New study tracks prostate tumors on MRI after radiation
NCT ID NCT06822491
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study aims to see how prostate tumors change on MRI scans shortly after a precise type of radiation therapy (SBRT). Researchers will compare these MRI changes with PSA levels in the blood. The study involves 28 men with localized prostate cancer and is designed to improve understanding of early treatment response.

Inclusion Criteria: * Patients with histologically confirmed localized prostate cancer who are planned for CT- or MRI-adaptive SBRT for prostate cancer; * Presence of PIRADS ≥3 lesion(s) in a mpMRI correlating with Gleason ≥7 score at diagnosis; * Intermediate to (very) high risk localized prostate cancer (≤ cT3b and cN0); * ECOG performance status of 0-2; * Age ≥ 18 years; * PSMA PET ≤3 months is compulsory for high-risk prostate cancer (as part of clinical routine); * Written informed consent. * Willingness and ability to comply with schedule Exclusion Criteria: * Previous (≤10 years) local therapy of the prostate including transurethral resection of the prostate (TURP), * Contraindication for MRI; * Previous (≤10 years) radiotherapy in the pelvis; * Lymph node metastases or distant metastases (i.e. no localized prostate cancer); * Participation in a clinical trial which might influence the results of this project; * Claustrophobic anxiety; * Uncontrolled intercurrent illness; * Relation to investigator (family or professional)
