Lung cancer incidence trends in Świętokrzyskie Voivodeship in 1999–2013

Introduction : Lung cancer is the most common malignant cancer worldwide. In 2013 a total of 21,524 new cases of lung cancer in Poland and 751 (576 in men and 175 in women, respectively) in Świętokrzyskie Voivodeship were reported. Aim of the research: To assess the dynamics of changes in lung cancer incidence between 1999 and 2013 in the population of inhabitants of Świętokrzyskie Voivodeship by sex. Material and methods : Eleven thousand four hundred and eighteen new lung cancer cases in Świętokrzyskie Voivodeship in 1999–2013 were analysed. Crude rates (CRs) and age-standardised rates (ASRs) per 105 population were calculated, in general and by sex. The analysis of incidence trends was carried out using joinpoint models. Results : In 2013 a significant decrease by 22.3% in lung cancer incidence was reported in comparison with the year 1999. A significant decrease by 32.3% among men and non-significant increase by 32.3% in lung cancer incidence among women were reported. The relative risk of lung cancer incidence in men decreased by 44.5% compared to women. The trend in ASRs showed a significant decrease by 2.0% per year. In the male population a significant decreasing trend by 2.9% per year and a significant increasing trend by 2.1% per year among the female population were observed. The lung cancer incidence among men in Świętokrzyskie Voivodeship decreased, with a simultaneous increase in incidence among women in 1999–2013. Sex was the main factor that differentiated the shaping of incidence trends. A significant decreasing incidence trend among men and a significant increasing incidence trend among women were observed. Conclusions : It is necessary to intensify the primary and secondary prevention of lung cancer in the voivodeship.
