JO - PLOS ONE VL - 14 IS - 8 SN - 1932-6203 CY - San Francisco, California, US PB - PLOS M1 - DKFZ-2019-02057 SP - e0221350 - PY - 2019 AB - Risk models (RM) need external validation to assess their value beyond the setting in which they were developed. 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 LB - PUB:(DE-HGF)16 C6 - pmid:31450235 DO - DOI:10.1371/journal.pone.0221350 UR - https://inrepo02.dkfz.de/record/144615 ER -
