title: [Clinical significance of FIGO 2009 staging I and its prognostic related factors in endometrial carcinoma].
abstract: OBJECTIVE
  To discuss the clinical significance of Federation International of Gynecology and Obstetrics (FIGO) 2009 staging I and its prognostic related factors in endometrial carcinoma.
  
  
  METHODS
  A retrospective analysis was carried out on 233 cases with FIGO 2009 staging I endometrial carcinoma who were admitted to Department of Obstetrics and Gynecology, Peking University People's Hospital from Dec. 1998 to Dec. 2009 and were carried with complete staging operation then compared with FIGO 1988 staging. All follow-up data were complete.
  
  
  RESULTS
  Of the 233 cases, including FIGO 1988 staging I a 41 cases, I b 146 cases, I c 29 cases and II a 17 cases. The univariate analysis revealed that there were no significant difference between staging I a and I b group in histological grade, pathological type, intravascular vessel cancer embolus, the expression of ER, PR, postoperative chemotherapy or postoperative chemoradiotherapy (all P > 0.05). The univariate analysis revealed that there were no significant difference between staging I and II a group in histological grade, pathological type, intravascular vessel cancer embolus, the depth of myometrial invasion, the expression of ER and PR postoperative chemotherapy or postoperative chemoradiotherapy (all P > 0.05).
  
  
  CONCLUSIONS
  FIGO 2009 staging I in endometrial carcinoma is more consistent with the patient's clinical status than that in FIGO 1988 stage I and II a.
