The condition of thyroid was examined in 2188 Chernobyl clean-up workers residing in Latvia and a control group consisting of 1041 employees of the Ministry of Internal Affairs. Thyroid examinations included palpation, ultrasonography, selective scintigraphy and detection of the level of thyroid hormones in blood serum: TSH (thyroid-stimulating hormone), total T3 (triiodothyronine), and T4 (thyroxine). Thyroid pathology was registered in 394 Chernobyl clean-up workers. Of these cases, 28 patients with suspected thyroid cancer were operated, and morphological examinations revealed papillary adenocarcinoma (in 5 patients), follicular adenocarcinoma (2), nodular colloid goiter (16), toxic diffuse goiter (1), papillary-follicular adenoma (3), and chronic thyroiditis (1). It was determined that the thyroid pathology in the Chernobyl clean-up workers had a tendency to progress (27 cases in 1987 versus 394 cases in 1998 in total; and absence of thyroid cancer in 1987, compared with 7 cases in 1998); thyroid nodules increased twice (64 cases in 1997, compared with 126 cases in 1998).
