[PSA/volume ratio in prostatic disease in the elderly]
Recenti Progressi in Medicina
|November 7, 2001
Summary
Aging does not affect Prostate Specific Antigen (PSA) levels, but increased prostatic volume does. This suggests adjusted PSA ranges for elderly men with Benign Prostatic Hyperplasia (BPH).
Area of Science:
- Urology
- Andrology
- Biochemistry
Context:
- Prostate Specific Antigen (PSA) is a key biomarker for prostate diseases.
- Established PSA reference ranges may not be optimal for the elderly population.
- Benign Prostatic Hyperplasia (BPH) is common in older men and can affect PSA levels.
Purpose:
- To investigate the relationship between aging, PSA levels, and prostate volume.
- To determine if age-specific PSA reference ranges are warranted in elderly men.
- To assess the correlation between PSA, prostatic volume, and adenoma size.
Summary:
- Age showed no significant correlation with PSA levels or prostate volume.
- PSA levels strongly correlated with increased prostate volume and adenoma diameter.
- Free PSA levels were often in the gray zone, complicating diagnosis.
Impact:
- Findings suggest that elevated PSA in elderly men with BPH may not indicate malignancy.
- This study supports considering higher PSA thresholds (4-10 ng/ml) for benign conditions in older men with large prostates.
- The results advocate for incorporating prostate volume and free PSA into PSA interpretation for elderly patients.
