Leukaemia risk associated with low-dose radiation
A partir des données de 9 cohortes (Canada, France, Japon, Suède, Royaume-Uni, Etats-Unis) incluant 262 573 participants ayant été exposés à des rayonnements ionisants à faible dose avant l'âge de 21 ans entre 1915 et 2004, cette étude analyse le risque de leucémie et de tumeur myéloïde (durée moyenne de suivi : 19,63 ans)
The association between radiation exposure in childhood and the subsequent risk of development of acute leukaemia (and other types of cancer) is well known.1 Awareness of this link has, over the past decade, led to a decrease in the use of CT testing in children, partly due to the dissemination of education and guidelines for reducing paediatric exposure to radiation in imaging.2,3 Therapy-related myeloid neoplasm, the development of either myelodysplastic syndromes or acute myeloid leukaemia following exposure to therapeutic radiotherapy treatment, is well described and has a poor prognosis.
