Early Detection and Health Care of Prostate Cancer Patients

Early detection and health care of prostate cancer patients – a transnational comparison of political impact assessment and empirical evaluation of the regional heterogeneity in medical care


The Department of Epidemiology and Biometry is collaborating with the University Clinic for Urology at the Oldenburg Hospital, the Epidemiological Cancer Registry of Lower Saxony (EKN) and the Department of Epidemiology at the University Medical Center Groningen on various projects concerning the care and epidemiology of prostate cancer. Among other things, this involves a transnational comparison of physicians' use of PSA testing between Germany and the Netherlands.

Country-specific health policy decisions on prostate specific antigen (PSA) testing or early detection of prostate cancer (C61 (ICD-10)) can have different effects, such as increasing incidence – as is the case in Germany and the Netherlands. Within countries, there is also variability in the use of the PSA test, which is shaped less by national recommendations than by the individual actions and attitudes of physicians.
