Revising Incidence and Mortality of Lung Cancer in Central Europe: An Epidemiology Review From Hungary.

ABSTRACT

Objective: While Hungary is often reported to have the highest incidence and mortality rates of lung cancer, until 2018 no nationwide epidemiology study was conducted to confirm these trends. The objective of this study was to estimate the occurrence of lung cancer in Hungary based on a retrospective review of the National Health Insurance Fund (NHIF) database. Methods: Our retrospective, longitudinal study included patients aged ≥20 years who were diagnosed with lung cancer (ICD-10 C34) between 1 Jan 2011 and 31 Dec 2016. Age-standardized incidence and mortality rates were calculated using both the 1976 and 2013 European Standard Populations (ESP). Results: Between 2011 and 2016, 6,996 - 7,158 new lung cancer cases were recorded in the NHIF database annually, and 6,045 - 6,465 all-cause deaths occurred per year. Age-adjusted incidence rates were 115.7-101.6/100,000 person-years among men (ESP 1976 84.7-72.6), showing a mean annual change of - 2.26% (p = 0.008). Incidence rates among women increased from 48.3 to 50.3/100,000 person-years (ESP 1976 36.9-38.0), corresponding to a mean annual change of 1.23% (p = 0.028). Age-standardized mortality rates varied between 103.8 and 97.2/100,000 person-years (ESP 1976 72.8-69.7) in men and between 38.3 and 42.7/100,000 person-years (ESP 1976 27.8-29.3) in women. Conclusion: Age-standardized incidence and mortality rates of lung cancer in Hungary were found to be high compared to Western-European countries, but lower than those reported by previous publications. The incidence of lung cancer decreased in men, while there was an increase in incidence and mortality among female lung cancer patients.
