title: Is stage I epithelial ovarian cancer overtreated both surgically and systemically? Results of a five-year cancer registry review.
abstract: OBJECTIVE
  To review the incidence of Stage I epithelial ovarian carcinoma in the West Midlands region and to identify prognostic factors that have a significant effect on survival.
  
  
  METHODS
  A retrospective review of all Stage I ovarian cancer patients registered from 1.1.80 to 31.12.84.
  
  
  METHODS
  West Midlands Regional Cancer Registry.
  
  
  METHODS
  457 patients with Stage I ovarian cancer--373 with epithelial ovarian carcinoma.
  
  
  METHODS
  Survival at censor date of 30.6.89.
  
  
  RESULTS
  28% developed recurrent disease, and the overall 5-year survival of the group was 70%. Univariate analysis of all possible prognostic factors showed that stage, adjuvant chemotherapy, histological grade and type, surgical rupture of the tumour, intact capsule histologically, clinical finding of ascites and the performance of peritoneal washings were significantly associated with survival. Adequate surgical staging as defined by FIGO was not significantly associated with survival. A multivariate analysis based on the Cox proportional hazard model identified histological grade, adjuvant chemotherapy, patient age and peritoneal washings as having independent prognostic effects. Surprisingly adjuvant chemotherapy and peritoneal washings had negative effects on survival.
  
  
  CONCLUSIONS
  Although a retrospective review has limitations, it would appear that adequate surgical staging and adjuvant chemotherapy confer no benefit in terms of survival in Stage I disease.
