HIV infection is associated with a high incidence of AIDS-related lymphomas (ARLs). Since the use of highly active antiretroviral therapy (HAART), the incidence of AIDS-defining illnesses has decreased, leading to a significant improvement in survival of HIV-infected patients. The consequences of HAART use on ARL are under debate. This study compared the(More)
This study was undertaken to show that a high survival rate can be obtained in B-cell (Burkitt and large B-cell) lymphoma and L3 leukemia with multiagent chemotherapy adapted to the tumor burden (stage, resection status, percentage of blasts in bone marrow, and central nervous system [CNS] involvement) and early response to chemotherapy, to investigate(More)
Human immunodeficiency virus (HIV) is implicated in the development of AIDS (acquired immune deficiency syndrome). HIV infection leads to the generation of HIV-specific thymus-derived (T) lymphocytes in humans and apes. We describe an experimental system permitting the quantitative and systematic analysis of HIV-specific cytotoxic T lymphocytes (CTL).(More)
Most primary central nervous system lymphomas (PCNSLs) in immunocompetent patients are diffuse large B-cell lymphomas (DLBCLs), characterized by poor prognosis, compared with systemic forms. A germinal center B-cell-like (GCB) origin of PCNSL was hypothesized on the basis of BCL-6 expression and ongoing mutational activity. Our goal herein was to determine,(More)
The transcription factor family NF-kappaB/Rel is responsible for the regulation of a large number of cellular genes and some viruses. Since there is a strong similarity between the NF-kappaB/Rel family members and the Drosophila melanogaster protein DORSAL, which is activated early during embryogenesis, we were interested in determining the pattern of(More)
BACKGROUND We conducted a phase II study to evaluate in 72 adult patients the efficacy of the intensive LMB chemotherapy regimen, previously reported by the Société Française d'Oncologie Pédiatrique for children with Burkitt lymphoma and L3 acute lymphoblastic leukemia. PATIENTS AND METHODS Treatment began with a prephase (low-dose steroids, vincristine(More)
Malignant centrofacial granuloma (MCFG) is a clinical entity characterized by a relentless ulceration of the upper airway involving the nose, palate, and face, without any demonstrable etiology. The origin of 11 cases were analyzed with the help of cell-surface immunostaining in all and with T-cell receptor gene (TCR) rearrangement in 3. The results show(More)
The retrospective study of 34 patients with Hodgkin lymphoma-associated hemophagocytic syndrome led us to define this association as a specific disorder. Its characteristics are male predominance (male-to-female sex ratio, 3.3:1), immunodeficiency-like histological features (lymphocyte depletion, 45% of cases; mixed cellularity Hodgkin lymphoma subtype,(More)
Primary low grade marginal zone B cell lymphoma (MZL) of the breast and localised mammary amyloidosis are exceedingly rare entities. This report describes the case of a woman with long standing Sjögren's syndrome presenting with asymptomatic MZL of the breast showing plasmacytic differentiation, associated with local ductular amyloidosis. The lesion was(More)
Clinical studies showed that advanced stage, high LDH, poor response to reduction therapy and combined bone marrow and central nervous system disease are significantly associated with a decreased event-free survival (EFS) in pediatric mature B-cell non-Hodgkin's lymphoma (B-NHL) treated on FAB/LMB96. Although rearranged MYC/8q24 (R8q24) is characteristic of(More)
