EPIDEMIOLOGICAL ASPECTS OF MALIGNANT SKIN NEOPLASMS MORBIDITY IN SVERDLOVSK REGION

Abstract

Sverdlovsk Region is one of the ten largest industrial regions, which accounts for 50.0 % of the total industrial production of the Russian Federation. The aim of the study is a comparative assessment of malignant skin neoplasms (MNS) incidence in the administrative districts of a large industrial region - the Sverdlovsk Region. Methods. We analyzed the data of state statistical reporting, approved by the Order of Rosstat dated December 29, 2011 No. 520 (as amended on December 30, 2015), annual forms of reporting documentation - form No. 7, form No. 35 for the period from 2003 to 2017 in the Sverdlovsk Region. The morbidity and mortality rates standardized by the world age standard were calculated, gender indicators, the morbidity structure in urban districts were estimated. Results. There was an increase in the incidence of MNS - both skin melanoma (SM) and skin cancer (SC) (an intensive increase by 49.1 and 69.8 %, respectively). The overall increase of SM and SC was higher among women: the increase of SM was 23.1 %, in men - 13.6; SC - women 52.7 %, men 40.5. Number of patients with SM of working age has increased by 41.7 % since 2003. Mortality from MNS has a tendency to decrease; however, the rates of first-year mortality are at a high level. Conclusion. There is an increase in the incidence of MNS in Sverdlovsk region - both SM and SC. However, the incidence rates of SC do not exceed the average Russian levels, in contrast to SM for the past 15 years. The highest incidence of MNS cases is registered on territories with functioning industrial enterprises (Gornozavodskoy and Yuzhniy Administrative Districts, Yekaterinburg) which require further study and preventive measures.
