BACKGROUND Trisomy 12 was found to be the most frequent chromosomal aberration identified by conventional cytogenetic studies of bone marrow cells and peripheral lymphocytes of patients with CLL. Molecular-cytogenetic techniques which enable examination of dividing and/or non-diving interphase nuclei (I-FISH), proved existence of other chromosomal(More)
BACKGROUND It was found by classical cytogenetic methods that approximately 80% of X-chromatin positive mates have karyotype 47,XXY and the rest have mosaicism of sex chromosomes. More sensitive molecular-cytogenetic studies allow to evaluate even non-dividing cells of different tissues and therefore they suggest that there could be more frequent occurrence(More)
BACKGROUND The aim of this study was to investigate the rearrangement of MLL gene in bone marrow cells of patients with hematological malignancies with various types of 11q aberrations. These aberrations have been observed in acute lymphoblastic and acute myeloid leukemias as well as in myelodysplasias and lymphomas. METHODS AND RESULTS Correlations of(More)
BACKGROUND B-chronic lymphocytic leukemia (B-CLL) is the most common adult leukemia in the Western countries. Any routinely used staging system does not distinguish exactly the probable course of the disease at the time of diagnosis. Therefore the new prognostic factors, which help to assess the optimal therapeutic plan of patients, are searched(More)
Classical cytogenetic analysis plays an important role in the diagnosis, classification, therapy monitoring and prognosis of patients with leukemia. Many recurrent cytogenetic abnormalities with major prognostic values have been described in childhood ALL. Hyperdiploidy and/or t(12;21) are associated with good prognosis, whereas t(9;22) and/or(More)
BACKGROUND The B-chronic lymphocytic leukemia (B-CLL) has highly variable prognosis. Possibility of more relevant prognosis has a great impact for the beginning and mode of therapy. METHODS AND RESULTS One hundred patients diagnosed as having B-CLL were included into the study. Beside usual examinations necessary to establish the diagnosis, cytogenetic(More)
In a 66 years old female patient with acute myeloblastic leukemia (AML) complex chromosomal rearrangements involving 11q23 were diagnosed by G-banding and confirmed by different fluorescence in situ hybridization (FISH) techniques. The amplification of MLL gene differed in various sidelines as shown by locus specific probes for 11q23 and 11q13. Complex(More)
BACKGROUND According to the literature approximately 50% of patients with Turner's syndrome have karyotype 45,X in every cell, the rest have two or more cell lines with mosaics of sex chromosomes. New methods have shown that the mosaicism is probably more frequent than expected from classical cytogenetics examinations. The aim of this study was to detect(More)
