HRQOL) at different periods of therapy in the patients who are SR-average enrolled on the standard risk ALL study.Standardized scores will be computed for child function using the gender and age-adjusted scores available from normative data from a healthy population of about 10,000 children. The various domains of family functioning will be assessed using well-validated instruments and analyzed as a dichotomous variable (impaired vs. non-impaired family functioning). Multiple regression analysis will be used to test the effect of family functioning (adjusted for therapy given, age at diagnosis, gender, socioeconomic status and other factors) on child function.
- Event-Free Survival Probability According to MRD Status End Induction (Day 29) [ Time Frame: MRD at Day 29 of therapy ]Event-Free survival by Day 29 MRD status (negative vs positive), Event Free Probability (time from study entry to first event (relapse, second malignant neoplasm, death) or date of last contact for patients who are event-free.
- Overall Survival Probability (OS) According to Induction Day 29 MRD Status [ Time Frame: Overall Survival Probability of 6 years ]Overall survival by Day 29 MRD status (negative vs positive), Overall survival defined as time from study entry to death or date of last contact for patients who are alive.
- Early Marrow Status (EMS) by MRD Status End Induction (Day 29) [ Time Frame: Early Marrow Status at Day 15, MRD Status at Day 29 of therapy. ]Early Marrow Status defined as M1 versus M2/M3 marrow is correlated with MRD (Positive vs. Negative)
- Optimal Time Point for Advance Health Related Quality of Life Intervention [ Time Frame: At 1 month after diagnosis and 3 months post-therapy. ]Percentage of patients with elevated Anxiety.
- Event-free Survival (EFS) for SR-High Patients. [ Time Frame: 6 years ]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.
- Event-Free Survival (EFS) for Low MRD (Negative) Subjects by Genetic Subset (TEL/Trisomy Positive vs Negative) [ Time Frame: 6 years ]Event-free probability where EFS 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.

- Patients receiving prior steroid therapy may be eligible for AALL0331 study
- Patients with a contraindication to additional asparaginase therapy, following Induction, are not eligible for the Standard Risk-Low study, and should be removed from protocol therapy at the end of Induction
- Patients who are assigned to the standard risk-average group following Induction and who meet the HRQOL
- Age at diagnosis >= 2 years (note that this is a more restrictive age range than for the therapeutic component of the study)
- At least one parent with reading comprehension of English or Spanish languages for which validated surveys exist
- Diagnosis at one of the institutions participating in this limited institution correlative study
- A parent or legal guardian must sign a written informed consent/parental permission for all patients
