Introduction:
This study was performed to evaluate the safety and efficacy of lymph node dissection (LND) during robot-assisted radical cystectomy (RARC) compared with open radical cystectomy (ORC).
Methods:
From October 2003 to December 2021, 122 patients underwent LND during RARC and 103 patients underwent LND during ORC at Tokushima University Hospital and Tokushima Prefectural Central Hospital. We investigated the safety and efficacy of LND during RARC by comparing the surgical and oncological outcomes between the two groups.
Results:
The patients were significantly older in the RARC than the ORC group. The operative time was significantly shorter and the estimated blood loss was significantly lower in the RARC than the ORC group. Although the lymph node yield was significantly higher in the RARC than the ORC group, there was no significant difference in lymph node positivity between the groups. There was no significant difference in the incidence of local recurrence or distant metastasis between the two groups. The 5-year survival rates (overall survival, cancer-specific survival, and recurrence-free survival) were not different between the RARC and ORC groups.
Conclusion:
This study suggests that the surgical and oncological safety and efficacy of LND during RARC are greater than those of LND during ORC. We believe that LND during RARC is a higher-quality procedure than LND during ORC.
