Cytoreductive Prostatectomy Versus Cytoreductive Prostate Irradiation as a Local Treatment Option for Metastatic Prostate Cancer: a Multicentric Feasibility Trial


Condition: Prostate Cancer Metastatic

Intervention:

  • Procedure: radical prostatectomy
  • Radiation: Whole pelvis radiotherapy

Purpose: According to the guidelines of the European Association of Urology (EAU), the first-line treatment for newly diagnosed mPC consists of immediate castration with the addition of docetaxel or abiraterone acetate. As seen in other well-known solid tumours - such as ovarian, colon and renal cancer - local treatment (LT) of the primary tumour could lead to a survival benefit compared to standard of care (SOC). Several retrospective studies have suggested a survival benefit of local treatment of the primary tumour with SOC versus SOC only in mPC. These patients also have less local symptoms of their disease, which has a major impact on quality of life (QoL). Several prospective studies have already been set up to compare either surgery or radiotherapy with the SOC. In expectation of their results and because randomization seems challenging, the investigators want to set up a trial to evaluate the feasibility of randomization between both local treatment groups.
