title: Is the 2009 FIGO staging system really valuable for stage I endometrial cancer?
abstract: OBJECTIVE
  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.
  
  
  METHODS
  Two hundred twenty-four patients treated for 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.
  
  
  CONCLUSIONS
  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.
