Spanish Urological Association Registry of Patients on Active Surveillance

This study is building a national registry in Spain to track men who choose active surveillance for low-risk prostate cancer — meaning they are being carefully monitored with regular tests rather than immediately treated — to understand the long-term outcomes of this approach. **You may be eligible if...** - Your PSA blood marker is 10 or below (or meets special criteria if your prostate is enlarged) - Your prostate cancer is low-grade (Gleason 6) confirmed by biopsy and specialist review - No more than 2 biopsy samples contain cancer, and the amount of cancer in each sample is limited - Your cancer appears confined to the prostate at an early stage - You are under 80 years old with a life expectancy of more than 10 years - You understand what active surveillance means and have signed a consent form **You may NOT be eligible if...** - You are unwilling to undergo repeat biopsies as part of monitoring - You refuse to sign the informed consent form - Your treating hospital cannot perform a confirmatory biopsy at 6 months Talk to your doctor to see if this trial is right for you.
