简要总结
RATIONALE: Studying samples of DNA in the laboratory from patients who received fludarabine-based treatment may help doctors learn more about the effects of fludarabine on cells. It may also help doctors understand how well patients respond to treatment.
PURPOSE: This research study is studying DNA samples from patients with chronic lymphocytic leukemia previously treated with fludarabine-based therapy.
详细描述
OBJECTIVES:
- To identify genetic characteristics associated with the efficacy and toxicity of fludarabine-based treatment in patients with chronic lymphocytic leukemia who participated on E2997.
- To validate these genetic characteristics with a cancer cell model system to confirm association and dissect the mechanism of effect.
OUTLINE: Archived DNA samples are analyzed for genetic characteristics associated with the efficacy and toxicity to fludarabine-based treatment using Affymetrix 6.0 single nucleotide polymorphism arrays. The results are then compared with data of genes identified in a cancer cell model system, and with clinical data (response, toxicity, overall survival, and progression-free survival) associated with each patient sample.
