Een vergelijking van wereldwijd toegepaste prognostische risicoclassificatiesystemen en de prevalentie van metastasen op PSMA PET/CT bij patiënten met nieuw gediagnosticeerde prostaatkanker
摘要
Various risk classification systems (RCSs) are used globally to stratify newly diagnosed patients with prostate cancer (PCa) into prognostic groups. This study evaluated the predictive value of risk groups (low-, intermediate-, and high-risk) within four RCSs (EAU, NCCN, CPG, and CAPRA) for detecting metastases on primary PSMA-PET/CT. Metastases were observed in 35% (931/2.630) of patients. Prevalence among intermediate- and high-risk groups ranged from 12 to 46%. Two RCSs subdivided these groups: metastatic disease was found in 5.8%, 13%, 22%, and 62% for favorable intermediate-, unfavorable intermediate-, high-, and very-high-risk PCa (NCCN); and 6.9%, 13%, 21%, and 60% for the corresponding CPG groups. This study highlights the importance of detailed risk stratification, and PSMA-PET/CT for primary staging should be reserved for patients with unfavorable intermediate-risk prostate cancer or higher.
