  • Article: Trends in the lung cancer incidence and mortality in the Slovak and Czech Republics in the contexts of an international comparison.
    [show abstract] [hide abstract]
    ABSTRACT: Lung cancer represents the most frequent cause of cancer-related deaths in the industrialized countries. The aim of this study was to analyze the lung cancer incidence and mortality and the possible reasons for any differences discovered in two neighboring Central European countries-the Slovak Republic. We used linear regression model when analyzing incidence and mortality; the trends are presented with corresponding 95 % confidence intervals (CI) and p-value with null hypothesis being constant with time. Statistically significant increase of age-standardized incidence (0.707/100,000/year, 95 % CI 0.107-1.307, p = 0,025) and mortality (1.339/100,000/year, 95 % CI 1.050-1.629, p < 0.0001) of the lung cancer was revealed in males in the Slovak Republic (1980-1991). On the contrary, values of both indicators were stabilized in the Czech Republic. Since year 1991-2005 a statistically highly significant decrease of both incidence and mortality values was observed in males, which was greater in the Slovak Republic. Peak of the curve was not reached in women population, while incidence and mortality values have significantly continuous growth in both countries. According to the lung cancer incidence and mortality trends in both countries (in correlation with smoking prevalence) we consider the support of efforts to change the attitude towards smoking predominantly in women and younger generation to be the most accurate action to reduce these trends.

    Article: Trends in prostate cancer incidence and mortality before and after the introduction of PSA testing in the Slovak and Czech Republics.
    [show abstract] [hide abstract]
    ABSTRACT: As two neighboring countries in central Europe with national cancer registries, the Slovak (SR) and Czech Republics (CR) are countries with a medium global rate in the occurrence of prostate cancer. This paper analyzes the incidence of prostate cancer and mortality before and after the introduction of PSA testing in the two Republics and the possible reasons for any differences discovered and compares the results with selected regions and countries of the world. In the Slovak Republic, prostate cancer incidence (age-adjusted to the world standard population) has risen from 14.6/100,000 in 1968 (95% CI, ±1.5772) to 36.2/100,000 in 2005 (95% CI, ±2.0678). The estimated annual increase in the incidence during the period 1968-1991 (before nationwide PSA testing) was 0.421; from 1991 (when nationwide PSA testing began) to up to 2003 it was 0.941. Mortality rates grew from 7.3/100,000 in 1968 to 14.9/100,000 in 2005. In spite of the geographic proximity of the two countries, the increase in incidence occurred faster in the Czech than in the Slovak Republic, from 15.8/100,000 in 1977 (95% CI, ±0.9748) to 59.5/100,000 in 2005 (95% CI, ±1.7187). The estimated annual increase in incidence in the Czech Republic for the period of 1977-1991 was 0.581. From 1991 (when national PSA testing began) until 2003, it was 1.981. In the period before 1991, mortality rose more sharply in the Czech than in the Slovak Republic, whereas after the introduction of PSA testing mortality stabilized more quickly in the Czech than in the Slovak Republic. In the Slovak Republic, a significant reduction in mortality was observed after 2002 and has continued to the present and probably is not affected only by the results connected with the increase in PSA testing. The difference in the incidence and mortality of prostate cancer in the Slovak and the Czech Republics results from a difference in the intensity of PSA testing as well as from the introduction of complex, more effective treatment in advanced clinical stages.
