Expertise of occupational thyroid cancer in patients dealing with ionizing emission sources

The research is based on the analysis of 14 case histories of patients with thyroid tumors. Twelve patients out of 14 were diagnosed with thyroid cancer, 2 - with mixed and multinodular goiter. All patients underwent surgery: 6 - hemistrumectomy, 8 - subtotal thyroid resection with lymphodissection. The histological examination showed papillary carcinoma in 11 patients, follicular carcinoma in 1 patient. Among the patients with thyroid cancer, 5 had stage I, 6 - stage II, 1 - stage III. According to the Guidelines and Procedures Letter of the Central Medical Advisory Committee of SI Grigoriev Institute for Medical Radiology of NAMS of Ukraine No 20/1377 dated 22/12/2010, the Central Dispensary Committee diagnosed occupational cancer in 5 patients with thyroid cancer exposed to ionizing emission from 2011 to 2017. For the cases observed in patients of this category, whose case histories were considered before 2011, the diagnosis of occupational cancer was not established due to absence of this diagnosis in the Occupational Diseases List according to Resolution of the Cabinet of Ministers of Ukraine No 1662 dated 08/11/2000. A small number of case histories of patients with thyroid neoplasms who deals with ionizing emission sources has to be estimated. The current issue is further improvement of diagnostic criteria of occupational cancer in workers of this category.
