Purpose
RATIONALE: Gathering health information about patients with acute lymphoblastic leukemia may help doctors learn more about the disease and plan the best treatment.
PURPOSE: This research study is developing a risk-based classification system for patients with newly diagnosed acute lymphoblastic leukemia.

| Official Title: | Classification of Newly Diagnosed Acute Lymphoblastic Leukemia |
- Development of a risk-based classification system to be used to assign patients newly diagnosed with acute lymphoblastic leukemia (ALL) to frontline specific-treatment studies [ Designated as safety issue: No ]
- Development of a classification data for correlative studies [ Designated as safety issue: No ]
- Development of a central reference guide for required and research ALL studies [ Designated as safety issue: No ]
- Development of leukemia and germline specimens for current and future research [ Designated as safety issue: No ]

| Estimated Primary Completion Date: | April 2015 (Final data collection date for primary outcome measure) |
OBJECTIVES:
- To provide a risk-based classification system based on clinical, pathological, molecular, and early response data that will be used to assign all patients with newly diagnosed acute lymphoblastic leukemia (ALL) to the Children's Oncology Group (COG) frontline specific-treatment studies.
- To capture classification data for correlative studies accompanying current COG ALL treatment protocols.
- To provide a central reference guide for all required and research studies that will be conducted in local and reference laboratories for all newly diagnosed ALL patients.
- To provide a mechanism for optional banking of leukemia and germline specimens for current and future research.
OUTLINE: This is a multicenter study. Patients are stratified according to diagnosis (B-cell precursor vs infant vs T-cell acute lymphoblastic leukemia [ALL]).
Patients undergo blood sample collection and bone marrow biopsies at baseline and during and after induction therapy for immunophenotyping for ALL confirmation and classification, DNA ploidy, genomic variation, and cytogenetic (BCR-ABL, trisomies 4+10, and molecular testing for translocations) analysis by flow cytometry and FISH. Immunophenotype results obtained on this study are used to determine patient's assignment to specific clinical-trial treatments.
Some samples (leukemic and germline) may be banked for current and/or future analyses.

DISEASE CHARACTERISTICS:
Newly diagnosed acute leukemia meeting 1 of the following criteria:
- ≥ 25% blasts by bone marrow aspirate
- Acute leukemia diagnosed by bone marrow biopsy
- Complete blood count with documented leukemia blasts of ≥ 1,000/μL
Patients with suspected acute lymphoblastic leukemia (ALL) who have true biphenotypic or bilineage leukemia (i.e., patient with significant blasts expression of multiple lymphoid and myeloid markers that cannot be assignment to a single lineage) are allowed to enroll in AALL08B1 cell banking
- No patients with blast-myeloid morphology or whose blasts are myeloperoxidase positive
- Patients with high-risk or very high-risk disease may enroll in AALL1131
- No secondary ALL
PATIENT CHARACTERISTICS:
- Not specified
PRIOR CONCURRENT THERAPY:
No prior cytotoxic therapy
- Prior steroids or intrathecal chemotherapy allowed
