We validated a RM combining mpMRI and clinical parameters for the probability of harboring significant prostate cancer (sPC, Gleason Score ≥ 3+4) for biopsy-naïve men.The original RM was based on data of 670 biopsy-naïve men from Heidelberg University Hospital who underwent mpMRI with PI-RADS scoring prior to MRI/TRUS-fusion biopsy 2012-2015. Validity was tested by a consecutive cohort of biopsy-naïve men from Heidelberg (n = 160) and externally by a cohort of 133 men from University College London Hospital (UCLH). Assessment of validity was performed at fusion-biopsy by calibration plots, receiver operating characteristics curve and decision curve analyses. The RM`s performance was compared to ERSPC-RC3, ERSPC-RC3+PI-RADSv1.0 and PI-RADSv1.0 alone.SPC was detected in 76 men (48%) at Heidelberg and 38 men (29%) at UCLH. The areas under the curve (AUC) were 0.86 for the RM in both cohorts. For ERSPC-RC3+PI-RADSv1.0 the AUC was 0.84 in Heidelberg and 0.82 at UCLH, for ERSPC-RC3 0.76 at Heidelberg and 0.77 at UCLH and for PI-RADSv1.0 0.79 in Heidelberg and 0.82 at UCLH. Calibration curves suggest that prevalence of sPC needs to be adjusted to local circumstances, as the RM overestimated the risk of harboring sPC in the UCLH cohort. After prevalence-adjustment with respect to the prevalence underlying ERSPC-RC3 to ensure a generalizable comparison, not only between the Heidelberg and die UCLH subgroup, the RM`s Net benefit was superior over the ERSPC`s and the mpMRI`s for threshold probabilities above 0.1 in both cohorts.The RM discriminated well between men with and without sPC at initial MRI-targeted biopsy but overestimated the sPC-risk at UCLH. Taking prevalence into account, the model demonstrated benefit compared with clinical risk calculators and PI-RADSv1.0 in making the decision to biopsy men at suspicion of PC. However, prevalence differences must be taken into account when using or validating the presented risk model. 000144615 536__ $$0G:(DE-HGF)POF3-315$$a315 - Imaging and radiooncology (POF3-315)$$cPOF3-315$$fPOF III$$x0 000144615 588__ $$aDataset connected to CrossRef, PubMed, 000144615 7001_ $$aGiganti, Francesco$$b1 000144615 7001_ $$0P:(DE-He78)1042737c83ba70ec508bdd99f0096864$$aWiesenfarth, Manuel$$b2$$udkfz 000144615 7001_ $$aStabile, Armando$$b3 000144615 7001_ $$aMarenco, Jose$$b4 000144615 7001_ $$aOrczyk, Clement$$b5 000144615 7001_ $$aKasivisvanathan, Veeru$$b6 000144615 7001_ $$aNyarangi-Dix, Joanne Nyaboe$$b7 000144615 7001_ $$aSchütz, Viktoria$$b8 000144615 7001_ $$0P:(DE-HGF)0$$aDieffenbacher, Svenja$$b9 000144615 7001_ $$aGörtz, Magdalena$$b10 000144615 7001_ $$aStenzinger, Albrecht$$b11 000144615 7001_ $$aRoth, Wilfried$$b12 000144615 7001_ $$aFreeman, Alex$$b13 000144615 7001_ $$aPunwani, Shonit$$b14 000144615 7001_ $$0P:(DE-He78)ea098e4d78abeb63afaf8c25ec6d6d93$$aBonekamp, David$$b15$$udkfz 000144615 7001_ $$0P:(DE-He78)3d04c8fee58c9ab71f62ff80d06b6fec$$aSchlemmer, Heinz-Peter$$b16$$udkfz 000144615 7001_ $$aHohenfellner, Markus$$b17 000144615 7001_ $$aEmberton, Mark$$b18 000144615 7001_ $$aMoore, Caroline M$$b19 000144615 773__ $$0PERI:(DE-600)2267670-3$$a10.1371/journal.pone.0221350$$gVol. 14, no. 8, p. e0221350 -$$n8$$pe0221350 -$$tPLOS ONE$$v14$$x1932-6203$$y2019 000144615 909CO $$ooai:inrepo02.dkfz.de:144615$$pVDB 000144615 9101_ $$0I:(DE-588b)2036810-0$$6P:(DE-He78)79897f8897ff77676549d9895258a0f2$$aDeutsches Krebsforschungszentrum$$b0$$kDKFZ 000144615 9101_ $$0I:(DE-588b)2036810-0$$6P:(DE-He78)1042737c83ba70ec508bdd99f0096864$$aDeutsches Krebsforschungszentrum$$b2$$kDKFZ 000144615 9101_ $$0I:(DE-588b)2036810-0$$6P:(DE-HGF)0$$aDeutsches Krebsforschungszentrum$$b9$$kDKFZ 000144615 9101_ $$0I:(DE-588b)2036810-0$$6P:(DE-He78)ea098e4d78abeb63afaf8c25ec6d6d93$$aDeutsches Krebsforschungszentrum$$b15$$kDKFZ 000144615 9101_ $$0I:(DE-588b)2036810-0$$6P:(DE-He78)3d04c8fee58c9ab71f62ff80d06b6fec$$aDeutsches Krebsforschungszentrum$$b16$$kDKFZ 000144615 9131_ $$0G:(DE-HGF)POF3-315$$1G:(DE-HGF)POF3-310$$2G:(DE-HGF)POF3-300$$3G:(DE-HGF)POF3$$4G:(DE-HGF)POF$$aDE-HGF$$bGesundheit$$lKrebsforschung$$vImaging and radiooncology$$x0 000144615 9141_ $$y2019 000144615 915__ $$0StatID:(DE-HGF)0100$$2StatID$$aJCR$$bPLOS ONE : 2017 000144615 915__ $$0StatID:(DE-HGF)0200$$2StatID$$aDBCoverage$$bSCOPUS 000144615 915__ $$0StatID:(DE-HGF)0300$$2StatID$$aDBCoverage$$bMedline 000144615 915__ $$0StatID:(DE-HGF)0310$$2StatID$$aDBCoverage$$bNCBI Molecular Biology Database 000144615 915__ $$0StatID:(DE-HGF)0320$$2StatID$$aDBCoverage$$bPubMed Central 000144615 915__ $$0StatID:(DE-HGF)0501$$2StatID$$aDBCoverage$$bDOAJ Seal 000144615 915__ $$0StatID:(DE-HGF)0500$$2StatID$$aDBCoverage$$bDOAJ 000144615 915__ $$0StatID:(DE-HGF)0030$$2StatID$$aPeer Review$$bDOAJ : Peer review 000144615 915__ $$0LIC:(DE-HGF)CCBYNV$$2V:(DE-HGF)$$aCreative Commons Attribution CC BY (No Version)$$bDOAJ 000144615 915__ $$0StatID:(DE-HGF)0600$$2StatID$$aDBCoverage$$bEbsco Academic Search 000144615 915__ $$0StatID:(DE-HGF)0030$$2StatID$$aPeer Review$$bASC 000144615 915__ $$0StatID:(DE-HGF)0199$$2StatID$$aDBCoverage$$bClarivate Analytics Master Journal List 000144615 915__ $$0StatID:(DE-HGF)0111$$2StatID$$aWoS$$bScience Citation Index Expanded 000144615 915__ $$0StatID:(DE-HGF)0150$$2StatID$$aDBCoverage$$bWeb of Science Core Collection 000144615 915__ $$0StatID:(DE-HGF)1040$$2StatID$$aDBCoverage$$bZoological Record 000144615 915__ $$0StatID:(DE-HGF)1050$$2StatID$$aDBCoverage$$bBIOSIS Previews 000144615 915__ $$0StatID:(DE-HGF)9900$$2StatID$$aIF < 5 000144615 9201_ $$0I:(DE-He78)E010-20160331$$kE010$$lRadiologie$$x0 000144615 9201_ $$0I:(DE-He78)C060-20160331$$kC060$$lBiostatistik$$x1 000144615 980__ $$ajournal 000144615 980__ $$aVDB 000144615 980__ $$aI:(DE-He78)E010-20160331 000144615 980__ $$aI:(DE-He78)C060-20160331 000144615 980__ $$aUNRESTRICTED
