A sharp increase in the incidence of pediatric thyroid papillary cancer was documented after
the Chernobyl power plant explosion. An increased prevalence of rearrangements of the
RET protooncogene (RET/PTC rearrangements) has been reported in Belarussian post-
Chernobyl papillary carcinomas arising between 1990 and 1995. We analyzed 67 post-
Chernobyl pediatric papillary carcinomas arising in 1995–1997 for RET/PTC activation: 28
were from Ukraine and 39 were from Belarus. The study, conducted by a combined …
