Image-guided prostate biopsy using PET/CT for men with prior negative biopsies

Evaluation of 68Ga-PSMA-11 PET Guided Prostate Biopsy in Men With Suspicion of Clinically Significant Prostate Cancer and Prior Negative/Inconclusive Biopsy: A Prospective Exploratory Study

Early Phase 1 Interventional Jonsson Comprehensive Cancer Center · NCT05160597

This study is testing a new way to find prostate cancer in men who have had negative biopsy results by using special imaging to guide the biopsy and see if it helps catch more serious cases.

What this trial studies

This early phase I trial evaluates the effectiveness of an image-guided prostate biopsy using 68Ga-PSMA-11 PET/CT imaging in diagnosing prostate cancer in men who have previously had inconclusive or negative biopsy results. The study aims to improve the detection rate of clinically significant prostate cancer by targeting areas of PSMA uptake within the prostate. Participants will receive an intravenous dose of 68Ga-PSMA-11 followed by a PET/CT scan, and those with positive uptake will undergo a biopsy guided by the imaging results. This approach may help reduce unnecessary treatments for low-risk cases while ensuring high-risk cases are accurately diagnosed.

Who should consider this trial

Good fit: Ideal candidates are men with a suspicion of clinically significant prostate cancer who have had inconclusive or negative prior biopsies and show focal 68Ga-PSMA-11 uptake.

Not a fit: Patients with negative 68Ga-PSMA-11 uptake or those with recurrent prostate cancer will not benefit from this study.

Why it matters

Potential benefit: If successful, this method could significantly improve the accuracy of prostate cancer diagnoses in men with prior inconclusive biopsies.

How similar studies have performed: While this approach is innovative, similar imaging-guided biopsy techniques have shown promise in improving cancer detection rates.
