Introduction/Background*The aim was to provide long-term outcome data in endometrial cancer patients undergoing robot-assisted laparoscopic surgery and sentinel lymph node (SLN) mapping.

Methodology Retrospective cohort study of 108 patients with primary endometrial cancer who underwent robot-assisted laparoscopic surgery and sentinel lymph node mapping using the Memorial Sloan Kettering Cancer Center algorithm with near-infrared fluorescence detection of indocyanine green for endometrial cancer from November 20th 2012 to January 1st 2016 at St. Olavs hospital in Norway. The primary endpoint was recurrence-free survival. Secondary endpoints were overall survival and treatment complications.

Result(s)*After a median follow up of 75 months (range 61-98), five (4.6%) patients had recurred and three patients had died from the disease. The 5-year recurrence-free survival was 95.4% (95% CI, 91.5 – 99.3). The 5-year disease specific survival was 97.2% (95% CI, 94.1 – 100.3). Four of the patients with recurrent disease had lymph node metastasis at diagnosis. The 5-year overall survival was 92.6% (95% CI, 87.7 – 97.5). Peripheral neuropathy after chemotherapy was the most common complication (9.3%), followed by lower limb edema (2%) and postoperative hernia (2%).

Conclusion*The present study demonstrated excellent oncologic outcome and few treatment complications in patients treated according to the SLN algorithm more than five years after diagnosis.
