Summary

Transrectal ultrasound-guided prostate biopsies are recommended for suspected cancer. Extended biopsy schemes improve cancer detection, while saturation biopsies are reserved for repeat procedures when initial results are negative but suspicion remains high.

Area of Science:

  • Urology
  • Oncology
  • Medical Imaging

Background:

  • Transrectal ultrasound-guided biopsy is standard for suspected prostate cancer.
  • Effective pain management, such as periprostatic nerve blocks with lidocaine, is crucial.
  • Current biopsy protocols aim to maximize cancer detection while minimizing adverse events.

Purpose of the Study:

  • To outline optimal strategies for transrectal ultrasound-guided prostate biopsy.
  • To detail recommended biopsy schemes for initial and repeat procedures.
  • To clarify the role of different biopsy techniques in prostate cancer diagnosis.

Main Methods:

  • Systematic biopsy with a minimum of 10 laterally directed cores.
  • Extended biopsy schemes focusing on specific prostate zones (base, apex).

Use of Magnetic Resonance Imaging and Biopsy Data to Guide Sampling Procedures for Prostate Cancer Biobanking

Published on: October 10, 2019

  • Consideration of saturation biopsies (>=20 cores) for select repeat cases.

    • Main Results:

    • Extended biopsy schemes demonstrate higher cancer detection rates.
    • Transition zone biopsies show low detection rates on initial sampling.
    • Saturation biopsies are effective for repeat sampling in specific clinical scenarios.

    Conclusions:

    • Systematic and extended biopsy schemes are recommended for initial prostate cancer detection.
    • Transition zone biopsies are generally not advised for initial sampling.
    • Saturation biopsies are a valuable tool for repeat sampling when initial biopsies are negative but clinical suspicion persists.
