Impact of positive surgical margin location on biochemical recurrence in pT3 prostate cancer after robot-assisted radical prostatectomy: a retrospective cohort study

Key Points

• The study aims to determine the impact of positive surgical margin characteristics on biochemical recurrence in patients with pT3 prostate cancer following robotic surgery.
• Conducted a retrospective cohort analysis of prostate cancer patients
• Evaluated the relationship between positive surgical margin features and biochemical recurrence
• Examined factors such as margin length, tertiary pattern presence, and apical involvement
• Positive surgical margin location did not determine biochemical recurrence rates.
• Positive surgical margin length, presence of a tertiary pattern, and apical involvement were significant indicators.
• Detailed reporting of margin characteristics improved postoperative treatment decisions.
