Summary
Three-dimensional AI-AR guidance in robot-assisted radical prostatectomy significantly improved margin control by enabling precise biopsies. This advanced technology led to lower positive surgical margins and better patient continence recovery.
Area of Science:
- Urology
- Surgical Technology
- Oncology
Background:
- Robot-assisted radical prostatectomy (RARP) is a key treatment for prostate cancer.
- Enhancements in surgical guidance are crucial for improving outcomes.
- Three-dimensional (3D) augmented reality (AR) and artificial intelligence (AI) offer new possibilities for intraoperative guidance.
Purpose of the Study:
- To evaluate if 3D-AI-AR guidance reduces positive surgical margins (PSMs) during RARP compared to standard 2D MRI guidance.
- To assess the impact of 3D-AI-AR guidance on oncological and functional outcomes.
Main Methods:
- A prospective, multicenter randomized controlled trial involving 133 patients with specific MRI findings.
- Patients were randomized to either 2D MRI-guided (n=84) or 3D-AI-AR-guided RARP (n=49).
- Intraoperative biopsies of the neurovascular bundle (NVB) were performed, guided by cognitive MRI or AR.
Main Results:
- While PSMs on the prostate surface were similar, 3D-AI-AR guided biopsies showed a significantly higher positivity rate (52% vs 13%), improving margin control.
- The 3D-AI-AR group had a lower overall PSM rate (22% vs 39%) and required less postoperative radiotherapy (18% vs 35%).
- Higher continence rates were observed in the 3D-AI-AR group at 12 months (91% vs 71%).
Conclusions:
- 3D-AI-AR guided biopsy during nerve-sparing RARP improves tumor identification and margin control.
- This technology shows promise for enhancing surgical precision and patient outcomes in RARP.
- Further long-term follow-up is needed to fully assess oncological and functional results.
