Clinico-morphological characteristic of papillary thyroidal carcinomas in patients, born before and after of the Chornobyl AES disaster
Objective. To study the thyroidal papillary carcinomas rate with various characteristics, depending on the patients’ age, taking into account their birthdate - before and after disaster on Chornobyl AES.
Маterials and methods. Retrospective investigation concerning 4956 patients, оperated for papillary thyroidal carcinoma in 1995 - 2014 yrs.
Results. In the patients, ageing up to 18 years old, comparing with adult patients, and not dependent on their birthdate, most frequent tumors were 21 - 40 mm in size, categories N1ab and М1, with tumoral invasion into the capsule, іntra- or extrathyroidal invasion were observed. In children and adolescents, born after disaster, less often, than in children and adolescents, born before the disaster, multifocal carcinomas and carcinomas of category N1ab were observed.
Conclusion. Papillary carcinomas in children and adolescents, who were born before and after disaster on Chornobyl AES, are more aggressive, than papillary carcinomas in adult patients, but by their clinical characteristics are similar, excluding lesser rate of multifocal carcinomas and carcinomas of category N1ab.
