Review reveals novel serum and urine biomarkers to supplement PSA screening in men, highlighting their potential to reduce unnecessary biopsies and overdiagnosis.

Key Points

To review the diagnostic limitations of conventional prostate-specific antigen testing and evaluate emerging serum and urinary biomarkers for early prostate cancer detection.
Literature review analyzing the performance and diagnostic accuracy of standard prostate-specific antigen (PSA) screening across different concentration thresholds.
Evaluation of secondary serum markers, including free PSA, PSA density, PSA velocity, complexed PSA, intact PSA, proPSA, human glandular kallikrein 2, and insulin-like growth factor 1.
Assessment of novel urinary markers such as glutathione-S transferase P1 (GSTP-1), 8-OHdG, DD3/uPM3, and telomerase for early cancer identification.
Standard PSA screening exhibits low predictive value in the 4.0 to 10.0 ng/ml range and correlates poorly with tumor grade and stage.
Clinically significant prostate cancers frequently occur at serum PSA concentrations below 4.0 ng/ml, leading to frequent false negatives alongside widespread overdiagnosis and unnecessary biopsies.
Novel molecular derivatives and urine-based gene targets such as GSTP-1, DD3, and telomerase offer increased specificity to enhance screening accuracy.
