About this trial
A prospective, single-arm phase II study is the individualization of RT for patients with high-risk localized PCa based on multimodal artificial intelligence (MMAI). All patients will receive the current standard of care: (i) a dose escalation to the prostate via HDR brachytherapy, (ii) two years of ADT and (iii) whole-pelvis UHF-RT (5 fractions).
Eligibility criteria
This trial does not accept healthy volunteersQualifiers
Histologically confirmed adenocarcinoma of the prostate (histological confirmation can be based on tissue taken at any time, but a re-biopsy should be considered if the biopsy is more than 12 months old)
Primary PCa (in PSMA-PET imaging and multiparametric magnetic resonance imaging (mpMRI)
High- or very high-risk according to NCCNv1.2023 criteria
Signed written informed consent for this study
Disqualifiers
Prior radiotherapy to the prostate or pelvis
Prior radical prostatectomy
Prior focal therapy approaches to the prostate
Evidence of pelvic nodal disease (cN+) in mpMRI and/or PSMA-PET/CT
Trial design
Single group
Treatments tested in this trial
Androgen Deprivation Therapy (ADT) - Goserelin
DrugThe patients under ADT and the patients who will receive the ADT during the study will be included in the trial. * ADT will be applied for 24 months in total * ADT must be given concurrently and adjuvant
High-Dose-Rate Interstitial Brachytherapy (HDR BRT)
RadiationHDR BRT Procedure will be performed using transperineal catheter implantation under transrectal US-guidance performed under anesthesia, spinal or general with patient in high lithotomy position.)
radiotherapy
RadiationEBRT prostate + elective pelvis (Ultra-hypofractionated): 25 Gy in 5 Gy per fraction
Treatment groups
Trial outcomes
Primary outcomes
cumulative GU toxicity
Primary endpoint is cumulative GU toxicity according to RTOG grading after minimum FU time of two years.
Secondary outcomes
Time to local or regional failure
Time to local or regional failure; after end of RT. Local or regional recurrences have to be confirmed by PSMA-PET or mpMR imaging. For the diagnosis of local failure a verification via biopsy is warranted.
MMAI classifier
Prognostic influence of MMAI classifier for outcome; the ArteraAI Prostate Test score (ranging from 0.0 to 1.0)
Testosterone
Testosterone recovery is to be done through blood test
Metastatic free survival (MFS)
MFS after end of RT, (all metastases have to be confirmed by PSMA-PET/CT or mpMR imaging)
