OBJECTIVE To characterize the frequency of genetic profiles in pediatric acute lymphoblastic leukemia (ALL) patients in Kuwait. SUBJECTS AND METHODS This review presents the general cytogenetic characteristics of 164 pediatric patients diagnosed as having ALL in a 6-year period. Chromosomal and fluorescence in situ hybridization studies were made on bone(More)
INTRODUCTION Protein tyrosine kinase inhibitors are currently one of the most important classes of cancer drugs and one of the most impressive approaches of targeted cancer therapy. Aberrant activation of tyrosine kinase pathways is among the most dysregulated molecular pathways in human cancers; therefore, a large number of tyrosine kinases may serve as(More)
Adult T-cell leukemia/lymphoma is a distinct clinical entity characterized by a clonal proliferation of malignant T-lymphocytes. The etiologic agent of the disease is a Human T-cell lymphotropic virus type I. It occurs almost exclusively in areas where the virus is endemic; however the disease develops only in the minority of patients who are virus(More)
Coexistence of two specific chromosomal translocations in the same clone is an infrequent phenomenon and has only rarely been reported in hematological malignancies. We report a combination of t(16;16)(p13;q22), the Philadelphia translocation t(9;22)(q34;q11.2), and deletion of the long arm of chromosome 7 in a patient with chronic myeloid leukemia in blast(More)
We established a human lung cancer cell line, MI-4 from the pleural effusion of a 69-year-old male with advanced large cell undifferentiated carcinoma of the lung complicated by leukocytosis. The culture supernatant of MI-4 contained high levels of granulocyte colony stimulating factor (G-CSF). The intracellular localization of the G-CSF was identified by(More)
The emergence of chromosome abnormalities in Philadelphia-negative cells in chronic myelogenous leukemia patients during imatinib therapy have been described by several authors. While these abnormalities are frequently transient, in rare instances they may be presented on repeated occasions suggesting the possibility of the development of a new malignant(More)
Many biological and clinical features of chronic myeloid leukemia make it as a paradigm of rational drug design in human cancer. Chronic myeloid leukemia was the first malignancy to be linked to a clear genetic anomaly, the Philadelphia chromosome and, at present, it is probably the best understood of all human malignancies. Studies of the disease pathology(More)
We describe a case of a chronic myeloid leukemia patient displaying the chimeric BCR-ABL1 gene on 12p11. Chromosome analysis revealed complex chromosome aberration involving chromosomes 9, 12, and 22. Fluorescence in situ hybridization revealed an unusual signal pattern revealing the BCR-ABL1 fusion signal on chromosome 12, while no reciprocal ABL1-BCR(More)
