Condition prostate cancer
Treatments surveillance, salvage treatment
Phase phase 2
Sponsor University Hospital, Ghent
Start date May 2012
End date May 2017
Trial size 54 participants
Trial identifier NCT01558427, 2012/156


Prostate cancer patients diagnosed with a biochemical recurrence and limited metastases are conventionally treated with androgen deprivation therapy. However, in patients with limited metastatic load, the time to progression might be. Subsequently, active surveillance of these patients until progression might defer the start of androgen deprivation therapy (ADT) for several months to years. As an alternative, salvage treatment of the limited number of metastases with either surgery or radiotherapy might postpone the start of ADT even longer. The current trial hypothesizes that ADT might be deferred longer following salvage treatment as compared to active surveillance.

Study Design

Allocation randomized
Endpoint classification efficacy study
Intervention model parallel assignment
Masking open label
Primary purpose treatment
Active monitoring of patients with low volume metastases with Prostate Specific Antigen (PSA) and sequential imaging.
Active clinical surveillance
Surgical or radiotherapy treatment of metastases.
salvage treatment
Surgical removal of metastases, or stereotactic body radiotherapy of metastases.
