However, because of the narrow availability of (68)Ga the development of alternative tracers is of high interest. The objective of this study was to examine the value of the new PET tracer (18)F-PSMA-1007 for the staging of local disease by comparing it with multiparametric MRI (mpMRI) and radical prostatectomy (RP) histopathology. Methods: In 2016, (18)F-PSMA-1007 PET/CT was performed in 10 men with biopsy-confirmed high-risk PCa. Nine patients underwent mpMRI in the process of primary diagnosis. Consecutively, RP was performed in all 10 men. Agreement analysis was performed retrospectively. PSMA staining was added for representative sections in RP specimen slices. Localization and agreement analysis of (18)F-PSMA-1007 PET/CT, mpMRI, and RP specimens was performed by dividing the prostate into 38 sections as described in the prostate imaging reporting and data system (PI-RADS) (version 2). Sensitivity, specificity, positive predictive values, negative predictive values (NPVs), and accuracy were calculated for total and near-total agreement. Results:(18)F-PSMA-1007 PET/CT had an NPV of $68\%$ and an accuracy of $75\%,$ and mpMRI had an NPV of $88\%$ and an accuracy of $73\%$ for total agreement. Near-total agreement analysis resulted in an NPV of $91\%$ and an accuracy of $93\%$ for (18)F-PSMA-1007 PET/CT and $91\%$ and $87\%$ for mpMRI, respectively. Retrospective combination of mpMRI and PET/CT had an accuracy of $81\%$ for total and $93\%$ for near-total agreement. Conclusion: Comparison with RP histopathology demonstrates that (18)F-PSMA-1007 PET/CT is promising for accurate local staging of PCa.}, cin = {C060 / E010 / E030 / E060 / L101}, ddc = {610}, cid = {I:(DE-He78)C060-20160331 / I:(DE-He78)E010-20160331 / I:(DE-He78)E030-20160331 / I:(DE-He78)E060-20160331 / I:(DE-He78)L101-20160331}, pnm = {315 - Imaging and radiooncology (POF3-315)}, pid = {G:(DE-HGF)POF3-315}, typ = {PUB:(DE-HGF)16}, pubmed = {pmid:28473595}, doi = {10.2967/jnumed.116.189233}, url = {https://inrepo02.dkfz.de/record/130830}, }
