Y-ibritumomab tiuxetan (90Y-IT) combines the benefits of a monoclonal antibody with the efficacy of radiation in the treatment of B-cell non-Hodgkin lymphoma (NHL), a remarkably radiosensitive hematologic malignancy. 90Y-IT activity has been well established in the indolent setting, being approved in front-line treatment of follicular lymphoma (FL) patients as well as salvage therapy. However, ...

OBJECTIVES To determine the prevalence of hepatitis C virus (HCV) infection in patients with B-cell non-Hodgkin's lymphoma (NHL) in British Columbia. DESIGN A cross-sectional analysis. SETTING The British Columbia Cancer Agency (BCCA), a Canadian provincial tertiary oncology referral center. SUBJECTS Consecutive patients with B-cell NHL registered onto the BCCA lymphoma database in 1996 a...

Treatment of patients with non-Hodgkin's lymphoma (NHL) is frequently hampered by development of chemoresistance. Rituximab is a chimeric mouse antihuman CD20 antibody that offers an alternative; however, its mechanism of action is not clearly understood. Treatment of lymphoma cell lines with Rituximab sensitizes the cells to the cytotoxic and apoptotic effects of therapeutic drugs, e.g., cispl...

Indolent B-cell non-Hodgkin’s lymphomas (IBCNHL) represent a heterogenous group of chronic diseases [1]. Follicular lymphomas grades 1 and 2 (FL1/2) are by far the most common, accounting for approximately 20% of all NHL worldwide. Indolent IBC-NHL also include small lymphocytic lymphoma (SLL), which is the tissue counterpart of B-chronic lymphocytic leukemia (B-CLL); [2], lymphoplasmacytic lym...

objective: verotoxin is a member of shiga toxin family. this family contains ab protein toxins with an enzymatic (a) and a binding (b) compartment. cells that have receptor (gb3) are sensitive to cytotoxic effects of toxin. it has been shown that various tumor cells have gb3 receptor and are selectively sensitive to apoptotic effect of verotoxin. studies on tumor cell lines and laboratory anima...

objective: today, special attention is paid to the use of zirconium dioxide nanoparticle (nano-zro2), a neutral bioceramic metal, particularly for drug and gene delivery in medicine. however, there are some reports implying that use of nano-zro2 is associated with cytotoxic effects like inhibiting the cell proliferation, dna damage and apoptosis. in the present study, we examined whether nano-z...

B-non-Hodgkin lymphomas (B-NHLs) use a raft-associated signalosome made of the constitutively active Lyn kinase, the tyrosine phosphorylated Cbp/PAG adaptor, and tyrosine phosphorylated STAT3 transcription factor. No such "signalosome" is found in rafts of ALK(+) T lymphoma and Hodgkin-derived cell lines, despite similar Cbp/PAG, Lyn, and STAT3 expression and similar amounts of raft sphingolipi...

AIDS (acquired immune deficiency syndrome) and ARC (AIDS-related complex) are associated with a spectrum of lymphoproliferative disorders ranging from lymphadenopathy syndrome (LAS), an apparently benign polyclonal lymphoid hyperplasia, to B cell non-Hodgkin's lymphoma (B-NHL), i.e., malignant, presumably monoclonal B cell proliferations. To gain insight into the process of lymphomagenesis in A...

Non-Hodgkin lymphoma (NHL) consists of a heterogeneous group of tumors. Population-based data on the familial risk for specific histopathologic subtypes have not been established. Such data are useful for clinical counseling and for searching tumor subtypes sharing common genetic pathways. We used the Swedish Family-Cancer Database to calculate standardized incidence ratios (SIRs) for histopath...
