    Sammanfattning : In the present thesis molecular genetic methods were used to address different biological and clinical aspects of Philadelphia (Ph) chromosome-positive leukemias and the BCR and ABL genes. In the first study, children with Ph-positive chronic myeloid leukemia (CML) were found to have essentially the same breakpoint locations in BCR as adults, a pattern which differs from the one seen in Ph-positive acute lymphoid leukemia (ALL).

  2. 2. Identification and Characterization of Stem Cells in Preleukemia and Leukemia

    Författare :Lars Nilsson; Stamcellscentrum (SCC); []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Haematology; extracellulära vätskor; Hematologi; Philadelphia chromosome; acute lymphoblastic leukemia; polycytemia vera; 5q- syndrome; myelodysplastic syndromes; self-renewal; preleukemia; Hematopoietic stem cells; leukemic stem cells; extracellular fluids;

    Sammanfattning : Hematopoietic stem cells (HSCs) are responsible for the daily and life long production of large numbers of mature blood cells through highly regulated self-renewal and multilineage capabilities. Leukemias on the other hand, are characterized by a clonal, dysregulated, lineage skewed proliferation and impaired differentiation as the result of multiple accumulated genetic events. LÄS MER

  3. 3. Registry-Based Studies in Adult Acute Lymphoblastic Leukemia in Sweden : Survival and Quality of Life

    Författare :Emma Bergfelt Lennmyr; Helene Hallböök; Martin Höglund; Jan Maxwell Nørgaard; Uppsala universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Acute Lymphoblastic Leukemia; Philadelphia Chromosome; Overall Survival; Population-based; Quality Registry; Relapse; Patient-Reported Outcome; Health-Related Quality of Life; Depression;

    Sammanfattning : Acute lymphoblastic leukemia (ALL), a common child malignancy, also constitutes a minor fraction of adult cancer with approximately 50 new cases per year in Sweden. While the five-year overall survival (OS) in pediatric ALL is more than 90%, the prognosis in adults is dismal. LÄS MER

  4. 4. Clinical and experimental studies in Philadelphia chromosome negative chronic myeloproliferative disorders

    Författare :Peter Johansson; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :myeloproliferative disorders; polycythaemia vera; essential thrombocythaemia; epidemiology; erythropoietin; red-cell mass; spleen size; thrombo-embolic; PRV-1.;

    Sammanfattning : The present thesis deals with various aspects on the (a) epidemiology, (b) diagnosis, and (c) molecular biology in Philadelphia chromosome negative (Ph-) chronic myeloproliferative disorders (MPD). First, the incidence of the three Ph- MPD, polycythaemia vera (PV), essential thrombocythaemia (ET) and idiopathic myelofibrosis (IMF) was investigated in the city of Göteborg, Sweden during the years 1983-1999 (Paper I).

  5. 5. Case-control studies on risk factors for myeloid leukemias and myelodysplastic syndromes

    Författare :Jonas Björk; Avdelningen för arbets- och miljömedicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; epidemiologic methods; bias epidemiology ; attributable fraction; smoking; hobbies; occupational exposure; chromosome aberrations; epidemiology; cytogenetic; Occupational health; industrial medicine; Yrkesmedicin; arbetsmiljömedicin;

    Sammanfattning : Case-control studies comprising telephone interviews for 333 cases of acute myeloid leukemia (AML), 226 cases of Philadelphia chromosome-positive chronic myeloid leukemia (Ph+ CML), 330 cases of myelodysplastic syndromes (MDS), and matched controls were conducted. Information had to be obtained from next-of-kin much more often for cases (85%) than for controls (18%). LÄS MER
