Summary
For localized prostate cancer, radical prostatectomy and brachytherapy show similar effectiveness for low- and intermediate-risk disease. High-risk patients may benefit more from external-beam radiation therapy with androgen deprivation.
Area of Science:
- Oncology
- Urology
Background:
- Radical prostatectomy and ultrasound-guided transperineal brachytherapy are primary treatments for localized prostate cancer.
- Direct comparative randomized trials are lacking, necessitating reliance on institutional data.
Purpose of the Study:
- To review and compare available data on radical prostatectomy and brachytherapy for localized prostate cancer.
- To discuss controversies in comparing these treatment modalities.
Main Methods:
- Review of major institutional series for radical prostatectomy and brachytherapy.
- Analysis of treatment outcomes based on disease risk stratification (low, intermediate, high).
Main Results:
- For low-risk prostate cancer, both treatments achieve >80% disease control with no clear superiority.
- For intermediate-risk prostate cancer, neither modality is definitively superior; brachytherapy with external-beam radiation therapy is suggested.
- For high-risk prostate cancer, neither radical prostatectomy nor brachytherapy consistently yields >50% biochemical control.
Conclusions:
- Radical prostatectomy and brachytherapy are comparable for low- and intermediate-risk localized prostate cancer.
- External-beam radiation therapy combined with androgen deprivation is currently the most effective option for high-risk prostate cancer.
