Men with negative prostate biopsy results face follow-up uncertainty. This study reviews factors like PSA velocity and density to guide decisions on repeat prostate biopsies.

Area of Science:

  • Urology
  • Oncology
  • Medical Diagnostics

Background:

  • Negative results from transrectal ultrasound-guided prostate biopsies create uncertainty regarding optimal patient follow-up.
  • Several biomarkers and factors have been investigated to enhance the detection of prostate cancer in initial and repeat biopsies.

Purpose of the Study:

  • To critically evaluate variables influencing prostate cancer detection after initial negative biopsies.
  • To develop an algorithm to aid in the decision-making process for repeat prostate biopsies.

Main Methods:

  • A Medline literature search was conducted using relevant Medical Subject Headings.
  • Pertinent articles were critically evaluated to synthesize existing data.
  • An algorithm was developed based on the accumulated evidence.

Main Results:

  • Key variables influencing repeat biopsy decisions include prostate-specific antigen (PSA) velocity, PSA density, free-percent PSA, and histological findings.
  • These factors can individually or collectively inform the need for further diagnostic procedures.

Conclusions:

  • The developed algorithm aims to standardize and improve the decision process for repeat prostate biopsies.
  • This approach assists clinicians in managing patients with initially negative prostate biopsy results, optimizing follow-up strategies.
