Additionally, the BCN-MRI PM is validated in men receiving 5-alpha reductase inhibitors (5-ARI). Materials and methods : A population of 2,212 men with prostate-specific antigen serum level > 3.0 ng/ml and/or a suspicious digital rectal examination who underwent multiparametric MRI and targeted and/or systematic biopsies in the year 2022, at ten participant centers of the Catalonian csPCa early detection program, were selected. 120 individuals (5.7%) were identified as receiving 5-ARI treatment for longer than a year. The risk of csPCa was retrospectively assessed with the Barcelona-risk calculator 2 (BCN-RC 2). Men undergoing 5-ARI treatment for less than a year were excluded. CsPCa was defined when the grade group was ≥ 2. Results: The area under the curve of the BCN-MRI PM in 5-ARI naïve men was 0.824 (95% CI 0.783–0.842) and 0.849 (0.806–0.916) in those receiving 5-ARI treatment, p 0.475. Specificities at 100, 97.5, and 95% sensitivity thresholds were to 2.7, 29.3, and 39% in 5-ARI naïve men, while 43.5, 46.4, and 47.8%, respectively in 5-ARI users. The application of BCN-MRI PM would result in a reduction of 23.8% of prostate biopsies missing 5% of csPCa in 5-ARI naïve men, while reducing 25% of prostate biopsies without missing csPCa in 5-ARI users. Conclusions The BCN-MRI PM has achieved successful validation in Catalonia and, notably, for the first time, in men undergoing 5-ARI treatment. 000136191 536__ $$9info:eu-repo/grantAgreement/ES/ISCIII/PI20/01666 000136191 540__ $$9info:eu-repo/semantics/openAccess$$aby$$uhttp://creativecommons.org/licenses/by/3.0/es/ 000136191 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000136191 700__ $$0(orcid)0000-0003-0178-4567$$aBorque-Fernando, Ángel$$uUniversidad de Zaragoza 000136191 700__ $$0(orcid)0000-0002-3007-302X$$aEsteban, Luis M. 000136191 700__ $$aPicola, Natàlia 000136191 700__ $$aMuñoz-Rodriguez, Jesús 000136191 700__ $$aPaesano, Nahuel 000136191 700__ $$aRuiz-Plazas, Xavier 000136191 700__ $$aMuñoz-Rivero, Marta V. 000136191 700__ $$aCelma, Ana 000136191 700__ $$aManuel, Gemma García-de 000136191 700__ $$aMiró, Berta 000136191 700__ $$aAbascal, José M. 000136191 700__ $$aServian, Pol 000136191 7102_ $$11013$$2817$$aUniversidad de Zaragoza$$bDpto.
