Obesity leads to a higher rate of positve surgical margins in the context of robot-assisted radical prostatectomy. Results of a prospectve multcenter study

Dec. 3, 2020 Introduction Current results concerning the effect of body mass index (BMI) on positive surgical margins (PSMs) after robot-assisted radical prostatectomy (RARP) in patients with localized prostate cancer are inconsistent. [...]the aim of this study was to further analyse the association between BMI and PSMs after RARP. Key Words: prostate cancer radical prostatectomy robotic surgery body mass index localisation of positive surgical margins extent of positive surgical margins INTRODUCTION Robot-assisted radical prostatectomy (RARP) using the da Vinci Surgical System (Intuitive Surgical Inc., Sunnyvale, CA, USA) was performed for the first time in the year 2000 by Jochen Binder in Frankfurt/Main (Germany) [1]. According to the World Health Organisation (WHO), in the year 2016, 39% of men worldwide were overweight (body mass index (BMI) more than 25 kg/m^sup 2^) and 11% of men were obese (BMI more than 30 kg/m^sup 2^) [4]. According to the anatomical location, PSMs were classified as posteriolateral (left and right), posterior, anterior, bladder neck and apical.
