chronic phase No obvious symptoms
Accelerated phase or blast phase characteristics
accelerated phase to control the number of leukocytes in the
conventional treatment
doubling time of less than 5 days
marrow or blood the Central Plains granulocytes ≥
10%
in bone marrow or blood Zhongyuan +
promyelocytes ≥ 20%
basophils + eosinophils ≥ 20%
or thrombocytopenia not improve after conventional
treatment
platelet count increased
chromosomal abnormalities involving new clone
progressive enlargement
chloroma occurred or bone marrow fibrosis
acute transformation phase
Granulocytes in bone marrow or blood Zhongyuan + promyelocytes ≥ 30%
