Robot-assisted radical prostatectomy (RARP) and laparoscopic radical prostatectomy (LRP) show similar rates of positive surgical margins (PSMs). This finding holds true even in medium-volume centers, suggesting surgical experience is key.
Area of Science:
- Urology
- Surgical Oncology
Background:
- Positive surgical margins (PSMs) are a critical indicator of oncological outcomes in radical prostatectomy (RP).
- Comparing PSM rates between different surgical techniques is essential for optimizing patient care.
Purpose of the Study:
- To evaluate and compare the incidence of PSMs between laparoscopic radical prostatectomy (LRP) and robot-assisted radical prostatectomy (RARP).
- To analyze the correlation between surgical technique, nerve-sparing approach, and PSMs, stratified by pathological stage, in medium-case-load centers.
Main Methods:
- Retrospective analysis of 1992 patients who underwent radical prostatectomy (RP).
- Evaluation and comparison of the overall and stage-related incidence of PSMs between LRP and RARP.
Main Results:
- No statistically significant difference was found in the overall incidence of PSMs between LRP and RARP.
- PSM rates were notable in pT3 stages for both techniques, especially when compared to high-volume centers.
Conclusions:
- RARP and LRP demonstrate comparable rates of PSMs in medium-volume urologic centers.
- Surgical experience and patient selection may influence PSM rates, particularly in advanced pathological stages (pT3).
