The 2018 NCCN Guidelines indicates prospective or retrospective studies have shown that compared with radical lymphadenectomy, that sentinel lymph node identification and pathologic ultra-staging may increase the detection rate of lymph node metastasis with a lower false-negative rate in patients whose lesions are significantly confined to the uterus. Indocyanine green (ICG) fluorescence provides a high detection rate of sentinel lymph nodes and has been routinely applied。
