134 Background: Robot-assisted radical prostatectomy (RARP) has become one of standard treatments for localized prostate cancer. However, a feasibility of RARP in elderly patients has not been clear yet. We performed a comparative analysis of peri-surgical/oncological outcomes for younger and elderly patients underwent RARP. Methods: We reviewed and compared our initial 340 consecutive patients who underwent RARP from 9/2012 to 8/2015 for peri-surgical outcomes, including surgical times, blood loss, complications, pathological findings, continence recovery, and oncological outcomes stratified by age less than 70 and over 70 years. Results: In our cohort, 202 men were age less than 70 and 138 men were ≥70. Preoperative parameters (age, PSA, Gleason score) were similar in both younger and elder groups. Operative time (median: 167 vs. 171 minutes) and estimated blood loss were similar in both groups. One of elder patients (0.7%) needed transfusion. Peri/post-operative complications in both groups appeared to be minimal with no cases of intra-operative open conversion. One of younger patients needed a surgical settlement for port site herniation. Surgical positive margin rates in organ-confined (pT2) disease were also similar (5.6%, younger vs. 9.0%,elder). Continence at 3 months was 82% in elder patients as opposed to 87% in younger patients. Median follow-up period in in elder patients and younger patients were 15.2 and 15.3 months, respectively. Biochemical recurrence free survival rates in elder patients and younger patients were 89.9% and 93.6%, respectively (p=0.1026). Conclusions: In our study, RARP in elderly patients was relatively safe and yielded good oncologic results. RARP is feasible even in elderly patients.
