title: Cytogenetic investigations on children with acute non-lymphocytic leukemia.
abstract: Cytogenetic data from 30 children with acute non-lymphocytic leukemia (ANLL) are evaluated in connection with patient's age, morphological type of leukemia and prognosis. In 20 out of 30 patients clonal chromosome aberrations were found. The frequency of chromosome aberrations and the prognostic parameters in the various morphological and age groups proved to be different and no direct relationship could be found in a given group between the frequency of aberrations and the prognosis. A more detailed analysis of data, however, provided some evidence that chromosome aberrations observed at diagnosis had a prognostic value independent of age and the morphological properties of blast cells: the normal karyotype and the pseudodiploidy proved to be of a favorable value but the hyperdiploidy and polyploidy an unfavorable prognostic parameter. Besides the known cytogenetic differences between childhood and adult ANLL, some similarities are also emphasized.
