Is this trial a fit for you?
✓Likely a good fit
Ideal candidates for this study are men aged 18 and older with untreated, high-risk prostate cancer who are planning to undergo radical prostatectomy.
✕Probably not a fit
Patients with predominant small cell or neuroendocrine prostate cancer or those who have received certain prior treatments may not benefit from this study.

What this trial studies
This clinical trial aims to evaluate the effectiveness of 64Cu-SAR-bisPSMA positron emission tomography (PET) in identifying regional nodal metastases in patients with high-risk prostate cancer. Participants will undergo this imaging technique prior to radical prostatectomy to determine its diagnostic performance. The study focuses on patients who have untreated, histologically confirmed adenocarcinoma of the prostate and meet specific high-risk criteria. The results could provide valuable insights into the staging of prostate cancer and guide treatment decisions.
Why it matters
Potential benefit: If successful, this study could improve the accuracy of prostate cancer staging and enhance treatment planning for patients.
How similar studies have gone: Other studies have shown promise in using PET imaging for cancer detection, but the specific use of 64Cu-SAR-bisPSMA is relatively novel.
