OBJECTIVE

To study the epidemiological features of malignant neoplasms of the oral cavity in men and women of the Siberian Federal District (SFD) in 2013—2022.

MATERIALS AND METHODS

The calculation of epidemiological data based on forms № 7 for 2013—2022 of territorial entities of the Siberian Federal District. Calculations and processing of the material were carried out using the programs Oncostat, Cancer Care Indicators, JASP 0.18.3.0 and Excel 2016.

RESULTS

Oral cancer in young adults in the Siberian Federal District was the 10-th most common cancer in males (4.1%) and 14-th most common cancer in females. Despite the fact that oral cancer incidence among young adults showed a tendency to increase, a statistically significant increase was observed only in the Irkutsk Region. Age-specific incidence rates significantly increased in females aged 40—44 years, (p≤0.05). Stagnation of the most diagnostic quality parameters was observed. The early cancer detection rate (stage I—II) was 34.1%, advanced stage cancer detection rate (stages III—IV) was 65.2%, and one-year mortality rate was 31.1%. In terms of the early diagnosis, positive changes were observed only in the Krasnoyarsk Territory. There was a trend towards an increase in the percentage of actively detected cancer cases and proportion of patients who were registered for 5 years and more, which indicates patient optimization registration and treatment quality.

CONCLUSION

The upward trend in the of oral cancer incidence in the young population cohort, especially in females, and the lack of positive changes in the quality of oral cavity cancer early detection leads to the relevance of studying the epidemiological aspects and assessing oral cancer risk factors with further recommendations for optimizing early diagnosis.
