Clinical Trial Summary

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

Description:

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.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Toxicity as scored by PROM (Patient Reported Outcome Measures) at 8 weeks	Acute toxicity score by PROM at eight weeks post radiotherapy. The mean PCSS (Prostate Cancer Symptom Scale) bother score for urinary tract will be measured. The primary outcome measurement will be the difference between mean values in the respective treatment arms measured at 8 weeks after end of radiotherapy	8 weeks
Primary	Toxicity as scored by PROM at 8 weeks	Acute toxicity score by PROM at eight weeks post radiotherapy. The mean PCSS bother score for bowel will be measured. The primary outcome measurement will be the difference between mean values in the respective treatment arms measured at 8 weeks after end of radiotherapy	8 weeks
Secondary	Failure free survival	To evaluate the proportion of patients that are failure free at 12 and 36 months, failure free survival (FFS)	12 months, 36 months
