Summary
Robotic retroperitoneal lymph node dissection (RPLND) for testicular cancer shows a learning curve, with improved outcomes as surgeons gain experience. This minimally invasive approach is safe and effective, especially in specialized centers.
Area of Science:
- Urology
- Surgical Oncology
- Minimally Invasive Surgery
Background:
- Retroperitoneal lymph node dissection (RPLND) is essential for testicular cancer management but carries high morbidity.
- Minimally invasive techniques, particularly robotic surgery, are increasingly adopted for RPLND.
- Analyzing outcomes of robotic RPLND (R-RPLND) is crucial for understanding its evolving role.
Purpose of the Study:
- To evaluate perioperative and postoperative outcomes of robotic RPLND (R-RPLND) in testicular cancer.
- To identify trends and the learning curve associated with an increasing volume of R-RPLND procedures.
- To assess factors influencing operative time, hospital stay, and complication rates.
Main Methods:
- Retrospective analysis of 30 R-RPLNDs performed between 2020 and 2024.
- Logistic regression used to analyze operative time, hospital stay, blood loss, lymph node yield, and complications (Clavien-Dindo).
- Patients grouped by case number (1-10, 11-20, 21-30) to assess learning curve effects using Kruskal-Wallis test.
Main Results:
- Operative time significantly decreased with increasing case number (p < 0.001).
- Hospital stay was significantly influenced by overall complications (p = 0.0006).
- Two major perioperative complications (6.6%) were observed; no predictive factors for complications were identified.
Conclusions:
- R-RPLND for germ cell tumors (GCTs) demonstrates a significant learning curve, improving efficiency and potentially reducing complications.
- The procedure shows promise as a safe and effective treatment for GCTs when performed by experienced surgeons.
- Low complication rates suggest R-RPLND is a viable option, particularly in specialized high-volume centers.
