To assess the perioperative and short-term functional and oncologic outcomes of the salvage robot-assisted radical prostatectomy (sRARP), after recurrence following primary proton beam therapy for clinically localized prostate cancer. Ten patients undergoing sRARP after failure of the prior definitive proton beam therapy for localized prostate cancer were included. BCR is defined as a prostate-specific antigen (PSA) value of 2.0 ng/mL greater than the absolute nadir. All of the individuals had a diagnosis of prostate cancer via biopsy after proton beam therapy, with negative findings on magnetic resonance imaging/computer tomography of the pelvis and abdomen, and a bone scan. The sRARP procedure with pelvic lymph node dissection was performed by a single surgeon in all patients. The median age of the cohort at sRARP was 66.8 years, and the mean BMI was 29.2 kg/m2. The mean duration from proton beam therapy to sRARP was 58.4 months; the mean preoperative PSA level was 5.5 ng/mL, the mean operative time was 230 minutes, and the approximate blood loss was 745 mL. Anastomotic leakage occurred in half of the individuals, and bladder neck contracture developed in 6 patients. For 8 patients, the continence results within 6 months followup were available. Overall, 24 complications occurred in 9 patients. At follow-up in the 32nd month, the overall survival rate was 80%, and the BCR-free survival rate was 90%. sRARP after proton beam therapy is an applicable procedure, but has a high risk of serious complications.
