Blast crisis is the final phase in the evolution of CML, and behaves like an acute leukemia, with rapid progression and short survival. [10] Blast crisis is diagnosed if any of the following are present in a patient with CML: [18] >20% blasts in the blood or bone marrow; The presence of an extramedullary proliferation of blasts
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 .
About seven per 100,000 people are affected by MDS; about four per 100,000 people newly acquire the condition each year. [4] The typical age of onset is 70 years. [4] The prognosis depends on the type of cells affected, the number of blasts in the bone marrow or blood, and the changes present in the chromosomes of the affected cells. [3]
Accelerated phase chronic myelogenous leukemia is a phase of chronic myelogenous leukemia in which the disease is progressing. [1] Symptoms
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 ...
Conventionally, a leukocytosis exceeding 50,000 WBC/mm 3 with a significant increase in early neutrophil precursors is referred to as a leukemoid reaction. [2] The peripheral blood smear may show myelocytes, metamyelocytes, promyelocytes, and rarely myeloblasts; however, there is a mixture of early mature neutrophil precursors, in contrast to the immature forms typically seen in acute leukemia.
All ages, [3] most common in 60s and 70s. [4] It is the most common malignant cancer in children, but the cure rates are also higher for them. Causes: Inherited and environmental factors [5] Risk factors: Smoking, family history, ionizing radiation, some chemicals such as trichloroethylene, prior chemotherapy, Down syndrome.

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]
