title: Chromosome band analysis in 19 cases of chronic myeloid leukemia: 9 chronic, 10 blastic, two with Ph1 (22q-) translocation on 17 short arm.
abstract: The results of Giemsa band analyses of the marrow cells of 19 cases of CML in the chronic or blast phase are reported. All but one of the 14 Ph1 positive cases showed the 9q+pattern, the exceptional one being 16p+. All 10 blast cases showed additional rearrangements, which are described. In two of the cases, one blastic, one chronic, which were -22, Ph1 negative, the 22q- member was identified as a translocation on the short arm of one 17 which was dicentric.
