For people with relapsed AML, the only proven potentially curative therapy is a hematopoietic stem cell transplantif one has not already been performed.

Risk factors include smokingprevious chemotherapy or radiation therapymyelodysplastic syndromeand exposure to the chemical benzene.

International Journal of Hematology. APL is eminently curable, with well-documented treatment protocols. The goal of induction therapy is to achieve a complete remission by reducing the number of leukemic cells to an undetectable level; the goal of consolidation therapy is to eliminate any residual undetectable disease and achieve a cure.

In AML, though, a single myeloblast accumulates genetic changes which “freeze” the cell in its immature state and prevent differentiation. Wilhelm Ebstein introduced the term “acute leukemia” in to differentiate rapidly progressive and fatal leukemias from the more indolent chronic leukemias. It soon turned out that most t 8;21 q22;q22 cases were LMA subtype M2; only occasional leukaemias with this abnormality have been classified as subtype M1 or, even more rarely, subtype M4.

High amounts of ionizing radiation exposure can increase the risk of AML. A lack of normal white blood cell production makes people more susceptible to infections; while the leukemic cells themselves are derived from white blood cell precursors, they have no infection-fighting capacity.

DNA extracted from leukemic cells were compared to unaffected skin.

Editor e dois revisores externos. Retrieved 26 August As a pioneer in the use of the light microscope in pathology, Virchow was the first to describe the abnormal excess of white blood cells in people with the clinical syndrome described by Velpeau and Bennett. Essential thrombocytosis Acute megakaryoblastic leukemia. Most signs and symptoms of AML are caused by the replacement of normal blood cells with leukemic cells. In straightforward cases, the presence of certain morphologic features such as Auer rods or specific flow cytometry results can distinguish AML from other leukemias; however, in the absence of such features, diagnosis may be more difficult.

Multiple cases of AML developing in a family at a rate higher than predicted by chance alone have been reported. Gesammelte Abhandlungen zur Wissenschaftlichen Medizin in German. Enlargement of the spleen may occur in AML, but it is typically mild and asymptomatic.

Retrieved 10 May The best postremission therapy for intermediate-risk AML normal cytogenetics or cytogenetic changes not falling into good-risk or high-risk groups is less clear and depends on the specific situation, including the age and overall health of the person, the person’s values, and whether a suitable stem cell donor is available.

Because acute promyelocytic leukemia APL has the highest curability and requires a unique form of treatment, it is important to quickly establish or exclude the diagnosis of this subtype of leukemia.

A hereditary risk for AML appears to exist.

AML which arises from a pre-existing myelodysplastic syndrome MDS or myeloproliferative disease so-called secondary AML has a worse prognosisas does treatment-related AML arising after chemotherapy for another previous malignancy. Since high complete remission rates as well as their duration 6 have generally been found in AML subtype M2 patients with t 8;21 q22;q22 treated with conventional chemotherapy regimens, this translocation has been considered as nieloide prognostic indicator of favourable outcomes.

The symptoms of AML are, mieliide turn, often due to the low numbers of these normal blood elements. Occupational chemical exposure to benzene and other aromatic organic solvents is controversial as a cause of AML. Acute myeloid leukemia is a relatively rare cancer. Identification of a translocation with quinacrine fluorescence in a patient with acute leukemia.
