Summary
Transurethral resection of the prostate (TURP) significantly lowers prostate-specific antigen (PSA) levels. Post-TURP PSA monitoring is crucial, as rising levels in patients with benign prostatic hyperplasia may indicate prostate cancer.
Area of Science:
- Urology
- Oncology
- Biochemistry
Background:
- Prostate-specific antigen (PSA) is a key biomarker for prostate health.
- Transurethral resection of the prostate (TURP) is a common procedure for benign prostatic hyperplasia (BPH).
- The impact of TURP on post-operative PSA levels requires clarification.
Purpose of the Study:
- To evaluate the effect of TURP on serum PSA concentrations.
- To determine if PSA reference ranges need adjustment after TURP.
- To assess the utility of PSA monitoring in identifying prostate cancer post-TURP.
Main Methods:
- Retrospective analysis of 55 patients undergoing TURP for BPH.
- PSA levels measured pre-operatively and every 6 months for 48 months post-TURP.
- Comparison with 12 patients who underwent radical perineal prostatectomy (RPP) with prior TURP.
Main Results:
- Median PSA decreased from 4.9 ng/ml to 0.6 ng/ml 48 months post-TURP.
- Patients who later developed prostate cancer (CaP) had higher pre-TURP PSA (6.8 ng/ml) and less reduction (2.2 ng/ml).
- PSA levels began to rise before CaP diagnosis in the RPP group.
Conclusions:
- TURP leads to a sustained decrease in PSA levels to below 2 ng/ml in patients with benign disease.
- A rising PSA post-TURP warrants investigation for potential prostate cancer.
- Current PSA monitoring protocols may need consideration for post-TURP patients.
