What does this research mean for the field?

Combining multiparametric magnetic resonance imaging (mpMRI) with prostate-specific antigen density (PSAd) allows for a more effective risk-stratification strategy in selecting patients for prostate biopsy, reducing unnecessary procedures while maintaining high detection rates of clinically significant prostate cancer.

Retrospective analysis demonstrates effective prostate biopsy strategy in men with suspicion of cancer, suggesting better patient management.

Key Points

This study aims to identify the best biopsy strategy by combining mpMRI PI-RADS scores and PSAd levels to improve prostate cancer detection and minimize unnecessary procedures.
Retrospective analysis of 511 men with clinical suspicion of prostate cancer.
Assessment of mpMRI PI-RADS scores and prostate-specific antigen density before biopsy.
Evaluation of various mpMRI/PSAd thresholds for accuracy in detecting clinically significant prostate cancer.
Decision curve analysis to determine the net benefit and outcomes.
Optimal biopsy strategy includes lesions with PI-RADS 4 or 5 and PI-RADS 3 with PSAd ≥0.15 ng/mL/mL.
Negative predictive value of the strategy was 91%, while the positive predictive value was 43%.
16% of men (80 out of 511) could have avoided unnecessary biopsies.
Overdiagnosis of insignificant prostate cancer reduced by 9% (15 out of 159).
Only 4% (7 out of 194) of clinically significant prostate cancer cases were missed.
