Prostate Imaging for Recurrence Reporting System Made Easy: A Case-Based Review of Prostate Cancer Local Recurrence...

Prostate cancer (PCa) is one of the most prevalent cancers worldwide. Even following appropriate initial treatments, a subset of the patients develops tumor recurrence. Magnetic resonance imaging (MRI) is pivotal in investigating local recurrence, but its performance is limited in detecting recurrence at other sites (especially in subcentimeter lymph nodes). Recently, an expert consensus proposed a scoring system for MRI-based assessment of local recurrence, called prostate imaging for recurrence reporting system (PI-RR). This case-based review describes the expected post-treatment changes and MRI findings of local PCa recurrence after RP and RT.
