The "post-Chernobyl" childhood leukemia study (ECLIS Study)

Numerous European cancer registries are working together to evaluate the current trends in the incidence of childhood leukemias after the Chernobyl accident. The study is coordinated by the International Agency for Research on Cancer. The primary objective is to establish whether the accident has resulted in an increase in the number of cases. The results will also allow an evaluation of the clusters which could be reported. According to the provisional estimations, the accident could lead to an increase of an average of 0.8% of the frequency of new cases in the European regions covered by the study. For the whole of Switzerland, this increase would correspond to 0.5 supplementary cases per year.
