The current evidence regarding the usefulness of whole-body diffusion-weighted magnetic resonance imaging (DWI) in lymphoma is reviewed. DWI is capable of combining anatomical and functional information and is becoming a valuable tool in oncology, in particular for staging purposes. DWI may prove to be a useful biomarker in clinical decision making for(More)
Rituximab, a chimeric monoclonal antibody that binds specifically to the CD20 antigen, induced objective responses in 50% of patients with low-grade or follicular B-cell lymphoma. Because most nonfollicular B-cell lymphomas also express the CD20 antigen, we conducted a phase II study to evaluate the efficacy and tolerability of this new agent in patients(More)
Peripheral T-cell lymphomas (PTCL) have been generally reported to have a worse prognosis than B-cell lymphomas (BCL). Because of their heterogeneity and scarcity, the outcomes of the different histological subtypes have not been compared. From October 1987 to March 1993, 1,883 patients with diffuse aggressive non-Hodgkin's lymphomas (NHL) included in the(More)
BACKGROUND As rituximab combined with CHOP improves complete remission and overall survival in diffuse large B-cell lymphoma, intensified chemotherapy followed by autologous stem-cell transplantation has also been advocated for high-risk patients. The aim of this study was to establish whether or not combining rituximab with high-dose chemotherapy and(More)

Patients with aggressive non-Hodgkin's lymphoma who fail to achieve a complete remission (CR) with standard induction therapy have a poor prognosis with conventional-dose salvage therapy alone. Retrospective series have suggested that early introduction of high-dose salvage therapy with autologous stem cell transplantation (ASCT) may benefit(More)
Using current diagnostic criteria, primary mediastinal B cell lymphoma (PMBL) cannot be distinguished from other types of diffuse large B cell lymphoma (DLBCL) reliably. We used gene expression profiling to develop a more precise molecular diagnosis of PMBL. PMBL patients were considerably younger than other DLBCL patients, and their lymphomas frequently(More)
BACKGROUND The incidence of secondary central nervous system (CNS) occurrences in diffuse large-B-cell lymphoma is not sufficiently high to warrant the use of CNS prophylaxis in all patients. The addition of rituximab increases the complete response rate and prolongs event-free and overall survival in elderly patients with such lymphoma. PATIENTS AND(More)
Non-germinal center small B-cell lymphomas represent a heterogeneous group of non-Hodgkin lymphomas, the most frequent histologic subtypes being small lymphocytic lymphoma (SLL), splenic marginal zone B-cell lymphoma (MZL), and mantle cell lymphoma (MCL). In order to identify genomic signatures specific for each disease, we analyzed 128 primary tumors using(More)
The purpose of this study is to correlate the presence of TP53 gene mutations with the clinical outcome of a cohort of patients with diffuse large B-cell lymphoma (DLBCL) assembled from 12 medical centers. TP53 mutations were identified in 102 of 477 patients, and the overall survival (OS) of patients with TP53 mutations was significantly worse than those(More)
