title: Non-randomness in complex translocations of chronic myeloid leukaemia.
abstract: A new case of chronic myeloid leukaemia with a complex translocation involving chromosomes No. 1, 9 and 22 is reported. The striking similarity of this case with another previously reported case and the involvement of band 9q34 in chromosome rearrangements in CML patients indicates clearly a non-randomness of chromosome abnormalities in this blood disease, even when the translocation is different from the usual t(9;22) one. The usefulness of R-banding techniques is emphasized in these cases.
