We evaluated the impact of lymphadenectomy on overall survival and relapse-free survival for patients with intermediate risk endometrial cancer.Methods We retrospectively reviewed patients from the FRANCOGYN database with intermediate risk endometrial cancer, based on pre-operative and post-operative criteria (type 1, grade 1–2 tumors with deep (> 50%) myometrial invasion and no lymphovascular space invasion), who received primary surgical treatment between November 2002 and August 2013. We compared overall survival and relapse-free survival between staged and unstaged patients.Results From 1235 screened patients, we selected 108 patients with intermediate risk endometrial cancer. Eighty-two (75.9%) patients underwent nodal staging (consisting of pelvic +/- para-aortic lymphadenectomy). Among them, 35 (32.4%) had lymph node disease. The median follow-up was 25 months (range 0.4 to 155.0). The overall survival rates were 82.5% for patients staged (CI 64.2 to 91.9) vs 77.9 % for unstaged patients (CI 35.4 to 94.2) (P = 0.73). The relapse-free survival rates were 68.9% for staged patients (CI 51.2 to 81.3) vs 68.8% for unstaged patients (CI 29.1 to 89.3) (P=0.67).Conclusion Systematic nodal staging does not appear to improve overall survival and relapse-free survival for patients with IR EC but could provide information to tailor adjuvant therapy. Sentinel lymph node dissection may be an effective and less invasive alternative staging technique and should provide a future alternative for this population.
