Abstract
To present multinational experience in robot-assisted radical prostatectomy (RARP) by fellowship-trained expertise in low-volume regions in Gulf Cooperation Council (GCC) countries and to compare the current results with global outcomes reported in recent meta-analyses. A retrospective review of prospectively collected data was performed for patients undergoing RARP for localized prostate cancer (PCa). Three fellowship-trained surgeons at four academic and referral centers in Saudi Arabia and Kuwait performed all procedures between February 2014 and December 2019. Data on demographics, perioperative characteristics, pathology, and adverse events were collected. A total of 207 patients were included with a median (IQR) follow-up duration of 28 (15-38) months. The median prostate volume and prostate-specific antigen were 42 (32-53) g and 9.1 (5.8-14.1) ng/mL, respectively. While 65.2% of patients had a Gleason score ≥7, 20% had grade group 4 disease, and 7.8% had ≥cT3 disease. The mean ± SD operative time was 203 ± 52 minutes, and the mean estimated blood loss was 158 ± 107 mL. Only 4 (1.9%) patients received perioperative blood transfusions. Positive surgical margins were observed in 21.7% of patients, all of whom had ≥pT3 disease. There were 23 complications in 18 (8.7%) patients, including Clavien-Dindo grade III complications in 2.4%. At the 12-month follow-up, 35.8% of patients were potent, 94.6% were continent, and 9.2% had biochemical recurrence. The safety and efficacy of RARP by fellowship-trained expertise in GCC countries were well established. The outcomes seem promising and comparable to international centers and should improve with increasing case volume and fellowship-trained expertise.
