Simultaneous Neuroblastoma and Acute Lymphoblastic Leukemia in an Infant

Infant Acute Lymphoblastic Leukemia

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...

simultaneous occurrence of advanced neuroblastoma and acute lymphoblastic leukemia: a case report

neuroblastoma is the most common extracranial solid tumor in children. the co- occurrence of neuroblastoma and acute lymphoblastic leukemia is rare. we report a rare case of advanced-stage neuroblastoma in a 3.5-year-old girl that was accompanied by acute lymphoblastic leukemia following treatment. her leukemia may have been due to chemotherapy (secondary leukemia) or may have been de novo.

NUDT15 genetic variants and 6-mercaptopurine intolerance in pediatric acute lymphoblastic leukemia: an updated review

Acute lymphoblastic leukemia (ALL) accounts for nearly 30% of pediatric cancers. The maintenance treatment for ALL comprises daily oral 6-mercaptopurine (6-MP) and weekly methotrexate (MTX). 6-MP is a purine analog that can significantly improve the long-term survival of ALL patients. Despite more than 90% of 5-year survival of childhood ALL in developed countries, treatment interruption due to...

Bone Scintigraphy in Acute Lymphoblastic Leukemia

Leukemia is the most common childhood cancer and accounts for 30-40% of all malignancies. A retrospective review  was performed of the hospital records of 9 children, 6 boys and 3 girls, aged  from 2.5 to 15 years with ALL initially referred to Nemazee hospital Nuclear medicine center for whole body bone scanning between 2000 and 2002. Bone marrow pathology established ALL (L1) in two and ALL (...

Association of Acute Lymphoblastic Leukemia and MDR1 Gene Polymorphism in an Ethnic Iranian Population

Background: The frequency of the multi-drug resistance 1 (MDR1) gene C3435T polymorphism differs in various ethnical populations such as Asian, African, and Caucasians populations. A silent C3435T polymorphism in exon 26 of MDR1 has been reported to be associated with a decreased expression of P-gp in TT genotypes carriers compared with CC genotypes carriers. Materials and Methods: To evaluate ...
