Micro-Ultrasound–Guided vs Multiparametric Magnetic Resonance Imaging-Targeted Biopsy in the Detection of Prostate Cancer: A Systematic Review and Meta-Analysis

PURPOSE: Micro-ultrasound is a novel high resolution ultrasound technology aiming to improve prostate imaging and, consequently, the diagnostic accuracy of ultrasound-guided prostate biopsy. Micro-ultrasound-guided prostate biopsy may present comparable detection rates to the standard of care multiparametric magnetic resonance imaging-targeted prostate biopsy for the diagnosis of clinically significant prostate cancer. We aimed to compare the detection rate of micro-ultrasound vs multiparametric magnetic resonance imaging-targeted prostate biopsy for prostate cancer diagnosis. MATERIALS AND METHODS: We performed a systematic review and meta-analysis of diagnostic accuracy studies comparing micro-ultrasound-guided prostate biopsy to multiparametric magnetic resonance imaging-targeted prostate biopsy as a reference standard test (PROSPERO ID: CRD42020198326). Records were identified by searching in PubMed®, Scopus® and Cochrane Library databases, as well as in potential sources of gray literature until November 30th, 2020. RESULTS: =0%). CONCLUSIONS: Micro-ultrasound-guided prostate biopsy provides comparable detection rates for prostate cancer diagnosis with the multiparametric magnetic resonance imaging-guided prostate biopsy. Therefore, it could be considered as an attractive alternative to multiparametric magnetic resonance imaging-targeted prostate biopsy. Nevertheless, high quality randomized trials are warranted to corroborate our findings.
