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.

The aims of this study were to define the initial pathological and clinical characteristics, and prognostic factors of patients with primary breast malignant lymphoma (PBL). All patients treated at the Institut Curie for lymphoma with breast involvement were reviewed. A pathological review of all cases was performed. Forty-five cases were selected in whom 38 cases were of diffuse large B-cell lymphoma. A complete analysis was then performed on these 38 patients. Twenty out of 28 cases (71%) of cases were Bcl-2 positive and four out of 28 (14%) had a CD10 positive staining. Peculiar initial characteristics showed nodal involvement in 58% of the cases and two or more extra-nodal sites in 31% of the cases. Among the 37 patients for whom all data were available, and according to the International Prognostic Index, 19 patients (51%) were classified in the low-risk group, 5 cases (14%) in the low- to intermediate-risk group, 6 patients (16%) in the intermediate- to high-risk group, and 7 (19%) case in the high-risk group. At the end of initial therapy, 34 patients (89%) achieved CR. With a median follow-up of 96 months, 18 patients (47%) relapsed of whom 3 had a relapse in central nervous system site. The 5-year disease-free (DFS) and overall survivals (OS) were 54% and 61%, respectively. In multivariate analysis, the presence of 2 or more extranodal sites was prognostic for lower DFS (P = 0.0008) and OS (P = 0.09), and a performance status > or = 1 was prognostic for lower OS (P = 0.005). Finally, when our series was compared with a historical series of 111 patients with aggressive nodal lymphomas, we observed significant lower survival rates in localized PBL (P < 0.03). Initial breast localization has a pejorative impact on the outcome of patients with Non-Hodgkin's Lymphoma (NHL), with an impressive adverse influence of additional extranodal sites. These results suggest a specific management of NHL with breast involvement.
