Sentinel lymph node mapping with staging lymphadenectomy for patients with endometrial cancer increases the detection of metastasis.

Objectives: To compare the performance of sentinel lymph node (SLN) mapping with staging lymphadenectomy versus staging lymphadenectomy alone for the detection of metastasis and the use of adjuvant therapies in patients with endometrial cancer.

Methods: All patients with apparent early-stage endometrial cancer (n=780) who underwent robotic-assisted hysterectomy with pelvic±aortic lymphadenectomy from July-2006 to June-2013 were compared [pelvic±aortic lymphadenectomy (n=661) versus SLN-mapped cases with pelvic±aortic lymphadenectomy (n=119)]. Isosulfan-blue and indocyanine-green with near-infrared imaging were used for SLN mapping.
