Dissemination in the central nervous system (CNS) in patients with aggressive lymphoma is a relatively rare but a frequently deadly complication that occurs between 5 (diffuse large B-cell lymphoma, DLBCL) and 30% (Burk itt lymphoma, BL and B-cell lymphoblastic lymphoma, B-LL) [1] in different subtypes of non-Hodgkin lymphoma (NHL). However, although a CNS prophylaxis is normally included into ...

The biological role of monocytes and macrophages in B-cell non-Hodgkin lymphoma (NHL) is not fully understood. We have previously reported that monocytes from patients with B-cell NHL have an immunosuppressive CD14(+)HLA-DR(low/-) phenotype that correlates with a poor prognosis. However, the underlying mechanism by which CD14(+)HLA-DR(low/-) monocytes develop in lymphoma is unknown. In the pres...

Although several studies have shown a lower risk of non-Hodgkin lymphoma (NHL) in alcohol drinkers compared with nondrinkers, the dose-response relation and potential differences between former and current drinking and across beverage types and subtypes are unclear. The authors examined associations of alcohol intake with risk of NHL and NHL subtypes in the Cancer Prevention Study II Nutrition ...

T-cell non-Hodgkin's lymphomas (NHL) represent approximately 10-15% of all lymphomas diagnosed in Western countries. Significant progress has been made over the last 2 decades in defining non-random chromosomal abnormalities. Cytogenetic and molecular analyses have enhanced diagnostic capabilities as well as improved classification and prognostication for T-cell NHL. Gamma-delta T-cell receptor...

background : there are only a few reports that exist regarding primary non-hodgkin lymphoma of the genital tract. in this article, one case of primary b-cell type non-hodgkin lymphoma (nhl) of the cervix is presented. case history: a 45 year-old woman presented bloody vaginal  discharge. upon vaginal examination, the cervix was found to be enlarged. cervical biopsy revealed b-cell type non-hodg...

The use of hair dyes has been inconsistently associated with an increased risk of lymphomas. To further evaluate this possibility, we examined hair dye use and lymphoma risk in a case-control study in the Thai population. A total of 390 histologically confirmed incident non-Hodgkin's lymphoma (NHL) cases and 422 controls were included. Information on hair dye use was obtained through a personal...

BACKGROUND Some autoimmune and chronic inflammatory disorders are associated with increased risks of non-Hodgkin lymphoma (NHL). Because different NHL subtypes develop at different stages of lymphocyte differentiation, associations of autoimmune and inflammatory disorders with specific NHL subtypes could lead to a better understanding of lymphomagenic mechanisms. METHODS In a population-based...

Prospective studies of lifestyle and non-Hodgkin lymphoma (NHL) are conflicting, and some are inconsistent with case-control studies. The Prostate, Lung, Colorectal, and Ovarian (PLCO) Cancer Screening Trial was used to evaluate risk of NHL and its subtypes in association with anthropometric factors, smoking, and alcohol consumption in a prospective cohort study. Lifestyle was assessed via ques...

introduction: acute lymphoblastic leukemia (all) and non-hodgkin's lymphoma (nhl) are the most common childhood and adolescence malignancy respectively.due to the increasing survival of these children, today late side effects of treatments are important. therapies such as corticosteroids, cytotoxic and radiotherapy effect on bone density and put the child at risk of osteoporosis and pathol...

Non-Hodgkin lymphoma (NHL) is the sixth leading cause of cancer death in the United States and accounts for 2–3% of primary neoplasms.1 Plasmablastic lymphoma (PBL) is a rare AIDS-associated NHL of diffuse large B-cell lymphoma (DLBCL) type. It typically presents in HIV infection in the oral cavity.2 Here we discuss a case of a young woman who presented with PBL in the rectum as the initial man...
