Abstract

Introduction: Controversy persists on the benefit of para-aortic lymphadenectomy in patients with early-stage endometrial cancer, for some trials suggest increased morbidity and costs showing no clear benefit for overall survival.  Objective: to determine para-aortic lymph node metastases (LNM) in patients with early-stage endometrial cancer according to the Kumar et al. risk classification algorithm.  Method: a case series descriptive retrospective study was conducted in patients who underwent open or laparoscopic staging surgical procedures (total hysterectomy, bilateral salpingo-oophorectomy and pelvic and para-aortic lymphadenectomy), diagnosed with endometrioid endometrial adenocarcinoma, classified by the risk algorithm and analysis of their outcomes. Results: a total of 15 patients were included, of the 9 patients classified as high risk by the Kumar et al algorithm, 2 (28.5%) had para-aortic LNM, and no patients in the low risk group had LNM. Four (26.6%) patients had postoperative complications, 75% were early complications, one patient was admitted to the intensive care unit (ICU) and there were no deaths related to the surgical procedures. Conclusion: low risk patients classified by the Kumar et al algorithm had no para-aortic LNM however high risk patients had different results. We cannot therefore recommend routine para-aortic lymphadenectomy. Further prospective clinical trials must be conducted for validation of this algorithm with the same number of patients with which it was proposed.
