Acute myeloid leukemia (AML) is an aggressive malignancy with a relapse rate approaching 50%, despite aggressive chemotherapy. New therapies for AML are targeted at signal transduction pathways known to support blast survival, such as the Stat3 pathway. Aberrant activation of Stat3 has been demonstrated in many different malignancies, including AML, and this finding is frequently associated wit...

OBJECTIVE Leukemia is the most common pediatric malignancy and a major cause of morbidity and mortality in children. Among all subtypes, a lack of consensus exists regarding the diagnosis and treatment of acute myeloid leukemia (AML). Patient survival rates have remained modest for the past three decades in AML. Recently, targeted therapy has emerged as a promising treatment. DATA SOURCES We ...

Chromosomal abnormalities are an attractive avenue for the screening of various disorders especially related to carcinogens like acute myeloid leukemia (AML). The cytogenetic findings like Karyotypic patterns are common in pediatric patients. On the other hand, monosomal karyotype (MK) and complex karyotype (CK) are more common in older patients. Further, recent studies have revealed direct pro...

The aim of this study was to investigate the role of microRNA-335 (miR-335) in determining the treatment response and prognosis in adult acute myeloid leukemia (AML) patients receiving the cytarabine (Ara-C)-based chemotherapy.A total of 204 adult AML patients were collected. The miR-335 levels in serum and bone marrow samples from these patients were determined. All patients received Ara-C-bas...

Among various laboratory and clinical features megakaryocytopoiesis and platelet (PLT) counts have been previously insufficiently evaluated for their prognostic significance in acute myelogenous leukaemia (AML). We studied several clinical and laboratory features of 108 first diagnosed AML patients in relation with their prognosis. Patients with favourable prognostic features were excluded from...

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:</...

In acute myeloid leukaemia (AML) t(8;16)(p11;p13)/MYST3–CREBBP is a very rare abnormality. Previous small series suggested poor outcome. We report on 59 patients with t(8;16) within an international, collaborative study. Median age was 52 (range: 16–75) years. AML de novo in 58%, therapy-related (t-AML) 37% and secondary after myelodysplastic syndrome (s-AML) 5%. Cytogenetics revealed complex k...

Background: The glutathione S-transferase (GST) family of metabolising enzymes plays an important role in the detoxification of mutagens and carcinogens. The expression of many of these cancer susceptibility enzymes is genetically polymorphic. An increased frequency of GST-null genotypes has been associated with several malignancies. Objective: To investigate the rate of GSTT1 and GSTM1 null ge...

background: global death toll of acute leukemia (al), as a heterogeneous group of hematopoietic malignancies, is rather high, i.e. almost 74% of 300,000 new cases die every year. this reflects a poor prognosis of this malignancy in most parts of the world, where contemporary and rather complex remedies are not available. there are a few well documented reports about the epidemiologic features o...
