ASO Visual Abstract: Comparison of Minimally Invasive and Open Surgery for the Treatment of Endometrial Cancer with a High Risk of Recurrence: A Propensity-Score-Matching Study in Korea and Taiwan

This study compared oncologic outcomes between minimally invasive surgery (MIS) and open surgery for the treatment of endometrial cancer with a high risk of recurrence. This study included patients with endometrial cancer who underwent primary surgery at two tertiary centers in Korea and Taiwan. Low-grade advanced-stage endometrial cancer (endometrioid grade 1 or 2) or endometrial cancer with aggressive histology (endometrioid grade 3 or non-endometrioid) at any stage was considered to have a high risk of recurrence. We conducted 1:1 propensity score matching between the MIS and open surgery groups to adjust for the baseline characteristics. Of the total of 582 patients, 284 patients were included in analysis after matching. Compared with open surgery, MIS did not show a difference in disease-free survival [hazard ratio (HR) 1.09; 95
