This single institutional study is aimed to observe the outcome of patientswho received postoperative radiotherapy after radical prostatectomy. MATERIALS AND
After median follow-up of 53 months (range, 0 to 104 months), the 5-year bRFS of all patients was estimated 80.4%. The 5-year OS was estimated 96.6%. Patientswho were given androgen deprivation therapy had a 5-year bRFS of 95.1% while the ones who were not given any had that of 40.0% (p < 0.01). However, the statistical significance in survival difference did not persist in multivariate analysis. The 3-year actuarial grade 3 chronic toxicity was 1.7% and no grade 3 acute toxicity was observed.
CONCLUSION:
The biochemical and toxicity outcome of post-radical prostatectomyradiotherapy in our institution is favorable and comparable to those of other studies.
