Epidemiological features of laryngeal cancer in the Far Eastern Federal District

Abstract

Aim. A scientific assessment of the main indicators of morbidity and mortality of the population from laryngeal cancer in the Far Eastern Federal District over the past ten years (2009-2019).Materials and methods. In the process of work, indicators of morbidity and mortality, reporting forms of statistical registration of oncological patients and regulatory documents of higher organizations, information on ten-year observations on the dynamics of changes in digital values of the investigated pathology were used.Results. The main data on morbidity and mortality of patients with laryngeal cancer are given in the Far Eastern Federal District, where 2019 new cases of malignant neoplasms were registered in 34152, which is 8.5% more than ten years ago. There were 2171 patients with laryngeal cancer under outpatient observation, i.e. 26.5% per 100.000 population in the region. In the structure of primary morbidity and total mortality among all departments of the respiratory system, laryngeal cancer ranked second after malignant neoplasms of the trachea, bronchi and lung. During the study period, the number of patients with advanced forms of the disease increased with a simultaneous decrease in the number of patients with stages I and II of the oncological process. Over the past ten years, the incidence of disease has increased more significantly in the female population. The percentage of actively identified patients during this time increased by several orders of magnitude, with a simultaneous increase in the index of the accumulation of populations of patients with laryngeal cancer. Morphological confirmation of the diagnosis was lower than the Russian average. The proportion of patients registered for five years or more did not reach the average republican values. Lethality in the first year since the diagnosis was established was characterized by dynamically decreasing digital values, despite the increase in the number of neglected cases, which can be explained by the high level of modern methods of treatment.Conclusion. Against the background of the increasing absolute number of patients with malignancies in the Far Eastern Federal District in 2019, there was a decrease in standardized indicators (world standard) of morbidity and mortality from laryngeal cancer in the male population, with an increase in the number of women who fell ill and died from this pathology.
