Abstract

The cytogenetic data of 77 patients (47 adults and 30 children) with myelodysplastic syndromes and acute non-lymphoid leukemia are evaluated with regard to the morphological types of leukemia and prognosis. The groups of the adult patients were found to be different in the frequency and types of non-random chromosome aberrations. In patients with secondary leukemias and mutagen-related leukemias the incidence of chromosomal abnormalities was higher than in those with the idiopathic form of the disease. Specific abnormalities were total or partial loss of chromosome 5 and/or 7, and an additional chromosome 8. In contradistinction to these the patients with primary leukemias had specific translocations associated with pseudodiploidy. We found the frequency of aberrations in adults exposed to mutagen agents similar to that in children with ANLL, but the types of aberrations were similar to those of adults without any exposition. Comparing the median duration of remission and survival of patients' groups with different cytogenetic findings we found the chromosome aberrations to be of prognostic value. The present data demonstrate the usefullness of cytogenetic investigations in the diagnosis of the disease and in morphological and etiological classification of patients.
