Long-term oncological outcomes of laparoscopic partial nephrectomy

Area of Science:

• Urology
• Surgical Oncology
• Minimally Invasive Surgery

Background:

• Open partial nephrectomy (OPN) has been the gold standard for small renal tumors.
• Laparoscopic partial nephrectomy (LPN) offers potential morbidity benefits but requires oncologic validation.
• Evaluating LPN's oncologic efficacy against established OPN outcomes is crucial for its widespread adoption.

Purpose of the Study:

• To review the most recent oncologic outcomes of laparoscopic partial nephrectomy (LPN).
• To compare LPN's oncologic results with published data from open partial nephrectomy (OPN) series.
• To assess the suitability of LPN as a standard of care for renal tumors.

Main Methods:

• Systematic review of recent literature on LPN oncologic outcomes.
• Analysis of 5-year follow-up data for LPN.
• Comparison of LPN recurrence rates and survival with historical and contemporary OPN data for pT1 tumors.

Main Results:

• Recent 5-year follow-up data show LPN achieves cancer-specific survival rates comparable to OPN.
• Low margin positivity rates have been consistently demonstrated in LPN series.
• Local and distant recurrence rates for LPN are acceptably low and align with OPN controls.

Conclusions:

• Laparoscopic partial nephrectomy is emerging as a standard of care for select small renal tumors at high-volume centers.
• Expertly performed LPN at high-volume centers duplicates the oncologic outcomes of open surgery.
• Longer-term (10-year) data and multi-institutional validation are needed to fully establish LPN's long-term efficacy.
