Household Exposure to Pesticides and Risk of Childhood Hematopoietic Malignancies: The ESCALE Study (SFCE)
International audienceOBJECTIVES: We investigated the role of household exposure to pesticides in the etiology of childhood hematopoietic malignancies. METHODS: The national registry-based case-control study ESCALE (Etude sur les cancers de l'enfant) was carried out in France over the period 2003-2004. Population controls were frequency matched with the cases on age and sex. Maternal household use of pesticides during pregnancy and paternal use during pregnancy or childhood were reported by the mothers in a structured telephone questionnaire. Insecticides (used at home, on pets, or for garden crops), herbicides, and fungicides were distinguished. We estimated odds ratios (ORs) using unconditional regression models closely adjusting for age, sex, degree of urbanization, and type of housing (flat or house). RESULTS: We included a total of 764 cases of acute leukemia (AL), 130 of Hodgkin lymphoma (HL), 166 of non-Hodgkin lymphoma (NHL), and 1,681 controls. Insecticide use during pregnancy was significantly associated with childhood AL [OR = 2.1; 95% confidence interval (CI), 1.7-2.5], both lymphoblastic and myeloblastic, NHL (OR = 1.8; 95% CI, 1.3-2.6), mainly for Burkitt lymphoma (OR = 2.7; 95% CI, 1.6-4.5), and mixed-cell HL (OR = 4.1; 95% CI, 1.4-11.8), but not nodular sclerosis HL (OR = 1.1; 95% CI, 0.6-1.9). Paternal household use of pesticides was also related to AL (OR = 1.5; 95% CI, 1.2-1.8) and NHL (OR = 1.7; 95% CI, 1.2-2.6); but for AL the relationships did not remain after adjustment for maternal pesticide use during pregnancy. CONCLUSION: The study findings strengthen the hypothesis that domestic use of pesticides may play a role in the etiology of childhood hematopoietic malignancies. The consistency of the findings with those of previous studies on AL raises the question of the advisability of preventing pesticide use by pregnant women
Parental Tobacco Smoking and Acute Myeloid Leukemia:The Childhood Leukemia International Consortium
The association between tobacco smoke and acute myeloid leukemia (AML) is well established in adults but not in children. Individual-level data on parental cigarette smoking were obtained from 12 case-control studies from the Childhood Leukemia International Consortium (CLIC, 1974-2012), including 1,330 AML cases diagnosed at age <15 years and 13,169 controls. We conducted pooled analyses of CLIC studies, as well as meta-analyses of CLIC and non-CLIC studies. Overall, maternal smoking before, during, or after pregnancy was not associated with childhood AML; there was a suggestion, however, that smoking during pregnancy was associated with an increased risk in Hispanics (odds ratio = 2.08, 95% confidence interval (CI): 1.20, 3.61) but not in other ethnic groups. By contrast, the odds ratios for paternal lifetime smoking were 1.34 (95% CI: 1.11, 1.62) and 1.18 (95% CI: 0.92, 1.51) in pooled and meta-analyses, respectively. Overall, increased risks from 1.2- to 1.3-fold were observed for pre- and postnatal smoking (P < 0.05), with higher risks reported for heavy smokers. Associations with paternal smoking varied by histological type. Our analyses suggest an association between paternal smoking and childhood AML. The association with maternal smoking appears limited to Hispanic children, raising questions about ethnic differences in tobacco-related exposures and biological mechanisms, as well as study-specific biases
Antécédents familiaux de cancer et risque d hémopathie maligne de l enfant
Objectif : Nous avons Ă©tudiĂ© l influence des antĂ©cĂ©dents familiaux de cancer sur la survenue des leucĂ©mies aiguĂ«s (LA), lymphomes de Hodgkin (LH) et lymphomes non hodgkiniens (LNH) de l enfant Ă partir des donnĂ©es de l enquĂȘte ESCALE. MatĂ©riel et mĂ©thodes : ESCALE est une enquĂȘte cas-tĂ©moin nationale rĂ©alisĂ©e en population gĂ©nĂ©rale sur la pĂ©riode 2003-2004. L Ă©chantillon comportait 1072 cas incidents d hĂ©mopathie maligne (779 LA, 130 LH et 163 LNH) et 1681 tĂ©moins de moins de 15 ans. L Ă©chantillonnage a Ă©tĂ© stratifiĂ© sur l Ăąge et le sexe. Les antĂ©cĂ©dents familiaux de cancer aux premier et deuxiĂšme degrĂ©s Ă©taient recueillis auprĂšs des mĂšres Ă l aide d un questionnaire tĂ©lĂ©phonique standardisĂ©, identique pour les cas et les tĂ©moins. Les odds ratios (OR) ont Ă©tĂ© estimĂ©s Ă l aide de modĂšles de rĂ©gression logistique non conditionnelle. RĂ©sultats : Contrairement aux LA, les LH et les LNH Ă©taient associĂ©s Ă la prĂ©sence d antĂ©cĂ©dents familiaux de cancer (LA : OR=1,0 [0,9-1,2] ; LH : OR=1,5 [1,0-2,2] ; LNH : OR=1,8 [1,3-2,6]), avec des OR plus Ă©levĂ©s quand au moins deux apparentĂ©s avaient eu un cancer ou quand un des antĂ©cĂ©dents cancers Ă©tait survenu avant l Ăąge de 46 ans. Par ailleurs, seuls les LH Ă©taient liĂ©s significativement aux antĂ©cĂ©dents familiaux d hĂ©mopathie maligne (LA : OR=1,0 [0,6-1,5] ; LH : OR=2,0 [1,0-3,8] ; LNH : OR=1,0 [0,5-2,0]), et en particulier aux antĂ©cĂ©dents de LH (OR=5,4 [1,3-22]). Conclusion : Nos rĂ©sultats apportent des arguments en faveur d'une prĂ©disposition familiale aux lymphomes de l'enfant. En revanche, ils ne soutiennent pas l'hypothĂšse d'une telle prĂ©disposition dans les leucĂ©miesPARIS6-Bibl.PitiĂ©-SalpĂȘtrie (751132101) / SudocPARIS-BIUM (751062103) / SudocSudocFranceF

Facteurs de risque des cancers de lâenfant : de la conception Ă la survenue des cancers: Exposition rĂ©sidentielle aux facteurs de lâenvironnement gĂ©nĂ©ral : de la conception Ă la survenue des cancers de lâenfant. Etude de faisabilitĂ©
National audienceLes cancers se prĂ©sentent de façon trĂšs diffĂ©rente chez lâenfant et chez lâadulte. Beaucoup plus rares chez lâenfant, ils nâen demeurent pas moins un problĂšme important de santĂ© publique et constituent la deuxiĂšme cause de mortalitĂ© infantile aprĂšs les accidents. Certains facteurs de risques ont Ă©tĂ© identifiĂ©s pour certains cancers : facteurs infectieux, facteurs de susceptibilitĂ© gĂ©nĂ©tique, dĂ©ficits immunitaires... On soupçonne Ă©galement des facteurs environnementaux. Le projet de recherche GĂOCAP-PAST vise Ă chercher des corrĂ©lations entre les cancers pĂ©diatriques et des expositions rĂ©sidentielles Ă des facteurs de risques suspectĂ©s : notamment les radiations ionisantes dâorigine naturelle, la proximitĂ© de sites nuclĂ©aires, le trafic routier, la proximitĂ© de lignes Ă haute tension, les expositions aux pesticides liĂ©es aux activitĂ©s agricoles
LeucĂ©mies aiguĂ«s de lâenfant : interactions gĂšne-environnement: Interactions gĂšneâenvironnement et leucĂ©mies aiguĂ«s de lâenfant : analyse de lâenquĂȘte ESTELLE
La leucĂ©mie est un cancer qui atteint les cellules souches sanguines. La frĂ©quence des leucĂ©mies est relativement faible mais, chez lâenfant, câest le type de cancer le plus frĂ©quent. Le dĂ©veloppement de la maladie est multi-Ă©tapes ; depuis vingt ans, les preuves dâune initiation prĂ©natale des leucĂ©mies aiguĂ«s de lâenfant se sont accumulĂ©es. Les facteurs qui induisent la formation dâune cellule leucĂ©mique sont vraisemblablement multiples : facteurs gĂ©nĂ©tiques et/ou environnementaux. TrĂšs peu dâentre eux sont Ă©tablis comme facteurs de risque certains. La dĂ©couverte rĂ©cente des polymorphismes liĂ©s au risque de leucĂ©mies aiguĂ«s de lâenfant modifie profondĂ©ment le champ de la recherche sur les causes de ces maladies. Certains des facteurs de risque environnementaux suspectĂ©s pourraient modifier l'effet de ces gĂšnes, et inversement, ces gĂšnes pourraient influer sur l'effet de ces facteurs environnementaux au niveau de l'organisme
Les risques de cancer de l'enfant
Pour comprendre le rĂŽle de lâexposition rĂ©sidentielle dans la survenue de cancers infantiles, il importe de pouvoir localiser les adresses des enfants concernĂ©s â ce qui est possible Ă partir des registres nationaux des cancers de lâenfant. Ce type dâanalyse fournira des informations utiles Ă la recherche des causes des leucĂ©mies de lâenfant et pourra contribuer, Ă long terme, Ă leur prĂ©vention
