Radiation therapy for recurrent prostate cancer
Official title: A Phase II Trial of PSMA-Directed Para-Aortic Radiation Therapy for Oligorecurrent Prostate Cancer - The OCEAN Trial
Run by University of Miami · NCT06392295 · Data updated 2026-11-12
This study is testing a new way to use radiation therapy for men with recurrent prostate cancer to see if it helps control the cancer better while also keeping their quality of life intact.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates include males aged 18 and older with histologically proven prostate adenocarcinoma and oligorecurrent disease limited to specific lymph node regions.
✕Probably not a fit
Patients with extensive disease outside the pelvic and sub-diaphragmatic para-aortic lymph nodes may not benefit from this study.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
This clinical trial aims to improve the control of prostate cancer by delivering radiation therapy specifically to the para-aortic and pelvic lymph nodes, combined with systemic androgen suppression therapy. The study will also focus on preserving the quality of life for patients after radiation treatment. Additionally, it will utilize imaging results from PSMA PET/CT scans to evaluate and manage disease progression effectively.
Why it matters
Potential benefit: If successful, this approach could enhance treatment outcomes for patients with oligorecurrent prostate cancer.
How similar studies have gone: Other studies have shown promise in using targeted radiation therapy for prostate cancer, suggesting a potential for success in this approach.
