Further study details as provided by National Taiwan University Hospital:

Primary Outcome Measures:
  • Cancer recurrence [ Time Frame: 3, 6, 12, 24 months after treatments ]


    1. Biochemical (PSA) recurrence according to the ASTRO or Phoenix criteria for patients undergoing cryotherapy (Cryo) or radiotherapy (RT)
    2. Prostate biopsy positivity
    3. Radiographic evidence of recurrence (CT/MRI, Bone scan, radiographs, etc.) Time to recurrence defined by the either of the above 3 outcome parameters

Secondary Outcome Measures:
  • Quality of life [ Time Frame: 3, 6, 12, 24months after treatments ]
    according to the QLQ C30 and PR25 questionnaire interview

Estimated Enrollment: 160
Study Start Date: October 2011
