The risk of lymph nodal metastases in endometrial cancer varies greatly according to the characteristics of the primary tumor. Surgical staging with a systematic lymphadenectomy in endometrial cancer is debated since three decades. On one hand, it provides important pathological information on the spread of the tumor allowing for an appropriate decision making on adjuvant treatment but on the other side it is characterized by a non-negligible short and long-term morbidity. In the past decade, various efforts have been made in the attempt to apply the concept of the sentinel lymph node mapping in endometrial cancer. The sentinel lymph node mapping has the potential to provide the necessary pathological lymph nodal information at a reasonable cost in terms of morbidity. In this review, the most relevant aspects of the sentinel lymph node mapping in endometrial cancer are summarized. Furthermore, the performance in terms of false negative rates and detection rates, the clinical value of the pathological ultrastaging, its clinical applicability in different scenarios including patients preoperatively considered to be at low or at high risk are discussed. Oncological outcome of the patients who have been submitted to a sentinel lymph node mapping as compared to a full lymhadenectomy are presented as well as technical aspects to improve the performance of the surgical technique.
