PURPOSE The aim of this study was to search the BCR/ABL 1 fusion gene in 45 chronic myeloid leukemia (CML) Syrian patients using nested reverse transcription polymerase chain reaction (RT-PCR) and compare our results with those of conventional cytogenetics and molecular cytogenetics methods. METHODS 45 bone marrow or peripheral blood samples from untreated CML patients in chronic phase (CP) w...
Cytogenetic aberrations may escape detection or recognition in traditional karyotyping. The past decade has seen an explosion of methodological advances in molecular cytogenetics technology. These cytogenetics techniques add color to the black and white world of conventional banding. Fluorescence in-situ hybridization (FISH) study has emerged as an indispensable tool for both basic and clinical...
Compared with younger patients, elderly patients with acute myeloid leukemia (AML) respond poorly to conventional chemotherapy. To determine if this poor response is due to differences in the biologic characteristics of AML in the elderly, we studied 211 patients (161 de novo, 50 secondary AML) over 55 years of age (median, 68 years) registered to a single clinical trial for previously untreate...
Dear Editor The new 2008 WHO classification of hemato-oncological diseases includes a new category for recurrent chromosomal abnormalities [1]. Recurrent gene rearrangements such as RUNX1/ RUNX1T1 (formerly AML1/ETO), CBFB/MYH11, or PML/RARA, provide additional information for the diagnosis of AML, regardless of the blast count. Chromosomal abnormalities and gene mutations are the most influent...
PURPOSE The majority of patients with acute myeloid leukemia (AML) who achieve complete remission (CR) relapse with conventional postremission chemotherapy. Allogeneic stem-cell transplantation (alloSCT) might improve survival at the expense of increased toxicity. It remains unknown for which patients alloSCT is preferable. PATIENTS AND METHODS We compared the outcome of 185 matched pairs of ...
We present a new approach for modelling the dependences between genetic changes in human tumours. In solid tumours, data on genetic alterations are usually only available at a single point in time, allowing no direct insight into the sequential order of genetic events. In our approach, genetic tumour development and progression is assumed to follow a probabilistic tree model. We show how maximu...
