Sentinel lymph node mapping in endometrial cancer: an updated review

Abstract

lymph node mapping (SLNM) is widely used in staging of both low-and high-risk early-stage endometrial cancer. It has a high detection rate, high sensitivity, high negative predictive value, and low false negative rate in detection of lymph node metastasis. Cervical injection of indocyanine green for SLNM is the preferred method. SLNM reduces the number of lymph node removal and reduces complications from lymphadenectomy without compromising oncological safety. This review discusses the latest evidence of SLNM in endometrial cancer staging in terms of technique, accuracy, limitations, impact on lymphadenectomy complications, and cancer survival.
