Abstract

PURPOSE
The aim of this study is to evaluate the safety of fertility-sparing surgery as the treatment for patients with primary mucinous epithelial ovarian cancer.
MATERIALS AND METHODS
A retrospective study of patients with mucinous ovarian cancer between 1991 and 2010 was performed. The demographics and survival outcomes were compared between patients who underwent fertility-sparing surgery and those who underwent radical surgery.
RESULTS
A total of 110 patients underwent primary surgery. At the time of surgery, tumors appeared to be grossly confined to the ovaries in 90 patients, and evidence of metastasis was definite in 20 patients. Of the 90 patients with tumors that appeared to be grossly confined to the ovaries at surgical exploration, 35 (38.9%) underwent fertility-sparing surgery. The Kaplan- Meier curve and the log rank test showed no difference in either recurrence-free survival (p=0.792) or disease-specific survival (p=0.706) between the two groups. Furthermore, there was no significant difference in recurrence-free survival (p=0.126) or disease-specific survival (p=0.377) between the two groups, even when the analysis was limited to women below the age of 40. In a multivariate Cox model, fertility-sparing surgery had no effect on either recurrence-free survival (recurrence hazard ratio [HR], 1.20; 95% confidence interval [CI], 0.25 to 5.71) or disease-specific survival (death HR, 0.88; 95% CI, 0.17 to 4.60).
CONCLUSION
Fertility-sparing surgery in primary mucinous cancer grossly confined to the ovaries may be a safe option and one not associated with an increase in recurrence or mortality.
