Irradiations de la thyroïde et cancers thyroïdiens: Revue bibliographique critique

The large increase in the incidence of thyroid cancer among children who were mainly less than five years old at the time of the Chernobyl accident is still a major concern for endocrinologists and nuclear medicine physicians. Epidemiological studies have focused solely on iodine-131. However, past knowledge on thyroid irradiation (medical use of iodine-131, radioactive fallout on Marshall islands and the Nevada and Hanford site releases) as well as number of recent works (about low-dose irradiation) raise question on the role of other factors. It is here shown that post-Chernobyl thyroid irradiation is complex and that all factors (iodine-131, but also short lived isotopes of iodine and external irradiation) should be considered. Finally, one needs to think about some of the present medical uses of iodine-131 and especially to the treatment of hyperthyroidism in young subjects.
