Non-inferiority Study Comparing Salvage Pelvic Radiotherapy in 25 Fractions (62.5 Gy/25) Versus 20 Fractions (52.5 Gy/20) for Recurrent Prostate Cancer After Surgery.

Study Overview This research compares two types of post-operative salvage radiotherapy (SRT) for men with prostate cancer who have had surgery but show signs of recurrence (detectable PSA). The goal is to see if a shorter treatment schedule is as safe and effective as the standard schedule. Why is this study important? After prostate surgery, cancer can return in up to 70-80% of high-risk patients. Radiotherapy helps control this, but the best way to deliver it-especially the number of sessions and whether to treat the pelvic area-is still being studied. Shorter treatments could mean less time in therapy and better quality of life, if such treatments are proven safe. What is being compared? Standard treatment (Arm A): 25 sessions (about 5 weeks) Prostate bed: 62.5 Gy Pelvis: 45 Gy Shorter treatment (Arm B): 20 sessions (about 4 weeks) Prostate bed: 52.5 Gy Pelvis: 43 Gy Both groups may also receive hormone therapy (ADT) for 6-24 months. Main Goal To check if the shorter treatment causes no more side effects (urinary or bowel problems) than the standard treatment, while keeping cancer control similar. Other Things to be Measured Cancer control (PSA levels, spread of disease) Survival Quality of life (urinary, bowel, sexual health questionnaires) Who can join? Men who: Had prostate surgery Have a detectable PSA (≥0.2 ng/mL) No distant metastasis Are in good general health (ECOG 0-2) How long will the study last? About 12 years total: 2 years to enroll patients 10 years of follow-up

PROCARE - PROstate Cancer Real World Evidence Registry

The aim of this registry study with long-term follow-up is to record the course of therapy and disease in patients with recurrent and metastatic prostate cancer. The following patient groups are planned: * Patients with a recurrence of PSA after surgical removal or radiation of the prostate due to prostate cancer; so-called PSA recurrence (relapse) or biochemical recurrence. * Patients with a PSA recurrence who have received treatment by hormone deprivation therapy (so-called androgen deprivation) and in whom the PSA value has nevertheless risen again without spreading to other organs or parts of the body, so-called non-metastatic castration-resistant prostate cancer. * Patients with proven spread to other organs or parts of the body (= metastases, e.g. in the bone) without hormone deprivation therapy having been initiated, so-called metastatic hormone-sensitive prostate cancer. * Patients with prostate cancer and spread to other organs or parts of the body (= metastases) in whom the tumor disease has progressed despite hormone withdrawal treatment (e.g. as evidenced by an increase in PSA), so-called metastatic castration-refractory prostate cancer. These four groups of patients are enrolled and observed independently of each other at different time periods.

A Prospective, Bicentric Evaluation of Fluciclovine PET-imaging in Patients with Prior Negative or Inconclusive PSMA-ligand PET

The REFINE study is evaluating whether a fluciclovine (18F) PET/CT scan can detect recurrent prostate cancer in patients whose previous PSMA PET/CT was negative or inconclusive.

Diagnostic Performance of [18F]PSMA-1007 in the Context of Biochemical Recurrence of Prostate Cancer

Following numerous retrospective studies and Phase-3-Studies with promising results, \[18F\]PSMA-1007 has been approved by european authorities. Therefore, it is a growing deployment of this diagnostic method anticipated. This study aims to investigate the diagnostic performance and clinical impact in a real-world-evidence in the context of regular clinical care. The evidence generated by this approach is supposed to assist in optimizing the management of prostate cancer patients.

68Ga-PSMA-11 Efficacy in Detecting BCR Prostate Cancer in Chinese Patients

This is a prospective, open-label, single-arm, multicenter bridging study in Chinese patients with prostate cancer. This multicenter study is planned to be conducted in patients with biochemical recurrence (BCR) of elevated PSA after radical prostatectomy or radical radiotherapy. This study investigates how well 68Ga-PSMA-11 PET/CT works in detecting BCR prostate cancer in Chinese patient. 68Ga-PSMA-11, developed by Telix, is a new molecular entity tracer with the trade name Illuccix®, which is approved by FDA for the examination of: 1) patients with suspected metastatic PC who are scheduled for initial treatment; 2) patients with biochemical recurrence of elevated PSA levels after initial radical radiotherapy.
