Summary
Granulomatous prostatitis can cause mild, temporary increases in prostate-specific antigen (PSA) levels. These PSA levels typically normalize as the inflammation resolves, aiding in differential diagnosis.
Area of Science:
- Urology
- Pathology
- Inflammatory Diseases
Background:
- Granulomatous prostatitis is an inflammatory condition.
- It can clinically mimic prostate cancer.
- Accurate diagnosis is crucial for patient management.
Purpose of the Study:
- To evaluate serum prostate-specific antigen (PSA) levels.
- To assess PSA changes in patients with granulomatous prostatitis.
- To differentiate from prostate malignancy.
Main Methods:
- Study included 10 patients with confirmed granulomatous prostatitis.
- Serum PSA levels were measured before and after diagnosis.
- Patients' age ranged from 53 to 80 years.
Main Results:
- Six patients had normal PSA (< 4.0 ng/mL) at diagnosis.
- Four patients showed slightly elevated PSA (4.0-6.0 ng/mL or 10.1 ng/mL).
- Six patients experienced a >40% PSA decrease within 6-12 months; all normalized by follow-up.
Conclusions:
- Granulomatous prostatitis can cause mild, transient PSA elevations.
- PSA levels normalize as inflammation subsides.
- This aids in distinguishing inflammatory prostatitis from prostate cancer.
