Dioun S, Chen L, Melamed A, et al. - Researchers conducted the study for analyzing the utilization, morbidity, and cost of sentinel lymph node mapping in women undergoing hysterectomy for complex atypical endometrial hyperplasia. From 2012 to 2018, women with complex atypical endometrial hyperplasia who had a hysterectomy in the Perspective database were examined. Among 10,266 women, sentinel lymph node mapping was conducted in 620 (6.0%), lymph node dissection in 538 (5.2%), and no lymphatic evaluation in 9,108 (88.7%). Sentinel lymph node mapping ($9,673) and lymph node dissection ($9,754) had higher median costs than in those who did not undergo nodal assessment ($8,435). Sentinel lymph node mapping is becoming more common among women with complex atypical endometrial hyperplasia, but it is not linked to a rise in perioperative morbidity or mortality.
