S8516-S8736-S9125-S9240 Research Study of Genes in Tissue Samples From Patients With B-cell Non-Hodgkin Lymphoma

Pharmacogenomics of Oxidative Stress-Related Genes in Lymphoma

RATIONALE: Studying samples of tissue from patients with cancer in the laboratory may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer.

PURPOSE: This research study is looking at genes in tissue samples from patients with B-cell non-Hodgkin lymphoma.

OBJECTIVES:

• To determine if toxicity following treatment for lymphoma varies according to genetic polymorphisms in oxidative stress-related genes (i.e., SOD2, CAT, GPX1, GSTM1, and GSTP1).
• To assess whether these genetic polymorphisms are associated with progression-free survival and/or overall survival in these patients treated for lymphoma.

OUTLINE: Previously collected samples are used for biomarker analysis.

DISEASE CHARACTERISTICS:

• Diagnosis of aggressive B-cell non-Hodgkin lymphoma

  • Previously treated with curative intent using anthracycline-based therapies

• Previously collected paraffin-embedded diagnostic tissues from clinical trials that were collected as part of SWOG treatment protocols (S8516, S8736, S9125, S9240, and S9349) available

PATIENT CHARACTERISTICS:

• Not specified
