Primary Outcome Measures:
  • Prostate cancer-specific survival [ Time Frame: minimal observation time of 13 years for last study patient ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • - Overall survival [ Time Frame: minimal observation time of 13 years for last study patient ] [ Designated as safety issue: No ]

Procedure/Surgery: Active Surveillance
Procedure: Active Surveillance

Detailed Description:

The study will compare four possible therapy options for treatment of newly diagnosed prostate cancer with low or "early intermediate" risk according to the patients preferences.

The Following hypotheses will be tested:

  • Radiation is not relevantly worse compared to prostatectomy with regard to time to prostate cancer-related deaths
  • Permanent seed implantation therapy not inferior to prostatectomy with regard to time to prostate cancer-related deaths.
  • Active Surveillance does not lead to a significant decrease of time to prostate cancer-related deaths compared to prostatectomy.

That for patients with newly diagnosed prostate cancer will be randomized into one of the four treatment arms. Randomization may be limited to at least two of the four treatment arms if a patient refuses one or two of the four treatment arms according to his own preference.
