Objective: The objective of this study was to compare the oncologic outcomes between those who underwent robotic surgery or conventional laparoscopic surgery for endometrial cancer. Method: We performed a retrospective review of patients from a single institution who underwent either laparoscopic or robotic surgery for the treatment of endometrial cancer between January 2010 and December 2020. Tumor characteristics, recurrence rate, disease-free survival, and overall survival were compared according to surgical approach. Results: Among the 268 patients included in this study, 95 underwent robotic surgery (35.4%) and 173 underwent laparoscopic surgery (64.6%). The median follow-up durations were 51 and 59 months for the robotic surgery and laparoscopic surgery groups, respectively (p = 0.085). The recurrence rate did not differ significantly between the two groups. (p = 0.371). Disease-free survival (p = 0.721) and overall survival (p = 0.453) were similar between the two groups. In both univariate and multivariate analyses, the type of surgery was not related to disease-free survival. The median total cost per admission was significantly higher for RS than for LS (12,123 vs. 6,884 USD, p < 0.0001). Conclusion: With consistently greater costs and similar survival outcomes, robotic systems have few advantages compared with laparoscopy.
