Summary
Intraoperative frozen section (IFS) analysis reliably monitors nerve sparing during laparoscopic prostatectomy. This technique helps surgeons preserve potency by reducing positive surgical margins without compromising cancer control.
Area of Science:
- Urology
- Surgical Oncology
- Pathology
Background:
- Nerve-sparing radical prostatectomy aims to preserve erectile function.
- However, this approach can increase the risk of positive surgical margins.
- Monitoring nerve preservation during surgery is crucial.
Purpose of the Study:
- To evaluate the utility of intraoperative frozen section (IFS) analysis.
- To assess its role in monitoring nerve-sparing laparoscopic prostatectomy.
- To determine its impact on surgical margins and cancer control.
Main Methods:
- 100 patients with localized prostate cancer underwent nerve-sparing laparoscopic prostatectomy with IFS.
- Tissue wedges from neurovascular bundles (NVBs) were analyzed intraoperatively.
- NVBs were resected if positive margins were detected on frozen section.
Main Results:
- IFS analysis identified positive margins in 24 patients, confirmed by permanent sections.
- Overall positive margin rates decreased from 33% to 12% (and 26.1% to 7.9% for pT2 tumors) with IFS.
- Tumor involvement of NVBs was found in 8 cases (33%) requiring resection.
Conclusions:
- IFS is a reliable method for monitoring nerve sparing during laparoscopic prostatectomy.
- It enables surgeons to perform nerve-sparing procedures more frequently.
- This approach can be achieved without compromising oncological outcomes.
