Epidemiological aspects of the incidence of thyroid cancer in the Russian Federation

The results of an analysis of the incidence of thyroid cancer (thyroid cancer) in the Russian Federation (2008−2018) are presented. With increasing age, the incidence of thyroid cancer increases. Dominated by people aged 55 years and above (52.9%). Over the 10-year period (2008−2018), the increase in the “rough” indicator of the incidence of thyroid cancer was 49.03%, the standardized − 43.5%. The prevalence of thyroid cancer among the population of the Russian Federation in 2018 amounted to 114.1 per 100,000 population, which is 52.5% higher than in 2008 (74.8). This is due to several reasons: the demographic aging of the population, an increase in the incidence rate, and an improvement in the detection of the disease among the population (from 17.4% in 2008 to 34.3% in 2018). There was an increase in the share of thyroid cancer patients registered in oncological institutions of the Russian Federation for 5 years or more from the moment of diagnosis (from 61.6% to 68.8%, respectively), and the index of accumulation of patients with thyroid cancer (from 12.4 to 13.9 respectively). In the cohort of thyroid cancer patients, identified actively, the proportion of patients with a tumor process of stage I−II was 77.7%, and with a running tumor process (stage III−IV) — 21%. There is a differentiation of the territories of the Russian Federation both in terms of early detection and morphological verification of thyroid cancer, and the volume of radical treatment and the use of various methods for its implementation.
