The 5- and 7-year biochemical recurrence-free rates were 52.6% and 47.9%, respectively. Multivariate analysis revealed the following independent risk factors for recurrence after SRT: higher total Gleason score (\u22658), higher pathological T stage, negative resection margin, and shorter period between radical prostatectomy and biochemical recurrence-free. The cumulative incidence rates of grade 2 or higher genitourinary and gastrointestinal adverse events after SRT were 27.4% and 9.4%, respectively. Bowel function worsened after SRT and showed significant deterioration 5\u00a0years after SRT, compared with pre-treatment. Five years post SRT, the rates of patients whose physical and mental component scores were\u00a0&amp;lt;\u00a050 were 44.1% and 34.3%, respectively.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusions<\/jats:title>\n                  <jats:p>Prostate-specific antigen recurrence occurred in approximately half of the patients after SRT, with a higher Gleason score, higher pathological T stage, negative resection margin, and shorter period between radical prostatectomy and first biochemical recurrence identified as risk factors. Besides the adverse events, careful attention to long-term quality-of-life deterioration must be considered when considering indications for SRT.<\/jats:p>\n
