Summary
Elevated prostate-specific antigen (PSA) levels can occur with bacterial prostatitis. PSA levels normalize after treatment for acute inflammation, but persistent elevation may indicate prostate cancer.
Area of Science:
- Urology
- Oncology
- Infectious Diseases
Background:
- Prostate-specific antigen (PSA) is a key tumor marker for prostate cancer diagnosis and monitoring.
- Elevated PSA levels are generally specific for prostate cancer, but can also be slightly elevated in benign prostatic hyperplasia and bacterial prostatitis.
Purpose of the Study:
- To investigate PSA levels in patients with acute and chronic bacterial prostatitis.
- To determine the impact of prostatitis inflammation on PSA levels and its diagnostic implications for prostate cancer.
Main Methods:
- Serum PSA levels were measured in patients diagnosed with acute and chronic bacterial prostatitis.
- PSA levels were monitored in six patients with acute prostatitis and elevated PSA during antimicrobial therapy.
- Transrectal ultrasonography and biopsy were used to investigate persistent PSA elevation in a chronic prostatitis case.
Main Results:
- PSA levels were elevated during the acute phase of bacterial prostatitis.
- In all six acute prostatitis patients, PSA levels normalized within 14 days of antibiotic treatment.
- One patient with chronic prostatitis had persistent elevated PSA post-antibiotics, later diagnosed with adenocarcinoma.
Conclusions:
- Markedly elevated serum PSA in bacterial prostatitis can mimic prostate cancer, leading to diagnostic confusion.
- PSA testing should be performed after complete resolution of prostatic inflammation to accurately exclude malignancy.
