Brief Summary

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

Single-centre single-armed, non-randomized interventional phase II-study of hypofractionated image-guided radiotherapy "IGRT" with weekly magnetic resonance imagings "MRI" for personalized adaptation of the treatment plan depending on individual MR-anatomy of prostate/organ at risks "OAR" during course of IGRT.

Detailed Description

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

IGRT-schedule: 20 fractions to a total dose of 60 Gy

Personalized adaption of treatment plan dependning on volume-/ and constraint-thresholds and evaluation of biomarkers (multiparametric MRI, blood, tissue, stool, urine).

Treatment at MR-Linac allowed

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Hypofractionated image-guided radiotherapy

Hypofractionated image-guided radiotherapy "IGRT" to a total dose of 60 Gy (20 fractions) is performed.

Weekly MRI are used to estimate volume/deformation changes of OAR and target volume.

Intervention: In case of a significant change of target volume or OARs (threshold based) the radiation treatment plan is adapted on individual MR-anatomy.

Group Type OTHER

Plan adaptation of Radiation Treatment in case of anatomical changes

Intervention Type RADIATION

Image guided radiotherapy is given to 60Gy in 20 fractions. Intervention: Radiation treatment plan adaption in case of volume changes of target volume or not meeting OAR constraints due to volume changes.
