Abstract
Epidemiological studies have associated the exposure to permethrin and malathion with increased risk of leukemia and lymphoma. The aim of this study was to evaluate whether in vitro exposure to permethrin and malathion induces aberrations in genes involved in the etiology of these hematological malignancies. Genetic abnormalities in the IGH, KMT2A (MLL), ETV6 and RUNX1 genes, and aneuploidy induced by the in vitro exposure to permethrin and malathion (200μM, 24h), were analyzed by FISH in peripheral blood mononuclear cells (PBMCs). The gene fusions IGH-BCL2, KMT2A-AFF1 and ETV6-RUNX1 were further analyzed with nested RT-PCR in PBMCs, and in K562 cells exposed to acute and chronic treatments (0.1μM, 24h or every third day for two weeks) of insecticides. FISH analysis revealed that permethrin induces aneuploidy and structural alterations in IGH and KMT2A genes, and malathion induces breaks in KMT2A. RT-PCR detected ETV6-RUNX1 fusion in PBMCs acutely exposed to permethrin. Permethrin also induced ETV6-RUNX1 and IGH-BCL2 fusions in K562 cells, and malathion induced KMT2A-AFF1 and ETV6-RUNX1 fusions. Overall, we identified that both insecticides induce breaks and fusions in the studied genes, and permethrin induces aneuploidy. This study presents evidence of damage in cancer genes caused by these insecticides.

Abstract
The object was to determine the role ABMT in children with advanced cancer Those included had failed to respond to conventional treatment with 4 different ablative chemotherapy regimens. Bone marrow stem cells were identified with CD34. Cellular viability was determined after the bone marrow extraction and before the infusion. Fifteen patients were included, whose ages ranged from 1 to 13 years old with a median of 7. Six had acute leukemia, 6 with primitive neuroectodermic tumors, and 3 with other tumors. The median disease-free survival for the whole group was of 2 months, range of 1 to 29 months and SD of 10.1. A total of 6 children are alive (40%) and without evidence of tumor activity from 1 to 29 months. The disease-free survival rate for these group was of 19.1 months, with an SD of 7.9 months.
