Abstract. Numerous literature data confirm that environmental factors play an important role in the etiology of gastric cancer. However, the relationship between long-term exposure to air pollutants and gastric cancer is not unambiguous. Such studies using a geospatial approach have not been previously conducted in the Republic of Tatarstan.
The study objective is conduct a spatial analysis of the incidence of gastric cancer (GC) in the Republic of Tatarstan in 2012–2021 and to reveal its dependence on meteorological parameters and phenomena.
Results. The article presents the results of a study of the incidence of gastric cancer in the municipalities and urban districts of the Republic of Tatarstan in 2012–2021. The territory of the Republic of Tatarstan was divided into zones by incidence levels; the dynamics of average annual incidence rates and its trend were assessed. A relationship was established between morbidity and a set of meteorological variables and phenomena. A forecast of the dynamics of morbidity up to 2030 was made.
Conclusions. The results obtained can be used in planning measures to reduce the incidence of gastric cancer.
Key words: incidence of malignant neoplasms localized in the stomach, zoning, dynamics and trend of incidence, complex of meteorological variables and phenomena.
