Blastic phase chronic myeloid leukemia

Blastic phase chronic myeloid leukemia, also termed blast crisis, is the advanced, terminal stage of chronic myeloid leukemia characterized by rapid transformation of the underlying myeloproliferative neoplasm into an aggressive acute leukemia Pathophysiologically, it is defined by a failure of myeloid or lymphoid differentiation leading to an accumulation of 20% or more blast cells in the peripheral blood or bone marrow, or the presence of extramedullary blast proliferation This severe clonal p...

It primarily affects the hematopoietic system, developing in patients harboring the Philadelphia chromosome and the associated BCR::ABL1 fusion gene after acquiring secondary cytogenetic or molecular abnormalities

It primarily affects the hematopoietic system, developing in patients harboring the Philadelphia chromosome and the associated BCR::ABL1 fusion gene after acquiring secondary cytogenetic or molecular abnormalities This severe clonal progression manifests clinically with severe bone marrow failure, worsening splenomegaly, systemic constitutional symptoms, and high risks of life-threatening infection, bleeding, and leukostasis

Pathophysiologically, it is defined by a failure of myeloid or lymphoid differentiation leading to an accumulation of 20% or more blast cells in the peripheral blood or bone marrow, or the presence of extramedullary blast proliferation

This severe clonal progression manifests clinically with severe bone marrow failure, worsening splenomegaly, systemic constitutional symptoms, and high risks of life-threatening infection, bleeding, and leukostasis
