About this study

Hypofractionated radiosurgery with 5 fractions is considered standard of care for localized prostate cancer. The investigators initiated this multicenter phase II prospective trial to analyse feasibility (toxicity) of hypofractionated radiosurgery with 3 fractions in patients with localised prostate cancer under the hypothesis that the ratio of patients with late GU and GI toxicity ≥ grade 2 after 1 year amounts to 8.4% and 1.3% and is significant lower than 16.4% and 5.7% currently.
