Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

de Novo metastatic prostate cancer with limited metastatic spread benefits from local radiotherapy to the prostate. Two different fractionation schedules will be tested.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Patients with de Novo metastatic prostate cancer with limited disease spread has been shown to gain benefit from local radiotherapy to the prostate. The internationally accepted fractionation schedule is 3 Gy (Gray) x 19-20 over a course of 4 weeks.

There is continous evidence for even more hypo-fractionated radiotherapy with higher fractionation doses. We will test if the schedule of 6.1Gy x 6 compares to standard of 3 Gy x 19 with regard to patient reported side-effects.
