Purpose: Treatment of primary prostate cancer extremely depends on preoperative stage. The role of 18F-1007-PSMA-PET/CT in preoperative staging has not been well defined. Our aim was to compare the diagnostic performance of 18F-1007-PEMA-PET/CT, mpMRI, and mpMRI + PEMA-PET/CT in local progression and lymph node invasion of prostate cancer using histopathology as the gold standard. Materials and methods: In this retrospective study, all patients with prostate cancer who underwent mpMRI and 18F-PSMA-1007-PET/CT before operation were included. The role of preoperative imaging was evaluated by predicting the sensitivity and specificity of EPE (extraprostatic extension), SVI (seminal vesicle invasion), and lymph node invasion results. Results: Ultimately, 130 patients were included in this study. In the preoperative judgment of EPE and SVI, mpMRI + PSMA-PET/CT had higher sensitivity and specificity. When predicting lymph node metastasis, PSMA-PET/CT was the best choice. The accuracy of mpMRI + PSMA-PET/CT and PSMA-PET/CT in the T and N stages, respectively, was affected by the least factors. Conclusions: Based on the combined results of mpMRI and 18F-1007-PSMA-PET/CT, the accuracy of the preoperative judgment of prostatic capsule invasion can be improved, which may be conducive to developing intra-fascial technology while ensuring no tumor-touch isolation. PSMA-PET/CT has the advantages over mpMRI alone in terms of lymph node positivity. Compared with PSMA-PET/CT alone, the combined results can improve the sensitivity, but reduce specificity. Therefore, it is recommended to focus on PSMA-PET/CT to decide whether lymph node dissection should be performed. [ABSTRACT FROM AUTHOR] |
