Zusammenfassung
Die PSMA-PET/CT-Bildgebung ist zur Lokalisation des Prostatakarzinoms (PCa) in Deutschland zunehmend verfügbar. Die Vor- und Nachteile in den verschiedenen Krankheitsstadien werden evaluiert. Da die klinische Relevanz des Nachweises einer Oligometastasierung in der Primärdiagnostik bisher nicht ausreichend beurteilt werden kann, sollte die Bildgebung nur in klinischen Studien erfolgen. In der Rezidivdiagnostik nach einer Therapie mit kurativer Intention besitzt die PSMA-PET/CT-Bildgebung wertvolles Potential für die Planung einer möglichen Salvagetherapie. Für die Nutzung der PSMA-PET/CT-Bildgebung im metastasierten kastrationsresistenten PCa gibt es aktuell keine Evidenz.
Abstract
Prostate-specific membrane antigen (PSMA) positron emission tomography–computed tomography (PET-CT) imaging for the localization of prostate cancer is increasingly available in Germany. The advances and limitations in different disease stages are reviewed. As the clinical relevance of oligometastatic disease in primary cancer detected by PSMA PET-CT imaging is not yet completely understood, it should only be used in clinical trials. In recurrent prostate cancer after therapy with curative intent, PSMA PET-CT shows encouraging potential for the planning of salvage therapy. In metastatic castration-resistant prostate cancer evidence for its use is not available.
