Filter by:The leukaemias are a heterogeneous group of blood cancers, Acute leukaemia (AL) is caused by malignant proliferation of blood cells arrested at an immature stage of development, They are very aggressive diseases that run a rapidly fatal course if not promptly diagnosed and appropriately treated. Misdiagnosis is very common with delay in diagnosis and prompt treatment being the causes of high morbidity and mortality in acute leukaemias. Although with the continuous improvement of clinical and laboratory diagnosis and treatment methods, the prognosis of AML has been significantly improved, but there are still about 70% of patients who cannot survive more than 5 years after diagnosis The activity of miRNAs in tumors is regulated by the same alterations affecting protein-coding genes, such as chromosomal rearrangements, genomic amplifications or deletions or mutations, abnormal transcriptional control, dysregulation of epigenetic changes and defects in the biogenesis machinery A typical chromosomal rearrangement is a chromosomal translocation, especially in hematological malignancies, in which it promotes tumor development and progression by the promoter exchange or by the creation of chimeric genes translated as fusion proteins. In Acute Myeloid Leukemia (AML) patients with myeloid/lymphoid leukemia gene (or mixed-lineage leukemia, MLL) rearrangement, by large-scale genome-wide microarray analysis, it was demonstrated that among 48 selected miRNAs, 47 of them are increased
The purpose of this study is to develop a highly sensitive method for assessing the functional activity of platelets for use in the differential diagnosis of thrombocytopenia and platelet defects.
This is a phase Ib/II clinical study that has two phases. In phase Ib, the safety evaluation of the extract of Petiveria alliacea (Esperanza) will be carried out in patients with metastatic gastrointestinal tumors (colon, pancreas, stomach, and biliary tract) and patients with newly diagnosed and relapsed acute leukemia. In phase IIb, the safety will continue to be evaluated, and the efficacy of the Esperanza extract will be explored in combination with chemotherapy in patients with metastatic gastrointestinal tumors (colon, pancreas, stomach, and biliary tract) with newly diagnosed acute leukemias and relapses.
This is a multi-phase, multi-center, single arm, prospective study designed to establish the safety and efficacy of human leukocyte antigen (HLA)-mismatched unrelated cryopreserved deceased donor bone marrow transplantation (BMT) with post-transplantation cyclophosphamide for patients with hematologic malignancies.
Because the anti-leukemic activity of busulfan, this dug is largely used in graft conditioning but in elderly and/or cormobid patienth an excess of toxicity is observed. This study focus on the possibility of significanty reducing this toxicity by customizing the doses of busulfan to individual PK parameters.
To study the immunophenotyping pattern of acute B lymphoblastic leukemia in south Egypt Cancer Institute iand its correlation with disease outcome
- To determine incidence of Expression of aberrant CD markers in acute leukemia in South Egypt . - Correlation between this expression and outcome of the patient.
Acute leukaemias (AL) are the first cause of cancer in children, with a majority of B acute lymphoblastic leukemia (ALL). Some of the processes causing leukemogenesis are already identified and well characterized in some AL subtypes such as translocation t (12; 21) of good prognosis in ALL. However, translocations are not sufficient to explain all the different processes of leukemogenesis, and other processes such as genetic / epigenetic mutations leading to oncogene activation / inhibition of tumor suppressor genes are the object research. Among the latter, mutations in tumor suppressor genes such as DCC (Deleted in Colorectal Cancer) have recently been identified in solid cancers, such as in hemopathies. This gene was subsequently characterized as encoding a "dependence receptor" specifically binding to its Netrin-1 ligand. Dependence receptors (RDs) are transmembrane receptors that cause cell death in the absence of their ligand. RD decreases tumor progression and overexpression of their ligands is observed in many cancers, such as B lymphomatous hemopathies in adults. Inhibition of the RD-ligand interaction constitutes a new and original therapeutic target in oncology. The aim of this study is to investigate whether RDs, in particular DCC, are expressed in acute leukemia cells at the time of diagnosis or relapse in patients aged 1 to 18 years, and then in these patients at the time of the remission balance. This research will be both qualitative and quantitative.
The aim of the present study is to detect the expression of TET 1 gene in patients with acute leukemia and its correlation with clinical and pathological criteria of the patients.
