The karyotype of leukemic cells of 78 acute leukemia patients (37 ANLL, 34ALL, and 7 of unknown type) was studied by means of G-banding. Chromsomal abnormalities were found in 50 patients (72%). Chromosomes 8, 21, 5, 7, 11, and 19 were preferentially involeved in the abnormalities, both in ANLL and in ALL. A high incidence of the characteristic(More)
Results of chromosome studies of blood and bone marrow cells from 101 patients with Ph1 positive chronic myeloid leukemia (CML) confirm the assumption that clinical and morphologic manifestations of the disease correlate with karyotype peculiarities of leukemic cells. Several variants of the clinical course of CML may be distinguished. One is the variant(More)
Rearrangement of the short arm of chromosome 6 with a breakpoint at 6p23 was found in five patients with myeloid leukemia. Three of them had different morphological variants of AML (M2, M3, M4) and two blastic crisis of Ph1 negative and Ph1 positive CML. Identical translocation, t(6;9)(p23;q34), was revealed in two patients. One of them had AML (M2), the(More)
The karyotype of leukemic cells was studied in 88 acute nonlymphocytic leukemia (ANLL) patients. Chromosome abnormalities were discovered in 78.4% of all patients and in 72.5% of the 69 patients studied before treatment. Characteristic abnormalities: translocations 8;21, 15;17, 9;22 or 6;9, rearrangements of 11q, gain of chromosomes 8 or 21, and loss or(More)
The leukemic cell karyotype was studied in 103 children with acute lymphoblastic leukemia. An abnormal chromosome pattern was revealed in 81 of 98 patients studied before treatment (82.6%) and in the five children studied in relapse. Aside from specific chromosomal abnormalities defined by the Third International Workshop on Chromosomes in Leukemia, other(More)
Banded chromosomes of leukemic cells were studied in 53 children with chronic myeloid leukemia (CML). Ph1 chromosome was found in 21 children, and the remaining 32 cases were Ph1 negative. Besides Ph1 translocation additional chromosomal abnormalities, including marker i(17q), were revealed in three of eight children studied in blastic crisis of Ph1(More)
