The primary aim of STHLM3-MR/Fusion is to increase the specificity in early detection of prostate cancer without decreasing the sensitivity of aggressive prostate cancers by introducing targeted prostate biopsies and comparing to traditional prostate biopsies. The primary endpoints are the number of performed biopsies and the number of detected high-grade prostate cancers defined as Gleason 7 or higher. Secondary endpoints include the number of low risk prostate cancers diagnosed and the proportion of patients with up-or downgraded disease after assessment of prostatectomy specimen. Additional aims include to assess the health economic consequences of implementing MRI based prostate cancer diagnostics and to improve the quality and effectiveness of prostate cancer diagnosis in the routine health care in Stockholm.
