Study Details

Study Description

Brief Summary

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.

Arms and Interventions

Arm Intervention/Treatment
Experimental: Radical prostatectomy

Procedure: radical prostatectomy
can be performed either open, laparoscopic or robot-assisted, which is chosen by the discretion and expertise of the performing surgeon

Experimental: Radiotherapy

Radiation: Whole pelvis radiotherapy
radiation of prostate bed and pelvis

Outcome Measures

Primary Outcome Measures

  1. Feasibility of randomization between both treatment arms as assessed by the randomized proportion [48 months]

    In this trial we want to assess whether it is feasible to randomize patients into both treatment arms. All patients eligible for inclusion will be reported. The eventual proportion of randomized patients will be evaluated. Reasons for exclusion will be monitored.

Secondary Outcome Measures

  1. castration-resistant free survival [48 months]

    Calculated starting from date of randomization until castration-resistant disease development, as defined by the European Association of Urology (EAU) guidelines
