NEOPLASIA AIDS-related B-cell lymphoma (ARL): correlation of prognosis with differentiation profiles assessed by immunophenotypingFrom the II Department of Medicine, University Hospital of Schleswig-Holstein, Campus Kiel, Kiel, Germany; the Institute of Hematopathology and Lymphnode Registry of the University Hospital of Schleswig-Holstein, Campus Kiel, Kiel, Germany; the Kuratorium für Immunschwäche (KIS), Munich, Germany; the Hospital of St Georg, Hamburg, Germany; the Institute of Pathology, University Clinic of Cologne, Cologne, Germany; the Department of Internal Medicine, University Clinic of Cologne, Cologne, Germany; the Institute for Interdisciplinary Infectiology (IFI), Hamburg, Germany; and the University Clinic of Düsseldorf, Düsseldorf, Germany.
This study was undertaken to analyze the differentiation profiles assessed by immunophenotyping in AIDS-related B-cell lymphoma (ARL) and their relation to the clinical course. Paraffin-embedded sections of 89 ARL cases during 1989 to 2004 were stained immunohistochemically with antibodies to CD3, CD10, CD20, CD38, CD138/Syndecan-1 (Syn-1), multiple myeloma-1/interferon regulatory factor-4 (MUM1/IRF4), B-cell lymphoma protein-2 (BCL-2), BCL-6, latent membrane protein-1 (LMP-1), and Ki-67. Expression of CD10 and CD20 were associated with better overall survival (OS; P = .009 and P = .04, respectively). Expression of CD20 was associated with longer disease-free survival (DFS; P = .03), whereas expression of CD138/Syn-1 was associated with shorter DFS (P = .03). OS and DFS were worse in patients with immunophenotypic profiles related to post-germinal center (GC) differentiation (BCL-6 and CD10 negative, MUM1/IRF4 and/or CD138/Syn-1 positive) when compared with GC differentiation (P = .01). When controlled for age-adjusted International Prognostic Index (IPI), prior AIDS-defining illness (ADI), and year of ARL diagnosis, a post-GC differentiation remained significantly associated with poor OS and DFS. Expression of CD10 was associated with a preserved immunocompetence, whereas CD20 was less frequent in patients developing ARL while on highly active antiretroviral therapy (P = .04). In summary, lack of CD20 or CD10 expression and a post-germinal center signature are associated with a worse prognosis in ARL. (Blood. 2005;106:1762-1769)
