NCT00499070

Brief Summary

RATIONALE: Studying biopsy, bone marrow, and blood samples from patients with cytopenia that did not respond to treatment may help doctors learn more about the disease and plan the best treatment. PURPOSE: This laboratory study is assessing immune function in young patients with cytopenia that did not respond to treatment.

Outcome Measures

Primary Outcomes (3)

  • Number of patients with TCR V beta oligoclonality at diagnosis

    96 months

  • Immunophenotype of patients with oligoclonal T-cell expansion

    96 months

  • Number of patients with glycophosphatidylinositol (GPI) deficient clones

    96 months

Secondary Outcomes (4)

  • Number of patients with molecular response as compared to hematological response after IST

    96 months

  • Number of patients with HLA-DR15 antigen expression and molecular response as compared to number of patients with other HLA-DR antigens and molecular response

    96 months

  • Overall survival

    96 months

  • Failure-free survival

    96 months

Interventions

For analyzing GPI deficient clones full blood will be analyzed by phenotyping using flowcytometry. For that purpose CD14, CD16 and CD24 expression will be evaluated in CD45 positive cells. Erythroid cells will be evaluated for CD55 and CD59 expression searching for clear populations with a lack of GPI-linked molecules. In addition, immunophenotyping using flowcytometry will be performed to evaluate which differentiation stages of the major hematopoietic lineages in BM and PB are associated with TCRVβ repertoire skewing. Comparison between BM and PB will identify which is the optimal compartment to analyze the responsible hematopoietic clones.
