Expression of T Immunoregulatory Proteins in ALK+ Anaplastic Large Cell Lymphoma (ALCL)
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 predict how patients will respond to treatment.
PURPOSE: This research trial studies biomarker expression in tissue samples from young patients with anaplastic large cell lymphoma.
OBJECTIVES:
OUTLINE: Archived tissue microarray samples are analyzed by mass spectrometry and validated by Western blotting, flow cytometry, and IHC.
