This research trial studies clinical factors and gene expression analysis for prognosis in tissue samples from patients with acquired immune deficiency syndrome (AIDS)-related primary effusion lymphoma. Gathering health information over time and studying samples of tissue from patients in the laboratory may help doctors learn about the prognosis of patients with AIDS-related primary effusion lymphoma.
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.
