Regional Versus Systematic Biopsy in Addition to Targeted Biopsy

Description
Summary:BACKGROUND AND OBJECTIVE: Intensification of targeted biopsy (TBx) around a magnetic resonance imaging (MRI)-visible lesion with regional biopsy (RBx) could obviate the need for systematic biopsy (SBx). We aimed to compare the detection yields of clinically significant prostate cancer (csPCa)-defined as International Society of Urological Pathology (ISUP) grade group ≥2-between TBx + RBx and the reference standard (TBx + SBx). METHODS: RBx was defined as perilesional or ipsilateral biopsy. A literature search was conducted up to September 2023 using PubMed, Embase, and Web of Science databases. The Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines were followed. Included studies were eligible when presenting data from SBx, TBx, and TBx + RBx cores and their detection yields. The Quality Assessment of Diagnostic Accuracy Studies (QUADAS-2) criteria were used to assess the risk of bias of the included studies. KEY FINDINGS AND LIMITATIONS: Twenty-one studies were included for a meta-analysis. The overall detection yield of csPCa was not statistically different between TBx + SBX and TBx + RBx (46.1% vs 44.2%; odds ratio [OR] 1.07, 95% confidence interval [CI] 0.99-1.16, p = 0.07); similar findings were found also for ISUP grade group ≥3 prostate cancer (PCa; OR 1.06, 95% CI 0.92-1.22, p = 0.43) and in different subgroup analyses. TBx + SBx was associated with higher cancer detection of ISUP grade group 1 PCa (OR 1.16, 95% CI 1.04-1.30, p = 0.008). The main limitations include the retrospective nature of most of the selected studies, heterogeneity of RBx definition, and template. CONCLUSIONS AND CLINICAL IMPLICATIONS: Our study supports the use of the TBx + RBx template in the early detection pathway for the detection of csPCa. SBx can be omitted when targeting lesions visible on MRI. PATIENT SUMMARY: A prostate biopsy strategy consisting of taking biopsy in and around an magnetic resonance imaging-visible lesion reduces the risk of detecting indolent prostate cancers without affecting the detection of aggressive tumours.
