title: 14q+ in Ph-positive chronic myelogenous leukemia.
abstract: Two cases of chronic myelogenous leukemia with a Ph translocation and an additional chromosome change of the long arm of a chromosome #14 (14q+) are reported. The breakpoints on chromosome #14 were identified as 14q24 and 14q32, respectively. One of the patients did not show any evidence of blastic transformation; the other patient developed a myeloid blastic crisis when the abnormal 14q+ was seen in the bone marrow cells.
