Hi, Tedro. From the LLS CML Phases and Prognostic Factors:
In the accelerated phase, the number of immature blast cells has risen, and sometimes new chromosomal changes, in addition to the Ph chromosome, will occur.
People with accelerated phase CML may have:
More than 20 percent basophils (type of white blood cell) in the bloodstream
More then 15, but less than 30 percent blasts in the blood and bone marrow
Low platelet counts unrelated to therapy
Increased spleen size
Worsening anemia (caused by low levels of red blood cells)
Additional chromosome abnormalities in the CML cells
In the accelerated phase, the number of CML cells grow faster and cause symptoms such as fatigue, fever, weight loss and an enlarged spleen. If untreated, accelerated phase CML will eventually transform to blast phase
