CANCER OF THE LARYNX IN THE AMUR REGION OF FAR EASTERN FEDERAL DISTRICT

Abstract

The article analyzes the main indicators of morbidity and mortality from cancer of the larynx in the period from 1998 to 2014 on the territory of the Amur region of Far Eastern Federal District. In the studied period of time, the incidence of malignant tumors of the larynx substantially decreased with the growth/loss in men of “rough indicators” by -11.89%, of standardized ones by -7.75%. In women, they were +98.31 and +77.77%, respectively. Mortality in contrast to the incidence throughout the years had a negative growth (loss) in absolute terms, “rude” and standardized indicators. The age and sex features of morbidity with larynx cancer were revealed; they show that the maximum number of cancer cases is in the age group of 50 years old and older. The multistage character of the process based on its prevalence was determined. The early stages (I-II) of laryngeal cancer were registered in 13.7% of patients. The quality of cancer services activity was studied by reliability index of accounting for this category of patients, which is usually lower than in other regions of the country (-0.45). The analysis of dynamics of mortality in the first year after diagnosis shows its reduction in cancer of the larynx by 11.0% over the period of 1998-2014. The number of patients who were registered five or more years ago decreased significantly. The estimation of primary care, which is not yet fully in line with current medicine, in the provision of specialized aid to cancer patients in the region was done.
