Study Details

Study Description

Brief Summary

A phase IIR cmRCT trial companion to PERa registry, investigating the merit of SABR consolidation in men with metastatic prostate cancer. 80 patients will be randomly selected to be offered experimental SABR based on PSMA-PET detected disease after maximal systemic response. The primary endpoint is the rate of FFS at 1 year. Patients will be stratified according to hormone sensitive vs resistant disease prior to randomisation.

Condition or Disease Intervention/Treatment Phase
  • Radiation: SABR
  • Other: no RT

Outcome Measures

Primary Outcome Measures

  1. FFS [1 year]

    FFS is defined as time from randomization to the first of the following events: PSA progression, radiographic or clinical progression.

Secondary Outcome Measures

  1. HRQoL [5 years]

  2. Toxicity [5 years]

    CTCAEv5, incidence rate

  3. Time to progression [5 years]

Inclusion Criteria:

3.1.1 Enrolled in PERa (CHUM CER 17.032) and randomly selected for AnChoR-Prostate.
