A total of 205 patients presenting with BF after RP were included in this study. Imaging findings on\n 18<\/jats:sup>\n F\u2010DCFPyL PET\/CT were recorded and correlated with the PSA characteristics at BF and pathological features of the original tumour.\n <\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n \n Of the 205 patients, 120 (58.5%) had evidence of abnormal prostate\u2010specific membrane antigen (PSMA) expression compatible with recurrent prostate cancer. Increasing PSA velocity (\n P<\/jats:italic>\n = 0.01), International Society of Urological Pathology (ISUP) Grade Group (\n P<\/jats:italic>\n = 0.02), lymphovascular invasion (\n P<\/jats:italic>\n = 0.05) and nodal positivity (\n P<\/jats:italic>\n = 0.02) at the time of RP were more likely to demonstrate PSMA positivity. Multivariable logistic regression revealed a higher PSA level prior to PSMA PET\/CT (\n P<\/jats:italic>\n < 0.01), adjuvant radiotherapy (\n P<\/jats:italic>\n = 0.09), Gleason score \u22658 (\n P<\/jats:italic>\n < 0.01) and nodal positivity (\n P<\/jats:italic>\n = 0.05) were all predictive of PSMA positivity.\n <\/jats:p>\n <\/jats:sec>\n \n Conclusion<\/jats:title>\n \n 18<\/jats:sup>\n F\u2010DCFPyL PET\/CT positivity, both generally and site specific, correlates with PSA and RP pathological factors. Our results echo cohorts focussing on post\u2010RP patients, those imaged with\n 68<\/jats:sup>\n Ga\u2010PSMA and those concerning biochemical persistence. Nomograms that include risk factors for \u2018PSMA\u2010positive recurrence\u2019 in the BF population may increase the catchment of patients with disease confined to the prostate bed or pelvis who have a greater probability of prolonged disease\u2010free survival.\n <\/jats:p>\n <\/jats:sec>","DOI":"10.1111\/bju.15724","type":"journal-article","created":{"date-parts":[[2022,6,29]],"date-time":"2022-06-29T23:33:53Z","timestamp":1656545633000},"page":"28-36","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["\n Pathological predictors of\n 18<\/sup>\n F\u2010DCFPyL prostate\u2010specific membrane antigen\n <\/scp>\n \u2010\n positive recurrence after radical prostatectomy<\/scp>"],"prefix":"10.1111","volume":"130","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1649-5100","authenticated-orcid":false,"given":"Elisa","family":"Perry","sequence":"first","affiliation":[{"name":"Pacific Radiology Christchurch Canterbury New Zealand"},{"name":"Department of Medical Imaging St. Vincent's Hospital Melbourne Vic.
