Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

In this study, the investigators aim to determine if the Vienna nomogram increases the detection rate of TRUS-guided prostate biopsies by conducting a prospective randomized study comparing the Vienna nomogram with a 10-core biopsy protocol.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Trans rectal ultrasound (TRUS) guided prostate biopsy remains the standard for prostate cancer diagnosis. However, the standard protocols miss 15 to 30% of cancers, leading to a variable number of repeat biopsies.

In 2005 the Vienna nomogram was introduced, defining the number of cores to be obtained in a prostate biopsy in relation to age and prostate volume in patients with a serum PSA level of 2-10 ng/mL.

The objective of the study is to determine if the Vienna nomogram increases the detection rate of trans rectal ultrasound guided prostate biopsies, compared to a 10-core biopsy.

This prospective randomized study enrolled men eligible for a prostate biopsy were randomized to a Vienna nomogram protocol or a 10-core protocol. They were further stratified according to age (≤65; \>65 and ≤70; \>70 years) and prostate volume (≤30; \>30 and ≤50; \>50 and ≤70; \>70 cc).

A subgroup analysis for patients with serum PSA values between 2 and 10 ng/mL was performed.
