RATIONALE: Studying samples of tissue from patients with cancer in the laboratory may help doctors identify and learn more about biomarkers related to cancer. It may also help doctors understand how patients respond to treatment.
PURPOSE: This laboratory study is looking at biomarkers using tissue samples from older patients with diffuse large B-cell lymphoma treated with combination chemotherapy with or without rituximab on clinical trial ECOG-E4494.
OBJECTIVES:
OUTLINE: Patients are stratified according to prior treatment (CHOP chemotherapy [cyclophosphamide, doxorubicin, vincristine, and prednisone] or CHOP-like chemotherapy vs CHOP chemotherapy with or without rituximab).
Tissue microarrays will be constructed using tissue samples previously collected from patients treated on clinical trial ECOG-E4494. Tissue microarrays will be used for biomarker studies.
