NAD(P)H:quinone oxidoreductase 1 null genotype is not associated with pediatric de novo acute leukemia.

Background: NAD(P)H:quinone oxidoreductase1 (NQO1) is a two-electron reductase that detoxifies quinones derived from the oxidation of phenolic metabolites of benzene. Exposure to benzene metabolites increases the risk of hematotoxicity and leukemia. NQO1 enzyme activity protects the cells against metabolites of benzene.

Prognostic significance of the TEL-AML1 fusion gene in pediatric acute lymphoblastic leukemia in Turkey.

Purpose: The t(12;21) translocation is the most common reciprocal chromosomal rearrangement in pediatric acute lymphoblastic leukemia (ALL). This translocation fuses two genes, TEL and AML1, and results in the production of the TEL-AML1 fusion protein. The authors investigated the incidence and prognostic significance of the TEL-AML1 fusion gene in patients with ALL in Turkey.

Bacteremia in childhood cancer.

Infection-related mortality affects the overall survival rates of children who are receiving treatment for cancer. The leading cause of mortality is bacteremia and sepsis related to it in febrile neutropenic patients. All positive blood cultures of febrile neutropenic patients treated in the Department of Pediatric Hematology-Oncology, Cerrahpasa Medical School, between January 1995 and January 2001 were reviewed.
