Radiation exposure and the risk of pediatric thyroid cancer.

Miyakawa M - Clin Pediatr Endocrinol (2014)

Bottom Line: It has been more than three years since the unprecedentedly massive earthquake and tsunami struck eastern Japan on March 11, 2011, and the large accident occurred at the Fukushima Daiichi Nuclear Power Plant.As of September 2013, 59 children had been diagnosed with thyroid cancer by fine-needle aspiration cytology, and 34 children had been treated surgically and ultimately diagnosed with papillary thyroid cancer.Here, I would like to describe the characteristics of pediatric thyroid cancer and typical thyroid images obtained by ultrasonography.

ABSTRACT
It has been more than three years since the unprecedentedly massive earthquake and tsunami struck eastern Japan on March 11, 2011, and the large accident occurred at the Fukushima Daiichi Nuclear Power Plant. To investigate the influence of radiation exposure, thyroid ultrasonography has been provided preliminarily for 360,000 children who lived in Fukushima Prefecture at the time of the accident. As of September 2013, 59 children had been diagnosed with thyroid cancer by fine-needle aspiration cytology, and 34 children had been treated surgically and ultimately diagnosed with papillary thyroid cancer. Here, I would like to describe the characteristics of pediatric thyroid cancer and typical thyroid images obtained by ultrasonography.

Mentions: In the Chernobyl Nuclear Power Plant accident, which occurred in 1986, a vast amount ofiodine-131 spread over a few hundred square kilometers. Children in the region consumed milkwith a high concentration of iodine-131 (17–450 times higher than the regulatory dose limitin Japan), causing a distinct increase in the number of pediatric thyroid cancer cases. InBelarus, the number of pediatric thyroid cancer cases for 11 yr preceding the accident was7, but in the 11 yr following the accident, the number of thyroid cancer cases increased to508, which is 73 times higher than before the accident (2). In addition, it is reported that 97.6% of children who had thyroid cancer wereunder the age of 10 (Fig. 2Fig. 2.
