Brief Summary

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

Hypofractionated radiosurgery has been investigated in a few trials and appears to be safe and feasible.

Investigators initiated this multicenter phase II prospective trial to analyse feasibility (toxicity) of hypofractionated radiosurgery with 5 fractions in patients with localised prostate cancer under the hypothesis that the ratio of patients with late toxicity ≥ grade 2 after 3 years amounts 4.1% and is significant lower than 12.3% and 8.7% currently.

Detailed Description

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

Experimental radiosurgery of prostate with 5 fractions each with 7,00 Gy (total application rate of 35,00 Gy).

Planned visits are: Baseline, visits at every radiation day and eight follow ups (4-6 weeks, 3 months, 6 months, 1 year and every year thereafter after last day of radiation).
