[County differences in incidence and mortality of malignant neoplasms in Hungary between 2005 and 2019].

The objective of our study was to map county differences in incidence and mortality by cancers and examine their changes over time. Based on the database of National Cancer Registry and Central Statistical Office, age-standardized incidence and mortality rates per 100,000 person-years were calculated for each county for 15 cancer types and 3 time periods. East-West divide was apparent in incidence and mortality of lung cancer, with larger weight in East (Borsod-Abaúj-Zemplén, Heves, Jász-Nagykun-Szolnok, Békés counties). Concentration of lip and oral cavity malignancies was identified in the northeastern periphery (Borsod-Abaúj-Zemplén, Szabolcs-Szatmár-Bereg counties). Breast cancer incidence was the highest in Budapest. As a conclusion, changes in cancer incidence and mortality over time were similar to developed countries; however, values were higher. Differences in spatial distribution follow territorial pattern of social deprivation, which correspond to higher prevalence of health risk factors. Our study contributes to planning of public health programs by pinpointing regional inequalities in different cancer types.
