Measuring Prostate Cancer-Derived Extracellular Vesicles After Treatment

Determination of Baseline Levels for Prostate Cancer-Derived Extracellular Vesicles Following Local Treatment of Prostate Cancer

Observational Mayo Clinic · NCT06326216

This study is testing how levels of prostate cancer-related particles in blood and urine change before and after treatment in men with prostate cancer, while also looking at how these levels relate to PSA levels.

What this trial studies

This observational study aims to assess the levels of prostate cancer-derived extracellular vesicles in blood and urine samples from patients undergoing radical prostatectomy and neoadjuvant treatment. The study will compare these levels pre- and post-treatment and analyze their correlation with prostate-specific antigen (PSA) levels. Participants will be divided into cohorts based on their treatment type, and medical records will be reviewed to gather comprehensive data. Additionally, female control patients will also provide samples for comparison.

Who should consider this trial

Good fit: Ideal candidates include adult males aged 18 and older with high-risk prostate cancer who are undergoing primary prostatectomy.

Not a fit: Patients with metastatic prostate cancer or those unable to provide informed consent may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance the understanding of prostate cancer treatment responses and improve patient monitoring.

How similar studies have performed: Other studies have explored the role of extracellular vesicles in cancer, suggesting potential for success in this approach.
