title: Cytogenetic survey of 80 patients with acute nonlymphocytic leukemia.
abstract: The authors report a cytogenetic survey of 80 patients with acute nonlymphocytic leukemia. The prognostic value of chromosome aberrations has been evaluated with three methods. The first one showed that patients with NN or AN bone marrow cellularity have a significantly better prognosis than those with AA cellularity; the second method confirmed the relatively good prognosis for patients with t(8;21) and abnormal 16 and a poor one for those with rearrangements of chromosomes 5 and/or 7. The authors also noted, surprisingly, that patients with hyperdiploidy had a significantly poorer prognosis than those with hypodiploidy and especially pseudodiploidy. The third method showed that patients with very complex karyotypes and a worse outcome than those with simple changes. Finally, they discuss the prognostic value of unusual and/or undeciphered chromosome changes detected in 18 patients, with a mean survival of 9.6 months, showing that these changes have a negative prognostic significance.
