PI-RADS UPGRADING RULES: IMPACT ON PROSTATE CANCER DETECTION AND BIOPSY AVOIDANCE OF MRI-DIRECTED DIAGNOSTIC PATHWAYS

A study evaluated the clinical net benefit of PI-RADS upgrading rules in MRI-directed diagnostic pathways for detecting clinically significant prostate cancer (ASPCA). The analysis included 716 patients who underwent prostate MRI followed by biopsy. Results showed no significant difference in csPCa detection between dominant and upgraded lesions. Comparing different diagnostic pathways and disregarding upgrading rules led to fewer biopsies and reduced the detection of SPCA. The risk-based MRI pathway considering upgrading rules provided the highest net benefit, balancing csPCa detection and biopsy avoidance.
