What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Cancer recurrence

    Includes:

    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

    Measured: 3, 6, 12, 24 months after treatments

Secondary outcomes (1)
  1. Quality of life

    according to the QLQ C30 and PR25 questionnaire interview

    Measured: 3, 6, 12, 24months after treatments

Questions about this trial

What is this clinical trial studying?

An observational study of Prostate Cancer and Immune Profile, run by National Taiwan University Hospital at 1 site in Taiwan.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 14 Nov 2012. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Taiwan. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Yeong-Shiau Pu, PhD (886-2-23123456 ext. 65249, yspu@ntu.edu.tw), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Cancer recurrence (time frame: 3, 6, 12, 24 months after treatments). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 14 Nov 2012.
