The Philadelphia chromosome is present in more than 95% of chronic myeloid leukemia patients and 13% of acute lymphocytic leukemia patients. The Philadelphia translocation, t(9;22), fuses the BCR and ABL genes resulting in the expression of leukemia-specific, chimeric BCR-ABL messenger RNAs. To facilitate diagnosis of these leukemias, we have developed a method of amplifying and detecting only ...

Environmental Health Perspectives • volume 119 | number 11 | November 2011 A 469 and does not alter our conclusion that this meta-analysis provides support for an association between occupational exposure to benzene and increased risk of multiple myeloma, acute lymphocytic leukemia, and chronic lymphocytic leukemia (Vlaanderen et al. 2011). The authors declare they have no actual or potential c...

Epidemiologic evidence indicates that several markers of exposure to childhood infections are inversely associated with the risk of childhood leukemia and lymphomas. We used the Swedish Family-Cancer Database to assess the effects of number of siblings on the risk of non-Hodgkin's (n = 7,007) and Hodgkin's lymphomas (n = 3,115), leukemias (n = 7,650), and multiple myeloma (n = 1,492) by histopa...

BACKGROUND Knowledge concerning the clinical and biological presentation, as well as the outcome of treatment, of biphenotypic acute leukemia in children is limited. DESIGN AND METHODS This retrospective review analyzes the clinical features and outcome of children with biphenotypic acute leukemia diagnosed and treated over an 8-year period. According to the EGIL scoring system 24 (3.7%) of 6...

BACKGROUND Advances in treatment of acute lymphocytic leukemia increased the likelihood of developing late treatment-associated effects, such as abdominal adiposity, increasing the risk of cardiovascular disease in this population. Cranial radiotherapy is one of the factors that might be involved in this process. The aim of this study was to determine the effect of cranial radiotherapy on adipo...

Transformation of chronic lymphocytic leukemia to acute lymphoblastic leukemia is extremely rare. We describe an elderly patient whose lymphocytes on presentation were morphologically characteristic of chronic lymphocytic leukemia, but changed to lymphoblasts in a very short interval. Peripheral blood mononuclear cells were tested for surface immunoglobulins and T65 antigen at initial presentat...

Natural killer cell activity was evaluated in children with acute lymphocytic and acute myelogenous leukemia. Peripheral blood mononuclear cells isolated at the time of diagnosis and before initiation of therapy were mixed with 51Cr-labeled K562 or MOLT-4 target cells at a ratio of 100:1. In 13 consecutive cases of acute lymphocytic leukemia, the mean percentage of lysis of K562 cells (15.0%) w...

OBJECTIVE Explore the feasibility of allo- hemopietic stem cell transplants in treating patients with B cell acute lymphocytic leukemia. METHODS Between september 2006 and February 2011, fifteen patients with B cell acute lymphocytic leukemia (ALL) were treated by allo-hemopietic stem cell transplants (HSCT). Stem cell sources were peripheral blood. Six patients were conditioned by busulfan (...

Leukocytes express a major sialoglycoprotein, leukosialin, of which the apparent molecular weight (mol wt) can be variable according to the differences in 0-glycans attached to this molecule. In the present study, we analyzed the structures of 0-glycans attached to leukosialin present in various T-lymphocytic leukemia cells. T-lymphoid cells from patients with acute T-lymphocytic leukemia expre...

Fibromodulin is an extracellular matrix protein normally produced by collagen-rich tissues; the fibromodulin gene has been found to be the most overexpressed gene in B-cell chronic lymphocytic leukemia. In this study, fibromodulin was expressed at the gene level (reverse transcription-polymerase chain reaction [RT-PCR]) in all patients with B-CLL (n = 75) and in most (5 of 7) patients with mant...
