[Problems of monitoring malignant neoplasms of the central nervous system in the Siberian Federal District and ways to solve them].

Background: Incidence and recording of neuro-oncological tumors comprise an important problem in the world and In Russia including the Siberian federal district.

Objective: To analyze the incidence of malignant tumors of the central nervous system (CNS) (C70-72) in the Siberian federal district and appropriate constituent territories.

Material and methods: Analysis of standardized indicators was based on form No. 7 "Information on malignant neoplasms" for the period 2013-2022, population and male-to-female ratio in the Siberian federal district.

Results: The number of patients with CNS tumors increases in the Siberian federal district while relative rates of CNS cancer incidence are stable (men 5.2±0.2%, women 3.8±0.2%). The peak incidence has shifted from the age of 65-69 years to older category (75-79 years). Mean age of patients increased by 4.6 years (53.8±1.9 years in 2022) for men and 5.5 years (58.3±1.7 years in 2022) for women (p<0.001). We developed the algorithm for therapeutic and diagnostic care in patients with CNS tumors to solve permanent organizational problems in the Tomsk region. A specialized neuro-oncological registry based on territorial cancer registry was used.

Conclusion: Development and implementation of neuro-oncological registry programs for all tumors of the central nervous system will be valuable to assess oncological epidemiological situation. Moreover, we can expect earlier diagnosis and timely specialized treatment of such patients.
