Infant Acute Lymphoblastic Leukemia
نویسنده
چکیده
Acute lymphoblastic leukemia (ALL) in infants under 12 months of age accounts for about 4% of childhood ALL and differs from ALL in older children with respect to immunophenotypic, cytogenetic and molecular genetic features. In contrast to the predominance of male sex in older children with ALL, there is a slight predominance of girls in infant ALL (1). In infant leukemia, all necessary genetic leukemogenic events may have occurred in utero, illustrated by the very early onset of infant ALL and the high rate of concordance of leukemia in monozygotic twins if one of the children developed leukemia during infancy. MLL-AF4 fusion sequences have been detected in the Guthrie cards from children who were diagnosed with ALL in infancy (2).

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 کاملInfluences of Genetic Abnormality on the Risk of Acute Lymphoblastic Leukemia
Recent studies have provided evidence that common genetic variations could account for a proportion of leukemia in adult or children. To evaluate the contribution of candidate gene association studies to the understanding of genetic susceptibility to acute lymphoblastic leukemia we conducted a systematic review from published studies. The polymorphisms of genes encoding carcinogen-metabolizi...

Aim: Leukemia targets are one of the most common childhood malignancies. Epstein-Barr virus is a tumorigenic virus of the herpes family of viruses and causes primary infection in young children. The aim of this study was to evaluate the increase in NFKB expression following EBV virus and its contribution to the half-life of EBV-positive acute lymphoblastic leukemia patients. Materials and Meth...
