abstract: OBJECTIVE
  To investigate the clinical and pathological characteristics of epithelial ovarian carcinoma in patients with age under 40.
  
  
  METHODS
  From Jan 1978 to Dec 1992, 54 cases with epithelial ovarian carcinoma under 40 years old were admitted to our hospital and enrolled in the study group, another 54 patients suffered from the same disease with age over 40 in the same period were served as control. Comparison analysis for clinical and pathologic data of 2 groups was performed using SPSS and SURVALC statistics software.
  
  
  RESULTS
  Main complaint because of either pelvic mass or abdominal mass found by chance was more common in study group (46.3%) than that in control group (27.8%). whereas because of symptoms was less common in study group (53.7%) than in control group (72.2%). Other parameters such as early stage (I and II) rate (61.1%), unilateral tumor rate (68.5%), average maximum diameter of tumor (13.6 cm), highly differentiated rate (50%) and the possibility for tumor reductive surgery were higher in study group than in control group. The difference of histological pattern and chemotherapy between 2 groups was not significant. Single variate analysis showed that the prognosis was better in study group. The 2-year and 5-year survival rates were 69.8% and 50.2% respectively. No recurrence was found in the 8 patients in whom the contralateral healthy ovary remained. However multiple variate analysis indicated that age was not a prognostic factor.
  
  
  CONCLUSIONS
  Epithelial ovarian carcinoma was prone to be lower degree malignancy in patients under 40 years therefore the prognosis of them was better. It might be resonable to have healthy ovary left in some select cases.
