Salvage radiotherapy for PSA failure after radical prostatectomy
1Department of Radiation Oncology, Princess Margaret Hospital, 620 University Avenue, Toronto, Ontario, Canada M5G 2M9.
Summary
Salvage radiation therapy to the prostatic bed may offer a cure for prostate-specific antigen (PSA) failure after prostatectomy. Early treatment appears more effective, but evidence quality is limited.
Area of Science:
- Oncology
- Radiation Oncology
- Urologic Oncology
Background:
- Prostate-specific antigen (PSA) failure post-radical prostatectomy is common.
- Management strategies lack consensus.
- Salvage radiation to the prostatic bed is a potential curative option.
Purpose of the Study:
- Review the efficacy and toxicity of salvage radiation therapy.
- Discuss patient selection criteria.
- Provide recommendations for clinical practice and future research.
Main Methods:
- MEDLINE search (1989-2000) using MeSH terms 'prostatic neoplasms' and 'radiotherapy'.
- Reviewed 660 abstracts, selecting articles on post-operative radiation to the prostatic bed.
- Included 22 case series (1062 patients) for efficacy review, excluding adjuvant radiation studies.
Main Results:
- Limited evidence quality hinders definitive judgment on salvage radiation efficacy.
- Efficacy may be higher when salvage radiation is administered earlier rather than later.
- Difficult to assess outcomes, especially for PSA levels between 0.01-0.2 ng/ml.
Conclusions:
- The effectiveness of salvage radiation for PSA failure needs further investigation.
- Timing of salvage radiation is a critical factor.
- Findings impact the interpretation of adjuvant radiation trials.
