Monitoring low-risk suspected prostate cancer without biopsy

Conducting Active Surveillance Without Prostate Biopsy for Patients With Low-risk Suspected Prostate Cancer Based on USTC Diagnostic Model and PSA Level: a Multicenter Prospective Study

Observational Anhui Provincial Hospital · NCT05940415

This study tests a new way to monitor men with low-risk suspected prostate cancer without immediate biopsy to see if it can safely reduce unnecessary procedures.

What this trial studies

This observational study evaluates the USTC diagnostic model's effectiveness in guiding biopsy decisions for patients with low-risk suspected prostate cancer. Participants will undergo active surveillance instead of immediate biopsy, with regular serum PSA testing and mpMRI assessments to monitor their condition. The study aims to determine the safety and feasibility of this biopsy-free approach, potentially reducing unnecessary procedures for patients. The USTC model will help assess the risk of developing prostate cancer based on individual patient data.

Who should consider this trial

Good fit: Ideal candidates are men with clinically suspected prostate cancer who have low serum PSA levels and a low probability of cancer according to the USTC diagnostic model.

Not a fit: Patients with a history of prostate biopsy or those at higher risk of prostate cancer will not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly reduce the number of unnecessary prostate biopsies for patients with low-risk suspected prostate cancer.

How similar studies have performed: While similar approaches to active surveillance have been explored, this specific method using the USTC diagnostic model is relatively novel.
