Brief Summary

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

HYPO-RT-PC boost is is an open-label, multicentre, phase II trial evaluating safety and efficacy of real-time image-guided tumor-directed ultra-hypofractionated radiation boost and lymph node irradiation for patients with node-negative high risk localized prostate cancer.

Detailed Description

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

HYPO-RT-PC boost is is an open-label, multicentre, phase II trial evaluating safety and efficacy of real-time image-guided tumor-directed ultra-hypofractionated radiation boost and lymph node irradiation for patients with node-negative high risk localized prostate cancer. 76 participants will be enrolled in the study.

Specific aims of the study are:

* To study the feasibility of ultra-hypofractionation target lesion boost for node-negative very high-risk prostate cancer together with lymph node irradiation (primary outcome).
* To study the effectiveness of ultra-hypofractionated target lesion boost for high-risk prostate cancer.
* To study the feasibility of defining focal boost during concomitant androgen deprivation therapy with advanced functional imaging methods.
