Abstract

Objective. To analyze basic medico-statistical indices of the morbidity rates of the malignant tumors of the larynx in the Republic of Belarus.

Materials and methods. Data of the Belarusian Cancer Register on all detected cases of the malignant tumors of the larynx in the Republic of Belarus over 2000-2019 served as the material of the study. The following rates were studied: age standardized morbidity, gross intensive morbidity, morbidity separately in the general population and working age population, in urban and rural population, males and females. All epidemiological indices for the periods 2000-2005 and 2015-2019 in the country and across the regions of the Republic of Belarus were compared.

Results. The age standardized morbidity rate in Belarus increased from 4.2 cases/year per 100,000 population in 2000 to 5.8 in 2019. The gross intensive morbidity rate increased from 5.5 to 7.3, respectively. An increase in the morbidity rate from 4.0 in 2000 to 4.3 in 2019 was noted in the working age population. The gross intensive morbidity rates in males were on average 33.9 times higher than in females, and in the urban population – 1.7 times lower than those in the rural population. The maximal increase in the morbidity rate was registered in the working age population of rural areas – by 60.3% during the monitored period. A statistically significant increase in the morbidity rate was noted in the city of Minsk. The morbidity rates registered in Minsk were statistically significantly lower than those in the republic. In other regions, there was no significant difference in the morbidity rates and growth dynamics from the indices in Belarus as a whole.

Conclusion. Malignant tumors of the larynx are characterized by a slow increase of the morbidity rate for the last 20 years in Belarus. The observed epidemiological trends deter
