Pathological features of prostate cancer in men treated with robot-assisted radical prostatectomy in the Middle East

Abstract

Little is known about the pathological features of radical prostatectomy among men living in the Middle East. Although prostate cancer became the most common malignancy among males in some countries in the Middle East, the incidence is much lower compared to western populations. The aim of this study is to analyze pathological features and biochemical recurrence in men who underwentrobotic-assisted radicalprostatectomy(RARP) in Kuwait. The data on all RARP cases performed by a uro-oncologist (SA) were recorded. A comprehensive database was collected, including demographic, clinical, and pathological data. Between February 2014 and November 2019, 65 RARP cases were performed out of a total of 200 robotic urological procedures. The median follow-up was 41.5months [inter quartile range (IQR) 27.6-52.7]. Eleven (17%) complications occurred in 7 patients, 64% were early (< 30days post-operatively) and minor (Clavien I-II). Thirty-five (54%) patients had ≥ pT3 disease. Overall, 12 (18%) patients had a positive surgical margin (PSM), and all had ≥ pT3 disease. Potency and continence rates at 12months were 82% and 97%, respectively. The mean and SD of the hospital stay were 2.7 ± 1.1days. Biochemical recurrence (BCR) rate was 10%. Men with prostatic adenocarcinoma treated with RARP in Kuwait show a high incidence of pT3 disease. PSM and BCR rates were similar to multiple reports in the literature. To our knowledge, this is the first report of RARP pathological outcomes in the gulf cooperation council (GCC) region of the Middle East.
