Summary
Radical perineal prostatectomy (RPP) can be safely performed without lymphadenectomy in select prostate cancer patients. Identifying low-risk factors allows for reduced morbidity while maintaining oncological outcomes.
Area of Science:
- Urology
- Oncology
- Surgical Oncology
Background:
- Radical perineal prostatectomy (RPP) is a treatment for localized prostate cancer.
- Staging lymphadenectomy is often performed to assess lymph node involvement but increases morbidity.
- Identifying patients who can safely avoid lymphadenectomy is crucial for optimizing treatment outcomes.
Purpose of the Study:
- To establish criteria for selecting prostate cancer patients eligible for RPP without prior staging lymphadenectomy.
- To reduce treatment-related morbidity while preserving oncological principles.
Main Methods:
- Retrospective analysis of 88 patients undergoing RPP.
- Identification of a low-risk group defined by clinically localized prostate cancer, Gleason score ≤7, and PSA ≤10 ng/ml.
- Comparison of outcomes between patients who underwent staging lymphadenectomy and those who did not.
Main Results:
- 17 out of 88 patients (19.3%) met the low-risk criteria and were node-negative (pN-).
- Subsequent patients meeting these criteria (n=17) underwent RPP without lymphadenectomy, with a 17.6% positive margin rate and maintained PSA levels.
- Approximately 38.6% of the overall series could have potentially avoided lymphadenectomy based on these criteria.
Conclusions:
- RPP without prior staging lymphadenectomy is a viable option for select patients with clinically localized prostate cancer, PSA ≤10 ng/ml, and Gleason score ≤7.
- This approach can be applied to approximately 40% of patients recommended for radical prostatectomy, reducing unnecessary morbidity.
