We report the results of ultrasound screening of the thyroid gland in 3,051 Belarus children 4-14 years of age exposed to radioactive fallout due to the Chernobyl accident. Screening was performed in 1990, 1993 and 1998. The study demonstrated that with time the prevalence of thyroid nodules in this contaminated region increased from 1.2% to 3.5%, mostly due to pathologically verified nodular goiter and non-verified small solid nodules and cysts. In contrast, the prevalence of thyroid carcinoma decreased from 0.6% in 1990 to 0.3% in 1993. We found 15 patients with carcinoma. On analysis of the ultrasound pattern of all carcinomas, we observed nodular and diffuse variants. Thus, we can conclude that systematic ultrasound screening is useful for the early detection of thyroid carcinoma in the population of Belarus exposed to radiation due to the Chernobyl accident.
我们报告了对3051名4至14岁白俄罗斯儿童甲状腺进行超声筛查的结果，这些儿童因切尔诺贝利事故暴露于放射性沉降物中。筛查分别于1990年、1993年和1998年进行。研究表明，随着时间的推移，该污染地区甲状腺结节的患病率从1.2%增至3.5%，主要原因是经病理证实的结节性甲状腺肿以及未经证实的小实性结节和囊肿。相比之下，甲状腺癌的患病率从1990年的0.6%降至1993年的0.3%。我们发现了15例癌症患者。在分析所有癌症的超声图像模式时，我们观察到了结节型和弥漫型。因此，我们可以得出结论，系统性超声筛查有助于在因切尔诺贝利事故而受辐射的白俄罗斯人群中早期发现甲状腺癌。
