Comparison of TB+PB and TB+6SB for Prostate Cancer Diagnosis

Summary

The goal of this randomized controlled trial (RCT) is to evaluate the diagnostic efficacy of two novel prostate biopsy schemes, including targeted and perilesional biopsy (TB+PB) and combination of sextant-systematic biopsy and targeted biopsy (TB+6SB). The main questions it aims to answer are: Does TB+PB promote the accurate diagnosis of clinically significant prostate cancer (csPCa)? Could TB+6SB achieve the non-inferior diagnostic efficacy compared to TB+PB scheme? What's the value of TB+6SB in improving the detection of prostate cancer in the negative prostate lobe (contralateral to the index lesion)? In the era of MRI-targeted biopsy (TB), when TB and PB is effectively conducted and allows confident detection of the ROI, do we still need to perform SB? Researchers will compare the cancer detection rates of TB+PB and TB+SB to explore the efficacy of different prostate biopsy schemes. They will evaluate the diagnostic profile of different prostate biopsy schemes through the spatial analysis of the prostate. Participants will: Receive TB+PB or TB+6SB.
