PRIMARY OBJECTIVES:
I. Identify baseline clinical characteristics and treatment strategies in patients with AIDS-associated primary effusion lymphoma (PEL) that correlate with long-term survival (\>= 2 years). (Primary clinical objective) II. Identify differentially expressed genes in PEL that are associated with long-term survival (\>= 2 years). (Primary genomic objective)
OUTLINE:
Medical chart review is performed and patient information is collected regarding human immunodeficiency virus human immunodeficiency virus (HIV)/AIDS medical history, staging of AIDS related malignancy, and type of treatment. Previously collected tissue samples are analyzed via ribonucleic acid (RNA) sequencing and microarray.
