High-dose-rate brachytherapy for recurrent prostate cancer

A Pilot Study of Focal Salvage High-Dose-Rate Brachytherapy for Prostate Gland Only Recurrence

Not applicable Interventional University of Rochester · NCT04645810

This study is testing a new way to treat recurrent prostate cancer by using high-dose-rate brachytherapy to target only the cancer spots seen on special scans.

What this trial studies

This study aims to investigate the effects of high-dose-rate (HDR) brachytherapy specifically targeting recurrent prostate cancer lesions identified through AXUMIN PET scans. The approach focuses on treating only the visible recurrent cancer rather than the entire prostate, which is a more recent advancement in prostate cancer treatment. Participants will undergo HDR brachytherapy after meeting specific eligibility criteria, including prior treatment history and confirmation of disease recurrence. The study seeks to gather data on the efficacy and safety of this targeted treatment method.

Who should consider this trial

Good fit: Ideal candidates include men aged 18 and older with a history of localized prostate cancer who have experienced recurrence within the prostate gland as confirmed by an AXUMIN PET scan.

Not a fit: Patients with evidence of metastatic disease outside the prostate or those unable to undergo MRI may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could provide a more effective and less invasive option for patients with recurrent prostate cancer.

How similar studies have performed: While HDR brachytherapy has been used in prostate cancer treatment, this specific approach targeting only visible recurrences is relatively novel and has not been extensively tested in prior studies.
