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.

Abstract

PSM localization alone is not a determinant of BCR; however, PSM length, the presence of a tertiary pattern, and apical involvement provide clinically meaningful prognostic information. Therefore, detailed reporting of margin characteristics in pathology reports is critically important for accurately guiding postoperative treatment strategies.
