Standard surgical staging was performed with lymphadenectomy in 130 cases. Mean age was 63 years (27–94). Pathology most common was endometrioid adenocarcinoma (84.5%). Most frecuent FIGO stage was IA (47.8%). Mean follow-up was 46 months. The factors that impact on survival were compared using univariate and multivariate analysis.Results The estimated 5-year DFS and OS comparated rates were respectively according to FIGO local stages (I) 93.9 and 90.2%, vs advanced stages (II–IV) 0 and 53.7% (p=0.00 Hazard ratio 5.58 (CI 95%, 2.74–11.35) and p=0.00 Hazard ratio 4.19 (CI 95%, 2.11–8.34), histological type I 92.3 and 89%, vs type II 28.1 and 58.3%% (p=0.00 Hazard ratio 2.91 (CI 95%, 1.3–6.57) and p=0, 01 Hazard ratio 2.6 (CI 95%, 1.17–5.77), histological low grade (G1) 89.1 and 92%, vs high grade (G2-3) 15.9 and 55.7% (p=0.00 Hazard ratio 5.79 (CI 95%, 2.42–13.85) and p=0.00 Hazard ratio 2.68 (CI 95%, 1.25–5.74); myometrial infiltration <50% 92.5 and 92.9%, vs >50% 63.9 and 66.1 (p=0.00 Hazard ratio 3.7 (CI 95%, 1.73–7.91) and p=0.00 Hazard ratio 4.31 (CI 95%, 1.92–9.7); in the abscence of lymphovascular space invasión (LVSI-) 94.4 and 89.7%, vs LVSI+ 0 and 62.6% (p=0.00 Hazard ratio 5.88 (CI 95%, 2.92–11.85) and p=0.01 Hazard ratio 2.4 (CI 95%, 1.17–4.89); lack of cervical stromal invasion 94.3 and 91.4%, vs present 26.6 and 87.8% (p=0.00 Hazard ratio 4.33 (CI 95%, 1.54–12.12) and p=0.63) and tumor size <2 cm 88.1 and 89.9%, vs tumor size >2 cm 64.9 and 78.2% (p=0.00 Hazard ratio 4.02 (CI 95%, 1.33–12.15) and p=0.12).Conclusion The knowlegde of the histologic parameters is critical to the management of the EC.Disclosure Nothing to disclose.Abstract EP572 Figure 1 Disease-Free Survival (DFS) for lymphovascular space invasion (A) and Overall survival (OS) for histAbstract EP572 Figure 2 Overall survival (OS) for miometrial invasion (A).
