Hypothesis
To assess the efficacy of salvage radiotherapy (RT) for persistent or rising PSA after radical prostatectomy and to determine prognostic factors identifying patients who may benefit from salvage RT.
Conclusion
When delivered early, RT is an effective treatment after radical prostatectomy, with preRT PSA ≥1 ng/ml predicting relapse.
Supporting Evidence
- The 3-year and 5-year biochemical disease-free survival (bDFS) rates were 56.1% and 41.2%, respectively.
- PreRT PSA ≥1 ng/ml was the only factor associated with biochemical relapse.
- Patients with preRT PSA <1 ng/ml had a significantly higher bDFS compared to those with PSA ≥1 ng/ml.
Takeaway
This study shows that giving radiation therapy early after prostate surgery can help keep cancer from coming back, especially if the PSA level is low.
Methodology
The study reviewed records of 59 patients who underwent RT for biochemical relapse after radical prostatectomy, analyzing various predictive factors.
Potential Biases
Potential biases may arise from the retrospective nature of the study and the lack of randomization.
Limitations
The study is limited to a single institution and may not be generalizable to all patient populations.
Participant Demographics
Patients had a median age of 62 years, with a range from 46 to 76 years.
