Background: Acute myelogenous leukemia (AML) is a malignant disease of the bone marrow in which hematopoietic precursors are arrested in an early stage of development.
Most AML subtypes are distinguished from other related blood disorders by the presence of more than 20% blasts in the bone marrow.
AML is more common in whites than in other populations.

 Gingival Hyperplasia Complicating Acute Myelomonocytic Leukemia
Given our concern about possible acute leukemia, which was substantiated by a complete blood count with differential, a bone marrow biopsy was performed and the nodule was excised.
Gingival hyperplasia is most commonly seen with the AML subtypes acute monocytic leukemia (M5) (66.7%), acute myelomonocytic leukemia (M4) (18.5%), and acute myelocytic leukemia (M1, M2) (3.7%).
Leukemia cell gingival infiltrate is not observed in edentulous individuals, suggesting that local irritation and trauma associated with the presence of teeth may play a role in the pathogenesis of this abnormality.

 Adult acute myeloid leukemia
Leukemias that express the progenitor cell antigen CD34 and/or the P-glycoprotein (MDR1 gene product) have an inferior outcome.[6-8] Expression of the bcl-2 oncoprotein, which inhibits programmed cell death, has been shown to predict poor survival.[9] Cytogenetic analysis provides some of the strongest prognostic information available and is helpful in patients with newly diagnosed AML.
Acute myeloid leukemia (AML) is classified morphologically according to the French-American-British criteria by the degree of differentiation along different cell lines and the extent of cell maturation.[1-3]
Adult AML in remission is defined as a normal peripheral blood cell count and normocellular marrow with less than 5% blasts in the marrow, and no signs or symptoms of the disease.

For example, the cumulative incidence of acute leukemia in patients with breast cancer who were treated with doxorubicin and cyclophosphamide as adjuvant therapy was 0.2-1.0% at 5 years.
Acute promyelocytic leukemia (APL), also known as M3, is the most common subtype of AML associated with DIC.
However, the median age of patients with AML is 65 years; therefore, only a small percentage of patients with AML are candidates for such aggressive therapy.

These cytogenetic subgroups predict clinical outcome in elderly patients with AML as well as in younger patients.[10] The fusion genes formed in t(8;21) and inv(16) can be detected by reverse-transcriptase polymerase chain reaction (RT-PCR), which will indicate the presence of these genetic alterations in some patients in whom standard cytogenetics was technically inadequate.

However, even with allogeneic stem cell transplantation, the outcome for high-risk patients is poor (5-year disease-free survival of 8% to 30% for patients with treatment-related leukemia or myelodysplasia).[33] The efficacy of autologous stem cell transplantation in the poor-risk group has not been reported to date but is the subject of active clinical trials.

 Myeloperoxidase in acute myelomonocytic leukemia   (Site not responding. Last check: 2007-10-29)
The FAB investigators recommend two cytochemical tests for the diagnosis of all new cases of acute leukemia.
These recommended tests are (1) myeloperoxidase activity or Sudan fl staining, which are positive in nearly all cases of myelocytic leukemia, and (2) esterase activity for identifying monocytes.
The latter assay recommended is naphthol AS-D acetate substrate and fast blue or fast blue BB salt for coupling the liberated product to form a colored compound.
