Evaluation of Perilesional Biopsy in Diagnosis of Prostate Cancer: a Multicenter Randomized Controlled Trial
The goal of this multicenter randomized controlled trial (RCT) is to evaluate the efficacy of different prostate biopsy schemes, including perilesional biopsy (PB) and combination of systematic biopsy and targeted biopsy (TB+SB). The main questions it aims to answer are: Does PB promote the accurate diagnosis of clinically significant prostate cancer? What's the value of PB in improving the safety of prostate biopsy? Researchers will compare the cancer detection rates of PB and TB+SB to explore the efficacy of different prostate biopsy schemes. Participants will: Receive TB+PB or TB+SB.
• The age of the patient is between 45 and 85.
• No previous biopsy.
• Patients with single suspicious lesion, complete MRI data, qualified image quality control, suspicious lesions, and Prostate Imaging Reporting and Data System version 2.1 (PI-RADS V2.1) of \> 3.
• Patients were in accordance with the indication of prostate biopsy, including patients with suspicious prostate nodes found by digital rectal examination (DRE), the suspicious lesions found by transrectal ultrasound (TRUS) or MRI, total prostate-specific antigen (tPSA) \>10ng/mL, tPSA 4-10ng/mL with free-to-total PSA ratio (f/tPSA) \<0.16 or PSA density (PSAD) \>0.15.
• The prostate biopsy pathological results were complete. The time interval between prostate biopsy and prostate MRI examination should not exceed one month.
• Patients with complete clinical information.
