ABSTRACT
Purpose@#Population-based comparisons between minimally invasive surgery (MIS) (robotic surgery [RS] and laparoscopic surgery [LS]) and open surgery (OS) for managing endometrial cancer are lacking. This study aimed to compare surgical and oncologic outcomes between endometrial cancer patients who underwent surgical staging via MIS or OS. @*Materials and Methods@#A population-based retrospective cohort study was performed using claims data from the Korean National Health Insurance database from January 2012 to December 2016. All patients who underwent hysterectomy under diagnosis of endometrial cancer were identified. Patients were classified into RS, LS, and OS groups. Operative and oncologic outcomes were compared among the three groups after adjustments for age group, risk group (adjuvant therapy status), modified Charlson comorbidity index, income level, insurance type, and index year using propensity scores obtained via the inverse probability of treatment weighted method. @*Results@#After adjustment, 5,065 patients (RS, n=315; LS, n=3,248; OS, n=1,503) were analyzed. Patient demographics were comparable. Hospital stay, postoperative complications, and cost were more favorable in the RS and LS groups than in the OS group (all p < 0.001). Five-year overall survival was significantly longer in the RS and LS groups than in the OS group (94.8%, 91.9%, and 86.9%, respectively; p < 0.001). Moreover, the survival benefit of RS was shown in the subgroup analysis of low-risk endometrial cancer patients. @*Conclusion@#Our study provides further evidence for the RS being a safe surgical alternative to the LS and OS, especially in low-risk endometrial cancer patients, offering surgical and oncologic outcomes equivalent to other surgical approaches.
