Frequency of Biopsy and Tumor Grade Before vs After Introduction of Prostate Magnetic Resonance Imaging.

ABSTRACT:

Importance

In randomized clinical trials (RCTs), magnetic resonance imaging (MRI) before prostate biopsy has been associated with fewer biopsies, decreased detection of Gleason score 6 cancers, and increased detection of Gleason score 7 or higher cancers.

Objective

To study whether MRI of the prostate before the decision to biopsy is associated with biopsy frequency and distribution of Gleason score in clinical practice.

Design, setting, and participants

This is a retrospective, population-based cohort study of men in Jönköping Region, Sweden. Men with prostate-specific antigen (PSA) level measured between November 2011 and 2020 were monitored until January 31, 2021. Men with known prostate cancer were excluded. Data analysis was performed from July to December 2022.<
