title: Prognostic factors in adult granulosa cell tumor of the ovary.
abstract: BACKGROUND
  The clinical course of adult granulosa cell tumor of the ovary is characterized by indolent growth tending toward late recurrence. A variety of clinical and pathologic parameters have previously been evaluated for prognostication with inconclusive results.
  
  
  METHODS
  The clinical records and tumor sections of 70 patients with adult granulosa cell tumors of the ovary were reviewed. Patients with recurrent tumors (REC) (n = 19) were compared with patients who remained without disease (NED) (n = 51).
  
  
  RESULTS
  Significant differences in stage and tumor size were noted between the two groups; however, after logistic regression analysis, only stage remained statistically significant. Pathologic evaluation revealed that Call-Exner bodies occurred more frequently in tumors of the NED patients. Cellular atypia and high mitotic rates were more frequent in the REC group; however, after logistic regression analysis, only atypia remained statistically significant. When early (< 10 years) and late recurring tumors (> 10 years) were compared, statistically significant differences were again noted: early recurring tumors had fewer Call-Exner bodies, higher mitotic rates, and higher degrees of atypia; late recurring tumors were similar to tumors in the NED patients.
  
  
  CONCLUSIONS
  Tumor stage and, to a lesser extent, tumor size are the only clinical parameters of prognostic importance in adult granulosa cell tumors. Cellular atypia and, to lesser extents, mitotic rate and the absence of Call-Exner bodies are the only significant pathologic prognosticators. It is difficult to predict early recurrences and impossible to predict late recurrences using these clinical and pathologic parameters.
