- Event-free survival probability at 2 years [ Time Frame: At 2 years ]The Kaplan-Meier method will be used to estimate 2-year event-free survival (EFS) from the end of Induction I along with 95% log-minus-log transformed confidence limits. EFS is defined as the time from the end of Induction I to failure to achieve remission at the end of Induction II, relapse, occurrence of a second malignancy, or death.
- Mean length on protocol therapy [ Time Frame: 6 months ]The mean number of days patients spent on protocol therapy.
- Proportion of patients with an early death [ Time Frame: 1 month ]The proportion of patients experiencing an early death in the first month.
- Overall survival probability at 2 years. [ Time Frame: 2 years ]The Kaplan-Meier method will be used to estimate 2-year Overall Survival (OS) from the end of Induction I along with 95% log-minus-log transformed confidence limits. OS is defined as the time from the end of Induction I to death.
- Proportion with treatment related mortality [ Time Frame: 6 months ]The proportion of patients experiencing a treatment related death will be reported along with a corresponding confidence interval.
- Proportion of patients experiencing a relapse risk [ Time Frame: 2 years ]The proportion of patients experiencing a relapse after achieving remission will be reported along with a corresponding confidence interval.
- Percentage of patients experiencing grade 3 or adverse events [ Time Frame: 6 months ]The percentage of patients experiencing grade 3 or higher toxicity will be reported, where adverse events are graded according to the National Cancer Institute Common Terminology Criteria for Adverse Events version 5.0.
- Mean time to absolute neutrophil count (ANC) recovery [ Time Frame: 6 months ]The mean time to recovery of ANC to at least 1000/uL will be reported.
- Mean duration of hospitalization [ Time Frame: 6 months ]Mean number of days patients are hospitalized.
- Proportion of patients with at least 1 infection [ Time Frame: 6 months ]The proportion of patients having at least one infection will be reported.

Ages Eligible for Study: | 91 Days to 3 Years (Child) |
Sexes Eligible for Study: | All |
Accepts Healthy Volunteers: | No |
Inclusion Criteria:
- Patients must have constitutional trisomy 21 (Down syndrome) or trisomy 21 mosaicism (by karyotype or fluorescence in situ hybridization [FISH])
-
Patient has one of the following:
-
Patient has previously untreated de novo AML and meets the criteria for AML with >= 20% bone marrow blasts as set out in the World Health Organization (WHO) Myeloid Neoplasm classification
- Attempts to obtain bone marrow either by aspirate or biopsy must be made unless clinically prohibitive; in cases where it is clinically prohibitive, peripheral blood with an excess of 20% blasts and in which adequate flow cytometric and cytogenetics/FISH testing is feasible can be substituted for the marrow exam at diagnosis
- Patient has cytopenias and/or bone marrow blasts but does not meet the criteria for the diagnosis of AML (WHO Myeloid Neoplasm classification) because of < 20% marrow blasts and meets the criteria for a diagnosis of myelodysplastic syndrome (MDS)
-
For patients who do not meet criteria for AML or MDS as outlined above; patient has a history of transient myeloproliferative disorder (which may or may not have required chemotherapy intervention and:
- Is > 8 weeks since resolution of transient myeloproliferative disease (TMD) with >= 5% blasts, OR
- Has an increasing blast count (>= 5%) in serial bone marrow aspirates performed at least 4 weeks apart
-
- Children who have previously received chemotherapy, radiation therapy or any anti-leukemic therapy are not eligible for this protocol, with the exception of cytarabine for the treatment of TMD
-
There are no minimal organ function requirements for enrollment on this study
- Note: Previous cardiac repair with sufficient cardiac function is not an exclusion criteria
- Each patient's parents or legal guardians must sign a written informed consent
- All institutional, Food and Drug Administration (FDA), and National Cancer Institute (NCI) requirements for human subjects research must be met
Exclusion Criteria:
- Patients with promyelocytic leukemia (French-American-British [FAB] M3)
-
Prior therapy
- Patients =< 30 days from the last dose of cytarabine used for treatment of TMD
