Using PSMA-PET CT to monitor prostate cancer in patients on active surveillance

ESCAPE - Evaluation of Prostate Specific Membrane Antigen Positron Emission Tomography-Computed Tomography in Active Surveillance for Prostate CancEr

Not applicable Interventional Weill Medical College of Cornell University · NCT05948657

This study is testing if PSMA-PET CT scans can help men with low-risk prostate cancer on active surveillance see if they still have significant cancer or not.

What this trial studies

This study evaluates the effectiveness of PSMA-PET CT imaging in identifying the absence of clinically significant prostate cancer in men who are on active surveillance for low and favorable intermediate-risk prostate cancer. It is a prospective, multicenter, nonrandomized single-arm study that aims to enroll 200 participants who meet specific NCCN guidelines. The study will assess the diagnostic accuracy of this imaging technique over time, with participants undergoing yearly PSMA-PET CT scans and prostate biopsies to monitor their condition.

Who should consider this trial

Good fit: Ideal candidates are males aged 18 and older with histologically confirmed low or favorable intermediate-risk prostate cancer who are pursuing active surveillance.

Not a fit: Patients who have previously received treatment for prostate cancer or those with a life expectancy of less than 10 years may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a more accurate method for monitoring prostate cancer, potentially reducing unnecessary treatments for patients.

How similar studies have performed: Other studies have shown promise in using advanced imaging techniques for cancer monitoring, but this specific approach with PSMA-PET CT in active surveillance is relatively novel.
