On the relationship between various anticoagulants and robot-assisted radical prostatectomy: a single-surgeon serial analysis

Background: and Objectives: Prostate cancer patients often have other health conditions and take anticoagulants. It was believed that surgery under anticoagulants could worsen surgical results. This study aims to explore the safety of robot-assisted prostatectomy in anticoagulated patients, without any exclusion criteria. Methods: The study included 500 patients who underwent RARP by a single surgeon between April 2019 and August 2022. Patients were divided into two groups: Group 1, consisting of 376 men (75.2%), did not receive any anticoagulation, while Group 2, with 124 patients (24.8%), received different forms of anti-coagulation. Then the anti-coagulation group was divided into 4 subgroups according to their definite anti-coagulation. The aspirin 15,6%, new oral anticoagulants (NOAC) 5,4%, Vitamin K antagonist (VKA) 2%, and dual antiplatelet therapy (DAPT) 1,8% subgroup. postoperative complications and readmission rates were compared between the two study groups and subgroups. Key findings : Patients in the combined group 2 were older and they also carried more comorbidities compared to men in group 1 (p=0.03, p=0.001).The study groups had similar oncological results, with 40.4% of patients having locally advanced cancers. Catheter days were longer in the anticoagulation group (4,5 vs 4 days, p=0.001). No significant differences were observed between study groups for overall, minor, and major complications (p= 0.160, 0.100, and 0.915 respectively). Additionally, readmissions were low (5.6%) and similar between study groups (p=0.635). Conclusion: under cautious management, RARP under diverse anti-coagulation regimes is safe and has comparable results to men with no medications. Further prospective studies must be conducted to confirm our findings.
