title: [DNA content and cell cycle phase analysis in uterine sarcomas and its clinical significance].
abstract: OBJECTIVE
  To investigate the relationship among DNA content, cell cycle phase analysis with the clinical-pathological features and prognosis of uterine sarcomas.
  
  
  METHODS
  DNA content and cell cycle phase analysis were performed on 75 paraffin-embedded specimens of uterine sarcomas using flow cytometry.
  
  
  RESULTS
  Both the aneuploidy rate and DNA index (DI) in specimens from advanced stage and poorly-differentiated cases were significantly higher than those in specimens from early stage and well-differentiated cases (P < 0.05). S-phase fraction (SPF) and proliferation index (PI) were significantly higher in advanced stage than those in early stage (P < 0.05). The 5-year suvival rates for DNA aneuploid and diploid patients were 27% and 76%, respectively (P < 0.01). The 5-year suvival rates for patients with a SPF > 20% and those with SPF < or = 20% were 10% and 56% respectively (P < 0.01).
  
  
  CONCLUSIONS
  DI, SPF, PI and clinical stage are the most important factors affecting the prognosis.
