Resumen
ETXEBERRIA, J. et al. Prostate cancer incidence and mortality in Navarre (Spain). Anales Sis San Navarra [online]. 2018, vol.41, n.1, pp.9-15. ISSN 1137-6627. https://dx.doi.org/10.23938/assn.0123.
Background
Prostate cancer is one of the most commonly diagnosed malignancies among males worldwide. In this study, overall and age-specific incidence and mortality trends are analyzed in order to present the past and current epidemiological situation of the disease in Navarre (Spain).
Methods
Population-based incidence data from the 1975-2010 period, provided by the Cancer Registry of Navarre and prostate cancer specific mortality data for 1975-2013, provided by the Spanish Statistical Office, were used in the analysis. Age-standardized incidence and mortality rates, change-points and annual percentage changes (APC) were estimated by joinpoint regression analysis. One-dimensional P-spline models were used to estimate projections up to 2016.
Results
Considerable increases of cancer incidence rates in men aged 45-74 years were observed, with APC of +4.5% (p<0.001), +9.5% (p<0.001) and +2.4% (p<0.05) in the 1975-1990, 1990-2000 and 2000-2010 periods, respectively. In the older than 74 age-group, an increase of incidence rates in the 1975-1999 period was registered (APC +3.3%, p<0.001), followed by a significant decrease up to 2010 (APC -4.0%, p<0.01). Mortality rates rose until 1995 (APC +2.2%, p<0.001) whereas a decline occurred afterwards up to 2013 (APC -3.4%, p<0.001).
Conclusion
Even though overall prostate cancer incidence rates seem to have stabilized in 2002-2010 in Navarra, trends were different by age groups: increased in men 45-74 years old and decreased in the 75+ year age-group. A decline in mortality rates was observed in both age groups since about 1995. Changes in the use of prostate specific antigen test for screening in oncoming years could affect future prostate cancer trends.
