PI-RR: A Reporting System for Local Prostate Cancer Recurrence Evaluation After Radiation Therapy or Radical Prostatectomy.

ABSTRACT: Biochemical recurrence, marked by rising prostate specific antigen levels, is a common and challenging clinical scenario following curative treatments for localized prostate cancer (PCa), such as radical prostatectomy (RP) or radiation therapy (RT). An accurate assessment is critical for detecting local recurrence and distinguishing it from distant metastatic disease, thereby guiding salvage therapies. While multiparametric MRI has demonstrated strong performance in detecting local recurrence, the lack of standardized reporting has historically limited its clinical utility and reproducibility. To address this variability, an international consensus-based Prostate Imaging for Recurrence Reporting (PI-RR) system was introduced in 2021. PI-RR adopts a 5-point Likert scale, similar to Prostate
