RATIONALE: Studying samples of bone marrow from patients with cancer in the laboratory may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer. It may also help doctors predict how patients will respond to treatment.

PURPOSE: This research study is studying biomarkers in bone marrow samples from patients with T-cell acute lymphoblastic leukemia.

Condition Intervention
Genetic: gene expression analysis
Genetic: microarray analysis
Other: laboratory biomarker analysis

Study Type: Observational
Official Title: Biological Correlates With T-cell Acute Lymphoblastic Leukemia (T-ALL) Gene Expression and Clinical Outcome

Primary Outcome Measures:
  • Association between induction failure status predicted by 116-member genomic classifier and actual induction therapy outcome observed on COG study AALL0434 [ Designated as safety issue: No ]

Estimated Enrollment: 135
Study Start Date: April 2011
Estimated Primary Completion Date: January 2013 (Final data collection date for primary outcome measure)
Detailed Description:


  • To confirm an association between induction failure (IF) status predicted by a previously identified 116-member genomic classifier and actual induction therapy outcome observed on COG study AALL0434.
  • To explore whether there is an association between early relapse (as defined by bone marrow or extramedullary relapse within 18 months of diagnosis) predicted by previously identified 5-member (primary) and 57-member (secondary) genomic classifiers, and actual relapse status at 18 months on COG study AALL0434. (Exploratory)

OUTLINE: RNA from cryopreserved bone marrow samples are analyzed for gene expression by microarray methods. Samples are then compared with the 116-member genomic classifier.


Ages Eligible for Study:   1 Year to 30 Years
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No


  • Newly diagnosed T-cell acute lymphoblastic leukemia
  • Cryopreserved bone marrow from the Children Oncology Group (COG) Cell Bank of patients enrolled on COG-AALL03B1 and COG-AALL0434, including the following:

    • 30 samples from patients who had > 25% bone marrow blasts at day 29 (induction failure [IF] cases)
    • Samples of cases of bone marrow and/or CNS relapse occurring within the first 18 months of treatment
    • Random samples of 105 non-IF cases who achieved remission at the end of induction therapy (at least 18 months)
