CHROMOSOME BAND ANALYSIS IN 19 CASES OF CHRONIC MYELOID LEUKEMIA - 9 CHRONIC, 10 BLASTIC, 2 WITH PHI (22Q-) TRANSLOCATION ON 17 SHORT ARM

Abstract

The results of Giemsa band analyses of the marrow cells of 19 cases of chronic myeloid leukemia in the chronic or blast phase were reported. All but one of the 14 Ph1 [Philadelphia] positive cases showed the 9q+ pattern, the exceptional one being 16p+. All 10 blast cases showed additional rearrangements, which were described. In 2 of the cases, 1 blastic, 1 chronic, which were -22, Ph1 negative, the 22q- member was identified as a translocation on the short arm of one 17 which was dicentric.
