Brief Summary

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

The study offers focal salvage brachytherapy for prostate cancer patients with a local recurrence after primary defintive radiotherapy

Detailed Description

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

The aim of this study is to examine the efficacy and toxicity of focal salvage high dose rate brachytherapy (HDR BT) for patients with locally recurrent prostate cancer after definitive external beam radiotherapy. Furthermore, the investigators want to assess, whether it is feasible to perform salvage HDR BT as a focal treatment based on multiparametric (mp) pelvine MRI and PSMA PET/CT.
