Brief Summary
A large proportion of men with prostate cancer are overdiagnosed and overtreated mainly due to PSA testing. Active surveillance (AS) aims to reduce these harms by recommending curative treatment only when and if signs of tumor progression occur. There are however a number of uncertainties in AS, the most important being when to initiate treatment. The investigators are therefore starting a large randomized multicenter trial testing the safety of a standardized active surveillance protocol with specified triggers for repeat biopsies and initiation of curative treatment. The standardized protocol is compared with current practice for active surveillance. The primary aim of the study is to reduce overtreatment and subsequent side effects, without increasing the risk of disease progression or prostate cancer mortality.

Outcome Measures
Primary Outcomes (1)
Progression-free survival
Disease progression is defined as 1) cumulative incidence of PSA relapse after curative treatment or 2) cumulative incidence of androgen deprivation therapy in untreated men still in active surveillance.
Median 10 years follow-up
Secondary Outcomes (6)
Cumulative incidence of pT3
Median 10 years follow-up
Cumulative incidence of metastases
Median 10 years follow-up
Cumulative number of treatments with curative intent (mainly radical prostatectomies or local radiotherapy)
Median 10 years follow-up
Cumulative incidence of switch to watchful waiting
Median 10 years follow-up
Prostate cancer mortality
Median 10 years follow-up
- +1 more secondary outcomes
Study Arms (2)
Current clinical practice for active surveillance
ACTIVE COMPARATORIn this arm, patients are monitored according to current clinical practice for active surveillance at the trial centre. Repeat biopsies (and/or other examinations) and curative treatment are performed according to the urologist's judgement.
Standardized triggers for initiation of treatment with curative intent
EXPERIMENTALIn this arm, patients are monitored according to a standardized active surveillance protocol with specific triggers for treatment. Repeat biopsies and curative treatment are only initiated if/when specific criteria are fulfilled.
Interventions
Active monitoring of prostate cancer and curative treatment if there are signs of tumor progression.
