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 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 کاملOutcome heterogeneity in childhood high-hyperdiploid acute lymphoblastic leukemia.
High hyperdiploidy (HeH) (51 to 65 chromosomes) is found in one third of children with acute lymphoblastic leukemia and is associated with a good prognosis. Cytogenetic features may further refine this prognosis and identify patients with a poor outcome. We examined the effect of sex, age, individual trisomies, modal number, and structural abnormalities on survival among 700 children with HeH. ...
متن کاملDetection Of 11q23 Gene Rearrangement In Children With Acute Lymphoblastic Leukemia And Its Association With Demographic Data and Response To Initial Chemotherapy On The Seventh Day Of Induction
Background: Acute lymphoblastic leukemia (ALL) is the most common form of childhood cancer leading to cancer-related death in children. Most infants with ALL harbor recurring structural chromosomal rearrangements that are important initiating events in leukemogenesis but are insufficient to explain the biology and heterogeneity of the disease. Mixed-lineage leukemia-rearrangement (MLL-rearrange...
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...
