Focal salvage brachytherapy for recurrent prostate cancer

Salvage High Dose Rate Brachytherapy for Local Recurrence in Prostate Cancer: A Phase II Trial

Not applicable Interventional Aarhus University Hospital · NCT04231006

This study tests if a targeted radiation treatment can help men with prostate cancer that has come back after previous radiation therapy, using special imaging to guide the treatment.

What this trial studies

This study investigates the effectiveness and safety of focal salvage high dose rate brachytherapy (HDR BT) for patients with locally recurrent prostate cancer following definitive external beam radiotherapy. It aims to determine the feasibility of using multiparametric pelvic MRI and PSMA PET/CT to guide the treatment. The study will assess both the efficacy of the treatment and any associated toxicities in this patient population.

Who should consider this trial

Good fit: Ideal candidates are men aged 18 and older who have experienced a local recurrence of prostate cancer after prior definitive radiotherapy and meet specific clinical criteria.

Not a fit: Patients with distant metastases, significant comorbidities, or contraindications to radiation therapy may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could provide a targeted treatment option for patients with recurrent prostate cancer, potentially improving outcomes and reducing side effects.

How similar studies have performed: Other studies have shown promise with similar focal treatment approaches, suggesting potential for success in this novel application.
