The Danish Cancer Registry holds information on all prostate cancers (PCa) cases, including diagnostic TNM. However, stratification according to contemporary risk classification is not possible because histopathological grading and prostate-specific antigen (PSA) level are not registered. The objective of the study was to report clinical characteristics and primary management of men diagnosed with PCa from a primary referral center in Denmark.

Records on all men diagnosed with PCa at the Department of Urology, Frederiksberg Hospital, 1 January 2007 - 31 December 2013, were reviewed. Clinical characteristics and primary treatment were recorded. The National Comprehensive Cancer Network risk group classification was used.
A total of 1934 men with a median age of 69 years (interquartile range 65-75) were diagnosed with PCa in the study period resulting in an incidence rate (World Standard Population) of 84/100 000. Overall, 18% were classified as low-risk, 34% as intermediate-risk, 23% as high-risk, 8% as very high-risk and 17% had metastatic disease at diagnosis. Among men age <65 years 70% had low- or intermediate-risk disease, while this was the case for 58% of men aged 65-75 and 22% of men aged >75. Metastatic disease was found in 11% of men <65 years, 17% of men 65-75 years and 23% of men >75 years. In total 73% of men with low-risk PCa were managed on watchful waiting or active surveillance. Curatively intended treatment was performed in 56% of men with intermediate-risk and 61% of men with high-risk PCa, while hormonal therapy was used in 90% of men with very high-risk and 98% of men with metastatic PCa.
In a population without systematic PSA testing we found a large proportion of patients presenting with advanced PCa at diagnosis. Elderly patients presented with more advanced disease. Curative treatment was primarily used in younger men with clinically localized PCa.
