6. Screening

7. What is PSA (Prostate Specific
Antigen)?
• A Serine protease (enzyme)
found in the prostate
• Secreted by prostate
epithelial cells
• Found in ejaculate
• As diagnostic tool for:
– Screening
– Staging
– Prognostic indicator
– Surveillance

10. Free/Total PSA Ratio:
A Way to Improve Specificity
• Prostate cancer maybe associated with more protein-bound
PSA (less free PSA) than in BPH
– F/T ratio is lower in patients with prostate cancer
– Can improve test specificity
– Useful when total PSA in 4-10 ng/ml range

11. Digital Rectal Examination
– DRE (digital rectal exam)
has a 50% positive
predictive value
–DRE alone is not a
good screening
tool
– BUT it is an important
part of screening
