Prostate-Specific Antigen (PSA) is an effective marker for prostate cancer, aiding in diagnosis, monitoring, and prognosis. While not tumor-specific, its clinical utility is significant, though further research is needed for optimal patient management.

Area of Science:

  • Urology
  • Oncology
  • Biomarker Discovery

Background:

  • Prostate cancer diagnosis and management require reliable markers.
  • Prostate-Specific Antigen (PSA) has emerged as a key biomarker.

Purpose of the Study:

  • To review the clinical utility of PSA in prostate cancer.
  • To identify the strengths and limitations of PSA as a diagnostic and monitoring tool.

Main Methods:

  • Literature review of studies on PSA in prostate cancer.
  • Analysis of PSA's organ-site and cell-type specificity.

Main Results:

  • PSA is a valuable marker for monitoring therapeutic efficacy, screening, early diagnosis, prognosis, staging, and detecting recurrent disease.

  • PSA is not tumor-specific, and its role in differentiating clinically significant from indolent cancer requires further investigation.

    • Conclusions:

    • PSA is the marker of choice for prostate cancer due to its specificity.
    • Combination of PSA, rectal examination, and biopsy is recommended for optimal detection and management.
    • Further studies are needed to address remaining questions regarding PSA's application and the assessment of tumor cell malignancy.
