PROGNOSTIC VALUE OF MYELOID ANTIGEN EXPRESSION IN ACUTE LYMPHOBLASTIC LEUKEMIA
Expression of cell surface molecules associated with lymphoid and myeloid lineage differentiation on the blasts of 53 patients with acute lymphoblastic leukemia (ALL) was investigated. 1.9% of cases were only HLA"7DR+ 7.6% were HLA-DR+, CDI9+ 22.6% were HLA-DR+, CDI9+, CDI0+ 30.2% were HLADR+, CDI9+, CDlO±, CD20+ and 37.7% were HLA-DR±, CD7+, CD5±. Aberrant expression of one or more myeloi...
متن کاملAcute myeloid leukemia and acute promyelocytic leukemia.
The therapeutic approach to the patient with acute myeloid leukemia (AML) currently evolves toward new frontiers. This is particularly apparent from the entree of high-throughput diagnostic technologies and the identification of prognostic and therapeutic targets, the introduction of therapies in genetically defined subgroups of AML, as well as the influx of investigational approaches and novel...
متن کاملEvaluation of the CD123 Expression and FLT3 Gene Mutations in Patients with Acute Myeloid Leukemia
Background and Objective: Identification of cytogenetic and molecular changes plays an important role in acute myeloid leukemia (AML) patients. Thus, they are used in classification, prognosis and treatment of the disease. The CD123 expression and FLT3 gene mutations are also the variations that may assist in prognosis and treatment of patients with AML.Methods:</...
متن کاملTargeted therapy for a subset of acute myeloid leukemias that lack expression of aldehyde dehydrogenase 1A1
Aldehyde dehydrogenase 1A1 (ALDH1A1) activity is high in hematopoietic stem cells and functions in part to protect stem cells from reactive aldehydes and other toxic compounds. In contrast, we found that approximately 25% of all acute myeloid leukemias expressed low or undetectable levels of ALDH1A1 and that this ALDH1A1- subset of leukemias correlates with good prognosis cytogenetics. ALDH1A1-...
متن کاملHematopathology / LEUKEMIAS RESEMBLING ACUTE PROMYELOCYTIC LEUKEMIA, MICROGRANULAR VARIANT Leukemias Resembling Acute Promyelocytic Leukemia, Microgranular Variant
Acute promyelocytic leukemia (APL) should be distinguished from other subtypes of acute myeloid leukemia (AML) because of the increased risk of disseminated intravascular coagulation (DIC) and its response to arsenic compounds and retinoids. Some cases of AML seem morphologically similar to the microgranular variant of APL (French-AmericanBritish [FAB] AML-M3v) but lack the t(15;17). We evaluat...
