Endometrial cancer remains the most common malignancy of the female genital tract. Lymph node metastasis is one of the most important prognostic factors and stratification into pelvic lymph node invasion (stage IIIC1) and para-aortic lymph node invasion (stage IIIC2) improved the predictive value of the 2009 FIGO classification.Radiological examination such as magnetic resonance imaging and positron emission tomography-computed tomography do not have good enough sensitivity to avoid lymphadenectomy for the assessment of lymph node invasion. Prediction scores are becoming more and more valuable to exclude lymph node metastasis in low risk groups and biomarkers could help to identify patients with high risk lymph node metastatic probability.The therapeutic role of lymph node dissection remains debated. Several endpoints can be considered to evaluate the opportunity of lymphadenectomy in endometrial cancer.Firstly, we compare survival according to the realization, the extent and the numbers of nodes removed during lymphadenectomy. Secondly, we assess the opportunity of lymphadenectomy in order to tailor adjuvant treatment modalities. Thirdly, we analyze the surgical complication rate after pelvic lymphadenectomy.
