RATIONALE: Studying samples of bone marrow from patients with cancer and from healthy volunteers in the laboratory may help doctors learn more about changes that occur in bone marrow stromal (connective tissue) cells.
It may also help doctors understand the effects of alkylating agents on bone marrow stromal cells.
PURPOSE: This laboratory study is evaluating stromal cells in patients with acute myeloid leukemia, myelodysplastic syndromes, or Fanconi anemia; in patients who were exposed to alkylating agents; and in healthy volunteers.

Genetic: cytogenetic analysis Genetic: fluorescence in situ hybridization Other: flow cytometry Procedure: biopsy |
Study Type: | Observational |
Official Title: | Stromal Injury and Clonal Adaptation in Myelodysplasia |
Estimated Enrollment: | 24 |
Study Start Date: | June 2002 |
OBJECTIVES:
Primary
Secondary
OUTLINE: Patients and healthy volunteers undergo bone marrow sample collection. Progenitor cells are grown in culture. Cell survival is quantified by flow cytometric and cytogenetic analysis, sister chromatid exchange, and FISH for chromosome 11 changes (for etoposide-exposed samples only).
PROJECTED ACCRUAL: A total of 24 patients and healthy volunteers will be accrued for this study.
