This multicenter randomized trial compared the long-term oncologic outcomes of the KangDuo surgical robot KD-SR-01 and the da Vinci Xi in 100 patients undergoing colorectal cancer resection. At three years, disease-free survival (DFS) rates were 85.3% for KD and 85.5% for DV, while overall survival (OS) was 100.0% for KD and 94.0% for DV, with no significant differences observed.
Key findings
- 3-year disease-free survival rates were 85.3% for KD and 85.5% for DV (P=0.995).
- 3-year overall survival rates were 100.0% for KD and 94.0% for DV (P=0.606).
- The DFS hazard ratio comparing KD with DV was 0.918 (P=0.881).
Why it matters
Understanding the long-term oncologic outcomes of different robotic systems in colorectal cancer resection is crucial for surgical decision-making and patient management. This study provides evidence that both systems yield comparable results.
