Presenting Clinical and Laboratory Data of Childhood Acute Lymphoblastic Leukemia
Abstract Background Leukemia is the most prevalent childhood cancer and Acute Lymphoblastic Leukemia (ALL) constitutes 75% of all cases. The most frequent presenting symptoms are fever, weight loss and pallor. Early detection of clinical symptoms positively affects timely diagnosis. The objectives of the present study were to assess frequency of presenting symptoms, laboratory data, immune ph...
متن کاملChildhood Acute Lymphoblastic Leukemia.
The cure rate for childhood acute lymphoblastic leukemia (ALL) now exceeds 70%. This success has been achieved in part by improvements in the biologic characterization of newly diagnosed patients. Modern treatment protocols rely on this information to tailor therapy to a patient's risk of relapse. Patients with favorable genetic features, such as hyperdiploidy or the TEL-AML1 fusion, can be tre...
متن کاملChildhood Acute Lymphoblastic Leukemia
Acute lymphoblastic leukemia (ALL) is recognized as a fast-developing cancer originated from blood-progenitor cells. Blasts cells are immature cells which generate white blood cells (leukocytes), and it is the malignancy of the blast cells which lead to leukemias. The bone marrow is gradually filled up with these blasts and as a result, the production of healthy blood cells will be damaged. Mal...
متن کاملDiversity of T-cell receptor Gene Rearrangements in South Indian Patients with Common Acute Lymphoblastic Leukemia
Background: Precursor B-Acute Lymphoblastic Leukemia (precursor B-ALL) oc-curs due to the uncontrolled proliferation of B-lymphoid precursors arrested at a par-ticular stage of B-cell development. Precursor-B-ALL is classified mainly into pro-B-ALL, common-ALL and pre-B-ALL. The Common Acute Lymphoblastic Antigen CD10 is the marker for common-ALL. Objective: This study was aimed to examine the ...
متن کاملClonal, nonconstitutional rearrangements of the MLL gene in infant twins with acute lymphoblastic leukemia: in utero chromosome rearrangement of 11q23.
Rearrangements of chromosome band 11q23 are common in infant leukemias, comprising more than 70% of the observed chromosome abnormalities in children less than 1 year of age. The MLL gene, which is located at the 11q23 breakpoint in infant, childhood, and adult acute leukemias, has been cloned and has homology to the Drosophila trithorax gene. The breakpoints in MLL are restricted to an 8.3-kil...
