Purpose: The aim of this study was to compare the survival predictive values of the 1988 and 2009 FIGO staging systems for the staging of patients with early-stage endometrioid type endometrial cancer. Materials and Methods: Two hundred twenty-four patients treatedfor endometrial cancer from 1996 to 2006 at Ankara Oncology Education and Research Hospital were staged according to the two staging systems. Early-stage patients with a histological diagnosis of endometrioid adenocarcinoma were included in the study. The Kaplan-Meier method was used for survival analysis. Results: The charts of 224 patients treated for endometrial cancer were retrospectively evaluated. The five-year overall survival (OS) for Stage IA and IB cases was 100% (n = 19) and 96.2% (n = 79), respectively, with no significant difference between the OS values (p = 0.126) with the FIGO 1988 system and 96,4% (n = 112) and 87.5% (n = 48), respectively with a statistically significant difference (p = 0.05) with the FIGO 2009 system. Conclusion: The authors found that the survival prognostic value of the 2009 FIGO staging system was more effective than the 1988 FIGO staging system for cases with early-stage endometrioid type endometrial cancer.
