Abstract

Objective

The standard therapy for high-grade endometrial cancer is surgery but the therapeutic effects of pelvic and paraaortic lymph node dissection (LND) are poorly investigated. In this study, we retrospectively evaluated overall survival, recurrence rates and recurrence-free survival among patients with high-grade type I and II endometrial carcinoma who underwent LND.

Methods

This study included 284 patients who are recorded in the German Tumor Centre Regensburg form 1998 to 2015 and were selected by cancer grading, the absence of secondary tumors, primary surgery including hysterectomy and available follow-up. 244 of the 284 patients in this cohort were unequivocally classified as R0 after resection.

Results

A significantly increased overall survival was observed for systematic LND of 25 or more paraaortic and pelvic lymph nodes versus patients who did not undergo such intervention (p < 0.001) or had elective LND of 1–24 lymph nodes both in univariable (p = 0.016) and multivariable (p = 0.014) analysis. A similar observation was made for recurrence-free survival of patients in the cohort who underwent complete tumor resection (R0). In addition, a reduced cumulative recurrence rate was observed for patients with systematic LND.

Conclusions

Our study provides evidence that the systematic removal of 25 or more pelvic and paraaortic lymph nodes reduces the recurrence rate and that it is beneficial for the long-term overall and recurrence-free survival of patients with high-grade endometrial cancer.
