Background: In recent years nuclear medicine theranostics using radiolabeled prostate-specific membrane antigen (PSMA) ligands have gained increasing importance in the management of prostate cancer. Aim: The aim of this work is to highlight the value of theranostic concepts using radiolabeled PSMA ligands for both the diagnostic work-up and treatment of advanced prostate cancer. Material and methods: The currently available knowledge in the literature is summarized and presented. Results: The use of PSMA in positron emission tomography-computed tomography (PET/CT) shows a high sensitivity and specificity for prostate cancer imaging, particularly in patients with biochemical recurrences. Furthermore, promising results are also reported for staging of primary prostate cancer and treatment monitoring. In addition, radioligand therapy using alpha and beta emitters is a promising third line treatment option in intensively pretreated patients with metastases. The reduction of side effects and optimization of the treatment sequence of radioligand therapy is of increasing importance. Conclusion Nuclear medicine theranostics have an increasing clinical impact on the diagnostics and treatment of prostate cancer.
