PREVALENCE, INCIDENCE AND MORTALITY OF THYROID CANCER IN KAZAKHSTAN: DATA FROM UNIFIED NATIONAL ELECTRONIC HEALTH SYSTEM 2014-2021

Abstract

Although a rare type of cancer overall, thyroid cancer is one of the most common endocrine malignancies. According to global studies, its prevalence has been increasing worldwide and continues to grow. Although there are global epidemiological studies on thyroid cancer that involved many regions, there is limited data on the epidemiology of thyroid cancer in Central Asian countries, including Kazakhstan. This project was done to provide information on demographic characteristics of diagnosed patients, determine prevalence, incidence and mortality rates of thyroid cancer in Kazakhstan and conduct survival analysis for such patients. According to the data provided from the Unified National Electronic Health System, in total, 4,877 cases of thyroid cancer have been identified during the period from 2014 to 2021 in Kazakhstan. Based on the results, most of the diagnosed patients throughout the given period were females. The highest incidence and prevalence rates were found in the age group of 51-70 years old while the highest mortality rate was among patients older than 70. Increasing age and male sex were reported as the major predictors of mortality among thyroid cancer patients.
