background: expression of epstein-barr virus latent member protein-1 (ebv lmp-1) and loss of p16 protein expression are documented in lymphoma, indicating a relationship between them, but this relationship is not clear and sometimes contradictory. thus, this study was conducted to examine the relationship between the loss of p16 and ebv lmp-1 expression in jordanian patients diagnosed with lymp...
The methylenetetrahydrofolate reductase (MTHFR) gene codes for the MTHFR enzyme which plays a key role in the pathway of folate and methionine metabolism. Polymorphisms of genes in this pathway affect its regulation and have been linked to lymphoma. In this study we examined whether we could detect an association between two common non-synonymous MTHFR polymorphisms, 677C > T (rs1801133) and 12...
Non-Hodgkin lymphoma (NHL) is a hematological tumor caused by abnormal lymphoid proliferation. NHL can arise in any part of the body, including central nervous system (CNS). However, pituitary involvement is a quite rare presentation. The diffuse large B-cell lymphoma (DLBCL) is the most common subtype when pituitary is infiltrated. Here, we report a case of pituitary infiltration of NHL DLBCL ...
Some autoimmune disorders are increasingly recognized as risk factors for non-Hodgkin lymphoma (NHL) overall, but large-scale systematic assessments of risk of NHL subtypes are lacking. We performed a pooled analysis of self-reported autoimmune conditions and risk of NHL and subtypes, including 29 423 participants in 12 case-control studies. We computed pooled odds ratios (OR) and 95% confidenc...
BACKGROUND Risk factors for B-cell non-Hodgkin lymphoma (B-NHL) have not been assessed among Palestinian Arabs (PA) and Israeli Jews (IJ). METHODS In a case-control study we investigated self-reported medical and lifestyle exposures, reporting odds ratios (ORs) and 95% confidence intervals [CIs], by ethnicity, for overall B-NHL and subtypes. RESULTS We recruited 823 cases and 808 healthy co...
While the effect of TGF-β on malignant B cells in non-Hodgkin lymphoma (NHL) has been previously evaluated, studies to specifically define the role of TGF-β in tumor immunity in B-cell NHL are limited. We found that soluble TGF-β, secreted by both lymphoma cells and intratumoral T cells, is present in the serum of patients with B-cell NHL. Soluble TGF-β promoted regulatory T (T(reg)) cells by e...
Non-Hodgkin lymphomas (NHL) are a heterogeneous group of hematologic malignancies typically treated with multiagent chemotherapy. Rarely, spontaneous remissions can be observed, particularly in more indolent subtypes. The prognosis of aggressive NHL can be predicted using clinical and histopathologic factors. In aggressive B-cell NHL, the importance of MYC and BCL2 proto-oncogene coexpression (...
In order to determine the appropriate treatment of malignant lymphoma, it is important to know the degree to which extra-nodal invasion of lymphoma cells has occurred. We amplified complementarity-determining region (CDR) III genes in 64% of lymph node samples at the onset or relapse of B-cell-lineage non-Hodgkin's lymphoma (NHL) in 22 patients. By using a clone-specific CDR III probe in each p...
INTRODUCTION Bortezomib , the first proteasome inhibitor (PI) to be evaluated in humans, is approved in the USA and Europe for the treatment of patients with multiple myeloma, and in the USA for patients with relapsed mantle cell lymphoma (MCL). AREAS COVERED This review examines the role of bortezomib in the therapy of non-Hodgkin's lymphoma (NHL). Bortezomib may be particularly effective ag...
A study of histopathological and clinical features of non-Hodgkin's lymphoma in 495 consecutive cases, diagnosed at AFIP during 1984-1989 is presented. Children below the age of 15 years were not included in this study. The relative frequency of non-Hodgkin's lymphoma was 4.29% in our material. Non-Hodgkin's lymphoma was more frequent than Hodgkin's disease, ratio being 2.44:1. Lymphadenopathy ...
