However, since the integration of 18F-PSMA-1007-PET/CT into the clinic, a relapsed tumor can now easily be detected by hybrid imaging. The present study aimed to evaluate and map the allocate relapse in a large cohort of prostate cancer patients focusing on individual patient management conclusions for radiation therapy.The current study included 135 men with prostate cancer after primary treatment who underwent 18F-PSMA-1007-PET/CT due to biochemical relapse detecting a local relapse. Imaging data were reassessed and analyzed with regard to relapse locations. For the correlation of tumor foci with clinical data, we used binary logistic regression models as well as the Kruskal-Wallis test and Mann-Whitney test.In total, 69.6% of all patients (mean age: 65 years) underwent prostatectomy while 30.4% underwent radiation therapy. PET imaging detected most frequently a unifocal relapse (72.6%). There was a statistically significantly higher rate of ipsilateral cases among the relapsed tumors. Comparing both treatment approaches, tumors relapsed most commonly within the posterior region after surgery and transition/peripheral zone after radiation therapy, respectively.The present study confirms that 18F-PSMA-1007-PET/CT is highly suitable for the localization and allocation of a local relapse in patients with prostate cancer. The data enable further optimizing dose prescriptions and target volume delineations of radiation therapy in the future. 000181428 536__ $$0G:(DE-HGF)POF4-315$$a315 - Bildgebung und Radioonkologie (POF4-315)$$cPOF4-315$$fPOF IV$$x0 000181428 588__ $$aDataset connected to CrossRef, PubMed, , Journals: inrepo02.dkfz.de 000181428 650_7 $$2Other$$a18F-PSMA-1007 000181428 650_7 $$2Other$$aLocal relapse 000181428 650_7 $$2Other$$aPET/CT 000181428 650_7 $$2Other$$aPSMA 000181428 650_7 $$2Other$$aProstate cancer 000181428 7001_ $$aKroener, R.
