Adjuvant and Salvage Radiation Therapy for Prostate Cancer After Radical Prostatectomy

Although radical prostatectomy (RP) provides excellent cancer control, tumor recurrence occurred in approximately 15–40% of patients within 5 years usually with elevated prostate-specific antigen (PSA) level [1, 2]. Postoperative radiation therapy is recommended for patients with adverse risk factors after complete surgical resection, subclinical disease detected by elevated postoperative serum PSA, or clinical tumor recurrence in prostatic fossa.
