Summary Between 1981 and 1986 cytogenetic studies of bone marrow and/or blood cells in 139 patients with de novo acute myeloid leukemia (AML) were performed. The overall incidence of chromosomal aberrations was 53%, and this was not significantly influenced by sex, age nor the FAB classification. The aberrations most often found were: complex anomalies (n=13), t(8; 21) (n=10), trisomy 8 (n=9), monosomy 7 (n=6), monosomy 5, 5q-, trisomy 11, 12p- (n=4) and trisomy 6, 11q-, inv [16] (n=3). The prognostic significance of chromosomal findings was evaluated in 112 patients treated by combination chemotherapy. The chromosomal status NN, AN, AA did neither significantly influence complete remission rate (NN: 68%, AN: 71%, AA: 60%) nor mean survival (NN: 24, AN: 26.6, AA: 35.6 months). On the other hand, certain types of chromosomal anomalies were of prognostic value. CR was obtained in all 10 patients with t(8; 21) but only in 2 out of 9 patients with complex aberrations. Median duration of CR in patients with t(8; 21) was significantly longer than in patients with a normal karyotype (30 vs 7 months).
