High hyperdiploid acute lymphoblastic leukaemia
Prognosis for children is good with long term survival of 70%-80%; adults do less well although event free survival of 59% at 3 years has been reported; the good prognosis is thought to be related to leukaemic cell sensitivity to a number of anti-leukaemic drugs and the propensity of cells to respond by apoptosis; it is unclear why a proportion of patients fail to achieve long term remission bu...
متن کاملGenetic and regulatory mechanism of susceptibility to high-hyperdiploid acute lymphoblastic leukaemia at 10p21.2
Despite high-hyperdiploid acute lymphoblastic leukaemia (HD-ALL) being the most common subgroup of paediatric ALL, its aetiology remains unknown. Genome-wide association studies have demonstrated association at 10q21.2. Here, we sought to determine how this region influences HD-ALL risk. We impute genotypes across the locus, finding the single nucleotide polymorphism rs7090445 highly associated...
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 کاملGenetic landscape of high hyperdiploid childhood acute lymphoblastic leukemia.
High hyperdiploid acute lymphoblastic leukemia (ALL) is one of the most common malignancies in children. It is characterized by gain of chromosomes, typically +X, +4, +6, +10, +14, +17, +18, and +21,+21; little is known about additional genetic aberrations. Approximately 20% of the patients relapse; therefore it is clinically important to identify risk-stratifying markers. We used SNP array ana...
متن کاملBacktracking RAS mutations in high hyperdiploid childhood acute lymphoblastic leukemia.
High hyperdiploidy is the single largest subtype of childhood acute lymphoblastic leukemia (ALL) and is defined by the presence of 51-68 chromosomes in a karyotype. The 5 or more extra chromosomes characterizing this subtype are known to occur in a single mitotic event, prenatally. We screened for RAS mutations among 517 acute childhood leukemias (including 437 lymphocytic, of which 393 were B-...
