Introduction. Malignant brain and other central nervous system tumors show a statistically significant increased incidence worldwide (GLOBOCAN, 2018).The study objective – to estimate the incidence of malignant brain and other central nervous system tumors in Siberia and the Russian Far East.Materials and methods. Using data from the population-based cancer registry in Siberia and the Russian Far East, we calculated the cancer incidence rates, the age-standardized incidence rates (ASIR), the index accuracy (the ratio of the number of cancer-related deaths to the number of new cases) of malignant brain and other central nervous system tumors during the period 2010 to 2019.Results. During the period 2010 to 2019, brain and other central nervous system malignances in males were the 14th most common cancers in Siberian and the Russian Far Eastern region, with the incidence of 1.6 % in 2010 and 1.5 % in 2019. In females, brain and other central nervous system malignances were the 16th most common cancers, with the equal incidence of 1.3 % in 2010 and 2020. Overall, the incidence rate of malignant brain and other central nervous system tumors in Siberian and the Russian Far Eastern regions increased from 5.1 to 5.6 per 100 000 with rate of increase of 9.8 %, including the territories of the Republic of Kamchatka (238.5 %), Amur (147.8 %), Khakassia (89.1 %), Irkutsk (65,1 %), Krasnoyarsk (37.8 %), and Primorsky (33.3 %) regions. The incidence rate decreased in the Kemerovo region (34.4 %) and the Trans-Baikal Territory (44.4 %). In women of Siberian and the Russian Far Eastern regions, the incidence rate was slightly increased from 3.7 to 4.0 per 100 000, the overall rate of increase being 8.1 %. The highest incidence rate was registered in the Altai Territory (47.8 %), Novosibirsk region (33.3 %), the Republic of Khakassia (25.0 %), Amur region (246.2 %), but the lowest incidence rate was observed in the Kemerovo region (7.0 %) and the Trans-Baikal Territory (61.1 %).The index accuracy indicated problems with the ...
