Update of sentinel lymph node mapping assessment in endometrial cancer

Abstract

Endometrial cancer is the most common gynecologic malignancy in developed countries. Pathologic confirmation of lymph node metastasis is important for risk stratification and the administration of adjuvant treatments. Therefore, comprehensive, systematic lymphadenectomy has been routinely performed but has been associated with various morbidities. Meanwhile, the concept of sentinel lymph node (SLN) mapping and biopsy has emerged and is now accepted as an alternative to conventional systematic lymphadenectomy in early-stage endometrial cancer. For better management of endometrial cancer, we conducted a literature review to summarize the role and diagnostic accuracy of the SLN mapping strategy in endometrial cancer. Evidence from the monumental and recent literature and ongoing clinical trials will be introduced.
