title: A comparison of ovarian metastasis between squamous cell carcinoma and adenocarcinoma of the uterine cervix.
abstract: OBJECTIVE
  The purpose of our study was to investigate a possible difference in ovarian metastasis between squamous cell carcinoma and adenocarcinoma of the uterine cervix and to confirm clinicopathological variables associated with the metastases.
  
  
  METHODS
  Clinical and pathological variables of 1064 patients with invasive squamous cell carcinoma and 240 with adenocarcinoma were studied.
  
  
  RESULTS
  Ovarian metastasis was found in 14 patients (1.3%) with squamous cell carcinoma and 15 (6.3%) with adenocarcinoma. The mean age of patients with ovarian metastasis of squamous cell carcinoma was 57.4 years, compared to 50.2 years for adenocarcinoma. Ovarian metastasis of adenocarcinoma was more likely to be visible (40.0%) and present in both ovaries (66.7%), while these two characteristics occurred in only 21.4 and 36.7% of patients with squamous cell carcinoma. A logistic regression analysis with clinical variables indicated that clinical stage beyond IIb was a significant variable of squamous cell carcinoma, and more than 30-mm tumor size was significant in adenocarcinoma.
  
  
  CONCLUSIONS
  The incidence of ovarian metastasis of adenocarcinoma of the uterine cervix was significantly higher than that of squamous cell carcinoma. The incidence of adenocarcinoma was associated more closely with tumor size than clinical stage, whereas it was more associated with clinical stage in squamous cell carcinoma. The results thus suggested that the differences in ovarian metastases were caused by the different characteristics of the two types of carcinoma.
