Blastic phase chronic myelogenous leukemia is a phase of chronic myelogenous leukemia in which more than 30% of the cells in the blood or bone marrow are blast cells (immature blood cells). When tiredness , fever , and an enlarged spleen occur during the blastic phase, it is called blast crisis .
Blast crisis is the terminal phase of CML and clinically behaves like an acute leukemia. Drug treatment will usually stop this progression if early. One of the drivers of the progression from chronic phase through acceleration and blast crisis is the acquisition of new chromosomal abnormalities (in addition to the Philadelphia chromosome). [7]
At least one case of FIP1L1-PDGFRA fusion gene-induced eosinophilic leukemia presenting with myeloid sarcoma and eosinophilia has been reported. This form of myeloid sarcoma is distinguished by its highly successful treatment with imatinib (the recommended treatment for FIP1L1-PDGRGA fusion gene-induced eosinophilic leukemia) rather than more aggressive and toxic therapy.
The drug is approved in multiple contexts of Philadelphia chromosome-positive CML, including after stem cell transplant, in blast crisis, and newly diagnosed. [ 12 ] Due in part to the development of imatinib and related drugs, the five-year survival rate for people with chronic myeloid leukemia increased from 31% in 1993, to 59% in 2009, [ 13 ...
K562 cells are of the erythroleukemia type, and the cell line is derived from a 53-year-old female chronic myelogenous leukemia patient in blast crisis. [1] [2] The cells are non-adherent and rounded, are positive for the bcr:abl fusion gene, and bear some proteomic resemblance to both undifferentiated granulocytes [3] and erythrocytes. [4]
A score of 0 indicates a low risk group' 1-2 indicates an intermediate risk group and 3-4 indicates a high risk group. The cumulative 2 year survival of scores 0, 1-2 and 3-4 is 91%, 52% and 9%; and risk of AML transformation is 0%, 19% and 54% respectively. [10]

Testing available to diagnosis AML includes a complete blood count which is characterized by blood that is taken from the vein in the arm to test for leukemia, a peripheral blood smear and a bone marrow test. During a peripheral blood smear, a sample of blood is checked for blast cells, white blood cell count and changes in shape of blood cells ...
