Keywords
Primary disease, multiparametric MRI, targeted prostate biopsy, MRI/ultrasound fusion-guided prostate biopsy, systematic transrectal ultrasound-guided prostate biopsy
Brief summary
Patients will be submitted to a multiparametric MRI examination of the prostate. Subsequently, all participants will be randomized (1:1) into both study arms. In study arm A patients will be submitted to the gold-standard which comprises systematic transrectal ultrasound-guided prostate biopsy. In study arm B patients will be submitted to targeted prostate biopsy based on the multiparametric MRI findings.
Detailed description
In men with previously negative prostate biopsy and persistent elevated prostate-specific antigen (PSA) value, it is unclear which biopsy strategy offers the highest detection rate for significant prostate cancer. The hypothesis of this study is that targeted MRI/ultrasound fusion-guided biopsy improves the detection rates of significant prostate cancers compared with systematic transrectal ultrasound-guided prostate biopsy. Men with at least one previously negative transrectal ultrasound-guided biopsy and persistently elevated PSA values (\> 3 ng/ml) or PSA velocity \>0.75 ng/ml/p.a. will be submitted to a multiparametric MRI examination of the prostate. Subsequently, all participants will be randomized (1:1) into both study arms. In study arm A patients will be submitted to the gold-standard which comprises systematic transrectal ultrasound--guided prostate biopsy. In study arm B patients will be submitted to targeted prostate biopsy based on the multiparametric MRI findings. Targeted biopsies will be performed using MRI/ultrasound fusion-guided.
Interventions
