    Abstract:
    This study was purposed to investigate the difference of morphology, immunophenotype, cytogenetic features and prognosis between myeloid blast crisis and lymphoid blast crisis of chronic myelogenous leukemia (CML). A total of 31 patients with CML in blastic crisis in Department of Hematology, the First Affiliated Hospital of Xi'an Jiaotong University school of Medicine from 2009 January to 2014 January were enrolled in this study. Out of 31 CML patients, 24 cases were patients with myeloid blast crisis and other 7 cases were patients with lymphoblastic crisis. The clinical data, blast cell percentage in peripheral blood and bone marrow, eosinophil and basophil percentage, immunophenotype, cytogenetic characteristics and prognosis were analyzed. The results indicated that there was no significant difference of blastic cell percentage in peripheral blood and bone marrow of CML with myeloid blast crisis, and the eosinophil and basophil cells could be easily detected. The ratio of blastic cells in BM was higher than that in PB in lymphoid blastic crisis of CML, eosinophil and basophil cells were rare. 7 cases of CML with lymphoid blastic crisis were B ALL with CD10, CD19, CD34, HLA-DR expression, and 2 cases with CD13 and CD33 expression. The lymphoid score was in all CML patients with lymphoid blastic crisis was greater than or equal to 1.5;and 2 patients with CD13 and CD33 expression, and with 1 myeloid score.24 cases of myeloid blastic crisis of CML patients mainly expressed CD33, CD13, CD38, CD34, CD11b and HLA-DR, and their myeloid score greater than or equal to 2, among them the lymphoid scores of 2 patients were 0.5 and 1 score, respectively. All the 31 patients showed 100% Ph(+) chromosome, among them 3 cases also showed other new chromosome aberrations. There was no significant difference of overall survival rate between lymphoid and myeloid blastic crisis of CML, but the overall survival rate of patients treated with tyrosine kinase inhibitor (TKI ) was higher than that in the patients without TKI treatment. It is concluded that eosinophil and basophil cells in peripheral blood of lymphoid blastic crisis were less than that of CML patients with myeloid blastic crisis. Lymphoid blastic crisis of CML patients occurred mostly in B ALL cases with expression of CD10 and CD19. Patients with myeloid blastic crisis of CML mainly expressed CD33, CD13, CD38, CD34, CD11b and HLA-DR, and could be accompanied by other lineage antigen expression, but the score was less than 2. New chromosome aberration is easily observed in myeloid blastic crisis of CML. There is no significant difference of overall survival rate of between CML patients with lymphoid and myeloid blastic crisis, but the overall survival rate of patients treated with TKI is higher than the patients without TKI treatment.
