Comparing needle sizes for better prostate cancer detection

AOP2780 - Can Needle Size Improve Cancer Detection Rate of Transperineal MRI Target Prostate Biopsy Without Affecting Side Effects?

Not applicable Interventional University Hospital Padova · NCT06420115

This study tests whether using a bigger needle for prostate biopsies helps find cancer better than using a smaller needle for men who might have prostate cancer.

What this trial studies

This study evaluates whether using a larger caliber (16G) needle for transperineal MRI-targeted prostate biopsies improves the detection rate of prostate cancer compared to a smaller caliber (18G) needle. The research focuses on assessing the diagnostic capabilities of each needle size while monitoring for any differences in side effects or complications. Patients with suspected prostate cancer will undergo biopsies using both needle sizes to determine which is more effective in identifying cancerous lesions.

Who should consider this trial

Good fit: Ideal candidates are men with clinical suspicion of prostate cancer and at least one suspicious lesion identified on MRI.

Not a fit: Patients who are under active surveillance or have a prior diagnosis of prostate cancer will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved prostate cancer detection rates, allowing for earlier and more accurate diagnosis.

How similar studies have performed: Other studies have explored needle sizes in prostate biopsies, but this specific comparison of 16G versus 18G is less common, making it a novel approach.
