Chronic myelogenous leukemia (CML) with a minor bcr-abl transcript is a rare entity. We describe a 66-year-old female who was diagnosed with CML in the chronic phase. Molecular analysis of her Philadelphia chromosome using the reverse transcriptase polymerase chain reaction and subsequent sequencing revealed a minor bcr-abl transcript. Monocytosis resembling chronic myelomonocytic leukemia was observed without splenomegaly and basophilia. Her clinical course was indolent and maintained the chronic phase of CML for nearly 3 years under hydroxyurea treatment. A review of the 23 cases of m-bcr CML including this case showed the presence of monocytosis and the absence of basophilia and splenomegaly in 55.0%, 55.0%, and 70.0% of patients, respectively. The absence of basophilia was a significant finding in patients without monocytosis ( P=0.01). Although the hematological features or clinical outcomes were variable in m-bcr CML cases, all three cases at the onset of the blastic phase showed lymphoid crisis, implying an increased lymphoid leukemogenicity of minor bcr-abl transcripts.
