Age and gender patterns of thyroid cancer incidence in Ukraine depending on thyroid radiation doses from radioactive iodine exposure after the Chornobyl NPP accident.

摘要: UNLABELLED The objective of this study was to investigate the thyroid cancer incidence in a whole territory Ukraine and clear up its age gender patterns depending on average regional (oblast) doses from radioactive iodine due Chornobyl accident. MATERIALS AND METHODS. On basis accumulated geographical regions with low high were identified for comparative analysis performance. Methods descriptive epidemiology used. RESULTS level dynamics analyzed different groups (both attained at moment accident). Results confirmed radiation excess individuals who children adolescents 1986. Some observed elder too. Especial situation female group 40-49 accident i.e. age-specific rates significantly higher "high exposure" comparing "low ones during all years observation within 1989-2009. CONCLUSIONS A probable suggested not only but also adult groups. In less expressed manifested after longer period time. origin phenomenon is unclear now. Hypothesis combined effect natural changing hormonal status should be checked future studies.
