Background and Objectives: Prostate cancer (PCa) is a common disease with a significant amount of patients first diagnose with locoregional or distant metastases. This is why it is essential to have imaging tests with sufficient sensitivity and specificity. Having traditional imaging methods with recognized limitations, PET-PSMA is born as a weapon to revolutionize the management of PCa. Material and Methods: We made a comprehensive literature review from August to October 2023 using databases and also a review of key clinical guidelines with the topic, focusing on sensitivity and specificity on PSMA-PET, its use in detecting lymph node metastases (LNm), integration into nomograms, comparison with conventional imaging and current guideline recommendations. Results: After considering search strategy, inclusion and exclusion criteria; 4 articles and 5 guidelines were particularly taken into account in this review. Most of them conclude with high specificity and limited sensitivity for 68Ga-PSMA-PET, increasing detection rates with respect to conventional imaging modalities, specially in high-risk PCa patients; but it cannot replace an extended pelvic lymph node dissection (ePLND) at this time. Conclusions: Although PSMA-PET enhanced sensitivity and specificity over conventional imaging modalities offer a more precise evaluation of disease extent; currently, prospective studies demonstrating a survival benefit are lacking, so caution is advised when making therapeutic decisions.
